“the development of agricultural ecosystems intended to be sustainable and self-sufficient.”
However, permaculture is much more than just self-sufficient, sustainable agriculture.
We look to Graham Bell, as stated in his book, The Permaculture Way, for a greater, more wholesome definition:
“Permaculture is the conscious design and maintenance of agriculturally productive systems which have the diversity, stability, and resilience of natural ecosystems. It is the harmonious integration of the landscape with people providing their food, energy, shelter and other material and non-material needs in a sustainable way.”
