12. Mineral Soil Peat: Organic matter accumulated over thousands of years, storing concentrated carbon in thick layers Peat dome What are peatlands? River River < 1m > 3m Tropical peat swamp forest Organic carbon The peat bog is rain water fed
22. Conversion SE Asian peat forest areas A total of about 13 million ha of SE Asian peat swamps have been drained for agriculture and plantations
23. On the issue of continued emissions Conversion of peatswamp rainforest to oil palm plantation carbon store (t C ha -1 ) years after conversion 0 500 1000 1500 2000 2500 0 10 20 30 40 50 loss: > 430 tC/ha loss: > 130 tC/ha

This picture shows the location of a peat dome in the flood plain in between two lowland rivers. A substantial part of the peat dome is located above river water surface. These forms of peatlands are called bogs, they are oligotrophic (poor in nutrients) and rain water fed. The peat lies like a gigantic drop a water on the lowland plain, held together by the dead organic material and protected by a blanket of living forest that maintains a humid micro-climate and prevents direct solar impact.
First click: Some relatively minor emissions are derived from peatlands in arctic and sub-arctic zones Second click: More substantial emissions are derived from peatlands in the temperate zones and tropical zones of the Americas Third click: The most substantial emissions, covering over 70% of global peat-based emissions are from SE Asia.
