This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
Download or read book Rainfed Farming Systems written by Philip Tow and published by Springer Science & Business Media. This book was released on 2011-09-16 with total page 1324 pages. Available in PDF, EPUB and Kindle. Book excerpt: While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

Download or read book The Changing Scale of American Agriculture written by John Fraser Hart and published by University of Virginia Press. This book was released on 2003 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few Americans know much about contemporary farming, which has evolved dramatically over the past few decades. In The Changing Scale of American Agriculture, the award-winning geographer and landscape historian John Fraser Hart describes the transformation of farming from the mid-twentieth century, when small family farms were still viable, to the present, when a farm must sell at least $250,000 of farm products each year to provide an acceptable level of living for a family. The increased scale of agriculture has outmoded the Jeffersonian ideal of small, self-sufficient farms. In the past farmers kept a variety of livestock and grew several crops, but modern family farms have become highly specialized in producing a single type of livestock or one or two crops. As farms have become larger and more specialized, their number has declined. Hart contends that modern family farms need to become integrated into tightly orchestrated food-supply chains in order to thrive, and these complex new organizations of large-scale production require managerial skills of the highest order. According to Hart, this trend is not only inevitable, but it is beneficial, because it produces the food American consumers want to buy at prices they can afford. Although Hart provides the statistics and clear analysis such a study requires, his book focuses on interviews with farmers: those who have shifted from mixed crop-and-livestock farming to cash-grain farming in the Midwest agricultural heartland; beef, dairy, chicken, egg, turkey, and hog producers around the periphery of the heartland; and specialty crop producers on the East and West Coasts. These invaluable case studies bring the reader into direct personal contact with the entrepreneurs who are changing American agriculture. Hart believes that modern large-scale farmers have been criticized unfairly, and The Changing Scale of American Agriculture, the result of decades of research, is his attempt to tell their side of the story.

Download or read book Land Use Competition written by Jörg Niewöhner and published by Springer. This book was released on 2016-07-29 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contributes to broadening the interdisciplinary knowledge basis for the description, analysis and assessment of land use practices. It presents conceptual advances grounded in empirical case studies on four main themes: distal drivers, competing demands on different scales, changing food regimes and land-water competition. Competition over land ownership and use is one of the key contexts in which the effects of global change on social-ecological systems unfold. As such, understanding these rapidly changing dynamics is one of the most pressing challenges of global change research in the 21st century. This book contributes to a deeper understanding of the manifold interactions between land systems, the economics of resource production, distribution and use, as well as the logics of local livelihoods and cultural contexts. It addresses a broad readership in the geosciences, land and environmental sciences, offering them an essential reference guide to land use competition.

Book excerpt: What? Los Angeles was the original wine country of California, leading the state's wine production for more than a century? Los Angeles County was the agricultural center of North America until the 1950s? And where today's freeways soar, cows calmly chewed their cud? How could that be? Los Angeles, the capital of asphalt and Klieg lights, was once a paradise filled with grapevines and bovines, so abundant with Nature's gifts that no one could imagine a more pastoral place? Los Angeles County was the center of an agricultural empire. Today, it is the nation's most populous urban metropolis. What happened? Where did the green go? As Americans connect with gardens, farmers markets, and urban farms, most are unaware that each of these activities have deep roots in Los Angeles, and that the healthy food they savor literally had its roots in L.A. This book is for all who treasure the country's agrarian history.
Download or read book Global Livestock Production Systems written by Timothy P. Robinson and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.
