This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

Only 4 percent of arable land in sub-Saharan Africa is irrigated, using just 2 percent of the available water resources. Furthermore, 18 percent of the area equipped for irrigation is not utilized at all and the intensity of use varies between 50 percent and 80 percent. This highlights the huge potential available for intensifying and expanding irrigated area, provided that the investments required can be successfully mobilized. However, it must be noted that if investments in irrigation are to yield satisfactory returns, investments must also be made in a series of related activities. Current global figures for the amount of private investment in irrigation confirm that good returns can indeed be achieved. Prospects for sub-Saharan Africa would be far more favorable if public development assistance, particularly foreign direct investments, did not show declining trends.

Weaknesses in planning and implementation (P&I) have been identified as one of the main reasons for the disappointing results of agricultural water development and management projects. Based on a review and critical analysis of experiences and case studies in sub-Saharan Africa, this studycomponent proposes practical ways of improving performance related to planning and implementation and thereby enhancing the returns to investments in agricultural water.

High irrigation investment costs together with declining world prices for food and the failures of a number of high profile past irrigation projects are the main reasons for the reluctance of development agencies and governments in sub-Saharan Africa to invest more resources in irrigation. This study aims to systematically establish whether costs of irrigation projects in sub-Saharan Africa are truly high, determine the factors which influence costs and performance of irrigation projects, and recommend cost-reducing and performance-enhancing options to make irrigation investments in the region more attractive. It analyzes 314 irrigation projects implemented from 1967 to 2003 in 50 countries in Africa, Asia, and Latin America funded by the World Bank, African Development Bank and the International Fund for Agricultural Development.

This paper provides an overview of innovative options for developing and using water for food production in sub-Saharan Africa (SSA) in light of the growing scarcity and competition for water resources. These options include rainwater harvesting, selective development of wetlands for agriculture, exploitation of shallow groundwater, and recycling urban waste. The options are largely based on low-cost individualized technologies, which lend themselves to private-sector promotion.Water-demand management approaches are also discussed.
