This study synthesizes data from 62 sites worldwide and finds that benefits from conservation and restoration often outweigh private ones, and these benefits rise with the social cost of carbon.
Nature provides many benefits for people, yet there are few data on how changes at individual sites impact the net value of ecosystem service provision. A 2002 review found only five analyses comparing the net economic benefits of conserving nature versus pursuing an alternative, more intensive human use. Here we revisit this crucial comparison, synthesizing recent data from 62 sites worldwide. In 24 cases with economic estimates of services, conservation or restoration benefits (for example, greenhouse gas regulation, flood protection) tend to outweigh those private benefits (for example, profits from agriculture or logging) driving change to the alternative state. Net benefits rise rapidly with increasing social cost of carbon. Qualitative data from all 62 sites suggest that monetization of additional services would further increase the difference. Although conservation and restoration did not universally provide greater net value than the alternative state, across a large, geographically and contextually diverse sample, our findings indicate that at current levels of habitat conversion, conserving and restoring sites typically benefits human prosperity. Nature benefits people in diverse ways, but insight on the relative value of conserving or restoring versus using intensively is limited. Synthesizing data from 62 sites worldwide, this study finds benefits from conservation and restoration often outweighing private ones and that these rise with the social cost of carbon.
