It gets to the fundamentals of life on earth through the energetic principles and foundations of ecosystems and civilizations and teaches us how to design with them, just as nature does, to build symbiosis into our lives again. Using the principles, permaculturists have been able to re-green deserts, restore hydrological cycles, reduce and/or eliminate their carbon footprint and many of these practices that permaculture has pioneered or adopted have been recently recognized as the top strategies to stop or reverse climate change in Paul Hawken’s new book, Drawdown.”

“A student of the originators of Permaculture, (Bill Mollison and David Holmgren), Braden has gone on to study with many other leaders in the field. He has been teaching and consulting with this knowledge since 2007 and has taught at places as varied as  the Earthship Academy, Haitian Farmers and the Haitian Ministry of Agriculture on behalf of USAID and currently teaches at Xavier University, University of Cincinnati and the Cincinnati Permaculture Institute (, where he is the Executive Director.
