Permaculture is a design approach that takes patterns from nature as models. The document discusses 12 permaculture principles: (1) Design from patterns to details - observe patterns in nature that can form the backbone of designs; (2) Integrate rather than segregate - put the right elements in the right places so they support each other; (3) Use small and slow solutions - small systems are easier to maintain than big ones. The document assigns homework on applying the principles and recognizing patterns in projects. It provides resources on permaculture including videos and websites.
