Dwindling land, expanding population . . . where will we grow our food? The back- or even front yard vegetable garden is gaining in popularity. Yet even "yards" are a dwindling phenomenon. So, where do we go?
"Up", some say - and inner city gardens are beginning to catch on. At a recent Sustainable Buildings Canada gathering in Toronto, reported by the Toronto Sun, there were advocates urging us to go higher:
Graff, a master's student in architecture at the University of Waterloo, is urging us to see acreage in stacks, not spreads: his prototype for vertical agriculture – aptly dubbed "Skyfarm"– climbs 59 storeys, with intensive hydroponics packed onto every level.
By his calculations, Skyfarm could grow enough food for 50,000 people a year – nowhere near enough for a substantial portion of the city. But install several Skyfarms in neighbourhoods throughout any major metropolis, and the prospect is tantalizing.
