Valuation Of Biodiversity Benefits Selected Studies

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.

While biodiversity loss is an ecological phenomenon, it also has further dimensions – political, social and, last but not least, economic. From the economic perspective, the rapid loss of biological diversity can be viewed in two ways. First, the consequence of this deterioration process is a loss of options and an increase in scarcity of the environmental ‘good’, biodiversity. Second, economic activity and the structure of global and local economic institutions have frequently been identified as the major drivers of biodiversity loss. In economic terms, this constitutes a market failure – market-based economic activities lead to processes which undermine the long-term stability of these very activities. 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 and offers a novel, unifying perspective on the economic value of biodiversity. This framework demonstrates that biodiversity’s economic value mainly results from uncertainty about the future, regarding both supply of and demand for ecosystem services, and interconnections between ecosystems. The book goes on to identify suitable methods for economic valuation of biodiversity and discusses the currently underdeveloped and underused approach of deliberative monetary valuation. Combining a strong theoretical framework with practical examples, this book will be of great interest to students and researchers of ecological economics, ecosystem services, environmental values and environmental and resource economics.

"The international community has committed itself to achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the global, regional, and national levels. Yet, despite growing awareness, and major efforts in all countries, the latest evidence indicates that biodiversity continues to be lost at a terrifying pace, resulting in what some call the greatest mass extinction since dinosaurs roamed the planet, 65 million years ago. A range of methods have been developed to value ecosystems, and the services they provide, as well as the costs of conservation. The methods available are increasingly sensitive, and robust, but they are often incorrectly used. One reason is poor understanding of the purposes of valuation and what questions it can, or cannot, answer. As a result, decision makers may get misleading guidance on the value of ecosystems, and their conservation. In this context, the Bank, IUCN-The World Conservation Union, and the Nature Conservancy have worked together to clarify the aims and uses of economic valuation, focusing on the types of questions that valuation can answer, and the type of valuation that is best suited to each purpose. How Much is an Ecosystem Worth? is the result of that cooperation. It aims to provide guidance on how economic valuation can be used to address specific, policy-relevant questions about nature conservation."

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.

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.

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.
