This document introduces permaculture, which involves designing sustainable human settlements and agricultural systems modeled from natural ecosystems. It discusses the core principles of permaculture design, which include placing elements in their relative locations for mutual benefit, designing systems with multiple functions and elements, efficiently planning for energy needs, using biological resources, cycling energy and materials, creating intensive small-scale systems, accelerating ecological succession, maintaining diversity, utilizing edge effects, and adopting supportive attitudes. The overall goal of permaculture is to meet human needs for food, shelter, and community in sustainable ways that care for the earth and people.
