Presentation about the BlueRevolution and how floating productive urban developments can provide a perspective to deal with flobal challenges such as climate change, land scarcity, urbanization and population growth. The concept includes floating urban expansions, floating algae and seaweed and aquaponics systems. Feasibility for delta cities such as Rotterdam, Jakarta and Manila is elaborated. Concrete examples of realized projects.

  46. 46.  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 Conclusions
