As we have learned when we were focussing on mega-cities, by 2050, an estimated two-thirds of the world’s population will live in urban areas, imposing even more pressure on the space infrastructure and resources of cities, leading to social disintegration and horrific urban poverty. To grow enough food to feed the people, if traditional farming practices continue as they are practiced today, an estimated 109 hectares of new land (this about 20% more land than is represented by the country of Brazil) will be needed. Today, almost all of the fertile ground all over the world is in use. New solutions have to be developed to avoid an impending disaster.

A potential solution to approach the problem is skyfarming. Skyfarming or vertical farming is a conceptual form of agriculture done in urban high-rises. In these high-rises (also called "farmscrapers") food such as fruit, vegetables, fish, and livestock can be raised by using greenhouse growing methods and recycled resources year-round, allowing cities of the future to become self-sufficient.
