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.

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.

Gibbons examines the water supply problem through five case studies. The problems faced by these regions and the methods suggested to overcome them provide excellent models for the entire United States. The case studies---typically, expanding supplies---but economic efficiency principles lead to emphasizing managing the demand. In many cases, this means reducing demand by raising prices.

Ecosystem services can be broadly defined as the aspects of ecosystems that provide benefits to people. This book provides guidance on the valuation of ecosystem services, using the case of multifunctional wetlands to illustrate and make recommendations regarding the methods and techniques that can be applied to appraise management options. It provides a review of ecosystem service valuation rationale, including its importance from both a policy and project appraisal perspective, and a useful reference when considering policy and appraisal of ecosystem management options. It shows how legal obligations and other high-level management targets should be taken into account in valuation exercises, thus giving important policy context to the management options. The authors set out what they call an Ecosystem Services Approach to the full appraisal of the role of ecosystem services in the economy and society. Although concentrating on wetlands, the approaches suggested provide an assessment framework that can be applied to other types of ecosystem assets.

This book provides an insightful and critical assessment of the state of Canadian water governance and policy. It adopts a multidisciplinary variety of perspectives and considers local, basin, provincial and national scales. Canada’s leading authorities from the social sciences, life and natural sciences address pressing water issues in a non-technical language, making them accessible to a wide audience. Even though Canada is seen as a water-rich country, with 7% of the world’s reliable flow of freshwater and many of the world’s largest rivers, the country nevertheless faces a number of significant water-related challenges, stemming in part from supply-demand imbalances but also a range of water quality issues. Against the backdrop of a water policy landscape that has changed significantly in recent years, this book therefore seeks to examine water-related issues that are not only important for the future of Canadian water management but also provide insights into transboundary management, non-market valuation of water, decentralized governance methods, the growing importance of the role of First Nations peoples, and other topics in water management that are vital to many jurisdictions globally. The book also presents forward-looking approaches such as resilience theory and geomatics to shed light on emerging water issues. Researchers, students and those directly involved in the management of Canadian waters will find this book a valuable source of insight. In addition, this book will appeal to policy analysts, people concerned about Canadian water resources specifically as well as global water issues.

This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.

Until recently, there has been general agreement that improvement and preservation of water quality, though costly, provided economic and social benefits that outweighed the expense. Now, however, some observers are beginning to question whether the costs of the 1972 Water Pollution Control Act may actually exceed those benefits. This book provides answers to some of the questions that have been raised. The authors give measures of several important nonmarket benefits of improved water quality in Colorado's South Platte River Basin and empirically test and confirm the Weisbrod and Krutilla proposals that the general public may be willing to pay for preservation of environmental amenities and that option value and other preservation values must be added to recreation-use values to give an accurate picture of the social benefits of environmental preservation and restoration. Their findings include the fact that even those who do not expect to use the river basin for recreation are willing to pay for the maintenance of a natural ecosystem and to bequest clean water to future generations. The authors also arrive at average amounts households are willing to pay for improved water quality to enhance enjoyment of water-based recreation activities. They suggest that, without such information, it is highly unlikely that sufficient resources will be allocated for the preservation of unique environments and for the improvement of those being degraded.
