Peer-to-Peer Garden Sharing
"A full 40 percent of North Americans do not have their own yard space; those who do, meanwhile, often leave it underused. Aiming to match the haves with the have-nots anywhere there's a similar inequity, Sharing Backyards partners with local community organizations to create land-sharing programs in diverse regions around the world.
Similar in many ways to UK-based Landshare, Sharing Backyards is a project of LifeCycles, a Canadian nonprofit dedicated to cultivating awareness and initiating action around food, health and urban sustainability in the Greater Victoria, B.C., community."
