A UN-backed project has been proposed in South Korea to develop a floating city off Busan to the sea to pioneer a new mode of living amid climate-related sea level rise.
The Floating City Project is a joint effort of the UN Human Settlement Program (UN-Habit) and Oceanics.
The city will be built on the coast of Busan in South Korea and is expected to be completed by 2025.
The floating city will have flood-proof infrastructure and will include several man-made islands to eliminate the risk of flooding.
Although the size of the first iteration of the city has not been determined, the cost is expected to be in the region of $200 million.
The self-sustaining city will be specially designed to withstand natural calamities like tsunamis, floods and Category 5 hurricanes.
