Permaculture is a systemic and comprehensive approach to design systems (eg, human habitats and agricultural systems, but this can be applied to any system) based on natural ecology (biomimicry) and the tradition. It is not a fixed method but a “mode of action” that must take into account the bio-diversity of each ecosystem. It aims at sustainable agricultural production, which is very energy efficient and respectful of living beings and their reciprocal relations, while leaving “wild” nature as much room as possible.
