Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue reports research spanning from the analysis of indirect data, modeling, and laboratory and geological data confirming the intrinsic multidisciplinarity of gas hydrate studies. The study areas are (1) Arctic, (2) Brazil, (3) Chile, and (4) the Mediterranean region. The results furnished an important tessera of the knowledge about the relationship of a gas hydrate system with other complex natural phenomena such as climate change, slope stability and earthquakes, and human activities.
Download or read book Tropical Stream Ecology written by David Dudgeon and published by Elsevier. This book was released on 2011-05-04 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Stream Ecology describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in almost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Stream Ecology places an important emphasis on viewing research carried out in contributions from international literature. - First synthetic account of the ecology of all types of tropical streams - Covers all of the major tropical regions - Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems - Threats faced by tropical stream ecosystems and possible conservation actions - Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)
Download or read book Geothermal Resources written by R. Bowen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Arab oil embargo of 1974, it has been clear that the days of almost limitless quantities of low-cost energy have passed. In addition, ever worsening pollution due to fossil fuel consumption, for instance oil and chemical spills, strip mining, sulphur emission and accumulation of solid wastes, has, among other things, led to an increase of as much as 10% in the carbon dioxide content of the atmosphere in this century. This has induced a warming trend through the 'greenhouse effect' which prevents infrared radiation from leaving it. Many people think the average planetary temperatures may rise by 4°C or so by 2050. This is probably true since Antarctic ice cores evidence indicates that, over the last 160000 years, ice ages coincided with reduced levels of carbon dioxide and warmer interglacial episodes with increased levels of the gas in the atmosphere. Consequently, such an elevation of temperature over such a relatively short span of time would have catastrophic results in terms of rising sea level and associated flooding of vast tracts of low-lying lands. Reducing the burning of fossil fuels makes sense on both economic and environmental grounds. One of the most attractive alternatives is geothermal resources, especially in developing countries, for instance in El Salvador where geothermal energy provides about a fifth of total installed electrical power already. In fact, by the middle 1980s, at least 121 geothermal power plants were operating worldwide, most being of the dry steam type.

Download or read book Enduring Seeds written by Gary Paul Nabhan and published by University of Arizona Press. This book was released on 2002-10 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: As biological diversity continues to shrink at an alarming rate, the loss of plant species poses a threat seemingly less visible than the loss of animals but in many ways more critical. In this book, one of America's leading ethnobotanists warns about our loss of natural vegetation and plant diversity while providing insights into traditional Native agricultural practices in the Americas. Gary Paul Nabhan here reveals the rich diversity of plants found in tropical forests and their contribution to modern crops, then tells how this diversity is being lost to agriculture and lumbering. He then relates "local parables" of Native American agriculture—from wild rice in the Great Lakes region to wild gourds in Florida—that convey the urgency of this situation and demonstrate the need for saving the seeds of endangered plants. Nabhan stresses the need for maintaining a wide gene pool, not only for the survival of these species but also for the preservation of genetic strains that can help scientists breed more resilient varieties of other plants. Enduring Seeds is a book that no one concerned with our environment can afford to ignore. It clearly shows us that, as agribusiness increasingly limits the food on our table, a richer harvest can be had by preserving ancient ways. This edition features a new foreword by Miguel Altieri, one of today's leading spokesmen for sustainable agriculture and the preservation of indigenous farming methods.

Download or read book Biodiversity in Agriculture written by Paul Gepts and published by Cambridge University Press. This book was released on 2012-02-23 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of plant and animal agriculture represents one of the most important milestones in human evolution. It contributed to the development of cities, alphabets, new technologies, and ultimately to civilizations, but it has also presented a threat to both human health and the environment. Bringing together research from a range of fields including anthropology, archaeology, ecology, economics, entomology, ethnobiology, genetics and geography, this book addresses key questions relating to agriculture. Why did agriculture develop and where did it originate? What are the patterns of domestication for plants and animals? How did agroecosystems originate and spread from their locations of origin? Exploring the cultural aspects of the development of agricultural ecosystems, the book also highlights how these topics can be applied to our understanding of contemporary agriculture, its long-term sustainability, the co-existence of agriculture and the environment, and the development of new crops and varieties.
