The transfer of environmental values in time and space has increased rapidly with the widespread use of cost benefit analysis in project evaluation and regulatory assessments over the last three decades. The purpose of this volume is to take a snapshot of the research that is ongoing in the area of value transfer (benefit transfer). It includes papers by some of the most influential authors in the area, and covers the latest developments in the field. It will be useful for academics conducting research in this area and for practitioners in government agencies and ministries, as well as consulting firms.
