In this lecture from the International Conference on Sustainability, Transition and Culture Change, Peter Bane, author of The Permaculture Handbook: Garden Farming for Town and Country and publisher of Permaculture Activist Magazine explains the fundamental principles of permaculture.  One of the roles of Permaculture he says, is to remove basic subsistence needs from the money economy.  As well as access to clean food, water and energy, he includes education and rebuilding of the household economy as part of our basic subsistence needs. Permaculture aims to turn the household back into a place of production, not just consumption.
