Defining permaculture and placing it in the context of the green movement, this book is divided into three parts: Part One: The principles underlying permaculture as applied to soil, fertility, water, climate, microclimate, energy and materials. Part Two: Applying permaculture to buildings, gardens, orchards, farming, woodland and biodiversity. Part Three: The permaculture design process in action, how to develop your home or project on permaculture lines, plus many useful skills and techniques.
