Large scale irrigation potential has been developed in the past two decades in Sahel and Sudan Savanna zone of West Africa. The total irrigated area is likely to exceed 2m ha. In view of the high cost involved and to make the most efficient use of irrigation water, crop choice, time of growth and climate should be closely matched for optimum crop productivity. Results showed that the crop intensity can be increased from less than 75% in rainfed to 300% in irrigated farming. This paper suggests an irrigated cropping pattern based on the on-station research in the Sahel and Savanna zone of West Africa with special reference to Nigeria.

The Federal Government's recent policy to commercialize the Nigerian River Basin Development Authorities (RBDAs) that manage large scale irrigation systems, covering a little over 100,000 hectares of land under irrigation has forced authorities to become self-financing. The RBDAs are currently trying to generate more funds to survive while increasing the rate of water charge and its recovery rate. The present systems of management is not likely to improve the operation and maintenance efficiency due to several limitations even after collecting the recently increased (double) rate of water charges. Presently the overall irrigation efficiency of these large scale irrigation projects is about 25-35%; the relative water supply to sectors range from 20-60%, low cropping intensity (150-160%), and net return per unit area has decreased due to high cost of production and low crop yield. It means water allocation, distribution and scheduling, increase in cropping intensity, yield, and net return are likely to play major roles in improving the management. Proposals to expand the role of farmers in management are in the pipeline. Turnover of major management responsibilities (such as water distribution, allocation and scheduling, maintenance of delivery systems after the main canal, water fee allocation and socio-economic welfare) to the farmers could be one of the better solutions to efficient management of the system. Some of the activities such as project rehabilitation, land consolidation, effective crop production and resource allocation technology, and strengthening farmer organizations (water users' group in particular) are required before the turnover process begins. The possible modalities of partial turnover of management to farmers has been briefly discussed in this paper.

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.
