The central concept of perma culture is maximizing useful connections between components and synergy of the final design. The focus of perma culture … is… on the relationships created among elements by the way they are placed together; the whole becoming greater than the sum of its parts. Perma culture design therefore seeks to minimize waste, human labour , and energy input by building systems with maximal benefits between design elements to achieve a high level of synergy. Perma culture designs evolve over time by taking into account these relationships and elements and can become extremely complex systems that produce a high density of food and materials with minimal input.” Seed pelleting, ploughing , water harvesting, useful climbing plants, poly culture , mulching, soil rehabilitation and tree establishment in deserts are some instruments of perma culture .
