Harold A. Mooney and Richard J. Hobbs At present there is enormous concern about the changes that are occurring on the surface of the earth and in the earth's atmosphere, primarily as a result of human activities. These changes, particularly in the atmosphere, have the potential for altering the earth's habitability. International pro grams unprecedented in scope, including the International Geosphere Biosphere Program, have been initiated to describe and understand these changes. The global change program will call for coordinated measure ments on a global scale of those interactive physical and biological pro cesses that regulate the earth system. The program will rely heavily on the emerging technology of remote sensing from airborne vehicles, particularly satellites. Satellites offer the potential of continuously viewing large seg ments of the earth's surface, thus documenting the changes that are occur ring. The task, however, is not only to document global change, which will be an enormous job, but also to understand the significance of these changes to the biosphere. Effects on the biosphere may cover all spatial scales from global to local. The possibility of measuring biosphere function remot~ly and continuously from satellite imagery must be explored quickly and thoroughly in order to meet the challenge of understanding the con sequences of global change. Initial guidelines and approaches are currently being formulated (Dyer and Crossley, 1986; JOI, 1984; NAS, 1986; Rasool, 1987). There are many conceptual and technical issues that must be resolved H. A. Mooney and R. J.

In this newly revised and expanded edition of the award-winning International Environmental Policy, Lynton Keith Caldwell updates his comprehensive survey of the global international movement for protection of the environment. Serving as a history of international cooperation on environmental issues, this book focuses primarily on the development of international agreements and institutional arrangements--both governmental and nongovernmental--along with the impact of science, technology, trade, and communication on environmental policy. With implications for multinational commerce, population policy, agriculture, energy issues, biological and cultural diversity, transnational equity, ideology, and education, this book takes a broad view of the policy outcomes of what may be the most important social movement of the 20th century, and addresses the events and politics that have significantly affected the movement over the last twenty years and will continue to affect it into the next century.

Changing the Global Environment: Perspectives on Human Involvement focuses on the extent of global environmental changes and the extent to which technology can be employed to improve the global environment. This book is divided into three sections. Section I sets forth a broad perspective on specific conceptual issues of concern such as the sustainable use of the global ocean; deforestation and extinction of species; large-scale alteration of biological productivity due to transported pollutants; and soil degradation and conversion of tropical rainforests. The second section discusses technologies of remote sensing, computer-based data systems, and advanced chemical analytical techniques. The interactions among social, environmental, and economic goals and the role that technological advances might play in attaining these goals are deliberated in Section III. This publication is valuable to environmentalists and students interested in how technologies can change man's perception of the environment.

The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.

This book delivers stimulating input for a broad range of researchers, from geographers and ecologists to psychologists interested in spatial perception and physicists researching in complex systems. How can one decide whether one surface or spatial object is more complex than another? What does it require to measure the spatial complexity of small maps, and why does this matter for nature, science and technology? Drawing from algorithmics, geometry, topology, probability and informatics, and with examples from everyday life, the reader is invited to cross the borders into the bewildering realm of spatial complexity, as it emerges from the study of geographic maps, landscapes, surfaces, knots, 3D and 4D objects. The mathematical and cartographic experiments described in this book lead to hypotheses and enigmas with ramifications in aesthetics and epistemology.

This book is a unique collection of advanced research on natural, human-made, and coupled human–natural systems. The contributors analyze the current state of knowledge, address methodological challenges, and explore engaging cases. The chapters demonstrate the balanced disciplinary strength and discuss interdisciplinary perspectives. The authors undertake a holistic and spatially integrative analysis to understand the sustainability of environmental, economic, and social systems, emphasizing the coupled nature of such systems. In particular, the chapters explore biodiversity conservation and natural resources, the sustainability of natural and human-altered ecosystems, sustainability–vulnerability issues in coupled human–natural systems, mechanisms to foster sustainable environmental practices, eventually accumulating sustainability research and practice in various fields. More than that, the challenges of educational and economic systems are studied closely. The authors rely on unique data, develop regional and local knowledge, and explore global trends at local scales. A separate focus is devoted to human health and well-being. The book has seven sections: (1) Advances in Natural and Coupled Human–Natural Systems Research; (2) Economic Systems in the Age of Digital Changes and Unstable Environments; (3) Sustainable Social Systems, Migration Flows, and Social Cohesion; (4) Taking Action for Greater Security and Effective Partnerships for Sustainable Development; (5) Systemic Challenges and Changes in Education Systems in Russia and Around the Globe; (6) Advances in Cultural Traditions and Innovation, Development Barriers, and Social Stability; (7) Human Health and Well-being: Taking Action for Sustainable Development. Written by scholars and practitioners from multiple fields of knowledge, the book is designed for a broader audience interested in the following research areas: systems research and thinking, sustainability research and thinking, system dynamics, management of complexity, decision analysis, organization theory, governance, natural resources, environmental studies, economic development, social policies, cleaner production, innovation, cultural studies, and sustainable practices.
