Download or read book Drip Irrigation for Agriculture written by Jean-Philippe Venot and published by Taylor & Francis. This book was released on 2017-07-06 with total page 386 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.

Download or read book Irrigation Handbook written by Natalie Ramsey and published by Murphy & Moore Publishing. This book was released on 2021-11-16 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: The artificial techniques which are employed to apply controlled amounts of water with the objective of assisting agricultural activities fall under irrigation. The discipline finds a wide variety of applications such as maintenance of landscapes, revegetation of disturbed soils in dry areas, frost protection, suppression of weed growth, and prevention of soil consolidation. According to the method of water supply and the amount of water supplied, irrigation techniques can be classified into surface irrigation, micro irrigation, sprinkler irrigation and sub irrigation. Sprinkler irrigation can be further divided into methods using central pivot, lateral move, lawn sprinklers and hose-end sprinklers. Some of the different water sources which are used for irrigation systems are springs, wells, rivers, lakes, drainage water and treated wastewater. This book elucidates the concepts and innovative models around prospective developments with respect to irrigation. It aims to shed light on some of the unexplored aspects of irrigation. This book is appropriate for students seeking detailed information in this area as well as for experts.
Download or read book Paths to the Emerging State in Asia and Africa written by Keijiro Otsuka and published by Springer. This book was released on 2019-01-16 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC-ND license. This book addresses the issue of how a country, which was incorporated into the world economy as a periphery, could make a transition to the emerging state, capable of undertaking the task of economic development and industrialization. It offers historical and contemporary case studies of transition, as well as the international background under which such a transition was successfully made (or delayed), by combining the approaches of economic history and development economics. Its aim is to identify relevant historical contexts, that is, the ‘initial conditions’ and internal and external forces which governed the transition. It also aims to understand what current low-income developing countries require for their transition. Three economic driving forces for the transition are identified. They are: (1) labor-intensive industrialization, which offers ample employment opportunities for labor force; (2) international trade, which facilitates efficient international division of labor; and (3) agricultural development, which improves food security by increasing supply of staple foods. The book presents a bold account of each driver for the transition.

The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.
Download or read book Modernisation Strategy for National Irrigation Systems in the Philippines written by Mona Liza F. Delos Reyes and published by CRC Press. This book was released on 2017-07-12 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents documentary evidence of the insufficiency of rehabilitation works to close the gap between the irrigation service and actual area irrigated of publicly funded national irrigation systems in the Philippines. It outlines a methodology for formulating a modernisation plan for national irrigation systems with focus on the mostly ungauged, medium to small canal irrigation systems. The proposed methodology adaptively modified some known modernisation concepts and techniques and integrated them in a more holistic framework in the context of changing weather patterns and river flow regimes. It includes in-depth review of rehabilitation works; system diagnosis; revalidation of design assumptions on percolation and water supply; characterisation of system management, irrigation service and demand; and drawing up of options and a vision for the modernised irrigation systems. Central to the proposed modernisation strategy is the logical coherence among the design of physical structures, system operation and water supply so that improvements of irrigation service are possible. The book discusses the development of the proposed methodology and demonstrates its utility in two case study irrigation systems.
