| Outline of Final Research Achievements |
Through field survey in Bungalis Island, Indonesia, we observed the peatland collapse phenomenon as tropical peatland for the first time in the world. We also confirmed that the erosion rate of the peatlands will be 160 ha per year in Riau Province. Regarding the peatland collapse phenomenon, we clarified that the control depends greatly on the control of the groundwater level and proposed a countermeasure for that.
Debris that flowed out to the sea area due to the peatland collapse revealed that part of the mangrove is formed by making sandbars on the coast and the peat is trapped in the mangrove ground and carbon is stored. Carbon stored by the newly formed mangrove was estimated to be 2500 tC / km 2 / year as a new photosynthetic component.
