Brazil's Amazon sees sharp decline in size of area burned in 2025
The amount of land burned in the world's largest rainforest was the smallest since MapBiomas records began in 1985.
Brazil’s Amazon recorded a sharp fall in the amount of land burned in 2025, with the area affected by fire reaching the lowest level since MapBiomas began tracking the data in 1985, according to BBC Science.
The finding points to a notable change in one of the world’s most closely watched environmental indicators. The Amazon rainforest, which spans much of northern Brazil and plays a major role in global climate regulation, has faced repeated fire damage in recent years. This latest figure suggests a much smaller burned area than in previous years, based on the long-running monitoring record cited in the report.
MapBiomas, the land-use and land-cover monitoring initiative referenced in the feed summary, has compiled annual records for four decades. Its data show that the burned area in 2025 fell to the smallest level in that period, marking a significant decline compared with past fire seasons. The feed does not provide the exact size of the area burned, but it does state that this was the lowest level since records began.
The reduction is important because fire in the Amazon can be linked to both environmental stress and human activity, and large burn events can have lasting effects on forests, wildlife and local communities. A smaller burned footprint may ease some immediate pressure on the region, though the feed summary does not give further detail on the causes of the decline or whether the trend is expected to continue.
This article is based on a monitored public feed and the information provided in the BBC Science report summary. Novexa News has not independently verified the underlying MapBiomas dataset, but is reporting the figures as described in the source feed.
