In 2024, the Amazon rainforest experienced its worst forest fires in over two decades, which the Copernicus Climate Change Service put down to “climate extremes and human activity”.
“The 2025 figures are significant and show that it is possible to reduce the burned area in the country,” Vera Arruda, a researcher at the Amazon Environmental Research Institute (IPAM) and co-ordinator at MapBiomas, told the BBC.
“The 31% drop compared to the historical average – driven primarily by the lowest number of fires recorded in the Amazon in 41 years – is positive news, but it does not yet allow us to conclude that this is an established trend or to scale back prevention efforts,” Arruda added.
The MapBiomas report shows a dramatic drop in area burned not just in the Amazon, but across the whole of Brazil in 2025.
Figures show around 12.7 million hectares burned in Brazil in 2025, compared to 30 million hectares in 2024.
The highest number of hectares burned in Brazil since records began was in 2007, when 30.7 million were recorded across the country.
The decline in the 2025 figures partly reflects an easing of the unprecedented fires of 2024, helped by cooler La Niña conditions instead of the warmer El Niño.
But MapBiomas warned the natural weather pattern of El Niño, which pushes up global temperatures, could extend this year’s dry season and increase the risk of forest fires.
