Indonesia begins dry-ice trials to combat severe forest fire haze in South Sumatra

Indonesia began an experimental approach using dry ice pellets to reduce hazardous smoke over South Sumatra province on October 14, 2026. This technique, adapted from 1940s weather modification methods, is intended to combat thick haze caused by forest fires. The initial trial will target Palembang and an adjacent district. The fires are linked to prolonged dryness intensified by El Nino.

The forest fires have created dense smog that is disrupting economic activity and damaging public health in the region. The haze is affecting neighboring countries, with Singapore and Kuala Lumpur ranking among the world’s most polluted major cities.
