The French Polynesian islands are among the most vulnerable areas in the world to flooding due to rising seas stemming from climate change.
As sea levels rise, low-lying islands around the world including French Polynesia could have portions of land overtaken by the ocean or even disappear altogether. The French Polynesian government recently signed a memorandum of understanding with San Francisco's Seasteading Institute to design the world’s floating city—a resiliency approach that has never before been attempted.
The project "opens the capability of gaining new living spaces for countries threatened by rising water levels, overpopulation, or other dangerous phenomena," the memorandum states. The concept calls for solar arrays and wave-driven turbines to power the floating community.
Construction would start in 2019, if all goes well.
