Floating cities have been proposed by designers, researchers and organizations all over the world as a solution to the expected effects of climate change and land scarcity, or as a way to create opportunities for societal and political change.

While the number of visions and designs for floating cities is impressive, the actual implementation to date remains limited to small-scale demonstration projects. The Seasteading Institute however produced a business case to develop the first seastead. The main findings and recommendations were put together in a report; the Seasteading Implementation Plan.
