Indonesia's "Rain Doctors" Fight Wildfires
27 Aug
Summary
- Indonesia is using cloud seeding to combat wildfires on Borneo island.
- Over 100,000 hectares have burned, with El Niño intensifying fire danger.
- This tactic involves releasing particles to boost rainfall in specific conditions.

Indonesian authorities are deploying cloud seeding operations in an effort to curb the spread of wildfires devastating Borneo. The initiative aims to induce rainfall by releasing particles like silver iodide and salt into the atmosphere, optimizing existing clouds for precipitation over peatlands. This emergency measure is being implemented as over 100,000 hectares have already burned, with an intensifying El Niño increasing fire risks.
This tactic, while not universally applied for wildfire suppression, represents an expansion of Indonesia's efforts since the severe fires of 2015. Experts note that weather modification is effective only under specific atmospheric conditions and does not create clouds themselves. While nearly 50,000 firefighters are on the ground, cloud seeding is considered a targeted emergency response to moisten vulnerable areas and suppress active blazes.
Activists emphasize that while cloud seeding offers temporary relief, it does not address the root causes of the fires, such as deforestation and peatland conversion. Preventing future infernos requires a focus on landscape protection and restoration. Officials acknowledge cloud seeding as a mitigation effort, not a permanent solution to the ongoing crisis.
