The setting up of the River Basin Development Authorities (RBDAs) between 1975-76 and the World Bank assisted Agricultural Development Projects (ADPs) between 1980-86 were the milestone in the development of large scale irrigation schemes and of irrigated fadama (alluvial river bed), respectively in Nigeria. The developments of large scale irrigation projects in Nigeria were very fast in the first decade of the establishment of the RBDAs and later slowed down due to severe shortage of funds, total dependency of RBDAs on government grants, and non-participation of farmers in the project. Ultimately, the overall performance of the project declined sharply. And then the government's attention was diverted towards the small scale irrigation development through the exploitation of shallow groundwater in the fadama area under the ADP. Presently, a little over 100,000 hectares of land is under modern medium- large scale irrigation and around 181,000 hectares fadama under small-medium scale irrigation in the country. However if the existing water reservoirs are fully exploited and water efficiently used, the irrigated land could be increased by 3 to 4 fold. Presently the overall irrigation efficiency range is between 25-35 percent and 50-60 percent in surface and sprinkler irrigation systems, respectively. Most of the irrigation projects in the country suffer from the common problem of low water utilization efficiency, low productivity, and prominent head and tail effects caused by inadequate attention on operation and maintenance and effective farmer organizations. The irrigation water use for various crops varies in the region on one hand and on the other the choice of crops to be grown, cropping pattern and their intensity generally develop over the year on the basis of availability of water at farms. Therefore, the success and failure of any irrigation project depends ultimately on the productivity and the net return to farmers, which signifies the overall management performance of the irrigation system. This paper is aimed at examining the historical and current development of irrigation in Nigeria as well as the recent policy on management of the irrigation schemes.
