Have you heard about any recent strategies for cooperative gardening in public spaces? Seattle and Olympia have food forests and edible landscaping areas. We are developing some in Portland. Some people I know have started growing vegies on unused private lands with permission from landowners. Have you heard about any recent methods along these ways? We could help to feed and educate millions this way.
BNAN, Boston Natural Area Network has a great program of working with immigrant and refugee families to establish community gardens. Creating a project under another community non-profit is easily done and could be a ringer to getting local zoning in your favor, plus there would be awesome growing knowledge with an immigrant community. Just a thought..
