'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.

This book is an outcome from the International Expo 'Water and Sustainable Development' held in Zaragoza (Spain) in 2008. Support from the Spanish Ministry of Environment, Caja Rioja, Government of Aragon, and the World Bank is acknowledged. 'Few resources will play a more important role in shaping our economic future, or face more daunting challenges, than water. This internationally acclaimed team of experts has produced a first-rate volume that is full of intriguing, practical ideas for meeting those challenges in a rich variety of institutional settings.' Tom Tietenberg, Mitchell Family Professor of Economics, Emeritus, Colby College, USA 'This volume brings together two critical but interrelated dimensions of water challenge, i.e. water pollution, particularly from non-point sources, and water conservation. The editors are well known experts on the subject as are the contributors.' R. Maria Saleth, International Water Management Institute, Sri Lanka and Associate Editor, Water Policy 'The profound contribution of this volume is that it brings together various economic concepts and policy dilemmas regarding water shortages, non-point source pollution, efficiency of water use and irrigation technology. Recommended reading for anyone working in the area of water management.' Henk Folmer, University of Groningen and Wageningen University, The Netherlands As countries face deteriorating water and environmental quality as well as water shortages, pollution control and the efficiency of water use become of paramount importance. Agriculture is one of the main non-point polluters of water bodies and irrigation for agriculture is one of the main consumers of water. While it is very hard to regulate pollution from agriculture, attempts have been made via economic and command and control instruments, and also through investments in technologies and ecosystems recovery. Coping with non-point pollution takes the form of both policy intervention and technology development. Likewise it is recognized that irrigation efficiency varies across countries, influenced by both technology and supporting adoption policies. Countries that lead in irrigation technology and supporting policies have certain traits in common. They face very high scarcity and are pushed to find innovative solutions, both technical and policy related. The recent multibillion investments in irrigation technologies in Spain, and similar proposals in Australia, for example, highlight the potential of irrigation technologies to cope with scarcity and water quality degradation. This book reviews all of the above issues, presents experiences in selected countries, and assesses the degree of success of alternative policies for coping with non-point water pollution and improving irrigation efficiency.

This volume covers a selection of important novel technological interventions in dairy science, from the physical properties of milk and other milk products to nonthermal processing of milk. It also discusses safety methods in dairy science, which includes cleaning-in-place and techniques to determine adulteration in milk. Milk is a perishable commodity, and being rich in nutrients, it acts as the perfect substrate for the growth of microflora (sometimes dangerous for consumption). To reduce this, different thermal and nonthermal techniques are used. Thermal treatments are common techniques used for extending the shelf life of milk, such as, for example, pasteurization, sterilization, and UHT, but loss of nutrients is a concern associated with these treatments. Nonthermal treatments like high-pressure processing, pulse electric field, ultra-sonication, and irradiation are also explored in the processing of milk to minimize the loss of nutrients as compared to thermal treatment. Post-process contamination is also a major factor that can affect the shelf life of milk, and safe packaging plays an important role when the milk and milk products are stored at refrigeration or ambient temperature. Many advances in these dairy technologies are presented in this informative volume. Technological Interventions in Dairy Science: Innovative Approaches in Processing, Preservation, and Analysis of Milk Products will prove valuable for industrial professionals, scientists, regulatory personnel, consultants, academics, students and field-related personnel. The book also attempts to bridge the gap between research and industrial application of recent techniques.
