Available in PDF, EPUB and Kindle. Book excerpt: An engaging call to understand and protect groundwater, the primary source of drinking water for almost half of the world's population Groundwater is essential for drinking water and food security. It provides enormous environmental benefits by keeping streams and rivers flowing. But a growing global population, widespread use of industrial chemicals, and climate change threaten this vital resource. Groundwater depletion and contamination has spread from isolated areas to many countries throughout the world. In this accessible and timely book, hydrology expert William M. Alley and science writer Rosemarie Alley sound the call to protect groundwater. Drawing on examples from around the world, including case studies in the United States, Canada, Australia, India, and Sub-Saharan Africa, the authors examine groundwater from key scientific and socioeconomic perspectives. While addressing the serious nature of groundwater problems, the book includes stories of people who are making a difference in protecting this critical resource.

This book was released on 2007-01-01 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hinterlands and Regional Dynamics in the Ancient Southwest is the first volume dedicated to understanding the nature of and changes in regional social autonomy, political hegemony, and organizational complexity across the entire prehistoric American Southwest. With geographic coverage extending from the Great Plains to the Colorado River, and from Mesa Verde to the international border, the volumeÕs ten case studies synthesize research that enhances our understanding of the ancient SouthwestÕs highly variable demographic, land use, and economic histories. For this volume, ÒhinterlandsÓ are those areas whose archaeological records do not disclose the ceramic, architectural, and network evidence that initially led to the establishment of the Hohokam, Chaco, and Casas Grandes regional systems. Employing a variety of perspectives, such as the cultural landscapes approach, heterarchy, and the common-pool resource model, as well as technical methods, such as petrographic and stylistic-attribute analyses, the volumeÕs contributors explore variation in hinterland identities, subsistence ecology, and sociopolitical organization as regional systems expanded and contracted between the 9th and 14th centuries AD. The hinterlands of the prehistoric Southwest were home to a substantial number of people and were often used as resource catchments by the inhabitants of regional systems. Importantly, hinterlands also influenced developments of nearby regional systems, under whose footprint they managed to retain considerable autonomy. By considering the dynamics between hinterlands and regional systems, the volume reveals unappreciated aspects of the ancient SouthwestÕs peoples and their lives, thereby deepening our awareness of the regionÕs rich and complicated cultural past.
