This book was released on 2007 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Treadle pump (TP) technology has been promoted by Enterprise Works Worldwide (EWW) as an alternative to the traditional rope and bucket irrigation that is necessary to overcome the challenge of uncertain and inadequate rainfall for agricultural production. The aim is to improve output, increase incomes and reduce poverty among farm households. This study examines the strategies used for dissemination of the TP and the dynamics of its adoption and impacts, with a special focus on poverty reduction. The results of the study reveal that time and labor savings for irrigation, increased size of irrigated areas and lack of fuel requirements are the attractive features of the TP for those who adopt it. Adoption of TP increases land and labor productivities; and also net farm incomes. The study also demonstrates that adoption of the TP reduces poverty.

Download or read book The Water Buffalo written by Abraham Baldwin McKay and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis reports on the development a low cost and mass-producible bicycle powered irrigation pump for small-scale (100–1,000 m2 plot) African farmers. The pump is intended to be made and distributed by World Bicycle Relief’s Buffalo Bikes program. This project’s process is divided into three parts: an investigation into the user needs, quantitative testing of a prototype pump’s power and efficiency, and the redesign of the pump for manufacturing. In order to clarify the user needs, I conducted in-depth interviews and informal demonstrations with small-scale farmers in Kenya. I learned of additional user requirements; for example, that the pump must be usable by children. I also learned of critical problems with the early design; for example, that air leaks on the suction side of the pump will hobble its performance. Though imperfect, the limited success of the trials verified the viability of a bicycle irrigation pump in the target market. To quantify the effectiveness of a centrifugal bicycle powered pump, I measured the pump’s water flow at various input power levels and outlet heights (vertical heads). The efficiency of the pump system ([eta] ≈ 55%) approached the claimed manufacturer’s maximum efficiency of [eta] ≈ 66%. I then compared the bicycle pump to two other human powered pumps, both of which use a treadle pumping style. The bicycle system pumps water at similar or possibly higher flows than the tested treadle pumps. Friction calculations additionally revealed that at fast flow rates of 1 liter per second (16 gallons per minute), hoses with a 1 inch diameter (25.4 mm) have significant friction losses, while 1.5 inch (38.1 mm) hoses have negligible friction losses.Based on the interviews and efficiency tests, I redesigned the pump and gearbox to be made of plastic and to address the main issues identified in the field. The pump-to-hose attachments are designed to reduce air leaks, reduce tipping, and simplify the pump’s setup. The form of the gearbox is designed without overhangs so that it can be manufactured by casting. By creating an inexpensive irrigation method, I hope to empower small-scale African farmers to lift themselves into prosperity.

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: The Southern African Development Community (SADC) and its Member States are making renewed efforts to revive agriculture in the region. Given that much of it is water-stressed, appropriate and sustainable land and water management practices are vital to achieving this objective. Recognising this, SADC's Land and Water Management Applied Research and Training Programme has convened two scientific symposiums. Held in Lilongwe, Malawi, in February 2006, the inaugural symposium brought together practitioners from 10 participating SADC countries to deliberate on land and water management for sustainable agriculture, and discuss how the most recent research and development advances in land and water management might be made more relevant to policymakers as well as the region's small-scale farmers. The edited contributions to this first symposium appear in this volume. The second symposium was held in Gaborone, Botswana, in February 2007, and brought together regional experts to discuss opportunities for improving water use and water use efficiency in agriculture in semi-arid and arid areas. The edited contributions to the second symposium appear in a companion volume entitled Land and Water Management in Southern Africa: Towards Better Water Use in Agriculture in Semi-Arid and Arid Areas (AISA 2008). It is hoped that these two volumes will help to disseminate regional expertise on land and water management to a wider audience, thus helping policy-makers and others to strengthen the agricultural sector in the region, and, in so doing, improve its food security and the wellbeing of its people.

Available in PDF, EPUB and Kindle. Book excerpt: Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

This book was released on 2005 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines ways to increase food security, reduce poverty and achieve economic growth in sub-Saharan Africa with ‘water’ through increased participation of the private sector and publicprivatepartnerships. This report is a summary of the findings from a review of the literature and critical analysis thereof. The ‘private sector’ includes all farmers, farm households, and agriculture-based micro, small and medium enterprises (MSMEs). That is: all entities involved in crop, livestock and fish production and marketing, in post-harvest activities and food processing, and in supply chains for the goods, services and information used in the process. The study examines different types of agricultural water development and management. These include smallholder subsistence farming, cultivation of profit-oriented high-value crops, and peri-urban agriculture, as well as successful examples of private sector involvement in various functions or processes, including planning, design, construction, operations and maintenance. The spotlight on ‘water’ does not imply that other factors, such as off farm employment, market development and education, are unimportant.

This book was released on 2016-08-23 with total page 177 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.

Download or read book Is ‘Social Cooperation’ for Traditional Irrigation, while ‘Technology’ is for Motor Pump Irrigation? written by Mengistu Dessalegn and published by IWMI. This book was released on 2015-02-18 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on a case study in Ethiopia, this paper shows that while farmers understand the social nature of community-managed irrigation, they share a narrow understanding of pump irrigation with policymakers as being primarily ‘technical’. They perceive pumps as liberating them from the ‘social’ limitations of traditional communal irrigation. However, the rapid expansion of pump irrigation is leading to increasing competition and conflict over limited water resources. We analyze the wider implications for Africa of this lack of visibility of the social dimension of pump irrigation, and offer suggestions for future policy and applied research to address the problem before it becomes a widespread crisis.
