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 report reviews several decades of global experience in transferring management of government-run irrigation systems to farmer associations or other nongovernmental agencies in an attempt to apply the lessons of success to the African smallholder irrigation context.

Book Description
Agriculture in Africa south of the Sahara (SSA) is still largely rainfed. SSA also exhibits the lowest crop yields for major staples in the world, largely due to low use of irrigation and fertilizer. Rainfed agriculture poses growing production risks with increased climate variability and change. At the same time, smallholder irrigation in the region developed rapidly over the past decade, albeit starting from very low levels. In addition to largely demand-driven irrigation development by smallholders, there is a significant push by donors for large-scale irrigation development, as well as some push for smallholder irrigation. There has also been a long-standing debate about whether irrigation in SSA should be large scale or small scale to achieve its potential. However, given the potentially high rewards, but also high possibility of failure, the assessment of irrigation potential must go beyond large scale versus small scale to integrate concerns regarding environmental sustainability, resource use efficiency, nutrition and health impacts, and women’s empowerment. The hypothesis underlying this review paper is that how irrigation gets deployed in SSA will be decisive not only for environmental sustainability (such as deciding remaining forest cover in the region) and poverty reduction, but also for health, nutrition, and gender outcomes in the region. The focus of this paper is on the health, nutrition, and gender linkage. We find that to date, few studies have analyzed the impact of irrigation interventions on nutrition, health, and women’s empowerment, despite the large potential of irrigation to affect these important variables. Irrigation interventions may have differential effects on different members in the household and in the community, such as irrigators, non-irrigators, children, and women. Measuring and understanding such differences, followed by improving design and implementation to maximize gender, health, and nutrition outcomes, could transform irrigation programs from focusing solely on increased food production toward becoming an integral component of poverty-reduction strategies.

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
A survey of 76 public smallholder irrigation schemes in the Limpopo Province was jointly conducted by the International Water Management Institute (IWMI), Department of Agriculture, Forestry and Fisheries (DAFF), South Africa, and the Limpopo Department of Agriculture and Rural Development (LDARD), as part of the ‘Revitalization of Smallholder Irrigation in South Africa’ project. About one-third of those schemes was fully utilized; one-third partially utilized; and one-third not utilized in the winter of 2015; however, no single socioeconomic, physical, agronomic and marketing variable could explain these differences in utilization. Sale, mostly for informal markets, appeared the most important goal. Dilapidated infrastructure was the most important constraint cited by the farmers. The study recommends ways to overcome the build-neglect-rebuild syndrome, and to learn lessons from informal irrigation, which covers an area three to four times as large as public irrigation schemes in the province.

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.
