Human Data Can Improve Ecosystem Service Models, Study Says

Protected forests in Brazil, Costa Rica, Indonesia, and Thailand have prevented the release of more than 1 billion tons

of carbon dioxide into the atmosphere, an ecosystem service worth at least $5 billion, Georgia State University economists found. Their conclusion about the monetary benefit of those forest protections is based on a new method they derived for valuing services such as carbon capture, conservation, and improvements in air and water quality. Instead of relying on modeling alone, the new method uses interviews and on-the-ground data to see how conservation programs affect human behavior and impact ecosystems. By combining the two types of information — environmental models and social science data — public officials can gain more realistic insights into how a particular policy might affect the environment and the people who interact with it, the researchers write in the Proceedings of the National Academy of Sciences.
