Peoples' programme A very significant feature of the small-scale irrigation programme is that with a bit of ingenuity and tact it can be made a 'peoples' programme', and the community's active participation can be secured in its implementation. This will not only cut the costs of such schemes substantially, but will also encourage the people to think of these schemes as their own, which is very important to the success of any programme undertaken in the public sector. Obviously such a personal attachment is missing in any largescale project. Separate small-scale irrigation departments need to be set up in both the federal and state governments to encourage development. The benefits of small-scale irrigation should not be overlooked, and the The ultimate aim is the optimum use of the soil and water resources, and the adoption of appropriate technology within the framework of the particular socio-economic structure. Only the careful use of both surface and groundwater together will have a dramatic effect on increased food production. Small-scale schemes are attractive because the initial outlay involved is small, they can be executed quickly and yield quick results, they normally require no special expertise or equipment, and local expertise and resources (including human resources) can be easily mobilized for their execution. The disadvantages, however, are their cost of maintenance, their relatively short life, and the limited protection they afford. Because of the current funding constraints; the urgent need to curb food imports; the lack of well-trained, technical personnel and sophisticated construction equipment; and the need to make full use of our human and material resources; these smallscale schemes are often very appropriate. where large projects are suitable, and there are others where only small schemes are possible. Still others may offer a chance to blend the two. In the northern part of the country a large number of seasonal streams could be tapped by constructing small storage tanks made of earthen dams and their canal systems, while in the south numerous perennial streams could be harnessed by constructing masonry THE CONFLICTING roles of the large-scale and small-scale irrigation schemes in the green revolution programme, and the economics of such schemes, are often questioned. There should in fact be no conflict between these two types of schemes, because they are complementary to and not competitive with each other. In a large, geographically varied country like Nigeria, there should be ample scope for both. There are parts of the country
