Ecological economics is a new transdisciplinary approach to understanding and managing the ecology and economics of our world for sustainability on local, regional, and global scales. The previous isolation of these two fields has led to economic and environmental policies that have been mutually destructive rather than reinforcing in the long term. This book brings together these two disciplines in chapters covering the basic worldview of ecological economics; accounting, modeling, and analysis of ecological economicl systems; and necessary institutional changes and case studies.
