摘要
The concept of payments for ecosystem services is being developed as an important means of providing a more diverse flow of benefits to people living in and around habitats valuable for conservation.The Kyoto Protocol,under the United Nations Framework Convention on Climate Change,includes a Clean Development Mechanism to provide for payments for certain forms of carbon sequestration that may benefit animal species(at least as an incidental benefit).Other market-based approaches for paying for carbon sequestration services outside the Kyoto framework are being promoted in various parts of the world.Another common form of payment for ecosystem services is compensating upstream landowners for managing their land in ways that maintain downstream water quality;this can include habitat management that benefits wild animal species.While biodiversity itself is difficult to value,it can be linked to other markets,such as certification in the case of sustainably-produced forest products.This paper expands on some of the markets for ecosystem services that also benefit wildlife,identifies relevant sources of information,and highlights some of the initiatives linking such markets to poverty alleviation.Making markets work for ecosystem services requires an appropriate policy framework,government support,operational institutional support,and innovation at scales from the site level to the national level.Zoologists have much to contribute to all of these steps.
