These case studies cover the state of the art on economic valuation and on the interface between economic and ecological valuation.

This Handbook describes the types of values usually associated with biodiversity. While there are exceptions to the need to prioritise economic values over other values, economic valuation has a sound theoretical foundation that can help clarify the tradeoffs implicit in public policy decisions.

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.

Biodiversity loss is one of the major resource problems facing the world, and the policy options available are restricted by inappropriate economic tools which fail to capture the value of species and their variety. This study describes in non-technical terms how cost-benefit analysis techniques can be applied to species and species loss, and how they provide a measure of the efficiency of conservation measures. Only when conservation can be shown to pass such a basic economic test, the authors claim, will it be incorporated into policies.;David Pearce has also written Blueprint for a Green Economy.

Environmental Valuation in Developed Countries will be of interest to policy makers and economist in search of a variety of methodologies related to environmental valuation. Political Studies Review This is the second of two volumes of case studies that illustrate how environmental economists place values on environmental assets and on the flows of goods and services generated by those assets. The first volume, Valuing the Environment in Developing Countries, illustrates methodologies and applications of valuation techniques in the developing world; this volume concentrates on developed or wealthy nations where the first examples of economic valuation of the environment were carried out. This important book assembles studies that discuss broad areas of application of economic valuation from amenity and pollution through to water and health risks, from forestry to green urban space. In this, his last book, the late David Pearce brought together leading European experts, contributors to some two dozen case studies exploring the frontiers of economic valuation of natural resources and environmental amenity in the developed world. Essays on the role of valuation in environmental policy, environmental justice and green accounts are presented, and case study topics include: valuing forestry benefits GM crops water use and quality externalities in the electricity sector renewable energy benefits electricity transmission line disamenity urban greenspace chemical risks noise pollution. Economic valuation has undoubtedly made an important contribution to the environmental debate, and the contributors illustrate how sophisticated techniques have become, and how powerful their application can be. As such, this significant volume will prove essential reading for academics, researchers, students and practitioners in the field of environmental economics.

This thought provoking book draws together prominent international authorities to discuss the key methodological issues and challenges in valuing ecosystem services. Covering a cross-section of ecosystems and services in different sites, countries and

This book provides an ecological economic perspective on the value of diversity in ecosystems. Combining insights from various sub-disciplines of ecology and environmental/ecological economics the author constructs a conceptual framework which identifies the ways in which biodiversity influences human well-being are identified and offers a novel, unifying perspective on the economic value of biodiversity.
