Circles of Hope: Circular Buffer Strip Schemes for Agriculture – Dr Sangamesh Angadi, New Mexico State University

Agriculture in the semi-arid US Southern Great Plains depends on irrigation water from the Ogallala Aquifer, the largest in the country. With the aquifer in decline, new ideas will be needed to ensure the future of irrigated agriculture in the region. Dr Sangamesh Angadi and his colleagues at New Mexico State University have come up with a simple, cost-effective system of interspersing crops in circular pivot fields with rings of native grasses, to buffer against the effects of damaging winds, improve water cycle, reduce soil erosion, and improve ecosystem services.
