A fundamental new approach to urban development is needed for the challenges of the 21st century
Floating city expansions combined with food production can accommodate future urbanization without sacrificing land.
At the same time this strategy is both climate adaptation and mitigation.
Technology is there. Research needs to be done parallel to fast implementation.
Floating cities construction is part of a wider societal transition in which governance is crucial
