Humans Forests And Global Environmental Change

The inclusion of forests as potential biological sinks in the Kyoto Protocol to the United Nations Framework Convention on Climate Change (UNFCCC) in 1997 has attracted international attention and again has put scientific and political focus on the world's forests, regarding their state and development. The international discus sion induced by the Kyoto Protocol has clearly shown that not only the tropical rain forests are endangered by man's activities, but also that the forest ecosystems of boreal, temperate, mediterranean and subtropical regions have been drastically modified. Deforestation on a large scale, burning, over-exploitation, and the degra dation of the biological diversity are well-known symptoms in forests all over the world. This negative development happens in spite of the already existing knowledge of the benefits of forests on global energy and water regimes, the biogeochemical cycling of carbon and other elements as well as on the biological and cultural diversity. The reasons why man does not take care of forests properly are manifold and complex and there is no easy solution how to change the existing negative trends. One reason that makes it so difficult to assess the impacts of human activity on the future development of forests is the large time scale in which forests react, ranging from decades to centuries.

Global environmental change often seems to be the most carefully examined issue of our time. Yet understanding the human sideâ€"human causes of and responses to environmental changeâ€"has not yet received sustained attention. Global Environmental Change offers a strategy for combining the efforts of natural and social scientists to better understand how our actions influence global change and how global change influences us. The volume is accessible to the nonscientist and provides a wide range of examples and case studies. It explores how the attitudes and actions of individuals, governments, and organizations intertwine to leave their mark on the health of the planet. The book focuses on establishing a framework for this new field of study, identifying problems that must be overcome if we are to deepen our understanding of the human dimensions of global change, presenting conclusions and recommendations.

Forests throughout the world are undergoing rapid, far-reaching change as a result of natural and anthropogenic disturbances. The challenge is to manage these forests in ways that avoid formulaic approaches to complex issues. This book takes on the challenge of balancing local economies, wood products, and biodiversity by proposing diverse new approaches to forest management using new research from the moist coniferous forests of the Pacific Northwest. --

This publication is extracted from a much larger report, Global Environmental Change: Research Pathways for the Next Decade, which addresses the full range of the scientific issues concerning global environmental change and offers guidance to the scientific effort on these issues in the United States. This volume consists of Chapter 7 of that report, "Human Dimensions of Global Environmental Change," which was written for the report by the Committee on the Human Dimensions of Global Change of the National Research Council (NRC). It provides findings and conclusions on the key scientific questions in human dimensions research, the lessons that have been learned over the past decade, and the research imperatives for global change research funded from the United States.

The human species faces many threats to its health - perhaps to its survival. Taking an interesting perspective, Planetary Overload forcefully points out the consequences to human health of ongoing degradation of Earth's ecosystems. In a broad-based, accessible analysis, A. J. McMichael examines ecological disruptions - land degradation, ozone depletion, temperature increases, and loss of genetic diversity through the extinction of species, among others - and compellingly demonstrates their potentially disastrous results, including food shortages, new and intensified disease patterns, rising seas, mass refugee problems, and cancers, blindness, and immune suppression from increased ultraviolet radiation. While other books on the subject analyse only the environmental impact of these problems, McMichael relates each of these insidious processes back to its ultimate impact on human health. He thoroughly considers these problems within a broad evolutionary, biological, social, and economic context, and also explores the underlying problems contributing to environmental breakdown, especially the relations between the world's rich and poor. This book will be of interest to environmentalists, public health professionals, policy makers, environmental studies and human ecology scholars, and anyone wishing a lucid, rational assessment of today's pressing ecological concerns.

'Seeing the Forest and the Trees' examines changes in land cover & land use in forested regions as major contributors to global environmental change.
