Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.

Download or read book Allelopathy in Ecological Agriculture and Forestry written by S.S. Narwal and published by Springer Science & Business Media. This book was released on 2000-09-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidly growing human population has increased the dependence on fossil fuel-based agrochemicals, such as fertilizers and pesticides, to produce the required agricultural and forestry products. This has exerted great pressure on non-renewable fossil fuel resources, which cannot last indefinitely. Not only do agrochemicals pollute the environment, but pests also become resistant to pesticides. Thus, present agricultural practices exploit natural resources, and damage fauna and flora and agroecosystems. One safe alternative to overcome these problems is the use of allelopathy to sustain development in agriculture and forestry and maintain a clean environment for future generations. This book is the Proceedings of the III International Congress on Allelopathy in Ecological Agriculture and Forestry, held on August 18-21, 1998, at the University of Agricultural Sciences, Dharwad, Karnataka, India, and provides an updated status of current allelopathy research in various leading countries, with the overall aim of developing new technologies for ecological agriculture and forestry in the 21st century. To date, no book on ecological agriculture has discussed these aspects, hence it is the first time that such information is available. The chapter contributors are leading specialists in their fields, and all chapters have been peer-reviewed by international referees. This book will be indispensable for agricultural scientists (agronomists, entomologists, nematologists, plant pathologists, horticulturists, plant breeders, agroforesters, foresters, soil scientists), bioscientists (biochemists, organic chemists, plant ecologists, microbiologists and limnologists), environmentalists, graduate students and farmers, as well as for organizations engaged in sustainable agriculture and organic agriculture.
Download or read book Forests on the Edge written by and published by . This book was released on 2005 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The private working land base of America's forests is being converted to developed uses, with implications for the condition and management of affected private forests and the watersheds in which they occur. The Forests on the Edge project seeks to improve understanding of the processes and thresholds associated with increases in housing density in private forests and likely effects on the contributions of those forests to timber, wildlife, and water resources. This report, the first in a series, displays and describes housing density projections on private forests, by watershed, across the conterminous United States. An interdisciplinary team used geographic information system (GIS) techniques to identify fourth-level watersheds containing private forests that are projected to experience increased housing density by 2030. Results indicate that some 44.2 million acres (over 11 percent) of private forests--particularly in the East, where most private forests occur--are likely to see dramatic increases in housing development in the next three decades, with consequent impacts on ecological, economic, and social services. Although conversion of forest land to other uses over time is inevitable, local jurisdictions and states can target efforts to prevent or reduce conversion of the most valuable forest lands to keep private working forests resilient and productive.

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.
Download or read book Horticulture Plants for People and Places Volume 2 written by Geoffrey R. Dixon and published by Springer. This book was released on 2014-06-10 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Trilogy explains “What is Horticulture?”. Volume two of Horticulture: Plants for People and Places analyses in depth the scientific, managerial and ecological concepts which underpin Environmental Horticulture. Chapters describe: Horticulture and the Environment, Woody Ornamentals, Herbs and Pharmaceuticals, Urban Greening, Rural Trees, Urban Trees, Turfgrass Science, Interior and External Landscaping, Biodiversity, Climate Change and Organic Production. Each is written by leading international experts. Sustainable use of resources and careful conservation are critically essential for the continuation of life on this Planet. Achieving this is where horticulture, natural flora and fauna and the environment interact in achieving sustainable development. Horticulture is the fundamental partner of ecological and environmental science and provides an understanding of eco-system services. Live plant networks are essential for rural and urban life. They are integral parts of natural communities, the context of historic and modern architecture and a means for rejuvenating cities and uniting communities. Plants provide urban, peri-urban and rural employment, business and tourism opportunities, leisure, rest and relaxation. These facets of Environmental Horticulture are clearly described in this book.
