Valuation Of Non Market Forest Goods Methodological And Empirical Studies

Nutrient recycling, habitat for plants and animals, flood control, and water supply are among the many beneficial services provided by aquatic ecosystems. In making decisions about human activities, such as draining a wetland for a housing development, it is essential to consider both the value of the development and the value of the ecosystem services that could be lost. Despite a growing recognition of the importance of ecosystem services, their value is often overlooked in environmental decision-making. This report identifies methods for assigning economic value to ecosystem servicesâ€"even intangible onesâ€"and calls for greater collaboration between ecologists and economists in such efforts.

Diploma Thesis from the year 2010 in the subject Economy - Environment economics, grade: 1,5, University of Bayreuth (Helmholtz Center for Environmental Research), language: English, abstract: This thesis investigates the potential and limitation of benefit transfer application for the economic valuation of non-marketed forest benefits in Saxony. This time- and cost saving valuation technique can support political and business decisions by transferring monetary costs and benefits from environmental changes from a studied to an unstudied site. As benefit transfer is currently not applied in Saxony, the question becomes how far it can contribute to a better-informed regional decision procedure. To elicit the methodological experiences of this application field, a literature review investigates the technical state of the art. From a methodological perspective, research and application manages spatial, temporal, and ecological site differences and accuracy tests very heterogeneously. The majority refines function transfer with varying models methodologically, drawing on primary valuation studies on forest recreation. A minor fraction concentrates on applications with simplistic unit transfer are of a likewise technically inconsistent manner. Absence of homogeneous ethodological performance and experiences suggest an application of unit transfer for Saxony following a guideline by Navrud (2010). In a compact manner it guides a benefit transfer application on forest benefits. A transfer of a WTP for forest biodiversity demonstrates income-adjusted unit transfer to be principally possible for contexts requiring knowledge gains. However, under current conditions it faces distinct limitations. Valuation is restricted to a small empirical pool on non-marketed forest benefits in such a way that most indirect use and non-use values remain unapproachable. Therefore, further primary valuation studies are fruitful additions to enlarge the number of appraisable benefits. If thorough benefit transfers are pursued in Saxony, incomeadjusted unit transfer is recommended according to Navrud’s (2010) guideline to enable a methodological homogeneous and well-reported valuation. Further, the literature should be collected from databases with empirical studies satisfying the criteria of site similarity. Facilitating a regular prospective application in Saxony, interest and demand needs to be raised to create a legal framework for the internalization of non-marketed forest benefits in political and business decisions.

This is a practical book with clear descriptions of the most commonly used nonmarket methods. The first chapters of the book provide the context and theoretical foundation of nonmarket valuation along with a discussion of data collection procedures. The middle chapters describe the major stated- and revealed-preference valuation methods. For each method, the steps involved in implementation are laid out and carefully explained with supporting references from the published literature. The final chapters of the book examine the relevance of experimentation to economic valuation, the transfer of existing nonmarket values to new settings, and assessments of the reliability and validity of nonmarket values. The book is relevant to individuals in many professions at all career levels. Professionals in government agencies, attorneys involved with natural resource damage assessments, graduate students, and others will appreciate the thorough descriptions of how to design, implement, and analyze a nonmarket valuation study.

A Primer on Nonmarket Valuation is unique in its clear descriptions of the most commonly used nonmarket valuation techniques and their implementation. Individuals working for government agencies, attorneys involved with natural resource damage assessments, graduate students, and others will appreciate the non-technical and practical tone of this book. The first section of the book provides the context and theoretical foundation of nonmarket valuation, along with practical data issues. The middle two sections of the Primer describe the major stated and revealed nonmarket valuation techniques. For each technique, the steps involved in implementation are laid out and described. Both practitioners of nonmarket valuation and those who are new to the field will come away from these methods chapters with a thorough understanding of how to design, implement, and analyze a nonmarket valuation study. The concluding section takes stock of the usefulness of nonmarket valuation, highlighting chapters on benefit transfer, the role of nonmarket valuation in real decisions about natural resources, and where nonmarket valuation is headed in the future. As a companion to A Primer on Nonmarket Valuation, a website has been developed, http://www.fs.fed.us/nonmarketprimerdata/. This website includes downloadable datasets for each of the techniques described in the Primer, as well as links to published journal articles and reports based on the data. The website also provides an opportunity for students to estimate models using the data.

Studienarbeit aus dem Jahr 2013 im Fachbereich VWL - Umweltökonomie, , Veranstaltung: Environmental Economics, Sprache: Deutsch, Abstract: Monetary valuation of environmental goods has by now become the subject of numerous economic books and articles. Interest in the topic seems to be increasing in the economics profession, and theoretical insight, methodological improvements and the numbers of empirical findings are expanding rapidly. The aim of such valuation is usually to incorporate environmental concerns into a cost-benefit analysis. Another purpose is to construct environmentally adjusted national income measures Environmental value estimates have also been combined with macroeconomic models, e.g. to estimate welfare effects of a climate treaty Further, estimated willingness to pay is now accepted in the USA as a basis for legal compensation claims for damages to natural resources caused by spill of hazardous substances (Nyborg, 1996) Valuation can simply be defined “as an attempt to put monetary values or to environmental goods and services or natural resources”. It is a key exercise in economic analysis and its results provide important information about values of environmental goods and services. This information can be used to influence decisions about wise use and conservation of forests and other ecosystems. The basic aim of valuation is to determine people’s preferences by gauging how much they are willing to pay (WTP) for given benefits or certain environmental attributes e.g. keep a forest ecosystem intact. In other words, valuation also tries to gauge how much worse off they would consider themselves to be as a result of changes in the state of the environment such as degradation of a forest. Economic valuation never refers to a stock, but only the change in a stock. If one speaks of the economic value of biodiversity, then one always means the economic value of a change of biodiversity. It is not a question of determining the ‘true’ value of biodiversity or ecosystems but valuing changes and comparing them with their alternatives, e.g. with a golf course vs without a golf course. Thus it is non-sense to ask “how much are the African National Parks worth?” A plausible question in this case would be: ‘WWF has proposed a new policy to prevent the huge losses of wildlife species from African National Parks. What is the monetary value of the benefits of this policy (i.e., the economic damages avoided)? Economists thus stress that the valuation should focus on changes rather than levels of biodiversity or ecosystem. [...]

In recent years, issues related to forests have come to prominence on the international agenda. This reflects growing concern over the fate of forest ecosystems and possible loss of the benefits which they provide. In the process of moving towards sustainable management of forests, there is growing demand for practical methodologies for full valuation of forests which permit the contributions of forests to be presented more clearly and in a manner which decision-makers can readily appreciate. Appropriate techniques should be able to adequately capture forest values in terms of the environmental, social and production functions and to recognise the worth of both marketed and non-marketed goods and services. This publication reviews approaches which can overcome the limitations of conventional analysis and provides a reference framework to help clarify what approaches to forest valuation can or cannot work. The publication is not itself a manual on valuation techniques but by reviewing the various approaches, makes it possible to select appropriate methodologies for which it then refers readers to other publications which can provide ''how to do'' details.

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 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
