The Australian PA Yeomans introduced in the 1950s the concept of Keyline Design used to passively harvest water on a site and rehydrate the landscape. This approach to design strongly influenced the founders of permaculture.
From his work in natural farming, the rather progressive Japanese farmer Masanobu Fukuoka is recognized worldwide as a pioneer of permaculture. He worked on sustainable and autonomous agriculture and autonomous where human intervention is limited to mulching and sowing.
In the mid-70’s, Bill Mollison and David Holmgren developped the idea of a ‘permanent agriculture’ systems, which they called “permaculture” and which later formed a ‘permanent culture’ as the social / ethical ties seemed essential to ensure a sustainable system.
