Amazon rainforest monitoring

This micro-site aggregates data on deforestation in the Amazon from several sources. The most timely data comes from Brazil: specifically Brazil’s National Institute for Space Research (INPE) and Imazon, a Brazilian NGO.

Narrative context on these issues can be found at Mongabay’s Amazon rainforest section as well as Mongabay’s regular news reporting on the Amazon in English, Brazilian Portuguese, and Spanish. Recent headlines from these sites can be found at the bottom of this page.


This site is organized into sections:

Annual data

Annual deforestation in the legal Amazon since 1988, according to INPE's PRODES system. Note: 2023 data is preliminary.

Recent news on monitoring deforestation in the Amazon rainforest


  • Report reveals widespread use of smuggled mercury in Amazon gold mining
    on July 17, 2024 at 1:16 pm

    - Enforcement against illegal gold mines in the Brazilian Amazon ramped up in 2023, but the contamination from the mercury used in mining will likely be felt for generations to come.- According to a report from Brazilian think tank the Escolhas Institute, up to 73% of all mercury used in Brazil’s gold mines is of unknown origin; the country’s environmental agency states practically all mines in Brazil use illegal mercury.- Mercury affects primarily children, who may be born with severe disabilities and face learning difficulties for the rest of their lives.

  • Regions with highest risks to wildlife have fewest camera traps, study finds
    on July 15, 2024 at 2:46 pm

    - Camera traps are widely used to monitor biodiversity and guide conservation actions, but a first-of-its-kind study finds the technology isn’t as prevalent in highly biodiverse areas that face the most threats from human activities, such as the Congo Basin and the Amazon Rainforest.- Even in areas with a high number of camera-trap studies, nearly two-thirds were conducted outside the regions facing the highest risk of animal extinctions.- Country income, accessibility, mammal diversity and biome largely determine the locations of nearly two-thirds of camera-trap research.- Experts suggest expanding the network of camera-trap studies, building capacity among local research communities, and leveraging tools and platforms that help with data sharing and analysis to address these disparities.

  • Study to benchmark water quality finds key Amazon tributary in good shape
    on July 15, 2024 at 1:00 pm

    - Researchers have found that water quality in Brazil’s Negro River, the second-largest tributary of the Amazon, remains largely excellent, the result of a sparse human presence and strong conservation measures.- The sampling of 50 sites along the main stream of the blackwater river was carried out to develop a water quality index (WQI) for this type of Amazonian river, which hasn’t been done before.- In August, the research group will present this new WQI to the Amazonas state water resources council; if approved, the index will be used as the model for monitoring blackwater rivers in the state.- The project on the Negro is the first of the program, which aims to develop a WQI for each of the largest rivers in Amazonas state, such as the Madeira, Solimões and Purus, and establish continuous monitoring during the wet and dry seasons.

  • “Game over” for the Amazon forest and global climate if Trump wins? (commentary)
    on July 11, 2024 at 5:18 pm

    - Both global climate and the Amazon Forest are near tipping points beyond which irreversible processes would lead to unprecedented catastrophes. A second Trump presidency would both boost greenhouse gas emissions and would risk a critical delay in global efforts to avert a runaway greenhouse.- The various interrelated tipping points represent thresholds where the annual probability of a catastrophic change increases sharply, after which the risk of a disaster at some point in time increases constantly.- Climate change threatens the Amazon Forest, and if the rainforest collapses it would push global warming past a tipping point in the climate system. This risk would be greatly increased by a second Trump presidency.- This is a commentary and does not necessarily reflect the views of Mongabay.

  • After historic 2023 drought, Amazon communities brace for more in Brazil
    on July 10, 2024 at 7:32 pm

    - In the Brazilian Amazon, low river levels and insufficient rain might lead to 2024’s dry season being worse than 2023’s historic drought.- Amazonian states are already feeling early signs of the drought, although bolder actions are lacking.- Enduring water loss is an issue throughout the country, but it hits the Amazon and the Pantanal especially hard, as wildfires are breaking records.
