The Pacific Islands Climate Adaptation Science Center (PI-CASC) is a collaborative partnership between the US Geological Survey and a university consortium hosted by the University of Hawaiʻi at Mānoa, with the University of Hawaiʻi at Hilo and the University of Guam, designed to support sustainability and climate adaptation in communities across the Pacific Islands.


Our goal is to provide natural resource managers and cultural stewards in federal, state, and local arenas access to the best science available on climate change and other stressors impacting the region’s natural and cultural resources. Emphasizing cooperative efforts between researchers and managers, we aim to create actionable science and accessible products to use on real problems.


PI-CASC research generates actionable climate science within several key focus areas defined by regional stakeholder needs.


PI-CASC strives to turn research results into usable products, providing resource managers the tools to address climate impacts.


PI-CASC programs focus efforts on topics like co-production, student and regional capacity building, and stakeholder networking.


The Pacific Islands region is among the first to experience climate shifts and witness their socio-ecological effects. To adapt, we aim to understand these climate change impacts and identify effective adaptation strategies using cutting-edge research, regular dialogue with stakeholders and community members, and sharing of new and available online resources.
