Between priceless and worthless: challenges in using market mechanisms for conserving biodiversity

This article appears in Transnational Environmental Law published by Cambridge University Press. Copyright 2012 Cambridge University Press There is growing interest in the use of market mechanisms, such as offsetting and payments for ecosystem services, to further the conservation of biodiversity. The specific needs of biodiversity mean that this approach faces significant challenges in terms of defining the units that can be the subject of the economic or market devices, of ensuring that such mechanisms do deliver conservation gains and of establishing appropriate governance arrangements. There are also ethical concerns that a market approach entails a commodification of nature which sacrifices some of the very elements which make nature valuable to us. The market-based schemes currently being operated and devised should be studied carefully to see how successfully these challenges can be met.
