Book Description
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.
Challenges for Rural America in the Twenty-First Century

Book Description
The twentieth century was one of profound transformation in rural America. Demographic shifts and economic restructuring have conspired to alter dramatically the lives of rural people and their communities. Challenges for Rural America in the Twenty-First Century defines these changes and interprets their implications for the future of rural America. The volume follows in the tradition of "decennial volumes" co-edited by presidents of the Rural Sociological Society and published in the Society's Rural Studies Series. Essays have been specially commissioned to examine key aspects of public policy relevant to rural America in the new century. Contributors include:Lionel Beaulieu, Alessandro Bonnano, David Brown, Ralph Brown, Frederick Buttel, Ted Bradshaw, Douglas Constance, Steve Daniels, Lynn England, William Falk, Cornelia Flora, Jan Flora, Glenn Fuguitt, Nina Glasgow, Leland Glenna, Angela Gonzales, Gary Green, Rosalind Harris, Tom Hirschl, Douglas Jackson-Smith, Leif Jensen, Ken Johnson, Richard Krannich, Daniel Lichter, Linda Lobao, Al Luloff, Tom Lyson, Kate MacTavish, David McGranahan, Diane McLaughlin, Philip McMichael, Lois Wright Morton, Domenico Parisi, Peggy Petrzelka, Kenneth Pigg, Rogelio Saenz, Sonya Salamon, Jeff Sharp, Curtis Stofferahn, Louis Swanson, Ann Tickameyer, Leanne Tigges, Cruz Torres, Mildred Warner, Ronald Wimberley, Dreamal Worthen, and Julie Zimmerman.

Book Description
Rangelands comprise between 40 and 50 percent of all U.S. land and serve the nation both as productive areas for wildlife, recreational use, and livestock grazing and as watersheds. The health and management of rangelands have been matters for scientific inquiry and public debate since the 1880s, when reports of widespread range degradation and livestock losses led to the first attempts to inventory and classify rangelands. Scientists are now questioning the utility of current methods of rangeland classification and inventory, as well as the data available to determine whether rangelands are being degraded. These experts, who are using the same methods and data, have come to different conclusions. This book examines the scientific basis of methods used by federal agencies to inventory, classify, and monitor rangelands; it assesses the success of these methods; and it recommends improvements. The book's findings and recommendations are of interest to the public; scientists; ranchers; and local, state, and federal policymakers.
