A study on the Restoration and Rehabilitation of Tropical Peat Swamp Forests and Reduction of CO2 Emission by Backfill Method of Mega-Rice Drainage Channel Harmonizing to Residents’ Lifestyle- Back to the Nature Project -
Restoration and Rehabilitation of Groundwater Environment in Tropical Peat Swamp Forests and Promotion of CO2 Emission Reduction
Tropical Peat Swamp Forests, Restoration and Rehabilitation of Groundwater Environment, CO2 Emission Reduction
Background, Purpose, and Project Achievements
The agricultural land development in Indonesia brought large drainage system for expansion of irrigated paddy fields, it caused the water content decreasing in surface soils and surface soil erosion and developed lands became unsuitable cultivated lands and they were abandoned. Remaining canal network accelerated the drying of the surface land dry, it is bringing heavier CO2 emission by the forest fire and the soil decomposition.
Research objectives are evaluation and proposal of useful and available technology and implementation experiments harmonizing with local industries and residents' lifestyle. New dam sites designed by civil engineering is simulated and evaluated how to bring the groundwater level recovery in this study area, it was supported by this collaborate research project with Indonesian counter partners. Field surveys were carried out for canal network structures utilized by neighbor residents and observation stations were maintained in this study area. And preliminary analysis could simulate that canal construction brought the surrounding groundwater drawdown.
Integrated hydrological model, which consists of land-surface process model, stormwater runoff and river flow model, and groundwater flow model, can estimate the water environment in tropical peat swamp forests peat. This model should be calibrated by using of some global data-set and observation data in this study field among some years. It will be used for simulation of hydrological environment and promotion of available and/or desirable water and land management in this area.
