The definitive introduction to the field of ecological economics, this completely revised and updated second edition integrates the study and management of ecological and economic needs, sustaining both 'nature’s household' and 'humankind’s household.' It provides a unified understanding of natural and human-dominated ecosystems and reintegrates market economics within the limits posed by the biophysical world. Written by five of the leading figures in the field, this new edition adds a series of 'boxes' to expand and update information in the current text and addresses such forefront topics as the historical development of economics and ecology and motivation for incorporating humans into ecosystems.
