Data on fires in the Amazon

- The planet lost an area of tree cover larger than the United Kingdom in 2020, including more than 4.2 million hectares of primary tropical forests, according to data released today by the University of Maryland.- Tree cover loss rose in both the tropics and temperate regions, but the rate of increase in loss was greatest in primary tropical forests, led by rising deforestation and incidence of fire in the Amazon, Earth’s largest rainforest.- The data, which is now available on World Resource Institute’s Global Forest Watch, indicate that forest loss remained persistently high in the immediate aftermath of the pandemic, but “does not show obvious, systemic shifts in forest loss as a result of the COVID-19 pandemic,” according to WRI.- Destruction of primary tropical forests, the world’s most biologically diverse ecosystems, released 2.64 billion tons of carbon, an amount equivalent to the annual emissions of 570 million cars.

- The transformation of the Amazon and Atlantic rainforests into savanna-like environments will change the makeup of both the flora and the fauna of these biomes.- A study by Brazilian researchers evaluated the impacts of climate change and deforestation on more than 300 mammal species under various scenarios of savannization.- Species like primates, which depend on a dense canopy of trees to survive, could lose up to 50% of their range by the end of the 21st century.- Meanwhile, species from the Cerrado scrubland, such as the maned wolf and the giant anteater, would be able to move into degraded areas of the Amazon even as their own native range is cleared by human activity.

- Over the past twenty years the concept of “tipping points” has become more familiar to the public. Tipping points are critical thresholds at which small changes can lead to dramatic shifts in the state of the entire system.- Awareness of climate tipping points has grown in policy circles in recent years in no small part thanks to the work of climate scientist Tim Lenton, who serves as the director of the Global Systems Institute at Britain’s University of Exeter.- Lenton says the the rate at which we appear to be approaching several tipping points is now ringing alarm bells, but “most of our current generation of politicians are just not up to this leadership task”.- The pandemic however may have caused a shock to the system that could trigger what he calls “positive social tipping points” that “can accelerate the transformative change we need” provided we’re able to empower the right leaders.

- 2020 was supposed to be a make-or-break year for tropical forests. It was the year when global leaders were scheduled to come together to assess the past decade’s progress and set the climate and biodiversity agendas for the next decade. These included emissions reductions targets, government procurement policies and corporate zero-deforestation commitments, and goals to set aside protected areas and restore degraded lands.- COVID-19 upended everything: Nowhere — not even tropical rainforests — escaped the effects of the global pandemic. Conservation was particularly hard in tropical countries.- 2019’s worst trends for forests mostly continued through the pandemic including widespread forest fires, rising commodity prices, increasing repression and violence against environmental defenders, and new laws and policies in Brazil and Indonesia that undermine forest conservation.- We don’t yet have numbers on the degree to which the pandemic affected deforestation, because it generally takes several months to process that data. That being said, there are reasons to suspect that 2020’s forest loss will again be substantial.

- As Brazil continues deforesting and burning the Amazon at an alarming rate, France has announced plans to drastically reduce its dependency on Brazilian soy flour and “stop importing deforestation.”- France currently is the EU’s largest importer of Brazilian soy flour, buying 1.9 million tons annually. “Our target today is [cutting] soybean imports coming from the American continent,” said the French Minister of Agriculture and Food this week.- While the loss of its soy sales to France is of concern to Brazilian soy producers and commodities companies, agribusiness has expressed greater anxiety over whether Brazilian President Jair Bolsonaro’s continued anti-environmental rhetoric and policies will provoke a largescale international boycott of Brazilian commodities.- They especially fear the president’s hardline could risk ratification of the Mercosur trade agreement between the EU and South American nations, including Brazil. This week the EU ambassador to Brazil said that the agreement is now in standby, awaiting the country’s concrete actions to combat deforestation and Amazon fires.

- 2,500+ major blazes burned across Brazil’s Legal Amazon between late May and early November. Many were on recently deforested lands, indicative of land grabbers converting forests to pastures and croplands, while others were within conserved areas and Indigenous reserves. Of concern: 41% of burns were in standing forests.- Estimates say that nearly 5.4 million acres (2.2 million hectares) of Brazil’s Amazon standing rainforest burned this year — an area roughly the size of the country of Wales in the United Kingdom.- Brazil’s soaring deforestation rates and Amazon fires point to another problem: the nation is not on track to meet its 2020 goals under the Paris Climate Agreement for cutting greenhouse gas emissions. In fact, carbon emissions in Brazil did not fall, but rose by 9.6%, in 2019, the first year of President Jair Bolsonaro’s four-year term.- Under its UN climate commitments, Brazil is only required to measure fire-related greenhouse gas emissions from newly deforested lands, not from fires in standing forests. A questionable practice, say some critics, as fires in the Amazon are routinely set by people and escape into forests. The highest CO2 emissions from forest fires in the Amazon don’t happen during the burn, but years later, a new study concludes, complicating emission estimates.

- Brazil’s national space research institute INPE reported a third straight monthly drop in Amazon deforestation in September, but its data also showed a sharp increase in the area affect by fires.- According to INPE’s deforestation alert system, deforestation in the “legal Amazon” during the month of September amounted to 964 square kilometers, down 34% from September 2019. That follows a 27% decline in July and a 21% decline in August relative to a year ago when deforestation in the region hit the highest level since 2008.- However the reported decline in recent months does not match the trend reported by Imazon, an independent NGO, which reported increases of more than 30% in July and August, but hasn’t published September analysis yet. The discrepancy could be due to the different methodologies used by the two systems, though normally INPE and Imazon’s data show strong correlation.- Since January, INPE has reported more than 7,000 square kilometers of deforestation in the Amazon, down 10% from the same period last year, but the second highest on record since 2008.

- More than 1,000 Indigenous people volunteer as firefighters throughout Brazil, protecting 14 million hectares (35 million acres) of Indigenous lands.- However, in a year of record fires, the very continuity of the Indigenous fire brigades is at risk, with the government failing to provide the coordination, recognition, funding or support that they need.- Fire-prevention measures that were supposed to start in April, before the dry season, were instead delayed to July, once the burning had already begun, with the COVID-19 pandemic one of the factors blamed for the delay.- Insiders in the federal agencies overseeing environmental protection and Indigenous affairs also point to an official culture of neglect of Indigenous communities, which in many cases has forced Indigenous firefighters to work unpaid.

- Traditional Amazonian communities have used fire for centuries to open up small farming plots in a rotational system that allows the forest to regenerate and biodiversity to be preserved.- By contrast, the fires used to clear livestock pasture or to clear away vegetation after forest clearing tend to burn uncontrolled and permanently destroy vast swaths of the rainforest.- With the climate crisis rendering the forest drier and more flammable, villagers living alongside the Tapajós River, one of the main tributaries of the Amazon, have had increasing difficulty maintaining their traditional fire management practice.- Traditional safeguards such as creating fire breaks can help, but a project in the Brazilian state of Pará is bringing residents and researchers together to both create a fire warning and prediction system and transition away from the use of fire for farming.

- A new study has found that 40% of the Amazon is at risk of turning into savanna due to decreases in rainfall.- The paper’s authors used satellite data, climate simulations and hydrological models to better understand the dynamics of rainfall across the tropics and their impacts on the stability of tropical forest ecosystems.- The team’s simulations suggest that sustained high greenhouse gas emissions through the end of the century could shrink the minimum size of the Amazon by 66%.
