The limit of rain fed agriculture is one of the major causes for poor agricultural performance in Sub-Saharan Africa, due to the prevailing climatic conditions. If these challenges are further juxtaposed with the climate change projections, irrigation then becomes a key solution to such agricultural challenges of changing rainfall amounts and seasonal rainfall variability in the Upper East region of Ghana. The extreme variability in rainfall, long dry seasons and recurrent droughts, floods and dry spells pose key challenges to food production and has resulted in hunger and poverty in the Upper East Region of Ghana. The practice of irrigated agriculture remains a key solution to hunger and poverty reduction in this area. As a result the area has seen a significant upscaling of irrigation using shallow groundwater and surface water with appropriate technologies within the past 15 years. This study used a gendered approach to assess how poverty alleviation through the use of shallow wells and riverine dugouts have differential access for men and women. Whilst it is often argued that water based interventions to reduce poverty need to be gender sensitive this research looked at whether the underground water irrigation technologies are accessible to both men and women. This paper is part of a hydraulic rights creation project in the broader Volta Basin. This study looked at how both men and women appropriate water resources for their benefit. This study concludes that shallow ground water technologies have to be grounded within the gendered production systems and tenurial arrangements which largely determine whether one benefits from water extraction technologies or not. In rural Africa where the majority of the poor households are de facto or de jure female headed, this paper proposes mechanisms for empowering women to benefit from ground water based irrigation.

For agriculture there is a continuum of water storage options, ranging from groundwater aquifers, soil water, natural wetlands and small ponds and tanks to large reservoirs. In any situation each of these has its own niche in terms of technical feasibility, socioeconomic sustainability and impact on public health and the environment. Planning storage requires insight into impending needs and also a good understanding of what already exists and what was, and was not, successful, in the past. This report provides an inventory of existing and prospective water storage in the Ghanaian Volta and the Ethiopian Blue Nile basins. It provides as much quantitative data as possible, but highlights both the dearth of readily available information and the lack of integrated planning of storage in both basins. Recommendations are made for improved planning in the future.

Global reports and major funding agencies herald the comeback of agriculture on the international development agenda as a means of achieving the Millenium Development Goals. Within this renewed interest, irrigation is presented as pivotal to increasing food production and alleviating poverty. This is especially the case in sub-Saharan Africa, where macro indicators point to an underdeveloped and underperforming agriculturecum-irrigation sector. While large dam projects are still prevalent, small-scale irrigation has also become the focus of increased attention from researchers, national decisionmakers, and the international development community. Indeed, small-scale irrigation fits well within the development narrative of participation. This paper engages with such a view. It uses the example of small reservoirs in northern Ghana to highlight that small scale irrigation projects are, firstly, based on narrow visions of the ‘commons’ and participation that rarely consider the experiences and perceptions of local populations; secondly do not account for the de-facto institutional “bricolage” and the diverse land and water claims that they contribute to shape; thirdly, and in ontrast to the new vocabulary of development, continue to regard intended beneficiaries as ‘recipients’ rather than participants with agency; and, finally, largely ignore broader institutional issues that characterize the water sector in the country. Further investments and reforms are said to be the remedy. These are unlikely to succeed, so long as they adhere to a narrowly-defined notion of development. This paper calls for an approach that which acknowledges the multiple claims and uses of natural resources, and which recognizes that projects contribute to shaping new meanings of space and relationships to environments, whose fairness depends on the vantage point considered.

This report analyses environmental and health impacts arising from agricultural water development in sub-Saharan Africa and recommends ways to increase the sustainability of investments in irrigation by taking into account health and environmental concerns. In many places in the region irrigation is a key means of enhancing productivity that can reduce poverty and improve livelihoods. However, failure to adequately foresee, plan and manage the negative environmental and health impacts arising from irrigation undermines the sustainability of many projects and may worsen poverty.This report is not intended as a compendium of data on environmental and health issues pertaining to agricultural water development. Rather it seeks to provide an overview and framework for understanding policy and programming issues to tackle these issues.

This paper focuses on enhancing returns on investments in agricultural water through effective integration of livestock production. It suggests that multi-sectoral approaches to investment in water, soil, crop and livestock will have greater development impact and profitability than developing water and livestock independently in the same areas.

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.

Water, energy, and food are linked in intricate ways in irrigated agriculture and understanding the interplay of these components is crucial for sustainable and profitable crop production, particularly in smallholder setting such as in sub-Saharan Africa. This study evaluates water-energy-food linkages, engineering and economic performance, irrigation decision making, and challenges faced around water management in a community-based mechanized irrigation scheme in Rwanda. The research is the first to analyze such as scheme, which uses technology typically used by large farmers in a smallholder setting. The study investigates the variation in water requirements and the relationship and impacts of this variability on crop yield for the crops grown in the scheme: maize, French beans, and dry beans. Observed irrigation decision-making analyses demonstrate a lack of irrigation planning during growth stages and significant field-to-field variation in irrigation; this is linked to yield reduction in major crops. Results suggest that farmers irrigated only 31% of modeled irrigation water in dry beans and 27% of modeled irrigation water in maize. An econometric model assessment is used to understand the relationship between yield and energy inputs. A related policy analysis considers the impacts of changes in crop and water management on field-level profits and system-level financial sustainability. This study has implications for understanding irrigation policies in the context of the water-energy-food nexus and decision-making in Sub-Saharan Africa.
