Wildfires scorched more than 1.9 million hectares across Indonesia between January and September 2026, driven by land-clearing practices and dry weather.
The Indonesia Meteorology, Climatology, and Geophysical Agency attributed reduced rainfall to strong El Niño intensity and the Indian Ocean Dipole.
The Centre for Research on Energy and Clean Air estimated that air pollution-related deaths reached 5,310 in September, with 58 million people exposed to hazardous air.
