Environmental Crisis/Deforestation

A new study utilizing high-resolution Sentinel-2 satellite imagery mapped 5.62 million hectares of forest fire damage across Indonesia between 2019 and 2024. The research detailed the methodology, which involved comparing pre- and post-fire satellite images, and noted that the fires were concentrated in specific regions, with climate patterns like El Niño correlating with peak fire risk.

“Using sharp, high-resolution imagery from Sentinel-2 satellites, capable of spotting details as small as 20 meters, a recent study built the first fully automated system to map burned areas across Indonesia every month in fine detail.”
CORROBORATED
Multiple web search results confirm the use of Sentinel-2 imagery to generate monthly burn-scar maps at 20-meter resolution for Indonesia. One source explicitly mentions the workflow using Sentinel-2 imagery to generate monthly burn-scar maps at 20-meter resolution.

“They also found that the fires were not evenly distributed. They were concentrated in Kalimantan, Nusa Tenggara, and Sumatra, with just six provinces accounting for 68% of the total burned area.”
SINGLE SOURCE
While multiple sources mention Kalimantan, Nusa Tenggara, and Sumatra in relation to fires, the specific quantification that these three regions accounted for exactly 68% of the total burned area, with six specific provinces, is not corroborated by multiple independent sources. The evidence only confirms concentration in these general areas.
