| In order to explore the conditions of successful irrigation management, this study investigates the determinants of household contributions to the cleaning of irrigation channels and the availability of water. By using primary data collected in an irrigation scheme in Uganda, we find that household contributions to the cleaning of irrigation channels are determined by the scarcity of irrigation water, opportunity cost of labor, and private benefit associated with plot size. We also find that the availability of irrigation water increases in the tertiary irrigation area where the coefficient of variation of plot size is large. |
