Book excerpt: Smallholder irrigation systems–where farm sizes generally range from a fraction of a hectare to 10 hectares–pose special management problems, especially where the water available for irrigation is frequently less than the demand. The intensity of system adjustments required to meet individual farmer demands, and the administrative complexity of measuring and accounting water deliveries have generally proven excessive when attempting to meet “on demand” schedules, resulting in chaos (often characterized by illegal tampering with infrastructure, and vast differences of water use intensity at different locations in the system). The alternative–provision of a simple service, based on proportional sharing of available supplies on the basis of landholdings–has been resilient for many years over vast areas. The approach is based on a clear delineation between the part of the irrigation system that is actively managed (at various flow rates and water levels) and the part of the system that operates either at full supply level (with proportional division of water down to the level at which farmers rotate among their individual farms), or is completely shut. This operational design is known as a “structured” system, and has well-defined hydraulic characteristics, simplifying operation and management, in turn allowing a clearer definition of water entitlements and the responsibilities of agency staff and farmers. The approach is particularly suited to areas where water is scarce and discipline is needed to ration water among users. An additional benefit, which has been demonstrated in modeling studies using a well–proven model relating to water and yield, is that the productivity of water (which is more important than the more traditional productivity of land when water is scarce) is substantially increased when deficit irrigation is practiced–a widely observed and predictable response to rationed water supplies. Structured systems are most suited where water is scarce, clear definition of water entitlements is needed, management capacity is limited, and investment resources are limited. The approach to determining critical aspects of a structured system design is described in this report.

Available in PDF, EPUB and Kindle. Book excerpt: 'A unique and significant longitudinal study of irrigation intervention in FMIS in Nepal that revives important debates on how irrigation management evolves and how this can be investigated. This concise and accessible book can inform and challenge agencies and donors to reflect on policies and researchers to argue further the study of collective action and political theory in irrigation management.' – Linden Vincent, Wageningen University, The Netherlands 'Improving Irrigation in Asia by Elinor Ostrom and colleagues is grounded in intimate detail on water management experience in Nepal while being informed by broadly-applicable concepts and behavioral theories. It greatly advances our understanding of management options and effects. As the water resources available for agriculture become more limited and unreliable, the efficiency and productivity with which irrigation water is used must be increased. While better technology can assist in this quest, the greatest potential gains lie in the social and organizational domains.' – Norman Uphoff, Cornell University, US 'Governance of irrigation systems is complex, needing social, technical and financial actions that support farming. Few people have as much knowledge of self-governing irrigation systems as these authors, and few countries have as many of these systems as Nepal. Lessons from these small irrigation systems can be adapted to much larger units, and to other kinds of activity. External assistance on a modest scale could generate practical benefit, by encouraging self-reliance in communities.' – Charles Abernethy, International Irrigation Management Institute, Colombo (1987–94) and Asian Institute of Technology, Thailand (1996–99) Improving Irrigation in Asia is based on a longitudinal study over two decades on innovative intervention for sustained performance of irrigation systems. The work identifies key factors that can help explain the performance of interventions, and explicates lessons for resource management and the management of development assistance. In 1985, the Water and Energy Commission Secretariat of Nepal and the International Irrigation Management Institute developed an ingenious intervention program for nineteen irrigation systems located in the middle hills of Nepal in an attempt to overcome the prevailing 'best-practices' traps, in regard to assisting irrigation systems. This book highlights the innovativeness of the project lay in its provision of ample opportunities for farmers to make decisions regarding the operation of the irrigation system based on their local knowledge and creativity. The authors of this work, Elinor Ostrom, Wai Fung Lam, Prachanda Pradhan and Ganesh P. Shivakoti provide detailed analysis of these interventions and support the conclusion that farmers can build on an innovative intervention that not only provides physical improvements but also enhances farmers' problem-solving capacity. They argue that to achieve sustainable improvements in performance, the farmers themselves need to engage in collective action over time and support local entrepreneurs who provide leadership and stimulate adjustments to change. Providing practical policy solutions, this study will prove a fascinating and invaluable read for academics and scholars of development studies, resource management, and irrigation studies, as well as development specialists in international agencies, policymakers in governments and international donor agencies.

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: Addresses the issue of international competitiveness from the perspective of developing countries, which must exploit the opportunities offered by international trade and the extraordinarily rapid technological progress of recent years. The book's central message is that while sound macroeconomic management is crucial for achieving a sustained rise in living standards, it is an economy's ability to generate and manage technological change that ultimately determines its success in the world market and the pace at which it grows.
