Permaculture is a word originally coined by Bill Mollison and David Holmgren in the mid 1970's to describe an "integrated, evolving system of perennial or self-perpetuating plant and animal species useful to man"
A more current definition of permaculture, which reflects the expansion of focus implicit in Permaculture One, is 'Consciously designed landscapes which mimic the patterns and relationships found in nature, while yielding an abundance of food, fibre and energy for provision of local needs. People, their buildings and the ways in which they organise themselves are central to permaculture. Thus the permaculture vision of permanent or sustainable agriculture has evolved to one of permanent or sustainable culture.
More precisely permaculture is a
"design system based on ecological principles" which provides the organising framework for implementing the above vision. In this more limited, but important sense it draws together the diverse skills and ways of living which need to be rediscovered and developed to empower us to move from being dependant consumers to becoming responsible producers.
In this sense, permaculture is not the landscape, or even the skills of organic gardening, sustainable farming, energy efficient building or eco-village development as such, but can be used to design, establish, manage and improve these and all other efforts made by individuals, households and communities towards a sustainable future.
