Project
This research project, funded by the Japanese government's “Environment Research and Technology Development Fund”, aims to identify adaptation measures to enhance the resilience and sustainability of coastal communities in Pacific atoll nations vulnerable to climate change. The project employs an interdisciplinary approach, bringing together experts from the natural sciences, social sciences, and engineering. Its greatest academic significance lies in its integration of previously separate topics—such as coral reef ecosystem conservation and restoration, coastal disaster prevention engineering, building local community resilience, and international environmental cooperation—to provide a systematic, crosssectional approach spanning scientific findings to practical implementation. The project is scheduled to run for three years, beginning in 2024. The Environmental Restoration and Conservation Agency (ERCA) is responsible for project and funding management.
About us
We are a team of researchers from a wide range of fields, including natural sciences, social sciences, and engineering, working to ensure the resilience and sustainability of coastal communities in small island nations in the Pacific region. Our research team is comprised of researchers from universities, research institutes, and private companies in Japan. We strive to improve our research results by interacting not only with our own members but also with people in related fields internationally. If you are interested in this research project, we welcome your collaboration.
