Inaugural Lecture BlueRevolution


Published on

This is my Inaugural Lecture about the Blue Revolution. It shows that we need to ralize urban expansions on the water and combine this with floating food production and floating algae biofuel production to deal with the challenges of the 21st century. Much of the work was developed with my colleagues at DeltaSync. We want to collaborate with people all over the world to develop pilot projects and expand on the water in a sustainable way. it goes much further than being self-sufficient. The purpose is to create a symbiosis between cities on land and water. Floating cities could use the waste CO2 and nutrients of land based cities in a productive way, providing at the same time affordable flood proof housing for the people. Most of the building blocks are there. We need to bring it together to make the next step. Because only a small part of the ocean is needed, the rest can become a nature reserve giving marine ecosystems a long term perspective on survival. A perspective that is currently lacking. We look forward to receive comments and ideas. Best regards,

Rutger de Graaf

Global potential 44% of the world food demand can be met by using the available (waste) nutrients and CO2 from current cities A total floating area of the size of Madagascar (585.000 km2) would be enough . In the optimal ratio, 13% of the population would live in the floating cities.

  55. 55. Conclusions A fundamental new approach to urban development is needed for the challenges of the 21st century Cities on land should be transformed into flood proof ecocities Floating city expansions combined with food production can accommodate future urbanization without sacrificing land At the same time this strategy provides global food security and reuses waste of conventional cities Much research is still needed but, at the same time, also fast implementation
