This book addresses the technical, health, regulatory, and social aspects of ground water withdrawals, water use, and water quality in the metropolitan area of Mexico City, and makes recommendations to improve the balance of water supply, water demand, and water conservation. The study came about through a nongovernmental partnership between the U.S. National Academy of Sciences' National Research Council and the Mexican Academies of Science and Engineering. The book will contain a Spanish-language translation of the complete English text.

Introduction -- Mesozoic depositional evolution -- Cenozoic depositional evolution -- Petroleum habitat.

"The book examines some of these questions in a historic perspective, arguing that the depletion of natural resources in the Basin of Mexico is not just a recent phenomenon."--BOOK JACKET.

The Oxford Handbook of the Aztecs, the first of its kind, provides a current overview of recent research on the Aztec empire, the best documented prehispanic society in the Americas. Chapters span from the establishment of Aztec city-states to the encounter with the Spanish empire and the Colonial period that shaped the modern world. Articles in the Handbook take up new research trends and methodologies and current debates. The Handbook articles are divided into seven parts. Part I, Archaeology of the Aztecs, introduces the Aztecs, as well as Aztec studies today, including the recent practice of archaeology, ethnohistory, museum studies, and conservation. The articles in Part II, Historical Change, provide a long-term view of the Aztecs starting with important predecessors, the development of Aztec city-states and imperialism, and ending with a discussion of the encounter of the Aztec and Spanish empires. Articles also discuss Aztec notions of history, writing, and time. Part III, Landscapes and Places, describes the Aztec world in terms of its geography, ecology, and demography at varying scales from households to cities. Part IV, Economic and Social Relations in the Aztec Empire, discusses the ethnic complexity of the Aztec world and social and economic relations that have been a major focus of archaeology. Articles in Part V, Aztec Provinces, Friends, and Foes, focuses on the Aztec's dynamic relations with distant provinces, and empires and groups that resisted conquest, and even allied with the Spanish to overthrow the Aztec king. This is followed by Part VI, Ritual, Belief, and Religion, which examines the different beliefs and rituals that formed Aztec religion and their worldview, as well as the material culture of religious practice. The final section of the volume, Aztecs after the Conquest, carries the Aztecs through the post-conquest period, an increasingly important area of archaeological work, and considers the place of the Aztecs in the modern world.

Science Be Dammed is an alarming reminder of the high stakes in the management—and perils in the mismanagement—of water in the western United States. It seems deceptively simple: even when clear evidence was available that the Colorado River could not sustain ambitious dreaming and planning by decision-makers throughout the twentieth century, river planners and political operatives irresponsibly made the least sustainable and most dangerous long-term decisions. Arguing that the science of the early twentieth century can shed new light on the mistakes at the heart of the over-allocation of the Colorado River, authors Eric Kuhn and John Fleck delve into rarely reported early studies, showing that scientists warned as early as the 1920s that there was not enough water for the farms and cities boosters wanted to build. Contrary to a common myth that the authors of the Colorado River Compact did the best they could with limited information, Kuhn and Fleck show that development boosters selectively chose the information needed to support their dreams, ignoring inconvenient science that suggested a more cautious approach. Today water managers are struggling to come to terms with the mistakes of the past. Focused on both science and policy, Kuhn and Fleck unravel the tangled web that has constructed the current crisis. With key decisions being made now, including negotiations for rules governing how the Colorado River water will be used after 2026, Science Be Dammed offers a clear-eyed path forward by looking back. Understanding how mistakes were made is crucial to understanding our contemporary problems. Science Be Dammed offers important lessons in the age of climate change about the necessity of seeking out the best science to support the decisions we make.

Since the need to protect ground water from pollution was recognized, researchers have made progress in understanding the vulnerability of ground water to contamination. Yet, there are substantial uncertainties in the vulnerability assessment methods now available. With a wealth of detailed information and practical advice, this volume will help decision-makers derive the most benefit from available assessment techniques. It offers: Three laws of ground water vulnerability. Six case studies of vulnerability assessment. Guidance for selecting vulnerability assessments and using the results. Reviews of the strengths and limitations of assessment methods. Information on available data bases, primarily at the federal level. This book will be indispensable to policymakers and resource managers, environmental professionals, researchers, faculty, and students involved in ground water issues, as well as investigators developing new assessment methods.

This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

This reference is devoted to the pre-Columbian archaeology of the Mesoamerican culture area, one of the six cradles of early civilization. It features in-depth articles on the major cultural areas of ancient Mexico and Central America; coverage of important sites, including the world-renowned discoveries as well as many lesser-known locations; articles on day-to-day life of ancient peoples in these regions; and several bandw regional and site maps and photographs. Entries are arranged alphabetically and cover introductory archaeological facts (flora, fauna, human growth and development, nonorganic resources), chronologies of various periods (Paleoindian, Archaic, Formative, Classic and Postclassic, and Colonial), cultural features, Maya, regional summaries, research methods and resources, ethnohistorical methods and sources, and scholars and research history. Edited by archaeologists Evans and Webster, both of whom are associated with Pennsylvania State University. c. Book News Inc.
