The concept of permaculture can be difficult to define. Often people have a basic understanding but find it hard to really grasp the concepts behind it that make it different from just organic gardening or sustainable living. What sets permaculture apart is that it is based on design, permaculture principles and the three ethics of earth care, people care and fair share.The permaculture concept was created by Bill Mollison and David Holmgren at the University of Tasmania in the 1970s. David was Bill’s student and together they published the groundbreaking Permaculture One, (Corgi, 1978) which offered the first description of what permaculture was.After this book was published, David and Bill went their separate ways. Bill travelled the world, spreading the word of permaculture. David set about gaining skills and putting what he had come up with into practice.
