Peatland ecosystems in Southeast Asia are globally important as carbon sinks, rich in terrestrial and aquatic fauna and flora, and important sources of livelihood for local communities. However, agribusiness-driven land-use change and drainage cause peatland degradation and peat fires, which generate "haze" air pollution and lead to significant economic losses and health impacts. Disturbed peatlands also become substantial sources of greenhouse gas (GHG) emissions.
