This book assesses the current available information concerning the major scientific problems related to environmental consequences of a possible nuclear war. The contributors address a broad range of topics, among them the effects of blast, heat, and local radioactive fallout; the likely dispersal patterns and residence times of radioactive debris in the troposphere and stratosphere; the probable long-term effects on both the local and global biosphere and radiological consequences for humans; the effect on the global environment of widespread fires in urban and industrialized regions; and the likely significant decrease of stratospheric ozone with a resulting long-term increase in harmful UV radiation received at the ground. The authors point to problem areas where current information is inadequate or completely lacking and discuss the role of the scientist in developing such information as a contribution to the elimination of the nuclear war threat.

This book is a collection of reports from international scholars on the environmental effects of various large scale river management programs. It examines the different aspects of river basin development with special focus on the type of problems likely to be encountered in developing countries.

In our critical attempts to solve the pressing current problems of a limited water supply, it is essential that we act always with a global view to the future. Recognizing this, an international group of scholars-from the Soviet Union, Canada, Africa, and the United States-met to review together their experiences and research on the environmental effects of a number of large scale river management programs. This edited collection of their reports provides a balanced view of a vital element in the total ecosystem. Their analysis points out the urgent need to take account of long-term trends in climate, to consider all feasible management alternatives, and, especially, to manage demand (as opposed to simply increasing water supply) and to defer irreversible action until all environmental impacts are estimated.

The High Plains region was once called the Great American Desert and thought to be, in the words of explorer Stephen Long, "wholly unfit for cultivation." Now we know that beneath the surface, unbeknownst to the explorers and early settlers, lies the Ogallala aquifer, an underground formation that stretches for 800 miles from the Texas panhandle to South Dakota. It holds more water than Lake Huron. Indeed, the Ogallala has been referred to as the sixth Great Lake. It is the water pumped for irrigation from the Ogallala that has enabled a naturally dry region to produce up to 40 percent of America's beef and 20 to 25 percent of its food and fiber, an output worth about $20 billion. In the forty years since the invention of center pivot irrigation, the High Plains aquifer system has been depleted at an astonishing rate. In 1978 the volume of water pumped from the aquifer exceeded the annual flow of the Colorado River. In Texas, water levels are down 200 feet in some areas. In Kansas, 700 miles of rivers that once flowed year round no longer flow at all. In short, the High Plains may be becoming the desert it was once thought to be. Is it too late to solve the problem? Geographers David Kromm and Stephen White assembled nine of the most knowledgeable scholars and water professionals in the Great Plains to help answer that question. The result is a collection of essays that insightfully examine the dilemmas of groundwater use. From a variety of perspectives they address both the technical problems and the politics of water management to provide a badly needed analysis of the implications of large-scale irrigation. They have included three case studies: the Nebraska Sand Hills, Northwestern Kansas, and West Texas. Kromm and White provide an introduction and conclusion to the volume.

To fully analyze the relationship between water management, environmental conditions and public policy, this book reviews the development of water management and evaluates it from the perspective of the quality of the natural environment. Examples are drawn from around the world, and range from local watershed management to international river basin planning, with emphasis placed on integrative approaches. Successful water management is crucial for the proper operation of natural environmental systems and for the support of human society.
