Download or read book Water Productivity in Context written by Barker, R. and published by IWMI. This book was released on 2012 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we enter an era of increasing water scarcity, there is a growing interest to find ways to capture and put water to more productive uses. Substantial increases in the productivity of water in agriculture are needed to meet the demands for food and ensure environmental security, and to satisfy the demands for non-agricultural uses. However, increasing water productivity in rice-dominated agriculture is a function of the irrigation infrastructure, advances in rice-plant breeding, and the physical, institutional and socioeconomic environments. This paper first describes the potential ways in which increased water productivity can be achieved in the context of rice production in Asia. It then illustrates the ways in which the differences in the environmental context affect the ability to increase water productivity, the approaches used and the incentives to do so. This is explained using two ‘case studies’ reflecting the experiences of Taiwan and the Philippines over the past half-century.

Download or read book Groundwater Intensive Use written by Andrés Sahuquillo and published by CRC Press. This book was released on 2005-06-30 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive use of groundwater has resolved the demand for drinking water and, through irrigation, has contributed to the eradication of malnourishment in many developing countries. The spectacular worldwide increase in groundwater use in the last decades, especially in arid and semi-arid regions, has been a silent revolution carried out by millions of small farmers. In some instances, groundwater abstraction has caused problems of quality degradation, excessive drawdown of groundwater levels, land subsidence, reduction of spring and baseflows or degradation of groundwater-dependent ecosystems. Most of these problems could be anticipated, mitigated, or even avoided with more active water agencies, adequate regulations and users’ participation in management. Groundwater Intensive Use contains a selection of papers presented at a symposium held in December 2002 in Valencia, Spain. It constitutes a step forward in creating a greater worldwide awareness of the relevance of groundwater in water resources policy. The book presents new ideas and accounts of recent advances in technical, economic, legal, administrative and political issues. It addresses groundwater development to ecosystems sustainability, through different or complementary approaches. A wide series of case studies from North and South America, Europe, South Asia and North and Sub-Saharan Africa cover the various issues. These case studies represent countries with a wide diversity of social circumstances, from areas in which development is emerging, to communities with a long history of successful groundwater use.
Download or read book Multiple Uses of Water in Irrigated Areas written by International Water Management Institute and published by IWMI. This book was released on 1999 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is being transferred out of agriculture to meet the growing demand in other areas, often without an agreement of or compensation to farmers with irrigated land and water rights. Furthermore, there is a failure to recognize that irrigation systems supply water not only for the main fields, but also for domestic uses, home gardens, trees and other permanent vegetation, and livestock. Other productive uses include fishing, harvesting of aquatic plants and animals, and a variety of other enterprises such as brick making. In addition, irrigation systems can have a positive or negative effect on wildlife habitats. Thus, the withdrawal of water affects the rural household, rural economy, and the environment in a number of ways. This paper argues that to ensure efficient, equitable, and sustainable water use, to reduce poverty and improve the well-being of the community, irrigation and water resources policies need to take into account all uses and users of water within the irrigation system. The multiple uses of water in the Kirindi Oya irrigation system are examined in this paper. An interdisciplinary group of scientists have investigated a number of areas including water accounting, water quality, household water use, the valuing of water for alternative uses, and the complementarities, competition, and conflicts among uses and users.

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.
