Indonesian fires (1997)
The Indonesian fires of 1997 were large-scale peatland and forest fires that burned across Sumatra, Kalimantan, and parts of Java, producing transboundary haze that affected Malaysia, Singapore, and parts of Thailand and the Philippines. Triggered during the 1997–98 El Niño Southern Oscillation event, the fires involved peat-draining practices, land conversion linked to firms such as Asia Pulp and Paper and plantation expansion, and contested land tenure involving actors like Caltex (Indonesia)-linked concessions and local Dayak and Melayu communities.
Land-use change connected to corporations including Kalimantan Forests Company, Sime Darby, and Journalist-documented concessions intersected with the 1997 El Niño drought, regional climate anomalies recorded by National Oceanic and Atmospheric Administration and Intergovernmental Panel on Climate Change assessments. Peatland drainage for oil palm and acacia plantations, practices promoted by financiers such as the World Bank and regional investors like Temasek Holdings and Asian Development Bank projects, lowered water tables, increasing combustibility noted by researchers from University of Reading, Leiden University, and Bogor Agricultural University. Fire use for land clearing—attributed to smallholders, corporate contractors, and transmigration projects overseen historically by transmigration policy—met with weak enforcement involving agencies like Kementerian Kehutanan and regional administrations in Riau, Central Kalimantan, and South Sumatra.
Initial hotspots were detected in early to mid-1997 amid prolonged dry conditions associated with the 1997–98 El Niño event. Satellite imagery from NASA and hotspot mapping by European Space Agency instruments showed expansion across peat domes in Riau Province, Jambi, South Sumatra, and West Kalimantan. By July–October 1997 fires coalesced into mega-fires burning millions of hectares of peat swamp forest, secondary forest, and agricultural land, with fire fronts moving toward population centers such as Palembang, Pekanbaru, and Pontianak. Transboundary haze episodes peaked in September–November 1997, causing visibility crises in Kuala Lumpur, Singapore, and disrupting aviation at airports like Soekarno–Hatta International Airport and Changi Airport.
Air quality collapsed as particulate matter and carbon monoxide levels spiked, with measurements by World Health Organization, Ministry of Health teams, and university studies reporting hazardous concentrations of PM10 and PM2.5. The fires released massive greenhouse gases, contributing to elevated atmospheric carbon traced by NASA and NOAA datasets and discussed in IPCC literature. Biodiversity loss impacted habitats for species such as the Bornean orangutan, Sumatran tiger, and migratory birds monitored by BirdLife International. Public health crises included respiratory illnesses treated in hospitals linked to networks like Indonesian Medical Association and clinics run by Médecins Sans Frontières and Red Cross societies. Peat fires produced long-burning smoldering combustion that undermined groundwater and peatland hydrology studied by researchers at Wageningen University and University of Zurich.
Economic losses affected sectors including agriculture and tourism in affected regions; plantation companies such as Sinar Mas Group faced reputational and operational disruption. Transboundary haze disrupted trade and air transport, prompting compensation debates between Indonesia and neighbors like Malaysia and Singapore. Local livelihoods for indigenous groups including the Dayak, Orang Rimba, and Melayu peoples were undermined by loss of forest resources documented by NGOs such as WWF, Greenpeace, and Friends of the Earth. Social ramifications included school closures, displacement in districts of Riau and Central Kalimantan, and legal actions involving civil society groups and litigants represented by offices aligned with Human Rights Watch and respected law faculties across Indonesia.
Domestic firefighting involved coordination between agencies including Badan Nasional Penanggulangan Bencana and provincial firefighting brigades, supported by the TNI in some operations. Techniques included back-burning, water bombing by Indonesian and regional assets, and peat rewetting trials advocated by scientists from International Union for Conservation of Nature and Wetlands International. Policy responses included moratoria on slash-and-burn cultivation, land-use planning revisions, and debates in the People's Consultative Assembly and Dewan Perwakilan Rakyat about strengthening forestry law enforcement and concession oversight. Reforms targeted peatland restoration, fire prevention units, and corporate sourcing commitments from buyers such as Unilever and Nestlé to reduce supplier-driven burning.
The haze precipitated diplomatic exchanges among foreign ministries of Indonesia, Malaysia, and Singapore, with international appeals to multilateral institutions including the Association of Southeast Asian Nations and United Nations Environment Programme. Aid from countries like Australia, United States, and Japan included aerial firefighting assistance, technical support from agencies such as United States Agency for International Development and Australian Agency for International Development, and capacity-building partnerships with universities including Australian National University and National University of Singapore. Transboundary negotiations informed later regional agreements such as the ASEAN Agreement on Transboundary Haze Pollution.
The 1997 fires catalyzed persistent policy shifts: heightened NGO campaigns by Greenpeace International and WWF-Indonesia, corporate sustainability commitments by conglomerates like Sinar Mas Group and Asia Pulp and Paper, and scientific programs on peatland hydrology at institutions including CIFOR and IRD. Long-term carbon emissions from peat degradation influenced international climate discussions at United Nations Framework Convention on Climate Change meetings and informed REDD+ mechanisms administered by UNFCCC partners. Continued challenges include enforcement against repeated burning in subsequent droughts linked to later El Niño events, ongoing restoration projects in Riau and Central Kalimantan, and community-led management initiatives supported by organizations like Wetlands International and local universities.
