This article will analyze an ecological change and agrarian transformation in peatland area in Central Kalimantan, Indonesia. Conceptions of dispossession of local people and a Marxist ecologist’s metabolic rift will be modified to observe these phenomena of socio-ecological changes. Historically, different capital circuits ranging from coconut, rubber, staple, wood, palm oil have been expanded into the peatland area and each circuit creates a rift in social metabolism. The recent commodity in peatland is carbon by which the only concession for credits market resides in Central Kalimantan as both using Verified Carbon Standard and Climate, Community and Biodiversity Standard. As the concession creates several scenarios of forest deforestation in calculating carbon offset, it encloses lands from local people in the prevention of peatland encroachment. Simultaneously, the concession commodifies the social reproduction of the community through calculating the welfare scenario and its intervention. The carbon trading project then becomes the penultimate process of farmer dispossession that describes at once the occurrence of a deepening of metabolic rift.
