Contour Stone Lines slow down runoff, increase water infiltration, and sediment is captured behind these semi-permeable barriers, improving production. A perennial grass can supplement the lines where stone is scarce. Suited to low slopes, high runoff and hand labour. This technique is readily adopted by resource-poor farmers and can lead to a harvest even in years with low and erratic rainfall.
