Book Prehistoric Quarries and Lithic Production

Download or read book Prehistoric Quarries and Lithic Production written by Jonathon E. Ericson and published by Cambridge University Press. This book was released on 1984-07-26 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was originally published in 1984. For over a million years rocks provided human beings with the essential raw materials for the production of tools. Nevertheless we still know very little about the behaviour and processes that resulted in the creation of archaeological sites at or near lithic quarries. In the past archaeologists have placed much emphasis on the process of 'exchange' in their analysis of prehistoric economies while largely ignoring the sources of the exchanged objects. However, with the development of interest in the means of production, these sites have begun to take on a new significance. Prehistoric Quarries and Lithic Production is the first systematic study of archaeological sites that served as quarries for stone tools. Its theoretical and methodological importance will extend its appeal beyond those archaeologists concerned with lithic technology and prehistoric exchange systems to archaeologists and anthropologists in general and to geographers and geologists.

Book Cultural Resources Survey of the Eagles Nest Burn Malheur National Wildlife Refuge Harney County Oregon

Download or read book Cultural Resources Survey of the Eagles Nest Burn Malheur National Wildlife Refuge Harney County Oregon written by Kathryn Anne Toepel and published by . This book was released on 1983 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a cultural resources survey on 775 acres in the Malheur National Wildlife Refuge which are within the recent Eagles Nest Burn and are being considered for a reseeding project. An intensive survey of the area resulted in the recording of fourteen archaeological sites, several light scatters, and a number of isolated finds. All of the sites contain chert material which appears to occur naturally in the immediate area, suggesting that these sites were probably quarry workshops or chipping stations. Only three of the sites contained grinding tools indicative of plant gathering and processing activities. Projectile points suggest that the earliest use of the area may have occurred as early as 7,000 or more years ago, with the most intense occupation of the area occurring within the last 4,000 years. All of the sites in the project area warrant testing to determine whether they are eligible for inclusion in the National Register of Historic Places.

Book Irrigation Fundamentals

Download or read book Irrigation Fundamentals written by George H. Hargreaves and published by Water Resources Publication. This book was released on 1998 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: IRRIGATION FUNDAMENTALS is a comprehensive text on the basic principles and practices of applied agricultural irrigation. Written over a period of more than 10 years, it is based on the authors'' extensive experience in farming, consulting, research, teaching, and other related agricultural activities. The book is for use by teachers of introductory courses in irrigation, farmers who have some basic technical knowledge, and for administrators who need a general understanding of irrigation as an aid for policy decisions in water resource development and planning. Various factors that influence crop yield and production including climate, fertility, water, drainage, and agronomic practices are addressed. The various irrigation methods such as border, basin, contour, furrow, sub, sprinkle, and drip or trickle are described; and conditions are given for selection of the appropriate method to use. Recent developments and new technology are included herein when they have obvious practical applications, but for the most part the material presented in this book is based on well established principles and practices. Much of the content is very practical and much is essentially nontechnical. Nevertheless, some of the material covered in this book goes beyond the basic concepts in an attempt to better describe the relationships and techniques employed by irrigation scientists and irrigation engineers.From the Preface: The future of the world depends very much on how we manage natural resources. Since the year 1900 there has been a ninefold increase in global carbon emissions from burning fossil fuels, and the world population has increased about 3.7 times in this century. Vast areas of forests have been destroyed, and irrigated lands now produce 40% of the food supply. Due to depletion of groundwater reserves and an increase in population, irrigated area per capita is declining. Consequently, the irrigation of additional alluvial lands is a strategic necessity for all of humankind. Much of the alluvial lands cannot be made productive without prior development of water resources through flood control, drainage, and irrigation. The production of electricity through hydropower and the production of alcohol fuel from irrigated crops, as has been practiced for many years in Brazil, can slow the increase in carbon emissions. Such diverse developments are typically not separable; rather, they must be considered as integral parts of a comprehensive development plan. The conservation of natural resources and increasing productivity of irrigated lands are also strategic necessities. Much of the current technology is highly transferable and crop yields can be significantly increased on lands already under irrigation.The authors have worked in many countries in connection with resource inventories, teaching, and the planning, development and use of irrigation as a tool for increasing production and providing employment. They have written extensively and have been honored for their achievements. They have considerable experience with everything from primitive low-technology irrigation developments to highly developed irrigation in the USA and in dozens of countries around the world. Both of the authors have dedicated their careers to teaching, research, and consulting in agricultural irrigation and water resources development and planning. It is their hope and expectation that this book will provide incentives for investigating and documenting land and water resources, improving development, increasing crop yields, conserving resources, and improving the environment.

Book Determining the Economic Value of Water

Download or read book Determining the Economic Value of Water written by Robert A. Young and published by Routledge. This book was released on 2014-07-23 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water provides benefits as a commodity for agriculture, industry, and households, and as a public good such as fisheries habitat, water quality and recreational use. To aid in cost-benefit analysis under conditions where market determined price signals are usually unavailable, economists have developed a range of alternative valuation methods for measuring economic benefits. This volume provides the most comprehensive exposition to-date of the application of economic valuation methods to proposed water resources investments and policies. It provides a conceptual framework for valuation of both commodity and public good uses of water, addressing non-market valuation techniques appropriate to measuring public benefits - including water quality improvement, recreation, and fish habitat enhancement. The book describes the various measurement methods, illustrates how they are applied in practice, and discusses their strengths, limitations, and appropriate roles. In this second edition, all chapters have been thoroughly updated, and in particular the coverage of water markets and valuation of ecosystem services from water has been expanded. Robert Young, author of the 2005 edition, has been joined for this new edition by John Loomis, who brings additional expertise on ecosystem services and the environmental economics of water for recreational and other public good uses of water.
