Blue Revolution

Date: September 2012
Place: Delta cities

With the predicted scarcity of water, fossil fuel and food resources, the necessity to develop floating cities is greater than ever before. The current food crisis almost 1 billion people suffer famine today shows that world food production systems have trouble keeping up with rapid increase of global population and prosperity. Agricultural productivity is lagging because the prime resources, water, phosphates and fossil fuels, are under pressure and at the same time increased urbanization will swallow up nearly a fifth of the fertile croplands by the end of this century.

Food scarcity will be, above all, a land scarcity issue. If part of the future urbanization and food demand can be met by relocating it on the oceans, a sustainable solution can be offered. And floating food cities have additional benefits. The first benefit is that nutrients that are wasted by conventional cities may be reused to grow algae, fish and crops. The second benefit is that the risk of flooding will be averted, saving billions of dollars every year and the third benefit is that opportunities are created to apply new technologies of water and energy production, that would not yet compete with conventional systems on land.

Especially now, in times of crises, a new and convincing perspective that enables us to correct the errors of cities on land is vital. In order to create cities where people can live truely more sustainable and with a clear conscience.
