Not surprisingly, Permaculture tends to end up looking a lot like a Fukuoka system. Both arose from an observation of Nature so we shouldn’t be too surprised. Bill Mollison, the original designer of the system started by observing Nature in the rain forests of Tasmania.
The underlying principle is to re-create the complex webs of natural systems in a manner which provides surpluses for human consumption. The more perennial the system, the longer lived and, over time, the less maintenance required by humans.
Each piece of land, from unit balcony to 50,000 acre farm has a specific design planned for it. This plan is dependent upon the local, micro climate, designer and culture.
The study of Permaculture is a lifelong observation of living systems.
