Forest Fires in Africa Feed the Amazon Rainforest

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

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

First Armed Attack on Amazon Rainforest in 30 Years

On Ju;ly 28, 2019, heavily armed gold miners invaded a remote indigenous reserve in northern Brazil and stabbed to death one of its leaders, officials say.  Residents of the village in Amapá state fled in fear and there were concerns violent clashes could erupt if they tried to reclaim the gold-rich land.  

Tensions in the Amazon region are on the rise as far-right President Jair Bolsonaro, who is against the reserves, vows to open some of them to mining.  Mr Bolsonaro says the indigenous territories are too big given the number of people living there, and critics accuse him of encouraging illegal mining and invasions of reserves.  The group of 10 to 15 heavily armed miners overran the village Yvytotõ of the Wajãpi community and “tensions were high”, according to Brazil’s indigenous rights agency, Funai. The residents fled to the Mariry village, some 40 minutes away by foot, and have been warned not to try to come into any contact with the invaders.

Based on accounts from the Wajãpi, Funai said the miners had killed 68-year-old Emyra Wajãpi, whose body was found with stab marks in a river near Mariry…”This is the first violent invasion in 30 years since the demarcation of the indigenous reserves in Amapá,” Senator Rodolfe Rodrigues told local newspaper Diário do Amapá (in Portuguese), warning of a “blood bath”…. Bolsonaro, who took office in January 2019, has promised to integrate indigenous people into the rest of the population and questioned the existence of their protected territories, which are rights guaranteed in the country’s Constitution.The president has also criticised the environmental protection agency, Ibama, and accused the national space institute, Inpe, of lying about the scale of deforestation in the Amazon.

Suing and Wining: Indigenous People, Ecuador

Hunter-gatherers in the Amazon sought in court on in April 2019 to stop Ecuador’s government auctioning their land to oil companies, as tension mounts over the future of the rainforest…The Waorani said the government did not properly consult them in 2012 over plans to auction their land to oil companies.

“We live on these lands and we want to continue to live there in harmony. We will defend them. Our fight is that our rights are respected,” said Nemonte Nenquimo, a leader of the 2,000-strong Waorani….Ecuador is pushing to open up more rainforest and develop its oil and gas reserves in the hope of improving its sluggish economy and cutting its high fiscal deficit and foreign debt…

The constitution gives the government the right to develop energy projects and extract minerals on any land, regardless of who owns it, but requires that communities are consulted first and are properly informed about any projects and their impact. Laws to regulate the consultation process have yet to be introduced – although the court case could push the government to do this, said Brian Parker, a lawyer with campaign group Amazon Frontlines, which is supporting the Waorani…

The government announced last year that it had divided swathes of forest up into blocs for auction, one of which – bloc 22 – covers the Waorani’s ancestral lands, raising the specter of pollution and an end to their way of life.  In two landmark cases in 2018, local courts sided with indigenous communities who said the government had failed to inform them before designating their land for mineral exploitation….The Inter-American Court of Human Rights also ruled in 2012 that Ecuador had violated its Sarayaku Amazonian community’s right to prior consultation before drillers started exploration on their lands in the late 1990s.

5,000 Eyes in the Sky: environmental monitoring

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

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

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

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

Biodiversity and Respect for Human Rights

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

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

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

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

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

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

100 Ways to Finance Criminal Cartels Logging Forests

The report – Green Carbon, Black Trade (2012) – by UNEP and INTERPOL focuses on illegal logging and its impacts on the lives and livelihoods of often some of the poorest people in the world set aside the environmental damage. It underlines how criminals are combining old fashioned methods such as bribes with high tech methods such as computer hacking of government web sites to obtain transportation and other permits. The report spotlights the increasingly sophisticated tactics being deployed to launder illegal logs through a web of palm oil plantations, road networks and saw mills. Indeed it clearly spells out that illegal logging is not on the decline, rather it is becoming more advanced as cartels become better organized including shifting their illegal activities in order to avoid national or local police efforts. By some estimates, 15 per cent to 30 per cent of the volume of wood traded globally has been obtained illegally…

The much heralded decline of illegal logging in the mid- 2000s in some tropical regions was widely attributed to a short-term law enforcement effort. However, long-term trends in illegal logging and trade have shown that this was temporary, and illegal logging continues. More importantly, an apparent decline in illegal logging is due to more advanced laundering operations masking criminal activities, and notnecessarily due to an overall decline in illegal logging. In many cases a tripling in the volumes of timber “originating” from plantations in the five years following the law enforcement crack-down on illegal logging has come partly from cover operations by criminals to legalize and launder illegal logging operations….

Much of the laundering of illegal timber is only possible due to large flows of funding from investors based in Asia, the EU and the US, including investments through pension funds. As funds are made available to establish plantations operations to launder illegal timber and obtain permits illegally or pass bribes, investments, collusive corruption and tax fraud combined with low risk and high demand, make it a highly profitable illegal business, with revenues up to 5–10 fold higher than legal practices for all parties involved. This also undermines subsidized alternative livelihood incentives available in several countries.

[It is important to discourage] the use of timber from these regions and introducing a rating og companies based on the likelihood of their involvement in illegal practices to discourage investors and stock markets from funding them.

How to Discover an Illegal Logger

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

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

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

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