The document discusses concepts related to soil conservation and permaculture, including unparallel contour patterns, keypoint locations, and keyline irrigation systems. It also references various permaculture projects conducted by Australia Felix Permaculture from 1995 to 2007, including forestry, agroforestry, and silvopastoral designs. Additionally, it presents the Keyline Scale of Permanence for planning sustainable landscapes based on the relative permanence of climate, land shape, water, roads, trees, buildings, subdivision, and soil.
48. KEYLINE SCALES OF PERMANENCEThis concept helped solve problems of priority in the design of the farm landscape. The Keyline Scale of Permanence is an order for planning based on the relative permanence of the various items, which together make up the completed landscape. It can be successfully applied to the design of the town and city landscapes.The Keyline Scale of Permanence is:1. Climate2. Land shape3. Water4. Roads5. Trees6. Buildings7. Subdivision8. Soil
