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.

The Forced Migration of Endangered Species

Rhino translocations have become a critical tool in the arsenal for the protection of these endangered animals. Recently, 30 white rhinos were flown into Rwanda from South Africa and introduced into the Akagera National Park, in what is the single largest translocation. 

In the late 19th century, southern white rhinos were almost on the brink of extinction. This was due to poaching and hunting. But in 1895 a small population of fewer than 100 individuals was discovered in KwaZulu-Natal, South Africa. After more than a century of protection and good management, there are now around 17,600 white rhinos (as of 2018) living in protected areas and private game reserves…However, this success story is being threatened by the illegal trade in horn. Between 2006 and 2020, 10,600 rhinos across the continent have been lost. With the exception of a few areas, rhinos are surviving in well protected, smaller national parks and reserves.

Why were rhinos translocated to Rwanda? Having a population in a Rwanda could create a secure new breeding stronghold in East Africa and help ensure the long-term survival of the species in the wild…

Any international translocation requires political support from national governments and conservation authorities and should be in full compliance with international agreements, such as CITES…Sourcing the animals is also an important aspect… South Africa has a vibrant wildlife industry based upon the buying and selling of wildlife. 

Catching and Translocating the Animals: A lot of time is spent on planning for this and ensuring the animals are treated as well as possible. Moving animals over thousands of kilometers is a serious endeavor. With 30 animals, chartered jumbo jets are the best way. This requires considerable veterinary and logistical coordination to capture the animals, load into crates, transport to the aircraft, load as quickly as possible, unload similarly, transport to the site and release into well-sited and secure bomas. 

Upon arrival, animals are put into holding bomas to get them adjusted to the local different foods that they’ll encounter…Once they’re in the new habitat, the next concern is security and making sure people can take care of them and monitor them.

Global Microbiome Living on Plastics

The number of microbial enzymes with the ability to degrade plastic is growing, in correlation with local levels of plastic pollution. That is the finding of a study from Chalmers University of Technology, Sweden, that measured samples of environmental DNA from around the globe. The results illustrate the impact plastic pollution is having on the environment, and hint at potential new solutions for managing the problem.

The study analyzed samples of environmental DNA from hundreds of locations around the world. The researchers used computer modelling to search for microbial enzymes with plastic-degrading potential, which was then cross-referenced with the official numbers for plastic waste pollution across countries and oceans. “Using our models, we found multiple lines of evidence supporting the fact that the global microbiome’s plastic-degrading potential correlates strongly with measurements of environmental plastic pollution – a significant demonstration of how the environment is responding to the pressures we are placing on it,” says Aleksej Zelezniak, Associate Professor in Systems Biology at Chalmers University of Technology. 

More enzymes in the most polluted areas: In other words, the quantity and diversity of plastic-degrading enzymes is increasing, in direct response to local levels of plastic pollution. In total, over 30,000 enzyme ‘homologues’ were found with the potential to degrade 10 different types of commonly used plastic. Homologues are members of protein sequences sharing similar properties. Some of the locations that contained the highest amounts were notoriously highly polluted areas, for example samples from the Mediterranean Sea and South Pacific Ocean…

The researchers believe that their results could potentially be used to discover and adapt enzymes for novel recycling processes…“The next step would be to test the most promising enzyme candidates in the lab to closely investigate their properties and the rate of plastic degradation they can achieve. From there you could engineer microbial communities with targeted degrading functions for specific polymer types,” explains Aleksej Zelezniak.

Detoxing the Fish of Our Lakes and Rivers

Fish populations appear to recover rapidly from mercury pollution once humans stop adding it to their environment. A 15-year study of a lake in Canada found that eight years after the metal’s supply ceased, concentrations of methylmercury – a highly toxic substance made from mercury by bacteria in aquatic ecosystems – fell by 76 per cent… 

“I can’t imagine a much faster recovery,” says Paul Blanchfield at government agency Fisheries and Oceans Canada, who led the research. The team are not suggesting the fish excrete the mercury quickly – the experiment in fact shows they hang on to it for a long time – but that quick turnover of generations sees concentrations fall fast when new pollution stops.

Mercury pollution is still a major global environmental problem, with small-scale gold mining and coal burning being the two biggest sources. Transported in the atmosphere and rained down on lakes and oceans, the metal’s accumulation in freshwater and marine species has raised concerns over the human health impact of eating fish.

To Save the Congo Rainforest, We Must Save the People First

The Special Representative of the Secretary-General in the Democratic Republic of the Congo told the Security Council in December 2021  that “a lasting solution” to the violence” in Congo requires a broader political commitment to address the root causes of conflict.”  Bintou Keita argued that, for stability to return to eastern Congo, “the State must succeed in restoring and maintaining the confidence of the people in state’s ability to protect, administer, deliver justice and meet their basic needs.” 

Starting on November 30, 2021  the Congolese Armed Forces initiated joint military operations with the Ugandan army against the rebel Allied Democratic Forces (ADF) in the east.  In May 2021, the Congolese authorities declared a state of siege in the provinces of Ituri and North Kivu, whose duration has just been extended for the 13th time

But the challenges facing the Government in implementing the state of siege highlight “the limits of a strictly military approach to the protection of civilians and the neutralization of armed groups.”  In fact, the period of the state of siege saw a 10 per cent increase in the number of violations and abuses of human rights in the country.  


According to the Special Representative, the humanitarian situation continues to deteriorate in the restive east, due to insecurity, epidemics, and limited access to basic services.  The number of internally displaced people stands at nearly 6 million, of which 51 per cent are women. This is the highest number of internally displaced people in Africa.  

The Special Representative pointed out the illegal exploitation of natural resources as “a major driver of conflict”, saying it must be addressed, and commended President Tshisekedi’s intervention at the COP26 Summit, where he committed to combat deforestation in the Congo Basin rainforest and reduce greenhouse gas emissions by 21 per cent, by 2030….

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.

What’s in that Suitcase? Endangered Turtles

Live animals, python skins and slimming pills made from crocodile blood are just a few of the items seized at world borders recently. In the space of a month, 29 big cats, 531 turtles, 336 reptiles, 1.4 million plant-derived products and 75,320kg of timber were found in luggage. 300 arrests were made. Many of the items are part of the world’s fourth biggest illegal market – the illegal wildlife trade. Despite decades of lawmakers’ crackdowns, it is still worth an estimated €17 billion annually.

The smuggled items were found as part of Operation Thunder 2021, which spanned 118 countries and the work of customs, police and wildlife enforcement agencies. The operation, coordinated by the World Customs Organisation (WCO) and INTERPOL, involved searching cars, boats and lorries with sniffer dogs and X-ray scanners. Law enforcement found that online platforms are being used to arrange trafficking, and illegal money transfers are used to enable money laundering.

Why Crabs and Mussels Love Plastic Pollution

The “Great Pacific Garbage Patch,” is considered the world’s largest accumulation of ocean plastic. It’s so massive, in fact, that researchers found it has been colonized by species — hundreds of miles away from their natural home. The research, published in the journal Nature, found that species usually confined to coastal areas — including crabs, mussels and barnacles — have latched onto, and unexpectedly survived on, massive patches of ocean plastic.  As suitable habitat made of plastics now exists in the open ocean, coastal organisms can both survive at sea for years and reproduce, leading to self-sustaining coastal communities on the high seas!

But the mingling of the neuston and coastal species is “likely recent,” researchers said, and was caused largely because of the accumulation of “long-lived plastic rafts” that have been growing since the middle of the 20th century. Just by itself, the Great Pacific Garbage Patch, located between California and Hawai’i, is estimated to have at least 79,000 tons of plastic within a 1.6 million-square-kilometer area. There are at least four other similar patches throughout the world’s oceans. Researchers expect that plastic waste is going to “exponentially increase,” and by 2050, there will be 25,000 million metric tons of plastic waste.  

For lead author Linsey Haram, the research shows that physical harm to larger marine species should not be the only concern when it comes to pollution and plastic waste. “The issues of plastic go beyond just ingestion and entanglement,” Haram said in a statement. “It’s creating opportunities for coastal species’ biogeography to greatly expand beyond what we previously thought was possible.” 

But that expansion could come at a cost. “Coastal species are directly competing with these oceanic rafters,” Haram said. “They’re competing for space. They’re competing for resources. And those interactions are very poorly understood.” There is also a possibility that expansions of these plastic communities could cause problems with invasive species. A lot of plastic found in the Great Pacific Garbage Patch, for example, is debris from the 2011 Tohoku tsunami in Japan, which carried organisms from Japan to North America. Over time, researchers believe, these communities could act as reservoirs that will provide opportunities for coastal species to invade new ecosystems. 

There are still many questions researchers say need to be answered about these new plastic-living communities — like how common they are and if they can exist outside the Great Pacific Garbage Patch — but the discovery could change ocean ecosystems on a global scale, especially as climate change exacerbates the situation.

The Limits of Green Energy: Wind Blades of Wood and Plastic

What does the deforestation of balsa wood in Ecuador’s Amazon region have to do with wind power generation in Europe? There is a perverse link between the two: a drive for renewable energy has boosted global demand for a prized species of wood that grows in the world’s largest rainforest. As Europe and China increase the construction of blades for wind turbines, balsa trees are being felled to accelerate an energy transition driven by the need to decarbonize the global economy.

In the indigenous territories of the Ecuadorian Amazon, people began to notice an uptick in international demand for balsa wood from 2018 onwards. Balsa is very flexible but tough at the same time, and offers a light yet durable option for long-term wind power production. The typical blades of a wind turbine are currently around 80 meters long, and the new generation of blades can extend up to 100 meters. That means about 150 cubic meters of wood are required to build a single unit, according to calculations by the United States National Renewable Energy Laboratory.

Ecuador is the world’s main exporter of balsa wood, holding 75% of the global market. Major players include Plantabal S.A. in Guayaquil, which has around 10,000 hectares dedicated to the cultivation of balsa wood destined for export. With the boom in demand starting in 2018, this company and many others struggled to cope with the quantity of international orders. This increase has led directly to the deforestation of the Amazon. Irregular and illegal logging has proliferated by those who have reacted to the scarcity of wood grown for timber by chopping down the virgin balsa that grows on the islands and riverbanks of the Amazon

The impact on the indigenous people who live in the area has been as devastating as mining, oil and rubber were in their day…The Amazon’s defenders are calling for the wind turbine industry to implement strict measures to determine the origin of the wood used in turbine blades, and to prevent market pressure leading to deforestation. Ultimately, they say, balsa wood should be replaced by other materials…

In 2019, Ecuador’s balsa exports were worth almost €195 million, 30% more than the previous record from 2015. In the first 11 months of 2020, this jumped to €696 million.

Wind turbine blades are mainly made from polymethacrylamide (PMI) foam, balsa wood and polyethylene terephthalate (PET) foam…But The Spanish-German company Siemens-Gamesa..has  introduced blade designs using PET only, other competitors soon followed. Wood Mackenzie, a consultancy firm, forecasts that this “will increase from 20% in 2018 to more than 55% in 2023, while demand for balsa will remain stable…”

Today’s blades also present a problem for recycling. The first generation of wind turbines are reaching the end of their lives, and thousands will need to be dismantled… “But the blades represent a challenge due to their composite materials, as their recycling requires very specific processes…

Exchanging Nature for Crushing Debt

In 2020 tourism in Belized dried up, growth contracted sharply and public debt jumped from just under 100% GDO in 2019 to over 125%. That forced Belize,  into a debt restructuring…As part of the deal, concluded on November 5th, 2021 Belize bought back its only international bond, a $553m, at 55 cents on the dollar. It funded that with $364m of fresh money, arranged by The Nature Conservancy, an NGO, which is insured by the International Development Finance Corp, an American agency. The transaction is backed by the proceeds of a “blue bond” arranged by Credit Suisse, a bank. The payback is due over 19 years. It is called a blue bond because Belize has pledged to invest a large chunk of the savings into looking after the ocean. That includes funding a $23m endowment to support future marine-conservation projects and promising to protect 30% of its waters by 2026…

Debt-for-nature swaps are nothing new. Lenders have been offering highly indebted countries concessions in return for environmental commitments for decades. But these transactions have historically involved debt owed to rich countries, not commercial bondholders. As Lee Buchheit, a lawyer who specialises in sovereign-debt restructurings, points out, they were “negligible in size”. In total, the value of debt-for-climate and nature-swap agreements between 1985 and 2015 came to just $2.6bn, according to the United Nations Development Programme. Of the 39 debtor nations that benefited from the swaps, only 12 negotiated debts of over $30m. “It was really an exercise in public relations,” Mr Buchheit says….

Other poor countries are trying to move in the same direction. At the COP26 climate summit in Glasgow Ecuador’s president Guillermo Lasso proposed enlarging the country’s Galapagos nature reserve through a debt-for-nature swap…Yet no amount of creative dealmaking can distract from the grim truth: many emerging markets still suffer from crushing debts.

Animal Rights March On

A dispute over the fate of hippos in Colombia has given rise to a federal court ruling in Ohio, United States that, for the first time in American law, recognizes animals as people. This should come as welcome news to the 100-plus hippos of Colombia’s Magdalena river. They are the offspring of four hippos smuggled into the country by Pablo Escobar, a drug lord. 

The surfeit of hippos has coated lakes with algae and could displace otters, manatees and endangered turtles. Hippos have begun wandering into villages, too—a potential peril for human persons. In 2020, Colombia’s government considered a cull, prompting a Colombian lawyer to take up the cause. The hippos, his lawsuit says, enjoy protection under Colombian law and must not be killed….

Judge Karen Litkovitz, the federal judge in Ohio (USA), does not get to decide the hippos’ fate. But on October 15, 2021 she agreed with the Animal Legal Defense Fund that the hippos are “interested persons” under a law permitting foreign litigants to gather evidence in America that may buttress their claims. Experts in non-surgical sterilization will be deposed for their insights on PZP, a contraceptive that could spare the hippos while dampening their growth.

America is not the first country to regard animals as legal persons. An Indian court cited the constitution in banning a bullfighting festival in 2014. A judge in Argentina ruled that Sandra, an orangutan, was a non-human person eligible for better environs than her concrete enclosure in a Buenos Aires zoo; she now luxuriates in a sanctuary in Florida. In 2020 a court in Islamabad, faced with cases involving stray dogs, an elephant and a bear, recognized the “right of each animal…to live in an environment that meets the latter’s behavioral, social and physiological needs”.

Judge Litkovitz’s decision is not couched in such sweeping terms. It remains to be seen whether other American courts take her cue in cases such as that of Happy, an elephant at the Bronx Zoo who has shown signs of self-awareness and misery. In 2022 New York’s highest court will consider whether the writ of habeas corpus—protection from unjust imprisonment—applies to Happy.

A Breach Too Far: 413 PPM

The abundance of heat-trapping greenhouse gases in the atmosphere once again reached a new record in 2021, with the annual rate of increase above the 2011-2020 average. That trend has continued in 2021, according to the World Meteorological Organization (WMO) Greenhouse Gas Bulletin.

Concentration of carbon dioxide (CO2), the most important greenhouse gas, reached 413.2 parts per million in 2020 and is 149% of the pre-industrial level. Methane (CH4) is 262% and nitrous oxide (N2O)  is 123% of the levels in 1750 when human activities started disrupting Earth’s natural equilibrium.

Roughly half of the CO2 emitted by human activities today remains in the atmosphere. The other half is taken up by oceans and land ecosystems. The Bulletin flagged concern that the ability of land ecosystems and oceans to act as “sinks” may become less effective in future, thus reducing their ability to absorb carbon dioxide and act as a buffer against larger temperature increase…Such changes are already happening, for example, transition of the part of Amazonia from a carbon sink to a carbon source

The Bulletin shows that from 1990 to 2020, radiative forcing – the warming effect on our climate – by long-lived greenhouse gases increased by 47%, with CO2 accounting for about 80% of this increase…The amount of CO2 in the atmosphere breached the milestone of 400 parts per million in 2015. And just five years later, it exceeded 413 ppm. 

“Carbon dioxide remains in the atmosphere for centuries and in the ocean for even longer. The last time the Earth experienced a comparable concentration of CO2 was 3-5 million years ago, when the temperature was 2-3°C warmer and sea level was 10-20 meters higher than now. But there weren’t 7.8 billion people then,” said Prof. Taalas.

Repairing Damaged Coral Reefs

Rather than blocking waves, as a sea wall does, a reef slows them, dissipating their energy before they reach land. One estimate, from the University of California, Santa Cruz and the Pacific Coastal and Marine Science Centre, suggests natural reefs prevent $1.8bn a year of flood damage in America alone.

While natural reefs take centuries to grow, hybrid versions can be conjured up in months. The idea began with Wolf Hilbertz, an architect with an interest in marine biology. In the 1970s Hilbertz developed a technique that uses submerged electrodes to run electrical currents through seawater. This precipitates calcium carbonate and magnesium hydroxide out of the seawater, forming limestone similar to that of natural reefs. The artificial reef can become the substrate upon which a natural coral ecosystem develops…Later work with Thomas Goreau, a marine biologist, produced both a catchy name—“Biorock”—and the idea of using the stuff as the basis of coral reefs, and, in particular, for repairing damaged reefs.

In 1996 the Global Coral Reef Alliance, a charity, began using Biorock for reef repairs by growing a six-metre structure in the Maldives. Other repairs have followed in Indonesia, Jamaica and Mexico. The Pemuteran Coral Reef Restoration Project, in Bali, is more than 300 metres long and includes dozens of “nurseries” in which Biorock acts as nuclei for the natural extension of the reef….DARPA a research agency run by America’s Department of Defense, also sees hybrid reefs as a means of coastal defence—in this case protecting the country’s seaside military installations. Lori Adornato, head of DARPA’s “Reefense” project, says the goal is a hybrid reef-type system which will be maintenance-free and self-repairing. Reefense therefore involves not only creating reefs and measuring their effectiveness, but also attracting and fostering appropriate organisms to sustain the reefs’ health, ensuring they can survive even when natural reefs are suffering.

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.

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.

Who Owns your Cells? the case of Henrietta Lacks

In 1951, a young mother of five named Henrietta Lacks visited The Johns Hopkins Hospital complaining of vaginal bleeding….As medical records show, Mrs. Lacks began undergoing radium treatments for her cervical cancer…. A sample of her cancer cells retrieved during a biopsy were sent, without her knowledge or consent, to Dr. George Gey’s nearby tissue lab. For years, Dr. Gey, a prominent cancer and virus researcher, had been collecting cells from all patients who came to The Johns Hopkins Hospital with cervical cancer, but each sample quickly died in Dr. Gey’s lab. What he would soon discover was that Mrs. Lacks’ cells were unlike any of the others he had ever seen: where other cells would die, Mrs. Lacks’ cells doubled every 20 to 24 hours.

Today, these incredible cells— nicknamed “HeLa” cells, from the first two letters of her first and last names — are used to study the effects of toxins, drugs, hormones and viruses on the growth of cancer cells without experimenting on humans. They have been used to test the effects of radiation and poisons, to study the human genome, to learn more about how viruses work, and played a crucial role in the development of the polio vaccine.

In July 2021, the family of Henrietta Lacks has hired a prominent civil rights attorney, who says he plans to seek compensation for them from big pharmaceutical companies across the country that made fortunes off medical research with her famous cancer cells…The legal team is investigating lawsuits against as many as 100 defendants, mostly pharmaceutical companies, but they haven’t ruled out a case against the Johns Hopkins Hospital.’

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.

The Leaky Oil Pipelines on Our Seafloor

Federal officials aren’t adequately monitoring the integrity of 8,600 miles of active oil-and-gas pipelines on the Gulf of Mexico’s seafloor, and for decades have allowed the industry to abandon old pipelines with little oversight, a new report to Congress shows. The Government Accountability Office report faults the Interior Department’s offshore oil-safety regulator’s reliance on surface observations and pressure sensors, rather than  subsea inspection, to monitor for leaks.

The report urges the regulator, the Bureau of Safety and Environmental Enforcement (BSEE), to resume work on a long-stalled update to pipeline rules. BSEE currently requires monthly inspections of pipeline routes in the Gulf by helicopter or marine vessel, to look for oil sheens or gas bubbles on the surface to determine whether a pipeline is leaking. By comparison, the bureau’s Pacific office requires subsea pipeline inspections, in part because of seismic concerns, on its much smaller network of 200 miles of active pipelines.

The GAO also found that BSEE and its predecessors allowed the oil industry to leave thousands of miles of decommissioned pipelines on the seafloor rather than incur the cost of raising them back to the surface. Federal regulations allow BSEE to permit operators to decommission pipelines in place, cleaning and burying them in the seabed. The GAO found that the agency doesn’t ensure standards are followed, even as it allowed 97% of the miles of decommissioned pipelines taken out of active use in the Gulf since the 1960s—nearly 18,000 miles—to remain in place.

BSEE also has failed to fully consider whether decommissioned pipelines represent a hazard to navigation and commercial fishing, like trawlers that can be damaged by snagging equipment on undersea pipelines, the report said. Eighty-nine trawlers reported damage from snagging on oil-and-gas equipment between 2015 and 2019, the report found.

BSEE’s failure to inspect decommissioned pipelines also means officials don’t have a complete record of which equipment has been properly cleaned and buried, or whether hurricanes and underwater landslides have moved buried pipelines, potentially creating navigation hazards and environmental damage. A buried 9-mile pipeline segment was swept 4,000 feet out of place by Hurricane Katrina, the report said.

BSEE also allowed oil producers to leave in place some 250 decommissioned “umbilical lines” that carry electricity and hydraulic power to subsea equipment, the report said, over objections of some Interior officials who were concerned that these lines often contain hazardous chemicals that could leak over time as the equipment degrades.

The Plastics Revolution: A Century Later

Businesses pay a fee to Tontoton,  a company established in 2019,  for every ton of plastic that they generate. Tontoton then uses the money to employ scavengers, who retrieve an equal weight of plastic garbage in Vietnam — the world’s No. 4 source of ocean debris…Tontoton said it has the only such program in Vietnam, while Plastic Bank runs a similar one in Indonesia and the Philippines, and the Plastic Collective covers Malaysia, Thailand, and Cambodia…Tontoton targets the worst ocean-bound rubbish, called orphan plastic because it cannot be recycled. Trash pickers find the single-use plastic along the cyan waters hugging Vietnam’s Phu Quoc and Hon Son islands. Their goal is to collect 5,000 tons a year and send it to INSEE, part of Siam City Cement, to be burned for energy….

These cleanup programs have sprung up globally as doubts emerge about recycling, which used to seem like a win-win idea because consumers could keep consuming and the environment could stay pristine. But instead, for decades, the public believed its plastic was being recycled, only to find that 91% of it was not, according to a study in the peer-reviewed journal Science Advances, assessing all plastic from 1950-2015.

Vietnam is a focus of cleanup campaigns because it’s among the top five countries sending litter to sea, along with China, Indonesia, the Philippines, and Thailand…These Asian countries earned this marker because they import so much waste for processing from the rest of the world.

Tontoton says clients sign a letter committing to multiple strategies beyond offsets, including plastic substitutes and reduction. The company helps them offset or “neutralize” plastic already used, but this isn’t a “getaway car” to escape broader responsibility. “Plastic neutralization cannot solve the problem by itself.”

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.”

Wild West: Mercury Pollution in the Amazon Rainforest

Munduruku Indigenous people in the Tapajós basin – an epicenter of illegal gold mining in the Amazon rainforest – in southwestern Pará state have reported increasing encroachments upon their lands by armed “wildcat” miners known as “garimpeiros” since March 14, 2021. The Federal Prosecutor’s Office has warned of a potential for violence between local residents and the miners and urged the deployment of the federal police and other authorities to remove the trespassers. But the government has yet to act. The tension has escalated in recent weeks after a group of miners brought equipment to the area.

Illegal mining causes significant deforestation in the Brazilian Amazon and has been linked to dangerous levels of mercury poisoning, from mercury widely used to process the gold, in several Munduruku communities along the Tapajós basin. Indigenous people also fear that miners could spread the Covid-19 virus in their communities.

In a public statement on March 16, 2021 the Federal Prosecutor’s Office reported that a helicopter appeared to have escorted the miners and their equipment, suggesting the invasion is “an orchestrated action” by an organized crime group. The office also reported that the miners may be coordinating the invasion with a “small group” of Indigenous people who support the mining. Members of Munduruku communities who oppose the mining and have reported the invasions to the authorities say they have faced threats and intimidation. On March 19, 2021 armed men reportedly prevented a group of Munduruku Indigenous people from disembarking from their boats in an area within their territory. On March 25, 2021 in the Jacareacanga municipality, miners and their supporters forced their way into a building that houses the Wakoborun Women’s Association and other community organizations that have opposed the mining. The attackers destroyed furniture and equipment and set fire to documents, Indigenous leaders reported…

President Bolsonaro has signaled his aversion to protecting Indigenous lands. As a candidate, he vowed not to designate “one more centimeter” of land as Indigenous territory. His administration has halted the demarcation of Indigenous territories – there are 237 pending requests – leaving Indigenous communities even more vulnerable to encroachments, deforestation, and violence. The Munduruku territory is already demarcated. In 2020, Bolsonaro introduced a draft bill in Congress to allow mining and other commercial activities in Indigenous territories. The bill is pending in Congress and is listed as one of Bolsonaro’s priorities.

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.

A Lethal Combination: Rusty Tanks and Melting Ice in the Artic

A mining firm has paid a record $2bn fine over a huge oil spill that caused one of Russia’s worst environmental disasters. Norilsk Nickel, the world’s leading nickel and palladium producer, said it had paid the fine on March 10, 2021.The fuel spill in May 2021 saw 21,000 tonnes of diesel pour from one of the company’s storage tanks into rivers and lakes in Russia’s Arctic north…The penalty is the biggest ever issued for environmental damage in Russia, officials say.

How did the spill happen? The diesel oil began leaking on May 29, 2020. It is thought to have originated from a rusty storage tank at Norilsk Nickel’s power plant in Siberia.
Investigators believe the tank near Norilsk sank because of melting permafrost which weakened its supports. The Arctic had seen weeks of unusually warm weather – widely believed to be a symptom of global warming – prior to the disaster. The oil contaminated the Ambarnaya river and surrounding subsoil before drifting about 20km (12 miles) north of Norilsk. It then entered Lake Pyasino, which flows to the Kara Sea in the Arctic Ocean. In total, the oil contaminated a 350 sq km (135 sq mile) area…

The clean-up could cost $1.5bn and take between five and 10 years…Norilsk is already a well-known pollution hotspot, because of contamination from the industry that dominates the city.

How the Global Trade in Plastics Spills Over the Oceans

Low-value or “residual” plastics – those left over after more valuable plastic is recovered for recycling – are most likely to end up as pollution. So how does this happen? In Southeast Asia, often only registered recyclers are allowed to import plastic waste. But due to high volumes, registered recyclers typically on-sell plastic bales to informal processors…When plastic types were considered low value, informal processors frequently dumped them at uncontrolled landfills or into waterways.

Plastics stockpiled outdoors can be blown into the environment, including the ocean. Burning the plastic releases toxic smoke, causing harm to human health and the environment. When informal processing facilities wash plastics, small pieces end up in wastewater, which is discharged directly into waterways, and ultimately, the ocean.

The price of many recycled plastics has crashed in recent years due to oversupply, import restrictions and falling oil prices, (amplified by the COVID-19 pandemic). However clean bales of (polyethylene terephthalate) PET and (high-density polyethylene) HDPE are still in demand. In Australia, material recovery facilities currently sort PET and HDPE into separate bales. But small contaminants of other materials (such as caps and plastic labels) remain, making it harder to recycle into high quality new products. Before the price of many recycled plastics dropped, Australia baled and traded all other resin types together as “mixed plastics”. But the price for mixed plastics has fallen to zero and they’re now largely stockpiled or landfilled in Australia.

Beyond Deforestation–Toxic Waste Pollution at the Amazon Rainforest

Maria do Socorro explains in graphic detail the spate of ailments affecting newborns in her remote community in the Amazon: her grandson died after being born with his intestines outside his body, while others were missing organs or had undeveloped bones.  For the 56-year-old community leader, there is little doubt about the cause of these illnesses. She said the rainforest town had for years suffered from toxic waste pollution from the local operations of Norwegian aluminum producer Norsk Hydro.

Long a simmering environmental scandal in Brazil, the allegations were brought on to the international stage in February 2021 when Socorro’s community sued the Norwegian giant in a Dutch court, seeking damages for claims that “the incorrect disposal of toxic waste” from operations in the area had caused a variety of health ailments, polluted the rainforest and destroyed economic opportunities.

“If business can be global, why can’t justice? These companies have businesses everywhere, but then when they do something wrong they want to smother the possibility of people getting compensation,” said Pedro Martins, partner at law firm PGMBM, which is representing 40,000 alleged victims bringing the suit against Norsk Hydro…

Through local entities, Norsk Hydro runs three facilities — a bauxite mine, a refinery and a smelter — in Pará, a vast Amazonian state that is a flashpoint for illegal deforestation, gold mining and land-grabbing.  The company…denied that in 2018 pollutants from its facilities spilled over during heavy rains and polluted nearby rivers and earth….

Locals say bauxite, lead and aluminium pollution have turned the region’s rivers red. A study from the Evandro Chagas Institute, a Brazilian public health body, found in 2018 that the region’s waters were so polluted with industrial waste from the Norsk Hydro facilities that they “cannot be used for recreation, fishing, or human consumption”.

“I invite these Norwegians to come and bathe in our waters. I challenge them. They have good water there in Norway. Our wealth just goes there,” said Socorro, who heads Cainquiama, a group representing mainly indigenous people and quilombolas — the descendants of runaway slaves. Nearly all of the claimants in the suit have complained about chronic pain, hair loss and skin conditions. The suit also contains claims in relation to birth defects, such as those that have affected Socorro’s grandson, who was born with gastroschisis — a hole in the abdominal wall.

The case is a sensitive one for Norwegian investors and the government, which owns a 34 per cent stake in Norsk Hydro. Oslo has long attempted to hold Brasília to account for the environmental destruction of the Amazon, even publishing its own data on deforestation in the world’s largest rainforest.

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.

Gorillas, Murders and Making $1.50 per day-Congo Rainforest

Protecting the forests of Virunga National Park in eastern Democratic Republic of Congo – home to endangered mountain gorillas – could be described as one of the toughest jobs on the planet. In the past 12 months, more than 20 of the park’s staff have been murdered – and last week rebels were accused of killing the Italian ambassador to DR Congo, his security guard and driver in an attack within the park. “The level of sacrifice that’s involved in keeping this work going will always be the hardest thing to deal with,” says Emmanuel de Merode, who is in charge of more than 800 rangers at Virunga, Africa’s oldest and largest national park.


The Virunga park spans 7,800 sq km (3,000 sq miles) and is home to an astonishingly diverse landscape – from active volcanoes and vast lakes to rainforest and mountains.
The park was set up nearly 100 years ago to protect mountain gorillas, of which there are only 1,000 left in the world. It’s a national park which is part of the Congolese state which has been affected by civil war for the most of its recent history.

In  April 2020, 13 rangers were murdered in what park officials described as a “ferociously violent and sustained” attack by an armed group In January 2021, six rangers, patrolling the park’s boundary on foot, were killed in an ambush by militias. All of those who died were aged between 25 and 30.  It’s a national park which is part of the Congolese state which has been affected by civil war…. 

It’s estimated that a dozen or so armed militia groups survive off the park’s resources – poaching or chopping down wood to sell for fuel. DR Congo’s natural resources have been fought over for decades. The country – which is the size of mainland western Europe – has more mineral wealth, with diamonds, oil, cobalt and copper, than anywhere else on the planet. These are some of the elements essential to modern technology, making up key components in electric cars and smartphones.
Virunga is no different. It’s rich in resources underground as well as in nature and wildlife. But the two million people living in the region of the park mainly live on under $1.50 (£1.08) a day. This tussle for survival is not lost on Mr De Merode who sees protecting the park as essentially a social justice issue.

“It’s not a simple problem of protecting gorillas and elephants; it is overcoming an economic problem at the heart of one of the most horrific civil wars in history,” says Merode.

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.”

Natural Capital and Human Well-Being

What is the contribution of nature to the economy?… The breathable air, drinkable water and tolerable temperatures that allow humans to do everything they do, and the complex ecosystems that maintain them, tend to be taken for granted. Professor Dasgupta’s review on the Economics of Biodiversity does not seek to play on the heartstrings with tales of starving polar bears. Rather, it makes the hard-headed case that services provided by nature are an indispensable input to economic activity. Some of these services are relatively easy to discern: fish stocks, say, in the open ocean. Others are far less visible: such as the complex ecosystems within soil that recycle nutrients, purify water and absorb atmospheric carbon. These are unfamiliar topics for economists, so the review seeks to provide a “grammar” through which they can be analysed.

The report features its own illustrative production function, which includes nature. The environment appears once as a source of flows of extractable resources (like fish or timber). But it also shows up more broadly as a stock of “natural” capital. The inclusion of natural capital enables an analysis of the sustainability of current rates of economic growth. As people produce GDP, they extract resources from nature and dump waste back into it. If this extraction and dumping exceeds nature’s capacity to repair itself, the stock of natural capital shrinks and with it the flow of valuable environmental services. Between 1992 and 2014, according to a report published by the UN, the value of produced capital (such as machines and buildings) roughly doubled and that of human capital (workers and their skills) rose by 13%, while the estimated value of natural capital declined by nearly 40%. The demands humans currently place on nature, in terms of resource extraction and the dumping of harmful waste, are roughly equivalent to the sustainable output of 1.6 Earths (of which, alas, there is only the one)…Indeed, Professor Dasgupta argues that economists should acknowledge that there are in fact limits to growth. As the efficiency with which we make use of Earth’s finite bounty is bounded (by the laws of physics), there is necessarily some maximum sustainable level of GDP…

Professor Dasgupta hints at this problem by appealing to the “sacredness” of nature, in addition to his mathematical models and analytical arguments.

When Life Colonizes Plastic: the Deep Sea Wonder

The ocean deep, where pressure is high, light absent and nutrients scarce, is often seen as a desert. But, as with other deserts, it has oases. Hydrothermal vents, methane-gas seeps and whale corpses are hot spots for marine wildlife.  These natural loci of biodiversity are now being joined by unnatural ones made of plastic. Researchers obtained 33 objects from the deep sea in the South China Sea. Most were bags, bottles and food wrappers, but they picked up some derelict fishing ropes and traps as well…

These objects were teeming with life. When the researchers examined their finds in a laboratory, they found nearly 1,200 individual organisms representing 49 species of crustaceans, corals, echinoderms, flatworms, molluscs, polychaete worms and fungi. They also discovered evidence that some of these species were breeding. There were egg capsules from four different types of snail, and a cocoon from a flatworm known for parasitising crustaceans. This result suggests that accumulations of plastic are, indeed, benthic oases… As to why organisms colonise the objects in these accumulations, the short answer is, “because they are there”.

Who Will Rule the Arctic?


Rosatom joined the Arctic Economic Council*in February 2021. Rosatom is a Russian state-owned corporation supplying about 20% of the country’s electricity. The corporation mainly holds assets in nuclear power and machine engineering and construction. In 2018, the Russian government appointed Rosatom to manage the Northern Sea Route (NSR). The NSR grants direct access to the Arctic, a region of increasing importance for Russia due to its abundance of fossil fuels. Moreover, due to climate changes, the extraction of natural resources, oil and gas are easier than ever before.

Since Russia’s handover of NSR’s management, Rosatom’s emphasis on the use of nuclear power for shipping, infrastructure development and fossil fuel extraction is likely to become more prevalent in the Arctic region. Rosatom already operate the world’s first floating nuclear power plant in the Siberian port of Pevek and is the only company in the world operating a fleet of civilian nuclear-powered icebreakers…The company has numerous plans up its sleeves, among them to expand the fleet of heavy-duty nuclear icebreakers to a minimum of nine by 2035.

The Coral Reefs of the High Seas

While the terms “coral reef” and “high seas” are rarely combined in the same sentence, reef-building corals are found in Areas Beyond National Jurisdiction (ABNJ), the high seas. A study that has been published in the Frontiers in Marine Science identified 116 coral reefs in the Atlantic and Pacific Ocean, most of them located outside Marine Protected Areas (MPAs).

There is currently no comprehensive legal framework for the establishment of MPAs in ABNJ. Rather, initiatives to protect critical habitats on the high seas remain scattered throughout the legal mandates of organizations with different management purposes…. Yet, high seas MPAs are possible…. For example, the member countries of the Convention for the Protection of the Marine Environment of the North-East Atlantic (OSPAR) and the Convention on the Conservation of Antarctic Marine Life (CCAMLR) have established MPAs in ABNJ of the North Atlantic and Southern Ocean, respectively While these MPAs provide important advances in protecting biodiversity on the high seas, they still only cover a very small portion of the international ocean.

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.

When Shepherds are Wolves: States Culpability in Illegal Fishing

Ecuador portrays itself as a victim of illegal, unregulated and unreported (IUU) fishing by Chinese trawlers near the Galapagos islands. In fact, its fishing industry is just as bad…Since 2018 at least 136 large Ecuadorean fishing vessels have entered the Galapagos islands’ reserve, which covers 133,000 square km (51,000 square miles), says the director of the archipelago’s national park…

Many boats illegally transfer their catch on the high seas to larger vessels, which carry them to other markets. Under Ecuadorean law fishermen can sell endangered species like sharks or turtles if they catch them unintentionally. Some boats report half their catch as by-catch….The European Union, the biggest buyer of Ecuadorean tuna, has told the country to step up action against IUU or risk losing access to its market. In 2018 a committee within CITES, an international convention on trading in endangered species, recommended that its 183 members suspend trade in fish with Ecuador.

Its government is incapable of reining in a powerful industry. Fishing companies employ 100,000 people, and contribute $1.6bn a year, 1.5% of GDP to the economy. Ecuador’s tuna fleet, the largest in the eastern Pacific, has around 115 large mechanised ships. The rest of the fishing industry consists of more than 400 semi-industrial vessels and nodrizas, small boats with no machinery that catch a greater variety of fish…

Purse seine vessels and gear in this Google Earth image show the path of FADs belonging to just three vessels (typically vessels have about 100 FADs each) fishing in Central and Western Pacific (image from Parties to Nauru Agreement).

More controversial than purse seining and longlining is the use of fish aggregating devices (FADs). Industrial ships release these into the current that passes through the Galapagos islands’ protected area to attract prey, say green groups. Sometimes they fix goats’ heads on the devices to lure sharks, say Galapagans. Crews track them with GPS and surround them with nets when they leave the protected zones, entrapping turtles, sea lions, manta rays and sharks. Ecuadorean ships deploy more FADs than those of any other country, according to a study in 2015 by the Pew Charitable Trusts.

Climate Change Unlikely to Kill Amazon Rainforest

The current Earth system models used for climate predictions show that the Amazon rainforest is very sensitive to water stress. Since the air in the future is predicted to get warmer and drier with climate change, translating to increased water stress, this could have large implications not just for the forest’s survival, but also for its storage of CO2. If the forest is not able to survive in its current capacity, climate change could greatly accelerate.

Columbia Engineering researchers decided to investigate whether this was true, whether these forests are really as sensitive to water stress as what the models have been showing. In a study published in Science Advances, they report their discovery that these models have been largely over-estimating water stress in tropical forests.

The team found that, while models show that increases in air dryness greatly diminish photosynthesis rates in certain regions of the Amazon rainforest, the observational data results show the opposite: in certain very wet regions, the forests instead even increase photosynthesis rates in response to drier air…[In fact] As the trees become stressed, they generate more efficient leaves that can more than compensate for water stress.”…

“So much of the scientific research coming out these days is that with climate change, our current ecosystems might not be able to survive, potentially leading to the acceleration of global warming due to feedbacks,” Gentine added. “It was nice to see that maybe some of our estimates of approaching mortality in the Amazon rainforest may not be quite as dire as we previously thought.”

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.

Paper Parks, their Elephants and Marginal People

Since 2010 Chad has taken a step that other African countries are increasingly following. It handed management of its national park to an NGO. Since African Parks took over, the elephant population has begun to rise. In 2011 just one calf was born; in 2018, 127 were. The revival is emblematic of broader success that public-private partnerships (PPPs) are having in conserving some of the most precious parts of the planet.  Sixty years ago, when decolonization was sweeping the continent, the UN counted 3,773 “protected areas” in Africa and its surrounding waters. By 1990 the figure was 6,075; today it is 8,468. Some 14% of the continent’s land has been categorized as protected, according to the World Database on Protected Areas…

Most “protected areas” are “paper parks”, argues Peter Fearnhead, the chief executive of African Parks. In theory their demarcation denotes stewardship; in practice there is often very little care. Since its founding in 2000 the NGO has grown to manage 19 parks in 11 countries. It is the largest of an expanding number of ppp operators across the continent. The African Parks model relies on “three ms”, explains Mr Fearnhead: a clear mandate from a government (which keeps ownership of the area but hands over the running to the NGO); sound management; and money from donors such as the EU.

Zakouma is African Parks’ flagship operation. When it took over its management the priority was security. The national park was caught up in Chad’s civil conflicts in the 2000s, when rebel groups, some backed by Sudan, took on government forces. Janjaweed militias, notorious for mass murder and rape in Darfur, took advantage of the vacuum to slaughter Zakouma’s elephants and launch attacks on nearby villages.
The approach to security is a blend of low and high tech. It relies on residents of surrounding areas to alert it to poachers. Local intelligence is then combined with satellite tracking of the elephants. This helps anti-poaching rangers to know where to go.

Winning the support of people on the edge of the park has been crucial. Locals are happy to help report sightings of the Janjaweed, since they fear being robbed or murdered by them. African Parks also negotiates with nomads to ensure their caravans of camels do not go through the park.

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.

Turtle Eggs Can Fool Poachers

The InvestEGGator is used to reveal illegal trade networks and better understand what drives sea turtle egg poaching. The scientists deployed around a hundred of the fake eggs in sea turtle nests across four beaches in Costa Rica and waited. Each egg contained a GPS transmitter set to ping cell towers every hour, which would allow scientists to follow the InvestEGGator eggs on a smartphone app…Five of the deployed eggs were taken by unsuspecting poachers. The shortest route was roughly a mile, but one InvestEGGator traveled more than 80 miles, capturing what researchers were hoping for: the complete trade route, from the beach to the buyer. “Having that moment where the trade chain was complete….that was obviously a very big moment,” says Pheasey.

The InvestEGGator was the invention of Kim Williams-Guillén… The trick, says Williams-Guillén, was designing a device that looked and felt like a sea turtle egg while being precise enough to reveal trade routes. Sea turtle eggs are the size of ping pong balls, but unlike brittle chicken eggs, their shell is leathery and pliable. “Making [the trackers] look like eggs from far away was not going to be an issue, it was more making them feel like turtle eggs,” says Williams-Guillén. “One of the ways that [poachers] know that a turtle egg is good when they’re sorting their eggs is that it’s still soft and squishy.”…

Of the nests containing decoy eggs, a quarter were illegally harvested. Some of the eggs failed to connect to a GPS signal, while other eggs were spotted by poachers and tossed aside. Five of those poached eggs gave the team useful tracking data…This illegal trade network revealed that eggs are sold and consumed locally… The routes they discovered also suggest that most egg poachers in the area are individuals looking to make quick money, not an organized network.

De-Extinction: Horse Revival


A little baby horse named Kurt is a symbol of renewed hope for the survival of his kind. Born on 6 August 2020, he is the world’s first ever successfully cloned Przewalski’s horse, an endangered wild horse native to the steppes of central Asia. What makes Kurt even more exciting is that he was cloned from genetic material cryopreserved 40 years ago – reviving genetic diversity thought to have been lost decades ago…

Przewalski’s horses roaming the steppes declined dramatically after World War II, due to a combination of factors such as hunting, competition with livestock as humans moved into their territory, and severe winters. The last confirmed sighting of a Przewalski’s horse in the wild was in 1969. Luckily, some of the horses still remained in zoos. But not many. A total of 12 horses made up the ancestors of a captive breeding program – 11 Przewalski’s horses wild-caught between 1899 and 1902, and another caught in 1947. Thanks to this breeding program, there are around 2,000 individuals today. That’s incredibly impressive, but the growing population isn’t without problems.

Those 12 ancestor individuals represent what is known as a population bottleneck – when a species undergoes a severe reduction in numbers. From that point, a population can recover, but it can also be the beginning of the end. One of the reasons for that is lower genetic diversity. With less variation, a population is less able to adapt to potential stressors or changes to their environment…

Enter a Przewalski’s horse named Kuporovic, who lived from 1975 to 1998. An analysis of the captive breeding pedigree revealed that Kuporovic’s genome had unique ancestry from two wild founders. This meant he offered significantly more genetic variation than any of his living relatives, so in 1980, scientists took a sample and preserved it in San Diego Zoo’s Frozen Zoo.  San Diego Zoo partnered with wildlife conservation group Revive & Restore and pet cloning company ViaGen Equine to create an embryo using Kuporovic’s genetic material. This embryo was implanted in a domestic horse (Equus ferus caballus) surrogate, and was born healthy after a normal pregnancy.

When Restoration Is Eradication: Palmyra Atoll

On the Palmyra Atoll in the central Pacific Ocean, conservation biologists are in the midst of a massive, unprecedented experiment. They are trying to rid this remote island of all but a few coconut palms. The gangly tree is an icon of idyllic tropical islands, but also an aggressive invasive species that crowds out native plants and animals. By removing 99% of Palmyra’s millions of palms, biologists hope to create more room on the atoll’s three dozen islets for indigenous forests and seabirds, including the world’s second largest colony of red-footed boobies…

Red footed booby

Ripping out the palms has long been on the list of restoration projects on Palmyra. First, however, managers decided to attack another invader, black rats, which likely arrived on ships during World War II. With no predators, rats multiplied into the tens of thousands. They ate the seeds and gnawed the saplings of native trees and attacked seabird colonies, including those of sooty terns, which nest on the ground. Rats are the key suspects behind the absence on Palmyra of eight other species of ground or burrow-nesting birds, including shearwaters and petrels, all found on central Pacific islands that have remained rat-free. The first attempt to eradicate the rats in 2002 failed, partly because Palmyra’s abundant land crabs out-competed the rodents for the poisonous bait. The crabs’ physiology allowed them to eat the poison—the anticoagulant brodifacoum—without ill effect.

The second effort was successful only after [researchers] radio-collared rats and discovered that the rodents liked to hang out in the crowns of coconut palms. The crowns became a convenient platform for stashing cotton gauze sacks of poison bait, delivered by workers firing slingshots or dangling from helicopters. Crabs do not reach the palm tops.

Once rats were exterminated in 2011, researchers watched with delight as native tree saplings began to spring from the forest floor. There were also happy surprises. Scientists discovered two additional species of land crabs that had likely gone undetected because voracious rats suppressed their numbers. And researchers realized they were no longer being bitten by Asian tiger mosquitoes, a pest that attacks during the day and can carry dengue and yellow fever. It appears the mosquitoes depended on rats rather than humans or birds for blood meals…

Electrical Bacteria as Ecosystem Engineers

Electric bacteria join cells end to end to build electrical cables able to carry current up to 5 centimetres through mud. The adaptation, never seen before in a microbe, allows these so-called cable bacteria to overcome a major challenge facing many organisms that live in mud: a lack of oxygen. Its absence would normally keep bacteria from metabolizing compounds, such as hydrogen sulfide, as food. But the cables, by linking the microbes to sediments richer in oxygen, allow them to carry out the reaction long distance…

The more researchers have looked for “electrified” mud, the more they have found it, in both saltwater and fresh. They have also identified a second kind of mud-loving electric microbe: nanowire bacteria, individual cells that grow protein structures capable of moving electrons over shorter distances. These nanowire microbes live seemingly everywhere—including in the human mouth… Scientists are pursuing practical applications, exploring the potential of cable and nanowire bacteria to battle pollution and power electronic devices…

The Center for Electromicrobiology was established in 2017 by the Danish government. Among the challenges the center is tackling is mass producing the microbes in culture…Cultured bacteria would also make it easier to isolate the cable’s wires and test potential applications for bioremediation and biotechnology…

Electrical bacteria are everywhere. In 2014, for example, scientists found cable bacteria in three very different habitats in the North Sea: an intertidal salt marsh, a seafloor basin where oxygen levels drop to near zero at some times of the year, and a submerged mud plain just off the coast…Elsewhere, researchers have found DNA evidence of cable bacteria in deep, oxygen-poor ocean basins, hydrothermal vent areas, and cold seeps, as well as mangrove and tidal flats in both temperate and subtropical regions.

Nanowire bacteria are even more broadly distributed. Researchers have found them in soils, rice paddies, the deep subsurface, and even sewage treatment plants, as well as freshwater and marine sediments. They may exist wherever biofilms form, and the ubiquity of biofilms provides further evidence of the big role these bacteria may play in nature.

The microbes also alter the properties of mud, says Sairah Malkin, an ecologist at the University of Maryland Center for Environmental Science. “They are particularly efficient … ecosystem engineers.” Cable bacteria “grow like wildfire,” she says; on intertidal oyster reefs, she has found, a single cubic centimeter of mud can contain 2859 meters of cables, which cements particles in place, possibly making sediment more stable for marine organisms.

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.

No Clean-Up, No Justice: Ogoniland, Nigeria

The UN Environment Programme in 2011 proposed the creation of a $1 billion fund to repair the damage done by decades of crude spills in the Ogoniland area in southeastern Nigeria. However, progress has been poor and the little work that has been done is sub-standard, advocacy groups including Amnesty International reported in June 2020.  “Research reveals that there is still no clean-up, no fulfillment of ‘emergency’ measures, no transparency and no accountability for the failed efforts, neither by the oil companies nor by the Nigerian government,” the groups said.

Shell’s Nigerian unit pumped oil in Ogoniland until 1993, when the company withdrew amid increasing protests against its presence. Even though the Hague-based company no longer produces crude in the area, a joint venture operated by Shell Petroleum Development Company, or SPDC, still owns pipelines that crisscross the region.

A government agency responsible for overseeing the clean-up, the Hydrocarbon Pollution Remediation Project, known as Hyprep, was finally set up in 2017 after several false starts, but it’s failing to deliver. …“Hyprep is not designed, nor structured, to implement a project as complex and sizable as the Ogoniland clean-up,” the report cites UNEP as saying in 2019

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.

Crude Oil in the Bile of Fish: BP Horizon Oil Spill

Since the 2010 BP oil spill, marine scientists at the University of South Florida (USF) have sampled more than 2,500 individual fish representing 91 species from 359 locations across the Gulf of Mexico and found evidence of oil exposure in all of them, including some of the most popular types of seafood. The highest levels were detected in yellowfin tuna, golden tilefish and red drum. The study represents the first comprehensive, Gulf-wide survey of oil pollution launched in response to the Deepwater Horizon spill.

Over the last decade have examined the levels of polycyclic aromatic hydrocarbons (PAHs), the most toxic chemical component of crude oil, in the bile of the fish. Bile is produced by the liver to aid in digestion, but it also acts as storage for waste products.

“We were quite surprised that among the most contaminated species was the fast-swimming yellowfin tuna as they are not found at the bottom of the ocean where most oil pollution in the Gulf occurs,” said lead author Erin Pulster…Pulster says it makes sense that tilefish have higher concentrations of PAH because they live their entire adult lives in and around burrows they excavate on the seafloor and PAHs are routinely found in Gulf sediment. However, their exposure has been increasing over time, as well as in other species, including groupers, some of Florida’s most economically important fish. …

Oil pollution hot spots were also found off major population centers, such as Tampa Bay, suggesting that runoff from urbanized coasts may play a role in the higher concentrations of PAHs. Other sources include chornic low-level releases from oil and gas platforms, fuel from boats and airplanes and even natural oil seeps — fractures on the seafloor that can ooze the equivalent of millions of barrels of oil per year.

Our Biggest Weakness: Weak Biodefenses + Malicious Viruses

The coronavirus that has killed over 180,000 people worldwide was not created with malice. Analysis of its genome suggests that, like many new pathogens, it originated by natural selection rather than human design. But …“Covid-19 has demonstrated the vulnerability of the US and global economy to biological threats, which exponentially increases the potential impact of an attack,” says Richard Pilch of the Middlebury Institute of International Studies. In theory, bioweapons are banned. Most countries in the world are party to the Biological Weapons Convention (BWC) of 1975, which outlaws making or stockpiling biological agents for anything other than peaceful purposes. But some countries probably make them secretly, or keep the option close at hand. America accuses North Korea of maintaining an offensive biological-weapons programme, and alleges that China, Iran and Russia dabble in dual-use biolgical research (for peaceful and military usage) research. Toxins like ricin have also been bought and sold on shady recesses of the internet known as the dark web.

Germ warfare briefly rose to prominence in September 2001, when letters laced with anthrax spores were mailed to American news organisations and senators, killing five people. That was a wake-up call. Public health became part of national security. BioWatch, a network of aerosol sensors, was installed in more than 30 cities across America. But in recent years threats from chemical weapons, like the sarin dropped by Syria’s air force and the Novichok smeared on door handles by Russian assassins, took priority.

Though the Trump administration published a national biodefence strategy in 2018, it shut down the National Security Council’s relevant directorate and proposed cuts to the laboratories that would test for biological threats. Funding for civilian biosecurity fell 27% between fiscal years 2015 and 2019, down to $1.61bn—less than was spent on buying Black Hawk helicopters.

Yet many pathogens used as weapons tend to differ from respiratory viruses in important ways. Those like anthrax, caused by bacteria which form rugged and sprayable spores, but do not spread from human to human, have the advantage of minimising the risk of rebound to the attacker. With the notable exception of smallpox—a highly contagious and lethal virus that was eradicated in 1979 but preserved by the Soviet Union for use against America (but not Europe), and now exists only in two laboratories, in America and Russia—most biological weapons would therefore have more localised effects than the new coronavirus.

Even so, the slow and stuttering response to the pandemic has exposed great weaknesses in how governments would cope…demonstrating that every part of public-health infrastructure is either broken or stretched to the max. The centrepiece of America’s biosurveillance programme, a network of laboratories designed for rapid testing, failed, says Mr Koblentz, while the national stockpile of face masks had not been substantially replenished in over a decade. Would-be attackers will take note.

In 2016 American intelligence agencies singled out genome editing as a national-security threat for the first time. Two years later a major study by the National Academies of Sciences, Engineering, and Medicine warned that synthetic biology, a potent set of methods for tinkering with or creating organisms, could, in time, be used to re-create viruses like smallpox or make existing pathogens more dangerous, such as resistant to antibiotics. In 2011 Dutch and Japanese scientists said that they had created a version of bird flu that could be transmitted between mammals by the respiratory route—an announcement that prompted the Netherlands to treat the relevant academic papers as sensitive goods subject to export controls.

In January 2020 Canadian scientists funded by an American biotech company used synthetic DNA from Germany to synthesise a microbe closely related to smallpox, indicating the ease with which it could be done. “If a potential bad actor pursues a weapons capability using sars-cov-2, the virus is now attainable in laboratories all around the world, and blueprints for assembling it from scratch have been published in the scientific literature.”

 The trouble is that biodefence has evolved slowly, says Dan Kaszeta, a former biological weapons adviser to the White House. Compact devices that can detect chemical threats and warn soldiers to don a gas mask have long been available. “That doesn’t exist for anthrax or any of the other aerosol pathogens,” says Mr Kaszeta. “Telling the difference between an anthrax spore and a bit of tree pollen is not something you can do in a couple of seconds.”

Naked Commercial Whaling and Toxic Whale Meat

Scientific “research” was also the reason Japan’s government gave for continuing to kill whales in the vast Southern Ocean after a global moratorium on commercial whaling came into force in 1985. But international criticism along with environmental groups’ attempts to sabotage the annual hunt proved too costly to Japan’s reputation and purse (the government bankrolled the hunt). In late 2018 Japan declared it was giving up killing in the Southern Ocean .

The Southern Ocean is now a sanctuary. But it comes at a cost. Japan walked out of the International Whaling Commission (IWC), accusing the anti-whaling members of failing to appreciate the cultural significance of whaling in Japan and of imposing their values on others. Freed from the IWC’s strictures, the government said commercial whaling would resume in Japan’s own extensive waters. But…whaling in home waters is troubling. Most whale populations in the Southern Ocean are healthy. In Japanese waters, stocks are less bountiful….

The whaling lobby is powerful in Japan. For now, the subsidies continue, supposedly to help ease the switch to nakedly commercial whaling but they coud be gone in two or three years. Other fleets complain that whaling gets far more than its fair share of subsidies for fisheries.

The challenges are immense. Whalemeat consumption has fallen from 230,000 tonnes a year in the early 1960s to 3,000 tonnes today, and whale is no longer cheap. Local whales have higher accumulations of toxins (such as a mercury) than those in the Southern Ocean. One packager of sashimi admits he sources his whale meat from Norway.

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.

Can Traditional Medicine Cure COVID-19? China’s Take

Around the world officials are advising people to be wary of alternative treatments for covid-19. The opposite is true in China, where remedies known as traditional Chinese medicine (TCM) are being heavily promoted by the state. In January 2020, as the crisis escalated, the health ministry listed TCM treatments among those it recommended for the disease. It sent nearly 5,000 specialists to Hubei to administer them to patients (including sufferers at a sports centre in Wuhan that was turned into a TCM hospital for people with mild symptoms). Now China is keen to promote its remedies abroad.  TCM practitioners have joined Chinese medical teams sent to help manage outbreaks in Cambodia, Iraq and Italy. In mid-March, 2020 state media quoted a Tanzanian health official saying that China’s use of TCM for covid-19 may be “a model” for Africa to follow…

The use of animals in TCM sometimes involves appalling cruelty. One of the TCM remedies that the health ministry has recommended for use in the treatment of covid-19 patients includes powdered bear bile. In China this is often extracted from live bears kept in grim farms even though its active ingredient can be created synthetically. In February 2020 China banned the sale of wild animals as food—close contact in markets between live specimens and merchants may have helped the coronavirus to leap from animal to human. But the new rules do not prevent trappers and breeders from selling animal parts for use in TCM.

Officials do not say that traditional remedies can cure covid-19. But they do claim that TCM can reduce death rates by preventing patients with mild or moderate symptoms from developing more serious ones. They also say that TCM can speed up recovery. A website set up by China Daily, a state newspaper, called “Fighting covid-19 the Chinese way”, says that TCM can “remove the trash which causes illness”, leaving the virus “no room to survive”.

Oceans Restored: the 2050 Deadline

A study published in Nature on April 2, 2020 claims that marine ecosystems could recover in just 30 years because of the growing success of conservation efforts and the ocean’s remarkable resilience. Some of these conservation efforts include the increase in Marine Protected Areas (MPAs) from less than 1 percent in 2000 to almost 8 percent today and the restoration of key habitats such as seagrass beds and mangroves

One great success is the restoration of humpback whales that migrate between Antarctica and eastern Australia. Their numbers have rebounded from a few hundred in 1968 to more than 40,000 today. Sea otters in Western Canada have also jumped from dozens in 1980 to thousands. Green turtles in Japan, grey seals and cormorants in the Baltic and elephant seals in the United States have all also made remarkable comebacks. However, “If we don’t tackle climate change and raise the ambition and immediacy of these efforts, we risk wasting our efforts,” Duarte, one of the authors of the study, told BBC News. The initial price tag on all this is hefty: $10 to $20 billion a year until the 2050 recovery date.

Better Alive than Dead: The Crocodile Trade

Around 6m tonnes of bush meat are thought to come out of the Congo Basin each year… The trade has emptied out parts of the forest; 39% of it is at severe risk of over-hunting, the study says. Everything from bonobos (an endangered species of ape) to cobras, antelopes and, occasionally, elephants, appear at market stalls in Mbandaka.

Over-hunting has made life more dangerous for crocodile hunters. The number of dwarf crocodiles, once common in the Congo river, is dwindling. So hunters have to chase the ferocious Nile crocodile instead. There are plenty of those. Their scaly bodies stretch to six metres and they often kill humans. Stalkers in canoes go after them at night, shining a torch while stirring the water. “The crocodile does not like that,” says Mr Nyalowala. “He begins to writhe and then comes to attack.” As the animal pounces so do its pursuers, spearing it.

A live crocodile fetches more than a dead one in the markets in Mbandaka, so hunters bind their jaws and transport them some 200km downstream in their canoes. They sell for around $150 each. A teacher at a state school, by comparison, earns around $170 a month, though many did not get paid at all last year.

How to Create a National Park? Beat Up and Intimidate Indigenous Peoples

Armed ecoguards partly funded by the conservation group WWF to protect wildlife in the Republic of the Congo beat up and intimidated hundreds of Baka pygmies living deep in the rainforests, according to a UNDP investigation. A team of investigators sent to northern Congo by the UN Development Programme (UNDP) to assess allegations of human rights abuses gathered “credible” evidence from different sources that hunter-gatherer Baka tribespeople living close to a proposed national park had been subjected to violence and physical abuse from the guards over years, according to a leaked draft of the report obtain by the Guardian in February 2020.

The allegations, reported to the UN in 2019, included Baka tribespeople being beaten by the ecoguards, the criminalisation and illegal imprisonment of Baka men, summary evictions from the forest, the burning and destruction of property, and the confiscation of food.  In addition, the UNDP’s social and environmental compliance unit heard how the ecoguards allegedly treated the Baka men as “sub-human” and humiliated some Baka women by forcing them to take off their clothes and “be like naked children”.

The report says: “These beatings occur when the Baka are in their camps along the road as well as when they are in the forest. They affect men, women and children. Other reports refer to ecoguards pointing a gun at one Baka to force him to beat another and guards taking away the machetes of the Baka, then beating them with those machetes.

“There are reports of Baka men having been taken to prison and of torture and rape inside prison. The widow of one Baka man spoke about her husband being so ill-treated in prison that he died shortly after his release. He had been transported to the prison in a WWF-marked vehicle.”

The draft report, dated 6 January 2020, adds: “The violence and threats are leading to trauma and suffering in the Baka communities. It is also preventing the Baka from pursuing their customary livelihoods, which in turn is contributing to their further marginalisation and impoverishment.”

The $21.4m (£16.6m) flagship Tridom 11 project in northern Congo set up in 2017 with money from the WWF, UNDP, the European commission, US and Congolese governments and the Global Environment Facility, as well as logging and palm oil conglomerates, includes as its centrepiece a 1,456 sq km area of forest known as Messok Dja.

This global biodiversity hotspot is rich in wildlife, including elephants, gorillas and chimpanzees, and has been lived in and used for the hunting of small game by the semi-nomadic Baka tribes for millennia. The WWF has pressed for it to be designated a protected area, or national park, for 10 years, on the grounds that it will reduce wildlife crime and act as an ecological corridor linking national parks in neighbouring Cameroon.

The WWF says the ecoguards were employed by the Congolese government, but admits contributing to their training and wages along with other funders through the Tridom interzone project (ETIC), a Congo government collaboration with WWF. It adds that there are no legal restrictions preventing Baka using the forests….The investigators also identified multiple failures of the UNDP to adhere to human rights policies and standards, and said little consideration had been given to the impact of the project on the Baka peoples….Investigators also said they found no evidence that the UNDP had taken into account the risk of co-financing the project with palm oil and logging companies whose work by its nature threatens large-scale biodiversity loss.

The report strongly criticises the way conservation is practised in central Africa. “The goal of establishing Messok Dja as a protected area was pursued by following the established patterns of conservation projects in the Congo Basin, which largely exclude indigenous peoples and treat them as threats rather than partners,” it says.

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.

Excerpts from How artificial shrimps could change the world, Economist, Feb. 28, 2020

Human and Environmental Costs of Low-Carbon Technologies

Substantial amounts of raw materials will be required to build new low-carbon energy devices and infrastructure.  Such materials include cobalt, copper, lithium, cadmium, and rare earth elements (REEs)—needed for technologies such as solar photovoltaics, batteries, electric vehicle (EV) motors, wind turbines, fuel cells, and nuclear reactors…  A majority of the world’s cobalt is mined in the Democratic Republic of Congo (DRC), a country struggling to recover from years of armed conflict…Owing to a lack of preventative strategies and measures such as drilling with water and proper exhaust ventilation, many cobalt miners have extremely high levels of toxic metals in their body and are at risk of developing respiratory illness, heart disease, or cancer.

In addition, mining frequently results in severe environmental impacts and community dislocation. Moreover, metal production itself is energy intensive and difficult to decarbonize. Mining for copper,and mining for lithium has been criticized in Chile for depleting local groundwater resources across the Atacama Desert, destroying fragile ecosystems, and converting meadows and lagoons into salt flats. The extraction, crushing, refining, and processing of cadmium can pose risks such as groundwater or food contamination or worker exposure to hazardous chemicals. REE extraction in China has resulted  threatens rural groundwater aquifers as well as rivers and streams.

Although large-scale mining is often economically efficient, it has limited employment potential, only set to worsen with the recent arrival of fully automated mines. Even where there is relative political stability and stricter regulatory regimes in place, there can still be serious environmental failures, as exemplified by the recent global rise in dam failures at settling ponds for mine tailings. The level of distrust of extractive industries has even led to countrywide moratoria on all new mining projects, such as in El Salvador and the Philippines.

Traditional labor-intensive mechanisms of mining that involve less mechanization are called artisanal and small-scale mining (ASM). Although ASM is not immune from poor governance or environmental harm, it provides livelihood potential for at least 40 million people worldwide…. It is also usually more strongly embedded in local and national economies than foreign-owned, large-scale mining, with a greater level of value retained and distributed within the country. Diversifying mineral supply chains to allow for greater coexistence of small- and large-scale operations is needed. Yet, efforts to incorporate artisanal miners into the formal economy have often resulted in a scarcity of permits awarded, exorbitant costs for miners to legalize their operations, and extremely lengthy and bureaucratic processes for registration….There needs to be a focus on policies that recognize ASM’s livelihood potential in areas of extreme poverty. The recent decision of the London Metals Exchange to have a policy of “nondiscrimination” toward ASM is a positive sign in this regard.

A great deal of attention has focused on fostering transparency and accountability of mineral mining by means of voluntary traceability or even “ethical minerals” schemes. International groups, including Amnesty International, the United Nations, and the Organisation for Economic Co-operation and Development, have all called on mining companies to ensure that supply chains are not sourced from mines that involve illegal labor and/or child labor.

Traceability schemes, however, may be impossible to fully enforce in practice and could, in the extreme, merely become an exercise in public relations rather than improved governance and outcomes for miners…. Paramount among these is an acknowledgment that traceability schemes offer a largely technical solution to profoundly political problems and that these political issues cannot be circumvented or ignored if meaningful solutions for workers are to be found. Traceability schemes ultimately will have value if the market and consumers trust their authenticity and there are few potential opportunities for leakage in the system…

Extended producer responsibility (EPR) is a framework that stipulates that producers are responsible for the entire lifespan of a product, including at the end of its usefulness. EPR would, in particular, shift responsibility for collecting the valuable resource streams and materials inside used electronics from users or waste managers to the companies that produce the devices. EPR holds producers responsible for their products at the end of their useful life and encourages durability, extended product lifetimes, and designs that are easy to reuse, repair, or recover materials from. A successful EPR program known as PV Cycle has been in place in Europe for photovoltaics for about a decade and has helped drive a new market in used photovoltaics that has seen 30,000 metric tons of material recycled.

Beauty Secrets: Donkeys Exterminated for their Skin Collagen

Over the past 6 years, Chinese traders have been buying the hides of millions of butchered donkeys from developing countries and shipping them to China, where they’re used to manufacture ejiao, a traditional Chinese medicine… Ejiao, in use for thousands of years, purportedly treats or prevents many problems, including miscarriage, circulatory issues, and premature aging, although no rigorous clinical trials support those claims. The preparation combines mineral-rich water from China’s Shandong province and collagen extracted from donkey hides, traditionally produced by boiling the skins in a 99-step process. Once reserved for China’s elites, ejiao is now marketed to the country’s booming middle class, causing demand to surge

Despite government incentives for new donkey farmers, farms in China can’t keep up with the exploding demand, which the Donkey Sanctuary currently estimates at 4.8 million hides per year. Donkeys’ gestation period is one full year, and they only reach their adult size after 2 years. So the industry has embarked on a frenzied hunt for donkeys elsewhere. This has triggered steep population declines. In Brazil, the population dropped by 28% between 2007 and 2017, according to the new report.

African populations are crashing, too, says Philip Mshelia, an equine veterinarian and researcher at Ahmadu Bello University in Zaria, Nigeria. After buying donkeys at markets, traders often drive large herds to slaughter, sometimes covering hundreds of kilometers with no rest, food, or water. Those transported by truck fare worse: Handlers tie their legs together and sling them onto piles or strap them to the top of the truck, Mshelia says. Animals that survive the journey—many with broken or severed limbs—are unloaded by the ears and tails and tossed in front of a slaughterhouse. Some meet their end in an open field where humans await them with hammers, axes, and knives.

For donkey owners, selling their animal means quick cash—now more than $200 in parts of Africa…

Ironically, the booming ejiao trade, along with a developing donkey dairy industry in Eastern Europe, has stirred scientific interest in donkeys.  Zhen Shenming, a reproductive biologist at the China Agricultural University in Beijing, says Chinese efforts are focused on increasing yields, for instance through artificial insemination…Chinese breeders are also testing new nutrition programs that expedite growth, leading to an adult-size donkey in only 18 months…

“They are very observant and sentient animals, and they create very strong bonds with other donkeys.” That’s one reason the current slaughtering practice, in which the animals often await their turn while watching other donkeys being beaten unconscious, slaughtered, and skinned is abhorrent.  “They’re certainly quite well aware of what’s happening and what’s to come,” McLean says.

Left to their Own Bad Devices: the Future of Ogoni Land in Nigeria

The decades-overdue clean-up of Ogoniland, after years of oil spills from the pipelines that criss-cross the region, is finally under way. But the billion-dollar project — funded by Nigeria’s national oil company and Royal Dutch Shell — is mired in allegations of corruption and mismanagement.  “We are not pleased with what is going on,” said Mike Karikpo, an attorney with Friends of the Earth International and a member of the Ogoniland team that negotiated the creation of the Hydrocarbon Pollution Remediation Project (Hyprep), the government body running the clean-up… 

Nigeria is Africa’s biggest oil producer, pumping out about 1.8m barrels per day. It provides roughly 90 per cent of the country’s foreign exchange and more than half of government revenues.  The clean-up began only the summer 2019, about a year after the first of an expected five tranches of $180m in funding was released to Hyprep. Mr Karikpo complains of a lack of transparency, alleging that planning, budgeting and awarding of contracts took place behind closed doors. Work started at the height of the rainy season, washing away much of the progress as contaminated soil collected for treatment was swept back into the environment…

Ogoniland, like the broader Niger Delta, has become more polluted and development has stalled, with little to show for the billions of dollars in crude that has been extracted. Critics have now accused Hyprep of being, like much of Nigeria’s oil sector, a vehicle for political patronage and graft. This year 16 companies were awarded contracts for the first phase of the clean-up, which — to the consternation of critics — focuses on the least contaminated parts of Ogoniland.

An investigation by the news site Premium Times found that almost all the companies were set up for other purposes, including poultry farming, car sales and construction, and had no experience of tackling oil pollution.  Meanwhile, insiders have questioned Hyprep’s capacity to handle such a massive project…

Shell and Hyprep have rejected the criticism.  Shell, which closed its Ogoniland operations in 1993, said it accepted responsibility “for spills arising from its operations”, but that some of the blame for the pollution must go to thieves who illegally tapped into pipelines and makeshift refining operations in the Delta’s creeks

540 Katrina Oil Spills Equal an Exxon Valdez Disaster

The federal agency overseeing oil and gas operations in the Gulf of Mexico after hurricane Katrina reported that more than 400 pipelines and 100 drilling platforms were damaged. The U.S. Coast Guard, the first responder for oil spills, received 540 separate reports of spills into Louisiana waters. Officials estimated that, taken together, those leaks released the same amount of oil that the highly publicized 1989 Exxon Valdez disaster spilled into Alaska’s Prince William Sound — about 10.8 million gallons…

While hurricanes gain speed due to the effects of climate change, the push for oil leasing in the Gulf of Mexico shows no sign of slowing down. In 2014, the Obama administration opened up 40 million new acres in the Gulf for oil and gas development. Four years later, the Trump administration announced plans to open up most of the rest, in what would be the largest expansion of offshore oil and gas drilling in U.S. history. Many of these 76 million acres are to be offered at reduced royalty rates to encourage additional near-shore drilling in Louisiana waters…

“In the Gulf, storms are predicted to be less frequent but more intense when they do come,” said Sunshine Van Bael, an ecologist at Tulane University who evaluated damage to marsh ecosystems from the BP oil spill. “One thing that storms do is, if oil has been buried underneath the marsh because it wasn’t rehabilitated, a storm could come along and whip that back up to the surface. So, the aftereffects of the oil spills might be greater [with climate change] since the storms are predicted to be more intense.”…

In 2009, a class-action lawsuit against Murphy Oil Corp. ended in a settlement requiring the company to pay $330 million to 6,200 claimants, including owners of about 1,800 homes in St. Bernard Parish. The damage occurred when one of Murphy’s storage tanks floated off its foundation during Katrina and dumped over a million gallons of crude oil into a square-mile segment of Meraux and Chalmette….

To date, more than $19 million has been paid out from the federal Oil Spill Liability Trust Fund to reimburse at least two oil companies for costs they incurred cleaning up oil they spilled during Katrina…

“We don’t normally penalize [companies] for act of God events,” Greg Langley of the Department of Environmental Quality said. “We just get right to remediation.”

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.

Viva Over-Fishing! Addicted to Over-Consumption of Fish

In 2015 world leaders signed up to a long list of sustainable development goals, among them an agreement to limit government subsidies that contribute to overfishing. Negotiators at the World Trade Organisation (wto) were told to finish the job “by 2020”. They have missed their deadline. Overfishing is a tragedy of the commons, with individuals and countries motivated by short-term self-interest to over-consume a limited resource. By one measure, the share of fish stocks being fished unsustainably has risen from 10% in 1974 to 33% in 2015.

Governments make things worse with an estimated $22bn of annual subsidies that increase capacity, including for gear, ice, fuel and boat-building. One study estimated that half of fishing operations in the high seas (waters outside any national jurisdiction) would be unprofitable without government support.

 Trade ministers were supposed to sort it all out at WTO meeting in December in Kazakhstan. But the meeting was postponed till June 2020. Moreover, the murky nature of subsidies for unregulated and unreported fishing makes their work unusually difficult. Governments do not have lines in their budget that say “subsidies for illegal fishing”, points out Alice Tipping of the International Institute for Sustainable Development, a think-tank.

Negotiators are trying to devise a system that would alert governments to offending boats, which would become ineligible for future subsidies. That is tangling them up in arguments about what to do when a boat is found in disputed territory, how to deal with frivolous accusations and how to treat boats that are not associated with any country offering subsidies.

When it comes to legal fishing of overfished stocks, it is easier to spot the subsidies in government budget lines, but no easier to agree on what to do about them. America and the European Union, for example, have been arguing over whether to allow subsidies up to a cap, or whether to ban some subsidies and take a lenient approach to the rest. The EU favours the second option, arguing that where fisheries are well-managed, subsidies are not harmful. To others this looks like an attempt to ensure any eventual deal has loopholes.

Further complicating matters is a long-running row about how to treat developing countries. All WTO members agree that some need special consideration. But as an American representative pointed out at a recent WTO meeting, 17 of the world’s 26 most prolific fishing countries are developing ones. That means broad carve-outs for them would seriously weaken any deal.

China, both the world’s biggest fisher and biggest subsidiser of fishing, has proposed capping subsidies in proportion to the number of people in each country who work in the industry. But it is the world leader here, too, with 10m at the last count (in 2016). Other countries fear such a rule would constrain China too little.

When the Fish are Gone: As Bad as it Could Get in the Yangtze River

China imposed a 10-year commercial fishing ban in January 2020  on the Yangtze – the first ever for Asia’s longest river – in a bid to protect its aquatic life.  Facing dwindling fish stocks and declining biodiversity in the 6,300km (3,915-mile) river, the Chinese government decided seasonal moratoriums were not enough. The ban will be applied at 332 conservation sites along the river. It will be extended to cover the main river course and key tributaries by January 1 2021, according to a State Council notice.   Dam-building, pollution, overfishing, river transport and dredging had worsened the situation for the waterway’s aquatic species.  Fishermen using nets with smaller holes and illegal practices such as the use of explosives or electrocution have also contributed to the river’s decline

 President Xi Jinping warned that the Yangtze River had become so depleted that its biodiversity index was as bad as it could get, saying it had reached what could be described as the “no fish” level… Back in 1954, the annual catch from the Yangtze was about 427,000 tonnes, but in recent years it had been less than 100,000 tonnes.
According to an official estimate, about 280,000 fishermen in 10 provinces along the Yangtze River will be affected by the ban. Their 113,000 registered fishing boats will be grounded or destroyed. The government has allocated funds to help those affected find alternative work and provide them with welfare and retraining. To counter illegal fishing, he said river authorities would be equipped with speedboats, drones and video surveillance systems. Fishermen would also be recruited to patrol the river.

A Brand New World: Mapping the Ocean Floor

Mapping of the ocean floor may expand under an order signed by President Donald Trump on in  November, 2019 to create a federal plan to explore U.S. coastal waters. The announcement…comes amid growing international interest in charting the sea floor as unmanned aquatic drones and other new technologies promise to make the work cheaper and faster. The maps, also created by ship-towed sonar arrays, are crucial to understanding basic ocean dynamics, finding biological hot spots, and surveying mineral, oil, and gas deposits.

But much of the ocean floor remains unmapped; an international campaign called Seabed 2030 aims to map all of it in detail by 2030. Such maps cover just 40% of the 11.6 million square kilometers in the U.S. exclusive economic zone, which extends 320 kilometers from the coasts of all U.S. states and territories—an area larger than the total U.S. land mass. Today, those maps are a hodgepodge drawn from government, industry, and academic research, says Vicki Ferrini, a marine geophysicist at Columbia University’s Lamont-Doherty Earth Observatory in Palisades, New York. The federal plan, she says, could be a “game changer.”

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 Save the Rhino: Fake Rhino Horns Flood the Market

Rhinoceros horns are big business. Traditional Chinese medicine uses them to treat rheumatism and gout… And Yemeni craftsmen carve them into dagger handles. A kilogram can thus command as much as $60,000, so there is tremendous incentive for poachers to hunt the animals. Since almost all rhinoceros populations are endangered, several critically, this is a serious problem. Some conservationists therefore suggest that a way to reduce pressure on the animals might be to flood the market with fakes. This, they hope, would reduce the value of real horns and consequently the incentive to hunt rhinos.

That would require the fakes to be good. But Fritz Vollrath, a zoologist at Oxford University, reckons his skills as a forger are up to the challenge. As he writes in Scientific Reports, he and his colleagues from Fudan University, in Shanghai, have come up with a cheap and easy-to-make knock-off that is strikingly similar to the real thing.  The main ingredient of Dr Vollrath’s forged horns is horsehair. Despite their differing appearances, horses and rhinos are reasonably closely related. Horses do not have horns, of course. But, technically, neither do rhinos. Unlike the structures that adorn cattle and bison, which have cores made of bone, the “horns” of rhinoceros are composed of hairs bound tightly together by a mixture of dead cells.  Examination under a microscope showed that hairs collected from horses’ tails had similar dimensions and symmetry to those found in the horns of rhinos. 

The next task they tackled was making a suitable glue. This is made from a fibrous protein-rich glue of the sort produced naturally by spiders and silkworms. They bundled the treated horse hairs as tightly as they could in a matrix of this glue, and then left the bundles in an oven to dry.  The result was a material that, with some polishing, looked like rhino horn….DNA analysis would certainly reveal fakes, but such analysis is complicated and therefore hard to do in the sorts of back rooms in which rhino-horn sales tend to take place. The forgeries passed other tests with flying colors, though…

How to Engineer Bacteria to Search for Underground Chemical Weapons: DARPA

U.S. military researchers asked in 2019 two companies to develop new kinds of biological sensors that can detect underground disturbances or the presence of buried chemicals or weapons.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., are looking to Raytheon BBN Technologies, and Signature Science, for the BioReporters for Subterranean Surveillance program.  This project seeks to use indigenous and engineered organisms to sense changes of interest to military commanders in natural and built environments. Raytheon BBN and Signature Science won separate $1.6 million contracts for the Subterranean Surveillance progam.

The two companies will perform laboratory research and proof-of-concept demonstrations of biological sensing systems in well- controlled field tests that take advantage of recent advances in microbial science and synthetic biology to develop biological sensors, signal transducers, and reporters that can reveal subterranean phenomena at a distance.  Bio Reporters should be able to sense a phenomenon at least one meter below the surface, propagate a signal to the surface within seven days, and be continuously detectable on the surface at a distance of 10 meters over the subsequent seven days.

DARPA researchers want Raytheon BBN and Signature Science experts to take advantage of the extensive biological networks that exist underground to monitor large areas to increase the military’s ability to detect subterranean events without the need for precise coordinates.

Excerpts from John Keller, Researchers eye new biological sensors to to detect underground objects like buried chemicals and weapons, https://www.militaryaerospace.com,  Nov. 6, 2019

In more detail  Signature Science and its partner, the Texas A&M University Center for Phage Technology, aim to leverage modern and synthetic phage biology and the straightforward molecular genetics of the harmless soil bacterium Bacillus subtilis to generate a new platform to recognize and report on specific chemical threats underground. The Spore-Phage Amplified Detection (SPADe) method, potentially extensible to explosives, radiation or physical disturbance sensing, seeks to substantially advance currently used techniques which rely heavily on manual soil testing. 

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….
