Available in PDF, EPUB and Kindle. Book excerpt: The study of soils has taken on increased importance because a rapidly expanding population is placing demands on the soil never before experi enced. This has led to an increase in land degradation. Land degradation is one of the most severe problems facing mankind. Volume 11 of Advances in Soil Science was devoted entirely to this critical area of soil science. The editors of that volume, R. Lal and B.A. Stewart, defined soil degradation as the decline in soil quality caused by its misuse by humans. They further stated that soil degradation is a major concern for at least two reasons. First, it undermines the productive capacity of an ecosystem. Second, it affects global climate through alterations in water and energy balances and disruptions in cycles of carbon, nitrogen, sulfur, and other elements. Through its impact on agricultural productivity and environment, soil deg radation leads to political and social instability, enhanced rate of deforesta tion, intensive use of marginal and fragile lands, accelerated runoff and soil erosion, pollution of natural waters, and emission of greenhouse gases into the atmosphere. In fact, soil degradation affects the very fabric of mankind.

Download or read book Soil Processes and the Carbon Cycle written by Rattan Lal and published by CRC Press. This book was released on 2018-02-06 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.

This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Energy Agency Bioenergy Agreement was initiated as the Forestry Energy Agreement in 1978. It was expanded in 1986 to form the Bioenergy Agreement. Since that time the Agreement has thrived with some fifteen countries (Austria, Belgium, Canada, Denmark, Finland, Italy, Japan, Netherlands, New Zealand, Norway, Sweden, Switzerland, United Kingdom, United States and the CEC) currently being signatories. The objective of the Agreement is to establish increased programme and project cooperation between the participants in the field of bioenergy. The environmental consequences of intensive forest harvesting have been the subject of intense interest for the Agreement from its initiation. This interest was formulated as a Cooperative Project under the Forestry Energy Agreement in 1984. It developed further under each of the subsequent three-year Tasks of the Bioenergy Agreement (Task III, Activity 3 "Nutritional consequences of intensive forest harvesting on site productivity", Task VI, Activity 6 "Environmental impacts of harvesting" and more recently Task IX, Activity 4 "Environmental impacts of intensive harvesting". The work has been supported by five main countries from within the Bioenergy Agreement: Canada, New Zealand, Sweden, UK, and USA. The continued work has resulted in a significant network of scientists work ing together towards a common objective - that of generating a better under standing of the processes involved in nutrient cycling and the development of management regimes which will maintain or enhance long term site productivity.

Download or read book Soil Quality Sustainable Agriculture and Environmental Security in Central and Eastern Europe written by M.J. Wilson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is a crucial component of the economies of many of the countries in transition from a centrally-planned to a market economy and the sector is by no means immune to the environmental and socioeconomic problems confronting the countries as a whole. The concept of sustainable development provides a convenient framework for the formulation of government environmental policy for such countries, especially those of them that aspire to join the EU and would thus be expected to meet EU environmental standards. For agriculture, this inevitably involves appropriate strategies for balancing crop and animal production while protecting the quality of the national soil and water resources. There is thus an urgent need to compile, exchange and evaluate current information on the quality of soils in these countries, and to assess the potential impact of new management practices on the soil and on the wider environment.
Download or read book Living Off the Land in Space written by C Bangs and published by Springer Science & Business Media. This book was released on 2007-06-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a visionary concept for future development of space travel. It describes the enabling technology for future propulsion concepts and demonstrates how mankind will ‘live off the land in space’ in migration from Earth. For the next few millennia at least (barring breakthroughs), the human frontier will include the solar system and the nearest stars. Will it be better to settle the Moon, Mars, or a nearby asteroid and what environments can we expect to find in the vicinity of nearby stars? These are questions that need to be answered if mankind is to migrate into space.
Download or read book Time Resources Society and Ecology written by Tommy Carlstein and published by Routledge. This book was released on 2019-09-18 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1982, Time Resources, Society and Ecology examines and seeks to examine the time dimension in terms of the ecology, technology, social organization and spatial structure of the human habitat. Approaches to time resources – sociological time-budget studies, anthropological activity analysis, and economic analysis of money allocation – have been limited by their sectoral scope or their failure to relate effectively to the processes of social interaction, technological change and environmental structure. In this book, the book’s articulation of time resources is developed in a general theoretical framework of action and interaction in time and space. The book examines constraints and possibilities facing preindustrial societies and throws light on the impact of technology on modern societies. Basic models of time allocation are presented, and, finally, a cross-cultural comparison is made of the mobilization of time resources in preindustrial societies. Geographers, social anthropologists and human ecologists should find this work directly relevant to their interest in understanding the interactions between man and environment.

Download or read book A Framework for K 12 Science Education written by National Research Council and published by National Academies Press. This book was released on 2012-02-28 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.

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.
Download or read book Structure and Change in the Space Economy written by T.R. Lakshmanan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of the space economy demands a keen curiosity supported by a rigorous methodology and a strong sense of the problems at hand. However, the blend of these two capabilities is more unusual than one would be inclined to believe. Professor Martin Beckmann is one of those exceptional scholars whose original theoretical insights and elegant contributions have been crucial to our understanding of the complex mechanism of the space economy. Drawing on the basic social science theory, he has developed a significant body of knowledge which represents fundamental contributions to the fields of location theory, transportation economics, mathematical economics and organizational theory. For over four decades, Martin Beckmann's creativity, originality and excellence in the broad sense of scientific discovery made him play a pivotal and leading role in regional science. A creative artist, Martin Beckmann was never a loner: he not only presented his views in that spare and elegant style we know him by, but also listened. One may say that on these intellectual voyages in the space economy, Martin Beckmann was both a teacher and a pupil. Accompanying him on such a discovery trip was a memorable experience: the final destination was not always defined, but the journey was ever exciting and full of surprises. Some of the great many fellow travellers of Martin Beckmann offer a tribute to a great scientist and professional colleague through this Festschrift.
Download or read book Land Use and Living Space written by Robin H. Best and published by Taylor & Francis. This book was released on 2024-09-02 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few people have any coherent idea of whether the shifts taking place in land-use structure are critically important for us all, or whether they are largely immaterial. This book (originally published in 1981) by setting down a more quantified and carefully researched statement and appraisal of land-use structure and change than had previously been attempted, shows that much of the conventional wisdom about land use can be shown to be incorrect or very suspect. Land-use planning has often been built on the insecure foundation of myth rather than reality, the author maintains. Land Use and Living Space shows that much of the perceived land problem in Britain is not substantiated by evidence on the ground and concludes that there is no real ‘problem’ at all. This analysis was a welcome contribution to the debate during the 1970 and 80s about the true state of land use in Britain, Europe and the USA.
Download or read book Soil and Water Quality at Different Scales written by Peter A. Finke and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated studies on the assessment and improvement of soil and water quality have to deal almost inevitably with issues of scale, since the spatial support of measurements, the model calculations and the presentation of results usually vary. This book contains the selected and edited proceedings of a workshop devoted to issues of scale entitled: `Soil and Water Quality at Different Scales', which was held in 1996 in Wageningen. It is intended for environmental researchers, scientists and MSc and PhD students. Part 1 covers current issues and methodologies with scale related soil and water quality research. Part 2 covers agroecological and hydrological case studies in which scale transforms form an important part of the research chain. Part 3 consists of papers focusing on methodologies and up and downscaling. Part 4 contains review papers based on modellers' and statisticians' considerations as well as the papers and posters presented during the workshop. Part 5 consists of short research notes.
