SkyFarm; turning our skies green

the world’s first edible high-rise

Is it a bird? No… Is it a plane? No… it’s a… “SkyFarm”. Just when you thought the skies were growing grim with CO2, Toronto scientist Gordon Graff has created plans for a 58-floor concept building – the SkyFarm – which would grow crops in the heart of the city and could provide enough food for 35,000 people every day.

Wow, the potential of city-based farming could be vastly expanded if we extend upwards as well as using ground-level plots. Of course, one major problem with growing produce on our roofs is the quantities of soil needed, which would add unfeasible amounts of weight. However, hydroponic technology – using nutrient-enriched water instead of soil – could be the solution. Crops would be irrigated by water recycled through the building’s hydroponic system and, with no soil, many diseases are ruled out – meaning no need for chemical pesticides.
