Biodiversity may refer to the diversity of genes, species or ecosystems in general. These varying concepts of biodiversity occasionally lead to conflicts among researchers and policy makers, as each of them require a customized type of protection strategy. This book addresses the questions surrounding the merits of conserving an existing situation, evolutionary development or the intentional substitution of one genome, species or ecosystem for another. Any practical steps towards the protection of biodiversity demand a definition of that which is to be protected and, in turn, the motivations for protecting biodiversity. Is biodiversity a necessary model which is also useful, or does it carry intrinsic value? Debates like this are particularly complex when interested parties address it from different conceptual and moral perspectives. Comprised of three parts, each complemented by a short introductory paragraph, this collection presents a variety of approaches to this challenge. The chapters cover the perspectives of environmental scientists with expertise in evolutionary, environmental biology, systematic zoology and botany, as well as those of researchers with expertise in philosophy, ethics, politics, law and economics. This combination facilitates a truly interdisciplinary debate by highlighting hitherto unacknowledged implications that inform current academic and political debates on biodiversity and its protection. The book should be of interest to students and researchers of environment studies, biodiversity, environmental philosophy, ethics and management.

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 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.

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.

This book examines the role of ethics and philosophy in biodiversity conservation. The objective of this book is two-fold: on the one hand it offers a detailed and systematic account of central normative concepts often used, but rarely explicated nor justified, within conservation biology. Such concepts include ‘values’ (both intrinsic, instrumental, and, more recently, relational), ‘rights’, and ‘duties’. The second objective is to emphasize to environmental philosophers and applied ethicists the many interesting decision-making challenges of biodiversity conservation. The book argues that a nuanced account of instrumental values provides a powerful tool for reasoning about the values of biodiversity. It also scrutinizes relational values, the concept of rights of nature, and risk, and show how moral philosophy proves indispensable for these concepts. Consequently, it engages with recent suggestions on normative aspects of biodiversity conservation, and show the need for moral philosophy in biodiversity conservation. The overriding aim of this book is to provide conservation biologists and policy-makers with a systematic overview of concepts and assessments of the reasons for reaching prescriptive conclusions about biodiversity conservation. This will prove instrumental in clarifying the role of applied ethics and a refined understanding of the tools it can provide. This title will be of interest to students and scholars of conservation biology, conservation policy, environmental ethics and environmental philosophy.

CONSERVATION BIOGEOGRAPHY The Earth’s ecosystems are in the midst of an unprecedented period of change as a result of human action. Many habitats have been completely destroyed or divided into tiny fragments, others have been transformed through the introduction of new species, or the extinction of native plants and animals, while anthropogenic climate change now threatens to completely redraw the geographic map of life on this planet. The urgent need to understand and prescribe solutions to this complicated and interlinked set of pressing conservation issues has lead to the transformation of the venerable academic discipline of biogeography – the study of the geographic distribution of animals and plants. The newly emerged sub-discipline of conservation biogeography uses the conceptual tools and methods of biogeography to address real world conservation problems and to provide predictions about the fate of key species and ecosystems over the next century. This book provides the first comprehensive review of the field in a series of closely interlinked chapters addressing the central issues within this exciting and important subject.

The loss of the earth's biological diversity is widely recognized as a critical environmental problem. That loss is most severe in developing countries, where the conditions of human existence are most difficult. Conserving Biodiversity presents an agenda for research that can provide information to formulate policy and design conservation programs in the Third World. The book includes discussions of research needs in the biological sciences as well as economics and anthropology, areas of critical importance to conservation and sustainable development. Although specifically directed toward development agencies, non-governmental organizations, and decisionmakers in developing nations, this volume should be of interest to all who are involved in the conservation of biological diversity.
