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 uses 314 irrigation projects implemented from 1960-2000 in six regions worldwide to identify: (1) whether the perception of high cost of irrigation projects in SSA can be empirically supported; (2) what factors determine the costs and performance of irrigation projects; and (3) whether there are cheaper and better performing irrigation investments for SSA. This study shows that the popular view that African irrigation projects are prohibitively expensive is not tenable, and demonstrates that there are viable investment options for irrigation development in SSA.

Declining productivity of agricultural soils in Northeast Thailand is a challenge facing land managers and farmers. A program was initiated in 2002 to investigate the potential role of incorporating clay-based materials into degraded soils as a means of enhancing productivity. This research report attempts to provide an ex-post assessment of the field level impact and economic viability of this approach, using the empirically derived estimates of the average income impacts that the application of bentonite or clay technology has generated among farm communities in Northeast Thailand. From an exclusive IWMI perspective, the impact evaluation suggests that the program has a net present value (NPV) of US$0.41 million with a benefit-cost ratio (BCR) of 2.44 for the sample, and a NPV of US$21 million with a BCR of 75 for the region.

This study aims to systematically establish whether costs of irrigation projects in SSA are truly high, determine the factors which influence costs and recommend cost-reducing options in order make irrigation investments in SSA more attractive. The study analyzes 314 irrigation projects implemented from 1967 to 2003 in 50 countries in Africa, Asia, and Latin America funded (or assisted) by the World Bank, African Development Bank and the International Fund for Agriculture Development. The sample includes “irrigation” projects, irrigation development with power generation (“irrigation with power”) projects, and irrigation component in multi-sectoral projects (MSPs). For the latter two types of project, only the cost of the irrigation component was included in the analyses. The study distinguishes projects according to purpose (ranging from purely new construction to purely rehabilitation), type of irrigation system (river diversion, reservoir-based, tank, river/groundwater-lift, and largely drainage or flood control), mode of O&M (government managed, jointly managed, farmer-managed), and major crops irrigated. All data are obtained from project completion (PCRs) and performance audit reports (PPARs) complemented with information from staff appraisal reports. Unit irrigation costs and project performance measured by economic internal rates of return are actual figures reported in PPARs or PCRs. This report examines whether the difference in unit costs in sub-Saharan Africa compared with other regions is significant, and identifies the key determinants of unit investment costs and performance of irrigation projects. It makes three important contributions: (1) it confirms some earlier findings about irrigation projects; (2) it disproves some popularly-held notions and incorrect perceptions about unit costs and performance of irrigation projects in sub-Saharan Africa; and (3) it provides empirical support to some existing irrigation investment policies and programs and a basis for reconsideration of others and introduction of new ones. The report presents recommendations for formulating better irrigation projects and a clear investment direction in agricultural water in sub-Saharan Africa.
