Book Description
Ecosystem research has emerged in recent decades as a vital, successful, and sometimes controversial approach to environmental science. This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes and limitations of ecosystems studies, the book explores avenues for future ecosystem-level research.

Book Description
Ground water serves as the main source of drinking water for 50% of the United States as a whole—and for 97% of rural populations, in particular. In addition to public concern with point sources of contamination, such as landfills and hazardous waste disposal sites, current attention has now come to focus on the overall quality of ground-water resources. Regional Ground-Water Quality offers the first detailed guidance for conducting ground-water quality investigations in a regional context. This exceptional volume combines hydrogeologic and geochemical principles, as well as statistical principles, within a unique conceptual framework that helps readers produce efficient, meaningful, and successful ground-water assessments. Regional Ground-Water Quality will be a valuable resource when first approaching a regional-scale study and when designing specific regional-scale studies. Throughout the book, topics emphasize the value of studying regional ground-water quality at multiple spatial and temporal scales. Up-to-date coverage of essential processes and methodologies includes: multi-scale design concepts for regional ground-water quality studies the fate and transport of organic and inorganic materials, including nitrates, pesticides, pathogens, acid precipitation, natural radionuclides, saltwater intrusion, and problems in karst aquifers basic concepts of organic and inorganic chemistry a review of environmental isotopes and geochemical modeling statistical concepts for ground-water quality surveys and geostatistical analysis the effects of surface-water/ground-water interactions on ground-water quality the relationship between ground-water quality and land use regional geochemistry principles Readers will be brought completely up to date with the latest research in ground-water assessments, such as novel methods for dating young ground water, including the use of CFCs, tritium/helium-3, and krypton-85. The book also examines the uses of organic compounds as time and source markers, ground-water vulnerability analyses, applications of subsurface microbiology at the regional scale, and design of well-water surveys. Invaluable case studies drawn from international projects graphically demonstrate concepts discussed in the book. These case studies describe successful regional ground-water assessment efforts conducted in various areas and include a look at the uses and limitations of existing ground-water quality data. A first-of-its-kind resource, Regional Ground-Water Quality will be essential reading for scientists and engineers in hydrology, water resources, agricultural sciences, and environmental sciences. It will also be of interest to engineers and R&D personnel in government, industry, and private consulting, as well as to professionals involved with the design and interpretation of studies.

Book Description
The Great Basin, a stark and beautiful desert filled with sagebrush deserts and mountain ranges, is the epicenter for public lands conflicts. Arising out of the multiple, often incompatible uses created throughout the twentieth century, these struggles reveal the tension inherent within the multiple use concept, a management philosophy that promises equitable access to the region’s resources and economic gain to those who live there. Multiple use was originally conceived as a way to legitimize the historical use of public lands for grazing without precluding future uses, such as outdoor recreation, weapons development, and wildlife management. It was applied to the Great Basin to bring the region, once seen as worthless, into the national economic fold. Land managers, ranchers, mining interests, wilderness and wildlife advocates, outdoor recreationists, and even the military adopted this ideology to accommodate, promote, and sanction a multitude of activities on public lands, particularly those overseen by the Bureau of Land Management. Some of these uses are locally driven and others are nationally mandated, but all have exacted a cost from the region’s human and natural environment. In The Size of the Risk, Leisl Carr Childers shows how different constituencies worked to fill the presumed “empty space” of the Great Basin with a variety of land-use regimes that overlapped, conflicted, and ultimately harmed the environment and the people who depended on the region for their livelihoods. She looks at the conflicts that arose from the intersection of an ever-increasing number of activities, such as nuclear testing and wild horse preservation, and how Great Basin residents have navigated these conflicts. Carr Childers’s study of multiple use in the Great Basin highlights the complex interplay between the state, society, and the environment, allowing us to better understand the ongoing reality of living in the American West.

Book Description
This book gives a comprehensive presentation of our present understanding of the Earth's Hydrological cycle and the problems, consequences and impacts that go with this topic. Water is a central component in the Earth's system. It is indispensable for life on Earth in its present form and influences virtually every aspect of our planet's life support system. On relatively short time scales, atmospheric water vapor interacts with the atmospheric circulation and is crucial in forming the Earth's climate zones. Water vapor is the most powerful of the greenhouse gases and serves to enhance the tropospheric temperature. The dominant part of available water on Earth resides in the oceans. Parts are locked up in the land ice on Greenland and Antarctica and a smaller part is estimated to exist as groundwater. If all the ice over the land and all the glaciers were to melt, the sea level would rise by some 80 m. In comparison, the total amount of water vapor in the atmosphere is small; it amounts to ~ 25 kg/m2, or the equivalent of 25 mm water for each column of air. Yet atmospheric water vapor is crucial for the Earth’s energy balance. The book gives an up to date presentation of the present knowledge.
