In low- and middle-income countries, people need water for drinking, personal hygiene and other domestic use. But they also use it for livestock, horticulture, irrigation, fisheries, brickmaking, and other small-scale enterprises. Multiple-use water services (MUS) are best suited to meeting people’s needs. However, most water services are designed only for domestic water or only for agriculture, and fail to reflect its real-life use. The action research project ‘Models for implementing multiple-use water supply systems for enhanced land and water productivity, rural livelihoods and gender equity’ developed case studies in eight countries (Bolivia, Colombia, Ethiopia, India, Nepal, South Africa, Thailand and Zimbabwe) involving 150 institutions. The project analysed two models: homestead-scale and community-scale MUS and developed a ‘multiple-use water ladder' to show how better livelihoods flow from increased access to water. This book shows how livelihoods act as the main driver for water services and how access to water is determined by sustainable water resources, appropriate technologies and equitable ways of managing communal systems. Climbing the water ladder requires a small fraction of total water resources, yet has the potential to help people climb out of poverty. Local government can be the pivot to make this happen. But, it needs support to implement its mandate to meet multiple-use demand and to become more accountable to people in communities.

Many farms in tropical countries suffer from droughts in the dry season and sometimes even in the rainy season. In order to significantly increase the capacity to store water, the grassroots Farmer Wisdom movement in Northeast Thailand innovated pond construction on homesteads. This Working Paper first documents how pond water is mainly used to irrigate crops and fruit trees, and is also used for livestock or fish, and for domestic uses, even if ample piped water is available. Households were also found to harvest rainwater from roofs; take water from canals and streams; lift water manually from shallow wells and with electric pumps from deep wells; channel run-off from roads to paddy fields; use precipitation as green water on fields; and buy bottled water. Most households combine at least six of these nine water sources. The second part describes scenarios and some outcomes of a new simulation model, BoNam. This model provides guidelines for the optimal size and site of such ponds according to biophysical factors (weather, soil and crops), socioeconomic factors (prices, availability of labor and off-farm income) and household aspirations.

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.
