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.

Irrigation Development in Africa: Lessons of Experience is a veritable encyclopedia of information on African irrigation. It describes a significant subset of the African irrigation experience, from traditional flood recession systems to large projects like Gezira and Bura.

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.

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.

Like in many parts of the world, water resources in sub-Saharan Africa (SSA) have been pivotal for human survival, economic growth, social development, and practicing certain religion and cultural ethos. However, in spite of the intrinsic values of water, its use and management in sub-Saharan Africa has not been without limitations. The demand for water resources is increasing mainly due to rapid population growth, industrialization and urbanization and dealing with water-related issues has been complex and challenging for sustainable growth. Whilst there are various efforts by national governments, non-government organizations and communities to effectively and efficiently utilize and manage water resources, there are few comprehensive studies in sub- Saharan Africa that show the impact of the efforts on poverty reduction. Although certain reports indicate that many SSA countries lack clear vision on how water use can be harnessed with pro-poor growth and how poor communities can be capacitated to use water for poverty reduction, there are little exhaustive studies that clearly show familiar and innovative water use and management interventions followed by communities, national governments and other stakeholders, and demonstrate the challenges and successes of the same. Cognizant of the knowledge gap, in 2012 OSSREA launched a research project on ordinary and innovative water use and management patterns and practices in SSA, with a view to generate new knowledge on unexploited opportunities that could enhance the contribution of water resources to poverty reduction. This anthology documents various issues including water use and management in agriculture especially in irrigation projects in Ethiopia, Kenya, Uganda and Zimbabwe; water harvesting in Kenya and Uganda; the role of local water use institutions in Ethiopia; and water source maintenance and protection in Uganda.
