Indonesia’s government announced a trial deployment of dry ice over South Sumatra on Thursday as part of efforts to mitigate widespread wildfires and the hazardous smoke they generate. The coordinating security minister stated the initiative operates under presidential directive and indicated potential expansion to other regions if results prove satisfactory. The measure represents an escalation in response strategies following earlier attempts involving cloud seeding, water bombing, and military personnel deployment.
Since January, approximately 900,000 hectares have burned across Indonesia during what officials characterize as the worst fire season in more than a decade. Contributing factors include an exceptionally strong El Niño weather pattern and persistent slash-and-burn agricultural practices aimed at clearing land for crop cultivation. The resulting smoke has blanketed millions of Indonesian residents for extended periods, generating mounting criticism of governmental response efforts. A class action lawsuit was filed accusing authorities of negligence, while tens of thousands sought medical treatment for respiratory conditions related to smoke exposure.
Air quality degradation has extended beyond Indonesia’s borders, affecting neighboring Singapore, Malaysia, the Philippines, and Timor-Leste. Singapore recently implemented medical subsidies for haze-related treatment and distributed N95 masks to eligible populations, measures last employed in 2015. Both Singapore and Kuala Lumpur ranked among the world’s most polluted cities during the preceding week. Timor-Leste announced school closures and advised residents on protective measures.
Experts express skepticism regarding dry ice effectiveness as a comprehensive solution. A bushfire research specialist noted the approach might provide localized, temporary relief given prevailing weather patterns moving smoke eastward to westward. The technique, involving dispersal of solid carbon dioxide to promote cloud ice formation, originated in the 1940s but faces limitations in addressing systemic fire management challenges. Peatland fires prove particularly difficult to combat, capable of burning underground for extended periods.
President Prabowo Subianto directed intensification of firefighting efforts and investigations into suspected fire starters. Researchers cautioned that escalating climate change could transform the issue from a regional challenge into a global concern requiring coordinated international approaches.
