Resource-management decisions, especially in the area of protecting and maintaining biodiversity, are usually incremental, limited in time by the ability to forecast conditions and human needs, and the result of tradeoffs between conservation and other management goals. The individual decisions may not have a major effect but can have a cumulative major effect. Perspectives on Biodiversity reviews current understanding of the value of biodiversity and the methods that are useful in assessing that value in particular circumstances. It recommends and details a list of components-including diversity of species, genetic variability within and among species, distribution of species across the ecosystem, the aesthetic satisfaction derived from diversity, and the duty to preserve and protect biodiversity. The book also recommends that more information about the role of biodiversity in sustaining natural resources be gathered and summarized in ways useful to managers. Acknowledging that decisions about biodiversity are necessarily qualitative and change over time because of the nonmarket nature of so many of the values, the committee recommends periodic reviews of management decisions.

This major reference work the first of its kind provides a comprehensive and authoritative introduction to the large and growing literature on contingent valuation. It includes entries on over 7,500 contingent valuation papers and studies from over 130 countries covering both the published and grey literatures. This book provides an interpretive historical account of the development of contingent valuation, the most commonly used approach to placing a value on goods not normally sold in the marketplace. The major fields catalogued here include culture, the environment, and health application. This bibliography is an ideal starting point for researchers wanting to find other studies that have valued goods or used techniques similar to those they are interested in. For those wanting to conduct meta analyses, the book will serve as an invaluable guide to source material. For those wanting to conduct meta analyses, the book will serve as an invaluable guide to source material. In addition to the print edition we offer access, for purchasers of the book, to a website providing the contents of as a searchable Word document and in a variety of standard bibliographic database forms. Contingent Valuation is an indispensable reference source for researchers, scholars and policymakers concerned with survey approaches to the problem of environmental valuation.

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.

Just as individuals have preferences regarding the various goods and services they purchase every day, so they also hold preferences regrding public goods such as hose provided by the naural environment. However, unlike provate goods, environmental goods often cannot be valued by direct reference o any market price. Thsi amkes economic analysis of the costs and benefits of environmental change problematic. Over the past few decades a number of methods have developed to address this problem by attempting to value environmental preferences. Principal among hese has been the contingent valuation (CV) method which uses surveys to ask individuals how much they would be willing to pay or willing to accept in compensation for gains and losses of environmental goods. The period from the mid-1980s to the present day has seen a m,assive expansion in use of the CV method. From its originalroots int eh USA, through Europe and the developed world, the method has now reached worldwide application with a substantial proportion of current studies being undertaken in developing countries where environmental services are often the dominating determinant of everyday living standards. The method has simultaneously moved from the realm of pure academic speculation into the sphere of instiutional decision analysis. However, the past decade also witness a developing critique of the CV method with a number of commentators questioning the underlying validity of its dervied valuations. This volume, therefore, reflects a time of heated debate, as wellas from commentators who see it as an interesting experimental tool regardless of the question of absolute validity of estimates. The book embraces the theoritical, methodologicl, empirical, and institutional aspects of the current debate. It covers US, European , and developing country applications, and the institutional frameworks within which CV studies are applied.
