The purpose of this report is to produce a review on water resource valuation issues and techniques specifically for the appraisal and negotiation of raw (as opposed to bulk or retail) water resource allocation for agricultural development projects. The review considers raw water in naturally occurring watercourses, lakes, wetlands, soil and aquifers, taking an ecosystem function perspective at a catchment scale, and takes account of the demands from irrigated and rainfed agriculture. It is hoped that the review will have particular application to developing countries where agreed methods for reconciling competing uses are often absent, but nevertheless takes account of valuation approaches that have been made in post industrial economies.

Water provides benefits as a commodity for agriculture, industry, and households, and as a public good such as fisheries habitat, water quality and recreational use. To aid in cost-benefit analysis under conditions where market determined price signals are usually unavailable, economists have developed a range of alternative valuation methods for measuring economic benefits. This volume provides the most comprehensive exposition to-date of the application of economic valuation methods to proposed water resources investments and policies. It provides a conceptual framework for valuation of both commodity and public good uses of water, addressing non-market valuation techniques appropriate to measuring public benefits - including water quality improvement, recreation, and fish habitat enhancement. The book describes the various measurement methods, illustrates how they are applied in practice, and discusses their strengths, limitations, and appropriate roles. In this second edition, all chapters have been thoroughly updated, and in particular the coverage of water markets and valuation of ecosystem services from water has been expanded. Robert Young, author of the 2005 edition, has been joined for this new edition by John Loomis, who brings additional expertise on ecosystem services and the environmental economics of water for recreational and other public good uses of water.

This book includes a set of papers from distinguished scholars who critically examine economic issues relating to the relationship between water and agriculture, with a special focus on irrigation. Employing state of the art methodologies, they address the most relevant issues in water policy. The volume offers a wide spectrum of innovative approac

A concise treatment of water-resource economics. Based upon political economy perspectives, it draws upon a range of case-studies - Third- World, developed world, and former communist countries - to cover many issues. There is guidance on

The purpose of this book is to develop a general economic model which integrates the quantity and quality issues of water resource management and to provide, along with a detailed criticism of the policy instruments now in use, alternative proposals concerning the efficient allocation and distribution of water. In particular we treat water as a multi-product commodity where the market plays a major role in determining water quality-discriminant pricing and its value to the user. We examine the process of moving from administrative allocation and regulation to privatization of the water industry as the key element in promoting effective competition and in providing economic incentives for greater efficiency. Water quantity and quality, considered independently of each other, have been the subject of numerous studies during the last twenty years. Let us recall briefly the most outstanding among them. A variety of models have been constructed concerning the optimal scheduling and sequence of water-supply projects: dynamic programming for solving multi-bjective functions in water resource development; planning models for coordinating regional water-resource supply and demand, etc. Other studies have devised water-quality management models, including multi-period design of regional or municipal wastewater systems; cost-allocation methods to induce effluent dischargers to participate in regional water systems; models to predict the quality of effluent (in particular, whether it meets certain established standards); models for finding optimal waste-removal policies at each of the polluting sources, and so on.

This book arose out of a paper that I wrote for the World Bank at the request of Ariel Dinar, the editor for the series in which this volume appears. I began that paper by pointing to the growing importance of demand-side considerations in water resources: "The provision of potable water is one of government's oldest functions with evidence of this activity stretching back thousands of years. During much of that time, water demands were taken as exogenously given and the principle task of authorities was defined as an engineering one: how to supply a given quantity of water at least cost. In recent years, however, concerns have arisen from observations of excessive water use, degraded water quality and continued inadequate service for many, especially the very poor. As a result of these and other concerns, there is a growing effort to view water resource allocation from a perspective that incorporates consumers' preferences along with supply constraints into management plans. " (Renzetti, 2000, p. 123). The purpose of this volume is to examine, in greater detail than was possible in that article, what is known regarding the economic characteristics of the demand for water. Thus, this book is meant to be an extended critical review of the state of the art.

Because water in the United State has not been traded in markets, there is no meaningful estimate of what it would cost if it were traded. But failing to establish ground water's value--for in situ uses such as sustaining wetlands as well as for extractive uses such as agriculture--will lead to continued overuse and degradation of the nation's aquifers. In Valuing Ground Water an interdisciplinary committee integrates the latest economic, legal, and physical knowledge about ground water and methods for valuing this resource, making it comprehensible to decisionmakers involved in Superfund cleanup efforts, local wellhead protection programs, water allocation, and other water-related management issues. Using the concept of total economic value, this volume provides a framework for calculating the economic value of ground water and evaluating tradeoffs between competing uses of it. Included are seven case studies where ground-water valuation has been or could be used in decisionmaking. The committee examines trends in ground-water management, factors that contribute to its value, and issues surrounding ground-water allocation and legal rights to its use. The book discusses economic valuation of natural resources and reviews several valuation methods. Presenting conclusions, recommendations, and research priorities, Valuing Ground Water will be of interest to those concerned about ground-water issues: policymakers, regulators, economists, attorneys, researchers, resource managers, and environmental advocates.

Most of the books published previously in the field of water resource eco nomics focus on particular aspects of water economics such as institutions, pricing or water markets, but none of them have given particular attention to methodological questions. However, the applied methodology within economic research has made some remarkable advances over the last 10-20 years. Some of these advances are of particular interest to the field of water economics. Therefore, we think that a book that focusing on methodological advances within the field of water resource economics and showing how these advances can be applied in economic analysis of water issues makes a nice complement to the existing literature in this field. We identified five areas where we consider the methodological advances to be of particular importance: 1) asymmetric information and game theory, 2) un certainty, 3) space, 4) water quality and 5) production and technology adoption. The selected papers for the book fall entirely within these categories. The book ''Frontiers in Water Resource Economics" draws to a great extent on papers which were presented at the 7^^ Conference of the International Water and Re source Economics Consortium, June 3-5,2001 held in Girona, Catalonia, Spain, This conference was jointly organized with the 4^^ Conference of Environmen tal and Resource Economics by the Department of Economics, University of Girona.

Chapters include: "Water prices and rates for residential use", "Uncertainty and risk in supply and demand of water resources", and "Floods and droughts and the role of dams".
