Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2012 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report investigates the dynamics of one of the most common agricultural water management practices of sub-Saharan Africa, i.e., small reservoirs. Small reservoirs dam permanent or temporary river flows and support multiple livelihood activities (livestock watering, crop cultivation, fisheries, small handicrafts, etc.) while providing water-related ecosystem services (soil and water conservation, flood and drought mitigation, etc.). Gathering evidence from four sub-Saharan countries, Burkina Faso, Ghana, Ethiopia and Zambia, this report calls for revisiting our understanding and assessment of the costs, performance and institutions for the management of small reservoirs. A more holistic analytical approach is the first step towards an integrative governance framework. This, in turn, holds the promise of sustainable management of small reservoirs.

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.

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 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.

Download or read book Water Harvesting in Sub Saharan Africa written by William Critchley and published by Routledge. This book was released on 2013-01-04 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture in Sub-Saharan Africa is constrained by highly variable rainfall, frequent drought and low water productivity. There is an urgent need, heightened by climate change, for appropriate technologies to address this problem through managing and increasing the quantity of water on farmers’ fields – water harvesting. This book defines water harvesting as a set of approaches which occupy an intermediate position along the water-management spectrum extending from in situ moisture conservation to irrigated agriculture. They generally comprise small-scale systems that induce, collect, store and make use of local surface runoff for agriculture. The authors review development experience and set out the state of the art of water harvesting for crop production and other benefits in Sub-Saharan Africa. This includes an assessment of water harvesting schemes that were initiated two or three decades ago when interest was stimulated by the droughts of the 1970s and 1980s. These provide lessons to promote sustainable development of dryland agriculture in the face of changing environmental conditions. Case studies from eight countries across Sub-Saharan Africa provide the evidence base. Each follows a similar format and is based on assessments conducted in collaboration with in-country partners, with a focus on attempts to promote adoption of water harvesting, both horizontally (spread) and vertically (institutionalization). Introductory cross-cutting chapters as well as an analytical conclusion are also included.

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.
