The Smoldering Reality of Peatlands
The air in Riau does not just smell like smoke; it feels thick, like breathing through a wet wool blanket soaked in ash. Underneath the charred surface of the earth, a silent, invisible war is raging. This is not a battle fought with bullets, but with water hoses and hand tools. Beneath the moss and the dead leaves lies peat—a dense accumulation of partially decayed organic matter. When these peatlands dry out, they transform into massive stores of carbon. When they catch fire, they become 'carbon bombs.' These are not sudden explosions, but slow-burning, subterranean infernos that release gigatons of CO2 into the atmosphere, long after the visible flames have been extinguished.
Indonesia holds some of the world's largest tropical peatlands. These ecosystems act as massive sponges, soaking up water during the monsoon and releasing it slowly during the dry season. However, drainage canals, often dug for oil palm plantations or pulpwood estates, have lowered the water table. This dries out the peat, turning a resilient sponge into a volatile fuel source. Once a fire takes hold underground, it can travel for kilometers beneath the surface, invisible to satellites and local authorities, only to resurface as a new flame days later.
The Frontline Volunteers
While governments debate international climate policy and carbon credits, a group of local volunteers is wading through knee-deep mud and choking smoke. They are often young locals, former farmers, or environmental activists from NGOs. They do not have high-tech thermal imaging drones or heavy firefighting aircraft. Instead, they carry handheld water pumps, manual sprayers, and buckets. Their objective is simple yet grueling: rewet the peat. They spend their days digging small trenches to block drainage canals or pumping water into the cracked, parched earth to raise the water table. If they stop, the fire will find a new path.
The physical toll is immense. The heat is a physical weight. Working in the tropical sun, clad in basic protective gear that offers little protection against the particulate matter, these individuals face chronic respiratory issues. Many of them have seen their neighbors' homes swallowed by ground fires that seemed to come out of nowhere. They work for little pay, often relying on community donations or small grants from international environmental groups. For them, this is not an abstract debate about global warming; it is a fight to keep the air breathable for their children.
The Science of the Burn
The chemistry of a peat fire is different from a forest fire. In a typical forest fire, the fuel is the trees and leaves above ground. In a peat fire, the fuel is the ground itself. This is a slow combustion process. Because the fire occurs underground, it is incredibly difficult to extinguish. Standard firefighting techniques, such as aerial water bombing, often fail because the water never reaches the deep, smoldering layers of organic matter. The water simply runs off the surface or evaporates before it can penetrate the dense peat layers.
This phenomenon creates a feedback loop. As the peat burns, it releases carbon that has been sequestered for thousands of years. This increases atmospheric CO2 concentrations, which drives higher temperatures, which in turn leads to drier peatlands and more frequent fires. Scientists call this a positive feedback loop, where the result of a process intensifies the cause. In Indonesia, this cycle is a major contributor to the Southeast Asian haze, a phenomenon that disrupts aviation, shuts down schools, and causes massive health crises across Malaysia, Singapore, and Indonesia.
The Conflict of Interests
Why does the peat continue to dry out? The answer lies in the complex economics of land use. Large-scale agribusiness requires flat, dry land. Peatlands are naturally wet and difficult to cultivate, so drainage is the primary tool used to prepare the soil for crops like oil palm and acacia. While regulations have tightened in recent years, and some companies are now legally required to restore peatlands, enforcement is uneven. Many smallholder farmers, struggling to survive, lack the resources to manage water levels correctly, often falling victim to the same cycles of fire and regrowth.
The tension between economic development and ecological preservation is visible in every burnt stump. When a plantation expands, the surrounding peatland often becomes a buffer zone that is neglected. These buffer zones are the most vulnerable. Without active management, they become the ignition points for the next season of haze. The volunteers often find themselves fighting fires that were started by accidental sparks from clearing land or by intentional burns that quickly escaped control due to the volatile nature of the dried peat.
Tools and Tactics in the Mud
To fight a subterranean fire, one must think like a hydrologist. Modern volunteer groups are increasingly using more sophisticated methods, though they remain far from fully equipped. Some use portable sensors to detect heat signatures beneath the soil. They focus on 'canal blocking'—a technique where they build dams using local materials like plastic sheets, soil, or wood to stop water from draining away. It is a slow, manual process that requires constant maintenance, as the moving water naturally erodes these makeshift dams.
Community-based fire monitoring groups, often referred to as Masyarakat Peduli Api (MPA) in Indonesia, represent a shift toward local empowerment. These groups are trained to detect early signs of smoke and to act before a fire becomes too large to handle. They are the first responders. However, the scale of the problem often outstrips their capacity. A single small fire in a degraded peatland can expand into a massive regional disaster if the water table isn't managed proactively.
A Fragile Window of Opportunity
The window to stabilize these ecosystems is narrowing. As the climate shifts, the dry seasons are becoming longer and more intense. The peatlands that once acted as a carbon sink are increasingly becoming carbon sources. The work of the volunteers is a stopgap measure—a way to buy time for larger-scale policy changes and more robust land management strategies to take effect. They are patching a leaking dam while the water pressure continues to rise.
Every hectare of peat that is kept wet is a victory. Every fire that is smothered before it reaches the deep layers is a win for the global climate. These volunteers do not seek glory; they seek a return to a state where the ground beneath them is a sponge rather than a furnace. Their struggle highlights the reality of the modern climate fight: it is often fought in the mud, by hand, one bucket of water at a time.
