Book Description
Over the past decade, we have witnessed a growing scarcity of and competition for water around the world. As the demand for water for domestic, municipal, industrial, and environmental purposes rises in the future, less water will be available for agriculture. But the potentials for new water resource development projects and expanding irrigated area are limited. We must therefore find ways to increase the productivity of water used for irrigation. This paper reviews the literature on irrigation efficiency and on the potential for increasing the productivity of water in rice-based systems. It stresses the continuing confusion over the concepts of irrigation efficiency and water productivity. It identifies the reasons for the wide gap between water requirement and actual water input (both irrigation diversions and rainfall) in irrigated rice production systems and discusses potential opportunities for increasing water productivity both on-farm and at the system level. Based on the reported low farm and system level irrigation efficiencies, the potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs, and environmental aspects of alternative interventions are also lacking. This paper emphasizes the need to measure the productivity of water at farm, system, and basin levels, and to understand how the productivity at one level relates to the productivity at another. Without water balance studies to measure productivity at these different scales, it is not possible to identify the potential economic benefits of alternative interventions and the most appropriate strategies for increasing irrigation water p productivity in rice-based systems.

Book Description
This book presents a comprehensive account of problems and issues associates with command area development. It is a longitudinal study where the same set of villages and households were studied at two points of time with a gap of eight years. The main thrust of the study, among other things, is on on-farm development, water management, agricultural extension and the locational advantages of a farm plot in ensuring timely and adequate supply of water.

Book Description
This book tells the story of development studies in practice over the last fifty years through the work of one remarkable individual, Robert Chambers. His work has taken him from being a colonial officer in Kenya through training and managing large rural development projects to a fundamental critique of top-down development and the championing of participatory approaches. The contributors eloquently demonstrate how he has been at the centre of major shifts in development thinking and practice over this period, popularising terms that are now at the centre of the development lexicon such as vulnerability, multi-dimensional poverty, sustainable livelihoods and 'farmer first'. Robert Chambers played a major role in the massive growth in participatory approaches to development, and particularly the application of participatory methods in development research and appraisal. This has led to fundamental challenges to development practice, ranging from approaches to monitoring and evaluation to institutional learning and professional training. There is probably no-one who has had more influence on approaches to development in the past decades. Revolutionizing Development offers a unique overview of these contributions in thirty-two concise chapters from authors who have been intimately involved as collaborators, critics and colleagues of Robert Chambers.

Book Description
Eminent economists and development experts focus on a number of concerns that are currently the major preoccupation of development economists, policymakers, and practitioners. The issues addressed in this collection center on strategies to eradicate poverty, reduce inequality, and deal effectively with problems of management and the utilization of land and water resources. The contributors analyze the issues in the context of past experience, the present international setting, and possible alternative strategies for the future, and consider, as well, theoretical and methodological concerns.
