Natural capital - both nonrenewable resources and the renewable resources that make up ecosystems - is potentially endangered by the human process of adapting and modifying the world around us. The results of a workshop held following the second biannual conference of the International Society for Ecological Economics, Investing in Natural Capital emphasizes the essential connections between natural ecosystems and human socioeconomic systems, and the importance of ensuring that both remain resilient. Specific chapters deal with methodology, case studies, and policy questions and offer a thorough exploration of this provocative and important transdisciplinary alternative to conventional solutions to environmental problems.
