Permaculture is a whole-systems approach of working with nature to design sustainable landscapes and systems. The methodologies are scalable and applicable to small home gardens up to communities as a whole. Principles are derived from the natural world and time-tested.
In the late 1960s, Bill Mollison and David Holmgren started developing ideas about stable agricultural systems. Dangers of the rapidly growing use of industrial-agricultural methods sparked these ideas. In their view, these methods were highly dependent on non-renewable resources, poisoning the land and water, reducing biodiversity, and removing billions of tons of topsoil from previously fertile landscapes. They responded with a design approach called permaculture, first made public in 1978 with the publication of Permaculture One.
Originally a combination of permanent and agriculture, the term was broadened to permanent culture from inspiration from the natural farming philosophies of Masanobu Fukuoka with understanding that social aspects are integral to a sustainable system.
After Permaculture One, Mollison further refined and developed the ideas by designing hundreds of permaculture sites and writing more detailed books, such as Permaculture: A Designers Manual. Mollison lectured in over 80 countries and taught his two-week Permaculture Design Certificate to hundreds of students. Mollison "encouraged graduates to become teachers themselves and set up their own institutes and demonstration sites. This multiplier effect was critical to permaculture's rapid expansion."
Several individuals revolutionized permaculture concepts. J. Russell Smith, in 1929, used an antecedental term for permaculture in the title of Tree Crops: A Permanent Agriculture, a book which summarized his extensive experimenting with fruits and nuts as crops for human food and animal feed. Smith saw the world as an interrelated whole and suggested mixed systems of trees and crops underneath. His book inspired many individuals intent on making agriculture more sustainable, such as Toyohiko Kagawa who pioneered forest farming in the 1930s.
P. A. Yeomans popularized an observation-based approach to land use in the 1940s and keyline design as a way of managing the supply and distribution of water. In his 1964 book Water for Every Farm, Yeomans defines permanent agriculture as one that can be sustained indefinitely.
Holmgren noted Stewart Brand's works as an early influence to permaculture. Other early influences include Masanobu Fukuoka, Ruth Stout, and Esther Deans who, in the 1930s and 40s, began advocating no-till gardens, orchards, and natural farming.
