Volunteers Battle Peat Fires in Borneo to Halt Massive Carbon Emissions

In the remote peatlands of Indonesia's Borneo island, a group of volunteers is confronting a hidden climate threat by manually extinguishing fires that could release centuries of stored carbon into the atmosphere.

The fires, which burn beneath a layer of water‑logged peat, are not ordinary forest blazes. When peat ignites, it can smolder underground for weeks, emitting large quantities of carbon dioxide and methane that scientists liken to "carbon bombs" because of the sudden, massive release of greenhouse gases.

Local residents, many of whom have lived alongside the peat swamps for generations, have taken it upon themselves to dig firebreaks, transport water, and use hand‑held tools to smother flames that are otherwise difficult for conventional firefighting equipment to reach. Their efforts are fraught with danger: the ground can collapse without warning, and the thick smoke poses immediate health risks.

These peat fires have broader regional consequences. The haze generated by the burning peat travels across national borders, contributing to a persistent toxic smog that blankets parts of Southeast Asia each dry season. Air quality monitors in neighboring countries routinely record particulate matter levels far above World Health Organization guidelines, prompting public health advisories and school closures.

Experts warn that the carbon released from peat fires could offset years of emissions reductions achieved elsewhere. Unlike tree biomass, peat stores carbon that accumulated over millennia; once ignited, that ancient carbon is rapidly returned to the atmosphere. The International Union for Conservation of Nature estimates that peatland fires in Indonesia account for a significant share of the country's total greenhouse‑gas emissions during peak fire periods.

Government agencies have stepped in to provide limited support, such as supplying water tankers and coordinating aerial surveillance. However, the sheer scale of the peatland network—spanning hundreds of thousands of hectares—means that official resources are stretched thin, leaving volunteers as a critical frontline defense.

Environmental NGOs highlight that addressing the root causes of peat ignition—namely, illegal land clearing, drainage for agriculture, and climate‑driven drought—will be essential to curbing future outbreaks. Rewetting projects, stricter enforcement of land‑use regulations, and community‑based monitoring are among the strategies being promoted.

As the dry season wanes, the volunteers continue their labor‑intensive work, hoping to contain the blazes before they breach larger forested areas. Their persistence underscores a growing recognition that local action, even when undertaken by non‑professional responders, can play a pivotal role in mitigating climate impacts and protecting public health across the region.
