Human Ecology: A Theoretical Essay, by Amos Hawley, presents for the first time a unified theory of human ecology by a scholar whose name is virtually synonymous with the discipline. Focused on the interaction between society and environment, human ecology is an attempt to deal holistically with the phenomenon of human organization. Beginning in the first quarter of the century, sociologists such as Park, Burgess, and McKenzie developed the study of human ecology to account for the dynamics of change in American cities. Over time, theorists have reached beyond the boundaries of sociology, drawing on the findings of economics, political science, anthropology, and bioecology, to understand the relationship of human beings to their environment. Hawley has successfully integrated the scattered theses of this wide-ranging discipline into a schematic whole. The early human ecologists seized on the analogy of plant communities as a way of understanding urban communities. Hawley here maintains that the most important contribution to human ecology of the lexicons of plant and animal ecologies is the perspective of collective life as an adaptive process consisting in an interaction of environment, population, and organization. From the adaptive profess, he argues, emerges the ecosystem, a concept that serves as a common denominator for bioecology and human ecology. Hawley has codified the theory of human ecology by a set of deductive hypotheses that establish its claims to coherence and comprehensiveness. His model charts a synthesis of ecological concepts ranging from adaptation and equilibrium through growth in temporal and spatial dimensions to convergence and openness. The essay underscores the critical importance of transportation and communication technology to the shaping of the human ecological system. Human Ecology brings concision and elegance to this holistic perspective and will serve as a point of reference and orientation for anyone interested in the powers and scope of the ecological approach.

First published in This volume grew out of concerns raised by the contributors and a few others over the current status of human ecology within the field of sociology. Stemming from conferences and subsequent discussions by a group of sociologist-demographers on recent developments in sociological human ecology which started at the annual meeting of the Population Association of America in 1976, the original essays contained in this book are designed to review and assess the current state of knowledge in the field.

The completion of this volume would not have been possible without the generous and dedicated help of numerous people. The book had its genesis in a conference held at Cornell University in the fall of 1990 that was organized by Dudley Poston, Paul Eberts, and Michael Hannan, all professors at the time at Cornell. With the very generous financial assistance of David Call, then the dean of Cornell's College of Agriculture and Life Sciences, Poston, Eberts, and Hannan put together a two-day conference oflectures and papers by human ecologists from Cornell University and elsewhere. The conference focused on sociological human ecology and celebrated the fortieth anniversary of the publication of Amos Hawley's Human Ecology (Ronald Press 1950). Professor Hawley was the keynote speaker at the conference. Many of the authors of the chapters in this volume presented earlier versions at the Cornell conference in 1990. Cornell's Departments of Rural Sociology and Sociology also contrib uted financial assistance; however, without Dean Call's very generous support, the conference would not have been possible. A few months after the conference, Poston and Michael Micklin discussed the possibility of asking the various authors of the Cornell conference papers to revise them for publication in a volume on sociological human ecology. Many opted to do so, but others did not because of time and other kinds of commitments and constraints.

Nearly all of the major perspectives, focal points and debates in environmental sociology are reflected in this collection of essays. The volume exceeds the bounds of conventional theory by surveying societies and their natural biophysical environments.

The third edition of John Hannigan’s classic undergraduate text has been fully updated and revised to highlight contemporary trends and controversies within global environmental sociology. Environmental Sociology offers a distinctive, balanced treatment of environmental issues, reconciling Hannigan’s much-cited model of the social construction of environmental problems and controversies with an environmental justice perspective that stresses inequality and toxic threats to local communities.
