Two Australians coined the term in the mid-1970s: Bill Mollison, a naturalist and teacher, and David Holmgren, then his student. Their 1978 book Permaculture One put it into the world. Mollison taught it everywhere; Holmgren gave it an intellectual spine, later distilling the practice into twelve design principles. Neither claimed to have invented the underlying wisdom.

Older work: Masanobu Fukuoka’s natural farming, P. A. Yeomans’ Keyline water design, J. Russell Smith on tree crops, Howard Odum’s systems ecology, and the accumulated knowledge of Indigenous and traditional land practice the world over. Its own contribution was to weave those threads into one framework a person could learn and test on their own ground.

Three ethics: care for the earth, care for people, and a fair share of the surplus returned to both. From those come working principles — observe and interact, catch and store energy, produce no waste, use edges. Tools like zones and sectors organize a site by how often you tend it and how sun, wind, and water move through it.

By teaching. The Permaculture Design Certificate — a 72-hour course Mollison codified in the 1980s — let the system replicate person to person, with no central authority and no franchise. That open structure carried it from Tasmania to drylands, cities, and smallholdings on every inhabited continent, reshaping itself to fit each one.

Satellite imagery, LiDAR, and drones can read a site’s water and contour before a shovel breaks ground. Inexpensive sensors track soil moisture and microclimate across whole seasons. Design software models the guilds and flows that once lived only in a notebook. None of it replaces observation; it extends it. That meeting is where I work.
