Brazil Sees 58% Drop in Burned Areas in 2025 Following Historic Wildfires
Brazil's burned area dropped 58% in 2025 from 2024, with significant biome-specific impacts and reduction attributed to climate and policy measures.
- • Brazil saw a 58% reduction in burned area in 2025 compared to 2024, totaling 127,000 km².
- • The Amazon had its lowest fire incidence since 1985, with 31,400 km² burned.
- • The cerrado accounted for 69% of the burned area, with the pantanal most affected proportionally.
- • Fire reduction attributed to climate factors, reduced deforestation, and stricter fire control enforcement.
Key details
In 2025, Brazil experienced a significant 58% reduction in areas affected by fire compared to the previous year, with burned regions totaling 127,000 square kilometers. This decline follows the historic wildfires of 2024, when fires devastated approximately 302,000 square kilometers amid prolonged drought and irregular burning conditions.
The Amazon biome registered its lowest fire incidence since 1985, with 31,400 square kilometers burned in 2025 — a sharp decrease from 158,200 square kilometers in 2024. Despite this overall improvement, the cerrado remained the biome most impacted by fire, accounting for 69% of the burned area, while the Amazon contributed 25%. The pantanal biome, although burned in smaller absolute terms, was proportionally the most affected, with 69% of its area burned.
Experts attribute these improvements to a combination of factors. Ane Alencar, director of science at the Amazon Research Institute (Ipam), highlighted several influences, such as a delayed rainy season, decreased deforestation rates reducing ignition sources, and stricter fire control protocols implemented after the 2024 fire season. Enforcement actions and pressure from the Supreme Federal Court also played a crucial role in reducing fire incidents.
Distinct fire dynamics were noted across biomes, with the Amazon naturally less adapted to fire and the cerrado evolving with natural fire regimes. However, human activity has altered fire patterns, especially in the cerrado, where human-induced ignition has changed traditional behaviors. Specialists warned that severe droughts and climate phenomena such as El Niño remain significant risks, emphasizing the need for preparedness to avoid repeating past levels of widespread burning.
Adding historical context, data indicate that nearly half of Brazil’s total burned areas since 1985 are concentrated in three states: Mato Grosso, Pará, and Maranhão. Mato Grosso alone accounts for 45.1 million hectares burned, Pará 31.6 million hectares, and Maranhão 20.7 million hectares.
Overall, while the 2025 data mark a substantial improvement in fire management and prevention in Brazil, experts caution that ongoing vigilance and environmental policies remain essential to sustaining these gains amid climate variability and natural biome vulnerabilities.
