is a form of whole systems design based on the sustainability of natural systems, seeking to reproduce that sustainability in our living environment. Permaculture designs differ based on climatic factors, bioregion, organizational goals, personal preferences and other factors. It can hence be said that permaculture is, at its core, a set of thinking tools, in particular towards awareness of context, threats and opportunities.
Though it was developed out of sustainable agriculture, permaculture design is hypothetically applicable to any field of human endeavor. The very term "permaculture" itself was first used to mean "permanent agriculture," it is now applicable to all realms of design and is now considered to mean "permanent culture".
