Amazon rainforest sees smallest burned area since 1985, 2025 data shows

The Brazilian Institute for Space Research’s MapBiomas project reported that the area burned in the Amazon rainforest this year was the smallest recorded since the organization began tracking fire activity in 1985. Satellite imagery showed a marked decline in hotspots across the basin, with the total burned surface falling to its lowest level in more than four decades.

Analysts attribute the downturn to a combination of higher-than-average rainfall during the typical dry season, intensified monitoring by environmental agencies, and stricter enforcement of anti‑deforestation regulations. The reduction in fire incidence follows a trend of gradual improvement after several years of record‑high burn rates, suggesting that recent policy measures and climate variations are having a measurable impact on the health of the world’s largest tropical forest.
