Book Description
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.

Book Description
An entirely new agricultural technology, trickle or drip irrigation, began its development in the early 1960's. Initial progress was sporadic even though the advantages in water management with trickle systems were recognized. Operators were reluctant to use the system because of its high initial cost and questions regarding its reliability. Once the main problems were isolated and solutions developed to make the system reliable, rapid acceptance by the growers resulted. Today, trickle irrigation is being used on crops that were earlier considered to be uneconomical. This multi-purpose handbook brings together current knowledge from various engineering and scientific disciplines (crop, hydraulic, irrigation and soil sciences) needed for understanding the trickle irrigation system for crop production. The two dozen contributors are experts on the various subjects, which range from the basic to the more practical aspects of trickle irrigation. Major topics include design, operation and management - with individual chapters covering historical development, emitter construction and clogging, system design, water and salt distribution, automation, water treatment, irrigation scheduling, maintenance, fertilization and salinity.The book greatly expands the scope of research papers, reviews, extension bulletins, and updates earlier text with new information on trickle systems. A multi-disciplinary approach has been taken on a multi-faceted subject. The material contained in the book is the most comprehensive yet developed on the topic. Illustrative sample problems and solutions provide field operators and extension personnel with information needed to install and maintain trickle systems. As it is up-to-date, it is useful as a teaching and reference source for students, manufacturers and irrigation system operators as well as irrigation and crop specialists, and consultants.

Book Description
The aim of this book is quite ambitious: here, we attempt to bridge the gap between soH physicists, agronomists, horticulturists, hydraulic engineers, de signers, manufacturers and users of drip irrigation systems. We believe that progress in drip irrigation hinges on the contributions of professionals made in all related disciplines and their cooperation. The last decade has seen great development in the field of drip irrigation, al though the drip-irrigated area has not increased at the same rate as in the pre vious decade. However, our understanding of the processes involved in water and solute distribution and in plant response has increased vastly. The tools for op timal design of drip systems have improved tremendously. The main progress has been in the development and in the manufacture of sophisticated equipment; not only improved types of emitters and laterals, but also auxiliary equipment such as new filtration systems, controllers and sensors. In this book we highlight the need to maintain a proper balance between the hydraulic design of drip systems and aspects of their management and maintenance. Drip irrigation has a potential for high water use efficiency, but many well-designed systems suffer from bad management. We are indebted to the late Eshel Bresler for his contribution to our under standing of water and solute movement under drip irrigation and its appli cation to system design. Some parts of a previous publication entitled "Drip irrigation manual" authored by S. Dasberg and E.

Book Description
Increasing the efficiency of water use and enhancing agricultural water productivity at all levels of the production chains are becoming priorities in a growing number of countries. In particular, shifting to modern on-farm irrigation practices can contribute to a substantial increase in both water use efficiency and water productivity. The objective of this handbook is to provide a practical guide on the use of pressurized irrigation techniques to farmers, irrigation technicians, and extension workers in the field. In this second edition, the handbook has been considerably revised, including new chapters on low-cost drip irrigation and pipe distribution systems for smallholders.--Publisher's description.

Book Description
Readers will find that there is no universally "best" irrigation method, and that the proper method selection will depend upon the crop, climate, economics, water quality, support infrastructure, energy availability, and numerous other factors. As such, this report will remain a valuable resource each time a new irrigation need arises."--BOOK JACKET.
