As permaculture evolves, it becomes increasingly evident that achieving a resilient, regenerative harmony between humans and natural systems requires the conscious cultivation of strong and lasting beneficial relationships among people. Terra Verde considers permaculture design strategies for the invisible structures that tie us together: our families and households, community groups, organizations, legal systems, and even governments. Delia Carrol of Little Hill Garden Arts, Melora Golden of Recode, and Kat Steele of Esalen and the Urban Permaculture Guild share their experience with the emerging discipline of social permaculture.
