East Kalimantan battles 24 hotspots as fire risk rises

Indonesia has intensified its use of weather modification techniques, specifically cloud seeding, to combat ongoing forest and land fires in Kalimantan. The government's strategy includes both aerial operations and ground-based firefighting, with officials emphasizing the importance of integrating multiple approaches to manage the crisis effectively. In West Kalimantan, cloud-seeding missions took place from August 13 to 17, 2026, involving nine sorties that resulted in an estimated 10.92 million cubic meters of rainfall over targeted areas. Another planned operation is set for August 23 to 27, 2026, with coordination ongoing between the Meteorology, Climatology, and Geophysics Agency (BMKG) and other relevant bodies. In Central Kalimantan, similar operations occurred in two separate periods, July 27 to August 4 and August 11 to 15, with 13 sorties producing approximately 4.8 million cubic meters of rain. Despite these efforts, forecasts indicate that Central Kalimantan will likely remain dry until the end of August 2026, limiting the effectiveness of such interventions. The government has also increased its aerial fleet to assist in combating the fires, particularly in remote or inaccessible regions. This effort involves collaboration between the Forestry Ministry and the National Disaster Mitigation Agency (BNPB). Additional aircraft are being deployed to enhance the capacity for water-bombing operations, which are crucial in areas where ground access is limited. However, operational constraints persist due to dense smoke affecting visibility and posing risks to pilot safety. These conditions have led to delays in certain air operations, necessitating continued reliance on ground teams for critical tasks such as creating firebreaks, wetting affected areas, and safeguarding vulnerable sites. In East Kalimantan, authorities are actively addressing a growing number of hotspots, with 24 identified on a single day. The district of Paser is experiencing the highest concentration of fires, while Berau continues to see active responses from field teams. To improve situational awareness, the provincial government is analyzing historical data on land fires, noting that the current number of hotspots exceeds those recorded in August 2015. This trend underscores the severity of the situation and the need for sustained vigilance. Firefighters face logistical challenges, including poor road access, which forces them to employ portable water tanks and extend hoses up to 200 meters to suppress flames. The provincial administration is also considering proposals for weather modification to aid in extinguishing fires and replenishing water reserves near Indonesia’s new capital, Nusantara. Weather modification is viewed as a complementary tool rather than a standalone solution. Officials stress that ground-based firefighting remains the primary focus, alongside enhanced patrols, cooling operations, and preventive measures aimed at curbing the spread of fires. The integration of aerial resources is intended to bolster these efforts, particularly in hard-to-reach locations where traditional methods are less effective. While the potential benefits of cloud seeding are acknowledged, its success depends heavily on favorable atmospheric conditions, which are not always guaranteed. The unpredictable nature of wind patterns further complicates the planning and execution of such operations. The national response to the wildfires reflects a coordinated approach involving multiple agencies and levels of governance. The Forestry Ministry has been working closely with the BNPB to optimize resource allocation and ensure that all available tools are utilized efficiently. Local governments play a vital role in implementing these strategies, adapting them to meet specific regional needs. Community involvement is also encouraged, with volunteer groups contributing to firefighting efforts and supporting disaster mitigation initiatives. The scale of the challenge highlights the necessity for continuous adaptation and innovation in managing such complex environmental crises. As the government continues to monitor weather conditions and adjust its strategies accordingly, the outlook for the region remains uncertain. With the possibility of extended dry spells in Central Kalimantan and the persistent threat of new hotspots in East Kalimantan, the need for sustained intervention is clear. The combination of advanced technologies, strategic planning, and community engagement will be essential in mitigating the impact of these fires and preventing future outbreaks. The coming weeks will be critical in determining how effectively these measures can be implemented and whether they contribute meaningfully to the overall goal of restoring ecological balance and ensuring public safety.
