Okinotorishima Island is an isolated table reef (one subtype of atoll) island located at the southern edge of Japanese territory. It is threatened as submergence by sea level rise in this century. We are developing eco-technological measures of this island by utilizing natural process of reef and island formation. The eco-technology will be applied to atoll island countries, which are also threatened by the sea level rise.

Atoll countries occupy low, narrow atoll islands and are very vulnerable to global environmental change. Tuvalu is reported to be submerged by rising sea levels at present. However, the current problems arising in atoll island countries result mainly from local problems associated with concentration of the population on the capital islands, which decreases geo-ecological resilience to future accelerating global changes.
This project will evaluate the vulnerability of Okinotorishima and atoll countries to global change as a common threat. Based on the findings, measures to manage atoll islands that are geo-ecologically resilient to future global change will be proposed and instituted with appropriate eco-technology and governance that incorporates traditional forms in the context of the globalized economy and society.
