There's not even a nod to the guys that coined the term.
Writer Emma Chapman defines it as:
“Permaculture, originally ‘Permanent Agriculture’, is often viewed as a set of gardening techniques, but it has in fact developed into a whole design philosophy, and for some people a philosophy for life. Its central theme is the creation of human systems which provide for human needs, but using many natural elements and drawing inspiration from natural ecosystems. Its goals and priorities coincide with what many people see as the core requirements for sustainability.”
