Permaculture is a landscape and settlement design movement that focuses on learning from observation of nature and ecosystems, systems thinking, and taking a long-term perspective. In the context of agriculture and horticulture, permaculture promotes the creation of food-producing ecosystems that require minimal ongoing human intervention. This often entails the use of perennials instead of annuals, minimising chemical inputs, the use of polycultures over monocultures, minimising soil disturbance, incorporating livestock and crops into the same system, agroforestry systems, and compost production. Permaculture shares some principles with and is related to various other 'natural' farming movements including agroecology, organic farming and regenerative farming.
