Book Description
Sub-Saharan Africa urgently needs to accelerate the pace of agricultural growth to improve livelihoods, ensure food security, and keep droughts from turning into famines. However, this requires the region to increase smallholder irrigation faster than its current sluggish pace. In this respect, explosive growth since the 1970s in distributed farmer-led smallholder irrigation (FLSI) in China, South Asia, and elsewhere may offer Sub-Saharan Africa better guidance than state-led centralized large irrigation projects. Proactive policy support, prominence of market players, economies of scale and scope, village-level irrigation service markets, government incentives, and subsidies on motor pumps and boreholes have all triggered and fueled rapid expansion of motor pump-driven FLSI that made famines history and countries food-secure in Asia in a short span of a decade or two. With its ample shallow groundwater resources and sparse farming areas, Sub-Saharan Africa has immense potential to grow pump-driven FLSI quickly, cost-effectively, and without risking the environmental ill effects observed in Asia and elsewhere. A "big push" to FLSI will work better than an incremental trickle because high-volume-low-margin FLSI growth generates economies of scale and scope, which are essential. Interventions by nongovernmental organizations (NGOs) are useful for demonstration and piloting innovations, but market players are best placed to achieve scale. Finally, Sub-Saharan Africa can and needs to leapfrog and build its FLSI economy around solar irrigation pumps, which are destined to disrupt FLSI globally in the years to come.

Book Description
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.

Book Description
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.

Book Description
This book provides a comprehensive analysis of the benefits and challenges of intensifying groundwater irrigation in Sub-Saharan Africa (SSA) for improving smallholder agrarian livelihoods. Only about 3% of the groundwater resources of Sub-Saharan Africa are used for irrigated agriculture despite the subcontinent’s relative abundance of groundwater. The majority of the region’s smallholders are highly dependent on seasonal dryland cropping, making them extremely vulnerable to uncertain weather patterns and droughts. Improved irrigation capabilities through sustainable groundwater development could unleash smallholder farming and make it a major driver of economic growth, poverty reduction, climate resilience, and improved food security. So, why is groundwater so underused? Tapping into groundwater requires a major shift in farming practices and it has its own challenges and requirements – smallholder access to land and finance for irrigation infrastructure and equipment, gendered and equitable adoption options. This whole list is framed in terms of what the smallholder farmers need. Hence, this should also be put in this context, supply chains, energy access, resource availability, and institutional support. The chapters in this book present a picture that is not only heterogeneous across the region, but also hold some common denominators. They serve to enrich the discourse and help better understand the barriers along the pathways toward the sustainable and transformative adoption of groundwater irrigation. The scientific information provided herein would be of interest to researchers, practitioners, decision makers and planners with interest in the region. This book was originally published as a Special Issue of Water International journal.

Book Description
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.

Book Description
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.

Book Description
If irrigated production is to make a significant contribution to food security and economic growth in Sub Saharan Africa, it will have to be re-structured across the region as a whole. This is the main conclusion of a study undertaken by FAO to analyse the drivers of demand for irrigated production in Sub-Saharan Africa (SSA). Steeply rising commercial food import bills for staple crops across SSA are indicative of the level demand that is not being met from domestic production. The increase of area under equipped/spate irrigation for the whole of Africa over the last ten years amounts to 1.27 million ha, which is equal to about 127 000 ha a year. This rate of growth has proved too low to have an impact on food import bills and buffer regional food security. However, within subregional trading groups there is scope for consolidation of market supply. Irrigated production opportunities in SSA could be realised where natural resources and markets coincide, but only through a great deal more attention to costs of production, price formation, effective water allocation mechanisms, economically efficient water use and strong, responsive institutions.
