Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Private irrigation in Sub-Saharan Africa: regional Seminar on Private Sector Participation and Irrigation Expansion in Sub-Saharan Africa, Accra, Ghana, 22-26 October 2001 written by Hilmy Sally and published by IWMI. This book was released on 2011-10-21 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2023-05-08 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2006 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Improved Agricultural Water Management for Africa’s Drylands written by Christopher Ward and published by World Bank Publications. This book was released on 2016-08-23 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: D ryland regions in Sub-Saharan Africa are home to one-half of the region’s population and three-quarters of its poor. Poor both in natural resources and in assets and income, the inhabitants of drylands are highly vulnerable to droughts and other shocks. Despite a long history of interventions by governments, development agencies, and civil society organizations, there have been no sustained large-scale successes toward improving the resilience of drylands dwellers. Improved Agricultural Water Management for Africa’s Drylands describes the extent to which agricultural water management interventions in dryland regions of Sub-Saharan Africa can enhance the resilience and improve the well-being of the people living in those regions, proposes what can realistically be done to promote improved agricultural water management, and sets out how stakeholders can make those improvements. After reviewing the current status of irrigation and agricultural water management in the drylands, the authors discuss technical, economic, and institutional challenges to expanding irrigation. A model developed at the International Food Policy Research Institute is used to project the potential for irrigation development in the Sahel Region and the Horn of Africa. The modeling results show that irrigation development in the drylands can reduce vulnerability and improve the resilience of hundreds of thousands of farming households, but rainfed agriculture will continue to dominate for the foreseeable future. Fortunately, many soil and water conservation practices that can improve the productivity and ensure the sustainability of rainfed cropping systems are available. The purpose of this book is to demonstrate the potentially highly benefi cial role of water and water management in drylands agriculture in association with agronomic improvements, market growth, and infrastructure development, and to assess the technological and socioeconomic conditions and institutional policy frameworks that can remove barriers to adoption and allow wide-scale take-up of improved agricultural water management in the dryland regions of Sub-Saharan Africa.

This book was released on 2022-11-07 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study considers existing off-grid initiatives that are being implemented in support of more rapid electrification in sub-Saharan Africa. After first reviewing the successes and obstacles of commonly implemented off-grid solutions, we suggest groundwater irrigation powered via off-grid solar (OGS) systems as a productivity-focused electrification solution that could be valuable to off-grid development initiatives moving forward. This solution encourages the establishment of OGS pumping infrastructure in unelectrified areas in proximity to nonirrigated agriculture that have promising and sustainable groundwater abstraction potential. Using open-access spatial data to estimate the alignment of these resources is an important first step in determining potential study sites for on-the-ground research and pilot projects. This study focuses on applying the above approach to Ethiopia to produce a spatial layer representing areas that are recommended for further assessment of their OGS groundwater irrigation viability. We follow the spatial analysis with a projection of potential gains from investment in OGS groundwater pumping systems under different scenarios to highlight the solution’s viability with regional context. This assessment provides an initial methodology for identifying, examining, and expanding upon potential markets where OGS irrigation can become an economically viable solution.
