David Holmgren - Co-originator of Permaculture.

A more current definition of permaculture, which reflects the expansion of focus implicit in Permaculture One is, 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.
