Overview
【Urbanization in Indonesian Watersheds Research】
This study aims to elucidate the diversity of qualitative risks (pollution and salinization) to groundwater resources in coastal cities, where such resources are highly developed.
Specifically, it evaluates the diversity of groundwater vulnerability in coastal cities.
【Agricultural Watershed Environmental Innovation Research】
This study aims to propose watershed-based agricultural innovation that achieves mutual conservation of agriculture and coastal environments—specifically, an optimal watershed water, nutrient, and sediment reuse system—and to construct a community system for its effective operation, thereby promoting its widespread adoption in agricultural regions.
