Permaculturists employ techniques from a broad range of disciplines. These tools are selected and applied according to how well they allow permaculture's principles to be applied.
Permaculture is practical, grass roots sustainability in action. It provides immediate tools for people to reduce their environmental footprint and build resilient communities. It is a creative design process that is based on ethics and design principles. It guides us to mimic the patterns and relationships we can find in nature and can be applied to all aspects of human habitation, from agriculture to ecological building, from appropriate technology to education and even economics. When applied to gardening it suggests that not only can we grow food almost anywhere - from fruit shrubs in patio pots to vines on fences - but we can get higher yields with less effort simply by mimicking nature.
