Problem
We are committed to restore degraded tropical forest and wetland ecosystems. In Central Kalimantan, tens of thousands of people have been affected by fires in recent years. These repeated fires dry out the land, reduce biodiversity and slowly rob the lnad of its ability to support crops. Rich peatlands have seen more severe land degradation due to logging, forest fires, land clearance and peat drainage recently. As the peatlands gets drained and dry, it becomes extremely vulnerable to fires, and they start to release large amount of carbon dioxide and other greenhouse gases. The only permanent and sustainable way of preventing it is to raise water levels and find ways to use the land while it remains wet.
Solution
Peat compaction dams restores the natural hydrological cycle in fire-prone wetlands, reduce fire risks, and regenerate the forest canopy bringing life back to vital ecosystems.
Performance and impacts
By late 2021, project engineering teams had constructed more than 200 peatland compaction dams, which have had a dramatic effect. Project peatland areas are now inundated with water, which enables the habitat to effectively regenerate on its own while significantly reducing the risk of fire.
