Book Description
Winner of an Outstanding Academic Title Award from CHOICE Magazine Encyclopedia of Environmental Management gives a comprehensive overview of environmental problems, their sources, their assessment, and their solutions. Through in-depth entries and a topical table of contents, readers will quickly find answers to questions about specific pollution and management issues. Edited by the esteemed Sven Erik Jørgensen and an advisory board of renowned specialists, this four-volume set shares insights from more than 500 contributors—all experts in their fields. The encyclopedia provides basic knowledge for an integrated and ecologically sound management system. Nearly 400 alphabetical entries cover everything from air, soil, and water pollution to agriculture, energy, global pollution, toxic substances, and general pollution problems. Using a topical table of contents, readers can also search for entries according to the type of problem and the methodology. This allows readers to see the overall picture at a glance and find answers to the core questions: What is the pollution problem, and what are its sources? What is the "big picture," or what background knowledge do we need? How can we diagnose the problem, both qualitatively and quantitatively, using monitoring and ecological models, indicators, and services? How can we solve the problem with environmental technology, ecotechnology, cleaner technology, and environmental legislation? How do we address the problem as part of an integrated management strategy? This accessible encyclopedia examines the entire spectrum of tools available for environmental management. An indispensable resource, it guides environmental managers to find the best possible solutions to the myriad pollution problems they face. Also Available Online This Taylor & Francis encyclopedia is also available through online subscription, offering a variety of extra benefits for researchers, students, and librarians, including: Citation tracking and alerts Active reference linking Saved searches and marked lists HTML and PDF format options Contact us to inquire about subscription options and print/online combination packages.

Human Impact on Environment and Sustainable Development in Africa
Author: Michael B.K. Darkoh
Publisher: Routledge
ISBN: 1351756656
Category : Science
Languages : en
Pages : 456
Book Description
This title was first published in 2003. Based on a blend of knowledge and perspectives from a variety of disciplines this volume examines the human-environment interaction in Africa, with a focus on the economic, social and political processes that generate environmental change and problems in this region. Currently there are controversies over and challenges to such concepts and issues as environment-human relationships, ecological resilience, decertification, sustainable development, globalization and North-South dialogue. This book draws upon past and present research findings to discuss these issues. It features: an examination of the characteristics, processes and patterns of environmental crises; an analysis of the principal issues and challenges facing policy makers and implementers; and the promotion of awareness of theoretical, empirical and comparative research. The volume not only seeks to answer some of the old questions, but also open up new ones for further discussion.

Physics and Modelling of Wind Erosion
Author: Yaping Shao
Publisher: Springer Science & Business Media
ISBN: 9780792366577
Category : Science
Languages : en
Pages : 444
Book Description
This book provides a comprehensive summary of the recent developments in wind-erosion research and a clear outline of its future directions. The physics of wind-erosion, from particle entrainment to transport and deposition, is described with rigor from the viewpoints of fluid dynamics and soil physics. The techniques for quantitative wind-erosion prediction through computational modelling constitutes a unique feature of this book in contrast to others published in the same field. For the first time, wind-erosion has been considered systematically as a multidisciplinary subject. The author has advocated the development of integrated wind-erosion modelling systems which couple dynamic models for the atmosphere and land surface with spatially distributed data for land-surface conditions. The successful applications of such a system have demonstrated its usefulness in wind-erosion assessment and prediction on regional to continental scales. This book offers a valuable reference point for researchers and postgraduate students engaged in wind-erosion related studies, ranging from global climate change to atmospheric aerosols, dust storms, air quality, and land conservation.

Tropical and sub-tropical West Africa - Marine and continental changes during the Late Quaternary
Author: P. Giresse
Publisher: Elsevier
ISBN: 0080556035
Category : Science
Languages : en
Pages : 407
Book Description
West Africa and the eastern Atlantic stretching from Mauritania in the north to Namibia in the south offer a large latitudinal stretch incorporating nearly symmetrical climatic gradients from the Equator. On the time scale of Quaternary Glacial and Interglacial cycles, today, we possess well-documented and recently published marine sedimentary records showing changes in oceanic and atmospheric circulations and terrestrial fluxes. Deep-sea sediment records contain a wide range of palaeoenvironmental indicators like oxygen and carbon isotopes, alkenones, foraminiferal and other planktonic assemblages over time periods up to and greater than 125,000 years. These are signals of temperature and circulation shifts and allow Interglacial and Glacial comparisons on a regional and inter-hemispheric scale. However, this effort to synthesize the existing knowledge cannot yet aspire to a global modelling. Linking with terrestrial records, albeit spatially patchy and generally lacking a firm chronology, this book points to shorter time scale chronologies from lakes, marshes and river deposits. Diverse and not very wellknown literature, both French and English, is reported here. Lastly, the book records recent knowledge of the first steps of human occupation of frequently hostile environments and considers the environmental impact of ancient and modern societies.* Covers the recent studies about marine Quaternary environments off West Africa, as well as continental Quaternary environments of tropical and sub-tropical West Africa (over 10,000 to 100,000 years)* Compares the parallel between palae-oenvironmental trends according to latitudinal gradients

Soils, Ecosystem Processes, and Agricultural Development
Author: Shinya Funakawa
Publisher: Springer
ISBN: 4431564845
Category : Nature
Languages : en
Pages : 384
Book Description
The main objective of this book is to integrate environmental knowledge observed in local agriculture, based on the understanding of soils science and ecology, and to propose possible technical solutions and a more integrated approach to tropical agriculture. The chapters describe and analyze the ecological and technical countermeasures available for mitigating environmental degradation due to the increasing agricultural activities by humans, based on our scientific understanding of traditional agriculture in the tropics. This is an effective approach, as such ecological and technical tools previously involved in traditional activities are expected to be easily incorporated into present agricultural systems. The book starts with a rather classical pedological issue and analyzed traditional agricultural practices with different resource management strategies in terms of their modification of natural biological processes. It focuses on the present situation of tropical agriculture; that is, resource utilization in modern agriculture after application of technical innovation (increased application of chemical fertilizers as well as agricultural chemicals). Here, possible technical approaches to resource management that reasonably support agricultural production whilst mitigating environmental degradation are discussed. The negative impacts of agricultural development on our environment are rapidly growing, yet we are increasingly dependent on the agricultural sector for food and energy. The situation is similar in the tropics, where subsistence agriculture with low input management has long comprised most agricultural systems. Comparison of ecological and/or agronomical studies between different continents are still rare; therefore, this analysis may help clarify what is an essential problem when considering technical transportation beyond continents and/or between temperate and tropical regions.
