Permaculture: Principles and Pathways Beyond Sustainability

David Holmgren, who developed the idea of permaculture, has expressed in this book one of the most complete visions of permaculture for a world of climate change and energy depletion. Holmgren is a very clear thinker and has assembled a consistent and elegant articulation of a set of principles for permaculture practice which have been implied elsewhere but never so well expressed.
