Data on fires in the Amazon

- 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%.

- Brazilian Amazon deforestation rates have declined from, and stayed below, their 2003 peak, despite recent increases. However, this decline was offset by a trend of increased forest degradation, according to an analysis of 23 years of satellite data. By 2014, the rate of degradation overtook deforestation, driven by increases in logging and understory burning.- During the 1992-2014 study period, 337,427 square kilometers suffered a loss of vegetation, compared to 308,311 square kilometers completely cleared, a finding that has serious implications for global greenhouse gas emissions and biodiversity loss.- Forest degradation has been connected to outbreaks of infectious diseases as a result of increased contact between humans and displaced wildlife. Degradation can also facilitate the emergence of new diseases and some experts warn that the Amazon could be the source of the next pandemic.- These findings could have major implications for Brazilian national commitments to the Paris Climate Agreement, as well as international agreements and initiatives such as the Aichi Biodiversity Targets and REDD+, which rely on forest degradation monitoring.

- In a recent announcement, Brazilian Vice President Hamilton Mourão defended the creation of a new agency that would have full authority over Amazon deforestation and fire monitoring satellite alerts. For three decades, INPE, Brazil’s civilian space agency, has held that role, making data publicly available.- The VP claims INPE satellite monitoring is outdated and doesn’t see through clouds. Critics of the government note that the space institute’s Prodes and Deter systems continue to provide excellent data on Amazon fires and deforestation, usable for enforcement, while clouds matter little in the dry season when most fires occur.- Critics contend that multiple moves by the government to disempower INPE are likely ways of denying transparency, ending INPE’s civil authority, and placing deforestation and fire monitoring satellites under secretive military control.- So far, an effort to fund new military satellites has failed. Meanwhile, Norway has partnered with the companies Planet and Airbus to offer free satellite images for monitoring tropical forests including the Amazon. Such publicly available images from Planet, NASA and other sources could thwart Bolsonaro’s possible attempt at secrecy.

- The Amazon has already seen more forest fires this year than in all of 2019, according to satellite data made available in August 2020 by a new NASA fire analysis tool.- While there are several good fire monitoring satellite systems currently at work above the Amazon, NASA’s new automated system provides near real time monitoring which could allow firefighting teams on the ground to pinpoint fires in remote areas and to take action to put fires out before they spread.- The new system also differentiates between fires in newly deforested areas, understory forest fires, grassland fires and those set by smallholders to annually clear fields. This differentiation allows authorities to zero in on large scale criminal arson committed by land grabbers, while also preventing the criminalization of subsistence farmers.- New information provided by the innovative NASA monitoring tool can count fire carbon emissions and the location and size of burnt areas, all of which could further research on global climate change, mitigation, and biodiversity impacts.

- Deforestation in the Brazilian Amazon was more than 20 percent lower for the second straight month according to data released today by Brazil’s national space research institute INPE. But forest loss in the world’s largest rainforest remains well above the average of the past decade.- INPE’s analysis of satellite data indicates that 1,359 square kilometers of forest — an area 23 times the size of Manhattan — were cleared last month, a 20.7% drop from August 2019. That follows a 26.7% drop in July.- However INPE’s deforestation data excludes forest loss from fires. More than 1,000 major fires have been registered in the region since late May. Fires in the Amazon have accelerated rapidly in recent weeks, rising to 53 major fires per day in September, up from 18 in August and 2 in July.- Despite the relative decline during the past two months, deforestation detected by INPE’s short-term alert system has amounted to 8,850 square kilometers over the past year, 10% higher than a year ago when Amazon deforestation hit the highest level since 2008.

- The number of major Amazon fires this year has more than doubled since August 13, with most of those fires being illegal. 674 major fires were detected between May 28 and September 2, with a sharp increase inside Indigenous territories in the last two weeks, raising concerns among Indigenous leaders.- Indigenous groups are being left to fight the fires on their own, without support from government institutions. IBAMA, Brazil’s environmental agency has been largely stripped of funds and lacks adequate equipment to fight the blazes, while the Army, sent to the Amazon in May, is reportedly failing to suppress most fires.- Combined with COVID-19, smoke from fires poses a serious threat to Indigenous health. Native peoples have been disproportionately affected by the pandemic, and have weaker immune systems for respiratory disease. A recent study shows that Indigenous hospitalizations for respiratory disease coincide with deforestation rates year-by-year.- Isolated Indigenous groups are especially under threat as fires put their food sources at risk. Experts say that isolated and uncontacted groups, to fend off hunger, are sighted more often roaming during Amazon fires, potentially risking exposure to Western diseases.

- Women are a driving force in the movement to protect the Amazon rainforest, the largest rainforest in the world.- Joining us on this episode of the Mongabay Newscast is environmental journalist Sarah Sax, who recently wrote about the Women Warriors of the Forest, an all-female Indigenous group that is employing new tactics and building new alliances to protect the forests they call home.- We also interview Dr. Dolors Armenteras, who is a pioneer in the use of remote sensing to monitor Amazon forests and biodiversity, and has been named one of the most influential scientists studying forest fires.- Despite her pedigree, Armenteras has faced discrimination as a woman scientist, and discusses how she is supporting the next generation of women scientists to help them overcome such biases.
