keep land for the growing, hungry population - farm upwards!

With more and more people needing housing and feeding, keeping the land for homes and putting crops in skyscapers could make sense.

Most of the constructions shown at this web-site are speculative designs. We do not know whether they will make economic and energy sense.

[Note that the linked web-site is somewhat clumsy with their handling of image files.]

Skyscraper farm proposal by Chris Jacobs.  Image: http://www.verticalfarm.com/Designs.aspx“By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today.”

“Vertical farms, many stories high, will be situated in the heart of the world's urban centers. If successfully implemented, they offer the promise of urban renewal, sustainable production of a safe and varied food supply (year-round crop production), and the eventual repair of ecosystems that have been sacrificed for horizontal farming.”

Presentation with a lot of analysis.
