Ecosystem services valuation has therefore recently assumed prominence in research and policy circles. In this illuminating volume, leading experts from around the world discuss the key methodological issues and challenges in valuing ecosystem services. Covering a cross-section of ecosystems and services in different sites, countries and regions, the collection also usefully presents case studies that value ecosystem services and experiences with operationalising valuation into policy.
