Abstract
⺠We surveyed subsistence households along the Senegal River Valley in Mauritania. ⺠Traditional cropping does not provide sufficient human digestible energy. ⺠There is no shortage of labor when irrigated rice is combined with traditional cropping. ⺠There is a negative return of rice production to labor and inputs. ⺠Rice negative returns explains observed gradual abandonment of irrigation schemes.
