Permaculture: A Designers’ Manual is the definitive permaculture design manual by Bill Mollison since 1988. This manual is the textbook and curriculum for the 72-hour certificate course in permaculture design.

Permaculture is a design philosophy that focuses on the design of human systems based on natural ecosystems. It is based on the idea that we often take for granted the origins of our food, water sources and building materials.

Permaculture is a harmonious integration of the landscape with people who provide food, energy, shelter and other material and intangible needs in a sustainable way.
