The East-West Center’s Pacific Regional Integrated Sciences and Assessments (Pacific RISA) program helps communities in Hawai‘i and the US-Affiliated Pacific Islands adapt to a changing climate.

Pacific RISA’s work is conducted through interdisciplinary research and partnerships with local, national, and regional stakeholders. As one of 11 RISA programs sponsored by the US National Oceanographic and Atmospheric Administration (NOAA), Pacific RISA emphasizes the engagement of communities, governments, and businesses in developing effective policies to build resilience in key sectors such as water-resource management, coastal and marine resources, fisheries, agriculture, tourism, disaster management, and public health.

Established with partial support in 2003 and full NOAA funding in 2010, the Pacific RISA program supports communities and research in Hawai‘i, American Sāmoa, Guam, the Commonwealth of the Northern Mariana Islands, the Republic of Palau, the Federated States of Micronesia, and the Republic of the Marshall Islands.

Objectives of the Pacific RISA program are as follows:

  • Meet critical climate information needs in the Pacific Region through multidisciplinary climate research, assessment, education, and training
  • Provide integrated, locally relevant climate information to decision-makers and communities in the Pacific Region
  • Enhance regional and local capabilities to manage climate risks, build resilience in key sectors, and support sustainable development
  • Promote collaboration among Pacific regional, US national, and international institutions and programs providing climate information products and services

Present projects focus on several themes:

  • Assessing the impacts of predicted climate variability and change throughout Hawai‘i and the US-Affiliated Pacific Islands
  • Linking and communicating mid-range projections with end-of-century downscaled projections
  • Conducting stakeholder-inclusive, place-based science to establish sector-relevant decision thresholds
  • Helping decision-makers assign different kinds of value to resources across sectors and islands and choose adaptation strategies

Recent Activities

The Pacific RISA team led writing of the chapter on Hawai‘i and the US-Affiliated Pacific Islands in Volume II of the Fourth National Climate Assessment. Released in November 2018, this is the most significant US report to assess the effects of climate change on the US economy and communities. Strained freshwater supplies, damaged and compromised coastal infrastructure, coral reef death, and greater stresses on native biodiversity and species are major concerns and challenges detailed in the Hawai‘i-Pacific Islands chapter of the report.

Through the collaborative Pacific Islands Regional Climate Assessment and the sustained US National Climate Assessment process, Pacific RISA is developing jurisdictional-level climate science summaries in 2019-2020. Working in close collaboration with regional partners, Sustained Climate Assessment Specialist Zena Grecni and East-West Center Fellows Victoria Keener and Wendy Miles have been holding workshops in the US Affiliated Pacific Islands to gather input from sectoral experts on how climate variability and change is affecting local communities, ecosystems, fisheries, health, agriculture, disaster management, infrastructure planning, cultural resources, tourism, and the economy.

Recent activities in Hawai‘i include creating experimental seasonal climate projections and an assessment of the effects of future climate change on the quantity and economic value of freshwater resources on Maui and Oahu. In American Sāmoa, researchers have been working with the power authority and local students at the community college to monitor water quality and plan for future climate impacts. In the Republic of the Marshall Islands, Pacific RISA is evaluating the impact of climate change on human migration.

In 2020, East-West Center Fellow Laura Brewington worked closely with the Republic of the Marshall Islands to organize the nation’s first Climate Change and Health Dialog. Dr. Brewington is the Lead PI on NOAA’s International Research and Applications Project for work on “Climate, Health, and Migration in Pacific Islands.” This project serves migrant communities from the Republic of the Marshall Islands and inform health professionals, policymakers, and community organizations in sending and receiving locations about the climate-related health risks that migrants may be experiencing now or may face in the future.

Fellow Victoria Keener serves on the City and County of Honolulu Climate Change Commission, participating in monthly meetings and working groups. In July 2018, Honolulu Mayor Caldwell issued a citywide directive on climate change and sea-level rise based on a report from the Commission that included nine policy recommendations.

Dr. Brewington continues to serve on the Pacific Invasives Partnership, which promotes coordinated planning and assistance from regional and international agencies to meet the invasive species management needs of the countries and territories of the Pacific. In 2018, Dr. Brewington co-convened the Partnership’s annual meeting in New Zealand, which examined the impacts of climate change on invasive species movements and establishment, with the goal of updating the Regional Biosecurity Plan for Micronesia and Hawai‘i.
