How Much is an Ecosystem Worth? pdf epub mobi txt 電子書 下載 2024
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. This title, prepared by the World Bank, IUCN-The World Conservation Union, and the Nature Conservancy, aims to provide guidance on how economic valuation can be used to address specific, policy-relevant questions about nature conservation. It clarifies 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.
