From Human Bones to Food: Another Soylent Green

A new book “Bones of Contention: The Industrial Exploitation of Human Bones in the Modern Age” argues that in the19th century human bones became a sought-after raw commodity. Scientists had just discovered its usefulness of human bones for agriculture as a source of phosphates for fertilizers and for the sugar industry, the use of bone char for beet sugar processing.

The high demand for these ingredients had one major unexpected consequence: the plundering of cemeteries and battlefields …in Britain, France, Belgium, Germany, Austria, Algeria and the United States. When countries out of bones in Europe, they turned to their colonies. The French plundered cemeteries in Algeria and shipped the bones to sugar factories in Marseilles. The British imported mummies and bones from Egypt on an industrial scale…

Who Craves Baby Eels: the Industry and its Black Market

The growing craving for eel over the decades, concurrent with the rise of China’s middle class, has triggered overfishing in Japan and Europe, leading to a decline in the species’ population. The European Union banned the import and export of eels in 2010, which led seafood wholesalers to look for alternative sources, bringing the trade—and thousands of poachers—to Canada… Fishermen say elver poachers outnumbered licensed harvesters 10-to-1 during the 2023 abbreviated season, closed after 18 days due to concerns about illegal fishing.

There is a lot of money at stake. Fishers use mesh nets to scoop up baby eels as they enter Canada’s east coast river systems, and sell them on to aquaculture operations in Asia to raise them until they are ready for market. Baby eell demand “has resulted in unsustainable eel fishing,” according to a Justice Department indictment filed in 2022 with the U.S. District Court of New Jersey, in relation to charges filed against a seafood distributor and eight of its employees—four of whom are based in China—on allegations of illegally trafficking large volumes of juveniles. “A multibillion-dollar international black market for freshwater eels flourishes.” At its peak, a pound of elvers fetched about $1,800, but fishers say the price has dropped due to black-market activity…

It is difficult to stamp out illegal harvesting entirely. Officials say it happens in the evening and often in isolated locations. The barrier to entry is low, because all poachers need is a pair of rubber boots, a headlight, and a good-quality dip net purchased from a sporting goods store. Illegally-caught baby eels can still be packaged and shipped to Hong Kong in mislabeled boxes, mixed either with legally-caught eels or other seafood, like lobster, officials say.

When Lakes Become a Soup of Minerals: the Fate of Great Salt Lake

In the summer 2024, a California startup plans to start construction on a project to suck up water from the Great Salt Lake, Utah, United States to extract one of its many valuable minerals: lithium, a critical ingredient in the rechargeable batteries used in electric vehicles. The water will then be reinjected back into the lake, which Lilac Solutions says addresses concerns about the damaging effects of mineral extraction. At its peak, Lilac says it will use a series of pipes to suck up 80,000 gallons of water a minute to harvest the mineral. The company plans to eventually produce up to 20,000 tons of battery-grade lithium a year.

The effort is one of dozens of projects across the U.S. racing to build up a domestic supply of lithium and other battery minerals as the Biden administration is dedicating billions of dollars to strengthening the U.S. battery supply chain and reducing reliance on China, which dominates the global production of battery minerals.

One common extraction method of lithium pumps briny underground water into vast man-made ponds, where evaporation separates lithium from other elements over 18 months or more. Mining companies in Chile and elsewhere have used the approach, which drains scarce water resources and can leave deposits of toxic residues.

Lilac says its technology is much faster, taking a matter of hours from the time of extraction, while preserving water levels. Its method deploys reusable ceramic “beads” that attach to lithium atoms to separate them from the brine.

At the Great Salt Lake, mineral extraction is nothing new. The lake has been shrinking for decades because of agricultural, industrial and other diversions of its feed waters. Extraction of minerals accounts for about 13% of its water diversion, according to a 2019 study. Meanwhile, the lake has become a concentrated soup of minerals, since it doesn’t have an outlet that lets it discharge the ones that flow into it.

Food Security: The Silicon Valley of Seeds

The Communist Party’s top disciplinary body—after punishing graft in the military, domestic security organs and the financial sector—is now hunting officials, merchants and farmers it suspects of harvesting illicit profits from trade in grains and seeds. Tasked with being more forceful in safeguarding the nation’s “seed security,” authorities have investigated dozens of cases involving seed-related misconduct and, in several instances, imprisoned grain-sector officials on corruption charges…Officials say the goal is to stop the proliferation of fake and substandard seeds that could jeopardize food production and safety, while punishing officials, merchants and farmers who siphon agricultural subsidies and peddle low-grade seeds.

Xi has often highlighted food security as a national interest, calling on officials to ensure that China can fully nourish its 1.4 billion people. His demands have taken on greater urgency in recent years as he pushed to prepare his country for a potential confrontation with the U.S.—a major source of Chinese grain imports, including soybeans and corn—and forestall disruptions to food supplies for one of the world’s most populous nations…Today, Beijing sees the seed sector as one of several strategic industries where Western powers could flex their technological superiority to strangle a lagging China. Demonstrating his personal interest in this field, Xi has twice visited a seed-breeding base in the island province of Hainan that officials call the “Silicon Valley” of China’s seed industry.

China is the world’s largest grain producer, growing one-quarter of global supply on less than 10% of the world’s arable land. But its ability to feed its own people has slipped over recent decades by some estimates. ..Officials and state media have taken to comparing seeds to advanced semiconductor chips, a technology that China has pledged to master in its quest for a national renaissance…While China’s seed industry is strong enough to survive foreign strangulation, the country still falls behind in seed quality, according to the Farmers’ Daily, which recommended measures including “resolutely cracking down” on the trading of fake and mislabeled seeds, whereby officials and merchants defraud farmers with counterfeit or lower-grade goods marked as top-quality seeds….

Bickering is Easier than Acting: Saving Biodiversity

At the COP15 biodiversity summit in Canada in December 2022, more than 190 countries agreed to the Kunming-Montreal Global Biodiversity Framework, a deal including targets such as nations protecting and restoring 30% of the world’s land and seas by 2030. To ensure that all countries — particularly low- and middle-income nations (LMICs) — can meet these targets, those that signed the deal agreed to establish a trust fund by the end of this year and that, by 2030, wealthy nations should collectively be contributing US$30 billion per year. Disputes have re-emerged, however, on whether the trust fund should be independent or should be established under the auspices of the Global Environment Facility. Because LMICs don’t have an adequate say in how the GEF funds are spent, LMICs want the trust fund to be established as an independent fund.

These tensions could delay the trust fund’s adoption, which was planned for a GEF assembly in August 2023, delaying biodiversity action even more … Meanwhile, the clock is ticking: researchers have estimated that one million species are under threat of habitat loss because of factors such as climate change and agriculture.

The Shameful Mismanagement of the Murray-Darling River: Australia

Millions of fish have died in the Darling River near his town, Menindee, in outback New South Wales, Australia in March 2023. After days under the sun, their bodies had started to “break up…transforming the river that locals rely on for drinking and showering into an ecological wasteland. Authorities have said the mass death was caused by a lack of oxygen in the water, called hypoxia, a result of recent floods and a heat wave. But furious locals say the true root of the problem is the overuse of Australia’s biggest and most vital river system.

The disaster is the latest episode in a long-running battle over the Murray Darling Basin, a vast network of lakes and rivers stretching across four states in eastern Australia, which sustains much of the country’s agriculture and dozens of communities along its banks. In an arid country where social, economic and environmental interests clash whenever water runs scarce, the issue has pitted states against each other, and riverside communities against farms upstream.

The 2019 fish deaths happened during a drought and the 2023 fish deaths happened after a flood, said Richard Kingsford, the director of the Center for Ecosystem Science at the University of New South Wales. But, he said, the long-term causes were the same both times: “There’s not enough water in the river, and the whole system is engineered so that escape routes are closed.” Over-extraction means parts of the river run dry more often, he said, and the small and medium-sized floods that used to periodically clear away organic debris have all but disappeared. That means when a big flood hits, that debris is all swept into the river, where it breaks down and deoxygenates the water. That, combined with the construction of weirs that have prevented the fish from swimming to better-oxygenated water, has made this disaster worse, he said….

The New South Wales fisheries and water management bodies, by contrast, both attribute the disaster to weather-related causes…

After many of the fish had already sunk to the bottom of the river, the cleanup started with workers in small boats removing floating carcasses with hand-held nets. Authorities said this will be followed by machinery that will drag nets through the river to scoop up sunken fish….

Miracles Performed by Wild Crops

Grains that grow year after year without having to be replanted could save money, help the environment, and reduce the need for back-breaking labor. Now, the largest real-world test of such a crop—a perennial rice grown in China—is showing promise. Perennial rice can yield harvests as plentiful as the conventional, annually planted crop while benefiting the soil and saving smallholder farmers considerable labor and expense, researchers have found…

All rice is perennial to some extent. Unlike wheat or corn, rice roots sprout new stems after harvest. The trouble is that this second growth doesn’t yield much grain, which is why farmers plow up the paddies and plant new seedlings. The improved perennial rice, in contrast, grows back vigorously for a second harvest. Researchers developed it by crossing an Asian variety of rice with a wild, perennial relative from Nigeria. Improving the offspring took decades, and in 2018 a variety called Perennial Rice 23 (PR23) became commercially available to Chinese farmers. This was a “scientific breakthrough,” says Koichi Futakuchi, a crop scientist at the Africa Rice Center…

Over 4 years PR23 averaged 6.8 tons of rice per hectare, slightly higher than the annual rice, they report today in Nature Sustainability. As hoped, the perennial crop tended to grow back again and again without sacrificing the size of the harvest. In the fifth year, however, the yields of PR23 declined for some reason, suggesting it needed to be replanted. The perennial rice also improved the soil.

Researchers note potential risks. Because PR23 enables farmers to till less, fungi and other pathogens can build up in the fields. Insects can persist in the stubble after harvest, because it’s not plowed under, then transmit viruses when they feed on the regenerating sprouts in the spring. And without tilling, weeds can flourish; the researchers found that fields with PR23 needed one to two more herbicide treatments than regular rice. They also note that it’s more work to resow the perennial rice when its yield falters, because its larger and deeper roots need to be killed.

Reversing Industrialization: the Future of Plants?

Is it possible that the microbiomes of ancestors of our crops can be used to “rewild” microbiomes of current crops reinstating their diverse microbiota that were lost through domestication and industrialization processes, including including the (over)use of antibiotics, pesticides, and fertilizers?

Similar to reversing industrialization-associated changes in human gut microbiota , plant microbiome rewilding builds on the premise that wild ancestors harbor microbial genera with specific traits that are not found (or are strongly depleted) in the microbiome of modern crops. To date, however, it is unknown for most plant species whether (and which) microbial genera and functions were lost during plant domestication, and to what extent rewilding can enhance the health and sustainability of modern crops. In animal systems, the effectiveness of rewilding approaches is intensely debated , and similar discussions are needed for crop rewilding approaches.

Plant domestication is one of the most important accomplishments in human history, helping drive the transition from a nomadic to a sedentary lifestyle. Through stepwise processes, crop plants acquired a suite of new traits, including larger seeds, determinate growth, photoperiod sensitivity, and reduced levels of bitter substances. Although this led to a more continuous food supply, domestication caused a reduction in plant genetic diversity because only desired alleles were spread, while genomic regions next to the target genes suffered selective sweeps (6). This so-called “domestication syndrome” decreased the ability of crops to withstand pests and diseases

The Battle for Biodiversity and Human Rights

From the lush Amazon rainforest to the frigid Arctic Ocean, the world’s landscapes — and all the wildlife they contain — are under threat, and the world needs to set aside a third of all land and sea territories to save them, U.N. experts say.

The call is central to the global agreement being hashed out in December 2022 at the U.N. biodiversity summit in Montreal. If approved, governments would be agreeing to set aside 30% of their land and sea territories for conservation by 2030 – the so-called 30-by-30 goal, doubling the amount of land area and more than tripling the ocean territory currently under conservation…

A June 2022 study in the journal Science found, however, that at least 44% of global land area would be needed to protect areas with a high diversity of species, prevent the loss of intact ecosystems, and optimize the representation of different landscapes and species. But more than 1.8 billion people live in these areas

One of the key tension points that has emerged in the 30-by-30 debate at COP15 is whether the target should be carried out globally or at a national level…It is an important distinction, scientists and negotiators said. Some countries are small, without much land to set aside for nature. Others are vast and still contain a high degree of biodiversity, such as tropical forest nations like Brazil and Indonesia. Were such countries to protect only 30% of their territories, that could actually result in a significant loss of nature…Currently, just under 50% of the Amazon is under some form of official protection or indigenous stewardship, so a national pledge to conserve 30% would represent a significant downgrade.

The other dispute plaguing 30-by-30 is over what should count as protection. Some countries might allow people to live within protected areas or promote indigenous stewardship of these lands. Some might even allow for extractive industries to operate under permits and regulation. In other cases, conservation areas are off limits to everyone. The European Union has proposed allowing activities like logging, mining and fishing to be carried out under conservation management for 20% of protected areas, while 10% would be held under stricter protections.

The idea caused environmental nonprofit Greenpeace to accused the EU last week of trying to water down language on 30-by-30, which the EU denied.

Sins of Environmentalism

During the opening ceremony of the (Conference of the Parties) COP15 of the Biodiversity Convention taking place in early December 2022,  Canadian Prime Minister Justin Trudeau called for a global agreement to protect 30% of the world’s land and water by 2030. This so-called ’30×30′ plan is opposed by a number of groups that promote the rights of indigenous peoples. According to Survival International, an organization campaigning for Indigenous rights, 30 x 30 will be the biggest land grab in history.

Already in many Protected Areas around the world local people, who have called the land home for generations, are no longer allowed to live on and use the natural environment to feed their families, gather medicinal plants or visit sacred sites.

Fortress Conservation’ is one example of a conservation model that excludes Indigenous communities. It began with the formation of Yosemite, the world’s first national park, in North America over 150 years ago.  To preserve the ‘pristine wilderness’ humans needed to be expelled so the native Americans, who had lived in and cared for the region for thousands of years, were evicted.

Only 3 per cent of the world’s land remains ecologically intact, and biodiversity loss continues at an alarming rate.  In 2010, member states of the Convention on Biological Diversity (CBD) committed to placing 17 per cent of the world’s land within protected areas by 2020. Yet during that decade global biodiversity actually declined significantly.

There have also been systemic human rights abuses. Rainforest Foundation UK protects the world’s rainforests by supporting and empowering the Indigenous people and local communities which live in them.  But its research into 34 Protected Areas in the Congo Basin showed that without the presence of Indigenous communities, animal populations dwindled, and extractive activities increased. This was despite large investments having been channeled into them.  It also uncovered widespread disregard for local communities’ rights and livelihoods and conflict between forest peoples and conservationists in this region.

According to Joe Eisen, Executive Director of Rainforest Foundation UK, human rights abuses are commonplace in the Congo Basin. “Our research has shown these human rights abuses are not just the isolated actions of rogue park rangers but are rather part of a system in which displacement, torture, gender-based violence and extrajudicial killings are used to control Indigenous peoples and other local communities who live in, and depend on, areas of high conservation value,” he says.

Protected Areas are often managed by major international conservation organizations, who employ armed guards to evict the local population and prevent their return. These actions have long-term consequences and destroy Indigenous livelihoods and cultures.

There are calls for the development of a community-based conservation model, which empowers Indigenous people, rather than removing them from their ancestral lands.

Exist, Evolve, Be Restored: the Rights of Nature

Only a few years ago, the clear, shallow waters of Mar Menor, a saltwater lagoon off eastern Spain that is Europe’s largest, hosted a robust population of the highly endangered fan mussel, a meter-long bivalve. But in 2016, a massive algal bloom, fueled by fertilizer washing off farm fields, sucked up the lagoon’s oxygen and killed 98% of the bivalves, along with seahorses, crabs, and other marine life.

The suffocating blooms struck again and again, and millions of dead fish washed onto shore. In 2021 local residents—some of whom benefit from tourism to the lagoon—had had enough. Led by a philosophy professor, activists launched a petition to adopt a new and radical legal strategy: granting the 135-square-kilometer lagoon the rights of personhood. Nearly 640,000 Spanish citizens signed it, and on 21 September, Spain’s Senate approved a bill enshrining the lagoon’s new rights. The new law doesn’t regard the lagoon and its watershed as fully human. But the ecosystem now has a legal right to exist, evolve naturally, and be restored. And like a person, it has legal guardians, including a scientific committee, which will give its defenders a new voice.

The lagoon is the first ecosystem in Europe to get such rights, but this approach to conservation has been gaining popularity around the world over the past decade…The clearest success story, scholars say, is the Whanganui River in New Zealand, which was given legal rights by an act of Parliament in 2017. Like a person, the river and its catchment can sue or be sued, enter contracts, and hold property. In that case, the aim was not to stop pollution but to incorporate the Māori connection between people and nature into Western law. “The river and the land and its people are inseparable,” Niko Tangaroa, a Māori elder of the Whanganui Iwi people and a prominent activist for the river, wrote in 1994.

What is your Extinction-Risk Footprint?

A new study quantifies how the consumption habits of people in 188 countries, through trade and supply networks, ultimately imperil more than 5,000 threatened and near-threatened terrestrial species of amphibians, mammals and birds on the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species. For the study, recently published in Scientific Reports, researchers used a metric called the extinction-risk footprint. The team found that 76 countries are net “importers” of this footprint, meaning they drive demand for products that contribute to the decline of endangered species abroad. Top among them are the U.S., Japan, France, Germany and the U.K. Another 16 countries—with Madagascar, Tanzania and Sri Lanka leading the list—are designated as net “exporters,” meaning their extinction-risk footprint is driven more by consumption habits in other countries. In the remaining 96 countries, domestic consumption is the most significant driver of extinction risk within those nations.

African trees logged in gorilla habitat, for example, could end up as flooring in Asia.  Other species highlighted in the study include the Malagasy giant jumping rat, a mammal that can jump 40 inches high and is found only in Madagascar. Demand for food and drinks in Europe contributes to 11 percent of this animal’s extinction-risk footprint through habitat loss caused by expanding agriculture. Tobacco, coffee and tea consumption in the U.S. accounts for 3 percent of the extinction-risk footprint for Honduras’s Nombre de Dios streamside frog, an amphibian that suffers from logging and deforestation related to agriculture.

Relentless Efficiency: the View of Pigs

Gestation crates for pigs are typically about two feet wide and prevent sows from turning around, maximizing use of available space. Some producers say it also prevents the pigs from harming one another. Breeding pigs can produce seven or more piglets per litter, totaling well over 60 piglets in consecutive pregnancies over a few years. Widespread use of gestation crates began in the 1970s as pork producers gave priority to efficiency. A 1978 article in the industry publication National Hog Farmer suggested producers consider the sow “a valuable piece of machinery whose function is to pump out baby pigs like a sausage machine.”

“Under that mind-set, the industry went, no pun intended, hog wild into moving pigs into gestation crates,” says Matthew Prescott, senior director of food and agriculture for the Humane Society, who has been focused on eliminating the crates since 2002.

Are We Transgressing the Planetary Boundaries?

There are an estimated 350,000 different types of manufactured chemicals on the global market. These include plastics, pesticides, industrial chemicals, chemicals in consumer products, antibiotics and other pharmaceuticals….The rate at which these pollutants are appearing in the environment far exceeds the capacity of governments to assess global and regional risks, let alone control any potential problems..

In 2009, an international team of researchers identified nine planetary boundaries that demarcate the remarkably stable state Earth has remained within for 10,000 years – since the dawn of civilization. These boundaries include greenhouse gas emissions, the ozone layer, forests, freshwater and biodiversity. The researchers quantified the boundaries that influence Earth’s stability, and concluded in 2015 that four boundaries have been breached. But the boundary for chemicals was one of two boundaries that remained unquantified.

This new research takes this a step further. The researchers say there are many ways that chemicals and plastics have negative effects on planetary health, from mining, fracking and drilling to extract raw materials to production and waste management.

Some of these pollutants can be found globally, from the Arctic to Antarctica, and can be extremely persistent…Global production and consumption of novel entities is set to continue to grow. The total mass of plastics on the planet is now over twice the mass of all living mammals, and roughly 80% of all plastics ever produced remain in the environment. Plastics contain over 10,000 other chemicals, so their environmental degradation creates new combinations of materials – and unprecedented environmental hazards. Production of plastics is set to increase and predictions indicate that the release of plastic pollution to the environment will rise too, despite huge efforts in many countries to reduce waste.

The Other Middle East Crisis: Rivers are Drying

Protests in the Iranian city of Isfahan erupted in November 2021 due to a severe shortage of water, as the region continues to suffer from a year of low rainfall and drought. Thousands of farmers and others who supported them took to the streets in Isfahan in central Iran, expressing their dissatisfaction at the water shortages and urging the government to solve the crisis. They shouted “let Isfahan breathe again, revive Zayandeh Rud,” referring to the dried river which supplies their crops with water.

The drying up of the Zayandeh Rud river has not only been caused by drought, however, but also by the government’s diversion of water from the river to supply other areas and with a pipeline supplying water to Yazd province also having been damaged. Those incidences have contributed to the farms being left dry and the famers’ livelihoods being threatened.

The water shortages and the drying of the river come at a time when the region is suffering from a similar shortage, as rainfall has been low and temperatures have increased to make it one of the hottest and driest years recorded. ..Neighboring Iraq and Syria have also been expressed concern over the shortage of water this year… In November 201, a major reservoir in Syria also dried up completely, and was similarly due to a combination of climatic and structural causes.

Re-Growing Our Lost Tropical Forests

Scientists have concluded that tropical forests demonstrate high resilience, even after they are cut down, due to agriculture or pasture use, if they are left alone for 20 years.  According to the study published in December 2021. 

“Tropical forests are converted at alarming rates to other land uses yet they also have the potential to regrow naturally on abandoned agricultural fields and pastures. Widespread land abandonment because of fertility loss, migration, or alternative livelihood options has led to a rapid increase in the extent of regrowing forests. Currently, regrowth covers as much as 28% (2.4 million km2) of the neotropics alone. Regrowing secondary forests form a large and important component of human-modified tropical landscapes and have the potential to play a key role in biodiversity conservation, climate change mitigation, and landscape restoration.

The Northern Frontier: Who’s Taking Advantage of Climate Change?

Owing to climate change…the share of boreal land that can support farming could increase from 8% to 41% in Sweden. It could increase from 51% to 83% in Finland. Efforts to farm these areas will alarm people who value boreal forests for their own sake. And cutting down such forests and ploughing up the soils that lie beneath them will release carbon. But the climatic effects are not as simple as they might seem. Northern forests absorb more heat from the sun than open farmland does, because snow-covered farmland reflects light back into space…

The fact that felling boreal forests may not worsen climate change, though, says nothing about the degree to which it could affect biodiversity, ecosystem services or the lives of forest dwellers, particularly indigenous ones.

Some governments are already keen to capitalize on climate change. Russia’s has long talked of higher temperatures as a boon. President Vladimir Putin once boasted that they would enable Russians to spend less money on fur coats and grow more grain. In 2020 a “national action plan” on climate change outlined ways in which the country could “use the advantages” of it, including expanding farming. Since 2015 Russia has become the world’s largest producer of wheat, chiefly because of higher temperatures.

Russia’s government has started leasing thousands of square kilometers of land in the country’s far east to Chinese, South Korean and Japanese investors. Much of the land, which was once unproductive, is now used to grow soybeans. Most are imported by China, helping the country reduce its reliance on imports from America. Sergey Levin, Russia’s deputy minister of agriculture, has predicted that soya exports from its far-eastern farmlands may reach $600m by 2024. That would be nearly five times what they were in 2017. The government of Newfoundland and Labrador, a province on the north-eastern tip of Canada, is also trying to promote the expansion of agriculture into lands covered by forests…

All told, the northern expansion of farmland will only go some way towards mitigating the damage climate change may do to agriculture. The societies that will benefit from it are mostly already wealthy. Poor places, which rely much more heavily on income from exporting agricultural produce, will suffer.

Keep Killing Environmental Defenders

A report released by Global Witness in September 2021 reveals that 227 land and environmental activists were murdered in 2020 for defending their land and the planet. That constitutes the highest number ever recorded for a second consecutive year…The figures show the human cost of the destruction wrought by exploitative industries and corporations. At least 30% of recorded attacks were reportedly linked to resource exploitation – across logging, hydroelectric dams and other infrastructure, mining, and large-scale agribusiness. Logging was the industry linked to the most murders with 23 cases – with attacks in Brazil, Nicaragua, Peru and the Philippines…

Colombia was once again the country with the highest recorded attacks, with 65 defenders killed in 2020. A third of these attacks targeted indigenous and afro-descendant people, and almost half were against small-scale farmers. In 2020 the disproportionate number of attacks against indigenous communities continued – with over a third of all fatal attacks targeting indigenous people. Attacks against indigenous defenders were reported in Mexico, Central and South America, the Philippines, Saudi Arabia and Indonesia. Nicaragua saw 12 killings – rising from 5 in 2019, making it the most dangerous country per capita for land and environmental defenders in 2020.

Amazon Deforestation: Putting a Number on Climate Damage

In April 2021, the Brazilian Federal Public Prosecutor’s Office filed a public civil action against a rural landowner, seeking the landowner’s accountability for alleged illegal deforestation connected to breeding cattle in the Amazon….Aside from demanding compensation for environmental damages, collective damages, as well as compensation due to the profits illegally obtained in the logging process, the prosecutor required that the defendant pay compensation for climate damages resulting from the deforestation, something until now unwitnessed in cases of this sort in Brazil. N

By employing a carbon calculator software developed by IPAM, the Amazonian Research Institute, the Prosecutor’s Office calculated how much carbon was expected to have been released into the atmosphere per hectare of deforestation in that particular area. With that information, knowing the extension of the deforestation and using the carbon pricing practiced by the Amazon Fund, the Prosecutor’s Office came to the conclusion that the defendant was liable for a BRL 44.7 million compensation for climate damages.

From Natural Landmark to an Oil Spill Wasteland

Mohammad Abubakar, Minister of Environment  disclosed in July 2021 that Nigeria recorded 4,919 oil spills between 2015 to March 2021 and lost 4.5 trillion barrels of oil to theft in four years.

Mr Abubakar disclosed this at a Town Hall meeting in Abuja, organised by the Ministry of Information and Culture, on protecting oil and gas infrastructure. “The operational maintenance is 106, while sabotage is 3,628 and yet to be determined 70, giving the total number of oil spills on the environment to 235,206 barrels of oil. This is very colossal to the environment.

“Several statistics have emphasised Nigeria as the most notorious country in the world for oil spills, loosing roughly 400,000 barrels per day. “The second country is followed by Mexico that has reported only 5,000 to 10,000 barrel only per day, thus a difference of about 3, 900 per cent.

“Attack on oil facilities has become the innovation that replaced agitations in the Niger Delta region against perceived poor governance and neglect of the area.

Save Time and Money but Destroy Soil and Oceans

The images of swaths of garbage floating on the oceans’ surface have become a rallying call to address plastic pollution, but there is more to this challenge than meets the eye. While plastics and microplastics – items smaller than 5 mm – accumulate and impact marine environments, much of the problem is rooted in land contamination. Land-based plastic pollution, which often feeds into the oceans, is estimated to be at least four times higher than what is in the oceans, according to a study published in Global Change Biology. 

“Soil is the main source of microplastics reaching oceans through soil erosion and surface runoff,”  Plastics settle in soil through disposal in landfills, as well as through the use of plastic-sheets in agriculture or application of microplastic contaminated compost. “Direct disposal of plastics to ocean is relatively less pronounced compared to the transfer of microplastics from land. Microplastics, lighter than soil particles, such as sand, silt and clay, are easily lost to waterways,”…

“We contribute to plastic pollution through indiscriminate disposal of plastics in landfills and use of microbeads in cosmetics and microfibers in textiles. There are efforts to produce biodegradable plastics, which may provide some solution to plastic pollution, but bioplastic may not be the silver bullet to manage plastic pollution.” Commonly used biodegradable bioplastics “retain their mechanical integrity under natural conditions, potentially causing physical harm if they are ingested by marine or terrestrial animals.” “The fate of biodegradable bioplastics in natural and engineered environments could be potentially problematic. Methane is a product of biodegradation in anaerobic environments in landfills.” These bioplastics, furthermore, require high temperatures, controlled aeration and humidity to degrade completely.

Due to their small size, microplastics, especially nanoplastics resulting from the degradation of microplastic, can enter organisms’ internal organs, where they could potentially transfer contaminants attached to them. These can include persistent organic pollutants, like polychlorinated biphenyls (PCBs), as well as trace metals like mercury and lead. The plastics and pollutants that accumulate on or in them enter the food chain and can eventually be transferred to humans, causing growing food safety concerns.

The Joint FAO/IAEA Centre’s laboratories are equipped to research the presence of microplastics in food. “Techniques such as energy dispersive X-ray spectroscopy and infrared and Raman spectroscopy can be applied to screen for plastics in foods, enabling risk assessment and management,” said Andrew Cannavan, Head of the Joint Centre’s Food and Environmental Protection Section.

How to Remove Carbon from 30 Million Cars Every Single Year

Gabon is the first country in Africa to receive results-based payments for reduced emissions from deforestation and forest degradation. The first payment is part of the breakthrough agreement between Gabon and the multi-donor UN-hosted Central African Forest Initiative’s (CAFI) in 2019 for a total of $150 million over ten years.

At a high-level event organised on Tuesday, Sveinung Rotevatn, Norway’s Minister of Climate and Environment said on behalf of CAFI: “This is the first time an African country has been rewarded for reducing forest-related emissions at the national level.  It is extremely important that Gabon has taken this first step. The country has demonstrated that with strong vision, dedication and drive, emissions reductions can be achieved in the Congo Basin forest.” Gabon is leading the way in maintaining its status of High Forest Cover Low Deforestation (HFLD) country. ..

Gabon has preserved much of its pristine rainforest since the early 2000s in creating 13 national parks, one of which is listed UNESCO World Heritage Site. Its forests absorb a total of 140 million tons of CO2 every year, the equivalent of removing 30 million cars from the road globally.

Gabon has also made significant advances in sustainable management of its timber resources outside the parks, with an ambition to ensure that all forest concessions are FSC-certified. Forest spans over 88% of its territory, and deforestation rates have been consistently low (less than 0.08%) since 1990. Gabon’s forests house pristine wildlife and megafauna including 60% of the remaining forest elephants, sometimes called the “architects” or “gardeners” of the forest for their roles in maintaining healthy ecosystems and recently listed as critically endangered.

Can We Change Path? Saving Forests and Cutting Carbon

No ecosystem is more important in mitigating the effects of climate change than tropical rainforest. And South-East Asia is home to the world’s third-biggest patch of it, behind the Amazon and Congo basins. Even though humans release carbon from these forests through logging, clear-felling for agriculture and other disruptions, some are so vast and fecund that the growth of the plants within them absorbs even more from the atmosphere. The Congo basin, for instance, locks up 600m tonnes of carbon a year more than it releases, according to the World Resources Institute (WRI), an international NGO that is equivalent to about a third of emissions from all American transport.

In contrast, such is the extent of clearing for plantations in South-East Asia’s rainforests, which run from Myanmar to Indonesia, that over the past 20 years they have turned from a growing carbon sink to a significant source of emissions—nearly 500m tonnes a year. Indonesia and Malaysia, home to the biggest expanses of pristine forest, have lost more than a third of it this century. Cambodia, Laos and Myanmar, relative newcomers to deforestation, are making up for lost time.

The Global Forest Watch, which uses satellite data to track tree cover, loss of virgin forest in Indonesia and Malaysia has slowed for the fourth year in row—a contrast with other parts of the world…The Leaf Coalition, backed by America, Britain and Norway, along with such corporate giants as Amazon, Airbnb, and Unilever, aims to create an international marketplace in which carbon credits can be sold for deforestation avoided. An initial $1bn has been pledged to reward countries for protecting forests. South-East Asia could be a big beneficiary,

Admittedly, curbing deforestation has been a cherished but elusive goal of climate campaigners for ages. A big un initiative to that end, called REDD+, was launched a decade ago, with Indonesia notably due for help. It never achieved its potential. Projects for conservation must jump through many hoops before approval. The risk is often that a patch of forest here may be preserved at the expense of another patch there. Projects are hard to monitor. The price set for carbon under the scheme, $5 a tonne, has been too low to overcome these hurdles.

The Leaf Initiative would double the price of carbon, making conservation more attractive. Whereas buyers of carbon credits under REDD+ pocketed profits from a rise in carbon prices, windfalls will now go to the country that sold the credits. Standards of monitoring are much improved. Crucially, the scheme will involve bigger units of land than previous efforts, the so-called jurisdictional approach. That reduces the risk of deforestation simply being displaced from a protected patch to an unprotected one.

Addicted to Weather Modification: Make it Rain Now

Attempts to modify the weather can be dangerous. They require pilots to head into the kind of clouds they would normally avoid. But officials claim that China’s efforts to trigger or boost precipitation by scattering chemicals in the sky, which began in the 1950s, have been hugely successful. Today the country spends at least $200m a year on the programme. In 2018 about 50,000 people were involved in it, most of them part-time or seasonal staff working from small offices in rural areas.

Among the 50 or so countries where cloud-seeding is practiced, China is the most enthusiastic promoter of it….Officials claim it can help to put out wildfires and reduce air pollution. State media report that cloud-seeding brings down about 50bn cubic metres of extra rain or snow across the country each year—equal to about 8% of total water demand. Officials in Beijing claim that in the parched capital, seeding can boost rainfall by 15%…

Recent advances in radar and computer modelling have made rigorous tests more possible. Scientists now generally agree that cloud-seeding can slightly augment snowfall from specific types of cloud that form on the slopes of mountains. Some of China’s weather-modification projects take place in such environments. But elsewhere, despite the lack of convincing proof that it works, farmers still want the government to try. And the government likes getting credit when rain does fall. Cloud-seeding creates employment in poor rural places, in particular for army veterans who believe that the government owes them a job.

Only a few of China’s rainmakers use planes. More commonly, they fire silver iodide into the sky from artillery pieces. But that can be dangerous, too. Locals are often advised to keep an eye out for unexploded shells, which occasionally land on people’s homes….

Nuking Tahiti: the Moruroa Files

From 1966 to 1974, France blew up 41 nuclear weapons in above-ground tests in French Polynesia, the collection of 118 islands and atolls that is part of France. The French government has long contended that the testing was done safely. But a new analysis of hundreds of documents declassified in 2013 suggests the tests exposed 90% of the 125,000 people living in French Polynesia to radioactive fallout—roughly 10

The findings come from a 2-year collaboration, dubbed the Moruroa Files, between Disclose, a French nonprofit that supports investigative journalism; Interprt, a collective of researchers, architects, and spatial designers affiliated with the Norwegian University of Science and Technology who focus on environmental issues; and the Science & Global Security program at Princeton. The findings were presented on 9 March on the project’s website, in a book, and in a technical paper posted to the arXiv preprint server.

The abandoned testing facility at the Moruroa Atoll. The atoll is at the risk of collapsing due to nuclear blasts

Declassified documents suggest actual exposures were between two and 20 times higher than France’s Atomic Energy Commission (CEA) estimates… Reasons for the discrepancies vary from test to test, he says. For example, CEA acknowledged that the first test, dubbed Aldébaran, exposed residents of the Gambier Islands to relatively high levels of fallout. But actual exposures were likely higher still… Although CEA noted that contaminated rainwater fell on the island, he says, it failed to consider that many residents likely drank the contaminated water, collected in household cisterns, for days.

Most important, the documents suggest a single test in 1974, called Centaure, exposed the entire population of Tahiti—87,500 people at the time—to fallout. French authorities set off a relatively tiny atom bomb with an explosive yield equal to 4 kilotons of TNT, and weather forecasts predicted that winds should carry fallout to the north. Instead, the wind blew to the west, carrying the plume directly over Tahiti. A new simulation based on data in the documents shows how the plume of radiation wafted over the island. CEA estimated that people on the island received a dose of about 0.6 mSv.  However, Phillipe and colleagues argue that CEA underestimated the total amount of radiation that accumulated on the ground over several days, didn’t account for radiation lingering in vegetables consumed later…

The new analysis moves the vast majority of French Polynesians past the exposure threshold to qualify for compensation. Philippe and Schoenberger would like to see France do away with the exposure standard and compensate anyone who lived through the tests and developed a qualifying cancer. “Our hope is to demonstrate that this kind of threshold can be prejudicial to claimants just because of the difficulties of proving exposure,” Schoenberger says.

Philippe estimates that, assuming a cancer rate of 0.2% per year, roughly 10,000 cancer patients or their families would qualify retroactively and that compensating them would cost about €700 million. Future cancers would cost about €24 million per year, he estimates. However, Hughes says it remains to be seen whether the French government will even acknowledge the analysis. “My fear is that they will simply ignore it,” Hughes says.

The declassified documents also show the French government routinely failed to warn Polynesians about the radiation risks, Philippe says. In the Centaure test, authorities could have warned Tahitians about the approaching fallout 2 days in advance, but did not. Ironically, Philippe notes, the United States, the Soviet Union, and other countries were monitoring the tests remotely. “Everybody knew what was going on,” he says, “except the Polynesians.”

The Horrors of Bombing: 50 Years After

 In Cambodia, however, fertile land often signifies danger rather than abundance. When America dropped an estimated 1.8m tonnes of explosives on the country during the Vietnam war, those falling on hard ground generally detonated, whereas many landing on softer earth did not. No one knows how many bombs remain in rich soil. But a paper by four academics at Ohio State University who studied satellite images and reports by landmine-removal groups from a single village, found that perhaps half of the munitions have not exploded.

These wartime remnants have given the United States’ bombing campaign of 1965-73—which ostensibly targeted Viet Cong supply lines, but caused perhaps 150,000 deaths—an enduringly lethal legacy. Since 1979, unexploded ordnance has killed at least 19,000 people in Cambodia (though some may have been blown up by landmines from subsequent wars, rather than by American bombs). Cambodia now has the world’s highest rate of amputees.

A recent study by Erin Lin shows that America’s bombardment injured not just Cambodia’s people but its economy as well. She first interviewed farmers in the country, who said they thought that richer, darker soil presented an unusually high risk of hidden ordnance—especially in heavily bombed areas. They work in constant fear of explosions. Some said that they only planted crops in parts of their farms that they were confident contained no bombs, or that they used hand tools instead of machines to reduce the risk of detonation.

The Fukushima Nuclear Meltdown: Ten Years — and Counting

A resolution to the crisis at the Fukushima Daiichi nuclear power plant remains a distant goal a decade after three of its reactors melted down. The most challenging part of the cleanup—removing molten nuclear fuel from each reactor—has yet to begin because of high radiation inside the reactor buildings, putting the targeted decommissioning of the plant by 2051 into doubt.

More than 80% of the Japanese public doesn’t feel significant progress is being made and is concerned about further accidents because of recent events. On Feb. 13, 2021 a large earthquake centered near Fukushima, an aftershock of the one 10 years ago, caused water to slosh out of a tank containing spent fuel rods, which must be kept submerged to avoid overheating. A week later, a fish caught off the coast of Fukushima was found to contain 10 times the allowed level of radioactive cesium…This incident shows how risks from the plant continue to weigh on those who live and work nearby. 

“We are still struggling with harmful rumors from the nuclear plant accident,” said Tadaaki Sawada, a spokesman for the federation of Fukushima fishery cooperatives. “How many more years will it continue?”…By several measures, the worst nuclear disaster since the Chernobyl accident in 1986 has been contained. Only around 2% of Fukushima prefecture, or state, is still a no-go area, down from 12% immediately after the disaster. An extensive decontamination process removed topsoil from areas around the plant. Still, thousands of people remain forced out of towns closest to the plant.

In 2020, plant operator Tokyo Electric Power Co., known as Tepco, and the government were close to a decision to start releasing into the sea over a million cubic meters of water from the plant, but plans were suspended amid opposition from local fishermen and concerns raised by neighboring countries. Contaminated rain and groundwater is stored in large tanks that dominate one side of the plant site. Once treated to remove most radioactive elements, the water still contains tritium, a form of hydrogen that emits a weak form of radiation. Tritium is regularly released into the sea and air from nuclear plants around the world after dilution.

Inspectors from the International Atomic Energy Agency visited the Fukushima plant in 2020 and said disposal of the treated water into the sea would be in line with international practice. “A decision on the disposition path should be taken urgently” to keep the overall decommissioning on track, the IAEA said.

The most challenging part of the cleanup—removing molten nuclear fuel from each reactor—has yet to begin…Tepco has yet to get a clear picture of the location of molten fuel in the reactors because the levels of radiation are damaging even to robots…Gov. Uchibori said that gaining an accurate grasp of the molten-fuel situation was critical to making headway. “If you look at the entire process, right now we are still around the starting point of decommissioning,” he said.

The Fake Green Labels Lulling Our Conscience

Certification is a verification process through which an owner of a farm, a fishery or a forest can indicate they comply with social or environmental standards, and earn the right to sell their products as certified. Certified products often include consumer-facing ecolabels. Companies producing or trading “forest and ecosystem-risk commodities” often rely on certification to reassure customers. They want to show that they or their suppliers have taken action to minimize the negative environmental and social impacts linked to production, so their products can be considered ‘sustainable’.

According to a Greenpeace report, while some certification schemes have strong standards, weak implementation combined with a lack of transparency and product traceability means even these schemes have major failings. Too many certified companies continue to be linked to forest and ecosystem destruction, land disputes and human rights abuses. Currently, certification enables destructive businesses to continue operating as usual. By improving the image of forest and ecosystem risk commodities and so stimulating demand, certification risks actually increasing the harm caused by the expansion of commodity production. Certification schemes thus end up greenwashing products linked to deforestation, ecosystem destruction and rights abuses.

Planting Trees Can be Bad for the Planet

Some scientists argue that deforestation is not always harmful for the planet. Christopher A. Williams, a professor at Clark University’s Graduate School of Geography (Worcester, Massachusetts), says that instead of warming up the Earth, deforestation can actually cool it down. (See Climate impacts of U.S. forest loss span net warming to net cooling, Feb. 2021) But some experts are concerned that Williams’ work is likely to be misconstrued as permission to continue deforesting, which is not his intention.

It’s widely accepted that our existing forests are vital carbon sinks, and the best course of action is to stop deforestation, while rewilding and reforesting areas already lost. Deforestation contributes to climate change, can cause wildfires, desertification, soil erosion and most of all – releases huge amounts of carbon dioxide which causes global warming.

While the above may be true, Williams’ new research argues that there are two factors we are not acknowledging: the significance of location and something known as ‘the albedo effect’. Put simply, ‘the albedo effect’ is the process in which forests retain heat. Forests tend to be darker than other surfaces, which means they absorb more sunlight and hold onto heat, explains Williams. As a result, some scientists believe that deforestation gets rid of unwanted heat which is contributing to global warming.

“We found that in some parts of the country like the Intermountain West, more forest actually leads to a hotter planet when we consider the full climate impacts from both carbon and albedo effects,” says Professor Williams. He adds that it is important to consider the albedo effect of forests alongside their well-known carbon storage when aiming to cool the planet.

The team discovered that for approximately one quarter of the US, forest loss causes a persistent net cooling because the albedo effect outweighs the carbon effect.  “It is all about putting the right trees in the right place,” explains Williams, “and studies like ours can help identify where the potential for cooling is greatest.”

For instance, loss of forests east of the Mississippi River caused planetary warming, while forest loss in the Intermountain and Rocky Mountain West led to a net cooling. “If we fail to consider both the carbon and the albedo effects, large-scale tree-planting initiatives, such as Canada’s 2Billion Trees Initiative and The Nature Conservancy’s Plant a Billion Trees campaign, could end up placing trees in locations that are counterproductive for cooling the climate system,” he says.

How Soil Can Fight Pollution

Soil biodiversity is essential for most of the ecosystem services and functions that soils
provide and perform. Soil microbes (i.e., bacteria, fungi) and microfauna (i.e., protozoa
and nematodes) transform organic and inorganic compounds into available forms. These transformations are critical for nutrient cycling and availability, for plants, and other species growth, for cycling of soil organic matter and carbon sequestration, and for the filtration, degradation, and immobilization of contaminants in water and soil.

An important part of the food web is represented by mesofauna, such as springtails and mites, which accelerate litter decomposition and enhance nutrient cycling and availability (especially nitrogen), and predators of smaller soil organisms.

Soil macro, and megafauna such as earthworms, ants, termites, and some mammals act as ecosystem engineers that modify soil porosity, water and gas transport, and bind soil particles together into stable aggregates that hold the soil in place and thus reduce erosion.

Soil biodiversity can mitigate threats to ecosystem services, for instance by acting as a powerful tool in bioremediation of contaminated soils. Biostimulation and bioaugmentation are environmentally sound strategies that contribute to the filtration, degradation, and immobilization of target contaminants. Furthermore, the integral use of organisms such as microbes (bioaugmentation), plants (phytoremediation) and earthworms (vermiremediation) as a bioremediation strategy in hydrocarbon-contaminated soils has proven to be a viable alternative for increasing hydrocarbon removal. On the other hand, soil macrofauna, such as earthworms, termites, and ants, play an important role in improving soil structure and aggregation, which can improve resistance to soil erosion caused by wind and water.

The Great Green Wall and its Past Mistakes

The Great Green Wall  aims to transform the lives of some 100 million people by planting a mosaic of trees, shrubs, and grasses along a corridor stretching some 8000 kilometers across Africa by 2030. Since the African Union first launched the Great Green Wall in 2007, the initiative has struggled to make headway. Made up of local efforts across 11 countries, it has reached just 16% of its overall goal to vegetate 150 million hectares.

But in January 2021, the project—which analysts estimate will cost at least $30 billion—got a major boost: a pledge of $14 billion in funding over the next 5 years from a coalition of international development banks and governments. The money is meant to accelerate the effort to sustain livelihoods, conserve biodiversity, and combat desertification and climate change, French President Emmanuel Macron said in announcing the pledges on January 11, 2021.

Environmental restoration and community development specialists welcomed the news. But many are also apprehensive. In recent years, research by ecologists, economists, and social scientists has shown that many forestry projects around the world have failed because they didn’t adequately address fundamental social and ecological issues…Many efforts, particularly those not led by local communities, stumble. Newly planted trees can die of neglect when planners don’t engage communities from the start in discussions about which species to plant, as well as whether residents are willing and able to provide the water, fertilizer, and protection from grazing animals that saplings need. Farmers are often busy and have their own priorities; they “will not … manage trees that they do not value.” …

Elvis Paul Tangem, who coordinates the Great Green Wall Initiative for the African Union Commission, agrees. He says promises to plant huge numbers of trees at low cost, for example at $1 per seedling, can distract from the real challenge. “You can plant a tree for $1,” he says, “but you cannot grow a tree for $1.”

How to Find the True Cost of Water

At current rates of consumption, the demand for water worldwide will be 40% greater than its supply by 2030, according to the UN. Portfolio managers are realizing that physical, reputational and regulatory water risk could hurt their investments, particularly in thirsty industries such as food, mining, textiles and utilities.

One worry is that shocks to supply could drown or dry out a company’s assets. In recent years Coca-Cola has been forced to close plants in India because of drought. In 2019 floods in America’s Midwest caused disruptions at the facilities of two food giants, Cargill and Tyson Foods. A survey by CDP, a non-profit firm, found that 783 big listed companies had faced a total of $40bn of water-related losses in 2018.

Another concern is that the price a company pays for water could rocket. The market price of water does not reflect the environmental and social costs of using it. Government subsidies also mean that companies often do not pay for its true cost. As aquifers are depleted, though, subsidies could become more costly and unpopular, forcing governments to retract them. S&P Global Trucost, a data provider, reckons that if Fortune 500 companies paid the true cost of water, based on estimates of scarcity, rather than current prices, their profit margins would shrink by a tenth. Margins for food, drink and tobacco firms would fall by three-quarters.

Disclosures of water risk are even patchier than those of greenhouse-gas emissions…Established names like Bloomberg and S&P Global are plugging the gap, as are startups. The result is that investors can approach management armed with data rather than questions. “We are getting rid of the black box that companies hide in.” 

Ceres, a non-profit firm, scores businesses on everything from direct water management to risks in the supply chain. Those seeking more detail can use visual tools, such as Bloomberg’s “maps” function, which plots a company’s facilities over a heat map based on water stress. (California is the same color as swathes of sub-Saharan Africa; far-eastern Russia looks a lot like western Europe.) Firms like Aquantix go further, and try to predict the financial cost of water risk.

The accuracy of such forecasts is not yet proven. For Andrew Mason of Aberdeen Standard Investments, though, they are still useful. They show companies that investors care about water risk and encourage them to share data. “This is where carbon was ten or 15 years ago,” he says.

Surveillance for Conservation: the Smart Wildlife Parks in Africa

In 2010, Rwanda’s government partnered with international conservation group African Parks to manage the Akagera Park…African Parks, based in South Africa, is known for reviving troubled national parks. The nonprofit worked to strengthen Akagera’s security, brought in anti-poaching dogs, purchased better field equipment, and hired and trained more rangers. The number of patrols increased from about 1,500 in 2011 to more than 5,400 last year.

Since 2013, poaching has dropped dramatically, which led to a wildlife revival that once seemed inconceivable. In 2017 Akagera reintroduced 18 black rhinos from South Africa. In a conservation milestone, the first rhino calves were born in the park a year later. As for lions, seven were reintroduced to the park in 2015. Today there are at least 35 of them prowling Akagera’s highlands, grassy plains, and forests…The Howard Buffett Foundation even donated a helicopter to the Rwandan government for rhino patrols.

Fences, more patrols, and reintroductions are all part of the park-rehabilitation playbook, but Akagera is also using a distinctive new technology to help even the odds against poachers. In 2017, Akagera became the world’s first “Smart Park” when it tested and installed a telecommunications network called LoRaWAN, or Long Range Wide-Area Network for securely tracking and monitoring just about anything in the park. Poachers can potentially intercept the conventional radio signals parks use to track animals but the low-bandwidth LoRa signals are relayed on a private, closed network on various frequencies, making them harder to crack. The network also runs on solar energy and is cheaper than satellite tracking technology.

Akagera partnered with Dutch conservation technology group Smart Parks to install LoRa receivers on towers throughout the park. (Smart Parks is the result of a merger between the Shadow View Foundation and the Internet of Life.) LoRa sensors, which vary in size and can be small enough to fit in one’s hand, can then communicate with towers to track the location of rangers, vehicles, equipment, and more. In 2017 they collected more than 140,000 location updates per day. Next year the park plans to install 100 sensors to monitor tourist vehicles as well, says Hall.

To Steal To Survive: the Illegal Lumberjacks of the Amazon

The Amata logging company was supposed to represent an answer to the thorny problem of how countries like Brazil can take advantage of the Amazon rainforest without widespread deforestation.  But after spending tens of millions of dollars since 2010 to run a 178-square-mile concession in the rainforest to produce timber sustainably, Amata pulled out in April 2020. The reason: uncontrolled wildcat loggers who invaded Amata’s land, illegally toppling and stealing trees.

Amata’s executives in São Paulo said that instead of promoting and protecting legal businesses, Mr. Bolsonaro’s administration did next to nothing to control the illegal loggers who invaded the concession in the western state of Rondônia. “It’s a conflict area,” Amata Chief Executive Ana Bastos said of the land granted to the company. “Those lumberjacks steal our lumber to survive. If we try to stop them, they will fight back. It will be an eternal conflict.”

Since they pay no taxes and make no effort to protect certain species or invest in restoration, illegal loggers can charge $431 per square meter of lumber, compared with $1,511 per square meter of legally logged timber, concession operators said.  “It is like having a regular, taxpaying shop competing with lots of tax-free peddlers right in front of your door,” said Jonas Perutti, owner of Lumbering Industrial Madeflona Ltda., which also operates concessions in the Amazon…

“The organized crime that funds illegal activity in the Amazon—including deforestation, land grabbing, lumber theft and mining—remains strong and active,” said Carlos Nobre, a Brazilian climate scientist. “It seems [the criminals] aren’t frightened by the government’s zero-tolerance rhetoric or don’t believe it’s serious.”…

Wildcat loggers are among the Amazon’s poorest residents, and many feel they have an ally in Mr. Bolsonaro,[Brazil’s President]…“There’s much corruption in law enforcement, and consumers don’t care if the wood they are buying is legal or not,” said Oberdan Perondi, a co-owner of a concession that is five times as large as Amata’s and also competes with illegal loggers.

Modern Slavery and the Collapse of Fisheries

Illegal, unreported and unregulated fishing accounts for a staggering 20-50% of the global catch. It is one reason fish stocks are plummeting: just a fifth of commercial species are sustainably fished. Illegal operators rob mostly poor coastal states of over $20bn a year and threaten the livelihoods of millions of small fishermen. A huge amount of illicit fishing happens on licensed boats, too. They might catch more than their quota, or falsely declare their catch as abundant albacore tuna instead of the more valuable bigeye. In port fisheries inspectors are always overstretched. If an operator is caught, for instance, fishing with too fine a net, the fine and confiscation are seen as a cost of doing business. Many pay up and head straight back out to sea.

The damage from illicit fishing goes well beyond fish stocks. Operators committing one kind of crime are likely to be committing others, too—cutting the fins off sharks, or even running guns or drugs. Many are also abusing their crews… A lot of them are in debt bondage…. Unscrupulous captains buy and sell these men and boys like chattel

Too often, the ultimate beneficiaries of this trade are hard to hook because they hide behind brass-plate companies and murky joint ventures. Pursuing them requires the same kind of sleuthing involved in busting criminal syndicates. An initiative led by Norway to go after transnational-fisheries crime is gaining support. Much more cross-border co-operation is needed.

At sea, technology can help. Electronic monitoring promises a technological revolution on board—Australian and American fleets are leading the way. Cameras combined with machine learning can spot suspicious behavior and even identify illicit species being brought on board…. Equally, national regulators should set basic labor standards at sea. If countries fail to follow the rules, coastal states should bar their fishing fleets from their waters. Fish-eating nations should allow imports only from responsible fleets.

Above all, governments should agree at the World Trade Organization to scrap the subsidies that promote overfishing. Of the $35bn a year lavished on the industry, about $22bn helps destroy fish stocks, mainly by making fuel too cheap. Do away with subsidies and forced labor, and half of high-seas fishing would no longer be profitable. Nor would that of China’s environmentally devastating bottom-trawling off the west African coast.

Just Forbid It – Fishing: Fishing and Marine Protected Areas

Fish, whether wild caught or farmed, now make up nearly a fifth of the animal protein that human beings eat….In this context, running the world’s fisheries efficiently might seem a sensible idea. In practice, that rarely happens. Even well-governed coastal countries often pander to their fishing lobbies by setting quotas which give little respite to battered piscine populations. Those with weak or corrupt governments may not even bother with this. Deals abound that permit outsiders legal but often badly monitored access to such countries’ waters. And many rogue vessels simply enter other people’s fishing grounds and steal their contents.

There may be a way to improve the supply side: increase the area where fishing is forbidden altogether.  This paradoxical approach, which involves the creation of so-called marine protected areas (MPAs), has already been demonstrated on several occasions to work locally. A new study “A global network of marine protected areas for food “in the Proceedings of the National Academy of Sciences…explores the idea of extending MPAs elsewhere. If the right extensions are picked designating a mere 5% more of the world’s oceans as MPAs—which would triple the area protected—could increase the future global catch of the 811 species they looked at by more than 20%. That corresponds to an extra 10m tonnes of food a year.

The idea that restricting fishing would permit more fish to be caught may seem counterintuitive, but the logic is simple. Fish in MPAs can grow larger than those at constant risk of being pulled from the ocean. Larger fish produce more eggs. More eggs mean more fry. Many of these youngsters then grow up and move out of the safe zone, thus becoming available to catch in adjoining areas where fishing is permitted…

MPAs are especially beneficial for the worst-managed areas, most of which are tropical—and in particular for overfished species…They also have the virtue of simplicity. The setting of quotas is open to pressure to overestimate of how many fish can safely be caught…This is difficult enough for countries with well-developed fisheries-research establishments. For those without such it is little more than guesswork…Setting the rules for an MPA is, by contrast, easy. You stick up a metaphorical sign that says, “No fishing”. Knowing who is breaking the rules is easy, too. If your gear is in the water, you are fishing illegally.

The Industrial Chicken and the US-China Rivalry

Animal diseases, the US-China trade war and covid-19 have all disrupted, or threatened to disrupt, industrial chicken supplies and supply chains…The unsentimental logic of high-performance poultry-rearing is easy to grasp. “White-feather meat chickens”, as they are known in China, grow to 2.5kg in 40 days. Homegrown varieties of “yellow-feather chicken”, descended from backyard fowl, take twice as long to mature and will only ever weigh half as much…

Half a century ago meat in China was a rare luxury. Now, many see it as a daily necessity. In the meantime, the country’s supplies of farmland and clean water have not grown. Agriculture remains blighted by food-safety scandals, the rampant use of fake or illegal animal medicines, and disease outbreaks. Small surprise, then, that Chinese leaders give frequent speeches about food security. A puzzle lurks, though. Leaders also call for self-reliance in key technologies. And in the case of broiler chickens, those two ambitions—rearing meat efficiently and avoiding dependence on imports—are in tension.

The chicken imported into China are the fifth-generation descendants of pedigree birds whose bloodlines represent 80 years of selection for such traits as efficient food-to-meat conversion, rapid growth, strong leg bones and disease resistance. After waves of consolidation, the industry is dominated by two firms, Aviagen (based in Alabama and owned by the ew Group of Germany) and Cobb (owned by Tyson, an American poultry giant).

The most valuable pedigree birds never leave maximum-security farms in America and Britain: a single pedigree hen may generate 4m direct descendants. Their second-generation offspring are flown to breeding sites dispersed between such places as Brazil, Britain and New Zealand, in part to hedge against supply shocks when avian influenzas and other diseases close borders. Day-old third-generation chicks are air-freighted to Jinghai Poultry, a company in China, and other places, which spend six months growing them and breeding them in climate-controlled, artificially lit indoor facilities. In all, China imports 1.6m third-generation white-feather chicks a year.

Jinghai  Poultry hatches 8m fourth-generation, “parent stock” chickens annually. The company sells some to other agri-businesses. It breeds from the rest to produce fifth-generation chicks. These are “meat chickens”, consumed in fast-food outlets, schools and factory canteens, or as chicken parts sold in supermarkets. Yellow-feather chickens, deemed tastier by Chinese cooks, account for most whole birds sold in markets.

Chinese breeders have long tried to create local varieties with bloodlines available in-country… In September 2019, the State Council, China’s cabinet, issued a paper on livestock-rearing that set self-sufficiency in poultry as a goal, calling meat-chicken breeding a priority. Big foreign firms have resisted appeals from officials to send second-generation stock to China….Dependence on foreign bloodlines does carry risks. For several months recently New Zealand was one of the only countries able to send third-generation chicks to China, after other exporters suffered bird-flu outbreaks.

Li Jinghui, president of the China Broiler Alliance, an industry association, calls conditions ripe for China’s “brilliant” scientists to develop local birds… But to develop a domestic breed from scratch would take years, and if it does not meet market needs, a firm could spend a fortune “without much to show for it”…Without a stronger animal-health system and environmental controls, biotechnology alone cannot help China to develop world-class agriculture. Moreover, a long-standing Chinese strategy—bullying foreign firms to hand over intellectual property—is counter-productive now.

The Green Climate Fund and COVID-19

 The Green Climate Fund has promised developing nations it will ramp up efforts to help them tackle climate challenges as they strive to recover from the coronavirus pandemic, approving $879 million in backing for 15 new projects around the world…The Green Climate Fund (GCF) was set up under U.N. climate talks in 2010 to help developing nations tackle global warming, and started allocating money in 2015….

Small island states have criticised the pace and size of GCF assistance…Fiji’s U.N. Ambassador Satyendra Prasad said COVID-19 risked worsening the already high debt burden of small island nations, as tourism dived…The GCF  approved in August 2020 three new projects for island nations, including strengthening buildings to withstand hurricanes in Antigua and Barbuda, and installing solar power systems on farmland on Fiji’s Ovalau island.

It also gave the green light to payments rewarding reductions in deforestation in Colombia and Indonesia between 2014 and 2016. But more than 80 green groups opposed such funding. They said deforestation had since spiked and countries should not be rewarded for “paper reductions” in carbon emissions calculated from favourable baselines…. [T]he fund should take a hard look at whether the forest emission reductions it is paying for would be permanent.  It should also ensure the funding protects and benefits forest communities and indigenous people…

Other new projects included one for zero-deforestation cocoa production in Ivory Coast, providing rural villages in Senegal and Afghanistan with solar mini-grids, and conserving biodiversity on Indian Ocean islands.  The fund said initiatives like these would create jobs and support a green recovery from the coronavirus crisis.

Forest Infernos and Food Self-Sufficiency

The Mega-Rice Project (MRP) — the conversion of 10,000 square km of peat forest into rice paddies — that was adopted in Indonesia in 1997, was a mega-failure. It produced hardly any rice because the peaty soil lacks the requisite minerals. Instead of spurring farming, the draining of the waterlogged forest with a 6,000km network of canals fuelled fire…. It was the biggest environmental disaster in Indonesia’s history.  Burning peat in 1997 on Kalimantan and the nearby island of Sumatra generated the equivalent of 13-40% of the average annual global emissions from fossil fuels. The MRP was abandoned in 1999 but its legacy endures in the infernos that have ravaged Kalimantan almost every year since.

As work begins in 2020 on the new plantation, is history poised to repeat itself? The government says it has learned from the past. Nazir Foead of the Peatland Restoration Agency says that tractors will steer clear of what remains of Central Kalimantan’s pristine peatlands…but the rest is covered in “shallow peat”, no more than 50cm deep, and so can be cultivated without cataclysm, he says.  Environmentalists are not convinced… Smouldering swamps belch vast amounts of carbon. In 2019, the fires that swept Indonesia emitted 22% more carbon than the conflagration in the Amazon rainforest did. 

But the government argues it must go ahead with the plantation, and quickly, in case covid-19 brings about food shortages… For decades the political elites “have been chasing this ideal of food self-sufficiency”, says Jenny Goldstein of Cornell University. Prabowo Subianto, the defence minister, is one of its greatest champions.

How to Poison a Population: War and Persistent Oil Pollution

Oil pollution in Syria has been a growing concern since the 2011 onset of a civil war that has taken a toll on oil infrastructure and seen rival powers compete over control of key hydrocarbon fields. In the Kurdish-held northeast, a large storage facility in the Rmeilan oil field in Hasakeh province is of particular concern, according to the Dutch peace organisation PAX. [A River of Death, pdf] Oil leaks from the Gir Zero storage facility have been suspected since at least 2014, the latest in March 2020, it said in a June report. Thousands of barrels have leaked out into creeks in the area over the past five years, threatening the health and livelihoods of people in dozens of villages….

The major Rmeilan field controlled by the Kurdish administration, located near a US airbase, has been among the Syrian Kurds’ most prized assets since regime forces withdrew early on in the war. But oil wealth comes at a heavy cost for livestock farmers
whose sheep and cows have died because they drank oil contaminated water.

Residents too suffer heavily from the pollution because  of the foul odour of gas and crude oil wafting over the area… Compounding the situation, makeshift oil refineries have cropped up across the northeast in recent years, dumping oil waste in the waterways…These informal refineries receive oil from nearby fields and process it to provide benzine, gasoline and diesel to locals.

Water Conflicts: Who Owns the Nile River

The Grand Ethiopian Renaissance Dam is a giant edifice that would span the Blue Nile, the main tributary of the Nile river.  Half a century in the making, the hydro-electric dam is Africa’s largest, with a reservoir able to hold 74bn cubic metres of water, more than the volume of the entire Blue Nile. Once filled it should produce 6,000 megawatts of electricity, double Ethiopia’s current power supply. Millions of people could be connected to the grid for the first time. More than an engineering project, it is a source of national pride.

For Egypt, however, it seems a source of national danger. Over 90% of the country’s 100m people live along the Nile or in its vast delta. The river, long seen as an Egyptian birthright, supplies most of their water. They fear the dam will choke it off. Pro-regime pundits, not known for their subtlety, have urged the army to blow it up….Ethiopia wants to start filling the reservoir during this summer’s rainy season. On June 26th, 2020 after another round of talks, Egypt, Ethiopia and Sudan pledged to reach a deal within two weeks. Ethiopia agreed not to start filling the dam during that period.

Diplomats say most of the issues are resolved. But the outstanding one is big: how to handle a drought. Egypt wants Ethiopia to promise to release certain amounts of water to top up the Nile. But Ethiopia is loth to “owe” water to downstream countries or to drain the reservoir so much that electric output suffers. It wants a broader deal between all riparian states, including those on the White Nile, which flows out of Lake Victoria down through Uganda and Sudan.

Even if talks fail and Ethiopia starts filling without a deal, Egyptians will not find their taps dry. There is enough water in the reservoir behind Egypt’s Aswan High Dam to make up for any shortfall this year. But the mood in both countries is toxic. Egyptians have cast Ethiopia as a thief bent on drying up their country. In Ethiopia, meanwhile, Egypt is portrayed as a neocolonial power trampling on national sovereignty. The outcome of the talks will have political consequences in both countries, and perhaps push them to the brink of conflict—at a time when Egypt is already contemplating involvement in a war in Libya.

Ethiopia’s grand dam became a reality and a national obsession under Meles Zenawi, the longtime prime minister who ruled until 2012. His political masterstroke was asking Ethiopians to finance it through donations and the purchase of low-denomination bonds…. Most contributed voluntarily, but there was always an element of coercion. Civil servants had to donate a month’s salary at the start. Local banks and other businesses were expected to buy bonds worth millions of birr. ….

The $4 Trillion Blackmail: The Amazon is Ours not Brazil’s

More than two dozen financial institutions around the world are demanding the Brazilian government rein in surging deforestation, which they said has created “widespread uncertainty about the conditions for investing in or providing financial services to Brazil”. The call for action, delivered in a letter to the Brazilian government on June 23, 2020, comes as concerns grow that investors may begin to divest from Latin America’s largest economy if Jair Bolsonaro’s administration fails to curb environmental destruction. “As financial institutions, who have a fiduciary duty to act in the best long-term interests of our beneficiaries, we recognise the crucial role that tropical forests play in tackling climate change, protecting biodiversity and ensuring ecosystem services,” said the letter, signed by 29 financial institutions managing more than $3.7tn in total assets.

“Considering increasing deforestation rates in Brazil, we are concerned that companies exposed to potential deforestation in their Brazilian operations and supply chains will face increasing difficulty accessing international markets. Brazilian sovereign bonds are also likely to be deemed high risk if deforestation continues.” Deforestation in the Amazon rainforest has surged in Brazil since the election of Mr Bolsonaro, a rightwing former army captain, who supports opening the protected lands to commercial activity. In the first four months of 2020, an area twice the size of New York City was razed as illegal loggers and wildcat gold miners

Investors said they are particularly concerned about Brazil’s meatpacking industry, which risks being shut out of international markets over its alleged role in deforestation. Brazil’s JBS has been repeatedly accused by environmentalists of buying cows from deforested lands in the Amazon. In May 2020 more than 40 European companies, including Tesco and Marks and Spencer, warned they would boycott Brazilian products if the government did not act on deforestation.

Amazon Rainforest: Source of Food for Vegans, Meat-Lovers

In the first four months of 2020 an estimated 1,202 square km (464 square miles) were cleared in the Brazilian Amazon, 55% more than during the same period in 2019, which was the worst year in a decade…Less attention has been paid to the role of big firms like JBS and Cargill, global intermediaries for beef and soya, the commodities that drive deforestation.  The companies do not chop down trees themselves. Rather, they are middlemen in complex supply chains that deal in soya and beef produced on deforested land. The process begins when speculators, who tend to operate outside the law, buy or seize land, sell the timber, graze cattle on it for several years and then sell it to a soya farmer. Land in the Amazon is five to ten times more valuable once it is deforested, says Daniel Nepstad, an ecologist. Not chopping down trees would have a large opportunity cost. In 2009 Mr Nepstad estimated that cost (in terms of forgone beef and soy output) would be $275bn over 30 years, about 16% of that year’s GDP.

Under pressure from public opinion, the big firms have made attempts to control the problem. In 2009, a damning report from Greenpeace led JBS, Marfrig and Minerva, meat giants which together handle two-thirds of Brazil’s exports, to pledge to stop buying from suppliers that deforest illegally. (The forest code allows owners to clear 20% of their land.) JBS, which sources from an area in the Amazon larger than Germany, says it has blocked 9,000 suppliers, using satellites to detect clearing.

The problem is especially acute in ranching, which accounts for roughly 80% of deforestation in the Amazon, nearly all of it illegal. “Cows move around,” explains Paulo Pianez of Marfrig. Every fattening farm the big meatpackers buy from has, on average, 23 of its own suppliers. Current monitoring doesn’t cover ranchers who breed and graze cattle, so it misses 85-90% of deforestation. Rogue fattening farms can also “launder” cattle by moving them to lawful farms—perhaps their own—right before selling them. A new Greenpeace report alleges that through this mechanism JBS, Marfrig and Minerva ended up selling beef from farms that deforested a protected Amazon reserve on the border between Brazil and Bolivia. They said they had not known about any illegality.

One reason that soya giants seem more serious than meat producers about reducing deforestation a network of investors concerned about sustainability, is that most soya is exported. The EU is the second-top destination after China. But companies struggle to get people to pay more for a “hidden commodity”… But few people will pay extra for chicken made with sustainable soya, which explains why just 2-3% is certified deforestation-free. ….Four-fifths of Brazilian beef, by contrast, is eaten in Brazil. Exports go mostly to China, Russia and the Middle East, where feeding people is a higher priority than saving trees. Investors, for their part, see beef firms as unsexy businesses with thin margins

According to soya growers, multinational firms failed to raise $250m to launch a fund for compensating farmers who retain woodland. “They demand, demand, demand, but don’t offer anything in return,” complains Ricardo Arioli….

Reducing deforestation will require consensus on tricky issues like the fate of tens of thousands of poor settlers on public lands in the Amazon, where half of deforestation takes place….

Preserving Seeds that Feed the World: the Svalbard Global Seed Vault

Six hundred miles from the North Pole, on an island the size of West Virginia, at the end of a tunnel bored into a mountain, lies a vault filled with more than 1 million samples of seeds harvested from 6,374 species of plants grown in 249 locations around the globe.The collection, the largest of its kind, is intended to safeguard the genetic diversity of the crops that feed the world.  If disaster wipes out a plant, seeds from the vault could be used to restore the species. If pests, disease or climate change imperil a food source, a resistant trait found among the collection could thwart the threat.

While some countries have their own seed banks—Colorado State University houses one for the U.S.—the Svalbard Global Seed Vault serves as a backup. The vault, built in 2008 at a cost of about $9 million, is owned and maintained by Norway, but its contents belong to the countries and places that provide the samples.  “It works like a safe-deposit box at the bank,” said Cary Fowler, an American agriculturalist who helped found the vault. “Norway owns the facility, but not the boxes of the seeds.”

In 2015, after the International Center for Agricultural Research in the Dry Areas was destroyed in the Syrian civil war, scientists who had fled the country withdrew seeds to regenerate the plants in Lebanon and Morocco.  “It had one of the world’s biggest and best collections of wheat, barley, lentils, chickpeas, faba beans and grass pea,” Dr. Fowler said. “It was the chief supplier of a disease-resistant wheat variety for the Middle East.”  In 2017, the group returned copies of its seeds to the vault.

The 18,540-square-foot seed vault includes three rooms with the capacity to house 4.5 million samples of 500 seeds each—a maximum of 2.25 billion seeds. The environment’s natural temperature remains below freezing year round, but the seeds are stored at a chillier -18 degrees Celsius, or around -0.4 degrees Fahrenheit. They’re expected to last for decades, centuries or perhaps even millennia….

While dwindling diversity might not seem like an imminent threat, four chemical companies now control more than 60% of global proprietary seed sales…That concentration of power, some worry, could lead to less agricultural variety and more genetic uniformity…In the meantime, the seed vault (which doesn’t store genetically modified seeds) will continue to accept deposits in an effort to preserve all of the options it can.

Choking the Water: Dams, Dams and More Dams

Since Tibet is part of China, Chinese engineers have been making the most of that potential. They have built big dams not only on rivers like the Yellow and the Yangzi, which flow across China to the Pacific, but also on others, like the Brahmaputra and the Mekong, which pass through several more countries on their way to the sea.

China has every right to do so. Countries lucky enough to control the sources of big rivers often make use of the water for hydropower or irrigation before it sloshes away across a border. But If the countries nearest the source of water, like China,  suck up too much of the flow, or even simply stop silt flowing down or fish swimming up by building dams, the consequences in the lower reaches of the river can be grim: parched crops, collapsed fisheries, salty farmland.

Tension and recrimination have been the order of the day for China and its neighbours… In part, this is because a river like the Mekong does not contain enough water to go round. China has already built 11 dams across the main river (never mind its tributaries) and has plans for eight more; the downstream states have built two and are contemplating seven more. Last year, during a drought, the river ran so low that Cambodia had to turn off a big hydropower plant. Even when rainfall is normal, the altered flow and diminished siltation are causing saltwater to intrude into the Mekong delta, which is the breadbasket of Vietnam, and depleting the fish stocks that provide the only protein for millions of poor Cambodians.

China has long resisted any formal commitment to curb its construction of dams or to guarantee downstream countries a minimum allocation of water. It will not even join the Mekong River Commission, a body intended to help riparian countries resolve water-sharing disputes…

China has not signed any agreements about managing the Mekong with the other countries it flows through, so is not obliged to share a particular amount of water with them, nor even provide data on the flow or any warning about the operations of its dams. It does provide the Mekong River Commission with a trickle of information about water levels and planned releases from dams, which helps with flood-control lower down the river

Elephants and Cattle: Benefits of Co-existence

Wildlife and cattle can coexist.  In fact, elephants can help distribute nutrients into the soil, via their poop and their habit of knocking over trees…Common grass contained about 50% more nitrogen in the grazing areas with elephants than the areas without them, making that grass more nutritious. That should benefit both cows and smaller wildlife, such as gazelles….This is why ranchers must protect elephants.

What Shrimp and Beef Have in Common? carbon footprint

Shrimp farms tend to occupy coastal land that used to be covered in mangroves. Draining mangrove swamps to make way for aquaculture is even more harmful to the atmosphere than felling rainforest to provide pasture for cattle. A study conducted in 2017 by cifor, a research institute, found that in both these instances, by far the biggest contribution to the carbon footprint of the resulting beef or shrimp came from the clearing of the land. As a result, CIFOR concluded, a kilo of farmed shrimp was responsible for almost four times the greenhouse-gas emissions of a kilo of beef

Eating wild shrimp is not much better: catches are declining around the world as a result of overfishing. Trawlers can pull as much as 20kg of by-catch from the sea for every kilo of shrimp. And reports abound of the appalling treatment of workers on shrimp-fishing vessels, including human-trafficking and child labour. When UN investigators interviewed a sample of Cambodians who had escaped virtual slavery on Thai fishing boats, 59% of them reported seeing fellow crew-members murdered by the captain.


Most of the world’s shrimp and prawns come from Asia. The continent accounts for 85% of the farmed sort and 74% of the wild catch. Global sales were around $45bn in 2018 and are thought to be growing by about 5% a year. But the industry is controversial, not just because of its part in global warming. Razing mangroves also leaves coastal regions vulnerable to flooding. Many shrimp farms are unsanitary; ponds often have to be abandoned after a few years because of problems with disease and pollution.

All this has given one Singaporean company a brain wave. “Farmed shrimps are often bred in overcrowded conditions and literally swimming in sewage water. We want to disrupt that—to empower farmers with technology that is cleaner and more efficient,” says Sandhya Sriram, one of the founders of Shiok Meats. The firm aims to grow artificial shrimp, much as some Western firms are seeking to create beef without cows. The process involves propagating shrimp cells in a nutrient-rich solution. Ms Sriram likens it to a brewery, disdaining the phrase “lab-grown”….The hitch is that producing shrimp in this way currently costs $5,000 a kilo.

Sewers: Turning Wastewater into a Valuable Resource

The world’s growing flows of wastewater offer a largely untapped, potentially lucrative source of energy, agricultural fertilizers, and water for irrigation. The opportunities will increase as the annual volume of wastewater—now 380 billion cubic meters—expands by an estimated 51% by 2050, as populations and incomes multiply, says a team led by researchers at United Nations University’s Institute for Water, Environment, and Health. About 13% of global demand for fertilizer could be met by recovering nitrogen, phosphorus, and potash from wastewater; such use provides a bonus, diverting nutrients from waterways, where they can create harmful eutrophication. Sewage also offers an alternative energy source…..

How Sand Extraction Damages Ecosystems

The world uses nearly 50bn tonnes of sand and gravel a year—almost twice as much as a decade ago. No other natural resource is extracted and traded on such an epic scale, bar water. Demand is greatest in Asia, where cities are growing fast (sand is the biggest ingredient in concrete, asphalt and glass). China got through more cement between 2011 and 2013 than America did in the entire 20th century (the use of cement is highly correlated with that of sand).

Since the 1960s Singapore—the world’s largest importer of sand—has expanded its territory by almost a quarter, mainly by dumping it into the sea. The OECD thinks the construction industry’s demand for sand and gravel will double over the next 40 years. Little wonder then that the price of sand is rocketing. In Vietnam in 2017 it quadrupled in just one year.

In the popular imagination, sand is synonymous with limitlessness. In reality it is a scarce commodity, for which builders are now scrabbling. Not just any old grains will do. The United Arab Emirates is carpeted in dunes, but imports sand nonetheless because the kind buffeted by desert winds is too fine to be made into cement. Sand shaped by water is coarser and so binds better. Extraction from coastlines and rivers is therefore surging. But according to the United Nations Environment Programme (UNEP), Asians are scooping up sand faster than it can naturally replenish itself. In Indonesia some two dozen small islands have vanished since 2005. Vietnam expects to run out of sand this year.

All this has an environmental cost. Removing sand from riverbeds deprives fish of places to live, feed and spawn. It is thought to have contributed to the extinction of the Yangzi river dolphin. Moreover, according to WWF, a conservation group, as much as 90% of the sediment that once flowed through the Mekong, Yangzi and Ganges rivers is trapped behind dams or purloined by miners, thereby robbing their deltas both of the nutrients that make them fecund and of the replenishment that counters coastal erosion. As sea levels rise with climate change, saltwater is surging up rivers in Australia, Cambodia, Sri Lanka and Vietnam, among other places, and crop yields are falling in the areas affected. Vietnam’s agriculture ministry has warned that seawater may travel as far as 110km up the Mekong this winter. The last time that happened, in 2016, 1,600 square kilometres of land were ruined, resulting in losses of $237m. Locals have already reported seeing dead fish floating on the water.

 
Curbing sand-mining is difficult because so much of it is unregulated. Only about two-fifths of the sand extracted worldwide every year is thought to be traded legally, according to the Global Initiative Against Transnational Organised Crime. In Shanghai miners on the Yangzi evade the authorities by hacking transponders, which broadcast the positions of ships, and cloning their co-ordinates. It is preferable, of course, to co-opt officials. Ministers in several state governments in India have been accused of abetting or protecting illegal sand-mining. “Everybody has their finger in the pie,” says Sumaira Abdulali of Awaaz Foundation, a charity in Mumbai. She says she has been attacked twice for her efforts to stop the diggers.

Genetically Modified Crops May Become the Norm: the case of Golden Rice

Golden Rice is a genetically modified (GM) crop that could help prevent childhood blindness and deaths in the developing world. Ever since Golden Rice first made headlines nearly 20 years ago, it has been a flashpoint in debates over GM crops. Advocates touted it as an example of their potential benefit to humanity, while opponents of transgenic crops criticized it as a risky and unnecessary approach to improve health in the developing world.

Now, Bangladesh appears about to become the first country to approve Golden Rice for planting..Golden Rice was developed in the late 1990s by German plant scientists Ingo Potrykus and Peter Beyer to combat vitamin A deficiency, the leading cause of childhood blindness. Low levels of vitamin A also contribute to deaths from infectious diseases such as measles. Spinach, sweet potato, and other vegetables supply ample amounts of the vitamin, but in some countries, particularly those where rice is a major part of the diet, vitamin A deficiency is still widespread; in Bangladesh it affects about 21% of children.

To create Golden Rice, Potrykus and Beyer collaborated with agrochemical giant Syngenta to equip the plant with beta-carotene genes from maize. They donated their transgenic plants to public-sector agricultural institutes, paving the way for other researchers to breed the Golden Rice genes into varieties that suit local tastes and growing conditions.

The Golden Rice under review in Bangladesh was created at the International Rice Research Institute (IRRI) in Los Baños, Philippines. Researchers bred the beta-carotene genes into a rice variety named dhan 29…Farmers in Bangladesh quickly adopted an eggplant variety engineered to kill certain insect pests after its 2014 introduction, but that crop offered an immediate benefit: Farmers need fewer insecticides. Golden Rice’s health benefits will emerge more slowly,

How to Own a Foreign Country: the Strategy of Gulf States in Egypt and Sudan

Nile has become a battleground. Countries that sit upriver and wealthy Gulf states are starting to use the Nile more than ever for water and electricity. That means less water for the 250 million-plus small farmers, herders and city dwellers in the Nile basin.  Dams funded by foreign countries including China and oil-rich neighbors like Saudi Arabia and other Gulf states are tapping the river to irrigate industrial farms and generate electricity. Crops grown using Nile water are increasingly shipped out of Africa to the Middle East, often to feed livestock such as dairy cows

Exporting crops to feed foreign animals while borrowing money to import wheat is “almost insane,” Sudan’s new prime minister, Abdalla Hamdok, said in an interview. “It’s exporting water, basically. We could be growing wheat and getting rid of half our import bill,” he said. Mr. Hamdok’s predecessor, dictator Omar al-Bashir, is in prison after an uprising sparked by rising prices for food….

The most dramatic change to the Nile in decades is rising in Ethiopia, where the Blue Nile originates. Ethiopia, which has one of the world’s fastest-growing economies, turned to China to help finance the $4.2 billion Grand Ethiopian Renaissance Dam project to generate electricity. While the dam, located just miles from the Sudan border, won’t supply water for farms and cities, its massive reservoir will affect the flow of water.

Downstream, Egypt is worried that Ethiopia will try to quickly fill the reservoir beginning in 2020. The issue is “a matter of life and death for the nation,” Egyptian President Abdel Fattah Al Sisi said in televised remarks in 2017. “No one can touch Egypt’s share of water.” A spokesman for Ethiopia’s Ministry of Foreign Affairs said in a September press conference that “any move that does not respect Ethiopia’s sovereignty and its right to use the Nile dam has no acceptance.”  Sharing of the Nile’s waters has long been governed by international treaties, with Egypt claiming the vast majority. Since Ethiopia wasn’t included in those treaties, it was never provided an allotment of water. Ethiopia’s massive dam has thrown a wrench into past agreements…

Sudan is stuck in the middle. Much of the water that flows through the country is already allocated. “Sudan actually doesn’t have that much free water available,” says Harry Verhoeven, author of “Water, Civilisation and Power in Sudan.”  By early 2015, Saudi Arabia doubled its investment in Sudan’s agriculture sector to $13 billion, equaling about one-third of all foreign investment in Sudanese industry….The contrast between verdant export crops watered by the Nile and parched villages was visible in the area where protests started in December 2019, during a nationwide wheat shortage.   The protesters were angry about food prices, poor job prospects, social strictures and Sudan’s moribund economy, Mr. Alsir says. “We’re surrounded by farms,” he says. “But we’re not getting any of it.

Past a rocky expanse next to the village flows a deep canal, green with weeds, dug a decade ago by a Saudi-owned company called Tala Investment Co. It runs from the Nile about 10 miles to Tala’s farm, which leases its land from the government.  Tala grows crops for export and maximizes profits using Sudan’s “cheap manpower,” the company’s website says….The alfalfa is shipped 400 miles overland to Port Sudan and then across a nearly 200-mile stretch of the Red Sea to Jeddah in Saudi Arabia, then is used for animal feed….

The Aswan dam  In Egypt is primarily used to generate electricity. But a sprawling desert farm, the Toshka project to the west, taps the reservoir. That is where Saudi Arabia and the U.A.E. have made some of their biggest agricultural investments in Egypt in the past decade.  The strategy there is straightforward, says Turki Faisal Al Rasheed, founder of Saudi agriculture company Golden Grass Inc., which has explored purchasing farms in Egypt and Sudan. “When you talk about buying land, you’re not really buying land,” he says. “You’re buying water.”

Even with all that water dedicated to growing crops, Egypt  is rapidly outstripping its resources.  This is because he country’s population is forecast to grow 20% to 120 million by 2030, and to 150 million by 2050.  Access to water in Egypt is increasingly uncertain. The country’s annual per capita water use dipped below 24,000 cubic feet in recent years and is expected to fall below 18,000 cubic feet by 2030, a level defined as “absolute water scarcity,” according to the United Nations. The comparable figure in the U.S. is 100,000 cubic feet, enough to fill an Olympic swimming pool.  Saudi Arabia and the U.A.E. control about 383,000 acres of land in Egypt, an expanse nearly twice the size of New York City, according to Land Matrix. The main crops are corn, potatoes, wheat, alfalfa, barley and fruit such as grapes that are exported back home.

Mr. Sisi is now looking for new places to grow food. In 2015 he launched a program to expand arable land by more than 1.5 million acres in the country, part of which will tap into the Nubian aquifer, an irreplaceable ancient store of water beneath the Sahara. Saudi and U.A.E. companies have bid for lands in the project, according to the New Egyptian Countryside Development Co., which is managing the project.  Mr. Al Rasheed, the Saudi farm owner in Egypt, says that for him and others from the Gulf, farming along the Nile is about building regional influence as much as ensuring food supplies. “Food is the ultimate power,” he says.

When Logging Works: “Every Part of the Tree”

The rapacious industrialisation of the Finnish forest, which covers three-quarters of the country’s landscape, looks the antithesis of tree-hugging environmentalism. The forest is home to wolves, bears, deer and many other species of wildlife, and its trees lock away carbon that would otherwise be in the air, warming the atmosphere. Yet Metsä Group, which operates the Äänekoski pulp mill, claims the very opposite.  Metsä is ultimately controlled by a co-operative belonging to more than 100,000 families who have each owned large chunks of the forest for generations. For every tree harvested, four saplings are planted. These are allowed to grow for a few years and are then thinned to encourage the best specimens to develop vigorously. The thinnings, however, are not wasted. They are sent to the mill. The mature trees, meanwhile, are harvested when they are between six and ten decades old. The consequence of this husbandry, according to Finland’s Natural Resources Institute, is that the annual growth of trees in Finland exceeds the volume of felling and natural loss by over 20m cubic metres, despite the increasing demand for wood.

As for the mill itself, Metsä’s stated aim is to make best use of every part of a tree, both to maximise the value of its wood and, where possible, to continue to lock up its carbon. To this end, besides the bread-and-butter business of turning out planks and plywood, the firm has come up with several new ideas. Three are of particular interest. One is a better way of converting wood pulp into fibre that can be turned into textiles. A second is to produce plastic-free cardboard cartons which can be used as food containers and then recycled. The third is to find employment for lignin, a by-product of the pulping process which is, at the moment, usually burned…

Metsä has also teamed up with Itochu, a Japanese trading company with a large clothing business, to make fabric that will compete with oil-based synthetic fibres and provide an alternative to cotton, the growing of which requires a lot of land, irrigation and pesticides. Some fabrics—rayon, for example—can be made from wood….

The complex processes involved in processing wood result in several “sidestreams”. These are wastes that become raw materials for other processes. They include sulphuric acid, which is re-used by the mill, and biogas, tall oil (a byproduct of papermaking) and lignin—carbon-rich materials burnt to produce electricity. This powers the mill, and yields a surplus which is exported to the national grid. As a consequence, unlike some wood mills, the Äänekoski plant uses no fossil fuels.

Bio-Energy and Food Security

In the effort to keep the planet from reaching dangerous temperatures, a hybrid approach called BECCS (bioenergy with carbon capture and storage) has a seductive appeal. Crops suck carbon dioxide (CO2) from the atmosphere, power plants burn the biomass to generate electricity, and the emissions are captured in a smokestack and pumped underground for long-term storage. Energy is generated even as CO2 is removed: an irresistible win-win. But, the United Nations’s climate panel sounded a warning about creating vast bioenergy plantations, which could jeopardize food production, water supplies, and land rights for poor farmers.

In an earlier special report in October 2018, IPCC called for holding the rise in global average temperatures to no more than 1.5°C above preindustrial conditions to avoid the worst consequences of climate change. It emphasized that cutting emissions won’t be enough to reach that goal. Replacing coal with renewable energy, and significantly cutting oil and natural gas, would still leave gigatons of excess carbon in the atmosphere. BECCS could remove it, computer models suggested, if several million square kilometers—an area the size of India—were devoted to energy crops.

But the 2019 IPCC report examines the consequences of deploying BECCS on that vast scale and concludes it could “greatly increase” the demand for agricultural land. The pressure on conventional crops could compromise food security, as happened in 2007 when rising U.S. corn ethanol production contributed to a spike in food prices. (In Mexico, the price of tortillas, a staple for the poor, rose 69% between 2005 and 2011.) The bioenergy plantations could also take a toll on biodiversity—as is happening in Southeast Asia, where plantations producing palm oil for biodiesel as well as food are displacing diverse tropical forest. And they could suck up scarce water, especially in drylands, where irrigation of crops might deplete local supplies, the IPCC report says.

Industrial bioenergy crops can lead to the same kinds of problems as intensive food production, such as the contamination of water from excess fertilizer. Scaling up bioenergy in developing countries can also exacerbate social problems like the loss of land by small farmers.

The Disappearing Birds

North America’s birds are disappearing from the skies at a rate that’s shocking even to ornithologists. Since the 1970s, the continent has lost 3 billion birds, nearly 30% of the total, and even common birds such as sparrows and blackbirds are in decline, U.S. and Canadian researchers reported in the September 2019 Issue of Science Magazine…  Five  years ago, PM Rosenberg a conservation biologist decided to take a broader look at what is happening in North America’s skies.

“I frankly thought it was going to be kind of a wash,” Rosenberg says. He expected rarer species would be disappearing but common species would be on the rise, compensating for the losses, because they tend to be generalists, and more resilient. Indeed, waterfowl and raptors are thriving, thanks to habitat restoration and other conservation efforts. But the declines in many other species, particularly those living along shorelines and in grasslands, far exceeded those gains, Rosenberg and his colleagues report. Grassland birds have declined by 53% since 1970—a loss of 700 million adults in the 31 species studied, including meadowlarks and northern bobwhites. Shorebirds such as sanderlings and plovers are down by about one-third, the team says. Habitat loss may be to blame.

The familiar birds that flock by the thousands in suburbs were not exempt. “There’s an erosion of the numbers of common birds,” Rosenberg says. His team determined that 19 common species have each lost more than 50 million birds since 1970. Twelve groups, including sparrows, warblers, finches, and blackbirds, were particularly hard hit. Even introduced species that have thrived in North America, such as starlings and house sparrows, are losing ground.  “When you lose a common species, the impact will be much more massive on the ecosystem and ecosystem services,” says Gerardo Ceballos, an ecologist and conservation biologist at the National Autonomous University of Mexico in Mexico City. “It’s showing the magnitude of the problem.”

Some of the causes may be subtle. Last week, toxicologists described how low doses of neonicotinoids—a common pesticide—made migrating sparrows lose weight and delay their migration, which hurts their chances of surviving and reproducing. Climate change, habitat loss, shifts in food webs, and even cats may all be adding to the problem, and not just for birds. 

Weather radar data revealed similarly steep declines. Radar detects not just rain, but also insect swarms and flocks of birds, which stand out at night, when birds usually migrate. “We don’t see individual birds, it’s more like a big blob moving through airspace,” explains Cornell migration ecologist Adriaan Dokter. He converted “blobs” from 143 radar stations into biomass. Between 2007 and 2017, that biomass declined 13%, the Science paper reports. The greatest decline was in birds migrating up the eastern United States….

A Cure Worse than the Disease? Biofuels in Planes

The 2019 report by the Rainforest Foundation Norway RFN is called ‘Destination Deforestation’ and reviewed the role of the aviation industry in contributing to the climate crisis, concluding that there’s a high risk that increased use of palm and soy-based biofuel in planes will lead to increased deforestation.

Finland, the world’s largest producers of renewable diesel and the only EU country that gives additional incentives for the use of palm oil products to manufacture biofuel, could spearhead the race towards deforestation, as areas of rainforest in countries like Indonesia or in South America are cleared to plant crops that will later be used to produce the fuel.  RFN says that meeting the aviation industry’s own climate-change targets to reduce emissions could result in 3.2 million hectares of tropical forest lost, an area larger than Belgium.

Researchers at Rainforest Foundation Norway believe the Finnish incentives for (Palm Fatty Acid Distillate) PFAD-based biofuels are likely to contribute to this deforestation, since Finland’s state-owned oil company Neste produces half of the world’s renewable diesel.  “Finland continues to treat the palm oil by-product PFAD as a waste, eligible for additional incentives. In addition, Finland is home to Neste, the world’s largest producer of hydrotreated biodiesel, and uses PFAD as a raw material. Therefore, Finland’s program could contribute to the massive deforestation discussed in our report” he explains.

With Finland left isolated as the only EU country to pay producers to use waste-classified PFAD in biofuel production, Rainforest Foundation Norway cautions that the country risks becoming a dumping ground for unsustainable raw material….“As long as PFAD is classified as ‘waste’, it enjoys huge incentives from the state. Biofuels made out of PFAD are completely exempt from carbon dioxide tax in Finland. Additionally, PFAD’s emissions can be discounted, and it is not subject to the same sustainability criteria as other raw materials.

With ‘flight shame’ gaining more momentum across the world, the aviation industry is desperate to find ways to make flying compatible with climate goals. While replacing fossil fuels with renewables sounds like a great idea, the sustainability of biofuels is highly dependent on the raw materials used to produce them…The most common aviation biofuels, Hydrogenated Esters and Fatty Acids (HEFA) fuels are produced from vegetable oils and animal fats. While the use of waste oils and other recycled materials is possible, the most viable raw materials for HEFA jet fuels are food crops.  “The cheapest and most readily available raw materials for HEFA jet fuel are palm oil and soy oil, which are closely linked to tropical deforestation” Ranum says.  The experts suggest that aiming to reduce emissions by increasing demand for palm and soy oil is a cure worse than the disease.

The Fight Against Toxic Algae

Signs posted around the Grand Lake, Ohio read: “Danger: Avoid all contact with the water.”  When dangerously high levels of toxins from blue-green algae in Grand Lake, Ohiio were publicized in 2009, many residents and tourists stopped using the 13,000-acre lake in northwest Ohio. Hotel revenue and home values sank for several years as algae bloomed in the state’s largest inland lake.

Greenish water still laps at Grand Lake’s shores, but recent water samples show that the amount of algae-feeding nutrients entering the lake is down significantly. State, federal and private donations covered more than $10 million in projects aimed at improving water quality. More people are boating on the lake again. Grand Lake could now serve as an example for communities with algae problems across the nation, experts say.

Algal blooms are on the rise, from Lake Erie to the Florida Everglades. In August 2019, the Environmental Protection Agency listed algae-related beach closures or health advisories in 23 states, and it said other blooms may not have been reported. In 2010, the EPA found that 20% of 50,000 lakes surveyed had been affected by phosphorous and nitrogen pollution, which feeds algae.e  Cleaning up bodies of water choked with toxic algae has proved difficult. The project to repair Grand Lake, once one of the most polluted by algae in the nation, is one of the clearest successes. It shows cleanup is possible, but also expensive and time-consuming.

“It’s not restored yet, but it’s on the road to recovery,” said Stephen Jacquemin, an associate professor of biology at Wright State University-Lake Campus in Celina.  Beginning in 2012, wetlands areas were built around the lake, which was hand dug in the 1830s. The thick stands of bulrushes and other plants have reduced phosphorous and nitrogen levels in water entering the wetlands before reaching the lake by as much as 90%, Dr. Jacquemin said.  Three wetland areas, which cost a total of about $6 million to build, are constructed as a series of interconnected pools that allow particulates to settle out and plants and microbes to remove nutrients.

 The state’s Department of Natural Resources has also dredged the lake bottom to remove nutrient-loaded sediment, and tried to clean up one of Grand Lake’s beaches near St. Marys by building a rock jetty and installing aerators and a curtain to filter water. Recent water tests there showed levels below 6 parts per billion of the toxin microcystin, under Ohio’s threshold of 20 parts per billion for avoiding contact with water.

The Truth About Forest Fires

BBC has used satellite data to assess the severity of fires in Brazil, Indonesia, Siberia and Central Africa.  It has concluded that although fires in 2019 have wrought significant damage to the environment, they have been worse in the past.   More than 35,000 fires have been detected so far in 2019 in East Asia  spreading smoky haze to Malaysia, Singapore, the south of Thailand and the Philippines, causing a significant deterioration in air quality.  But this is substantially fewer than many other years including those, such as 2015, exacerbated by the El Nino effect which brought unusually dry weather.

Haze Pollution

In Indonesia, peatland is set alight by corporations and small-scale farmers to clear land for palm oil, pulp and paper plantations, and can spread into protected forested areas.  The problem has accelerated in recent years as more land has been cleared for expanding plantations for the lucrative palm oil trade.  Old palm trees on plantations that no longer bear fruit are often set on fire to be replaced by younger ones.

The number of recorded fires in Brazil rose significantly in 2019, but there were more in most years in the period 2002 to 2010.  There is a similar pattern for other areas of Brazilian forestry that are not part of the Amazon basin.  For 2019, we have data up to the end of August, and the overall area burnt for those eight months is 45,000 sq km. This has already surpassed all the area burnt in 2018, but appears unlikely to reach the peaks seen in the previous decade… “Fire signals an end of the deforestation process,” says Dr Michelle Kalamandeen, a tropical ecologist on the Amazon rainforest.  “Those large giant rainforest trees that we often associate with the Amazon are chopped down, left to dry and then fire is used as a tool for clearing the land to prepare for pasture, crops or even illegal mining.”

The environmental campaign group Greenpeace has called the fires that have engulfed the Russian region of Siberia this year one of the worst outbreaks this century.  The cloud of smoke generated was reported to have been the size of all the European Union countries combined.  Forest fires in Siberia are common in the summer, but record-breaking temperatures and strong winds have made the situation particularly bad.  Russia’s Federal Forestry Agency says more than 10 million hectares (100,000 sq km) have been affected since the start of 2019, already exceeding the total of 8.6 million for the whole of 2018…. Drawing on data for the number of fires, it is clear that there have been other bad years, notably in 2003.

Nasa satellites have identified thousands of fires in Angola, Zambia and DR Congo.However, these have not reached record levels.  “I don’t think there’s any evidence that the fires we’re seeing in Africa are worse than we’ve seen in recent years,” Denis McClean, of the UN Disaster Risk Reduction agency, told the BBC.  According to data analysed by Global Forest Watch, fires in DR Congo and Zambia are just above average for the season but have been higher in past years.  In Angola, however, fires have been reported at close to record levels this year.

Some have drawn comparisons with the situation in the Amazon, but the fires in sub-Saharan Africa are different.  Take DR Congo – most fires are being recorded in settled parts of the country’s southern, drier forest and savannah areas, and so far not in tropical rainforest.  Experts say it is difficult to know what is causing these fires, which are seasonal. Many are likely to be on grassland, woodland or savannah in poor farming communities.  “Fires are very important landscape management tools and are used to clear land for planting crops,” says Lauren Williams, a specialist in Central and West African forests at the World Resources Institute.

How to Manage Water Like Money and Fail: Australia

Australia’s Darling River…provided fresh water to farmers seeking to tame Australia’s rugged interior.  No longer. The Darling River hasn’t flowed for eight months, with long stretches completely dried up. A million fish died there in January 2019.  Kangaroos, lizards and birds became sick or died after drinking from toxic pools of stagnant water.  Australia’s water-trading market is drawing blame. The problems with the system, created more than a decade ago, have arisen as similar programs are being considered in the U.S.

Water crises are unfolding across the world as surging populations, industrial-scale farming and hotter temperatures deplete supplies.  Australia thought it had the answer: a cap-and-trade system that would create incentives to use water efficiently and effectively in the world’s driest inhabited continent. But the architects of water trading didn’t anticipate that treating water as a commodity would encourage theft and hoarding.   A report produced for a state resources regulator found the current situation on the Darling was caused by too much water being extracted from the river by a handful of big farmers. Just four license holders control 75% of the water extracted from the Barwon-Darling river system.

The national government, concerned that its water-trading experiment hasn’t turned out as intended, in August 2019 requested an inquiry by the country’s antitrust regulator into water trading.  Anticorruption authorities are investigating instances of possible fraud, water theft and deal making for water licenses. In one case, known as Watergate, a former agriculture minister allegedly oversaw the purchase of a water license at a record price from a Cayman Islands company co-founded by the current energy minister. The former agriculture minister said he was following departmental advice and had no role in determining the price or the vendor. The energy minister said he is no longer involved with the company and received no financial benefit from the deal.

Since 2007, Australia has allowed not only farmers but also investors who want to profit from trading to buy and sell water shares. The water market is now valued at some $20 billion.    But making water valuable had unintended consequences in some places. “Once you create something of real value, you should expect people to attempt to steal it and search for ways to cheat,” says Mike Young, a University of Adelaide professor. “It’s not rocket science. Manage water like money, and you are there.”  Big water users have stolen billions of liters of water from rivers and lakes, according to local media investigations and Australian officials, often by pumping it secretly and at night from remote locations that aren’t metered. A new water regulator set up in New South Wales investigated more than 300 tips of alleged water thefts in its first six months of operation.  In 2018, authorities charged a group of cotton farmers with stealing water, including one that pleaded guilty to pumping enough illegally to fill dozens of Olympic-size swimming pools.  Another problem is that water trading gives farmers an incentive to capture more rain and floodwater, and then hoard it, typically by building storage tanks or lining dirt ditches with concrete. That enables them to collect rain before it seeps into the earth or rivers.

The subsequent water shortages, combined with trading by dedicated water funds and corporate farmers, have driven up prices. Water in Australia’s main agricultural region, the Murray-Darling river basin, now trades at about $420 per megaliter, or one million liters, compared with as low as $7 in previous years.  David Littleproud, Australia’s water-resources minister, says 14% of water licenses are now owned by investors. “Is that really the intent of what we want this market to be?” he asks. “Water is a precious commodity.”

How to Change the World: Take Seeds to Space and Irradiate them with Cosmic Rays

With 19% of the world’s population but only 7% of its arable land, China is in a bind: how to feed its growing and increasingly affluent population while protecting its natural resources. The country’s agricultural scientists have made growing use of nuclear and isotopic techniques in crop production over the last decades. In cooperation with the IAEA and the Food and Agriculture Organization of the United Nations (FAO), they are now helping experts from Asia and beyond in the development of new crop varieties, using irradiation.

While in many countries, nuclear research in agriculture is carried out by nuclear agencies that work independently from the country’s agriculture research establishment, in China the use of nuclear techniques in agriculture is integrated into the work of the Chinese Academy of Agricultural Sciences (CAAS) and provincial academies of agricultural sciences. This ensures that the findings are put to use immediately.

And indeed, the second most widely used wheat mutant variety in China, Luyuan 502, was developed by CAAS’s Institute of Crop Sciences and the Institute of Shandong Academy of Agricultural Sciences, using space-induced mutation breeding. It has a yield that is 11% higher than the traditional variety and is also more tolerant to drought and main diseases.  It has been planted on over 3.6 million hectares – almost as large as Switzerland. It is one of 11 wheat varieties developed for improved salt and drought tolerance, grain quality and yield.

Through close cooperation with the IAEA and FAO, China has released over 1,000 mutant crop varieties in the past 60 years, and varieties developed in China account for a fourth of mutants listed currently in the IAEA/FAO’s database of mutant varieties produced worldwide.

The Institute uses heavy ion beam accelerators, cosmic rays and gamma rays along with chemicals to induce mutations in a wide variety of crops, including wheat, rice, maize, soybean and vegetables….Indonesia’s nuclear agency, BATAN, and CAAS are looking for ways to collaborate on plant mutation breeding

Space-induced mutation breeding
 
Irradiation causes mutation, which generates random genetic variations, resulting in mutant plants with new and useful traits. Mutation breeding does not involve gene transformation, but rather uses a plant’s own genetic components and mimics the natural process of spontaneous mutation, the motor of evolution. By using radiation, scientists can significantly shorten the time it takes to breed new and improved plant varieties.

Space-induced mutation breeding, also called space mutagenesis, involves taking the seeds to space, where cosmic rays are stronger, and these rays are used to induce mutation.  Satellites, space shuttles and high-altitude balloons are used to carry out the experiments. One advantage of this method is that the risk of damaging the plants are lower than when using gamma irradiation on earth.

The Biopiracy Backlash

Indonesia‘s rich biodiversity and complex geology have lured scientists from abroad for centuries. But a law adopted on 16 July 2019 by Indonesia’s parliament may convince some to go elsewhere. The legislation includes strict requirements on foreign scientists doing research in Indonesia, including the need to recruit local collaborators and a near-ban on exporting specimens, along with stiff sanctions, including jail time, for violators.

Muhammad Dimyati, director-general of research development at Indonesia’s Ministry of Research, Technology, and Higher Education (commonly known as RISTEK) in Jakarta, says the law is needed to protect Indonesia’s natural resources and develop the country’s research enterprise. But some Indonesian scientists fear the consequences. “Our international collaborations will be stifled,” says Berry Juliandi, a biologist at Bogor Agricultural University and secretary of the Indonesian Young Academy of Science. Indeed, marine biologist Philippe Borsa of the French Research Institute for Development in Montpellier says the law—and an increasingly unfriendly climate for foreign researchers—is a reason for him not to return to Indonesia, where he has studied the phylogeography of stingrays.

The new law also establishes the National Research Agency, a giant new institution that may subsume most government research centers, including the Indonesian Institute of Sciences (LIPI) in Jakarta. Details still need to be fleshed out, but some scientists worry the new agency will concentrate too much power in a few hands. The law’s most contentious provisions, however, are those that apply to foreign researchers.

From now on, their research has to be “beneficial for Indonesia.” They need to get ethical clearance from an Indonesian review board for every study, submit primary data and published papers to the government, involve Indonesian scientists as equal partners, and share any benefits, such as the proceeds from new drugs, resulting from the study. Researchers can’t take samples or even digital information out of the country, except for tests that cannot be done in Indonesian labs, and to do so, they need a so-called material transfer agreement (MTA) using a template provided by the government.

In most cases, violators will lose their research permit, but some offenses carry steeper penalties. Scientists who fail to obtain a proper permit will be blacklisted for 5 years; repeat offenders risk a $290,000 fine. Failure to comply with the MTA requirements is punishable by 2 years in prison or a $145,000 fine. ..Indonesia has become increasingly concerned about biopiracy.  In 2018,, for instance, a dispute erupted over a genetic study of Sulawesi’s “sea nomads”—an indigenous fishing group that appears to have evolved bigger spleens to store oxygenated blood during long dives. Indonesian researchers called it an example of Western “helicopter science.”. 

Megalara garuda

A 2017 document introducing the new law, signed by RISTEK Minister Mohamad Nasir, singled out another alleged example: the discovery of Megalara garuda, a giant venomous wasp, on Sulawesi, published in 2012 by entomologist Lynn Kimsey of the University of California (UC), Davis, along with a German researcher who found the same insect in a Berlin collection. LIPI entomologist Rosichon Ubaidillah tells Science that he and a junior colleague collected the wasps and that he suggested the name garuda—a mythical bird and national symbol of Indonesia—during a visit to UC Davis. But neither of them was a co-author on the paper; Ubaidillah was mentioned in an acknowledgement, his colleague not at all. Kimsey violated a memorandum of understanding between LIPI and UC Davis, he adds. LIPI, enraged, asked Kimsey to return the wasps she took home.

Modernize or Die: Bio-Engineered Food

China is betting that CRISP technology*can transform the country’s food supply.  China also expanded its efforts beyond its borders in 2017, when the state-owned company ChemChina bought Switzerland-based Syngenta—one of the world’s four largest agribusinesses, which has a large R&D team working with CRISPR—for $43 billion. That was the most China has ever spent on acquiring a foreign company, and it created an intimate relationship between government, industry, and academia—a “sort of a ménage à trois” that ultimately could funnel intellectual property from university labs into the company, says plant geneticist Zachary Lippman of Cold Spring Harbor Laboratory in New York.

Chinese leaders “want to strategically invest in genome editing, and [by that] I mean, catch up,” says Zhang Bei, who heads a team of 50 scientists at the Syngenta Beijing Innovation Center…China may one day need CRISPR-modified plants to provide enough food for its massive population….    China needs to resolve how it will regulate CRISPR-engineered crops—a divisive issue in many countries. In a 2018 decision that rocked big agriculture, a European court ruled that such crops are genetically modified organisms (GMOs) that need strict regulation. In contrast, the U.S. Department of Agriculture (USDA) exempts genome-edited plants from regulations covering GMOs as long as they were produced not by transferring DNA from other species, but by inducing mutations that could have occurred naturally or through conventional breeding.  Chinese consumers are wary of GM food. The country strictly limits the import of GM crops, and the only GM food it grows are papayas for domestic consumption. But for CRISPR, many plant researchers around assume China will follow in the United States’s footsteps…

For Corteva, Syngenta, and the other two big ag companies—BASF and Bayer (which acquired Monsanto last year)—the long game is to use CRISPR to develop better versions of their serious moneymakers, the “elite” varieties of a wide range of crops that have big commercial markets. They sell dozens of kinds of elite corn seeds—for example, inbred strains that consistently have high yields or reliable resistance to herbicides. Creating the genetic purity needed for an elite variety typically takes traditional breeding of many generations of plants, and CRISPR is seen as the cleanest way to improve them quickly. The earlier methods of engineering a plant can lead to unwanted genomic changes that must be laboriously culled…

Syngenta sees CRISPR-modified corn as a big opportunity in China, which grows more hectares of corn than any other crop. Yields per hectare are only 60% of those in the United States because corn ear worms often weaken Chinese crops. A fungus thrives in the weakened plants, producing a toxin that makes the resultant ears unfit for animal feed. As a result, China must import a great deal of corn. (According to USDA, 82% of U.S.-grown corn has been engineered to have a bacterial gene that makes it resistant to ear worms.)…“Syngenta is putting a lot of emphasis to grow in China to become the leading seed company. The China market as a whole, if it modernizes as the U.S. has modernized, can be as big as the U.S. market.”

* Genome editing (also called gene editing) is a group of technologies that give scientists the ability to change an organism’s DNA. These technologies allow genetic material to be added, removed, or altered at particular locations in the genome. Several approaches to genome editing have been developed. A recent one is known as CRISPR-Cas9.

Forest Fires in Africa Feed the Amazon Rainforest

The world’s largest rainforest and a crucial store of carbon dioxide gets most of its phosphorous, an important nutrient, from an unexpected source: fires in Africa.  Strange as it may seem, we thought that the Amazon got much of its phosphorus from dust whipped up from the Sahara Desert and transported across the Atlantic on the wind.

Cassandra Gaston at the University of Miami, US, and her colleagues had set out to quantify the effect of the phosphorous in Saharan dust on the Amazon’s growth. To do this, they collected and analysed particles caught in filters from a hilltop in French Guiana, at the northern edge of the Amazon Basin. But at the same time, they used satellites to track smoke from fires in Africa — both people burning wood and natural forest fires — drifting Westwards across the ocean. It turned out that the arrival of patches of smoke coincided with high levels of phosphorous being detected in the filters.  Gaston and her team then estimated how much of the phosphorus deposited on the Amazon Basin comes from African biomass burning. They found that, in Spring, smoke from the fires was responsible for most of the nutrient entering the Amazon Basin. …The findings suggest that people burning wood and other materials in Africa might have an impact on how much the Amazon grows and therefore how much carbon it stores in future.

Who to Save? Forests or Farmers

Agriculture continues to present the biggest threat to forests worldwide. Some experts predict that crop production needs to be doubled by 2050 to feed the world at the current pace of population growth and dietary changes toward higher meat and dairy consumption. Scientists generally agree that productivity increase alone is not going to do the trick. Cropland expansion will be needed, most likely at the expense of large swathes of tropical forests – as much as 200 million hectares by some estimates. 

Nowhere is this competition for land between forests and agriculture more acute than in Africa. Its deforestation rate has surpassed those of Latin America and Southeast Asia. Sadly, the pace shows no sign of slowing down. Africa’s agriculture sector needs to feed its burgeoning populations- the fastest growing in the world…. What’s more, for the millions of unemployed African youth, a vibrant agriculture sector will deliver jobs and spur structural transformation of the rural economy. Taken together, the pressures on forests are immense. Unless interventions are made urgently, a large portion of Africa’s forests will be lost in the coming decades – one farm plot at a time.

The difficult question is: what interventions can protect forests and support farmers at the same time? 

To tackle these complex challenges, the Center for International Forestry Research (CIFOR) has launched a new initiative: The “Governing Multifunctional Landscapes (GML) in Sub-Saharan Africa: Managing Trade-Offs Between Social and Ecological Impacts”  Read more

How to Kill the Tsetse Fly: Use Nuclear Energy

The tsetse fly’s toxic bite kills an estimated 3 million livestock annually in sub-Saharan Africa.  Farmers here used to count on losing pounds of valuable beef to the fingernail-size pest. Then veterinarians in the West African country teamed up with researchers in Austria, who work on a little-known project funded entirely by the United States.  The United States has poured about $5 million into the effort of sterilizing the male tsetse files with gamma rays.   This has led to the eradication of 99 percent of those files

Cows, Senegale. (source IAEA)

Farmer income in Niayes, Senegale,  is expected to jump by 30 percent, officials say, as more cows survive at a healthy weight. Farms, meanwhile, can now afford to buy hundreds of European dairy cows, which produce 20 times as much milkthan native breeds.  The fortune reversal sprouts from a global collaboration at the intersection of agriculture and nuclear technology

Since 2010, America has funneled roughly $379 million to Senegal’s partner in the tsetse fly fight: the International Atomic Energy Agency,…The United States earmarked an additional $560,000 this month for upkeep of the group’s laboratories in Seibersdorf, Austria.

Rather, Jeffrey Eberhardt, whom President Trump has nominated to serve as his special representative for nuclear nonproliferation, said in a May statement that the United States has maintained its backing to “expand the benefits of peaceful nuclear uses” and expressed “a firm commitment to continuing this legacy.”

The peaceful use in Senegal is called nuclear insect sterilization.  First, scientists hatch thousands of tsetse flies in an artificial habitat about 870 miles away, in the West African nation of Burkina Faso.   Next, they send the bugs to the lab in Seibersdorf, where researchers place them in tiny ionization chambers and blast them with gamma rays, rendering the males unable to pass on a healthy seed.   Finally, they chill the flies to sleep — broken wings from panicked thrashing would sabotage the mission — before tucking them into biodegradable paper boxes and shipping them to Senegal.

How to Strengthen the Immune System of Plants: biodiversity

In the past 150 years, the concentration of carbon dioxide in the atmosphere has risen from 280 parts per million (ppm) to 410 ppm. For farmers this is mixed news. Any change in familiar weather patterns caused by the atmospheric warming this rise is bringing is bound to be disruptive. But more carbon dioxide means more fuel for photosynthesis and therefore enhanced growth—sometimes by as much as 40%. And for those in temperate zones, rising temperatures may bring milder weather and a longer growing season. (In the tropics the effects are not so likely to be benign.) What is not clear, though, and not much investigated, is how rising CO2 levels will affect the relation between crops and the diseases that affect them…

Plant biology is altered substantially by a range of environmental factors. This makes it difficult to predict what effect a changing climate will have on particular bits of agriculture. Carbon dioxide is a case in point. It enhances growth of many plants but,  it also shifts the defences to favour some types of disease over others.

To make matters even more complicated, evidence is mounting that changes in temperature and water availability also shift plant immune responses. André Velásquez and Sheng Yang He, at Michigan State University, wrote an extensive review on the warfare between plants and diseases in Current Biology in 2018. They noted that though some valuable crops, such as potatoes and rice, experience less disease as moisture levels increase, this is not the case for most plants. High humidity, in general, favours the spread of botanical diseases. The same can be said for temperature—with some diseases, like papaya ringspot virus, thriving in rising temperatures while others, for example potato cyst, are weakened.

The problems are daunting, then, but there is a way to try to solve them… Genes which grant resistance to diseases that might become severe in the future need to be tracked down. Modern crops have been streamlined by artificial selection to be excellent at growing today. This means that they have the genes they need to flourish when faced with the challenges expected from current conditions, but nothing more. Such crops are thus vulnerable to changes in their environment.  One way to find genes that may alter this state of affairs is to look to crops’ wild relatives. Uncossetted by farmers, these plants must survive disease by themselves—and have been fitted out by evolution with genes to do so. Borrowing their dna makes sense. But that means collecting and cataloguing them. This is being done, but not fast enough. The International Centre for Tropical Agriculture, a charity which works in the area, reckons that about 30% of the wild relatives of modern crops are unrepresented in gene banks, and almost all of the rest are underrepresented….

[This is becuase] most countries are, rightly, protective of their genetic patrimony. If money is to be made by incorporating genes from their plants into crops, they want to have a share of it. It is therefore incumbent on rich countries to abide by rules that enable poor ones to participate in seed collecting without losing out financially. Poor, plant-rich countries are in any case those whose farmers are most likely to be hurt by global warming. It would be ironic if that were made worse because genes from those countries’ plants were unavailable to future-proof the world’s crops.

5,000 Eyes in the Sky: environmental monitoring

The most advanced satellite to ever launch from Africa will soon be patrolling South Africa’s coastal waters to crack down on oil spills and illegal dumping.  Data from another satellite, this one collecting images from the Texas portion of a sprawling oil and gas region known as the Permian Basin, recently delivered shocking news: Operators there are burning off nearly twice as much natural gas as they’ve been reporting to state officials.

With some 5,000 satellites now orbiting our planet on any given day…. They will help create a constantly innovating industry that will revolutionize environmental monitoring of our planet and hold polluters accountable…

A recent study by Environmental Defense Fund focused on natural gas flares from the wells in the Permian Basin, located in Western Texas and southeastern New Mexico. Our analysis proved that the region’s pollution problem was much larger than companies had revealed.  A second study about offshore gas flaring in the Gulf of Mexico, published by a group of scientists in the Geophysical Research Letters, showed that operators there burn off a whopping 40% of the natural gas they produce.

Soon a new satellite will be launching that is specifically designed not just to locate, but accurately measure methane emissions from human-made sources, starting with the global oil and gas industry.  MethaneSAT, a new EDF affiliate unveiled in 2018, will launch a future where sensors in space will find and measure pollution that today goes undetected. This compact orbital platform will map and quantify methane emissions from oil and gas operations almost anywhere on the planet at least weekly.

Biodiversity and Respect for Human Rights

The instinctive response of many environmentalists  is to to fence off protected areas as rapidly and extensively as possible. That thought certainly dominates discussions of the Convention on Biological Diversity, the main relevant international treaty. An eight-year-old addendum to the pact calls for 17% of the world’s land surface and 10% of the ocean’s water column (that is, the water under 10% of the ocean’s surface) to be protected by 2020. Currently, those figures are 15% and 6%. Campaigners want the next set of targets, now under discussion, to aim for 30% by 2030—and even 50% by 2050. This last goal, biogeographers estimate, would preserve 85% of life’s richness in the long run.  As rallying cries go, “Nature needs half” has a ring to it, but not one that sounds so tuneful in the poor countries where much of the rhetorically required half will have to be found. Many people in such places already feel Cornered by Protected Areas.” (See also Biodiversity and Human Rights)

James Watson, chief scientist at the Wildlife Conservation Society (wcs), another American charity, has an additional worry about focusing on the fence-it-off approach. If you care about the presence of species rather than the absence of humans, he warns, “‘nature needs half’ could be a catastrophe—if you get the wrong half.” Many terrestrial protected areas are places that are mountainous or desert or both. Expanding them may not translate into saving more species. Moreover, in 2009 Lucas Joppa and Alexander Pfaff, both then at Duke University in North Carolina, showed that protected areas disproportionately occupy land that could well be fine even had it been left unprotected: agriculture-unfriendly slopes, areas remote from transport links or human settlements, and so on. Cordoning off more such places may have little practical effect.

 In the United States it is the underprotected southern Appalachians, in the south-east of the country, that harbour the main biodiversity hotspots. The largest patches of ring-fenced wilderness, however, sit in the spectacular but barren mountain ranges of the west and north-west. In Brazil, the world’s most speciose country, the principal hotspots are not, as might naively be assumed, in the vast expanse of the Amazon basin, but rather in the few remaining patches of Atlantic rainforest that hug the south-eastern coast.

Nor is speciosity the only consideration. So is risk-spreading. A team from the University of Queensland, in Australia, led by Ove Hoegh-Guldberg, has used a piece of financial mathematics called modern portfolio theory to select 50 coral reefs around the world as suitable, collectively, for preservation. Just as asset managers pick uncorrelated stocks and bonds in order to spread risk, Dr Hoegh-Guldberg and his colleagues picked reefs that have different exposures to rising water temperatures, wave damage from cyclones and so on. The resulting portfolio includes reefs in northern Sumatra and the southern Red Sea that have not previously registered on conservationists’ radar screens…

Another common finding—counterintuitive to those who take the “fence-it-all-off” approach—is that a mixed economy of conservation and exploitation can work. For example, rates of deforestation in a partly protected region of Peru, the Alto Mayo, declined by 78% between 2011 and 2017, even as coffee production increased from 20 tonnes a year to 500 tonnes.

Environmental groups can also draw on a growing body of academic research into the effective stewardship of particular species. For too long, says William Sutherland, of Cambridge University, conservationists have relied on gut feelings. Fed up with his fellow practitioners’ confident but unsubstantiated claims about their methods, and inspired by the idea of “evidence-based medicine”, he launched, in 2004, an online repository of relevant peer-reviewed literature called Conservation Evidence.  Today this repository contains more than 5,400 summaries of documented interventions. These are rated for effectiveness, certainty and harms. Want to conserve bird life threatened by farming, for example? The repository lists 27 interventions, ranging from leaving a mixture of seed for wild birds to peck (highly beneficial, based on 41 studies of various species in different countries) to marking bird nests during harvest (likely to be harmful or ineffective, based on a single study of lapwing in the Netherlands). The book version of their compendium, “What Works in Conservation”, runs to 662 pages. It has been downloaded 35,000 times.

Who is Afraid of Bats?

More than 50,000 of the fruit bats are thought to have been killed in Mauritius since 2015, in an attempt to protect fruit in orchards.  The bats – also known as flying foxes – are resorting to eating in orchards to survive because only 5 per cent of Mauritius’s native forests remain, animal experts warned.  Fruit bats are vital for biodiversity as they pollinate flowers and scatter seeds, enabling trees and plants to grow and spread, according to conservationists.  But populations of the flying foxes have fallen by more than 50 per cent in four years, said Vincent Florens, an ecologist at the University of Mauritius. Some believe fewer than 30,000 now remain.

The first cull, in 2015, killed 30,000, and in a second cull, the following year, 7,380 were targeted.  The latest cull involved 13,000.  Prof Florens said he believed the number killed is much higher than the 50,300 government figure.  “The culls took place late in the year, when many mothers were pregnant or had babies,” he told National Geographic. “You shoot one bat and basically kill two.” Others were likely to have been injured and died later, he said.

Scientists are supporting a lawsuit against the government on grounds of animal welfare violations to prevent any more culls…Mahen Seeruttun, Mauritius’s minister of agro-industry and food security, told FDI Spotlight: “We have a large population of bats who will eat fruit crops.

From Savior to Villain: Biofuel from Palm Oil

Globally, average palm oil yields have been more or less stagnant for the last 20  years, so the required increase in palm oil production to meet the  growing demand for biofuels  has come from deforestation and peat destruction in Indonesia.  Without fundamental changes in governance, we can expect at least a third of new palm oil  area to require peat drainage, and a half to result in deforestation.

Currently, biofuel policy results in 10.7  million tonnes of palm oil demand.  If the current biofuel policy continues we expect by 2030:
• 67 million tonnes palm oil demand due to biofuel policy.
• 4.5 million hectares deforestation.
• 2.9 million hectares peat loss.
• 7 billion tonnes of CO2 emissions over 20 years, more than total annual U.S. GHG emissions.
It must always be remembered that the primary purpose of biofuel policy in the EU and many  other countries is climate change mitigation. Fuel consumers in the European Union, Norway  and elsewhere cannot be asked to continue indefinitely to pay to support vegetable oil based
alternative fuels
that exacerbate rather than mitigate climate change.

The use of palm oil-based biofuel should be  reduced and ideally phased out entirely.  In Europe, the use of biodiesel other than that produced from approved waste or  by-product feedstocks should be reduced or eliminated.
In the United States, palm oil biodiesel should continue to be restricted from generating  advanced RINs under the Renewable Fuel Standard. Indonesia should reassess the relationship between biofuel mandate, and its  international climate commitments, and refocus its biofuel programme on advanced biofuels from wastes and residues. The aviation industry should focus on the development of advanced aviation biofuels  from wastes and residues, rather than hydrotreated fats and oils.

Excerpts from Dr Chris Malins,  Driving deforestation: The impact of expanding palm oil demand through biofuel policy, January 2018

In Feb. 28, 2019, Norway’s $1 trillion sovereign wealth fund, the world’s largest, pulled out of more than 33 palm oil companies over deforestation risks.

How Nuclear Technology Creates New Plants

Joining the FAO/IAEA coordinated research projects in the area of mutation breeding has led to the development of several barley mutant lines with improved yield and quality under Kuwait’s environmental conditions.  As arable land is limited to small areas, 95% of the country’s food and animal fodder is imported. Barley is a preferred crop for cultivation, because it is relatively drought tolerant and therefore one of the most suitable crops for an arid country like Kuwait. Having high yielding home grown crops is among the key objectives of the country’s agricultural programme to enhance food security.

Drought, salinity and diseases have historically limited staple crop productivity in Kuwait.   Mutation induction by radiation rapidly increases the genetic diversity necessary to produce new and improved varieties and is thus advantageous over traditional breeding…The best adaptable varieties were identified, and the seeds were subjected to induced mutation using gamma rays.

New mutant lines have been generated and they are now examined for drought and salinity tolerance. The selected mutant lines will be advanced, which then can be multiplied for planting. …One of the major challenges was explaining to farmers the safety of the new mutated barley lines developed. “When they heard that ‘nuclear techniques’ were used to create improved barely seeds, they got scared….

Radical New Potatoes

Potatoes are already a staple for 1.3 billion people… but unlike other major crops, however, the potato has not had a breeding breakthrough of the kind that helped dramatically boost yields during the Green Revolution of the 1950s and 1960s. The reason is that creating a new potato variety is slow and difficult, even by the patient standards of plant breeders…Readying a new potato variety for farm fields can take a decade or more.  Many countries continue to plant popular potato varieties that have remained essentially unchanged for decades. But new approaches, including genetic engineering, promise to add more options. Potato breeders are particularly excited about a radical new way of creating better varieties. This system, called hybrid diploid breeding, could cut the time required by more than half, make it easier to combine traits in one variety, and allow farmers to plant seeds instead of bulky chunks of tuber

Solynta Hybrid Potato Seeds

To breed a better potato, it helps to have plenty of genetic raw material on hand. But the world’s gene banks aren’t fully stocked with the richest source of valuable genes: the 107 potato species that grow in the wild. Habitat loss threatens many populations of those plants. In a bid to preserve that wild diversity before it vanishes, collectors have made their biggest push ever, part of a $50 million program coordinated by the Crop Trust, an intergovernmental organization based in Bonn, Germany.

The Crop Trust has provided grants and training to collectors around the world. The effort on wild potatoes, which wraps up this month, has yielded a collection representing 39 species from six nations: Peru, Brazil, Ecuador, Guatemala, Costa Rica, and Chile. Zorrilla’s team alone found 31 species in Peru, including one for which no seeds had ever been collected. They plan to continue to search for four other species still missing from gene banks. “We will not stop,” she says. The plants are being stored in each nation’s gene bank, CIP, and the Millennium Seed Bank at the Royal Botanic Gardens, Kew, in the United Kingdom. The stored seeds will be available to potato breeders worldwide.

THE HARDEST PART comes next: getting desirable genes from wild species into cultivated potatoes….Other researchers are skirting the limitations of traditional breeding by using genetic engineering. CIP’s Marc Ghislain and colleagues, for example, have directly added genes to already successful potato varieties without altering the plants in any other way—an approach not possible with traditional breeding. They took three genes for resistance to late blight from wild relatives and added them to varieties of potato popular in East Africa.

Potato Blight , a disease affecting potatoes

The engineered varieties have proved successful in 3 years of field tests in Uganda and are undergoing final studies for regulators. Transgenic potatoes that resist late blight have already been commercialized in the United States and Canada….

Pim Lindhout has been plotting a revolution that would do away with much of that tedium and complexity. As head of R&D for Solynta, a startup company founded in 2006, he and his colleagues have been developing a new way to breed potatoes….Breeders reduce the complexity either by using species with only two sets of chromosomes (known as diploids) or by manipulating domesticated potatoes to cut the number of chromosomes in half. With persistence, diploid potatoes can be inbred. In 2011, Lindhout published the first report of inbred diploid lines that are vigorous and productive. More recently, Jansky and colleagues also created inbred diploid lines.

Such diploid inbred plants are at the heart of Solynta’s strategy to revolutionize potato breeding. Other firms, including large seed companies, are also working to develop hybrid potatoes. HZPC in Joure, the Netherlands, has begun field trials in Tanzania and in several countries in Asia.

Can Gucci Save the Steppes of Mongolia?

 Essential to the identity and economy of Mongolia—more than half of the country’s 3 million people live there—the grasslands are under increasing threat from overgrazing and climate change. Multiple studies over the past decade have shown that the once lush Mongolian steppe, an expanse twice the size of Texas that is one of the world’s largest remaining grasslands, is slowly turning into a desert. An estimated 70% of all the grazing lands in the country are considered degraded to some degree…. 

The collective here of a little more than 100 families is at the center of an unusual effort, run by the Wildlife Conservation Society (WCS), to turn space-based maps of the grasslands into a tool for making grazing more sustainable. Supported by the world’s largest mining company and a luxury apparel giant, the pilot effort uses data gathered by NASA and Stanford University in Palo Alto, California, to help herders find places where the vegetation is healthy enough to sustain their voracious herds.

 Meanwhile, development, especially mining, has exponentially increased water usage. Twelve percent of rivers and 21% of lakes have dried up entirely. An increasing number of people, vehicles, and heavy equipment put additional stress on the land.  But one factor stands out: overgrazing, which, according to a 2013 study by researchers at Oregon State University in Corvallis, has caused 80% of the recent decline in vegetation on the grasslands.

Mongolia is now the world’s second-largest cashmere producer, after China. Goats, which account for more than half of all grazing animals on the grasslands, can be more lucrative than other livestock, but they’re also much more destructive than the sheep they’ve replaced because they eat roots and the flowers that seed new grasses=s.

WCS’s Sustainable Cashmere project may offer part of the solution. The project, whose budget the organizers won’t disclose, is funded by mining giant Rio Tinto, which runs a massive copper mine not far away, and Kering, the French luxury apparel giant that owns Gucci, Balenciaga, and other brands that need cashmere. Both aim to help offset their impact on the Mongolian environment, a requirement of Rio’s mining agreement and part of Kering’s corporate social responsibility program.

How to Kill One Million Fish: Murray-Darling

But it took a viral video posted on 8 January 2019 to drive home the ecological catastrophe that was unfolding in the Murray-Darling river system in Australia. In the footage, Rob McBride and Dick Arnold, identified as local residents, stand knee-deep among floating fish carcasses in the Darling River, near the town of Menindee. They scoff at authorities’ claims that the fish die-off is a result of the drought. Holding up an enormous, dead Murray cod, a freshwater predator he says is 100 years old, McBride says: “This has nothing to do with drought, this is a manmade disaster.” Arnold, sputtering with rage, adds: “You have to be bloody disgusted with yourselves, you politicians and cotton growers.”

Scientists say McBride probably overestimated the age of the fish. But they agree that the massive die-off was not the result of drought. “It’s about taking too much water upstream [to irrigate farms] so there is not enough for downstream users and the fish,” says Quentin Grafton, an economist specializing in water issues at Australian National University (ANU) in Canberra. The Australia Institute, a Canberra-based think tank, blamed “policy failure and mismanagement” in a 19 January 2019 report, but called drought a catalyst.

Excessive water use has left river flows too low to flush nutrients from farm runoff through the system, leading to large algal blooms, researchers say. A cold snap then killed the blooms, and bacteria feeding on the dead algae sucked oxygen out of the water,   This wasn’t supposed to happen. In 2012, the national government adopted the Murray-Darling Basin Plan, touted as a “historic” deal to ensure that enough water remained in the rivers to keep the ecosystem healthy even after farmers and households took their share.

In 2008, the federal government created the Murray-Darling Basin Authority to wrestle with the problem. In 2010, a study commissioned by the authority concluded that farmers and consumers would have to cut their use of river water by at least 3000 but preferably by 7600 gigaliters annually to ensure the health of the ecosystem. Farmers, who saw their livelihoods threatened, tossed the report into bonfires.  The final plan, adopted as national law in 2012, called for returning just 2750 gigaliters to the rivers, in part by buying water rights back from users. “It was a political compromise that has never been scientifically reviewed,” Williams says, adding that “climate change was never considered in the plan, which was a dreadful oversight.”..

Grafton says there are also suspicions of widespread water theft; up to 75% of the water taken by irrigators in the northern part of the system is not metered. Farmers are also now recapturing the runoff from irrigated fields that used to flow back into streams, and are increasing their use of ground water, leaving even less water in the system, says Mike Young, an environmental policy specialist at the University of Adelaide in Australia.

In February 2018, such issues prompted a group of 12 academics, including scientists and policy experts, to issue the Murray-Darling Declaration. It called for independent economic and scientific audits of completed and planned water recovery schemes to determine their effects on stream flows. The group, which included Williams and Grafton, also urged the creation of an independent, expert body to provide advice on basin water management. Young, who wasn’t on the declaration, wants to go further and give that body the power to manage the basin’s water, the way central banks manage a country’s money supply, using stream levels to determine weekly irrigation allocations and to set minimum flow levels for every river.

How to Discover an Illegal Logger

Tropical forests nearly the size of India are set to be destroyed by 2050 if current trends continue causing species loss, displacement and a major increase in climate-changing greenhouse gas emissions.  Prior to the launch of the Global Land Analysis and Discovery (GLAD) alerts, researchers would have to manually track images of logging in specific areas.

The new process, developed by scientists at the University of Maryland and Google, uses an algorithm to analyze weekly updates of satellite images and sends automatic notifications about new logging activity.”This is a game changer,” said Matt Finer from the Amazon Conservation Association, an environmental group.

His organization tracks illegal logging in Peru, sending images of deforestation to policymakers, environmentalists and government officials to try and protect the Amazon rainforest.  In the past, he would rely on tips from local people about encroachment by loggers, then look at older satellite images to try and corroborate the claims.

“With this new data we can focus on getting actionable information to policy makers,” Finer told the Thomson Reuters Foundation.  “We have seen how powerful these images can be,” he said, citing a case where his group brought pictures of illegal gold miners cutting down trees to the Peruvian government, who then removed the miners.

Caring for the Third Pole

The Tibetan Plateau and its surrounding mountains [the Himalayas], often termed the Third Pole, contain more ice than anywhere outside the Arctic and Antarctic. This region is also the source of the nine largest rivers in Asia, providing fresh water, food, and other ecosystem services to more than 1.5 billion people…In recent decades, air temperature at the Third Pole has warmed significantly faster than the global average…Meanwhile, intensive anthropogenic activities, such as overgrazing, deforestation, urbanization, and expansion of infrastructure projects such as construction of roads, dams, and electrical grids, are causing widespread landcover changes within the region.

Together, these changes are altering the Third Pole’s biogeochemical cycles and pushing the fragile ecosystem toward degradation and possible collapse, which would cause irreversible harm on a regional and global scale. To avoid this, all nations must meet the standards laid out in the Paris Agreement. At the regional level, we strongly urge the relevant nations (including Afghanistan, Bhutan, China, India, Kyrgyzstan, Myanmar, Nepal, Pakistan, and Tajikistan) to cooperate in addressing these impending threats through systematic changes to management policies. Rapid and unprecedented coordination will be necessary, including a regional cooperation treaty and formation of a cross-border biodiversity conservation plan for the Third Pole region. Meanwhile, any infrastructure projects undertaken must be environmentally sustainable, and a practicable grazing management policy should be adopted.

Making a Fortune from Climate Change

Eleven years ago Dharsono Hartono, a former JPMorgan Chase & Co. banker, spotted what he thought was a new way to make a fortune: climate change.The plan was to snap up rainforest in Borneo, preserve it from logging and sell carbon credits to big polluting companies in the developed world. The earth’s temperature was rising, and this was a way to profit by confronting the problem.  Investors around the world have poured money into assets like once-frozen farmland in Canada and groundwater basins in California, betting that warming temperatures will raise their value.  Another bet has been on what some investors hope will be the most profitable outcome of a warming climate: government regulation of carbon emissions. Those who correctly anticipate future government responses to climate change are likely to reap profits.

Mr. Hartono went in big. His company’s rain forest, a humid and swampy expanse home to orangutans and clouded leopards, is twice the size of New York City and has one of the largest carbon stores of any such project in the world.  Mr. Hartono has sold just 20% of his credits to environmentally conscious corporations voluntarily buying credits, and has lost around $20 million, burning through $5 million to $10 million a year in recent years. Other investors in Indonesia and Latin America who made similar bets, including one backed by Australian bank Macquarie Group , failed to sell credits and abandoned their rain-forest projects…

Only after actor Harrison Ford visited the project to shoot a documentary on climate change, and raised the issue with Indonesia’s forestry minister, did final approval come for most of the concession in October 2013. For an initial payment of around $3 million to the Indonesian government, Mr. Hartono’s company gained the rights to the forestland for 60 years.  By then, however, some environmentalists were questioning private carbon-selling projects like Mr. Hartono’s. They argued that buying up and preserving rain forest to sell credits wouldn’t decrease net deforestation, since palm-oil barons would simply work around the few protected plots in the forest.  U.S. legislation that would have put a price on carbon failed during the Obama administration. The European Union’s carbon market doesn’t include tropical forests amid worry that low-cost credits generated there would make it affordable to pollute…

The Paris climate accords are expected to lead to an international carbon market after 2020, where countries that exceed emissions targets can purchase offset credits from countries that reduce emissions beyond their targets, potentially opening up new opportunities for Mr. Hartono.

A Botanical Treasure: Congo

Situated along the banks of the Congo River, the Yangambi Research Station was in its heyday a booming scientific hub, revered for its invaluable work in the Congo Basin throughout the midcentury.

It wasn’t to last. War, political instability and budget cuts were to hamper the center’s survival after Democratic Republic of Congo (DRC) gained independence from its colonial ruler, Belgium, in 1960. The following decades would see skilled staff numbers dwindle, the jungle reclaim its buildings, and the center’s science work come to a stop.  But inside these crumbling walls lay a botanical treasure-trove. Yangambi’s herbarium holds Central Africa’s largest collection of dried plants. In fact, 15% of its 150,000 specimens are so rare, that they can only be found here….

Efforts from the Congolese Institute for Agronomy Research (INERA) could not keep the center running alone.   It was in 2017 that a ‘game changing’ opportunity arrived. INERA and the Meise Botanic Garden partnered with FORETS, a project coordinated by the Center for International Forestry Research (CIFOR)and financed by the European Union…Now, the herbarium has benefitted from a facelift – including a new roof, windows and doors, and a water cistern – soon its staff will be trained in modern preservation techniques and new technologies…Digitization of specimens will enable access to researchers around the world.

Who to Blame for Climate Change? the Carbon Majors

 Whether the damage caused by extreme weather events can be linked to human emissions of greenhouse gases is one of the hottest topics in climate science. And that debate leads directly to another: if this link can be established, who bears the responsibility?  Both of these questions are at the center of an inquiry by the Philippine Commission on Human Rights, whose latest hearings took place in London in November 2018. It is the first time a human-rights commission has heard evidence on whether large emitters violate basic human rights by causing climate change

 Where the hearings become more unusual is in investigating the link between the damage caused by climate change and the behaviour of large industrial companies. This is predicated on recent efforts to trace greenhouse-gas emissions back to large corporate and state-owned producers of fossil fuels and cement, dubbed the “carbon majors”. The latest analysis by cdp (formerly the  Carbon Disclosure Project), a non-governmental organisation that works with companies, cities and states to measure their environmental impact, published in 2017, found that 100 of them had produced just over half of emissions since the Industrial Revolution.

The Philippine hearings will come to a close in December in Manila. The commission does not have the power to compensate victims of typhoons or to sanction emitters of carbon dioxide. According to Roberto Cadiz, one of the commissioners, that isn’t even the point. His wish is to open a dialogue about possible solutions to climate change that includes the industrial emitters. So far, however, only one side of the story is being heard. The emitters have declined to participate.

Genetically Modified Crops in Africa: opponents

According to the acting director, Andrew Kigundu,  of Uganda’s National Agricultural Research Organisation (NARO): “The idea of work on genetically engineered bananas is a result of many years of testing of Banana production.” The experiments started in 2005 and work is still ongoing to improve on the content of the fruit and resistance to parasites….The East African country is the first African country to turn toward GM to improve its production of bananas. An option which should make the country remain the first producer in the world .

The adoption of restrictive policies across Africa has been pursued under the pretext of protecting the environment and human health. So far there has been little evidence to support draconian biosafety rules. It is important that the risks of new products be assessed. But the restrictions should proportionate and consistent with needs of different countries.

Africa’s needs are different from those of the EU. There are certain uniquely African problems where GM should be considered as an option.   The Xanthomonas banana wilt bacterial disease causes early ripening and discoloration of bananas, a staple crop for Uganda. This costs the Great Lakes region nearly US $500m annually in losses. There is no treatment for the disease, which continues to undermine food security.  Ugandan scientists at Kawanda Agricultural Research Institute have developed a GM approach but their efforts to further their research in the technology are hampered by opposition to it. Those opposed to the technology advocate the adoption of an EU biosafety approach that would effectively stall the adoption of the technology. In fact, some of opponents using scare tactics against the technology are EU-based non-governmental organizations.

Genetically modified bananas solve Uganda’s productivity problems, AllAfricanews, May 24, 2016; See also Excerpt FromHow the EU starves Africa into submission,” by Calestous Juma, a professor of the practice of international development at the Harvard Kennedy School of Government:  “EU policy undermines African agricultural innovation …in the field of genetically modified (GM) crops. The EU exercises its right not to cultivate transgenic crops but only to import them as animal feed. However, its export of restrictive policies on GM crops has negatively affected Africa.”

How to Stop the Chemical Wars of the Future

Stark illustrations of the dangers from chemical weapons can be seen in attacks using toxic industrial chemicals and sarin against civilians and combatants in Syria and toxic industrial chemicals in Iraq, as well as more targeted assassination operations in Malaysia and the United Kingdom, employing VX and novichok nerve agents, respectively. . With the parties to the Chemical Weapons Convention (CWC) convening a Review Conference to address such issues beginning 21 November 2018, we highlight important scientific aspects .

The Chemical Weapons Convention (CWC) is a multilateral treaty in effect since 1997 that proscribes the development, production, stockpiling, transfer, and use of chemical weapons “under any circumstances” and requires their destruction within a specified time period. The CWC allows the use of toxic chemicals for a range of industrial, agricultural, research, medical, pharmaceutical, or other peaceful purposes, including law enforcement, as long as the “types and quantities” of chemicals employed are “consistent with such purposes.” …The Organisation for the Prohibition of Chemical Weapons (OPCW), which is the implementing body of the CWC, comprises the 193 State Parties and a Technical Secretariat that provides technical assistance to States, routinely inspects relevant State and commercial industrial facilities, and monitors activities to ensure compliance. It was awarded the Nobel Peace Prize in 2013 for overseeing and facilitating the verified destruction of most of the declared chemical weapons stocks produced in the last century—to date totaling more than 96% (69,750 metric tons) of the declared stockpiles of chemical agents.

Although the CWC includes three schedules of toxic chemicals for the application of verification measures, the scope of the CWC is not constrained to these schedules but by its General Purpose Criterion (GPC), which prohibits misuse of toxic chemicals based on intent rather than on this limited list of chemicals.  [This GPC makes it possible to widen the authority of the OPCW. More, specifically issues to consider include]:

1) Riot control agents (RCAs). The CWC defines RCAs—such as tear gas and pepper spray—as “any chemical not listed” in one of its three schedules that can produce “rapidly in humans sensory irritation or disabling physical effects which disappear within a short time following termination of exposure.”…However, a recurring concern documented by the medical community and human rights monitors has been the widespread misuse of RCAs by police and security forces in excessive quantities, including in hospitals, prisons, homes, and automobiles, where targeted individuals cannot disperse. In such situations, serious injury or death can result from toxic properties of chemicals or from asphyxiation… [It is important to clarify] the nature and scope of “law enforcement” activities and develop guidance as to “types and quantities” of RCAs that can legitimately be used in such circumstances

2) Delivery systems… capable of delivering far greater amounts of RCAs (and potentially other toxic chemicals) over wider areas or more extended distances than current standard law enforcement delivery mechanisms, such as handheld sprays, grenades, and single launched projectiles. Such new systems include large-capacity spraying devices, automatic grenade launchers, multibarrel projectile launchers, large-caliber RCA projectiles, and unmanned ground or aerial vehicles capable of carrying spraying devices or projectile launchers. ..

3) Incapacitating chemical agent (ICA) weapons. Although the CWC permits use of appropriate types and quantities of RCAs for law enforcement, certain countries have conducted research into weapons employing other distinct toxic chemicals, so-called ICAs. Not separately defined under the CWC, ICAs can be considered as a range of toxic chemicals—only one of which [3-quinuclidinyl benzilate (BZ) and two of its immediate precursors] is currently scheduled—including anesthetics and other pharmaceutical chemicals that are purportedly intended to act on the body’s core biochemical and physiological systems, notably the central nervous system (CNS), to cause prolonged but nonpermanent disability. Such CNS-acting chemicals can produce unconsciousness, sedation, hallucination, incoherence, disorientation, or paralysis…An aerosolized mixture of two anesthetics—carfentanil and remifentanil—employed by Russian security forces to end the Moscow theatre siege of October 2002 caused the deaths of 125 of the 900 hostages

Other chemical production facilities (OCPFs) are chemical plants that do not currently produce, but are capable of manufacturing, chemical warfare agents or precursors. At present, a small fraction of declared OCPFs are selected for verification by the OPCW; the Review Conference should consider authorizing a substantial increase in OCPF inspections per year. …Biological and biologically mediated processes for production of discrete organic chemicals  Some products and processes used by the biomanufacturing industry are as relevant to the CWC as those used by other OCPF facilities  The OPCW should  build on the considerable progress made toward developing a network of designated laboratories for the analysis of biomedical and biological samples. Advances in other fields could also facilitate more effective evidence collection, for example, exploring the potential of unmanned aerial vehicles to support reconnaissance, detection, and chain of custody.

Sequencing All Species: the Earth BioGenome Project

In the first attempt of its kind, researchers plan to sequence all known species of eukaryotic life—66,000 species of animals, plants, fungi, and protozoa—in a single country, the United Kingdom. The announcement was made here today at the official launch of an even grander $4.7 billion global effort, called the Earth BioGenome Project (EBP), to sequence the genomes of all of Earth’s known 1.5 million species of eukaryotes within a decade.

In terms of genomes sequenced, the eukaryotes—the branch of complex life consisting of organisms with cells that have a nucleus inside a membrane—lag far behind the bacteria and archaea. Researchers have sequenced just about 3500 eukaryotic genomes, and only 100 at high quality.

The U.K. sequencing effort—dubbed The Darwin Tree of Life project—will now become part of the EBP mix…Also announced today was a memorandum of understanding for participating in EBP. It has been signed by 19 institutions, including BGI Shenzhen, China; the Royal Botanic Gardens, Kew; and Sanger.

Eradicate Mosquitoes Forever: Gene Drives

The mosquitoes are being fitted with a piece of dna called a gene drive. Unlike the genes introduced into run-of-the-mill genetically modified organisms, gene drives do not just sit still once inserted into a chromosome. They actively spread themselves, thereby reaching more and more of the population with each generation. If their effect is damaging, they could in principle wipe out whole species.. If gene drives were to condemn to a similar fate the mosquitoes that spread malaria, a second of humankind’s great scourges might be consigned to history.

Gene drives can in principle be used against any creatures which reproduce sexually with short generations and aren’t too rooted to a single spot. The insects that spread leishmaniasis, Chagas disease, dengue fever, chikungunya, trypanosomiasis and Zika could all be potential targets. So could creatures which harm only humankind’s dominion, not people themselves. Biologists at the University of California, San Diego, have developed a gene-drive system for Drosophila suzukii, an Asian fruitfly which, as an invasive species, damages berry and fruit crops in America and Europe. Island Conservation, an international environmental ngo, thinks gene drives could offer a humane and effective way of reversing the damage done by invasive species such as rats and stoats to native ecosystems in New Zealand and Hawaii.

Such critics fear that the laudable aim of vastly reducing deaths from malaria—which the World Health Organisation puts at 445,000 a year, most of them children—will open the door to the use of gene drives for far less clear-cut benefits in ways that will entrench some interests, such as those of industrial farmers, at the expense of others. They also point to possible military applications: gene drives could in principle make creatures that used not to spread disease more dangerous… The ability to remove species by fiat—in effect, to get them to remove themselves—is, like the prospect of making new species from scratch, a power that goes beyond the past ambit of humankind.

Gene drives based on crispr-Cas9 could easily be engineered to target specific bits of the chromosome and insert themselves seamlessly into the gap, thus ensuring that every gamete gets a copy . By 2016, gene drives had been created in yeast, fruitflies and two species of mosquito. In work published in the journal Nature Biotechnology in September, Andrea Crisanti, Mr Burt and colleagues at Imperial showed that one of their gene drives could drive a small, caged population of the mosquito Anopheles gambiae to extinction—the first time a gene drive had shown itself capable of doing this. The next step is to try this in a larger caged population.

There are also worries about how gene drives might be used to create a weapon. …The need to find ways to guard against such attacks is one of the reasons that the Pentagon’s Defence Advanced Research Projects Agency (darpa) gives for its work on gene drives. Renee Wegrzyn, programme manager for darpa’s “Safe Genes” project, says the work is to prevent “technological surprise”, whether in the form of an unintended consequence or nefarious use. One of the academic teams she funds has made progress in developing anti-crispr enzyme systems that one day might be able to inhibit a drive’s operation.

Oversight needs not just to bring together a range of government agencies; it requires co-operation between governments, too. The Cartagena Protocol on Biosafety, which entered into force under the un Convention on Biological Diversity (cbd) in 2003, provides controls on the transfer of genetically modified organisms. But how it applies to gene drives is unclear—and besides, America has never ratified the convention. An attempt to ban gene-drive research through the cbd, which was backed by the etc Group and other ngos, failed at the convention’s biennial meeting in Cancún in 2016…Like the reintroduction of vanished species advocated by the rewilding movement, gene-drive technology will provide new arenas for the fight between those who wish to defend nature and those who wish to tame it.

Excerpts from Gene Drives: Extinction on Demand, Economist, Nov. 10, 2018, at 24

Meddling with Nature: Is it Right? Is it Fair?

Many envisioned environmental applications of newly developed gene-editing techniques such as CRISPR might provide profound benefits for ecosystems and society. But depending on the type and scale of the edit, gene-edited organisms intentionally released into the environment could also deliver off-target mutations, evolutionary resistance, ecological disturbance, and extinctions. Hence, there are ongoing conversations about the responsible application of CRISPR, especially relative to the limitations of current global governance structures to safeguard its use,   Largely missing from these conversations is attention to local communities in decision-making. Most policy discussions are instead occurring at the national or international level even though local communities will be the first to feel the context-dependent impacts of any release. ..

CRISPR gene editing and other related genetic technologies are groundbreaking in their ability to precisely and inexpensively alter the genome of any species. CRISPR-based gene drives hold particular import because they are designed to rapidly spread genetic changes—including detrimental traits such as infertility—through populations of sexually reproducing organisms, to potentially reach every member of a species. Villages in Burkina Faso are weighing the release of gene drive–bearing mosquitoes that could suppress malaria. Nantucket Island residents in the United States are considering the release of genetically engineered white-footed mice to deplete Lyme disease reservoirs. New Zealand communities are discussing the possibility of using genetic methods to eliminate exotic predators.

But what if a gene drive designed to suppress an invasive species escaped its release site and spread to a native population? Or if a coral species gene edited to better adapt to environmental stressors dominated reef ecosystems at the expense of a diversity of naturally evolving coral species and the fish that depend on them ? The gravity of these potential outcomes begs the question: Should humans even be meddling with the DNA of wild organisms? The absence of generally agreed on answers can be used to support calls for moratoria on developing and releasing genetically altered organisms, especially those with gene drives (6).

However, the promising benefits of environmental gene editing cannot be dismissed. Gene drives may provide a long-sought-after tool to control vectors of infectious disease and save millions of human lives. Projects to conserve ecosystems or promote species resilience are often intended to repair human-inflicted environmental damage. Put simply, either using this technology irresponsibly or not using it at all could prove damaging to humans, our welfare, and our planet.

At the international level, the Convention on Biological Diversity (CBD) has enlisted an expert technical panel to, in part, update its Cartagena Protocol (of which the United States is not a party) that oversees transboundary transport of living modified organisms to accommodate gene drive–bearing organisms. The International Union for the Conservation of Nature (IUCN) is also developing policy to address the release of gene-edited organisms. Although the CBD and the IUCN offer fora to engage diverse public feedback, a role largely fulfilled by civil society groups, none of these agencies currently use the broad and open deliberative process we advocate….

Different societal views about the human relationship to nature will therefore shape decision-making. Local community knowledge and perspectives must therefore be engaged to address these context-dependent, value-based considerations.  A special emphasis on local communities is also a matter of justice because the first and most closely affected individuals deserve a strong voice in the decision-making process…Compounding this challenge is that these decisions cannot be made in isolation. Organisms released into local environments may cross regional and even international borders. Hence, respect for and consideration of local knowledge and value systems are necessary, but insufficient, to anticipate the potentially ramifying global implications of environmental release of gene-edited organisms. What is needed is an approach that places great weight on local perspectives within a larger global vision…

The needs of ecosystems could also be given voice to inform deliberative outcomes through custodial human proxies. Inspired by legislative precedent set by New Zealand, in which the Whanganui River was granted legal “personhood,” human representatives, nominated by both an international body like the IUCN and the local community, would be responsible for upholding the health and interests of the ecosystems in question. Proposed gene-editing strategies would be placed in the larger context of alternative approaches to address the public health or environmental issue in question…

An online registry for all projects intending to release genetically engineered organisms into the environment must be created. Currently, no central database exists for environmental gene-editing applications or for decision-making outcomes associated with their deployment, and this potentially puts the global community at risk…A global coordination task force would be charged with coordinating multiple communities, nations, and regions to ensure successful deliberative outcomes. As a hypothetical example, genetic strategies to eliminate invasive possums from New Zealand must include representatives from Australia, the country likely to be affected should animals be transported outside the intended range. Similarly, the African Union is currently deliberating appropriate governance of gene drive–bearing mosquitoes to combat malaria on a regional scale.

The 500 Cases of Marine Pollution

An international law enforcement operation against maritime pollution has revealed hundreds of violations and exposed serious cases of contamination worldwide.  Codenamed 30 Days at Sea, the month-long (1-31 October) operation saw some 276 law enforcement and environmental agencies across 58 countries detect more than 500 offences, including illegal discharges of oil and garbage from vessels, shipbreaking, breaches of ship emissions regulations, and pollution on rivers and land-based runoff to the sea.  More than 5200 inspections have resulted in at least 185 investigations, with arrests and prosecutions anticipated.

“Criminals believe marine pollution is a low-risk crime with no real victims.  This is a mistake and one which INTERPOL and our partners are addressing as demonstrated by this operation,” said INTERPOL Secretary General Jürgen Stock.  Cases of serious contamination included the dumping of animal farm waste in Philippine coastal waters where local communities collect shellfish and children play.  In Germany, a vessel discharged 600 litres of palm oil into the sea. Ghana uncovered gallons of waste oil in large bottles thought to be illegally dumped at sea.  Authorities prevented an environmental disaster in Albania by securing waters around a sinking vessel containing some 500 litres of oil. Similarly, the pollution threat resulting from the collision of two ships in French waters was contained thanks to preventive action during the operation.

Innovative technologies permitted authorities to detect offences, including the use of satellite images (in Argentina and Sweden), aerial surveillance (Canada and Italy), drones (Nigeria, Indonesia and Pakistan) and night vision cameras.

The Water Barons of Australia

Australia has one of the world’s most sophisticated water-trading systems, and officials in other water-challenged places—notably California and China—are drawing on its experience to manage what the World Bank has called world’s “most precious resource.”  The system here, set up after a catastrophic drought in the 2000s saw the country’s most important river system almost run dry, aims to make sure each gallon of river water goes to higher-value activities.

But the return of severe drought to an area of eastern Australia more than twice the size of Texas is testing the system…Putting a price on water is politically unacceptable in many countries, where access to lakes and rivers is considered a basic right and water is often allocated under administrative rules instead of by markets.

Many water markets that do exist only allow landowners to buy and sell water rights. Australia since 2007 has allowed anyone to trade water parcels, putting supply under the influence of market forces in a system now valued at about $21 billion. Water may be freely bought and sold by irrigators, farmers, water brokers or investors through four exchanges—H2OX, Waterfind, Water Exchange and Ruralco—which allow real-time pricing…

As Australia rewrote the rules of its water market over the last decade to deal with its own drought crises, many farmers chose to sell their water licenses and rely on one-off purchases to keep farming.  The tactic worked until winter rains failed to arrive this year, turning fertile areas into dust bowls. Where a megaliter of water in June last year, before the drought took hold, cost around 3,000 Australian dollars (U.S. $2,166), the price is now closer to A$5,000, according to Aither Water, an advisory firm. The high cost has left smaller farmers praying for rain…

Australia’s drought is splitting agriculture-producing regions into those who have water and those who don’t.  Large investors—including Canadian and U.S. funds—bought high-price water licenses to set up agribusiness ventures in profitable almonds, cotton and citrus, with an eye to growing Asian markets. Others have set up dedicated water investment funds, with prices at the highest levels seen since the drought last decade.

In a country where boom-and-bust cycles, through drought and flood, have historically made water a political flashpoint, some rural Australian lawmakers and farmers want the government to divert water to help parched farms…In August 2018, Victoria state auctioned 20 gigaliters of water that had been earmarked for the environment, putting it on the market for dairy and fruit regions around Cohuna…Some water traders and environmentalists criticized the move as political interference—and said it risked undermining the water market by giving priority to farmers and disrupting forward trades and planning by other irrigators….Euan Friday, a water manager for farm and water investment company Kilter Rural, said the market is doing what it is supposed to do, and warned that the country’s fragile rivers—much smaller than the major rivers of North America—would be facing a dire situation without it. Supported by Australian pension funds, Kilter Rural has invested $130 million in buying water rights and redeveloping farmland.

Cryopreservation of Endangered Species

In paper in 2018 in Nature Plants, researchers at the Royal Botanic Gardens, Kew, detail for the first time the scale of threatened species that are unable to be conserved in seed banks. The paper reveals that when looking at threatened species, 36 per cent of ‘critically endangered species produce recalcitrant seeds . This means they can’t tolerate the drying process and therefore cannot be frozen, the key process they need to go through to be safely ‘banked’.

In the paper, Kew scientist Dr. John Dickie, former Kew scientist Dr. Sarah Wyse, and former Director of Science at Kew Prof. Kathy Willis, found that other threatened categories and global tree species list also contain high proportions of species that are unbankable including 35% of ‘vulnerable’ species, 27% of ‘endangered’ species and 33% of all tree species.

Among these species are important UK heritage trees such as oaks, horse chestnuts and sweet chestnuts, as well as worldwide food staples like avocado, cacao, and mango. This latest research reveals that the scale of plants unable to be conserved in seed banks is much higher for threatened species. The issue is particularly severe for tree species, especially those in tropical moist forests where a half of the canopy tree species can be unsuitable for banking…

Currently, seed banking is the most commonly practiced way of conserving plantsoutside of their natural habitats. Seed banking works as an ‘insurance policy’ against the extinction of plants in the world—especially for those that are rare, endemic and economically important—so that they can be protected and utilised for the future.

[The scientists proposed]cryopreservation—a form of preservation using liquid nitrogen which offers a potential long-term storage solution for recalcitrant seeds. In seed banks, seeds are dried and frozen at -20°C whereas cryopreservation involves removing the embryo from the seed and then using liquid nitrogen to freeze it at a much colder temperature of -196°C…As well as allowing ‘unbankable’ species to be stored, cryopreservation also helps to extend the lifespans of orthodox seeds that otherwise have storage lives that are too short at -20°C.

Insect Biogeneering as a Biological Weapon: DARPA

According to Science Magazine, Agricultural genetic technologies typically achieve their agronomic aims by introducing laboratory-generated modifications into target species’ chromosomes. However, the speed and flexibility of this approach are limited, because modified chromosomes must be vertically inherited from one generation to the next. In an effort to remove this limitation, an ongoing research program funded by the U.S. Defense Advanced Research Projects Agency (DARPA) aims to disperse infectious genetically modified viruses that have been engineered to edit crop chromosomes directly in fields [through insects]. This is genetic engineering through horizontal transfer, as opposed to vertical inheritance. The regulatory, biological, economic, and societal implications of dispersing such horizontal environmental genetic alteration agents (HEGAAs)[eg leafhoppers, whiteflies and aphids) into ecosystems are profound. Further, this program stipulates that the means of delivery of these viral HEGAAs into the environment should be insect-based dispersion (Insect Allies Program). In the context of the stated aims of the DARPA program, it is our opinion that the knowledge to be gained from this program appears very limited in its capacity to enhance U.S. agriculture or respond to national emergencies (in either the short or long term). Furthermore, there has been an absence of adequate discussion regarding the major practical and regulatory impediments toward realizing the projected agricultural benefits. As a result, the program may be widely perceived as an effort to develop biological agents for hostile purposes and their means of delivery, which—if true—would constitute a breach of the Biological Weapons Convention (BWC).

How Rivers Die

Kapuas, Indonesia’s longest river support somes 3m people…One reason that the water is so murky is deforestation. Since the 1970s logging has enriched locals while stripping away the vegetation that held the soil in place. The Centre for International Forestry Research (CIFOR) found that between 1973 and 2010 over 100,000 square kilometres of forest was lost on Kalimantan, or a third of the original coverage. A national moratorium that began in 2011 has done little to still the axes. As a result, torrential tropical rains wash lots of loose earth into the Kapuas.

Illegal gold-mining compounds the problem. Locals tear up the riverbed with diggers or blast the banks with high-pressure hoses, then sieve the mud for gold. Mercury, which the miners use to separate gold from sediment, but which is poisonous to humans and fish alike, leaks into the river.

The riverbank is punctuated with corrugated-iron towers, which emit birdsong from loudspeakers. These are designed to lure swiftlets, who make their nests with saliva. The nests of swiftlets  are considered a delicacy and aphrodisiac by many Chinese.* Deane, a shop owner, built his tower last December after seeing others do the same. He sells the nests to a wholesaler for about 15m rupiah ($1,025) a kilogram…

In Kapuas Hulu, an upstream district, half the population rely on the river for drinking water. A quarter have no toilet. Even where bathrooms do exist along the river, they are often floating cubicles with a hole in the floorboards. Cows and goats, living in wooden riverside cages, also defecate straight into the Kapuas

The Kapuas passes through seven districts. Midstream ones, such as Sintang and Sanggau, earn hefty tax revenues by encouraging palm-oil plantations. But downstream districts suffer from the resulting silt, traffic and run-off without receiving any of the benefits. The same problem occurs at a village level. Mr Hadi says that fishing by sprinkling poisonous leaves on the water (the stricken fish float to the surface) is forbidden but other village heads do not enforce the rules…

A study by CIFOR on the income of villagers living near the Kapuas river found that the best-paid palm-plantation workers earned 50% more than the most successful fishermen. (Gold miners made three times as much—and spent more on education.)…But the environmental damage is plain to see. The river here is brown, clouded by silt. A study published in 2016 found that levels of phosphates in the water, from fertilisers and villagers washing themselves with soap, are highest near urban areas and palm plantations.

Down in Pontianak, the river water is darker still, occasionally brightened by oil slicks. Water bottles and instant-noodle packets cling together to form plastic islands.

Excerpts from  Indonesia’s Longest River,  Economist, Aug. 25, 2018

*According to Wikipedia: Authentic bird’s-nest soup is made from nests of some species of swiftlet.  Instead of twigs, feathers and straw, these swiftlets make their nest only from strands of their gummy saliva, which hardens when exposed to air. Once the nests are harvested, they are cleaned and sold to restaurants. Eating swiftlet nest material is believed to help maintain skin tone, balance qi (“life energy”) and reinforce the immune system… (Dictionary of Traditional Chinese Medicine, The History of Chinese Medicine and the Nutrition Table).

A Gasfield and the Cows Next to it

High levels of a radioactive material and other contaminants have been found in water from a West Australian fracking site* but operators say it could be diluted and fed to beef cattle.  The revelations illustrate the potential risks associated with the contentious gas extraction process known as fracking, or hydraulic fracturing, as the Turnbull government pressures states to ease restrictions on the industry and develop their gas reserves.

The findings were contained in a report by oil and gas company Buru Energy that has not been made public. It shows the company also plans to reinject wastewater underground – a practice that has brought on seismic events when used in the United States.

Buru Energy has been exploring the potentially vast “tight gas” resources of the Kimberly region’s Canning Basin. The work was suspended when the WA government last year introduced a fracking moratorium, subject to the findings of a scientific inquiry.

In a submission to the inquiry obtained by the Lock the Gate Alliance, Buru Energy said a “relatively high concentration” of Radium-228…The samples exceeded drinking water guidelines for radionuclides. However Buru Energy said samples collected from retention ponds were below guideline levels and the water posed “no risk to humans or animals”.  Water monitoring also detected elevated levels of the chemical elements barium, boron and chloride….Buru Energy said while the water was not suitable for human consumption, the “reuse of flowback water for beef cattle may also be considered”.  The water did not meet stockwater guidelines but this could be addressed “through dilution with bore water”.

A Glimmer of Hope: protected areas

Globally, one-third of protected land is under intense pressure from road building, grazing, urbanization, and other human activities, according to a new study in the 18 May 2018 issue of Science…Nations around the world have committed to preserving biodiversity under the Convention on Biological Diversity (CBD), through protected status designations ranging from nature reserves with strict controls on human impact to regions where people can extract natural resources in a sustainable way. This study suggests that many of these nations are failing to meet their conservation goals.

James Watson, a researcher at the Wildlife Conservation Society and an author of the study, noted that 111 nations currently claim they have meet their obligations under the CBD based on the extent of their protected areas. “But if you only counted the land in protected areas that are not degraded, which play a role in conserving biodiversity, 77 of these nations don’t meet the bar. And it’s a low bar.”

Watson and a team of researchers decided to take advantage of a recently released human footprint map to look at the degradation of protected areas. “The results are quite staggering,” said Watson. “We found that 2.3 million square miles — twice the size of Alaska — was impacted by road building, grazing, logging, roads and urbanization. That is 32.8% of all protected land — the land set aside by nations for the purpose of biodiversity conservation — that] is highly degraded.”  Regions that were found to be particularly burdened by human activity include western Europe and southern Asia.

In terms of protected land that is free of any measurable human pressure, 42% could be classified as such; however, many of these areas are within remote regions of high-latitude nations, such as Russia and Canada.

Some conservation efforts have been fruitful, though. “We did see glimmers of hope,” said Watson…. (e.g., the Keo Seima Wildlife Sanctuary in Cambodia, and Niassa Reserve in Mozambique)

Protected areas designated after 1993 have a lower level of intense human pressure within their borders than those previously designated, the authors found. They suggest this may indicate that more recently designated areas were targeted as protected spaces because they were recognized as being under low human pressure.

The Unquenchable Thirst: water mismanagement

Most of the drinking water consumed in Beijing has travelled 1,432km (895 miles), roughly the distance from New York to Orlando, Florida. Its journey begins in a remote and hilly part of central China at the Danjiangkou reservoir, on the bottom of which lies the drowned city of Junzhou. The water gushes north by canal and pipeline, crosses the Yellow river by burrowing under it, and arrives, 15 days later, in the water-treatment plants of Beijing. Two-thirds of the city’s tap water and a third of its total supply now comes from Danjiangkou.

This winter and spring, the reservoir was the capital’s lifeline. No rain or snow fell in Beijing between October 23rd 2017 and March 17th 2018—by far the longest drought on record. Yet the city suffered no supply disruptions, unlike Shanxi province to the west, where local governments rationed water. The central government is exultant, since the project which irrigates Beijing was built at vast cost and against some opposition.

The South-to-North Water Diversion Project—to give the structure its proper name—is the most expensive infrastructure enterprise in the world. It is the largest transfer of water between river basins in history, and China’s main response to its worst environmental threat, which is (despite all the pollution) lack of water.

The route between Beijing and Danjiangkou, which lies on a tributary of the Yangzi, opened in 2014. An eastern route opened in 2013 using the ancient Grand Canal between Hangzhou and the capital. (Jaw-dropping hydrological achievements are a feature of Chinese history.) A third link is planned on the Tibetan plateau, but since that area is prone to earthquakes and landslides, it has been postponed indefinitely…

Downstream from Danjiangkou, pollution has proved intractable. By diverting water from the Yangzi, the project has made the river more sluggish. It has become less able to wash away contaminants and unable to sustain wetlands, which act as sponges and reduce flooding. To compensate for water taken from their rivers, local governments are also building dams wherever they can to divert it back again. Shaanxi province, for example, is damming the Han river to transfer water to its depleted river Wei….Worst of all, the project diverts not only water but money and attention from China’s real water problem: waste and pollution.

Choked by Hyacinths: Lake Victoria

The report, Freshwater biodiversity in the Lake Victoria Basin (2018), assesses the global extinction risk of 651 freshwater species, including fishes, molluscs, dragonflies, crabs, shrimps and aquatic plants native to East Africa’s Lake Victoria Basin, finding that 20% of these are threatened with extinction. Of the freshwater species assessed, 204 are endemic to the Lake Victoria Basin and three-quarters (76%) of these endemics are at risk of extinction.

The African Lungfish (Protopterus aethiopicus), for example, is declining in the Lake Victoria Basin largely due to overfishing, poor fishing practices and environmental degradation as wetlands are converted to agricultural land. The lungfish is considered a delicacy for some local communities and is an important local medicinal product, used to boost the immune system and treat alcoholism. The lungfish is also traded at market, making it important to the local economy.

Lake Victoria is the world’s second largest freshwater lake by surface area. Its catchment area includes parts of Kenya, Tanzania, Uganda, Burundi and Rwanda. Also referred to as ‘Darwin’s Dreampond’, Lake Victoria is known for its high levels of unique biodiversity. The Lake Victoria Basin harbours immense natural resources including fisheries, forests, wetlands and rangelands….

Pollution from industrial and agricultural sources, over-harvesting of resources and land clearance are among the primary threats to biodiversity in this region. Invasive species also present an important threat to native biodiversity in the basin, affecting 31% of all species and 73% of threatened species. The purple flowered Water Hyacinth (Eichhornia crassipes) was accidentally introduced to Lake Victoria from South America in the 1980s, and at its peak covered close to 10% of the lake surface in dense floating mats. These mats reduce the oxygen and nutrient availability in the water column, which negatively affects native biodiversity. Opportunities for harvesting and exploiting the Water Hyacinth, for example by using the species as fuel in bio-digesters for energy production, are under investigation.

Target Practice on Orangutans

Estimating the number of orangutans is difficult. Researchers have to extrapolate from the number of nests observed. (The apes build new ones to sleep in each night.) A new study published in Current Biology finds that the number of orangutans on Borneo, an island divided between Indonesia and Malaysia, declined by some 148,000 between 1999 and 2015, leaving fewer than 100,000. Within the next 30 years, another 45,000 could disappear. The decline has been steepest, naturally, in areas where the jungle has been razed to plant palm-oil trees. But it is areas that are still forested that account for most of the fall in the orangutan population. This suggests that hunting and crueller activities—carcasses have been found maimed and riddled with airgun pellets—are also taking a bloody toll, says one of the study’s authors, Maria Voigt of the Max Planck Institute, a research organisation in Germany…

Local officials still push for more palm-oil plantations, mines and roads. But tourism in Sumatra’s Gunung-Leuser National Park shows the value of leaving the jungle, and its inhabitants, alone. A night and two days of climbing and crawling in search of orangutans can cost a visitor around $100…Eco-tourism can benefit orangutans, too, if controlled. But tourists often get too close to the animals, risking the transmission of disease, or leave rubbish in the forest…

The Balding Forests of Australia

Most deforestation takes place in poor countries. In richer places, trees tend to multiply. Australia is an unhappy exception. Land clearance is rampant along its eastern coast, as farmers take advantage of lax laws to make room for cattle to feed Asia. WWF, a charity, now ranks Australia alongside Borneo and the Congo Basin as one of the world’s 11 worst “fronts” for deforestation.

The worst damage occurs in the north-eastern state of Queensland, which has more trees left to fell than places to the south, where agriculture is more established… Its bulldozers are at present busier than they have been for a decade. They erased 395,000 hectares of forest, including huge tracts of ancient vegetation, between 2015 and 2016—the equivalent of 1,000 rugby pitches a day. As a share of its forested area, Queensland is mowing down trees twice as fast as Brazil.

Australia has lost almost half its native forest since British colonialists arrived, and much of what remains is degraded. For a time, it seemed that the clear-cutting might come to an end: in the early 2000s several state governments passed bills to reduce deforestation. But in the past decade these have been wound back in every state. Queensland’s land clearance has more than doubled since conservatives loosened its forestry law in 2013, allowing farmers to “thin” trees by up to 75% without a permit. Neighbouring New South Wales recently enacted a similar rule.

Conservationists blame powerful agricultural lobbies. These retort that controls on land clearance push up food prices and cost jobs. Family farmers lament that trees obstruct the big machinery needed to keep their land productive. … In 2014 a landowner in New South Wales murdered an environment officer who was investigating illegal bulldozing. (Authorities in the state are examining at least 300 cases of illegal tree-clearing.)

Yet clearing land eventually hurts farmers too because, without trees, soil erodes and grows saltier. Deforestation releases carbon dioxide into the atmosphere, spurring global warming, and reduces regional rainfall…. Loss of habitat has brought many species, including the koala, to the brink of extinction.

Deforestation Tolerance: Amazon

Amazon generates approximately half of its own rainfall by recycling moisture 5 to 6 times as airmasses move from the Atlantic across the basin to the west.  From the start, the demonstration of the hydrological cycle of the Amazon raised the question of how much deforestation would be required to cause this hydrolological cycle to degrade to the point of being unable to support rain forest ecosystems.

High levels of evaporation and transpiration that forests produce throughout the year contribute to a wetter atmospheric boundary layer than would be the case with non-forest.This surface-atmosphere coupling is more important where large-scale factors for rainfall formation are weaker, such as in central and eastern Amazonia. Near the Andes, the impact of at least modest deforestation is less dramatic because the general ascending motion of airmasses in this area induces high levels of rainfall in addition to that expected from local evaporation and transpiration.

Where might the tipping point be for deforestation-generated degradation of the hydrological cycle? The very first model to examine this question  showed that at about 40% deforestation, central, southern and eastern Amazonia would experience diminished rainfall and a lengthier dry season, predicting a shift to savanna vegetation to the east.

Moisture from the Amazon is important to rainfall and human wellbeing because it contributes to winter rainfall for parts of the La Plata basin, especially southern Paraguay, southern Brazil, Uruguay and central-eastern Argentina; in other regions, the moisture passes over the area, but does not precipitate out. Although the amount contributing to rainfall in southeastern Brazil is smaller than in other areas, even small amounts can be a welcome addition to urban reservoirs…

In recent decades, new forcing factors have impinged on the hydrological cycle: climate change and widespread use of fire to eliminate felled trees and clear weedy vegetation. Many studies show that in the absence of other contributing factors, 4° Celsius of global warming would be the tipping point to degraded savannas in most of the central, southern, and eastern Amazon. Widespread use of fire leads to drying of surrounding forest and greater vulnerability to fire in the subsequent year.

We believe that negative synergies between deforestation, climate change, and widespread use of fire indicate a tipping point for the Amazon system to flip to non-forest ecosystems in eastern, southern and central Amazonia at 20-25% deforestation.

We believe that the sensible course is not only to strictly curb further deforestation, but also to build back a margin of safety against the Amazon tipping point, by reducing the deforested area to less than 20%, for the commonsense reason that there is no point in discovering the precise tipping point by tipping it. At the 2015 Paris Conference of the Parties, Brazil committed to 12 million ha of reforestation by 2030. Much or most of this reforestation should be in southern and eastern Amazonia.

An Earth Bank of Codes: who owns what in the biological world

A project with the scale and sweep of the original Human Genome Project…should be to gather DNA sequences from specimens of all complex life on Earth. They decided to call it the Earth BioGenome Project (EBP).

At around the same time as this meeting, a Peruvian entrepreneur living in São Paulo, Brazil, was formulating an audacious plan of his own. Juan Carlos Castilla Rubio wanted to shift the economy of the Amazon basin away from industries such as mining, logging and ranching, and towards one based on exploiting the region’s living organisms and the biological information they embody. At least twice in the past—with the businesses of rubber-tree plantations, and of blood-pressure drugs called ACE inhibitors, which are derived from snake venom—Amazonian organisms have helped create industries worth billions of dollars. ….

For the shift he had in mind to happen, though, he reasoned that both those who live in the Amazon basin and those who govern it would have to share in the profits of this putative new economy. And one part of ensuring this happened would be to devise a way to stop a repetition of what occurred with rubber and ACE inhibitors—namely, their appropriation by foreign firms, without royalties or tax revenues accruing to the locals.

Such thinking is not unique to Mr Castilla. An international agreement called the Nagoya protocol already gives legal rights to the country of origin of exploited biological material. What is unique, or at least unusual, about Mr Castilla’s approach, though, is that he also understands how regulations intended to enforce such rights can get in the way of the research needed to turn knowledge into profit. To that end he has been putting his mind to the question of how to create an open library of the Amazon’s biological data (particularly DNA sequences) in a way that can also track who does what with those data, and automatically distribute part of any commercial value that results from such activities to the country of origin. He calls his idea the Amazon Bank of Codes.

Now, under the auspices of the World Economic Forum’s annual meeting at Davos, a Swiss ski resort, these two ideas have come together. On January 23, 2018 it was announced that the EBP will help collect the data to be stored in the code bank. The EBP’s stated goal is to sequence, within a decade, the genomes of all 1.5m known species of eukaryotes. ..That is an ambitious timetable. The first part would require deciphering more than eight genomes a day; the second almost 140; the third, about 1,000. For comparison, the number of eukaryotic genomes sequenced so far is about 2,500…

Big sequencing centres like BGI in China, the Rockefeller University’s Genomic Resource Centre in America, and the Sanger Institute in Britain, as well as a host of smaller operations, are all eager for their share of this pot. For the later, cruder, stages of the project Complete Genomics, a Californian startup bought by BGI, thinks it can bring the cost of a rough-and-ready sequence down to $100. A hand-held sequencer made by Oxford Nanopore, a British company, may be able to match that and also make the technology portable…..It is an effort in danger of running into the Nagoya protocol. Permission will have to be sought from every government whose territory is sampled. That will be a bureaucratic nightmare. Indeed, John Kress of the Smithsonian, another of the EBP’s founders, says many previous sequencing ventures have foundered on the rock of such permission. And that is why those running the EBP are so keen to recruit Mr Castilla and his code bank.

The idea of the code bank is to build a database of biological information using a blockchain. Though blockchains are best known as the technology that underpins bitcoin and other crypto-currencies, they have other uses. In particular, they can be employed to create “smart contracts” that monitor and execute themselves. To obtain access to Mr Castilla’s code bank would mean entering into such a contract, which would track how the knowledge thus tapped was subsequently used. If such use was commercial, a payment would be transferred automatically to the designated owners of the downloaded data. Mr Castilla hopes for a proof-of-principle demonstration of his platform to be ready within a few months.

In theory, smart contracts of this sort would give governments wary of biopiracy peace of mind, while also encouraging people to experiment with the data. And genomic data are, in Mr Castilla’s vision, just the start. He sees the Amazon Bank of Codes eventually encompassing all manner of biological compounds—snake venoms of the sort used to create ACE inhibitors, for example—or even behavioural characteristics like the congestion-free movement of army-ant colonies, which has inspired algorithms for co-ordinating fleets of self-driving cars. His eventual goal is to venture beyond the Amazon itself, and combine his planned repository with similar ones in other parts of the world, creating an Earth Bank of Codes.

[I]f the EBP succeeds, be able to use the evolutionary connections between genomes to devise a definitive version of the tree of eukaryotic life. That would offer biologists what the periodic table offers chemists, namely a clear framework within which to operate. Mr Castilla, for his part, would have rewritten the rules of international trade by bringing the raw material of biotechnology into an orderly pattern of ownership. If, as many suspect, biology proves to be to future industries what physics and chemistry have been to industries past, that would be a feat of lasting value.

Islands of Paradise, Sewage and Garbage

Cesspools—holes in the ground where untreated human waste is deposited—have become a crisis in Hawaii, threatening the state’s drinking water, its coral reefs and the famous beaches that are the lifeblood of its tourist economy.  Sewage from cesspools is seeping into some of Hawaii’s ocean waters, where it has been blamed for infections suffered by surfers and snorkelers. It is also entering the drinking water in part of the state, pushing nitrate levels close to the legal limit.

Hawaii has 88,000 cesspools across its eight major islands, more than any other state. Collectively, they deposit 53 million gallons of raw sewage into the ground every day, according to the state health department. More than 90% of the state’s drinking water comes from groundwater wells…

Replacing all of the state’s cesspools with alternate sewage systems would cost at least $1.75 billion, according to the health department…At one groundwater well, nitrate levels are already at 8.7 milligrams a liter; the legal limit is 10, and the Department of Health estimated that some parts of the aquifer are already over that limit. Environmentalists say they are worried about the potential effect of the water on infants, who can be killed by high levels on nitrates, which are chemicals found in fertilizer and sewage.

Many bathrooms in homes outside Honolulu still pump sewage into nearby holes in the ground.  Yet, some residents resist plans to replace cesspools, worried about expense. In January 2018, Upcountry Maui residents overwhelmed a Department of Public Health meeting, complaining about potential costs.

Excerpt from Hawaii’s Big Headache: Cesspools, Wall Street Journal, Feb. 12, 2018

The Maritime Environment Protection Authority’s (MEPA) of Sri Lanka spent millions of rupees on coastal cleanups last year — a reflection of “spending public money for public waste,” as the MEPA’s General Manager and CEO, Dr. Terney Pradeep Kumara, puts it.

A large proportion of the problem is attributable to inland waste, he notes. “It is not merely what is dumped directly on the beaches, but all that flows through canals and rivers,” he says, pointing out that other triggers, including the fisheries and the tourism sector, are only secondary to inland waste which ends up on the coast. Added to the burden is the garbage which flows from India, Indonesia and Thailand, he says. The MEPA’s role in controlling pollution covers Sri Lanka’s 1640 km coastal belt and extends up to 200 nautical miles to the deep sea, the area, which, according to Dr. Pradeep Kumara, is eight times the size of Sri Lanka’s land area.

The garbage dumped in the coastal vegetation is contributing to the dengue problem…especially the fishing craft, both in use and abandoned, in which water is stagnated.”   Mitigating inland pollution is seen by MEPA authorities as the first step in realising cleaner beaches. They moot a site-specific garbage disposal system, as opposed to a ‘blanket system’. “What works for Colombo will not work for other areas,” says Dr. Pradeep Kumara.

Turning Oceans into Muck

Oxygen is critical to the health of the planet. It affects the cycles of carbon, nitrogen and other key elements, and is a fundamental requirement for marine life from the seashore to the greatest depths of the ocean. Nevertheless, deoxygenation is worsening in the coastal and open ocean. This is mainly the result of human activities that are increasing global temperatures (CO2-induced warming) and increasing loads of nutrients from agriculture, sewage, and industrial waste, including pollution from power generation from fossil fuels and biomass.

Facts: During the past 50 years the area of low oxygen water in the open ocean has increased by 4.5 million km2. The world’ oceans are now losing approximately  1 gigaton of oxygen each year. The Millennium Ecosystem Assessment released by the UN in 2005 reported that nitrogen containing compounds (e.g. sewage, fertilizers) release into the oceans grew 80 percent from 1860 to 1990.  Increasing temperatures will reduce the capacity of the ocean to hold oxygen in the future. Oxygen deficiency is predicted to worsen in estuaries, coastal areas and oxygen minimum zones in the open ocean. The ocean’s capacity to produce oxygen will be reduced in the future.
Habitat loss is expected to worsen, leading to vertical and horizontal migration of species.

Oxygen deficiency will alter biogeochemical cycles and food webs. Lower oxygen concentrations are projected to result in a decrease in reproductive capacity and biodiversity loss. There are important local decreases of commercially important species and aquaculture production. Harmful Algal Blooms will be exacerbated from nutrients released in bottom waters due to hypoxia (e.g. in the Baltic Sea).Reduced ocean oxygen concentrations will lead to an increase in greenhouse gas emissions, thereby initiating feedbacks on climate change.

Old Continents, New Trees

In the 1920s, when Ireland became independent, it was thought to have just 220,000 acres (90,000 hectares) of woods, covering about 1% of the land. Once-extensive forests had been shrinking for centuries…In 2017, though, almost 11% of Ireland is covered with forest, and an unknown additional amount by small woods and scattered trees. The government’s target is to cover 18% of the land area with forests by 2046. Ireland is behind schedule. Still, about 6,000 hectares of new forest ought to be planted this year, while almost none will be lost. It is part of a broad trend: the foresting of the West.

Trees are spreading in almost every European country. Because many of these forests are young, the quantity of wood in them is growing faster than their extent. Europe’s planted forests put on a little more than 1.1m cubic metres of wood per day. For comparison, the iron in the Eiffel Tower is about 930 cubic metres. Russia’s forests spread more slowly in percentage terms between 2005 and 2015, but, because Russia is so big, more than in the entire European Union in absolute terms. Forests now occupy a third of America’s land, having grown by 2% in the past decade. They are even expanding in Australia, following a long decline.

Deforestation in South America and Africa rightly gets most of conservationists’ attention. That loss is huge—equivalent to about 4.8m hectares a year, which far outweighs gains elsewhere. Yet the foresting of rich countries is still one of the world’s great land-use changes. It seems just as unstoppable as the deforestation of poorer places. It has plenty of critics, too.

The growth of forests is partly a result of changes to food markets. As the best farming areas have become more productive, and as rich countries have imported more of their food, marginal land has become unusable for ordinary agriculture…Forests are also growing because governments have favored them through laws and subsidies….Since the 1990s environmental considerations have weighed more heavily. Forests are increasingly valued as sponges for heavy rain, as wildlife habitats and as carbon sinks…

Planted forests are far from universally popular, though. Between June and October 2017, forest fires in Spain and Portugal killed more than 100 people and darkened Europe’s skies. The fires were partly blamed on the spread of non-native trees, especially eucalyptus. That Australian import, which was planted with support from the World Bank, among others, grows so quickly that trees can be harvested for pulp when less than ten years old. It also burns readily, scattering embers far afield. Portugal’s government has begun to restrict planting, in an effort to prevent the country from turning into what one green group calls “Eucalyptugal”.

The eucalyptus tree is a scapegoat for a bigger problem, argues Marc Castellnou, a fire analyst in Spain. The real trouble is that forests in Portugal and Spain have expanded quickly, with little thought for the consequences. Well-managed eucalyptus plantations are not the biggest danger—much worse are ill-managed ones with lots of underbrush and fallen wood, and the impromptu forests that grow on abandoned farms. The fires that get going in such forests jump to the treetops and burn so energetically that they cannot be stopped.

In Ireland, the criticisms are different. The country’s default tree is the sitka spruce, a fast-growing, damp-tolerant conifer from America’s Pacific Northwest. Spruce plantations are said to be devoid of life—vertical deserts of dark green. They are accused of wrecking rural communities and driving farmers off the land….

The first charge is false. Mark Wilson of the British Trust for Ornithology says that conifer plantations support more bird life per hectare than farmland, largely because they harbour more insects. Inevitably, some birds benefit more than others. The march of conifers across Britain and Ireland has increased the numbers of pine-loving birds such as siskins and crossbills. Conifers are also loved by crows—which is less obviously good, because crows raid the nests of rare birds such as curlews.

The second accusation, that trees push out other kinds of agriculture, is only partly true. Forestry subsidies and regulations have indeed distorted Ireland’s land market.

Red-Dead: water crisis in the Middle East

The Dead Sea is dying. Half a century ago its hyper-salty, super-pungent waters stretched 80km from north to south. That has shrunk to just 48km at its longest point. The water level is falling by more than a meter per year. All but a trickle from its source, the Jordan River, is now used up before it reaches the sea. “It will never disappear, because it has underground supplies, but it will be like a small pond in a very big hole,” says Munqeth Mehyar of EcoPeace, an NGO.

Until the summer of 2017 Israel and Jordan, which share the sea, were trying to slow the decline. The “Red-Dead project”, as it is called, would desalinate seawater at the Jordanian port of Aqaba and pump 200m cubic metres of leftover brine into the Dead Sea each year. That would not be enough to stabilise the sea, which needs at least 800m cubic metres to stay at current levels. Still, it would help—and the project has a much more important benefit.

The World Bank defines water scarcity as less than 1,000 cubic metres per person annually. Jordan can provide less than 15% of that. The Aqaba plant would send fresh water to southern towns in both Jordan and Israel. In return for its share, Israel agreed to pump an equal amount to parched northern Jordan, where most of the population lives.

But the project was now on hold due a dispute between Jordan and Israel. On July 23rd, 2017 a Jordanian teenager delivering furniture to the Israeli embassy stabbed a security guard. The guard opened fire, killing both his assailant and an innocent bystander….

Jordan is already one of the world’s most arid countries. Climate change will make matters worse. By the end of the century, say scientists from Stanford University, Jordan could be 4°C hotter, with about a third less rain. It needs to rationalise water consumption. And Israel, which wants a stable neighbour to its east, has an interest in getting water projects back on track.

The Silent Environmentalists

Elephant ears are leafy vegetables. African locusts are tree-borne legumes. All are standard fare in various parts of Africa. What they also have in common is that they are, from the point of view of plant breeders, orphans. They are neglected by breeders because they are not cash crops. Conversely, they are not cash crops because they are neglected by breeders.

That neglect matters. The cereals which dominate human diets—rice, wheat and maize—have had their yields and nutritional values boosted over the years by scientific breeding programmes. In the modern era of genomics, they have had their DNA scrutinised down to the level of individual base pairs, the molecular letters in which genetic information is written. They are as far removed, nutritionally, from their ancestors of as little as two centuries ago as those ancestors were from the wild plants which begat them. Orphan crops have yet to undergo such a genetic revolution.

Even for adults, a lack of calories and essential nutrients is harmful. For children it can be devastating. Poor childhood nutrition leads to stunting—inadequate bodily development, including the development of the brain. A report published by the World Health Organisation on November 16th, 2017 suggests that almost a third of Africa’s children, nearly 60m of them, are stunted. And stunted children grow into adults unable to achieve their potential. Researchers at the World Bank reckon the effects of stunting have reduced Africa’s GDP by 9-10% from what it would otherwise be.

One way to reduce stunting would be to improve the crops that Africans, particularly those in the countryside, actually eat—in other words, orphan crops. Such improvement is the purpose of two recent, interrelated projects that are now getting into their strides. Both are based in Nairobi and are conducted under the auspices of the World Agroforestry Centre, an international non-governmental research organisation. One is the African Orphan Crops Consortium (AOCC). The other is the African Plant Breeding Academy. The AOCC’s task is to obtain complete sequences of the DNA of 101 neglected food crops

Breeding and disseminating new crops is a long-winded business, but a DNA-based approach has already shown promise. One scientist who is embracing it is Robert Mwanga of the International Potato Centre. Dr Mwanga was an early proponent of the scientific improvement of African crops. His own work, for which he was awarded the World Food prize in 2016, is on sweet potatoes. The varieties of these root-tubers that were popular in Uganda, his native land, and other parts of Africa in the mid-1980s, when he began his studies, are deficient in vitamin A. A lack of this vitamin damages children’s eyesight and opens them to infection by such things as measles. This is a disease that can kill, and, if it does not, it can cause brain damage.  Starting with Asian varieties that had more vitamin A in them, Dr Mwanga bred a dozen strains that are vitamin-A rich and have more dry matter (and thus more calorific value) than African landraces. He then led a campaign to encourage local farmers to adopt his novelties—which they did…

Julia Sibiya of the University of KwaZulu Natal, in Durban, meanwhile, is working on sorghum, another under-studied African crop. She is also working with Dr Achigan-Dako to set up MoBreed, a pan-African collaboration with the self-appointed task of improving ten orphan crops, including Kersting’s groundnut, the African custard apple and fonio, a type of millet.

Happiness Oselebe… is even more ambitious. Dr Oselebe works at Ebonyi State University in Nigeria. Not content with improving existing crops, she wants to create a new one by domesticating serendipity berries. These are wild vines that produce a protein 3,000 times as sweet as table sugar. That, she thinks, could be the starting-point not merely for something grown for local consumption, but of an industrial-scale cash crop.

Cut or Pay up: Net Negative Carbon Emissions

Sweden’s parliament passed a law in June which obliges the country to have “no net emissions” of greenhouse gases into the atmosphere by 2045. The clue is in the wording. This does not mean that three decades from now Swedes must emit no planet-heating substances; even if all their electricity came from renewables and they only drove Teslas, they would presumably still want to fly in aeroplanes, or use cement and fertiliser, the making of which releases plenty of carbon dioxide. Indeed, the law only requires gross emissions to drop by 85% compared with 1990 levels. But it demands that remaining carbon sources are offset with new carbon sinks. In other words greenhouse gases will need to be extracted from the air

[I]f the global temperature is to have a good chance of not rising more than 2ºC above its pre-industrial level, as stipulated in the Paris climate agreement of 2015, worldwide emissions must similarly hit “net zero” no later than 2090. After that, emissions must go “net negative”, with more carbon removed from the stock than is emitted…

To keep the temperature below a certain level means keeping within a certain “carbon budget”—allowing only so much to accumulate, and no more. Once you have spent that budget, you have to balance all new emissions with removals. If you overspend it…you have a brief opportunity to put things right by taking out more than you are putting in…

Climate scientists like Mr Henderson have been discussing negative-emissions technologies (NETs) with economists and policy wonks since the 1990s. [But] NETs were conspicuous by their absence from the agenda of the annual UN climate jamboree which ended in Bonn on November 17th 2017.

 Reforesting logged areas or “afforesting” previously treeless ones presents no great technical challenges. More controversially, they also tend to invoke “bioenergy with carbon capture and storage” (BECCS). In BECCS, power stations fuelled by crops that can be burned to make energy have their carbon-dioxide emissions injected into deep geological strata, rather than released into the atmosphere….

The Carbon Capture and Storage (CCS)  technologies that exist today, under development by companies such as Global Thermostat in America, Carbon Engineering in Canada or Climeworks of Switzerland, remain pricey. In 2011 a review by the American Physical Society to which Ms Wilcox contributed put extraction costs above $600 per tonne, compared with an average estimate of $60-250 for BECCS…

Much of the gas captured by Climeworks and other pure NETs firms (as opposed to fossil-fuel CCS) is sold to makers of fizzy drinks or greenhouses to help plants grow. It is hard to imagine that market growing far beyond today’s total of 10m tonnes. And in neither case is the gas stored indefinitely. It is either burped out by consumers of carbonated drinks or otherwise exuded by eaters of greenhouse-grown produce…..

One way to create a market for NETs would be for governments to put a price on carbon. Where they have done so, the technologies have been adopted. Take Norway, which in 1991 told oil firms drilling in the North Sea to capture carbon dioxide from their operations or pay up. This cost is now around $50 per tonne emitted; in one field, called Sleipner, the firms have found ways to pump it back underground for less than that. A broader carbon price—either a tax or tradable emissions permits—would promote negative emissions elsewhere, too…

Another concern is the impact on politicians and the dangers of moral hazard. NETs allow politicians to go easy on emission cuts now in the hope that a quick fix will appear in the future.

The Luxury of Swimmable Waters

Data published in 2013 suggested that it was not safe for people to submerge themselves in 60% of New Zealand’s waterways. “We used to swim in these rivers,” says Sam Mahon, the artist. “Now they’ve turned to crap… [T]he real villains behind New Zealand’s deteriorating water quality are still at large…intensive dairy farms…

The first concern is bovine urine, which is rich in nitrogen. Nitrogen can cause toxic algae to grow when it leaches into water. Nitrogen fertiliser, used to increase fodder yields so that more cows can be raised on less land, exacerbates the problem….

At many of the sites where the government tests the groundwater it contains too much nitrate to be safe to drink—a particular problem in New Zealand, since water in much of the country has long been considered clean enough that it is used as drinking water with only minimal treatment. In Canterbury, one of the most polluted areas, expectant mothers are told to test tap water to avoid “blue baby syndrome”, a potentially fatal ailment thought to be caused by nitrates. The poisonous blooms have killed dogs.

An even greater concern for human health comes from cow dung, which contains nasty bacteria such as E.coli….And then there is the damage to native flora and fauna. The algal blooms suck the oxygen from rivers. Sediment washed from farmland can also choke the life out of streams. Almost three-quarters of native species of freshwater fish are under threat.

…One recent tally suggested that just 2,000 of the thirstiest dairies suck up as much water as 60m people would—equivalent to the population of London, New York, Tokyo, Los Angeles and Rio de Janeiro combined. …

Dairies are trying to clean up their act. Farmers have fenced off thousands of kilometres of rivers to prevent livestock from wading in. Some have planted trees along waterways to curb erosion; others remove animals from muddy fields during winter. Some parts of the country are using more sophisticated techniques: around Lake Taupo, the country’s biggest lake, farmers can buy and sell nitrogen allowances in a cap-and-trade scheme. A technique called “precision irrigation” may curb both water consumption and the leaching of nitrogen.

Earlier this year the National Party launched a plan to make 90% of rivers “swimmable” by 2040. Yet it ignored several recommendations of a forum of scientists and agrarians established to thrash out water policy….Environmentalists argue that the national dairy herd should be cut to prevent further damage…And pollutants moving through groundwater can take decades to emerge in lakes. The worst may still be to come.

Cocoa Production and Forest Loss

At the UN Climate Change Conference (COP23) in Bonn in November 2017 top cocoa-producing countries Côte d’Ivoire and Ghana with leading chocolate and cocoa companies have announced far-reaching Frameworks for Action to end deforestation and restore forest areas.  Central to the Frameworks is a commitment to no further conversion of any forest land for cocoa production.  The companies and governments pledged to eliminate illegal cocoa production in national parks, in line with stronger enforcement of national forest policies and development of alternative livelihoods for affected farmers. Côte d’Ivoire and Ghana combined produce nearly two-thirds of the world’s annual supply of cocoa, the main ingredient in chocolate and a range of other consumer products…

Up-to-date maps on forest cover and land-use, as well as socio-economic data on cocoa farmers and their communities will be developed and publicly shared by the governments. Chocolate and cocoa industry agree to put in place verifiable monitoring systems for traceability from farm to the first purchase point for their own purchases of cocoa, and will work with the governments of Côte d’Ivoire and Ghana to ensure an effective national framework for traceability for all traders in the supply chain.

The two governments and companies agree through the Frameworks to accelerate investment in long-term sustainable production of cocoa, with an emphasis on “growing more cocoa on less land,”. Key actions include provision of improved planting materials, training in good agricultural practices, and development and capacity-building of farmers’ organizations.  Sustainable livelihoods and income diversification for cocoa farmers will be accelerated through food crop diversification, agricultural inter-cropping, development of mixed agro-forestry systems, and other income generating activities designed to boost and diversify household income while protecting forests.

The governments and companies, which represent and estimated 80+ percent of global cocoa usage, commit to full and effective consultation and participation of cocoa farmers in the process…The governments and companies have committed to a comprehensive monitoring process, including a satellite-based monitoring system to track progress on the overall deforestation target, and annual publicly disclosed reporting on progress and outcomes related to the specific actions in each Framework.

Excerpts from Cocoa and Forests Initiative

Companies that have joined the initiative include; Cargill, General Mills, Godiva, Hershey, Mars, Mondelēz, and Nestlé.

Exporting Apes Alive

Daniel Stiles, a self-styled ape trafficking detective in Kenya, had been scouring Instagram, Facebook and WhatsApp for weeks, looking for pictures of gorillas, chimps or orangutans. He was hoping to chip away at an illicit global trade that has captured or killed tens of thousands of apes and pushed some endangered species to the brink of extinction.

Malnourished and terrified apes have been seized across the world, in undercover busts or at border checkpoints, in countries as varied as France, Nepal, Thailand, the Democratic Republic of Congo and Kuwait. Two years ago, at Cairo’s international airport, the Egyptian authorities discovered a baby chimp curled up into a ball and stashed in a piece of hand luggage. Just this summer, the authorities in Cameroon stopped a smuggler at a roadblock who was trying to move 100 pounds of pangolin scales and a tiny chimp, not even a month old, hidden in a plastic sack…

Wildlife researchers say that a secret ape pipeline runs from the lush forests of central Africa and Southeast Asia, through loosely policed ports in the developing world, terminating in wealthy homes and unscrupulous zoos thousands of miles away. The pipeline, documents show, is lubricated by corrupt officials (several have been arrested for falsifying export permits) and run by transnational criminal gangs that have recently drawn the attention of Interpol, the international law enforcement network.

Apes are big business — a gorilla baby can cost as much as $250,000 — but who exactly is buying these animals is often as opaque as the traffickers’ identity.

Wildlife officials said that a handful of Western businessmen had also been arrested. But the majority of recent busts, they added, have been in Africa or Southeast Asia, usually of low-level traffickers or poorly paid underlings, not the bosses who control underground exports and travel abroad to make deals…

“They have consciousness, empathy and understanding,” said Jef Dupain, an ape specialist for the African Wildlife Foundation. “One day we will wonder how did we ever come up with the idea to keep them in cages.”…

But a baby was different, he said. There was a specific market for infant apes, so he would sell them alive, for at least $10 each, to local traders who would then smuggle them to Kinshasa and sell them to foreigners for many times that amount…

In Boende, a small town up another tributary of the Congo River, three hunters were recently caught with bonobo carcasses and sentenced to several years in a stifling colonial-era prison. The men said they were simply trying to feed their families by selling bonobo meat. But poaching an ape is a serious crime in Congo, and nonprofit wildlife groups have been assisting the Congolese authorities in prosecuting offenders.“There is a culture here to eat meat, meat from the forest,” said the town’s prosecutor, Willy Ndjoko Kesidi. “Me, I like fish.”  Mr. Kesidi expressed some sympathy for the hunters he had just jailed, saying that the prison where they were housed was a horrible place where many prisoners had died…

Many illegal wildlife transactions start online, specifically through Instagram or WhatsApp. Mr. Stiles has made several trips to the United Arab Emirates, which he considers a new hub for the illegal online wildlife business. Dealers in the Middle East have posted many pictures of apes for sale, sometimes advertising them as friendly pets for children…

Several years ago, the Indonesian police rescued a female orangutan who had been shaved and was being used as a prostitute at a brothel.

Saving Iconic Rivers: Ganges

The Ganges, arguably the lifeline of India, has its origin in the Himalayas. Once it crosses Gangotri, it flows through Haridwar collecting industrial, agricultural and human waste on its way. Before it culminates in the Bay of Bengal, it passes through various towns and villages lacking sanitation. The Government of India is rolling up its sleeves to clean the 2525 KM long-Ganga and facilitate its flow as it is the source of water for more than 40 per cent of India’s population.

The Institution of Engineering and Technology (IET) is non-profit engineering organisation founded 145 years ago, the IET is one of the world’s leading professional societies for the engineering and technology community. The IET has more than 167,000 members across 150 countries. In India, the IET has over 13,000 members, eight Local Networks and focuses on Energy, Transport, Information & Communications, IoT and Education sectors.

In March 2017, a panel formed by the Institution of Engineering and Technology (IET) on IoT (Internet of Things) were invited to consult the Government of India’s National Mission for Clean Ganga (NMCG) to discuss the ways to clean the river. According to IET, the leaders discussed and tried to identify ways to improve the water flow in Ganga, better treatment of pollutants via sewage and effluent treatment plants, need for controlling unregulated sewage, open defecation,  and handling chemical runoff from agricultural lands (fertilisers and pesticides).

The IoT technology could be used in providing real-time information of pollution status and enabling the industries and societies to find alternate means of disposal of waste.   Other technologies being used to clean up the river Unmanned robotic water surface vehicle with drones: The vehicle can be programmed to collect all the pollutant waste through its arms and offload the same. It works 24X7 and under all weather conditions. More, it can actually submerge to clean up pollutants on even the riverbed. A set of drones is used with it to collect videos of the pollutants.

Gumps- Detectors for pipeline leaks: The Guided Ultrasonic Monitoring of Pipe Systems (GUMPS) can detect oil leakages from oil pipelines that are laid across the river bed of the Ganga River. They continuously monitor pipelines and alert any impending leaks, thus preventing loss of marine life and pollution due to oil leakages.

Don’t Cut that Tree!

A revolutionary new approach to measuring changes in forest carbon density has helped scientists determine that the tropics now emit more carbon than they capture, countering their role as a net carbon “sink.”*

“These findings provide the world with a wakeup call on forests,” said scientist Alessandro Baccini, the report’s lead author….Forests are the only carbon capture and storage ‘technology’ we have in our grasp that is safe, proven, inexpensive, immediately available at scale, and capable of providing beneficial ripple effects—from regulating rainfall patterns to providing livelihoods to indigenous communities.”

Using 12 years (2003-2014) of satellite imagery, laser remote sensing technology and field measurements, Baccini and his team were able to capture losses in forest carbon from wholesale deforestation as well as from more difficult-to-measure fine-scale degradation and disturbance …from smallholder farmers removing individual trees for fuel wood. These losses can be relatively small in any one place, but added up across large areas they become considerable.

[T] he researchers discovered that tropics represent a net source of carbon to the atmosphere — about 425 teragrams of carbon annually – which is more than the annual emissions from all cars and trucks in the United States.

Unjustifiable Extinctions

The world’s botanic gardens contain at least 30% of all known plant species, including 41% of all those classed as ‘threatened’, according to the most comprehensive analysis to date of diversity in ‘ex situ’ collections: those plants conserved outside natural habitats.

The study, in September 2017 in the journal Nature Plants, found that the global network of botanic gardens conserves living plants representing almost two-thirds of plant genera and over 90% of plant families.  However, researchers from the University of Cambridge discovered a significant imbalance between temperate and tropical regions. The vast majority of all plants species grown ex situ are held in the northern hemisphere. Consequently, some 60% of temperate plant species were represented in botanic gardens but only 25% of tropical species, despite the fact that the majority of plant species are tropical.

For the study, researchers analysed datasets compiled by the Botanic Gardens Conservation International (BGCI)….

“The global network of botanic gardens is our best hope for saving some of the world’s most endangered plants,” said senior author Dr Samuel Brockington, a researcher at Cambridge’s Department of Plant Sciences as well as a curator at the University’s own Botanic Garden….“Currently, an estimated one fifth of plant diversity is under threat, yet there is no technical reason why any plant species should become extinct.   “If we do not conserve our plant diversity, humanity will struggle to solve the global challenges of food and fuel security, environmental degradation, and climate change.”

The plants not currently grown in botanic gardens are often more interesting than those that are, say the researchers. Hydrostachys polymorpha, for example, an African aquatic plant that only grows in fast flowing streams and waterfalls, or the tiny parasitic plant Pilostyles thurberi – only a few millimetres long, it lives completely within the stem tissue of desert shrubs.  Species from the most ancient plant lineages, termed ‘non-vascular’ plants, are currently almost undocumented in botanic gardens – with as few as 5% of all species stored in the global network. These include plants such as the liverworts and mosses.

“Non-vascular species are the living representatives of the first plants to colonise the land,” said Brockington. “Within these plants are captured key moments in the early evolutionary history of life on Earth, and they are essential for understanding the evolution of plants”

Salt Lakes of the World

 

Utah Great Salt Lake has shrunk to a depth of about 14 feet—nearly half its former average since it was settled by the Mormons 170 years ago. Under a controversial engineering plan, the lake would recede even further….State engineers want to siphon off some of the river water that flows into the lake and use it for the Salt Lake City area’s booming population. Proponents say the plan, which calls for lapping up a fifth of Bear River’s current unused flow, is essential for meeting the region’s needs.

But critics note that the diversion would cause the lake to drop by almost a foot, according to state estimates, eventually exposing 30 square miles of lake bed and potentially worsening the dust storms that regularly blanket the region and ruining a fragile wetlands habitat.

The debate echoes concerns heard in many other arid parts of the world. Salt lake ecology is especially delicate and requires a certain amount of fresh water to maintain a saline balance. Brine shrimp, for instance, could die off if the water becomes too salty.

In the Middle East, diversion of the Jordan and other rivers that feed the Dead Sea has shriveled the famous body of saltwater and its once robust tourism. The Aral Sea between Kazakhstan and Uzbekistan has shrunk to about 10% of its original size after diversions.

Critics, including environmental groups and affected businesses, say that under the new diversion plan lake-dependent businesses such as brine shrimp fishing would suffer, as would farmers whose land could be inundated upstream if existing dams are raised to retain more water. In all, the lake accounts for an estimated $1.3 billion in annual economic output, according to Utah State University, much of it from the shrimping industry, as well as mineral extraction and tourism.

The plan would also destroy wetlands along the lake shoreline that provide food and habitat for an estimated eight million birds, said Zach Frankel, executive director of Utah Rivers Council, an environmental group opposed to the project.

But proponents say the diversion of up to 72 billion gallons of water—enough to meet the needs of a city of one million for a year—is needed to forestall anticipated shortages for one of the fastest-growing regions in the country….“If Utah continues to grow, it’s not a matter of if but when we are going to need more water,” said state Sen. Stuart Adams, the Republican majority whip, who sponsored a bill to begin funding the estimated $1.5 billion project.

Policing the Amazon Jungle

The small town of Apui sits at the new frontline of Brazil’s fight against advancing deforestation…  The home of 21,000 people in southern Amazonas state was long protected by its remote location from illegal loggers, ranchers and farmers who clear the forest.  Now those who would destroy the jungle are moving in from bordering states, following the Transamazon Highway, which is little more than a red-dirt track in this part of the rainforest.

First come the loggers, who illegally extract valued lumber sold in far-off cities. The cattle ranchers follow, burning the forest to clear land and plant green pasture that rapidly grows in the tropical heat and rain. After the pasture is worn out, soy farmers arrive, planting grain on immense tracts of land…

Roughly 7,989 square kilometres (3,085 square miles) of forest were destroyed in 2016, a 29 percent increase from the previous year and up from a low of 4,571 square kilometers in 2012, according to the PRODES satellite monitoring system.

Then there are the fires.  Apui ranked first in the country for forest fires in the first week of August 2017, according to the ministry.

At their best the environmental agents can slow but not stop the destruction. They raid illegal logging camps, levy large fines that are rarely collected and confiscate chainsaws to temporarily impede the cutting.  Costa acknowledges that the roughly 1,300 environmental field agents who police a jungle area the size of western Europe have a difficult task, at the very least.

Unsafe Genes: DARPA

DARPA created the Safe Genes program to gain a fundamental understanding of how gene editing technologies function; devise means to safely, responsibly, and predictably harness them for beneficial ends; and address potential health and security concerns related to their accidental or intentional misuse. Today, DARPA announced awards to seven teams that will pursue that mission, led by: The Broad Institute of MIT and Harvard; Harvard Medical School; Massachusetts General Hospital; Massachusetts Institute of Technology; North Carolina State University; University of California, Berkeley; and University of California, Riverside. DARPA plans to invest $65 million in Safe Genes over the next four years as these teams work to collect empirical data and develop a suite of versatile tools that can be applied independently or in combination to support bio-innovation and combat bio-threats.

Gene editing technologies …[can] selectively disable cancerous cells in the body, control populations of disease-spreading mosquitos, and defend native flora and fauna against invasive species, among other uses. The potential national security applications and implications of these technologies are equally profound, including protection of troops against infectious disease, mitigation of threats posed by irresponsible or nefarious use of biological technologies, and enhanced development of new resources derived from synthetic biology, such as novel chemicals, materials, and coatings with useful, unique properties.

Achieving such ambitious goals, however, will require more complete knowledge about how gene editors, and derivative technologies including gene drives, function at various physical and temporal scales under different environmental conditions, across multiple generations of an organism. In parallel, demonstrating the ability to precisely control gene edits, turning them on and off under certain conditions or even reversing their effects entirely, will be paramount to translation of these tools to practical applications…

Each of the seven teams will pursue one or more of three technical objectives: develop genetic constructs—biomolecular “instructions”—that provide spatial, temporal, and reversible control of genome editors in living systems; devise new drug-based countermeasures that provide prophylactic and treatment options to limit genome editing in organisms and protect genome integrity in populations of organisms; and create a capability to eliminate unwanted engineered genes from systems and restore them to genetic baseline states. Safe Genes research will not involve any releases of organisms into the environment; however, the research—performed in contained facilities—could inform potential future applications, including safe, predictable, and reversible gene drives….

A Harvard Medical School team led by Dr. George Church seeks to develop systems to safeguard genomes by detecting, preventing, and ultimately reversing mutations that may arise from exposure to radiation. This work will involve creation of novel computational and molecular tools to enable the development of precise editors that can distinguish between highly similar genetic sequences. The team also plans to screen the effectiveness of natural and synthetic drugs to inhibit gene editing activity.

A North Carolina State University (NCSU) team led by Dr. John Godwin aims to develop and test a mammalian gene drive system in rodents. The team’s genetic technique targets population-specific genetic variants found only in particular invasive communities of animals. If successful, the work will expand the tools available to manage invasive species that threaten biodiversity and human food security, and that serve as potential reservoirs of infectious diseases affecting native animal and human populations….

A University of California, Berkeley team led by Dr. Jennifer Doudna will investigate the development of novel, safe gene editing tools for use as antiviral agents in animal models, targeting the Zika and Ebola viruses. The team will also aim to identify anti-CRISPR proteins capable of inhibiting unwanted genome-editing activity, while developing novel strategies for delivery of genome editors and inhibitors….

A University of California, Riverside team led by Dr. Omar Akbari seeks to develop robust and reversible gene drive systems for control of Aedes aegypti mosquito populations.

Rivers as Legal Persons

The new law that declares the Whanganui river, New Zealand’s third-longest, a legal person, in the sense that it can own property, incur debts and petition the courts, is not unprecedented. Te Urewera, an area of forested hills in the north-east that used to be a national park, became a person for legal purposes in 2014….

The law, which was approved on March 15th, 2017 stems from disputes over the Treaty of Waitangi, by which New Zealand’s indigenous Maori ceded sovereignty to British colonialists in 1840. The treaty was supposed to have protected Maori rights and property; it was observed mainly in the breach. In recent years the government has tried to negotiate settlements for breaches of the treaty with different Maori iwi, or tribes. For the Whanganui iwi, the idea of the river as a person is nothing new. The iwi professes a deep spiritual connection to the Whanganui: as a local proverb has it, “I am the river and the river is me.” The law acknowledges the river as a “living whole”, rather than trying to carve it up, putting to rest an ownership dispute that has dragged on for 140 years. When it was passed, members of the iwi in the gallery of parliament broke into a ten-minute song of celebration.

In practice, two guardians will act for the river, one appointed by the government and one by the iwi. Mr Finlayson, the minister in charge of negotiations tied to the Treaty of Waitangi, hopes the change will help bring those who do environmental damage to the river to book. Under the settlement the government will also pay the iwi NZ$80m ($56m) as compensation for past abuses and set up a fund of NZ$30m to enhance the “health and well-being” of the river. It is one of 82 deals that aim to remedy breaches of the treaty, including one with the Tuhoe iwi that made Te Urewera into a person.

Days after the law passed, an Indian court declared two of the biggest and most sacred rivers in India, the Ganges and Yamuna, to be people too. Making explicit reference to the Whanganui settlement, the court assigned legal “parents” to protect and conserve their waters. Local lawyers think the ruling might help fight severe pollution: the rivers’ defenders will no longer have to prove that discharges into them harm anyone, since any sullying of the waters will now be a crime against the river itself. There is no doubt that of the 1.3bn-odd people in India, the Ganges and the Yamuna are among the most downtrodden.

Deforestation and Supply Chains

366 companies, worth $2.9 trillion, have committed to eliminating deforestation from their supply chains, according to the organization Supply Change. Groups such as the Tropical Forest Alliance 2020, the Consumer Goods Forum and Banking Environment Initiative aim to help them achieve these goals.  Around 70 percent of the world’s deforestation still occurs as a result of production of palm oil, soy, beef, cocoa and other agricultural commodities. These are complex supply chains.  A global company like Cargill, for example, sources tropical palm, soy and cocoa from almost 2,000 mills and silos, relying on hundreds of thousands of farmers. Also, many products are traded on spot markets, so supply chains can change on a daily basis. Such scale and complexity make it difficult for global corporations to trace individual suppliers and root out bad actors from supply chains.

Global Forest Watch (GFW), a WRI-convened partnership that uses satellites and algorithms to track tree cover loss in near-real time, is one example. Any individual with a cell phone and internet connection can now check if an area of forest as small as a soccer penalty box was cleared anywhere in the world since 2001. GFW is already working with companies like Mars, Unilever, Cargill and Mondelēz in order to assess deforestation risks in an area of land the size of Mexico.

Other companies are also employing technological advances to track and reduce deforestation. Walmart, Carrefour and McDonalds have been working together with their main beef suppliers to map forests around farms in the Amazon in order to identify risks and implement and monitor changes. Banco do Brasil and Rabobank are mapping the locations of their clients with a mobile-based application in order to comply with local legal requirements and corporate commitments. And Trase, a web tool, publicizes companies’ soy-sourcing areas by analyzing enormous amounts of available datasets, exposing the deforestation risks in those supply chains…

[C]ompanies need to incorporate the issue into their core business strategies by monitoring deforestation consistently – the same way they would track stock markets.

With those challenges in mind, WRI and a partnership of major traders, retailers, food processors, financial institutions and NGOs are building the go-to global decision-support system for monitoring and managing land-related sustainability performance, with a focus on deforestation commitments. Early partners include Bunge, Cargill, Walmart, Carrefour, Mars, Mondelēz, the Inter-American Investment Corporation, the Nature Conservancy, Rainforest Alliance and more.  Using the platform, a company will be able to plot the location of thousands of mills, farms or municipalities; access alerts and dashboards to track issues such as tree cover loss and fires occurring in those areas; and then take action. Similarly, a bank will be able to map the evolution of deforestation risk across its whole portfolio. This is information that investors are increasingly demanding.

Dams and Drought: the Amazon

The São Luiz do Tapajós (SLT) project… would dam one of the last big unobstructed tributaries of the Amazon. The project would provide about a third of the hydropower that Brazil plans for the forthcoming decade, but it would also flood 376 square km (145 square miles) of land where the Munduruku hunt, fish and farm. “The Tapajós valley is our supermarket, our church, our office, our school, our home, our life,” explained Mr Kabá.

The tussle over the Tapajós dam is part of a bigger fight about Brazil’s energy future. SLT is an example of a new sort of hydropower project, which floods a smaller area than traditional dams and therefore ought to cause less disruption and environmental damage. The massive Itaipu dam on the border with Paraguay inundated an area nearly four times as large. But critics of hydropower say “run of river” projects like SLT, which use a river’s natural flow to turn turbines, do not work as well as advertised. Though less destructive than conventional dams, which require bigger reservoirs, they still provoke opposition from people like the Munduruku. Other energy sources, such as gas and wind, are becoming more competitive. Brazil has “an opportunity” to rethink its energy policies, says Paulo Pedrosa, an energy official.

Hydropower has long been Brazil’s main way of generating electricity. Most forecasts suggest it will remain so. The government intends to build more than 30 dams in the Amazon over the next three decades. 

Climate change may worsen the problem. Some climate models predict that river flows in large parts of the Amazon will fall by 30% in coming decades. Deforestation is delaying the onset of the rainy season in some areas by six days a decade, according to research published in Global Change Biology, a journal.   Drought can be expensive. In 2014 power from conventional dams dipped because of a dry spell, forcing electricity companies to buy from gas- and coal-powered generators at high spot prices. The risk of such fluctuations rises with run-of-river dams. Carlos Nobre, a former chief of research at the ministry of science, technology and innovation, thinks more frequent droughts will make future hydropower projects in the Amazon unprofitable.

Brazil’s potential for solar and wind energy is among the highest in the world. The government has promoted them with lavish tax breaks. In the blustery north-east, wind power overtook hydropower this year; wind turbines now generate 36% of the region’s electricity, up from 22% in 2015. The Energy Research Company, a firm linked to the energy ministry, expects renewable generating capacity apart from hydropower to double by 2024.

Generators fuelled by natural gas have been hurt by the subsidies lavished on renewable energy. But, though less climate-friendly than hydropower, they are beginning to compete with it as a source of steady baseload electricity. Brazil now produces gas in abundance as a by-product of pumping oil from its offshore wells. Its marginal cost of production is nearly zero. The future of baseload energy is “hydro-thermal”, rather than hydro alone, says Adriano Pires of the Brazilian Infrastructure Centre, a think-tank in Rio de Janeiro.

Eviction and Property Rights in Africa

Evictions are almost routine for the Ogiek,  a group of around 80,000 indigenous hunter-gatherers who have suffered repeated expulsions since being moved by the British colonial government in the 1930s. Yet this one still came as a surprise: the community is in the middle of negotiating a settlement with the local government that should see formal recognition of its right to live, graze livestock and forage on land it has inhabited for centuries.

In all rich countries, property rights are secure. Formal, legal title makes it easier to buy, sell and develop land. Buyers can be confident that the seller really has the right to sell what he is selling. Owners can use their property as collateral, perhaps borrowing money to buy fertiliser and better seeds. Legally recognising land ownership has boosted farmers’ income and productivity in Latin America and Asia.

But not yet in Africa. More than two-thirds of Africa’s land is still under customary tenure, with rights to land rooted in communities and typically neither written down nor legally recognised. In 31 of Africa’s 54 countries, less than 5% of rural land is privately owned. So giving peasants title to their land seems like an obvious first step towards easing African rural poverty.

However, it has proven extremely hard. Rwanda, for example, rolled out a programme over three years, whereby local surveyors worked with land owners and their neighbours to demarcate and register 10.3m parcels of land…But even a relatively well-organised place like Rwanda has had problems keeping records up to date when land is sold or inherited.

In Kenya a large-scale titling programme was carried out in colonial times and carried over to independence. The first president, Jomo Kenyatta, and his cronies bought the huge estates of white settlers who left. But the system is costly and ill-run. Most Kenyans cannot afford to update titles, and the government has not maintained the registry. Recognising land rights, whether customary or titled, needs to be done as cheaply and simply as possible, says Ruth Meinzen-Dick of the International Food Policy Research Institute (IFPRI). “The more you increase the cost, the more likely it is that urban elites and men with more ed

Being able to prove you own your land may be a necessary condition for using it as collateral, but a title deed does not guarantee that anyone will lend you money. As Abhijit Banerjee and Esther Duflo, two economists, observe in their book “Poor Economics” (2011), banks need a lot more information to judge borrowers’ creditworthiness and be sure of repayment. And the administrative costs of offering very small loans to very small farmers, even those with collateral, are often prohibitive.

And legal property rights offer less protection in countries where big men can flout the law with impunity—a particular problem in Africa.  In recent years land grabs have sometimes made a mockery of customary ownership.

Owning and Trading Water

Rights regimes that are well designed and implemented are among the most effective tools for distributing water fairly and sustainably. Under one such system, Australian states began reforming water management in 1994. Few others have followed, though attempts at reform in Chile and Yemen have met with varying degrees of success.

To create tradable water rights, Australia first drew up a baseline for water use, taking into consideration past commercial, social and environmental needs. Next, old water rights were replaced with shares that granted holders (usually landowners) a proportion of any annual allocations. Clever formulae take account of the seniority of pre-existing rights. Different classes of shares determine who gets what and when to balance the competing claims of upstream farmers and downstream urbanites. After that a regulatory board makes sure that all users get as much as they are entitled to.

Allocations made to shareholders are tradable, but those receiving them can also store them for the future. This prevents any sudden wasting of water at the end of each year and encourages thrift during a drought. Issuing shares in perpetuity ensures that a holder can have more water only if someone else is prepared to have less. A centralised register holds everything together. Two markets for trading have been created: one in which shares are exchanged, and another for allocations of water in a given year. The idea is not a new one. In places such as Oman, aflaj systems involve villages trading in shares and in minutes of water flow.

Such regime change originally met strong resistance from farmers and other big users in Australia. But trading allocations reaped enormous rewards for shareholders. During the first decade of reform the annual internal rate of return from owning a water right was over 15%; those who held water shares saw the value of their rights double every five or so years. But following this example elsewhere will be tough. Even rich countries will struggle to unbundle rights that have accumulated over decades.

Loss of Giraffes

Over 700 newly recognised bird species have been assessed for the latest update of The IUCN Red List of Threatened Species, and 11% of them are threatened with extinction. The update also reveals a devastating decline for the giraffe, driven by habitat loss, civil unrest and illegal hunting. The global giraffe population has plummeted by up to 40% over the last 30 years, and the species has been listed as Vulnerable on the IUCN Red List.

Today’s IUCN Red List update also includes the first assessments of wild oats, barley, mango and other crop wild relative plants. These species are increasingly critical to food security, as their genetic diversity can help improve crop resistance to disease, drought and salinity…Almost every species of plant that humans have domesticated and now cultivate has one or more crop wild relatives. However, these species have received little systematic conservation attention until now.

The update was released today at the 13th Conference of the Parties to the Convention on Biological Diversity (CBD COP13) in Cancun, Mexico. The IUCN Red List now includes 85,604 species of which 24,307 are threatened with extinction. “Many species are slipping away before we can even describe them,” says IUCN Director General Inger Andersen.

Mining Rights on the Ocean Floor: phosphate

A persistent fear of diminishing phosphorus reserves has pushed mining companies to search far and wide for new sources. Companies identified phosphate deposits on the ocean floor and are fighting for mining rights around the world….

From April 2007 to August 2008, the price of phosphate, a necessary ingredient in fertilizer, increased nearly 950 percent, in part due to the idea that phosphate production had peaked and would begin diminishing. Before prices came back down, prospectors had already begun looking for deep sea phosphate reserves around the world.

Since then, the fledgling seabed phosphate industry has found minimal success. While several operations are proposed in the Pacific islands, New Zealand and Mexico rejected attempts at offshore phosphate mining in their territory.  This means southern African reserves – created in part by currents carrying phosphate-rich water from Antarctica – are the new center of debate.

Namibia owns identified seabed phosphate deposits, and the country has recently flip-flopped about whether to allow mining. A moratorium was in place since 2013, but in September 2016 the environmental minister made the controversial decision to grant the necessary licenses. Since then, public outcry forced him to set those aside…

Three companies, Green Flash Trading 251 (Pty) Ltd, Green Flash 257 (Pty) Ltd and Diamond Fields International Ltd., hold prospecting rights covering about 150,000 square kilometers, roughly 10 percent, of  South Africa’s marine exclusive economic zone…[G]reen Flash companies received drill samples, which showed current prices could not sustain seabed phosphate mining.

This leaves Diamond Fields as the only remaining player in South African waters. The company announced in a January 2014 press release that it received a 47,468 square kilometer prospecting right to search for phosphate.  According to information the company published summarising its environmental management plan, prospecting would use seismic testing to determine the benthic, or seafloor, geology. If mining commenced, it would take place on the seafloor between 180 and 500 meters below the surface.  “A vital and indisputable link exists between phosphate rock and world food supply,” the company stated, citing dwindling phosphate reserves…

Environmentalists argue that not only would phosphate mining destroy marine ecosystems, but it would also lead to continued overuse of fertilizers and associated pollution. They call for increased research into phosphate recapture technology instead of mining.“We could actually be solving the problem of too much phosphates in our water and recapturing it. Instead we’re going to destroy our ocean ecosystems,” John Duncan of WWF-SA said.

The act of offshore mining requires a vessel called a trailing suction hopper dredger, which takes up seafloor sediment and sends waste back into the water column.  “It amounts to a kind of bulldozer that operates on the seabed and excavates sediment down to a depth of two or three meters. Where it operates, it’s like opencast mining on land. It removes the entire substrate. That substrate become unavailable to fisheries for many years, if not forever,” Johann Augustyn, secretary of the South African Deep-Sea Trawling Industry Association, said….

Mining opponents also worry offshore mining would negatively impact food production and economic growth. Several thousand subsistence farmers live along South Africa’s coast, and the country’s large-scale fishing industry produces around 600,000 metric tonnes of catch per year.

“[Mining] may lead to large areas becoming deserts for the fish populations that were there. If they don’t die off, they won’t find food there, and they’ll probably migrate out of those areas,” Augustyn said.

South Africa is one of only three African nations – along with Namibia and Seychelles – implementing marine spatial planning. This growing movement toward organised marine economies balances competing uses such as oil exploration, marine protected areas and fisheries….[and mining.]

Survival of Tropical Forests: bird predators

[T]he Amazon rainforest contains more than 1,500 bird species. Around a quarter of them are found nowhere else on Earth. Many of these birds have evolved to fill a specific role – whether that means eating particular types of insects, or scattering a certain size of seed….A new paper published in Proceedings of the Royal Society explores  the link between deforestation in the Amazon and local bird diversity…[B]ird data was collected in 330 different sites in the Brazilian state of Pará, including arable and pastoral farmland and both primary and secondary forests. Primary forests are the original native vegetation, now increasingly degraded by logging and wild fires. Secondary forests are those which grow back in areas, often farmland, which have been abandoned by people…

The study focused on seed dispersal and insect predation, two ecosystem processes where birds play important roles. Fruit-eating (or frugivorous) birds spread the seeds of forest trees. Insect-eating (insectivorous) birds ensure that any germinating saplings have a fighting chance at survival. ..[S]witching from primary tropical forests to farmland dramatically reduced the “services” birds were able to provide.

This may seem fairly intuitive so far, given that there is a world of difference between a forest and cattle pasture. However, more significantly it was found that the traits were only partially restored in regenerating secondary forests. These areas have been branded as the “forests of the future” but we found them coming up short. These “forests of the future” cannot conserve all the biological interactions realised in primary forests, undisturbed or otherwise, which are essential for biodiversity conservation.  Once large seed-dispersing birds such as guans or cotingas are lost in an area, trees species with large seeds find it harder to recover. Regeneration becomes unlikely or impossible. Research from Brazil’s coastal Atlantic Forest has shown that the loss of such key species is driving the evolution of palm trees with smaller seeds. Some of these links may have been lost before we even knew them….The sorts of generalist insect-eaters that come to dominate farmland aren’t generally able to capture the well-disguised insects found in adjacent patches of forest.

The Manipulation of Insects: DARPA

DARPA’s Biological Technologies Office is working on new Insect Allies program. Insect Allies will seek to develop vector[insect]-mediated modification technologies for mature plants to rapidly counter environmental and biological threats to crops. Threats might include pathogens, pests, drought, and salinity, among others. DARPA believes that the high specificity of genetic modification coupled with quick plant gene uptake could allow crops to be protected from threats within a single growing season.The Proposers Day will be held on November 18, 2016

Keep Forests Standing: the forests bond

Launched on November 1, 2016, the Forests Bond will provide investors the opportunity to invest in a traditional financial product that offers the unique option of receiving interest payments in the form of environmental impact — in this case, verified carbon credits generated through REDD, an initiative that rewards landholders for protecting forests, thereby reducing carbon emissions that worsen climate change. The development of the bond is a collaboration of the International Finance Corporation (IFC), a member of the World Bank Group, and BHP Billiton with technical support from Baker & McKenzie and Conservation International (CI).

REDD (short for Reducing Emissions from Deforestation and forest Degradation), which offers financial incentives to landholders in tropical countries to keep their forests standing, has met with mixed success since its launch in 2005, in part because the lack of a carbon market left it dependent on voluntary action and bereft of the certainty needed to attract private funding.

“If you look at the scale of the problem, roughly US$ 100 billion to 300 billion needed to cut deforestation by half over the next decade, it’s clear that we need to mobilize private institutional investors, who control vastly greater amounts than public or philanthropic aid can deliver,” said Agustin Silvani, Conservation International’s vice president of conservation finance. “The REDD mechanism has mostly excluded them because it required specific carbon expertise or a specific interest in forests to engage with it.”

The Forests Bond supports a REDD project in Kenya, and investors can choose between a cash or carbon credit coupon (the interest received from the bond), or a combination of both. This unique element of the bond is made possible by the price support that BHP Billiton**is providing, which means that investors can either 1) elect to take the carbon credits to offset corporate greenhouse gas emissions or 2) sell them on the carbon market, or 3) take a traditional financial return instead. This provides the certainty needed to attract institutional investors while still generating verified reductions in deforestation, in the form of REDD credits…

The REDD project that the Forests Bond will support takes place in the Kasigau Corridor in eastern Kenya….Forest protection activities include forest and biodiversity monitoring, funding for community wildlife scouts, forest patrols, social monitoring and carbon inventory monitoring. Community development activities include reforestation of Mount Kasigau; establishment of an eco-charcoal production facility; support to community-based organizations; and expanding an organic clothing facility.

The bond is listed on the London Stock Exchange and has raised US$152 million from institutional investors.

**BHP Billiton is providing a price support mechanism of US$12 million that ensures that the project can sell a pre-defined minimum quantity of carbon credits every year until the Bond matures, whether or not investors in the Bond elect to receive carbon credit coupons.

Water Scarcity: the case of Tasmania

Australia is the world’s driest continent. Climate change is expected to make its droughts even more frequent. The country is still paying for years of overexploitation of its biggest river system, the Murray-Darling basin. The federal government in Canberra is spending A$3.2 billion ($2.2 billion) buying up and cancelling farmers’ water entitlements in a bid to reduce salinity and repair other environmental damage stretching back a century.

While mainland farmers are being paid to give up water, those in wetter Tasmania are being enticed to buy more. The island state accounts for just 1% of Australia’s land mass and 2% of its population. Yet it receives 13% of the country’s rainfall. Tasmania may be blessed with water, but most of it falls in the mountains of the west, making it useless to farmers elsewhere.

So the island has embarked on a project to capture more water for its drier east and north, shifting it through pipes to these regions’ farms. Almost 800 farmers have already bought into ten irrigation schemes that are up and running. They will allow farmers to do more than graze sheep and cattle; they will be able to grow fruit and vegetables, including more of Tasmania’s exotic stuff: cherries, grapes for the island’s increasingly fashionable wines and even poppies (the island is a big opium supplier for legitimate pharmaceuticals).

If another five planned schemes involving 200 farmers go ahead, Tasmania’s investment in shifting its water around the island will be almost A$1 billion. The federal and Tasmanian governments are putting up some of the money. But that comes with conditions. Farmers and other investors must first agree to meet at least two-thirds of the costs of each irrigation project before governments commit the rest….

Tasmania’s new water market has already been kind to one of its biggest investors. David Williams, a Melbourne banker, owns no Tasmanian farms. But he put A$10m into two central Tasmania irrigation schemes after local farmers had bought in. Mr Williams likens the arrival of reliable water in such regions to technological change: “I punted that it would change the way land is used.” He calculates that trading his water entitlement with farmers in both schemes could turn his investment into A$16m….

Among the foreign tourists coming to sample Tasmanian Riesling, oysters and marbled beef are plenty of Chinese. When China’s president, Xi Jinping, visited Hobart in late 2014, he sent signals that China wanted more seafood, beef and other costlier food exports from Tasmania.

Water Scarcity in West Bank and Gaza

[M]ost of Israel’s water is artificially produced. About a third comes from desalination plants that are among the world’s most advanced. Farmers rely on reclaimed water for irrigation. Israel recycles 86% of its wastewater, the highest level anywhere; Spain, the next best, reuses around 20%.

West Bank: None of these high-tech solutions helps the Palestinians [in the West Bank,] though, because they are not connected to Israel’s water grid. They rely on the so-called “mountain aquifer”, which lies beneath land Israel occupied in 1967. The 1995 Oslo Accords stipulated that 80% of the water from the aquifer would go to Israel, with the rest allocated to the Palestinians. The agreement, meant to be a five-year interim measure, will soon celebrate its 21st birthday. During that time the Palestinian population in the West Bank has nearly doubled, to almost 3m. The allocation has not kept pace.

The settler population has doubled too, and they face their own shortages. In Ariel, a city of 19,000 adjacent to Salfit, residents experienced several brief outages this month. Smaller settlements in the area, which are not hooked up to the national grid, have dealt with longer droughts. Palestinians have suffered far more, however. On average they get 73 litres per day, less than the 100-litre minimum recommended by the World Health Organisation.

The situation is even worse in Gaza, which relies almost entirely on a fast-shrinking coastal aquifer; what remains is polluted from years of untreated sewage and agricultural run-off. The stuff that comes out of Gazan taps is already brackish and salty. UN experts think that aquifer will be irreversibly damaged by 2020.

Israel’s water authority sells the Palestinians 64m cubic metres of water each year. It says they cause their own shortages, because up to a third of the West Bank’s water supply leaks out of rusting Palestinian pipes. A joint water committee is supposed to resolve these issues, but it has not met for five years…

Forest Fires and Haze

In 2015 a dry spell caused by the El Niño weather pattern made Indonesia’s forest fires especially severe. Smoke settled over Singapore for months and even reached Cambodia, Vietnam and the Philippines. At least 2m hectares of forest were burned. Dozens of people were killed and hundreds of thousands sickened. For much of October 2015 greenhouse gases released by those fires exceeded the emissions of the entire American economy. The losses over five months of fires amounted to around 2% of the country’s GDP…[The event has labeled  the 2015 Southeast Asian haze]

Between 2001 and 2014, Indonesia lost 18.5m hectares of tree cover—an area more than twice the size of Ireland. In 2014 Indonesia overtook Brazil to become the world’s biggest deforester.

One of the reasons for those forest fires is economic. The country produces well over half the world’s palm oil, a commodity used in cooking and cosmetics, as a food additive and as a biofuel. It accounts for around 4.5% of Indonesia’s GDP, and demand is still rising. To meet it, Indonesian farmers set fires to clear forest and make way for new plantations. Often these forests grow on peatlands, which store carbon from decayed organic matter; in tropical regions these hold up to ten times as much carbon as surface soil. Draining peatlands releases all of that carbon. The peat also becomes a fuel, so it is not just felled trees that are burning but the ground itself.

But politics also plays a part. … The president declared a moratorium on peatland-development licences and called for peat forests to be restored, even as his agriculture minister pointed out that burned peatland can be used for corn and soyabean planting….

Civil-society groups have had some success. At least 188 Indonesian palm-oil companies have made some sort of sustainability pledge, including five large multinational firms that in 2014 signed the Indonesian Palm Oil Pledge (IPOP), which commits them to avoiding deforestation and planting oil palms on peatland. Together those five firms account for 80% of Indonesia’s palm-oil exports.All the same, deforestation continues. Perversely, it may even have increased temporarily, as companies cleared as much land as they could before the agreement took effect. Besides, opaque supply chains allow companies to buy palm oil from suppliers not bound by IPOP.

Land Scarcity: Nigeria

Muslim herdsmen fleeing Boko Haram jihadists and fast-spreading desertification in the north of Nigeria are clashing with Christian farmers in the south, adding a dangerous new dimension to the sectarian tensions and militancy plaguing the country.

Thousands of people from Muslim Fulani tribes have moved southwards this year, leading to a series of clashes over land that have killed more than 350 people, most of them Christian crop farmers, according to residents and rights activists.

The fighting threatens to fracture the country further by bolstering support for a Christian secessionist movement in the south-east, which has been lingering for decades but gained fresh momentum late last year when resentment over poverty and the arrest of one of its leaders spilled over into street protests… [The Christian South] is campaigning  for an independent Biafra. They say they want to stop the Muslim north from dominating the Christian south…..The population of poverty-stricken Nigeria is expected to more than double to almost 400 million by 2050, according to the United Nations.y.

In one of the deadliest clashes, about 50 people were killed in April when Fulanis attacked the village of Nimbo in the south-eastern state of Biafra, according to residents, rights groups and lawmakers who visited Nimbo after the violence.

The Eradication of Rosewood: deforestation

On May 13th, 2016 hoping to save his country’s dwindling forests, Thongloun Sisoulith, the new prime minister of Laos, banned all timber exports. A government representative says environmental protection is among its top priorities. But a report to be published on June 24th, 2016  by the Environmental Investigation Agency (EIA), an NGO, suggests the clampdown will not be implemented by local officials—and even if it is, may come too late to save Siamese rosewood from being eradicated in Laos and Cambodia.

Much like the trade in rhino horn and tiger skins, trade in rosewood is driven by demand from China’s burgeoning middle classes for goods once reserved for the rich: in this case, hongmu, or “redwood”, furniture made in the ornate Qing-dynasty style. Siamese rosewood is among the most highly prized of the 33 types of tree used to make hongmu.

Five years ago Thailand had roughly 90,000 Siamese rosewood trees—more than anywhere else in the world. But the EIA says “significant volumes, if not most” of those trees were illegally chopped down before trade in Siamese rosewood became regulated under the Convention on International Trade in Endangered Species (CITES), a treaty.

That grim history seems to be repeating itself in Laos and Cambodia. Between June 2013 and December 2014 Vietnam and China (including Hong Kong) imported more than 76,000 cubic metres of Siamese rosewood—more than the total amount growing in Thailand in 2011. Jago Wadley of the EIA says that Vietnam is a conduit through which the wood enters China. Of the total amount imported, 83% came from Laos and 16% from Cambodia.

Documentation accompanying the imported wood showed that 85% was harvested in the wild. Corrupt local officials have failed to enforce the restrictions imposed by the central Lao and Cambodian governments. Middlemen pay villagers to cut down the trees; they then sell the timber to Chinese or Vietnamese businessmen.

Illegal Genetically Modified Crops: China

In 2013 President Xi Jinping of China…recounted his own experience of hunger during China’s great famine in the early 1960s…..He said that guaranteeing China’s “food security” was still a serious worry. Hinting at what he saw as a possible remedy, he said China must “occupy the commanding heights of transgenic technology” and not yield that ground to “big foreign firms”….

Since then, however, Chinese policy had grown much more conservative, for two main reasons. The first is anxiety among some members of the public about the safety of GM foods. The other is a worry that China’s food market might become reliant on foreign GM technology. True, a large share of the soyabeans imported by China are genetically modified. So is the vast majority of the cotton it grows. In 2015 there were more than 6.6m farmers growing GM cotton, and a total of 3.7m hectares of GM crops under cultivation, including cotton and papaya, according to Randy Hautea of the International Service for the Acquisition of Agri-biotech Applications, an industry group. But the government has been reluctant to approve the growing of GM staples such as maize (corn) and rice.   …

Worries about foreign domination of GM technology may ease if a $43 billion deal reached in February 2016 goes ahead for the takeover of Syngenta, a Swiss agricultural firm, by a Chinese company, ChemChina. The acquisition must still be approved by regulators in several countries, but it could give China control of Syngenta’s valuable GM-seed patents.

China’s policymakers may be trying to bring belated order to what is already thought to be the widespread, illegal, growing of GM crops. Greenpeace, an NGO, reported in January 2016 that 93% of samples taken from maize fields in Liaoning province in the north-east tested positive for genetic modification, as did nearly all the seed samples and maize-based foods it gathered at supermarkets in the area.

Defenses Against the Sea: Bangladesh

Facing the bleak prospect of millions of its citizens being displaced in coming years due to storms and sea level rise caused by climate change, Bangladesh is building up existing coastal embankments in a bid to protect coastal lands and people. On November 2015, the Bangladesh Water Development Board (BWDB) signed a deal with the Chinese firm First Engineering Bureau of Henan Water Conservancy to start work on the Coastal Embankment Improvement Project-1… And as per the agreement, the Chinese firm is helping rebuild four polders in two coastal districts – Khulna and Bagerhat.

Bangladesh is a low-lying delta, making it one of the most vulnerable countries to climate change. The coastal region adjoining the Bay of Bengal is characterised by a vast network of active tidal rivers. The strength of the tides and the flatness of the delta causes the tides to influence river processes a long way upstream in the southern estuaries. And climate change has intensified the tides in recent years.

“We will repair all 139 coastal polders considering the climate-induced changes presumed to take place by 2050 to protect coastal people from recurrent climatic disasters like cyclone and storm surge,” Water Resources Minister Anisul Islam Mahmud told IPS.  He said the water development board is currently working to rebuild 17 coastal embankments in its first phase, and the remaining polders will be repaired gradually.

The Coastal Embankment Improvement Project Phase-1 (CEIP-1) involving 400 million dollars to rebuild 17 polders in six coastal districts – Khulna, Satkhira, Begerhat, Pirojpur, Barguna and Patuakhali. The height of 200-kilometre-long embankments will be increased by one to two metres and 58 regulators will be set up in the first phase.

Since the 1960s, Bangladesh built 139 polders to protect about 1.2 million hectares of land from seawater…

Water: the White Gold

Considered as the “white gold” –as opposed to the “black gold”—oil, water scarcity has become one of the major concerns of Bahrain in spite of the fact that it has a high Human Development Index and was recognized by the World Bank as a high-income economy.  It’s Gross Domestic Product (GDP) per capita amounts to 29,140 US Dollars. And it is home to the headquarters for the United States Naval Forces Central Command/United States Fifth Fleet.

All the above does not suffice to make Bahrainis happy. In fact, their country leads the list of 14 out of the 33 countries most likely to be water-stressed in 2040 –all of them situated in the Middle East– including nine considered extremely highly stressed according to the World Resources Institute (WRI).  After Bahrain comes Kuwait, Lebanon, Palestine, Oman, Qatar, Saudi Arabia, and the United Arab Emirates.  Other Middle East Arab countries more or less share with Bahrain this front line position of water-stressed states. These are Algeria, Iraq, Jordan, Libya, Morocco, Syria, Tunisia and Yemen. All of them hold a very close second position in the region’ s water-stress ranking. The total represents two thirds of the 22 Arab countries. Not that the remaining Arab states are water-safe. Not at all: Mauritania, in the far Maghreb West, and Egypt, at the opposite end, are already under heavy threat as well.

The whole region, already arguably the least water-secure in the world, draws heavily on groundwater and desalinated sea water, and faces exceptional water-related challenges for the foreseeable future, says the WRI’s report: Ranking the World’s Most Water-Stressed Countries in 2040. The report’s authors Andrew Maddocks, Robert Samuel Young and Paul Reig foresee that world’s demand for water, including of course the Middle East, is likely to surge in the next few decades…This comes at a time when the Arab region has not taken advantage of its water resources of about 340 billion cubic meters, using only 50 per cent. The rest is lost and wasted.

Regarding the North of Africa, the Egyptian Ministry for Environment has recently admitted that large extensions of the country’s Northern area of the Nile Delta, which represents the most important and extensive agricultural region in Egypt, is already heavily exposed to two dangerous effects: salinasation and flooding. This is due to the rise of the Mediterranean Sea water levels and the land depression.

The impact of global warming and growing heat waves is particularly worrying the Egyptian authorities as it might reduce the flow of the Nile water in up to 80 per cent according to latest estimates

Monsanto in India, the royalties

Monsanto Co, the world’s biggest seed company, threatened to pull out of India on March 2016 if the government imposed a big cut in royalties that local firms pay for its genetically modified cotton seeds.

Mahyco Monsanto Biotech (India)(MMB), a joint venture with India’s Mahyco, licenses a gene that produces its own pesticide to a number of local seed companies in lieu of royalties and an upfront payment. MMB also markets the seeds directly, though the local licensees together command 90 percent of the market.  Acting on complaints of local seeds companies that MMB was charging high fees, the farm ministry last year formed a committee to look into the matter.

The committee has now recommended about a 70 percent cut in royalty, or trait fee, that the seed companies pay to MMB, government sources said. The farm ministry is yet to take a decision on the committee’s recommendation.  “If the committee recommends imposing a sharp, mandatory cut in the trait fees paid on Bt-cotton seeds, MMB will have no choice but to re-evaluate every aspect of our position in India,” Shilpa Divekar Nirula, Monsanto’s chief executive for the India region, said in a statement…

Separately, MMB has filed a case in a Delhi court, challenging the authority of the committee to determine the trade fee agreed upon by MMB and a number of Indian seed companiesIn a partnership with Mahyco, U.S.-based Monsanto launched a GM cotton variety in India in 2002 despite opposition from critics who questioned its safety, helping transform the country into the world’s top producer and second-largest exporter of the fiber.

In a ruling on Feburary 2016, the Competition Commission of India, the antitrust regulator, said there were indications that MMB had abused its dominant position in the country and asked its director general to complete an investigation within two months.  The government-appointed committee has also recommended cutting Bt cotton seed prices to about 800 rupees for a packet of 400 grams. Currently Bt cotton seeds are being sold between 830 and 1100 rupees in different parts of the country.

Miners v. Indigenous Peoples: Canada

In 1849 the First Nation of Ojibways, a Canadian indigenous group, fired a cannon into a copper mine that had gone ahead without their approval.These days Canada’s aboriginal groups use public pressure, backed by legal action, to protect their lands against exploitation by outsiders. In February 2016 the government of British Columbia reached agreement with forest companies, environmental groups and 26 First Nations communities to protect from logging an area on the Pacific coast larger than Belgium—newly dubbed the Great Bear Rainforest. The deal, which allows logging and mining in areas aboriginals have agreed to, is the culmination of a long public-relations campaign (choosing the Kermode bear as its mascot was a masterstroke). It would have got nowhere without centuries of treaty-making and decades of case law to back it up….

The federal aboriginal affairs agency is party to 554 proceedings involving such rights (not all of which concern resource firms). That does not include disputes between aboriginal groups and firms. Projects as diverse as seismic testing for mineral deposits in Arctic waters and fracking in the west face challenges. Until 1951 such lawsuits were barred. They are expensive and can drag on for years; the outcome is never assured. The Tsilhqot’in, who filed suit in 1998 against logging on their ancestral lands in British Columbia, finally won in 2014 and now have title to 1,750 square km (1,100 square miles). But the Innu of Ekuanitshit in Quebec last year lost their bid to stop the Muskrat Falls hydropower project, which they say will affect caribou herds.

Some big projects are caught in legal limbo. The Northern Gateway pipeline, which is to bring crude oil from Alberta to Canada’s west coast, has been stalled for more than a decade, largely because of opposition from First Nations groups along its route, some of them parties to the Great Bear agreement. The Pacific Northwest liquefied natural gas project, backed by Petronas, a Malaysian state-owned firm, has offered C$1 billion ($726m) in benefits over 40 years to the Lax Kw’alaams nation of northern British Columbia. That has not allayed fears that the project would destroy salmon fisheries.

When such disputes are unresolved, the price can be high. The Northern Gateway pipeline would add C$300 billion to Canada’s GDP over 30 years.

Coral Reefs Preservation: Aichi Targets

In the past half-century, though, these beautiful, biodiverse structures have been put under pressure by human activity. About a quarter of all coral cover has died. The reefs that are in worst shape are those off the most crowded beaches. “People don’t leave enough time for their sun cream to soak in, so it gets in the water,” says one deckhand with Eo Wai’anae Tours, which organises boat trips off Oahu. More damage is caused by fertiliser-rich run-off from farms, leading to algal blooms which block light the corals need. Fishing near reefs cuts the number of herbivorous fish, allowing vegetation to grow out of control. Some fishing methods are particularly harmful: for example, blast fishermen in Colombia, Tanzania and elsewhere use dynamite to stun and kill fish without regard to the harm done to nearby reefs…In the South China Seaisland-building and fishing for giant clams are crushing some reefs beyond the possibility of recovery (seearticle)….

Tourism generated by the Great Barrier Reef is worth about $4.6 billion annually to nearby Queensland alone. Australian bigwigs bent over backwards last year to keep the UN from listing the reef, a World Heritage Site, as “in danger”. Estimates suggest that the economic value of Martinique and Saint Lucia’s corals comes to $50,000 per square km each year, thanks largely to tourism. But overdevelopment threatens the reefs the visitors come to gawp at. Sediment from construction clouds waters, burying corals and blocking the light they need. Hotels close to the shore may be convenient for tourists, but the process of building them can kill the reefs that snorkellers like to swim over…The three countries with the largest numbers of people who fish on reefs are all in the coral-triangle region: Indonesia, Papua New Guinea and the Philippines. In Indonesia and in the Philippines, up to 1m people’s livelihoods depend on reefs.

Averting a tragedy of the commons means agreeing which activities should be restricted and enforcing the rules. For coral reefs—and other biodiverse marine environments—the usual approach is to give ecologically sensitive areas special status under local or regional laws. In such “marine protected areas” (MPAs), activities that are deemed harmful, such as fishing, drilling and mining, can then be restricted or banned, with penalties for rule-breakers.

The Aichi targets, agreed in 2010 under the UN Convention on Biological Diversity, seek to reduce “anthropogenic pressures” on coral reefs to “maintain their integrity and function”. The aim is to have at least 17% of inland water and 10% of coastal and marine areas under conservation by 2020. Most countries have signed up. But the targets are far from being met. Less than 3% of the ocean’s surface is within an MPA.

The most urgent action is needed close to shore. The nearer humans are to reefs, the worse their effect on the fragile ecosystems. A global register of fishing vessels, long under discussion, would also help identify wrongdoers. And beefing up the UN law of the sea could inspire further action. Decades old, it has little to say about biodiversity.

But simply declaring an area protected does not make it so. In 2009 George Bush junior, then president of America, established three national marine monuments in the Pacific, including nearly 518,000 square km of coral islands and surrounding areas. Their remoteness makes it hard to stop vessels entering illegally; Hawaii’s coastguard is already stretched.

Satellites are sometimes used to police MPAs, but they pass over infrequently. In the future, sailing robots could play a larger role. America’s National Oceanic and Atmospheric Administration (NOAA) has been working with a private firm, Saildrone, on hardy models equipped with carbon-fibre fins. They cost less than $500,000 each and can roam remote ocean regions for months, making them far cheaper than manned boats.

Such drones could photograph rogue fishing vessels, obtaining hard-to-gather evidence for any criminal proceedings. And they could carry out other useful work at the same time, such as monitoring ocean temperature and acidity or tracking tagged members of endangered species. Saildrone plans to provide its robots as a service, so that universities and other cash-strapped organisations do not have to buy one outright…

Even if the right policies are adopted to keep corals healthy in the immediate future, longer-term threats loom. Neither oceanic warming nor acidification can be kept out by an MPA. And both may be happening too fast for corals to adapt, especially as recent global climate deals will not slow them much. Back slaps and handshakes accompanied the inclusion of an aim to limit global warming to just 1.5°C above pre-industrial levels in the Paris Agreement last year. But only an incorrigible optimist would bet on that aim being achieved.

So researchers are turning their attention to ways to help corals cope. Their global diversity, scientists hope, may hold the key. The same coral will grow differently under different conditions: corals of the western Pacific near Indonesia, for example, can withstand higher temperatures than the same species in the eastern Pacific near Hawaii….The characteristics that help some reefs survive unusual conditions could allow others to endure climate change. But tough corals from one place cannot simply be transplanted to another. So a team at the Hawaii Institute of Marine Biology is in the early stages of engineering reef ecosystems, with $4m from the Paul G. Allen Foundation, a charity set up by Bill Gates’s former business partner.

Organisms respond to environmental changes through both genetic processes (adaptation) and non-genetic ones (acclimatisation). With corals, the nature of their symbiotic relationships can also alter. So selectively breeding and conditioning them, and investigating whether certain types of algae confer resistance to heat or acidity, could create hardier varieties faster than they would develop naturally.

These could then be used to repopulate ravaged reefs—once more is known about how and where to transplant them. “We’re assisting evolution,” explains Ruth Gates, who leads the research.

Fishermen + Farmers Against Shell

Tens of thousands of Nigerian fishermen and farmers are suing multinational oil giant Shell in two new lawsuits filed on March 2, 2016 in a British High Court, alleging that decades of uncleaned oil spills have destroyed their lives.  London law firm Leigh Day & Co. is representing them after winning an unprecedented $83.5 million in damages from Shell in a landmark ruling by the same court last year. Shell originally offered villagers $50,000.

In a statement on March 2, 2016 before the trial opened, Shell blamed sabotage and oil theft for the ongoing pollution and noted it had halted oil production in 1993 in Ogoniland, the area where the two communities are located in Nigeria’s oil-rich southern Niger Delta.  Shell said it will challenge the jurisdiction of the British court.

The Ogoni are among the most traumatized of millions of Nigerians suffering oil pollution since the late 1950s….

Why Illegal Logging Persists

The European Union (EU) adopted in 2010 Regulation (EU) No 995/2010 laying down the obligations of operators who place timber and timber products on the market (the Timber Regulation,, as part of the implementation of the Action Plan on Forest Law Enforcement, Governance and Trade……[The EU adopted the Regulation because] llegal logging is a pervasive problem of major international concern. It has a devastating impact on some of the world’s most valuable remaining forests as well as on the people who live in them and who rely on the resources that forests provide. It contributes to tropical deforestation and forest degradation, which may be responsible for 7 to 14%3 of total CO2 emissions from human activities; it threatens biodiversity and undermines sustainable forest management and has a negative impact on poverty reduction…..

The following major challenges to the effective application of the Timber Regulation have been identified in the evaluation process: insufficient human and financial resources allocated to the [authorities dealing with implementation], varying types and level of sanctions across EU states and a lack of uniform understanding and application of the Regulation throughout the EU. Those challenges have translated into uneven enforcement, which creates a non-level playing field for economic operators….

In order to address the shortcomings identified, EU states should significantly step up their implementation and enforcement efforts. The current level of technical capacity and resources (both human and financial) allocated to the [authorities dealing with implementation] does not match with the needs and must be reinforced in most of the Member States with the aim to increase the number and quality of compliance checks.

Stealing Patent-Protected Seeds

A Chinese man pleaded guilty in a US court on January 27, 2016 to stealing patent-protected corn seed from agribusiness giants Monsanto and DuPont to take back to China for commercial use.  Mo Hailong, 46, participated in a plot to steal inbred corn seeds from the two US companies so that his then employer, Beijing Dabeinong Technology Group, could use them in its own seed business, the US Department of Justice said.Mo “admitted to participating in the theft of inbred – or parent – corn seeds from fields in the southern district of Iowa for the purpose of transporting those seeds to China,” the department said in a statement.“The stolen inbred seeds constitute the valuable intellectual property of DuPont Pioneer and Monsanto.”..

Dams on Nile: winners and losers

Egyptian politicians discussed sabotaging the Grand Ethiopian Renaissance Dam in 2013, they naturally assumed it was a private meeting. But amid all the scheming, and with a big chuckle, Muhammad Morsi, then president, informed his colleagues that their discussion was being broadcast live on a state-owned television channel.

Embarrassment apart, it was already no secret that Egypt wanted to stop the largest hydroelectric project in Africa. When Ethiopia completes construction of the dam in 2017, it will stand 170 metres tall (550 feet) and 1.8km (1.1 miles) wide. Its reservoir will be able to hold more than the volume of the entire Blue Nile, the tributary on which it sits. And it will produce 6,000 megawatts of electricity, more than double Ethiopia’s current measly output, which leaves three out of four people in the dark…

This boon for Ethiopia is the bane of Egypt, which for millennia has seen the Nile as a lifeline snaking across its vast desert. The river still provides nearly all of Egypt’s water. Egypt claims two-thirds of that flow based on a treaty it signed with Sudan in 1959. But even that is no longer enough to satisfy the growing population and sustain thirsty crops. Annual water supply per person has fallen by well over half since 1970. The UN warns of a looming crisis. Officials in Egypt, while loth to fix leaky pipes, moan that the dam will leave them high and dry.,,

Only recently has the Egyptian government adopted a more conciliatory tone. In March of last year Abdel-Fattah al-Sisi, who ousted Mr Morsi in a coup, joined Hailemariam Desalegn, Ethiopia’s prime minister, and Omar al-Bashir, Sudan’s president, to sign a declaration that tacitly blesses construction of the dam so long as there is no “significant harm” to downstream countries. The agreement was affirmed in December. 2015, when the three countries settled on two French firms to study the dam’s potential impact. The impact studies were meant to be completed last year, but bickering over the division of labour, and the withdrawal of one firm, caused delays. Many Egyptians believe that Ethiopia is stalling so that the dam becomes a fait accompli. Already half-finished, experts worry that it may be too late to correct any problems. Representatives of the three countries are now meeting to discuss “technical” issues. The contracts for studying the dam are not yet signed.

A sense of mistrust hangs over the dam’s ultimate use. Ethiopia insists that it will produce only power and that the water pushing its turbines (less some evaporation during storage) will ultimately come out the other side. But Egypt fears it will also be used for irrigation, cutting downstream supply.  …A more reasonable concern is over the dam’s large reservoir. If filled too quickly, it would for a time significantly reduce Egypt’s water supply and affect the electricity-generating capacity of its own Aswan Dam. But the Ethiopian government faces pressure to see a quick return on its investment. The project, which is mostly self-funded, costs $4.8 billion….

A potential wild card in the negotiations is Sudan, which long sided with Egypt in opposition to the dam, some 20km from its border. But as the potential benefits to Sudan have become clear, it has backed Ethiopia…Short on energy itself, Sudan will receive some of the power produced by the dam. By stabilising the Nile’s flow, it will also allow Sudan to prevent flooding, consume more water and increase agricultural output (once old farming methods are updated). Currently much of the country’s allocation of water under the 1959 treaty is actually consumed by Egyptians…

The Renaissance Dam is merely the latest test of countries’ willingness to share water. There may soon be more difficulties. Ethiopia plans to build other dams on the river, which could further affect downstream supply. Sudan has promised foreign investors an abundance of water for irrigation…

Lawsuits Against Shell, Nigeria

A Dutch appeals court ruled on December 18, 2015 that Royal Dutch Shell can be held liable for oil spills at its subsidiary in Nigeria, potentially opening the way for other compensation claims against the multinational. Judges in The Hague ordered Shell to make available to the court documents that might shed light on the cause of the oil spills and whether leading managers were aware of them.  This ruling overturned a 2013 finding by a lower Dutch court that Shell’s Dutch-based parent company could not be held liable for spills at its Nigerian subsidiary.

The legal dispute dates back to 2008, when four Nigerian farmers and the campaign group Friends of the Earth filed a suit against the oil company in the Netherlands, where its global headquarters is based.  “Shell can be taken to court in the Netherlands for the effects of the oil spills,” the court ruling stated on Friday. “Shell is also ordered to provide access to documents that could shed more light on the cause of the leaks.”  The case will continue to be heard in March 2016.  Judge Hans van der Klooster said the court had found that it “has jurisdiction in the case against Shell and its subsidiary in Nigeria”….

“There are 6,000km of Shell pipelines and thousands of people living along them in the Niger Delta,” he said. “Other people in Nigeria can bring cases and that could be tens of billions of euros in damages.”  In a separate case, Shell agreed in January to pay out £55m ($82 million) in out-of-court compensation for two oil spills in Nigeria in 2008, after agreeing a settlement with the affected community in the Delta.

Gene Banks: saving world’s crops

Syria’s civil war has forced scientists to request the first-ever withdrawal of seeds from a Doomsday vault built in the Arctic to safeguard the world’s food supplies…The International Center for Agricultural Research in the Dry Areas (ICARDA) said it has made a request to take back some of its samples from the Svalbard Global Seed Vault. The vault was created by the Norwegian government in 2008 to protect vital crops such as wheat against global disasters, war or disease.

It will be the first time seeds have been withdrawn from the facility, which lies more than 800 miles inside Arctic Circle — midway between Norway and the North Pole — and is the largest vault of its kind in the world. Built into the mountainside on the Svalbard archipelago, it relies on permafrost and thick rock to ensure that the seed samples will remain frozen even without power..,ICARDA has requested approximately 16,500 of its seed samples — one seventh of the total it has stored in Svalbard — and hopes to reproduce them at its other facilities in Morocco and the American University in Beirut, Lebanon. Eventually it will send new samples back to Norway…

He said some scientists were still present at the Aleppo facility but that its one-time headquarters had been occupied by armed groups.  “Fortunately it is not ISIS, they are some fundamentalist groups,” he said. “They seem to co-exist. They are using the land for their own benefit, for example to grow legumes, but we have no control of it…..The Svalbard seed bank has exactly 865,871 samples from every country in the world, Asdal said.  “In fact, we have seeds from more countries than now exist,” he explained, since some of the older seeds are from now-defunct nations such as Czechoslovakia. Syria’s civil war has killed a quarter of a million people since 2011, according to United Nations estimates, and driven 11 million more from their homes.

Weather Engineering and Climate Change

Maharashtra is one of the largest and wealthiest of India’s 30 states, with 110 million residents. It encompasses Mumbai and other large cities, plus vast swaths of farmland. Like other agricultural regions of India, it’s in its third consecutive year of drought. More than 80 percent of its farms depend on rain for irrigation, and agriculture production has dropped by almost a third since 2013. The human impact has been severe—1,300 debt-trapped farmers have committed suicide in Maharashtra in just the past six months.In July, 2015 the state’s minister of revenue, Eknath Khadse, took a gamble: He hired Koliwad to carry out a $4.5 million cloud-seeding program over three months and across 100 square miles in the middle of the state, the largest campaign of this kind ever attempted in India.

So Koliwad called Weather Modification Inc., the world’s largest private aerial cloud-seeding company, based in Fargo, N.D. WMI’s chief executive, Patrick Sweeney, developed a five-year technology transfer program with Koliwad that’s now in its first year. Pederson and other WMI staff are training Indian pilots, meteorologists, and Doppler radar technicians to seed clouds.

Sweeney has seeded clouds all over the world for more than 20 years, but the Maharashtra project is unique in that the circumstances are so dire. “The hardest part is managing expectations,” he says. “People in Maharashtra are hoping for a cure-all to drought. They come out and dance in the streets when it rains, they hug our pilots and say, ‘Do it again.’ But we can’t guarantee that the clouds will be there—and willing to cooperate.”..

Despite the uncertainty, the industry is on the rise. According to the World Meteorological Organization, more than 52 countries have active cloud-seeding operations—up from 42 four years ago. In the U.S. last year, 55 cloud-seeding projects were reported to NOAA. There’s even a luxury cloud-seeding market emerging—one European company, for instance, charges a minimum of $150,000 to guarantee good wedding weather by forcing clouds to rain in the days before the event….

Sweeney also built ICE (Ice Crystal Engineering), a company that makes cloud-seeding chemicals and supplies flares to 25 countries. ICE adds a decent sidestream of income for Sweeney, with revenue of about $3 million a year. But the bigger advantage is that it helped WMI become the only aerial seeding company that “does a full turnkey,” says Neil Brackin, WMI’s president—meaning it customizes and operates the planes and radars, manufactures the flares, and flies the missions.

They do have competitors. There are 34 private companies worldwide that do weather modification, but there’s no bigger rival in aerial cloud seeding than the Chinese government, which spends hundreds of millions a year seeding clouds in 22 of its 23 provinces, both to clear pollution above cities and to enhance rainfall for farming. China has yet to allow private companies to enter its market, but Sweeney is making inroads; he sold his first cloud-seeding plane to Beijing last year.

Thailand’s government has a Bureau of Royal Rainmaking, with hundreds of employees that WMI helped train, though the program’s still using old technology—releasing mounds of table salt from trap doors in the bellies of its planes. And when the Argentine government took over the cloud-seeding program WMI built for the country, it cut costs. Soon after, two pilots died seeding clouds above a mountain, and the project was suspended…

Brackin adds that while scientists want to achieve a 99.99 percent probability that a technology consistently works, the industry doesn’t need that kind of certainty or consistency to succeed. He likens cloud seeding to a cutting-edge medication that’s still in development: “If you’re dealing with a serious ailment and you were offered a medicine that had a 60 percent chance of working, or even 20 percent, would you take it? You probably would.”

Climate Change 2015

 

Global carbon emissions were 58% higher in 2012 than they were in 1990. The atmospheric concentration of carbon dioxide has risen from just under 340 parts per million in 1980 to 400 in 2015.  To stand a fair chance of keeping warming to just 2°C by the end of the century—the goal of global climate policy—cumulative carbon emissions caused by humans must be kept under 1 trillion tonnes. Estimates vary but, according to the Intergovernmental Panel on Climate Change, the total had hit 515 billion tonnes by 2011. Climate Interactive, a research outfit, reckons that if emissions continue on their present course around 140 billion tonnes of greenhouse gases will be released each year and temperatures could rise by 4.5°C by 2100. And even if countries fully honour their recent pledges, temperatures may still increase by 3.5°C by then.

The world is already 0.75°C warmer than before the Industrial Revolution….

Melting glacier ice, and the fact that warmer water has a larger volume, mean higher sea levels: they have already risen by roughly 20cm since 1880 and could rise another metre by 2100. That is perilous for low-lying islands and flat countries: the government of Kiribati, a cluster of tropical islands, has bought land in Fiji to move residents to in case of flooding. Giza Gaspar Martins, a diplomat from Angola who leads the world’s poorest countries in the climate talks, points out that they are particularly vulnerable to the effects of a warming planet. Money alone, he argues, will not fix their problems. Without steps to reduce emissions, he predicts, “there will be nothing left to adapt for.”…

For every 0.6°C rise in temperature, the atmosphere’s capacity to hold water grows by 4%, meaning storms will pour forth with greater abandon. The rains of the Indian monsoon could therefore intensify, cutting yields of cereals and pulses.

Climate change seems also to be making dry places drier, killing crops and turning forests into kindling. Forest fires in Indonesia, more likely thanks to the current El Niño weather phenomenon, could release 2 billion tonnes of carbon dioxide, about 5% of annual emissions due to human activity, says Simon Lewis of University College London. In recent months fires have swallowed more than 2.4m hectares of American forests. Alaska suffered 80% of the damage—a particular problem because the soot released in these blazes darkens the ice, making it less able to reflect solar radiation away from the Earth.

Developments in the Arctic are worrying for other reasons, too. The region is warming twice as fast as the rest of the world, a trend that could start a vicious cycle. Around 1,700 gigatonnes of carbon are held in permafrost soils as frozen organic matter. If they thaw, vast amounts of methane, which is 25 times more powerful as a global-warming gas than carbon dioxide when measured over a century, will be released. One hypothesis suggests that self-reinforcing feedback between permafrost emissions and Arctic warming caused disaster before: 55m years ago temperatures jumped by 5°C in a few thousand years…

And on September 29th Mark Carney, the governor of the Bank of England, warned that though measures to avoid catastrophic climate change are essential, not least for long-term financial stability, in the shorter term they could cause investors huge losses by making reserves of oil, coal and gas “literally unburnable”.

The Costs of Stopping Biopiracy

Botanists think there are up to 80,000 wild species of flowering plant left to discover. But a scarcity of funds hampers efforts to collect them. The UN Convention on Biological Diversity of 1992, ratified by 195 states and the European Union, made things more complicated. It recognised plants as part of countries’ national heritage and outlawed “biopiracy”—profiting from plants without compensating the countries in which they were found.

That made exploiting plants fairer but collecting them harder. Some officials saw a chance to get rich. “Suddenly everyone thought these plants were incredibly valuable,” says Mr Hawtin. Getting permission to go on a collecting trip became nearly impossible. “Anybody could say no to a collecting expedition and very few people could say yes.”

Permits became sine qua non, but in poorer countries the environment ministries that were expected to issue them did not always exist. Collectors might see their applications bounced from one department to another, each unwilling to wield its rubber stamp. “No one wanted to be accused in their local paper of helping the biopirates,” says Mr Hawtin.

Persistent botanists have since earned some governments’ trust. It is now much easier to get approval for expeditions than it was in the 1990s, though often with restrictions on what may be collected. “Things are much better now than they were ten years ago,” says Sandy Knapp, head of the plants division at the Natural History Museum in London. A three-year permit from the Peruvian government allows her to collect specimens of Solanaceae, the family that includes tomatoes, potatoes and aubergines…The Millennium Seed Bank now holds workshops in many countries on collection and conservation techniques. It collaborates on expeditions and produces guidebooks to help locals locate and collect seeds for themselves. Yet some countries persist in imposing self-defeating restrictions. India’s biodiversity law, passed in 2002, makes exporting seeds very difficult and sits poorly with its international obligations. If governments fail to understand the urgency of preserving—and sharing—their biodiversity, there may soon be precious little left to collect.

Making Money in the Peruvian Amazon

The Sierra del Divisor region in the Peruvian Amazon was identified as a biodiversity conservation priority back in the early 1990s. More than 20 years later and Peruvians are still waiting – some more desperately than others given all the narco-traffickers, illegal loggers and gold-miners in or near the region.

What’s so special about the Sierra del Divisor? It’s the “only mountainous region” anywhere in the lowland rainforest, according to Peruvian NGO Instituto del Bien Comun (IBC), while The Field Museum, in the US, describes it as “a mountain range” rising up “dramatically from the lowlands of central Amazonian Peru” and boasting “rare and diverse geological formations that occur nowhere else in Amazonia.” Its most iconic topographical feature is “El Cono”, an extraordinary peak visible from the Andes on a clear day.

Sierra del Divisor is home to numerous river headwaters feeding into key Amazon tributaries, eco-systems, and a tremendous range of flora and fauna, some of which are endemic, some endangered or threatened – and some with the most wonderful names. Giant armadillos, jaguars, cougars, Acre antshrikes, curl-crested aracaris, blue-throated piping guans and various kinds of monkeys, including the bald – but very red-faced – uakari, all populate the region. Effectively, it forms part of a vast “ecological corridor” running all the way from the Madidi National Park in Bolivia in a north-westerly direction along much of the Peru-Brazil border.

21 indigenous communities and 42 other settlements would benefit from the Sierra del Divisor being properly protected, states the Environment Ministry, while ultimately over 230,000 people in Peru depend on the region for food and water, according to the IBC. In addition, in the absolute remotest parts, it is home to various groups of indigenous peoples living in what Peruvian law calls “isolation.”

In 2006 Peru’s government established a 1.4 million hectare temporary “protected natural area” in this region called the Sierra del Divisor Reserved Zone. Six years later a government commission agreed it would be converted into a national park, and, all that remains now, after a painful administrative process, several key advances made this year and indigenous leaders lobbying various ministries, is for Peru’s Cabinet to approve it and the president, Ollanta Humala, to sign off on it. That is how it has stood since early May 2015 – and still nothing….

Why such a delay indeed, this year or in the past? Might it have something to do with the infrastructure integration plans for the region, such as the proposed – and effectively already underway – road between Pucallpa, the Peruvian Amazon’s current boom city, and Cruzeiro do Sul across the border in Brazil? Or the proposed railway between the same two cities ultimately connecting to Peru’s northern Pacific coast, declared in the “national interest” some years ago? Or the proposed railway running all the way across South America from Peru’s Pacific coast to Brazil’s Atlantic coast, a long-mooted project which has received so much media coverage recently because of Chinese interest in financing it and the visit by China’s premier, Li Keqiang, to Brazil and Peru in May?

Or might the delay be explained by oil and gas industry interests? Perupetro, the state company promoting oil and gas operations, tried to open up what would be the entire southern part of the park for exploration before backtracking in 2008, while the London Stock Exchange-Alternative Investment Market-listed company Maple Energy has been pumping oil for years in a concession just overlapping the west of the proposed park. More significantly, Canadian-headquartered company Pacific Rubiales Energy runs a one million hectare oil concession that would overlap the entire northern part of the park if it was established, and conducted its first phase of exploratory drilling and seismic tests in late 2012 and 2013 in what would be the park’s far north. Clearly, it wouldn’t be good PR for either Pacific or Peru to explore for oil in, or exploit oil from, a national park, although it wouldn’t be the first time a concession and park have overlapped. Indeed, according to the IBC, it has been agreed that Pacific’s “rights” to operate will be respected if the park is created.

Biofuels Revolution? not really

B]iofuel schemes—ranging from fermenting starch, to recycling cooking oil, to turning algae into jet fuel—have drawn more than $126 billion in investment since 2003, according to Bloomberg New Energy Finance (BNEF), a research outfit… [But]Those biofuels that can best compete commercially are not, in fact, green. Those that are green cannot compete commercially.

The biggest cause of ungreenness is that biofuels made from food crops—or from plants grown on land that might otherwise produce such crops—hurt food supplies. A committee of the European Parliament agreed this week to cap the use of “first-generation” biofuels of this sort. The current European target is for renewables to make up 10% of the energy used in transport by 2020. The new proposal says only seven-tenths of this can come from first-generation fuels. The difference must be made up by more advanced ones based on waste products and other feedstocks that do not impinge on food production. That could mean European demand for advanced biofuels of 14 billion litres by 2020, reckons Claire Curry of BNEF.
Only two such advanced fuels, she thinks, are capable of large-scale production. One is turning waste cooking oil and other fats into diesel—a process for which Europe already has 2 billion litres of capacity. The other involves making ethanol from cellulose by enzymatic hydrolysis. Everything elseis at least four years from commercial production. That includes the much-touted idea of renewable jet fuel.  This is promising on a small scale. South African Airways (SAA), in conjunction with Boeing and other partners, is developing fuel based on the seeds of the tobacco plant—once a big crop in the country, but now fallen on hard times.

Right to Water and Indigenous People: New Zealand

The Maori claim a special relationship with New Zealand’s fresh water, based on their historical use of its rivers for drinking water, spiritual beliefs, fishing and shellfish harvest, transport and trade, among other things. Their case goes back to 1840, when the British Crown and most of the Maori tribes signed the Waitangi treaty, which first formalised the colonists’ settling of the islands. Maori rights were enshrined in the treaty. An interim ruling by the Waitangi tribunal, set up in 1975 to deal with Maori grievances about land and related issues, says that the Maori have freshwater rights “for which full ownership was the closest cultural equivalent in 1840.”

Although the government has been willing to discuss water rights with some Maori groups, John Key, the prime minister, says that “full ownership” will not be ceded. In 2012 the government sought to part-privatise Mighty River Power, an electricity company with dams on the longest river, the Waikato, which has particular spiritual value for the Tainui tribe. The Maori Council, with representatives from each Maori district, tried to have the sale stopped or postponed. But in 2013 the high court ruled in the government’s favour….

One proposal is that the Maori get a specified water allocation from regional councils, just as farms do. But Federated Farmers, a lobby group, argues that all available water has already been allocated and that specifying a share for the Maori would mean others losing out. New Zealand’s farms rely heavily on water—especially in the dairy sector, which is now the country’s biggest export earner, worth $10 billion a year.

Growing Chinese demand for milk powder means farmers are increasingly switching from meat production to dairy, thereby increasing their water use. Dairy farming is also polluting freshwater supplies, as phosphates and nitrates seep into groundwater. This has become a political issue, not just for the Maori: many of the rivers and lakes loved by all Kiwis are no longer safe to swim in. The most likely outcome is a fudge that avoids saying anyone owns New Zealand’s fresh water. But the Maori may get more influence over some water, or even an allocation.

Building Climate Resilience in Ecosystems

Some ecosystems show little response [to climate change] until a threshold or tipping point is reached where even a small perturbation may trigger collapse into a state from which  recovery is difficult .  ….[S}uch collapse may be altered by conditions that can be managed locally…. [This] provides  potential opportunities for pro-active management.…[C]rises in iconic UNESCO World Heritage sites illustrate that such stewardship is at risk of failing. The term “safe operating space” frames the  problem of managing our planet in terms of staying within acceptable levels or “boundaries” for global stressors [Such as climate change]….

Obviously, local interventions are no panacea for the threats of climatic change. For example, melting of arctic sea ice with its far-reaching ecological consequences cannot be arrested by local management. However, ways of building climate resilience are emerging for a variety of ecosystems, ranging from control of local sources of ocean acidification  to management of grazing pressure on dry ecosystems,World Heritage Areas.

The Doñana wetlands in southern Spain provide the most important wintering site for waterfowl in Europe. They contain the largest temporary pond complex in Europe, with a diversity of amphibians and invertebrates. Despite the site’s protected status, the marshes are threatened by eutrophication due to pollution and reduced flow of incoming streams, promoting toxic cyanobacterial blooms and dominance by invasive floating plants that create anoxic conditions in the water. In addition, groundwater extraction for strawberry culture and beach tourism also has major impacts.  Little has been done to control these local stressors, leaving Doñana unnecessarily vulnerable to climate change. UNESCO has just rated this World Heritage Site as under ‘very high threat’.

The Great Barrier Reef is the largest coral system in the world. In response to multiple threats, fishing has been prohibited since 2004 over 33% of the Great Barrier Reef Marine Park, and efforts have begun to reduce runoff of nutrients, pesticides, herbicides and sediments from land. However, these interventions may be too little, too late. Approximately half of the coral cover has been lost in recent decades, and the outlook is “poor, and declining” with climate change, coastal development and dredging as major future threats. The World Heritage Committee has warned that in the absence of a solid long-term plan, it would consider listing the reef as “in danger” in 2015.

Green Dams that Kill

A planned mega-dam in Guatemala, whose carbon credits will be tradable under the EU’s emissions trading system, has been linked to grave human rights abuses, including the killing of six indigenous people, two of them children.  Several European development banks and the World Bank’s International Finance Corporation (IFC) have provided funds for the $250m (£170m) Santa Rita dam.

But human rights groups back claims from the Mayan community that they were never consulted about the hydro project, which will forcibly displace thousands of people to generate 25MW of energy, mostly for export to neighbouring countries.  The issue has become a focus of indigenous protest in Guatemala – which has led to a march on the capital and severe political repression.

“At the moment our community is living under the same conditions as they did during the war,” Maximo Ba Tiul, a spokesman for the Peoples’ Council of Tezulutlán told the Guardian. “Our civilian population is once again being terrorised by armed thugs.”  Around 200,000 Mayans died or were “disappeared” during the civil war of the early 1980s, leading to the conviction of the country’s former president, Efraín Ríos Montt, in 2013 on genocide charges.

Augusto Sandino Ponce, the son of a local landowner who community leaders allege worked as a contractor to Montt’s junta during the civil war, is at the centre of new accusations of human rights violations. Last April Ponce and his bodyguards allegedly opened fire on a Mayan community ceremony in which families asked the Earth for permission to plant their crops. One local man, Victor Juc, was killed and several were injured. Ponce reportedly claims he was acting in self defence…

In a letter to the United Nations Framework Convention on Climate Change’s (UNFCCC) clean development mechanism (CDM) executive board,  the People’s Council of Tezulutlán outlined a litany of human rights abuses in the region, including kidnappings, evictions, house burnings, attacks by men wielding machetes and guns, and the arrest of community leaders.  The council also says that an environmental impact assessment for the dam suggests that it would create a 40ft-high wall, flooding local communities and depriving them of access to water, food, transport and recreation.  In approving projects, the CDM board pursues a narrow remit focused on emissions reductions. The reign of terror in the Alta Verapaz region, falls outside it – as did similar events in Honduras….

Perhaps the most shocking incident took place on 23 August 2013, when two children were killed by an allegedly drunken Santa Rita hydroelectricity company worker looking for David Chen, a community leader in the Monte Olivo region.   Chen was meeting with the rapporteur of the Inter American Commission on Human Rights at the time. When the worker could not find him, he is said to have lined up two of Chen’s nephews, David Stuart Pacay Maaz, 11 and Haggai Isaac Guitz Maaz, 13, and killed them with a single bullet to one child’s head that continued through the throat of the other. The killer has since been killed himself.  The annual report of the UN’s High Commissioner for Human Rights implicitly blamed the approval of the dam project for the killings….

Eva Filzmoser, the director of Carbon Market Watch said: “We want the CDM board to take responsibility and establish a grievance and redress mechanism for local communities to appeal, ask for problematic decisions to be rescinded and gain redress. We will be pushing for this at the Paris climate summit to apply to all forms of climate finance in the future.”Efforts to reform the CDM were boosted last month, when 18 countries signed a “Geneva declaration” calling for human rights norms to be integrated into UNFCCC climate decisions….Signatory countries to the declaration include France, Sweden, Ireland, Mexico, Uruguay and Peru.

Costs of Dams: Vietnam

Hydropower has boomed in Vietnam over the past decade and now generates more than a third of the country’s electricity. In 2013 the National Assembly reported that 268 hydropower projects were up and running, with a further 205 projects expected to be generating by 2017. They are helping to meet a national demand for energy that the authorities forecast will treble between 2010 and 2020. Other power sources are less promising, at least in the short run. A plan to build several nuclear reactors by 2030 is behind schedule, for example. And Vietnam’s coal reserves, mostly in the north, are not easy to get at.

Yet the hydropower boom comes at a price. Rivers and old-growth forests have been ravaged, and tens of thousands of villagers, often from ethnic minorities, displaced. Many have been resettled on poor ground. Those who have stayed are at risk of flash floods caused by faulty dam technology and inadequate oversight. Green Innovation and Development Centre, an environmental group in the capital, Hanoi, says shoddy dam construction is the norm, and developers ignore the question of whether their projects could trigger earthquakes…

Many hydro-electric companies are owned by or affiliated with Electricity Vietnam (EVN), the loss-making state power monopoly. Because hydropower is Vietnam’s cheapest source of electricity, EVN resists investing in measures such as dam-safety assessments that would further erode its financial position. As it is, even though environmental-impact assessments for hydropower projects are required, they are never published, according to the United Nations Development Programme….. Hydropower companies want to keep their mountain reservoirs as full as possible in order to generate as much electricity as Vietnam’s rivers allow. But that narrow focus can deprive farmers of irrigation in the dry season. And when heavy rains come in the summer and autumn, floodwaters cascade over the dam walls with little or no warning.

Deforestation: mixed picture

In a new study of the Centre for Global Development (CGD), a Washington think-tank, Jonah Busch and Kalifi Ferretti-Gallon look at 117 cases of deforestation round the world. They find that two of the influences most closely correlated with the loss of forests are population and proximity to cities (the third is proximity to roads). Dramatic falls in fertility in Brazil, China and other well-forested nations therefore help explain why (after a lag) deforestation is slowing, too. Demography even helps account for what is happening in Congo, where fertility is high. Its people are flocking to cities, notably Kinshasa, with the result that the population in more distant, forested areas is thinning out.

Two of the countries that have done most to slow forest decline also have impressive agricultural records: Brazil, which became the biggest food exporter of all tropical countries over the past 20 years; and India, home of the green revolution. Brazil’s agricultural boom took place in the cerrado, the savannah-like region south and east of the Amazon (there is farming in the Amazon, too, but little by comparison). The green revolution took place mostly in India’s north-west and south, whereas its biggest forests are in the east and north.

But if population and agricultural prowess were the whole story, Indonesia, where fertility has fallen and farm output risen, would not be one of the worst failures. Figures published inNature Climate Change in June show that in the past decade it destroyed around 60,000 sq km of primary forests; its deforestation rate overtook Brazil’s in 2011. Policies matter, too—and the political will to implement them.

The central problem facing policymakers is that trees are usually worth more dead than alive; that is, land is worth more as pasture or cropland than as virgin forest. The benefits from forests, such as capturing carbon emissions, cleaning up water supplies and embodying biodiversity, are hard to price….The most successful policies therefore tend to be top-down bans, rather than incentives (though these have been tried, too). India’s national forest policy of 1988 explicitly rejects the idea of trying to make money from stewardship. “The derivation of direct economic benefit”, it says, “must be subordinated to this principal aim” (maintaining the health of the forest). In Brazil 44% of the Amazon is now national park, wildlife reserve or indigenous reserve, where farming is banned; much of that area was added recently. In Costa Rica half the forests are similarly protected. In India a third are managed jointly by local groups and state governments.

Top-down bans require more than just writing a law. Brazil’s regime developed over 15 years and involved tightening up its code on economic activity in forested areas, moratoriums on sales of food grown on cleared land, a new land registry, withholding government-subsidised credit from areas with the worst deforestation and strengthening law enforcement through the public prosecutor’s office. (The most draconian restriction, requiring 80% of any farm in the Amazon to be set aside as a wildlife reserve, is rarely enforced.)

Two developments make bans easier to impose. Cheaper, more detailed satellite imagery shows in real time where the violations are and who may be responsible. Brazil put the data from its system online, enabling green activists to help police the frontier between forest and farmland. Its moratoriums on soyabeans and beef from the Amazon, which require tracing where food is coming from, would not have worked without satellites…

The Forestry Ministry of Indonesia, [on the other hand] is rated the most corrupt among 20 government institutions by Indonesia’s Corruption Eradication Commission in 2012. Some within government are hostile to anti-deforestation schemes, which they see as “foreign”, says Ade Wahyudi of Katadata, an Indonesian firm of analysts. Perhaps the biggest problem is the lack of a single, unified map including all information on land tenure and forest licensing: efforts to create one have been slowed by unco-operative government ministries and difficulties created by overlapping land claims.

Weather Modification in India

State governments, tea estate owners, politicians and even some insurance companies are exploring cloud-seeding options. The process involves seeding clouds with chemicals that will lead them to promote precipitation or rain. (The process is also used to boost snowfall and curb hailstones and fog.)  [Indian] companies involved in cloud seeding such as Myavani, Kyathi Climate Modification Consultants [affiliated  with US based Weather Modification Inc.]and Agni Aero Sports expect business to grow as much as a fourth this year over 2012, when the country last saw weak rains.

Bangalore-based Agni Aero Academy, which has been involved in cloud seeding in India since 2003 and undertook cloud-seeding projects for MCGM [Municipal Corporation of Greater Mumbai]  in 2009 and the Karnataka government in 2012, expects a pickup in business.

Girish Odugoudar, 33, of Myavani, which has jointly bid for the Mumbai project along with US National Centre for Atmospheric Research, is aiming to establish his business. “We have the infrastructure and capability and success in one project should open many doors,” he said.

On-Demand Germs: Bioengineering for the Military

From the DARPA website:

The development of increasingly sophisticated techniques and tools to sequence, synthesize and manipulate genetic material has led to the rapidly maturing discipline of synthetic biology. …[But] The costs of maintaining required environmental controls and detecting and compensating for genetic alterations are substantial and severely limit the widespread application of synthetic biology to U.S. national security missions.

To help address these challenges, DARPA has created the Biological Robustness in Complex Settings (BRICS)  BRICS seeks to develop the fundamental understanding and component technologies needed to increase the biological robustness and stability of engineered organisms while maintaining or enhancing the safe application of those organisms in complex biological environments. The goal is to create the technical foundation for future engineered biological systems to achieve greater biomedical, industrial and strategic potential.

“By making these systems more robust, stable and safe, BRICS seeks to harness the full range of capabilities at the intersection of engineering and biology,” said Justin Gallivan, DARPA program manager. “These capabilities could include efficient on-demand bio-production of novel drugs, fuels, sensors and coatings; or engineered microbes able to optimize human health by treating or preventing disease.”
