The term Permaculture was first coined by two Australians David Holmgren and Bill Mollison in the 1970s and was defined further when they published Permaculture One in 1978.
The Permaculture vision of permanent or sustainable agriculture has now evolved into the broader concept of permanent or sustainable culture. Permaculture is essentially a design system based on ecological principles, which provides an organising framework for a regenerative, sustainable future. David Holmgren defines Permaculture as “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.”
In three decades the movement has now grown into an international network with thousands of system designers on every continent on the planet. Permaculture has been described as one of Australia's most significant “intellectual exports” (Holmgren, 2009).
