Fires in Brazil's Amazon dropped to historic low in 2025

MapBiomas said 3.1 million hectares burned, the smallest area since records began in 1985, after a delayed rainy season and easing deforestation.

  • MapBiomas reported on Tuesday that forest fires in the Brazilian Amazon fell to a historic low in 2025, rebounding from the unprecedented 2024 drought. This represents the smallest area burned since records began in 1985.
  • Deforestation eased last year, reducing available fuel for fires, while communities feared a repeat of 2024's fire season. This "psychological factor" encouraged residents to control outbreaks, and a delayed rainy season blocked the "ideal window for burning."
  • Satellite images show 3.1 million hectares burned in 2025, a nationwide decline geographer Ane Alencar described as "out of the ordinary." Total burned areas in Brazil reached their smallest size since 2018.
  • The findings provide a boost for President Luiz Inacio Lula da Silva ahead of his October reelection bid, though activists remain critical of his decision to endorse a major offshore oil exploration project.
  • Alencar warned of a potential "super El Nino" in 2026, which may bring "an extended dry season and a greater risk of forest fires." Central Brazil's Cerrado savanna, meanwhile, continues burning at similar rates.
