The Millennium Ecosystem Assessment(MEA), The Economics of Ecosystems & Biodiversity study(TEEB) and the Intergovernmental Platform on Biodiversityand Ecosystem Services (IPBES) provide a comprehensive anduseful framework to understand human dependence on ecosystemservices and how best to protect these services inperpetuity. In these three authoritative studies, paymentfor ecosystem services (PES) is listed as one of themechanisms that should allow societies to pay for themaintenance of these services. Ecosystem services arereceiving increased attention in the context of humandevelopment through The Economics of Ecosystems andBiodiversity study (TEEB). This is an internationalinitiative designed to call attention to the global economicbenefits of biodiversity, and the growing costs ofbiodiversity loss and ecosystem degradation. In TEEB sReport for Policymakers, PES schemes are listed aspotentially useful mechanisms to compensate those whomaintain the flow of ecosystem services. The studyemphasizes that PES schemes offer considerable potential toraise new funds for biodiversity or to use existing fundingmore efficiently, and that both the public and privatesectors can play a role in establishing PES in different contexts.
