Permaculture Design is a discipline that originated in Australia in the late 70’s, when Bill Mollison and David Holmgren’s book “Permaculture One” was published (1978). The term Permaculture comes from “permanent agriculture” (the design and creation of stable, long lasting and sustainable agricultural systems modelled from natural ecosystems) and permanent culture (the design of human habitats organically integrated in the natural ecosystems, which includes social aspects). Permaculture covers a wide field of knowledge and subjects, including ecological and regenerative design and engineering, integrated water resources management, environmental design and construction, agroforestry and sustainable farming, in general all the disciplines that relate to the creation of a sustainable human settlement, including economy and sociology. From observation of nature and its cycles, Mollison and Holmgren derive the design principles, for example, Observe and interact, Catch and Store Energy, Obtain a yield (Holmgren), and Every element has more than one function (Mollison). The lessons learnt by human civilization over the centuries are translated into Mollison’s Permaculture attitudes (the problem is the solution, work with nature and not against it, smallest change for the greatest effect, etc.). From observation of human history and culture, they identify the three Permaculture ethics: Earth Care, People Care, Fair Share. Other important elements in Permaculture design and strategy are: the Layers of trees and animals present in mature ecosystems; the Guilds, groups of animals and plants that naturally support each other, the Zoning system, from zone 0 to zone 5 (usually interpreted from the house to the wilderness); the Sectors (the impact of natural factors – like sunlight, wind, water, view – on the design); the Keyline design, a core strategy to keep water in the soil and increase its fertility and biodiversity.
