North east India is a global biodiversity hotspot but a quite understudied area. Forest loss has always been problematic in the area. Using Landsat satellite data from three periods (70s, 80s/90s and 2010s), forest loss is assessed in sample protected areas and other sites in the study area, processing is undertaken using image processing and standard GIS tools. The landscape metrics of selected sites are assessed using the widely used program FRAGSTATS. Drivers of forest loss are central in the discussion of the study.
The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics
“Anyone who doubts the power of history to inform the present should read this closely argued and sweeping survey. This is rich, timely, and sobering historical fare written in a measured, non-sensationalist style by a master of his craft. One only hopes (almost certainly vainly) that today’s policymakers take its lessons to heart.”—Brian Fagan, Los Angeles Times Published in 2002, Deforesting the Earth was a landmark study of the history and geography of deforestation. Now available as an abridgment, this edition retains the breadth of the original while rendering its arguments accessible to a general readership. Deforestation—the thinning, changing, and wholesale clearing of forests for fuel, shelter, and agriculture—is among the most important ways humans have transformed the environment. Surveying ten thousand years to trace human-induced deforestation’s effect on economies, societies, and landscapes around the world, Deforesting the Earth is the preeminent history of this process and its consequences. Beginning with the return of the forests after the ice age to Europe, North America, and the tropics, Michael Williams traces the impact of human-set fires for gathering and hunting, land clearing for agriculture, and other activities from the Paleolithic age through the classical world and the medieval period. He then focuses on forest clearing both within Europe and by European imperialists and industrialists abroad, from the 1500s to the early 1900s, in such places as the New World, India, and Latin America, and considers indigenous clearing in India, China, and Japan. Finally, he covers the current alarming escalation of deforestation, with our ever-increasing human population placing a potentially unsupportable burden on the world’s forests.
Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.
The part played by the Brazilian tropical timber industry in deforesting the Amazon region has not been studied very much. This book describes the expansion of the timber industry in the Brazilian federal state of Para since the 1960s, when Amazon development became an important item on the government's agenda.
The 7-volume Encyclopedia of Biodiversity, Second Edition maintains the reputation of the highly regarded original, presenting the most current information available in this globally crucial area of research and study. It brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes of the work include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity. The science of biodiversity has become the science of our future. It is an interdisciplinary field spanning areas of both physical and life sciences. Our awareness of the loss of biodiversity has brought a long overdue appreciation of the magnitude of this loss and a determination to develop the tools to protect our future. Second edition includes over 100 new articles and 226 updated articles covering this multidisciplinary field— from evolution to habits to economics, in 7 volumes The editors of this edition are all well respected, instantly recognizable academics operating at the top of their respective fields in biodiversity research; readers can be assured that they are reading material that has been meticulously checked and reviewed by experts Approximately 1,800 figures and 350 tables complement the text, and more than 3,000 glossary entries explain key terms
"This book is a remarkably personal report of the authors’ trans-tropical experiences with forest dwellers. The experience was extensive, sometimes spanning years, and the report is the work of professional reporters, experienced at reaching to the core of critical issues of life and survival. The story is not a pretty one, and the prognosis is not good. But in their eyes the key lies in restoring and defending the rights of forest dwellers and encouraging in every way their age-old interest in preserving the integrity of forest lands. The authors are familiar with the international agencies and their programs, their successes and failures. Roger Stone was intimately involved in the World Commission on Forests and Sustainable Development and draws heavily on that experience. The book will strengthen the conclusions of that Commission to the effect that the world’s future lies heavily entangled with the continuity of forests globally, and that continuity hinges on respect for local interests."—George M. Woodwell, Director, Woods Hole Research Center "For twenty years, we have watched TV specials on the destruction of tropical forests -- an acre a second lost, every second for twenty years. This beautifully written book takes you right to the middle of the current international debate about what to do about it. It pulls no punches and proposes its own provocative solution. It offers a perspective that cannot be ignored and an answer that needs to be tried."—James Gustave Speth, Yale School of Forestry and Environmental Science "For more than a century, the conservation movement has dedicated its energy to protecting the Earth’s biodiversity. WWF has built its conservation philosophy and foundation for over forty years on principles of sound science, effective public policy, and recognition of the fundamental role local people bring to achieving tangible conservation results on the ground. Roger Stone and Claudia D’Andrea take us on a tour of the tropical forested regions of the world and capture important lessons about the merits of local control over forest resources. Their wide-ranging portrayal of community-based forest management arrangements, set within the global context of deforestation and loss of biodiversity, provides compelling testimony to the wisdom of empowering local people and nurturing their spirit as effective forest stewards."—Kathryn S. Fuller, President, World Wildlife Fund
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.
With gripping narrative power, The Condor's Shadow traces the ways in which human greed and ignorance have wreaked havoc on our ecological landscape. The heir apparent to Peter Matthiessen's 1959 classic Wildlife in America, The Condor's Shadow is a brilliant and compulsively readable study of the state of North American wildlife and what is being done to reverse the damage humans have caused. With equal respect for the smallest feather-mite and the fiercest grizzly, the frailest flower and the stateliest redwood, David S. Wilcove illustrates--in jargon-free, often witty prose--nature's delicate system of checks and balances, examining the factors that determine a species' vulnerability and the consequences of losing even the tiniest part of any ecosystem. An examination of both the heart-wrenching failures and stunning successes of our conservation efforts, The Condor's Shadow chronicles the destruction and resilience of our American wilderness and offers an insightful, eloquent overview that will appeal to avid conservationists and recreational nature-lovers alike.
