Keyline Scale of Permanence

The Keyline Scale of Permanence is a planning tool used in sustainable land design. It prioritizes elements of a landscape based on their permanence and influence, starting from the most permanent features like water sources and topography, then moving to less fixed features like trees, roads, and structures. By arranging land uses this way, it helps create resilient, adaptable systems that work harmoniously with natural characteristics. Essentially, it provides a framework for designing land and agricultural systems that respect ecological stability and long-term sustainability.
