This book represents a collection of papers on the subject of the creation of desert-like conditions as a result of human or natural causes. It provides considerable reference material for those interested in pursuing the various subtopics in greater depth.

This volume is an outgrowth of a project undertaken by the Environmental and Societal Impacts Group (ESIG) for the U.S. Environmental Protection Agency's Office of Policy Analysis to identify societal responses to extreme climate-related events in North America.

The United Nations Water Conference (in Argentina in March 1977) and the United Nations Conference to Combat Desertification (in Kenya in August 1977) reflect the worldwide attention that recent global food shortages and growing populations have drawn to the destruction of arable and potentially arable land. This collection of articles focuses on a primary form of such destruction: desertification-the creation of desert-like conditions in arid or semiarid regions either by changes in climate patterns or by human mismanagement, or both. The contributors-representing a range of disciplines-examine and evaluate the social, political, economic, environmental, and technical problems related to the causes and effects of desertification.

The past two decades have seen a remarkable broadening of interest in global warming from a research concern on the part of a limited number of scientists to a political problem on a worldwide scale. The nature of this transformation would itself be a fruitful study for a mixed team of social scientists and natural scientists. It would be valuable to assess the differing nature of the staging posts along this road: the First World Climate Conference in 1979, which was a meeting of scientists talking to scientists; the Villach Assessment of 1985, which was a meeting of scientists whose report was given attention by the policy advisers of a number of governments; the Second World Climate Conference of 1990, which consisted of a scientific meeting followed by a Ministerial Meeting; and the United Nations Framework Convention on Climate Change of 1992 signed by 158 countries at the UN Conference on Environment and Development in June 1992. The present publication is a welcome contribution of the followup to UNCED. By focusing on a specific problem, it avoids the pitfall of undue generalization and provides the basis for fruitful discussion between natural scientists, social scientists, and policymakers. To choose as the area of concentration a particular scale also helped to produce meaningful discussion likely to lead to action.

Teleconnections is a central concept in the scientific search for an improved understanding of potential linkages between weather and climate anomalies that occur over relatively large distances. The editors of this volume have brought together contributions from experts in the field, which together provide a comprehensive review of this important subject. This book will be of importance to all professional scientists and researchers in climatology and meteorology, particularly those concerned with air-sea interactions and their environmental impacts and the physical basis for and societal responses to forecasting. Graduate students in environmental science, meteorology and climate-related impact assessments will also find the book useful.

As we approach the end of the twentieth century, public and scientific attention is focusing increasingly on the detection and assessment of changes in our environment. This unique volume addresses the potential implications of global warming for fisheries and the societies which depend on them. Using a 'forecasting by analogy' approach, which draws upon experiences from the recent past in coping with regional fluctuations in the abundance or availability of living marine resources, it is shown how we might be able to assess our ability to respond to the consequences of future environmental changes induced by a potential global warming. The book takes the form of a series of integrated case studies from around the globe, which are presented by an interdisciplinary group of leading researchers. This important and thought-provoking volume will be of interest to a wide range of scientists working in the fields of biology, marine and environmental science, climatology, economics and anthropology, as well as resource managers and policy makers concerned with the health and future of living marine resources.

We are now in the "Age of Environmental Enlightenment" and global warming is seen as a major threat to the well-being of the world's communities. Today many researchers speculate that with global warming of the atmosphere there will be an increase in drought-related crop failures in areas already subject to drought. They contend that dry areas will get drier and wet areas wetter. Yet observations show that people are moving into regions that are relatively less fruitful with respect to agriculture productivity than the lands from which they emigrated. This book challenges the view that future droughts will be caused by climate change as opposed to human activities and demographic change. The author predicts future problems in these fragile environments, whether or not global climate changes occur. This book will intrigue researchers in environmental biology, environmental sciences, popular science, and agriculture, as well as policy makers and students.

This timely volume presents a synthesis of the ideas that emerged from a multidisciplinary colloquium held at the National Center for Atmospheric Research in August 1985. The aim was to assess the impact of drought as a major factor in the agrarian crisis in sub-Saharan Africa. Leading authorities engage in discussion of the African environment, the socio-political factors that generate famine, case studies of the effects of famine on these social structures, and finally possible lessons to be learnt on dealing with famine worldwide, thus developing an up-to-date and cohesive study of the problems of African development. Despite the current popular interest in the African famine problem, Drought and Hunger in Africa is the first major collection of the results that have emerged from the recent profusion of research relating to the subject. As such, this book has relevance, not only in Africa, but also to scientists, social-scientists and policy makers in the West, and to other areas of the third world which are facing the problems of drought and famine.

Headlines around the world about severe droughts, hurricanes, and floods caused by El Niño and La Niña appear every few years. El Niño is the second most important climate process after the changing seasons; its effects are widely known, but the equally serious impact of La Niña is only now beginning to be appreciated. Fully revised, Currents of Change clearly explains what El Niño and La Niña are and how they can be forecast. Examining for the first time the major El Niño of 1997-1998, Michael Glantz explains what we can learn from past events, how we can better manage climate-sensitive activities, and how to anticipate what future storms and droughts may occur. A century ago, it was of interest only to Peruvian fishermen and farmers. Today, scientists armed with tremendous computer models and satellites realize that El Niño and La Niña affect climatic conditions in seemingly remote parts of the world and are better able to predict which regions will be affected. Including the latest information about El Niño and La Niña, this new edition of Currents of Change will be useful to scientists, policymakers, economists, and interested readers alike. Michael Glantz is a Senior Scientist with the US National Center for Atmospheric Research (NCAR) in the Environmental and Societal Impacts Group, a program of NCAR. He is the coordinator of a 16-country El Niño impacts and response strategies study for the United Nations. Glantz is a member of numerous national and international committees and advisory bodies and is a recipient of the 1987 World Hunger Media Award, of UNEP's Global 500 Award, and the 1991 Mitchell Prize for Sustainable Development. He is the author of Climate Variability, Climate Change, and Fisheries (Cambridge, 1992) and Drought Follows the Plow (Cambridge, 1994). He lives in Boulder, Colorado.
