The desire to understand people’s influence on ecosystems has inspired scientific studies and analyses of the stress individuals and communities place on the environment, human well-being, and the tradeoffs between them. As an emerging discipline, Structural Human Ecology is devoted to unlocking the dynamic links between population, environment, social organization, and technology. The new field offers cutting-edge research in risk analysis that can be used to evaluate environmental policies and thus help citizens and societies worldwide learn how to most effectively mitigate human impacts on the biosphere. The essays in this volume were presented by leading international scholars at a 2011 symposium honoring the late Dr. Eugene Rosa, then Boeing Distinguished Professor of Environmental Sociology at WSU.
