The loss of biodiversity has put increasing pressure on the stability and continuity of ecosystems, and their ability to provide goods and services to mankind. This valuable new book addresses this issue and presents an integrated ecological-economic perspective on the analysis of biodiversity loss and conservation. It adopts a multidisciplinary approach and attempts both to provide a definition of biodiversity benefits as well as investigate alternative perspectives on biodiversity. The book also presents a classification of biodiversity values and effectively illustrates which economic valuation methods can best measure which type of biodiversity value. The distinguished authors move on to discuss the utility of the application of the economics-ecology interface and integrated modelling for the assessment of biodiversity values. In doing so, they consider the use of multi-criteria evaluation and meta-analytical methods to deal with the aggregation of information from multiple disciplines and past valuation studies, respectively. The book concludes by addressing the role of biodiversity indicators and monetary information for policy design and biodiversity management, devoting special attention to the certification and the ecolabeling of biodiversity benefits. The integration of economic and ecological theories and methods, and the strong methodological orientation will be of immense benefit to students, academics and researchers of environmental economics, environmental science and ecology. Policymakers involved with nature policy and management will also find this volume to be of great practical value.

The contingent valuation technique for measuring the economic value of environmental goods and services has become increasingly popular in recent years and has many advantages over other revealed or stated preference methods. It has been criticised, however, for being inconsistent with economic theory by reflecting altruistic motives and moral obligations. This book examines the role of the 'warmglow' effect (the pleasure derived from giving to good causes or being concerned about the environment) in contingent valuation studies and examines whether warmglow is an underlying force in CV responses. The author argues that if the empirical evidence suggests that warmglow is important, then its magnitude needs to be assessed in the valuation function. The ultimate goal is to disentangle the warmglow effect from the original 'willingness-to-pay' mean estimates and compute a dry estimate, free from any warmglow. The author conducts a CV application in a Portuguese natural park to test the validity of this approach. He tests the premise that the financial contribution by itself constitutes a source of well-being to the respondent and also discusses whether the warm glow component should or should not be included when formulating benefit-cost analysis and environmental policy. This innovative book will be essential reading to all students and scholars of the economics of environmental valuation.
