I estimate the impacts of irrigation canals on annual crop productivity and the structure of the agricultural sector in South Africa. I use remotely sensed measures of crop yields and a novel land cover classification dataset in a regression disconti- nuity framework with relative elevation to the nearest canal as a running variable. I find that canals increase yields of two major crops (maize...
