As a low-lying coastal nation, the Republic of the Marshall Islands is at the forefront of exposure to climate change impacts. The Republic of the Marshall Islands has a strong dependence on natural resources and biodiversity not only for food and income but also for culture and livelihood. However, these resources are threatened by rising sea levels and associated coastal hazards (storm surges, saltwater intrusion, erosion, etc.). High-quality data for atoll ‘ridge to reef’ (land and ocean) areas are needed to provide remote communities with the tools and strategies to make adaptation efforts before disasters occur. Although the Republic of the Marshall Islands’ National Strategic Plans recognize the need to...

American Samoa is vulnerable to sea-level rise in part due to the steep terrain of its islands. This terrain requires the majority of the islands’ villages and infrastructure to be located along thin strips of coastal land. The situation is worsened by the recently recognized rapid sinking of the islands, which was triggered by the 2009 Samoa earthquake and is predicted to last for decades. This subsidence is estimated to lead to roughly twice as much sea-level rise by 2060 as what is already predicted from climate change alone. As a result, the timeline of coastal impacts in American Samoa will be decades ahead of similar island communities in the Pacific. Despite this urgency, decision-makers in the region lack...

The Hawai‘i Drought Knowledge Exchange project has been successfully piloting three sets of formal collaborative knowledge exchanges between researchers and managers to co-produce customized, site specific drought data products to meet the needs of their partners. Through these pilots, knowledge co-production has demonstrated how active collaboration between researchers and managers in the design and production of data products can lead to more useful and accessible applications for drought planning and management. Resource managers have strongly embraced the need for better and more timely information on climate change, variability and drought, as these stressors exert a large and costly impact on resources...

Hawaiʻi and the United States Affiliated Pacific Islands face unique challenges in adapting to climate change due to geographic isolation, coastal hazards, close cultural and economic links natural resources, and underserved populations. To address these problems, the PI-CASC works to develop actionable research products through collaborative engagement with cultural and natural resource manager to ensure applicability of the research. In efforts to further support these co-production processes, the PI-CASC Management Climate Corps was developed to connect local natural resource managers, researchers, cultural practitioners, policy professionals, community leaders, and graduate students on Hawaiʻi Islands. The...

Hawai‘i’s isolation, paired with limited water resources, make the archipelago sensitive to reductions in water availability. Drought can take different forms, varying across Island geographies with respect to frequency, intensity, duration, and extent. A drought event can exert hydrological, agricultural, ecological, and socio-economic impacts – and these impacts have been growing over the past century as droughts have become more frequent and severe. While the impacts of drought in Hawai‘i have been recently documented, important gaps remain in understanding these dynamics when engaging with multiple other stressors such as invasive species, shifting fire and climate patterns, pests, and pathogens. In particular,...

Detailed, reliable projections of future changes in climate are needed by Hawai‘i’s resource managers, such as water utilities managers, land managers, conservation organizations, and decision makers. However, global climate models (or “general circulation models”), which are currently the most commonly used tool for projecting future climate variations, are known for representing large-scale climate patterns and are not ideal for simulating climate processes at small spatial scales, such as those relevant to Hawai’i’s climate. Traditionally, the technique of “downscaling” is used to bridge this gap between global climate models and local climate conditions. Due to the lack of downscaled datasets for Hawai’i, however,...

Coral reef ecosystems serve as natural coastal defenses, support local island economies, and are important sources of food for coastal communities. However, an increase in coral bleaching events, and the associated declines of coral cover and diversity, are highly likely as sea surface temperatures continue to rise. Multiple coral bleaching events between 2013 and 2017 have already impacted the reefs of Guam and the Commonwealth of the Northern Mariana Islands, resulting in the loss of more than a third of shallow living-coral cover, with some species groups experiencing greater than 90% mortality. This devastating series of bleaching events strengthened existing partnerships between federal and local agencies and...

Globally, shorelines provide a vital defense system against extreme weather and erosion events and are a critical public and cultural resource. Within the state of Hawaiʻi, coastal vulnerability and historic change has been well documented and studied on the Islands of Oʻahu, Maui, and Kauaʻi, but this has not been done for the Island of Hawaiʻi, the largest and most diverse island in the Hawaiian archipelago. For example, Hurricane Lane caused major flooding and coastal erosion on Hawaiʻi Island in 2018, but no comprehensive baseline shoreline dataset exists to document and quantify the changes it caused. To help fill this knowledge gap, this study aims to create a shoreline inventory of the entire coastline...

The Republic of Palau, a Freely Associated State of the U.S. and a global leader in ocean conservation, recently implemented the Palau National Marine Sanctuary, which closed 80% of its ocean to fishing. As offshore fish become scarcer in the domestic market, managers have begun to worry about increased harvesting pressure on already overfished nearshore environments. This pressure, in addition to stressors from land-use change, sea-level rise, and warming oceans, could threaten the food and economic security of many Palauans. However, adaptively managing stressors in an integrated way can mitigate declines and even promote recovery, while still being cost-effective, resulting in direct benefits to coastal communities....
