Biogeochemical forest model for evaluation of ecosystem services (BGC-ES) and its application in the Ise Bay basin

Forest ecosystem services (ES), including water resources, carbon sequestration, nitrogen absorption, timber production, and sediment production in the Ise Bay basin, were estimated using a process-based biogeochemical forest model (the BGC-ES model and the RUSLE). This model was proposed and studied in the Yahagi river basin by some of the authors. To evaluate the ES on a 5-km-mesh scale, simulations from 1960 to 2040 were carried out under the following scenarios: an artificial forest under standard management (FM) and under forest management abounded from 1990 (AFM). Forest management practices strongly affected carbon sequestration and timber volume compared to other ES related to forest area.
