Experts Focus on Coastal Inundation at Pacific Hazards Meeting
Flooded houses. Inundated farmland. A collapsed seawall. Mud-filled roads. Contaminated taro patches. These were among the graphic images of devastating high-tide coastal inundation events in the Pacific that were presented at the annual Pacific Partners meeting of the Pacific Risk Management ‘Ohana (PRiMO), held in Tumon, Guam, on the 18th and 19th of March, 2009.

PRiMO is a consortium of local, national, and regional agencies, institutions, and organizations committed to enhancing hazard resilience in the Pacific. This year’s meeting, which focused on inundation-related coastal hazards, was attended by approximately 80 participants representing governments, academia, and non-governmental organizations. Historically held in Honolulu, the meeting was moved to Guam this year to facilitate the participation of partners from the Western Pacific.

The images mentioned above, which were presented by Johannes Berdon, Officer in Charge at the NOAA National Weather Service station in Chuuk, Federated States of Micronesia, were encountered during the December 2008 high-tide inundation event in Chuuk – one of a number of Pacific island locations that recently experienced inundation. The Chuuk event occurred because of a combination of several factors: a high surf event, a northern swell, and a higher La Nina sea level. Some of the seawater went 70 to 100 feet inland and contaminated ground water within hours.

Other speakers at the meeting included the Honorable Felix P. Camacho, the Governor of Guam, who expressed his support for PRiMO and encouraged efforts to work together to develop and deliver timely risk management information and services. Other speakers addressed tropical cyclone driven storm surge, Pacific Island tsunami inundation modeling, and threats from sea level rise.

“Capturing the social, physical, economic, and environmental impacts of inundation events like this on low-lying islands is of great help to decision makers,” said Dr. Melissa Finucane, a Senior Fellow at the East-West Center and Principal Investigator of Pacific RISA, a program designed to facilitate the management of climate risks in the Pacific. “Combining quantitative information from models and physical assessments with qualitative information from narratives and pictures helps coastal communities to evaluate the risks being faced and what needs to be done in response to those risks.”

The importance of assessing the socio-economic vulnerability and resilience of Pacific Islanders to inundation hazards was addressed by Cheryl Anderson, Director of the University of Hawai‘i Social Science Research Institute and Co-Investigator on the Pacific RISA project. “Understanding the short-term and long-term costs of inundation events is key to preparing for and mitigating the impacts of potential hazards,” said Dr. Anderson.

A substantial portion of the meeting involved small-group discussions to identify needs and gaps in knowledge related to hazard and community resilience information. The meeting identified actions and opportunities to enhance communication and collaboration among people involved in risk management around the region.
