"Permaculture Design is the first system of conscious functional design in the world; that's its unique aspect, and functional design is sustainable."
- Bill Mollison
It was based on a SIMPLE QUESTION related to the design of agriculture.
"If most of nature is dominated by perennial plants, trees, and other longleaf plants, why is our agriculture dominated by annual crops? Why doesn't it follow the design rules of nature? "
We have gotten used to the idea that for any sort of key problem or important activity, there is one big solution that trumps all others, and some version of it ends up everywhere.
Once we start dealing with nature, local resources, and local situations, then the design solutions are all different.
When you look at a whole system, there are TWO THINGS very undesirable. One is WORK and the other one is POLLUTION.
POLLUTION is a product of WORK.
WORK is a result of not supplying every component of your system with its needs.
EXAMPLE BELOW
If you didn't put a tank on your chicken house, you gotta carry water to the chickens. So you incur WORK.
Now, if you don't collect the eggs from the chicken house, that's POLLUTION.
So, POLLUTION is an unused resource. It didn't go somewhere where it would be used.
Permaculture is actually the whole way we relate to nature. And so, human settlement, the design of houses, and the way we organize everything in society is part of it.
It comes from two Latin words. 'PERMANENS' (to persist indefinitely), and 'CULTURE' (the practices that support human occupation).
Put those together; It's a persistent system that supports human existence.
