"Our land massively degraded, our poles wobbling and disintegrating from climate change, and our national and global economies in the midst of immense metamorphosis. These are catastrophic cries from the land.
"In measured response to the context of our environment and our economy, thousands of urban and suburban community gardens and farms have taken root in North America over the last 15-20 years.
"Community farms and gardens – located in cities, suburbs and countryside – have established pathways that can lead to a healthy, sustainable foundation for our transition and our future.
"These farms and gardens are keystone models that – if widely emulated – can help us address step by steady step our crises of land and climate degradation, as well as a host of economic and dietary imperatives."
