PERMACULTURE

 A Designer’s Manual, Bill Mollison suggests:

• That the systems we construct should last as long as possible, and take least maintenance.
• These  systems, fuelled by the sun, should produce not only for their own  needs, but the needs of the people creating or controlling them. Thus,  they are sustainable, as they sustain both themselves and those who  construct them.
• We can use energy to construct these systems,  providing that in their lifetime, they store or conserve more energy  than we use to construct them or to maintain them.

In all Permaculture design we also strive to work with natural  principles, learning from nature and attempting to harmonise in a way  such that we are able to regenerate degraded land and create natural  systems that support us as human beings on planet earth.

Permaculture as a subject is vast and spans many disciplines as an  understanding of a myriad of areas is needed to grasp how a design is  able to function.
