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.

This Working Paper presents methodological and substantive findings of gender-differentiated quantitative farm household surveys about smallholder’s private irrigation technology adoption in Ghana and Zambia. Focusing on three gender variables, household headship, labor provision and plot management, the paper examines adoption rates, types of technologies and gendered labor provision in female- and male-headed households; compares adoption rates on women’s own plots with overall rates; compares women’s decision-making on irrigated plots and rainfed plots; and examines impacts of targeting strategies. Findings suggest that women are proactive irrigation adopters in spite of the many obstacles they face. Removing those obstacles serves both gender equality and irrigation policies.

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.

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 womens 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 womens 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.

The report begins with an overview of the challenges on agricultural systems to make more food available and accessible and lays out the potential of irrigation to make agriculture more productive, efficient and profitable for smallholder farmers. A discussion on the potential to expand irrigation across Africa and barriers to uptake including an analysis of the inherent risks and desired outcomes of irrigation forms the next section. The report reviews the traditional and new, innovative smallscale and large-scale irrigation approaches and technologies that have been implemented in Africa, followed by an analysis of the experiences of six African countries that have been particularly innovative and successful in terms of their institutional and policy design for irrigation. The report closes by drawing some key lessons and offering nine recommendations for actions by African governments and the private sector.

Irrigated agriculture can support food and nutrition security, increase rural employment and incomes and can act as a buffer against growing climate variability and change. However, irrigation development has been slow in Africa south of the Sahara and Ghana is no exception. Out of a total potential irrigated area of close to 2 million ha, less than 20,000 ha large-scale irrigation and less than 200,000 ha of small-scale irrigation have been developed; but the latter is only an estimate. To identify entry points for accelerating small-scale irrigation development in Ghana, a national and a regional stakeholder Net-Map workshop were held in Accra and Tamale, respectively. The workshops suggest that a wide variety of actors from government, the private sector, international organizations and funders, research organizations and NGOs are involved in the diffusion of small-scale irrigation technologies. However, there are important differences between actors perceived to be key at the national and at the regional levels in northern Ghana. At the national level, diffusion of small-scale irrigation technologies is considered to be largely influenced by the Ghana Irrigation Development Authority together with a series of private sector actors focused on importation, distribution and financing of technologies. Farmers are considered to have no influence over the diffusion of small-scale irrigation, suggesting that small-scale irrigation is largely considered a supply-driven process. In northern Ghana, on the other hand, farmers are considered to be key influencers, although participants noted that much of this was potential influence, together with a larger and more diversified set of government stakeholders that are seen as regulators and possibly gatekeepers. For irrigation diffusion to successfully move from importation to distribution to benefiting smallholder farmers, all of these actors have to come together to better understand farmers’ needs and challenges. A multi-stakeholder platform could help to increase communication between farmers as the ultimate beneficiaries of small-scale irrigation technologies and the many other actors interested in supporting this process.

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.
