Washington Post: The world has vastly underestimated the economic value of nature in developing nations, according to a recent report, The Economics of Ecosystems and Biodiversity: Mainstreaming the Economics of Nature, released by the United Nations. Fresh water, coral reefs, and forests can be a source of livelihood for the rural and forest-dwelling poor, according to the study. The authors, led by banker Pavan Sukhdev, explain how habitats contribute to countries’ economic bottom lines. The report can also help conservation groups translate ecosystem benefits and concerns over species loss and habitat degradation into economic terms for policymakers.
