The total area of land burned within the Brazilian Amazon saw a sharp decline in 2025, reaching its lowest level since records began in 1985. This data, provided by the monitoring initiative MapBiomas, marks a significant reduction in fire activity across the world’s largest rainforest.
The decrease represents a notable shift in environmental conditions for the region. By falling below all previous annual measurements tracked over the last four decades, the 2025 figures highlight a substantial change in the scale of fire-related land degradation compared to historical trends.
