Download or read book Pasture Landscapes and Nature Conservation written by Bernd Redecker and published by Springer Science & Business Media. This book was released on 2002-05-28 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems and aims of nature conservation in Europe is to protect semi-open landscapes. The development during the past decades is characterized by an ongoing intensivation of land use on the one hand, and an increasing number of former meadows and pastures lying fallow caused by changing economic conditions on the other hand. In several countries the estabishment of larger "pasture landscapes" with a mixed character of open grassland combined with shrubs and forests has been recognized as one solution to this problem. The book gives an overview of the European projects concerning to this topic - nature conservation policy and strategies, scientific results and practical experiences creating large scale grazing systems.

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.

Available in PDF, EPUB and Kindle. Book excerpt: "This book shows the real West, not the one seen in postcards or imagined from romantic movies and novels. With photographs and essays, it shows not only the most shocking cases of overgrazing, but also the subtle changes that signal ecological disruption on a massive scale. Welfare Ranching explains the cultural and historical causes of the wasting of the West and offers a vision of the renewal that is possible if citizens are willing to demand that their government shift land management priorities to serving the public and natural good, rather than facilitating private gain. Ultimately, this book points the way to the greatest opportunity yet remaining for ecological restoration and wildlife protection in this country."--BOOK JACKET.

Download or read book The Sportsman s Voice written by Mark Damian Duda and published by Venture Pub. This book was released on 2010 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Product Description: Nearly 34 million Americans ages 16 and older head outdoors to hunt and fish every year. Through hunting and fishing license fees and excise taxes on hunting and fishing equipment, hunters and anglers are responsible for the majority of fish and wildlife conservation funding in the United States. Fish and wildlife management programs funded by these fees have conserved millions of acres of habitat and have brought back many species, including wild turkey, wood duck, bald eagle, and pronghorn antelope, from unhealthy population levels. Understanding hunting and fishing, and hunters and anglers as a constituency, is vital to effectively managing the nation's natural resources. Policy makers, legislators, fish and wildlife professionals, conservation organizations, and hunters and anglers themselves have an unmet need for science-based, comprehensive information on hunting and fishing to inform their understanding, communications, decision making, and planning. The Sportsman's Voice: Hunting and Fishing in America, is the first book that provides a comprehensive, up-to-date look at hunting and fishing in America. It bridges the gap between hundreds of scientific studies of the human dimensions of conservation and on-the-ground situations, giving this information meaningful context and real-world utility.
