The word permaculture is derived from two words ie permanent and agriculture. Thus the words permanent agriculture and permanent culture hence sustainable agriculture and land use ethics. It is a design system for creating sustainable human environments through existing on the earth by using energy that is naturally in flux and relatively harmless, and by using food and natural resources that are abundant in such a way that we don’t continually destroy life on earth (Introduction to permaculture by Bill Mollison). A cornerstone of permaculture philosophy is to turn problems into opportunities, and apparent "wastes" into resources. A Permaculture system can be maintained using a minimum of materials, energy and labor. By recycling "waste “resources back into the system, it also minimizes pollution. it serves human needs efficiently by incorporating useful, high-yielding species. A Permaculture system is designed to be diverse, so that even when one element fails, the system has enough stability and resilience to thrive. This gives it greater potential than a conventional system for long term economic stability.
