Brazil had a significant drop in the area hit by burning in the first three months of 2025. According to data from the Fire monitorplatform of Mapbiomsthe country registered 912.9 thousand hectares burned between January and Marcha reduction of 70% compared to the same period of 2024when the burnings exceeded 3 million hectares.
Most of the burned area focused on Amazon, responsible for 84% of the total, with 774.5 thousand hectares affected. The state of Roraima led the state ranking, totaling 415.7 thousand hectares burned in the quarter, followed by Pará (208,600 ha) and Maranhão (123,800 ha).
According to Felipe Martenexen, researcher of Ipam and Mapbiomas Fogo, Roraima’s highlight is explained by his distinct climate regime. “While much of Brazil lives the rainy season, Roraima faces its dry season, which makes the state more vulnerable to burning during this period”, He points out.
