This pioneer work in a complex, interdisciplinary, and still-developing field explores the prospects for a more comprehensive approach to evaluating environmental programs. Experts in the fields of biology, chemistry, ecology, economics, management, planning, sociology, political science, and public administration provide coherent, integrated perspectives on the task of environmental program evaluation. The essays are organized thematically, covering institutional, scientific, economic, and administrative topics. The volume will be a valuable text for practitioners, regulators, policymakers, and scholars in the fields of program evaluation, environmental policy, and environmental science.
