As posted before (window farms, gutter garden and guerilla gardening), growing food in a suburban environment is a hard thing to do. On Intercon I found an interesting article about a new type of farm: the vertical farms 101.
The full article can be found here, a summary below.
The basic idea of a vertical farm is not new. In vertical farms the benefits of architecture are combined with our knowledge on agriculture and the cycle of materials.
The goal of a vertical farm is to connect infrastructure, waste management and energy production with agriculture, thus creating fully operating, independent ecosystems (preferably in an urban environment).
At the moment we’re still talking concepts here, but recent tests have already proven that this idea will be possible in the near future (5 – 10 year). The scheme below (also from Intercon) shows how these vertical farms try to close the material cycle.
