Student participation in an action research event in Southern Okinawa, Ryukyu Islands.

People in tropical-subtropical small islands have lived with limited environmental resources. Recent increases in island populations, tourism, and changes in land-use and social structure have modified water and other environmental resources, thereby affecting coastal ecosystems (e.g., coral reef system). Small islands are also vulnerable to global climate change. For sustainable development on islands, our project aims to investigate multiresource adaptive governance based on land-sea linkage of water cycle in coral reef island system.
