Le Keyline Design – Méthodologie

Keyline Design is a land and water management method developed by P.A. Yeomans, designed to regenerate soils, improve water distribution, and increase landscape fertility. It focuses on identifying a keypoint in the terrain—a subtle change in valley slope—and drawing keylines from this point to guide the placement of furrows, trees, roads, and water management features. Using a specialised plough, these furrows enhance soil aeration and water infiltration, redistributing runoff from valleys towards ridges to maximise moisture retention. This approach supports sustainable and resilient agriculture by working in harmony with natural topography and ecological processes.
