P.A. Yeomans

P.A. Yeomans was an Australian engineer and author known for developing sustainable land management techniques, especially for dry areas. His most notable creation is the "Keyline System," a method that optimizes water distribution and soil fertility by designing a landscape to harness rainwater effectively. This approach helps prevent erosion, improves agricultural productivity, and promotes environmental health. Yeomans’ ideas emphasize working with natural land contours and water flow, making farming more sustainable, especially in arid and semi-arid regions. His work has influenced modern permaculture and regenerative agriculture practices worldwide.
