David Holmgren is best known as the co-originator with Bill Mollison of the permaculture concept following the publication of Permaculture One in 1978. Since then he has written several more books, developed three properties using permaculture principles, conducted workshops and courses in Australia, New Zealand, Europe and Japan. Within the growing and international permaculture movement, David is respected for his commitment to presenting permaculture ideas through practical projects and teaching by personal example, that a sustainable lifestyle is a realistic, attractive and powerful alternative to dependent consumerism. As well as constant involvement in the practical side of permaculture, David is passionate about the philosophical and conceptual foundations for sustainability, which he explored in Future Scenarios: How Communities Can Adapt to Peak Oil and Climate Change(2009), and Permaculture: Principles and Pathways Beyond Sustainability (2003). With an increasingly high profile as a public speaker, David Holmgren provides leadership with his refreshing and unorthodox approach to the environmental issues of our time.
David lives with his partner Su Dennett and their son Oliver at "Melliodora", a one-hectare permaculture demonstration site at Hepburn Springs, Central Victoria, Australia. Visit his web site at www.holmgren.com.au.
