Download or read book Traditional Arid Lands Agriculture written by Scott E. Ingram and published by University of Arizona Press. This book was released on 2015-04-02 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditional Arid Lands Agriculture is the first of its kind. Each chapter considers four questions: what we don’t know about specific aspects of traditional agriculture, why we need to know more, how we can know more, and what research questions can be pursued to know more. What is known is presented to provide context for what is unknown. Traditional agriculture, nonindustrial plant cultivation for human use, is practiced worldwide by millions of smallholder farmers in arid lands. Advancing an understanding of traditional agriculture can improve its practice and contribute to understanding the past. Traditional agriculture has been practiced in the U.S. Southwest and northwest Mexico for at least four thousand years and intensely studied for at least one hundred years. What is not known or well-understood about traditional arid lands agriculture in this region has broad application for research, policy, and agricultural practices in arid lands worldwide. The authors represent the disciplines of archaeology, anthropology, agronomy, art, botany, geomorphology, paleoclimatology, and pedology. This multidisciplinary book will engage students, practitioners, scholars, and any interested in understanding and advancing traditional agriculture.
Download or read book Murray Springs written by Caleb Vance Haynes and published by University of Arizona Press. This book was released on 2007-04-17 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Murray Springs Site in the upper San Pedro River Valley of southeast Arizona is one of the most significant Clovis sites ever found. It contained a multiple bison kill, a mammoth kill, and possibly a horse kill in a deeply stratified sedimentary context. Scattered across the buried occupation surface with the bones of late Pleistocene animals were several thousand stone tools and waste flakes from their manufacture and repair. Because of the unique occurrence of an algal black mat that buried the Clovis-age surface immediately after abandonment, the distributional integrity of the artifacts and debitage clusters is exceptional for Paleoindian sites. Excavation of the Clovis huntersÕ camp 50 to 150 meters south of the kills revealed artifactual evidence typical of hunting camp activity, including hide working and weapons repair. Impact flakes conjoining with Clovis points clearly tied the camp to the bison kill. The unique nature of the site and this comprehensive study of the excavated material constitute one of the most important contributions to our knowledge of Paleoindian hunters in the New World.
Download or read book Sedimentology and Sedimentary Basins written by Mike R. Leeder and published by John Wiley & Sons. This book was released on 2009-04-01 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sedimentology is a core discipline of earth and environmental sciences. It enquires the origins, transport and deposition of mineral sediment on the Earth's surface. The subject is a link between positive effects arising from the building of relief by tectonics and the negative action of denudation in drainage catchments and tectonic subsidence in sedimentary basins. The author addresses the principles of the subject, emphasising the advantages of a general science approach and the importance of understanding modern processes. Sedimentology and Sedimentary Basins is not an encyclopaedia, but attempts to stimulate interdisciplinary thought across the whole subject area and related disciplines. The book has been designed to meet the needs of earth and environmental science undergraduates.
Download or read book Sedimentary Processes Environments and Basins written by Gary Nichols and published by John Wiley & Sons. This book was released on 2009-03-05 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: For several decades Peter Friend has been one of the leading figures in sedimentary geology and throughout that time he has helped scores of other people by supervising doctoral students, collaborating with colleagues, especially in developing countries, and selflessly sharing ideas with fellow geologists. This collection of papers is a survey of the research frontier in basin dynamics, a field Peter Friend helped initiate, and a token of thanks from people who have benefited from an association with Peter during their careers. The papers in this book fall into four themes - Tectonics and sedimentation, Landscape evolution and provenance, Depositional systems and Fluvial sedimentation - which reflect Peter's research interests and are all important areas of current research in sedimentary geology. There are both case studies and review articles on these themes which reflect recent work, but the collection can also be considered to be a 'sampler' of sedimentary geology for anyone with broad interests in the Earth sciences.

Download or read book Ecology and Conservation of the San Pedro River written by Juliet C. Stromberg and published by University of Arizona Press. This book was released on 2009 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: contributors - biologists, ecologists, geomorphologists, historians, hydrologists, lawyers, and political scientists - weave together threads from their diverse perspectives to reveal the processes that shape the past, present, and future of the San Pedro's riparian and aquatic ecosystems. They review the biological communities of the San Pedro and the stream hydrology and geomorphology that affects its riparian biota. They then look at conservation and management challenges along three sections of the San Pedro, from its headwaters in Mexico in its confluence with the Gila River, describing legal and policy issues and their interface with science; activities related to mitigation, conservation, and restoration; and a prognosis of the potential for sustaining the basin's riparian system." "Complemented by a foreword written by James Shuttleworth, these chapters demonstrate the complexity of the San Pedro's ecological and hydrological conditions, showing that there are no easy --

Available in PDF, EPUB and Kindle. Book excerpt: The demand for water resulting from massive population and economic growth in the southwestern U.S. overwhelmed traditional uses of riparian areas. As a consequence, many of these uniquely-structured ecosystems have been altered or destroyed. Within recent years people have become increasingly aware of the many uses and benefits of riparian zones a
