Applegate et al 2012: The Impact of Drainage and Degradation on Tropical Peatland Hydrology, and Its Implications for Effective
Theme IX. Tropical peatlands
Clearing and draining tropical Peat Swamp Forests lowers water tables and causes rapid subsidence of the peat surface through the processes of oxidation, compaction and consolidation. These processes have a profound effect on peatland topography and hydrology. Water levels are lowest, and therefore subsidence rates highest near canals, resulting in a distinctive ‘mini dome’ landscape. This is the situation in large parts of Central Kalimantan, Indonesia, where the Kalimantan Forests and Climate Partnership (KFCP) is undertaking a REDD+ demonstration initiative. Part of the activities of the KFCP involve peatland rehabilitation, focusing on ‘canal blocking’ rather than just dam construction, through a consultative process involving Village Agreements with local communities which aim to maximize community inputs and improving their livelihoods.
