This book was released on 2010-07-25 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

Download or read book Wrightscapes written by Charles and Berdeana Aguar and published by McGraw Hill Professional. This book was released on 2002-06-22 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: THE FIRST IN-DEPTH LOOK AT THE ENVIRONMENTAL DESIGNS OF “AMERICA’S FAVORITE ARCHITECT” . . . FRANK LLOYD WRIGHT CONTAINS MANY NEVER BEFORE PUBLISHED PHOTOGRAPHS AND SITE PLANS “ . . . a comprehensive and intriguing look at the work of Frank Lloyd Wright from the outside. It provides a view from the perspective of his designs in settings or landscapes . . . the point of view is to see how the designs of the outside flow into, out of, around, and in a few classic cases, under the architecture of the building.” -- John Crowley, Dean, College of Environmental Design, University of Georgia Shedding light on a fascinating yet previously unexamined topic, Wrightscapes analyzes 85 of Frank Lloyd Wright’s designs paying particular attention to site planning, landscape design, community scale and regional planning. The authors include many original diagrams, rare archival material, and some 200 photographs and site plans, many never published before, detailing Wright’s residential and public work and his urban design initiatives. A true collectors item Wrightscapes is a pleasure to read and a joy to own. Frank Lloyd Wright is perhaps best remembered for his unmatched mastery of the organic style of architecture – where a structure’s form and material blend harmoniously with its natural surroundings. Less well known, but equally inspirational are the contributions Wright brought to landscape and site design. His creations in this area reflect a holistic, sustainable, and environmentally-sensitive utilization of plants, climate, solar power, and natural lighting. Wrightscapes is the first definitive book to address Frank Lloyd Wright’s landscapes and environments. The authors provide a unique new perspective of the man and his work by presenting previously ignored, yet important aspects of his achievements, interests, and career, including little-known facts such as: * Wright originated the visionary concept of a rear living-room opening into a garden terrace -- fifty years before the California architects generally credited with the concept * Wright actually designed the first carport – three decades prior to the date he is said to have “invented” it * During the first forty years of Wright’s career, he personally and professionally interacted with, and was significantly influenced by, designers who today would be described as landscape architects * Wright had a career-long fascination with community-scale planning Wrightscapes also chronicles how and why Wright’s famous ecological sensibilities were established, delving into Japanese and European influences as well as forces that shaped both the young and the mature architect. The authors also demonstrate how his design aspirations went far beyond the accepted definitions of architecture. In order to be as complete as possible, Wrightscapes even includes a detailed listing of “dos and don’ts” for owners of homes designed by Frank Lloyd Wright Here is truly groundbreaking, richly-illustrated coverage of an important yet unexplored aspect of Frank Lloyd Wright’s genius.

Book excerpt: Agriculture in this century is confronted with the challenges of ensuring global food security. Diminishing land and water resources, a rapid increase in population particularly in developing countries, and onset of climate change are the key limitations towards sustainability of the agriculture sector. The situation demands that we address the problems of agriculture using a system approach. This is a comprehensive book outlining the issues being faced by the agriculture sector worldwide. The book covers diversified topics including water scarcity, food security, international research collaboration, sustainable agriculture, soil erosion, weed management, micro nutrients, biotechnology, investment in research, sustainable viticulture and desertification. The key theme of the book is achieving food security at the national and global scale. Various dimensions of food security are addressed simultaneously while analyzing the effect of population, water scarcity, sustainable agriculture and desertification in detail. Case studies from Pakistan, Russia, the Philippines and Portugal are presented with national focus and their implications at the global level. Each chapter presents state-of-the-science synthesis on the subject matter and solutions to the specific problems. Chapters include contributions from vastly experienced scientists in their area of expertise. This book can be of particular interest for students, professors, researchers, farmers and policy makers who intend to have a food secure 21st century.

Available in PDF, EPUB and Kindle. Book excerpt: Named U.S. Poet Laureate for 2004-2006, Ted Kooser is one of America's masters of the short metaphorical poem. Dana Gioia has remarked that Kooser has written more perfect poems than any poet of his generation. In Flying at Night: Poems 1965-1985, Kooser has selected poems from two of his earlier works, Sure Signs and One World at a Time (1985). Taken together or read one at a time, these poems clearly show why William Cole, writing in the Saturday Review, called Ted Kooser "a wonderful poet," and why Peter Stitt, writing in the Georgia Review, proclaimed him "a skilled and cunning writer. . . . An authentic 'poet of the American people.'"

Download or read book Farm Profits and Adoption of Precision Agriculture written by U.s. Department of Agriculture and published by Createspace Independent Publishing Platform. This book was released on 2017-02-15 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precision agriculture (PA) and its suite of information technologies-such as soil and yield mapping using a global positioning system (GPS), GPS tractor guidance systems, and variable-rate input application-allow farm operators to fine-tune their production practices. Access to detailed, within-field information can decrease input costs and increase yields. USDA's Agricultural Resource Management Survey shows that these PA technologies were used on roughly 30 to 50 percent of U.S. corn and soybean acres in 2010-12. Previous studies suggest that use of PA is associated with higher profits under certain conditions, but aggregate estimates of these gains have not been available. In this report, a treatment-effects model is developed to estimate factors associated with PA technology adoption rates and the impacts of adoption on profits. Labor and machinery used in production and certain farm characteristics, like farm size, are associated with adoption as well as with two profit measures, net returns and operating profits. The impact of these PA technologies on profits for U.S. corn producers is positive, but small. Keywords: Crop production information technologies, precision agriculture, variablerate technology, soil tests, global positioning system maps, guidance systems.

This book was released on 2012-06-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indicators used in the past to measure human societies' success have proven to be insufficient. Economic production indicators such as gross domestic product (GDP) and the Human Development Index (HDI) fail to reflect the state of natural resources or ecological conditions and both focus exclusively on the short term, without indicating whether national policies are sustainable over longer periods of time. The Inclusive Wealth Report 2012 presents an index that measures the wealth of nations by carrying out a comprehensive analysis of a country's capital assets, including manufactured, human and natural capital, and its corresponding values: the Inclusive Wealth Index (IWI). Results show changes in inclusive wealth from 1990 to 2008 and feature a long-term comparison to GDP for an initial group of 20 countries. This report provides policy-makers and planning authorities with a tool to assess the state of a country's productive base and its development over time.
