Pacific Islands

The Pacific Islands Climate Adaptation Science Center (PI-CASC) spans the Pacific Basin from the Hawaiian Island archipelago to the US-affiliated islands of the South Pacific. The CASC focuses their efforts on developing science on drought, coastal adaptation and planning, forest conservation, and climate adaptation in low islands and atolls.

Using High-Resolution Imagery and Artificial Intelligence to Support Climate Change Resilience in Agroforestry Across the Pacific

On remote Pacific islands and outer atolls, agroforestry (i.e., the cultivation and conservation of trees for agriculture) provides food security and income to local communities. Growing instability from climate change and invasive species like the coconut rhinoceros beetle threaten these resources. Actively managing and sustaining agroforestry resources requires detailed and up-to-date knowledge

Using Oral Histories of Marshallese and Yapese Voyagers to Support the Development of Community Engagement for Sustainable Sea Transport

There is a growing movement in the Pacific to decarbonize sea transportation. The transition to sustainable sea transport is projected to reduce socioeconomic vulnerability to external rises in oil prices while lowering carbon emissions in a period of intensifying climate change. With potential periodic global breakdowns in transport of fuel due to potential hazards such as global pandemics or pol

Partnering with Indigenous Communities in the Pacific Islands

For millennia, Indigenous Pacific Islanders have stewarded natural resources to sustain their communities, traditional ways of life, and cultural identities. This close relationship with the natural world puts these communities at the forefront of climate change impacts. Drawing upon a strong history of adaptation and innovation, Indigenous communities are key collaborators on adaptation work...

A Prioritization Plan for Coastal Wetland Restoration on Moloka‘i

Moloka‘i has great wetland restoration potential in Hawaiʻi, but most remaining sites are highly degraded. The future of several endangered waterbirds and insects relies on restoring coastal wetland habitat that is resilient under sea-level rise and coastal flooding. Currently, managers lack background data on Molokaʻi to prioritize sites for restoration. In this project, Researchers will develop

Building Capacity for Actionable and Interdisciplinary Science Across the Climate Adaptation Science Center Network

Actionable science has evolved rapidly over the last decade, and the Climate Adaptation Science Center (CASC) network has established itself as a leader in the field. The practice of actionable science is generally described as user-focused, action-oriented science that addresses pressing real-world climate adaptation challenges. It is also sometimes referred to as usable science, translational ec

Coral Response to Land-to-Ocean Freshwater Flux: A Ridge-to-Reef Perspective

Assessments that incorporate areas from land-to-ocean, or “ridge-to-reef", are critical to examine how land-use practices are altering stream discharge and nearshore marine health and productivity. Stream systems in both Alaska and Hawaiʻi are expected to experience changes in water quality associated with changing environmental conditions and increased human-use.

Developing the American Samoa Climate and GIS Data Portal: A Collaborative Approach to Enhancing Data Availability and Adaptation Capacity

The territory of American Samoa is highly vulnerable to the negative effects of climate change and there are many local agencies working towards adapting to this problem. These efforts often require organization, interpretation, or presentation of large amounts of data and information. However, those who directly need these data often do not have the time or experience to synthesize them in a form

Ecological and Socio-Cultural Responses to Transplanting Corals to Enhance Reef Resilience Near Oʻahu

Coral reefs are declining worldwide due to a combination of stressors, but climate induced ocean warming is the biggest threat. Warming oceans lead to ‘coral bleaching’ and frequent death, compromising the structure and function of reefs. The increasing frequency and severity of bleaching means that human intervention is needed to support the adaptive capacity of reefs. Most proposed interventions

Effect of Extreme Tidal Events on Future Sea-Level Rise Scenarios for He‘eia Fish Communities undergoing Ahupua‘a Restoration

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas.

Field Surveys for Vanishing Species: Closing Data Gaps to Understand Climate Change Impacts on Hawaiian Land Snails and Preserve Biodiversity

The Hawaiian Islands have an extremely diverse number of plants and animals found nowhere else on Earth. Changes brought about by the arrival of humans and the introduction of non-native predators, weeds, and diseases has led to the extinction of hundreds of Hawaiian species – far more than any other U.S. state.
