Natural ecosystems provide the best possible example of this operational principle.
Permaculture is a philosophy of working with, rather than against, nature; of protracted and thoughtful observation rather than protracted and thoughtless action; of looking at systems in all their functions rather than asking only one yield of them and of allowing system to demonstrate their own evolutions.
The idea behind permaculture principles is that generalised guidelines can be derived from the study of both the natural world and pre-industrial sustainable societies, and that these will be universally applicable to fast-track the development of sustainable use of land and resources, whether that be in a context of ecological and material abundance or one of deprivations.
Permaculture principles are brief statements or slogans that can be remembered as a checklist when considering the inevitably complex options for design and evolution of ecological support systems.
These principles are seen as universal, although the methods that express them will vary greatly according to place and situation.
