A new study forecasts the potential impacts of erosion in 48 Alaska coastal communities. The results are both surprising communities and helping them get funding to adapt.
But anecdotal evidence of erosion can sometimes be insufficient proof when applying for grants.
Several grants that help communities facing environmental threats, like the U.S. Department of Housing and Urban Development Imminent Threat Program and the Federal Emergency Management Agency’s Hazard Mitigation Assistance Program, require a third party to verify the threat exists. That’s what this new study helps to do.
Jessica Lewis-Nicori is a tribal council member and a high school science teacher in Chefornak, another village in the Yukon-Kuskokwim Delta. She said that Chefornak used the state’s erosion assessment in a recent grant application to move five homes in the village that are in the most immediate danger due to erosion.
The erosion forecasts are created by measuring how much each community’s coastline has moved in the past to predict how much it will move in the future. That’s done by taking aerial images of each community, dating back from the 1950’s to present day. Those images are then mapped on top of each other and combined with data on where the community’s infrastructure is located.
