In the face of a devastating wildfire season, Indonesia is taking a unique approach to combat the flames: cloud seeding. This controversial method, rarely employed globally, has become a focal point in the country's battle against the blazes.
The Burning Issue
Indonesia's Borneo, a region renowned for its pristine rainforests and unique wildlife, is under threat. With a strong El Nino driving the fires, experts predict this season could be one of the worst in recent memory. The government reports over 100,000 hectares burned in the first half of the year, while independent sources estimate the figure to be significantly higher.
Cloud Seeding: A Desperate Measure?
Cloud seeding, a technique involving the introduction of substances like silver iodide into clouds to induce precipitation, is being touted as a potential solution. Indonesia is ramping up its efforts, with a history of severe fires during previous El Nino events. Meteorologist Safillah Anggie Wahyuni, who has dedicated herself to this cause, explains that weather modification optimizes existing cloud potential rather than creating new ones.
However, the technique is not without its critics. Experts question its effectiveness during the dry season when wildfires are at their peak. Research suggests that the efficacy of cloud seeding is difficult to assess, and concerns have been raised about the potential harms of widespread silver iodide use and the associated costs.
A Temporary Fix?
Despite these concerns, Indonesia's weather agency, BMKG, acknowledges that cloud seeding is a mitigation effort rather than a permanent solution. Research conducted by BMKG suggests that cloud seeding can be effective, with a 12-day operation in 2023 reportedly doubling rainfall and eliminating fire hotspots.
However, activists argue that such mitigation efforts fail to address the underlying issues, including the mass conversion of rainforests and peatlands. Uli Arta Siagian, a local environmental advocate, emphasizes the importance of protecting these vulnerable ecosystems from development.
Regional Impact
Indonesia's wildfires have a far-reaching impact, with the resulting haze affecting neighboring countries like Malaysia and Singapore. In recent days, air pollution levels have spiked in the Malaysian part of Borneo, leading to school closures. In addition to cloud seeding, Indonesia is implementing other measures such as peatland rewetting and satellite monitoring of fire hotspots.
A Complex Battle
This year's fires are further exacerbated by a powerful El Nino, a natural climate phenomenon that brings global changes in weather patterns. The area burned in the first half of 2026 already exceeds the total loss of 2023, when El Nino last formed. Activist groups warn that climate change is intensifying this trend, with El Nino arriving on top of higher global temperatures, triggering more extreme weather.
Conclusion
As Indonesia grapples with this environmental crisis, the use of cloud seeding highlights the complex challenges and trade-offs involved in tackling wildfires. While it may provide temporary relief, a more comprehensive approach addressing the root causes is essential for long-term sustainability.
