This page collects deforestation alert data published by Brazil’s National Institute for Space Research (INPE) and Imazon, a Brazilian NGO. INPE’s system is called DETER for Sistema de Detecção do Desmatamento na Amazônia Legal em Tempo Real, while Imazon’s system is called SAD for Sistema de Alerta de Deforestation.
As explained here, month-to-month deforestation is highly variable. Short-term, alert-based deforestation detection systems do not penetrate cloud cover, so during the rainy season — from roughly November to April — estimates are notoriously unreliable when compared to the same month a year earlier. Furthermore, most forest clearing in the Amazon occurs when it is dry. So if the dry season is early, deforestation may increase earlier than normal. For these reasons, the most accurate deforestation comparisons are made year-on-year. For Brazil, the deforestation “year” ends July 31: the peak of the dry season when the largest extent of forest is typically visible via satellite.
Short-term data isn’t useless though — it can provide insights on trends, especially over longer periods of time. Generally, comparing 12 consecutive months of alert data will provide a pretty good indication of deforestation relative to other years. Therefore the charts below include monthly data as well as the 12-month moving average (Trailing Twelve Months = “TTM”).

In August 2016, the table data for the DETER columns switches from DETER to DETER-B, Brazil’s new deforestation detection system.
- ‘Indigenous women in the Amazon must be empowered’: Interview with Nemonte Nenquimo
- The new book Seremos Jaguares (We Will Be Jaguars) by Indigenous leader Nemonte Nenquimo is the memoir of a woman who fought against large oil companies to preserve her people’s land and thousands of hectares of Amazon rainforest.- The book, written with her husband and executive director of the organization Amazon Frontlines, Mitch Anderson, is a story of hope and resistance from the Amazon in the fight against climate change and the protection of nature.- In this interview, Mongabay speaks with Nemonte Nenquimo about her work to defend the Amazon and what her new book symbolizes for Indigenous women around the world.
- New conservation model calls for protecting Amazon for its archaeological riches
- Across the Amazon, archaeological remains indicate that the human presence in the rainforest is much older, larger and more widespread than previously thought.- Researchers in Brazil are lobbying to register archaeological sites as national monuments, which would confer a new layer of protection status to parts of the rainforest.- Earthen mounds known as geoglyphs, for instance, have been revealed to stretch from Acre state north into neighboring Amazonas; formally recognizing them under Brazil’s heritage law could protect this vast swath of rainforest.- “Today we know it’s highly likely that part of the forest has been changed by people,” said Dutch biologist Hans ter Steege, co-author of research that has shown there may be up to 24,000 earthworks hidden throughout the rainforest that could qualify for protection.
- EU considers postponing anti-deforestation law as pressure from agribusiness mounts
- The EU parliament and council is considering a 12-month delay to its deforestation-free products regulation, which will require exporters to prove that beef, soy, rubber and other harmful commodities aren’t sourced to deforested land.- The law was supposed to go into effect January 1, 2025, but faced mounting pressure from exporting countries and the industrial agricultural sector.- The 12-month delay could result in around 2,300 square kilometers (888 square miles) of deforestation and 49 megatons of greenhouse gas emissions, according to EU studies.
- Brazil dredges Amazon rivers to ease drought isolation, raising environmental concerns
- Brazil has committed to dredge major Amazon rivers in response to record drought that has lowered water levels and made ship passage, a key transportation lifeline, difficult or impossible.- The dredging is aimed at supporting local communities, who rely on river navigation to get supplies in from outside, and producers, who need to ship their commodities out.- But experts question whether dredging is a sustainable solution, raising concerns about long-term ecological impacts and advocating for community involvement and innovative technology for better outcomes.- The environmental risks of dredging include ecosystem disruption, increased erosion, water contamination, and harm to aquatic species such as manatees and river dolphins.
- The Amazon is ablaze again. What it means for us (commentary)
- The Amazon rainforest, devastated by over 70,000 wildfires in 2019, is once again ablaze, threatening even greater destruction of wildlife, human health, and ecosystems.- Climate change is now a tangible global threat, with rising sea levels and extreme heat affecting entire regions, while indigenous communities, like the Kogi in Colombia, have long warned of these environmental dangers, argues Mark J. Plotkin, an ethnobotanist who co-founded the Amazon Conservation Team.- The Amazon, which stores one-fifth of the world’s terrestrial carbon, plays a crucial role in regulating global climate, but continued deforestation risks releasing this carbon and disrupting weather patterns far beyond the region.- This text is a commentary and does not necessarily represent the views of Mongabay.
- Brazil’s race to approve the end of the Amazon: The BR-319 highway needs a new environmental impact assessment (commentary)
- Brazil’s race to approve “reconstruction” of Highway BR-319 (Manaus-Porto Velho) is gaining ever more momentum, with President Lula declaring his support for the project on the 10th September, a moment that could not be more ironic amid the country’s dramatic fire crisis, argues researcher Philip M. Fearnside in this commentary.- The impact of BR-319 extends far beyond the roadside strip to which the EIA and licensing discussion is limited. Planned side roads such as AM-366 would open the vast rainforest area west of the highway to the entry of deforesters, loggers and others. The rainforest in this area is also at risk of collapse from climate change, and this risk would be further increased by the deforestation and forest degradation provoked by the planned roads linked to BR-319. Loss of this forest would be catastrophic both for global climate and for water supply to other parts of Brazil, including São Paulo.- The area at risk is both the most critical and the easiest to avoid deforesting. All that needs to be done is to not build the highways that would provide access, while in other parts of Amazonia stopping deforestation requires changing the behavior of hundreds of thousands of individual actors. A new EIA is needed that includes all areas receiving impacts from BR-319 in the northern and western parts of Brazilian Amazonia. The EIA cannot be a mere bureaucratic step after which the project is automatically approved – the rational decision is to reject the project, writes Fearnside.- This text is a commentary and does not necessarily represent the views of Mongabay.
- ‘We need white men on our side to save the Amazon from destruction,’ 92-year-old Indigenous Chief Raoni says
- Indigenous leaders gathered at New York Climate Week to call on global leaders to address the unprecedented drought and wildfire crisis in the Amazon Rainforest.- Chief Raoni Metuktire, a historic Indigenous leader of Brazil, asked non-Indigenous communities to reflect on their responsibility — mainly the introduction of illegal mining, logging and cattle ranching that are accelerating the impacts of climate change.- Many Indigenous communities are in the path of wildfires, and isolated Indigenous peoples (PIA) are the most vulnerable.
- Brazil’s BR-319 highway disaster: Yet another maneuver (commentary)
- Brazil’s “reconstruction” project for the BR-319 (Manaus-Porto Velho) highway and associated side roads would open vast areas of Amazon forest to the entry of deforesters and loggers, writes Philip M. Fearnside in this commentary.- A “preliminary license” for the project that was granted in 2022 by the anti-environmental Bolsonaro presidential administration was suspended in July 2024 by judicial order but is being appealed by the highway department.- The highway department has submitted to the courts a consultant report it contracted claiming that the highway project is “environmentally viable” and the department’s press release claiming this as “proof” of viability is being touted by pro-BR-319 media and politicians.

- How the Brazilian military sabotaged protection of Indigenous people in the Amazon
- The Brazilian military has been involved in a series of controversial episodes that have undermined emergency efforts to tackle the humanitarian crisis in the Yanomami Indigenous Territory.- Reports show it failed (or sabotaged) airspace control and food deliveries to the Indigenous people, who suffer from malnutrition as a result of mercury contamination from illegal mining.- President Luiz Inácio Lula da Silva has spent millions trying to evict the illegal miners and provide care to the Yanomami, but some 7,000 miners remain in the territory, while malnutrition, malaria and other diseases continue to afflict the Yanomami.- Experts blame the military’s inaction of action against the illegal miners on a colonial ideology that was prevalent under Brazil’s former military dictatorship, and which was revived under the administration of Lula’s predecessor, Jair Bolsonaro.
