Available in PDF, EPUB and Kindle. Book excerpt: Despite its recent remarkable economic growth, Ethiopia remains one of the poorest countries in the world. More than 80 percent of Ethiopians obtain their livelihood from traditional low-productivity agricultural activities. Due to lack of water storage facilities and the erratic nature of rainfalls, most farmers don't have access to water to produce more than one crop per year and hence there are frequent crop failures due to droughts which have made the country one of the highest food insecure nations and receiver of food aid. It is evident that a comprehensive effort is required to increase crop and agricultural production through different intensification and productivity enhancement mechanisms and reduce rural household's food insecurity and poverty. In line with this the Government of Ethiopia and different NGO's have been promoting irrigation technology as a viable option in enhancing farm productivity and efficiency improvements. By integrating field obsei-vations, economic theory, and econometric analysis, this study assess the extent to which access to irrigation technology affects the level of technical efficiency in Gorogutu district of Eastern Ethiopia. The analysis is based on primary household-level data collected from 100 randomly selected households in 20010/11 cropping season. To analyze the effect of the technology on technical efficiency, three different Cobb-Douglas type of Stochastic Production Functions were estimated. More so, to explore different socio- economic and institutional determinants of technical efficiency in the study district, an inefficiency effect model was estimated using the one step procedure.

Download or read book Drip Irrigation for Agriculture written by Jean-Philippe Venot and published by Routledge. This book was released on 2017-07-06 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initially associated with hi-tech irrigated agriculture, drip irrigation is now being used by a much wider range of farmers in emerging and developing countries. This book documents the enthusiasm, spread and use of drip irrigation systems by smallholders but also some disappointments and disillusion faced in the global South. It explores and explains under which conditions it works, for whom and with what effects. The book deals with drip irrigation 'behind the scenes', showcasing what largely remain 'untold stories'. Most research on drip irrigation use plot-level studies to demonstrate the technology’s ability to save water or improve efficiencies and use a narrow and rather prescriptive engineering or economic language. They tend to be grounded in a firm belief in the technology and focus on the identification of ways to improve or better realize its potential. The technology also figures prominently in poverty alleviation or agricultural modernization narratives, figuring as a tool to help smallholders become more innovative, entrepreneurial and business minded. Instead of focusing on its potential, this book looks at drip irrigation-in-use, making sense of what it does from the perspectives of the farmers who use it, and of the development workers and agencies, policymakers, private companies, local craftsmen, engineers, extension agents or researchers who engage with it for a diversity of reasons and to realize a multiplicity of objectives. While anchored in a sound engineering understanding of the design and operating principles of the technology, the book extends the analysis beyond engineering and hydraulics to understand drip irrigation as a sociotechnical phenomenon that not only changes the way water is supplied to crops but also transforms agricultural farming systems and even how society is organized. The book provides field evidence from a diversity of interdisciplinary case studies in sub-Saharan Africa, the Mediterranean, Latin America, and South Asia, thus revealing some of the untold stories of drip irrigation.

Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture has played a critical role in the economic and social development of the United Statesâ€"but it is also at the root of increasing controversy. How can irrigation best make the transition into an era of increasing water scarcity? In A New Era for Irrigation, experts draw important conclusions about whether irrigation can continue to be the nation's most significant water user, what role the federal government should play, and what the irrigation industry must do to adapt to the conditions of the future. A New Era for Irrigation provides data, examples, and insightful commentary on issues such as: Growing competition for water resources. Developments in technology and science. The role of federal subsidies for crops and water. Uncertainties related to American Indian water rights issues. Concern about environmental problems. And more. The committee identifies broad forces of change and reports on how public and private institutions, scientists and technology experts, and individual irrigators have responded. The report includes detailed case studies from the Great Plains, the Pacific Northwest, California, and Florida, in both the agricultural and turfgrass sectors. The cultural transformation brought about by irrigation may be as profound as the transformation of the landscape. The committee examines major facets of this cultural perspective and explores its place in the future. A New Era for Irrigation explains how irrigation emerged in the nineteenth century, how it met the nation's goals in the twentieth century, and what role it might play in the twenty-first century. It will be important to growers, policymakers, regulators, environmentalists, water and soil scientists, water rights claimants, and interested individuals.

This book was released on 2018-06-27 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing interest in water accounting, why it is needed, what benefits it brings, and equally important, how it can be put into practice. Water accounting is not a new idea, yet it is an alarmingly simple one. It is about quantifying water resources and uses of water, much like financial accounts provide information on income and expenditure. Interest in water accounting is based on the premise that ‘We cannot plan and manage what we do not measure’ – a statement that few would disagree with. However, given the current focus on water as a precious and limiting resource, the risks of extreme floods and droughts, and water’s central role in the 2030 Agenda, it is difficult to understand why so little attention is given to water accounting and to making sure we have enough water. Indeed, estimates suggest that by 2050, if we continue with our current approach to water management, global water demand will exceed supply by over 40%, which would put at risk 45% of global GDP, 52% of the world’s population, and 40% of grain production (WWDR, 2016). This concern is supported by the World Economic Forum that consistently ranks water crises as a top global risk (WEF, 2015). Reports from South Africa (January 2018) suggesting that Cape Town may be the world’s first major city to face the prospect of running out of water following severe drought, is a timely ‘wake-up call’ for everyone to focus on accounting for water.

Download or read book The diffusion of small scale irrigation technologies in Ethiopia Stakeholder analysis using Net Map written by Bryan, Elizabeth and published by Intl Food Policy Res Inst. This book was released on 2020-07-21 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-scale irrigation (SSI) provides great benefits to farmers in terms of increased yields and profits, better food and nutrition security and greater resilience to climate shocks. Ethiopia has high potential for expanding SSI and has invested considerably in this area in recent years. Despite these investments, several challenges to further expansion of irrigation technologies remain. Different stakeholders in the country play important roles in overcoming these barriers to further scale technologies for SSI. This paper explores institutional arrangements for the diffusion of small-scale irrigation technologies by mapping the landscape of key actors involved, their interconnections, and their influence. This paper draws on an analysis of stakeholder data collected through two participatory workshops in Ethiopia, one at the national level and one at the Oromia regional level, using the Net-Map approach. Results show the dominance of government actors in the diffusion of SSI at both the national and regional levels, while most private sector and NGO actors remain in the periphery. Participants in both workshops highlighted the need for increased financing services to support the adoption of SSI and measures aimed at increasing the supply of high-quality irrigation equipment, such as modern water lifting technologies. One notable difference between the national and regional results was that at the regional level, farmers, and to some extent traders and input suppliers, were considered to be more influential in the diffusion of irrigation technologies, while they were considered marginal actors at the national level.

Book excerpt: Although over two thirds of the Earth's surface is covered by water, more than 97% is ocean water which is too salty for human use or even for irrigation. Consequently, the freshwater is only 3% and almost 1% of the available freshwater is liquid surface water that can be used directly by humans. The rest is groundwater and iced water. Yet still, freshwater is considered to be one of the most abundant resources on earth. In the agriculture sector only, over two-thirds of the available freshwater is used for irrigation. This book focuses on the technology, management and efficiency of drip irrigation.
