This book was released on 2009 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological indicators address ecosystems structure and/or function and are commonly used to provide synoptic information about their state. Through quantitative representations of either the forces that steer ecosystems, responses to forcing functions, or of previous, current, or future states of an ecosystem, indicators are expected to reveal conditions and trends that will help in development planning and decision making processes. Ecological indicators combine numerous environmental factors in a single value, which may be useful in terms of management and in the development of ecological concepts, compliant with the general public's understanding. Nevertheless, their application is not exempt of criticisms, the first of which is that aggregation results in an oversimplification of the ecosystem under observation. Ecological indicators must therefore be handled following the right criteria and in situations that are consistent with its intended use and scope; otherwise they may drive to confusing interpretations of data.

This book was released on 2000-05-12 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental indicators, such as global temperatures and pollutant concentrations, attract scientists' attention and often make the headlines. Equally important to policymaking are indicators of the ecological processes and conditions that yield food, fiber, building materials and ecological "services" such as water purification and recreation. This book identifies ecological indicators that can support U.S. policymaking and also be adapted to decisions at the regional and local levels. The committee describes indicators of land cover and productivity, species diversity, and other key ecological processesâ€"explaining why each indicator is useful, what models support the indicator, what the measured values will mean, how the relevant data are gathered, how data collection might be improved, and what effects emerging technologies are likely to have on the measurements. The committee reviews how it arrived at its recommendations and explores how the indicators can contribute to policymaking. Also included are interesting details on paleoecology, satellite imagery, species diversity, and other aspects of ecological assessment. Federal, state, and local decision-makers, as well as environmental scientists and practitioners, will be especially interested in this new book.

This book was released on 2006 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the environment of North America is not dissected by political borders, Canada and the United States often measure environmental conditions and report on them using different indicators. This report examines the environmental indicators used by both nations, and based on analysis of current research into common methodologies used in national, regional and global environmental reporting, it goes on to draw lessons for the development of bilateral indicators to cover the North American region.

Download or read book A New Ecology written by Sven Erik Jørgensen and published by Elsevier. This book was released on 2011-08-30 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New Ecology presents an ecosystem theory based on the following ecosystem properties: physical openness, ontic openness, directionality, connectivity, a complex dynamic for growth and development, and a complex dynamic response to disturbances. Each of these properties is developed in detail to show that these basic and characteristic properties can be applied to explain a wide spectrum of ecological obsevations and convections. It is also shown that the properties have application for environmental management and for assessment of ecosystem health.* Demonstrates an ecosystem theory that can be applied to explain ecological observations and rules* Presents an ecosystem theory based upon a systems approach* Discusses an ecosystem theory that is based on a few basic properties that are characteristic for ecosystmes

Available in PDF, EPUB and Kindle. Book excerpt: In order to assist Environment Canada in environment planning, a workshop was convened in May 1987. The speakers and the working groups addressed selection criteria for indicators at different levels of ecosystem organization, and identified the important variables that should be measured for the sustainable management of renewable natural resources. Following the workshop, case studies on different types of indicators, as well as on novel monitoring programs, were commissioned.
Download or read book Indicators of Environmental Quality written by William A. Thomas and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers and agencies collect reams of objective data and authors publish volumes of subjective prose in attempts to explain what is meant by environmental quality. Still, we have no universally recognized methods for combining our quantitative measures with our qualitative concepts of environ ment. Not all of our environmental goals should be reduced to mere numbers, but many of them can be; and without these quantitative terms, we have no way of defining our present position nor of selecting positions we wish to attain on any logically established scale of environmen tal values. Stated simply, in our zeal to measure our environment we often forget that masses of numbers describing a system are insufficient to understand it or to be used in selecting goals and priorities for expending our economic and human resources. Attempts at quantitatively describing environmental quality, rather than merely measuring different environmental variables, are relatively recent. This condensing of data into the optimum number of terms with maximum information content is a truly interdisciplinary challenge. When Oak Ridge National Laboratory initiated its Environmental Program in early 1970 under a grant from the National Science Foundation, the usefulness of environmental indicators in assessing the effects of technology was included as one of the initial areas for investigation. James L. Liverman, through his encouragement and firm belief that these indicators are indispensable if we are to resolve our complex environmental problems, deserves much of the credit for the publication of this book.
Download or read book Sustainability Indicators written by Tomás Hák and published by Island Press. This book was released on 2012-09-26 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the concept of sustainability has been widely embraced, it has been only vaguely defined and is exceedingly difficult to measure. Sustainability indicators are critical to making the broad concept of sustainability operational by providing specific measures by which decision makers and the public can judge progress. Sustainability Indicators defines the present state of the art in indicator development. It presents a comprehensive assessment of the science behind various indicators, while placing special emphasis on their use as communications tools. The contributors draw on their experience as academics and practitioners to describe the conceptual challenges to measuring something as complex as sustainability at local, regional, national, and global scales. The book also reviews existing indicators to assess how they could be better employed, considering which indicators are overused and which have been underutilized. Sustainability Indicators will help planners and policy makers find indicators that are ready for application and relevant to their needs, and will help researchers identify the unresolved issues where progress is most urgently needed. All readers will find advice as to the most effective ways to use indicators to support decision making.

Book excerpt: Encyclopedia of the Anthropocene, Five Volume Set presents a currency-based, global synthesis cataloguing the impact of humanity’s global ecological footprint. Covering a multitude of aspects related to Climate Change, Biodiversity, Contaminants, Geological, Energy and Ethics, leading scientists provide foundational essays that enable researchers to define and scrutinize information, ideas, relationships, meanings and ideas within the Anthropocene concept. Questions widely debated among scientists, humanists, conservationists, politicians and others are included, providing discussion on when the Anthropocene began, what to call it, whether it should be considered an official geological epoch, whether it can be contained in time, and how it will affect future generations. Although the idea that humanity has driven the planet into a new geological epoch has been around since the dawn of the 20th century, the term ‘Anthropocene’ was only first used by ecologist Eugene Stoermer in the 1980s, and hence popularized in its current meaning by atmospheric chemist Paul Crutzen in 2000. Presents comprehensive and systematic coverage of topics related to the Anthropocene, with a focus on the Geosciences and Environmental science Includes point-counterpoint articles debating key aspects of the Anthropocene, giving users an even-handed navigation of this complex area Provides historic, seminal papers and essays from leading scientists and philosophers who demonstrate changes in the Anthropocene concept over time

Book excerpt: Algae are an important component of aquatic benthic ecosystems because they reflect the health of their environment through their density, abundance, and diversity. This comprehensive and authoritative text is divided into three sections to offer complete coverage of the discussion in this field. The first section introduces the locations of benthic algae in different ecosystems, like streams, large rivers, lakes, and other aquatic habitats. The second section is devoted to the various factors, both biotic and abiotic, that affect benthic freshwater algae. The final section of the book focuses on the role played by algae in a variety of complex freshwater ecosystems. As concern over environmental health escalates, the keystone and pivotal role played by algae is becoming more apparent. This volume in the Aquatic Ecology Series represents an important compilation of the latest research on the crucial niche occupied by algae in aquatic ecosystems. - Presents algae as the important player in relation to environmental health - Prepared by leading authorities in the field - Includes comprehensive treatment of the functions of benthic algae as well as the factors that affect these important aquatic organisms - Acts as an important reference for anyone interested in understanding and managing freshwater ecosystems
Download or read book In Search of Indicators of Sustainable Development written by Onno J. Kuik and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1989 the Dutch government published a National Environmental Policy Plan (Dutch abbreviation NMP). This NMP is based on the book Concern for Tomorrow. a national environmental survey by RIVM (the National Institute of Public Health and Environmental Protection). A major conclusion of the RIVM study was that emissions of many pollutants had to be cut by 70 - 90 % in order to reach environmental quality goals. The government accepted the RIVM analysis and consequently ClUTent Dutch environmental policy aims at large reduction of pollutants. Another conclusion of the RIVM study was that such high reduction goals would not be easy to achieve by technological means alone, and that thus structural changes would be required. These changes could eventually lead to sustainable development, which now forms the major focus of Dutch government national environmental policy. This being so, the Dutch government requested that RIVM in subsequent issues of Concern for Tomorrow should investigate the options for sustainable development.
