Permaculture is a term coined by Bill Mollison and David Holmgrem, at the end of the 70s, in Australia, for a proposal for a system of planning and productive design of human settlements that accommodates all their needs, without degrading our natural environment. All this by observing the dynamics of the ecosystems and nature itself.
It comes from the combination of two words: PERMANENT + CULTURE

Etymologically, permanent comes from the Latin permanentis, which means to remain until the end, to maintain continuity, which is always in the same place, to preserve. And, for its part, culture comes to us from culture, and this from cultus (cultivation). It is interesting to go to the etymology of the words because it tells us where they come from and what their relatives are. It is like the root of the word human, which is the same as humble and humus. That is to say, from humus derive the words human, humble, man... All of them coming from the Indo-European root "dhghem" which means land, of earth. So we could say that making hummus is an act of humility with which no harm is done to any being: which makes us more human. According to Mollison, Permaculture “is a design for the creation of sustainable human environments”. Later, coining the term, he copyrighted it so that it would not fall into the University, where it would surely degenerate and die.
