Available in PDF, EPUB and Kindle. Book excerpt: Sensitive receptors such as soil and fresh bodies of water are at the end of a long chain of events in the process of regional acidification. This chain begins thousands of kilometers upwind at the emitters of acidifying pollutants. The topics covered in this book are important in the study of regional acidification for two reasons. First, it is important to assess the sensitivity of terrestrial and aquatic ecosystems to the deposition of acidifying pollutants. If the sensitivity of an ecosystem is known, then international control strategies can be developed to reduce deposition in the receptor areas of greatest importance. This is an impor tant factor in designing the most effective strategies because of the very high costs of reducing emissions of acidifying pollutants. Second, it is important to be able to predict changes in ecosystems for decades into the future, whether it be an improvement owing to decreases in aci difying emissions or, alas, a further deterioration because control strategies are nonexistent or inadequate. In either event, it is important to be able to judge the results of our actions. Decision makers tend to be mistrustful of models unless they can judge their reliability. The application and testing of the models in Part III of this book cover, therefore, an important facet of model building.

Available in PDF, EPUB and Kindle. Book excerpt: In order to provide meaningful information for evaluating environmental consequences of alternative control strategies of air pollutant emissions, scientists have recently initiated numerous studies aiming at collecting and making use of regional data. New kinds of mathematical models have been developed that no longer are calibrated just for individual stands or catchments but can be applied on a large regional scale. Such regional models and data were reviewed at a meeting" Models to describe the geographic extent and time evolution of acidification and air pollution damage", organized by the Finnjsh Research Project on Acidification (HAPRO), and held in Aulanko, Hiimeenlinna, Finland, July 5-8, 1988. This volume is based on the outcome of that meeting. The chapters of the volume are written by leading scientists in the field. The main objective of this volume is to discuss the potential of regional models to analyze the geographic extent of acidification as well as the environmental damage and the time evolution of:the responses of the environment. First, in Part I of the volume, sensitivity distributions of ecosystems, forest soils and surface waters are described. The focus of interest is therefore extended from the most sensitive ecosystems to sensitive and moderately sensitive parts of the environment. When formulating national and interna tional targets, it is of crucial importance to know the whole distribution of critical loads within the area, and not only the level the most sensitive ecosystem can tolerate.
Download or read book Life Cycle Impact Assessment written by Michael Z. Hauschild and published by Springer. This book was released on 2015-03-24 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a detailed presentation of the principles and practice of life cycle impact assessment. As a volume of the LCA compendium, the book is structured according to the LCIA framework developed by the International Organisation for Standardisation (ISO)passing through the phases of definition or selection of impact categories, category indicators and characterisation models (Classification): calculation of category indicator results (Characterisation); calculating the magnitude of category indicator results relative to reference information (Normalisation); and converting indicator results of different impact categories by using numerical factors based on value-choices (Weighting). Chapter one offers a historical overview of the development of life cycle impact assessment and presents the boundary conditions and the general principles and constraints of characterisation modelling in LCA. The second chapter outlines the considerations underlying the selection of impact categories and the classification or assignment of inventory flows into these categories. Chapters three through thirteen exploreall the impact categories that are commonly included in LCIA, discussing the characteristics of each followed by a review of midpoint and endpoint characterisation methods, metrics, uncertainties and new developments, and a discussion of research needs. Chapter-length treatment is accorded to Climate Change; Stratospheric Ozone Depletion; Human Toxicity; Particulate Matter Formation; Photochemical Ozone Formation; Ecotoxicity; Acidification; Eutrophication; Land Use; Water Use; and Abiotic Resource Use. The final two chapters map out the optional LCIA steps of Normalisation and Weighting.

Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

This book was released on 2012-12-06 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: AND CONCLUSIONS OF THE WARSAW II MEETING ON ATMOSPHERIC COMPUTATIONS TO ASSESS ACIDIFICATION IN EUROPE JOSEPH ALCAMO and JERZY BARTNICKI International Institute for Applied Systems Analysis Schlossplatz 1, A-2361 Laxenburg, Austria (Received June 1, 1988; revised June 20, 1988) Abstract. Three topics are discussed in this report: sensitivity/uncertainty analysis of long range transport models, the interface between atmospheric models of different scales, and linkage between atmospheric and ecological models. In separate analyses oflong range transport models, it was found that uncertainty of annual S deposition was mostly affected by uncertainty of wind velocity, mixing height and wet deposition parameterization. Uncertain parameters collectively caused S deposition errors of around 10-25% (coefficient of variation) in the models examined. The effect of interannual meteorological variability on computed annual S deposition was relatively small. Different methods were presented for combining models of regional and interregional scale. It was found to be more important to include interregional information in regional-scale models for annual computations compared to episodic computations. A variety of linkage problems were noted between atmospheric and ecological models. The vertical distribution of pollutants and 'forest fittering' of pollutant deposition were found to be important in ecological impact calculations but lacking in the output of most interregional atmospheric models.
Download or read book Acidification Research in the Netherlands written by T. Schneider and published by Elsevier. This book was released on 1991-08-21 with total page 787 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the results and conclusions of extensive research on the causes and effects of acidification of forests/forest soils and heathland in the Netherlands. In 1985 the Dutch Priority Programme on Acidification was started in order to give a more concrete form to the increasing interest of policy-makers in the effects of air pollution on ecosystems in particular.In the last three years, the research has focused on obtaining a more accurate estimate of the emission of ammonia on the deposition of SOx, NOy and NHx, and also on quantifying effects on forest and heathland ecosystems. This quantification of effects included experimental work model analyses, and derivation of critical loads and levels for forest and heathland ecosystems. Furthermore, scenario analyses were made with the Dutch Acidification Systems Model (DAS) in order to evaluate the effectiveness of policy measures.The research itself, which formed the basis for this book, has been described in the reports on individual projects. A summary of the scientific results and conclusions is given in thematic reports (added as annex). An independent Review Team has provided a critical assessment of the research carried out since 1988. The Review Report has been incorporated as annex.

Download or read book Acidification Research Evaluation and Policy Applications written by T. Schneider and published by Elsevier. This book was released on 1992-04-24 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large number of nationwide research programmes in the field of acidification have been carried out in the last decade. Especially in Western Europe, extensive programmes have resulted in a good overview of all the effects - mostly negative - caused by acidifying substances. There is now consensus that types of acidification damage relate to the unique geography of an area: air pollution affects vegetation; acid aerosol the ozone layer. New in this volume, is the relation between scientific results of integrated research programmes and policy actions to prevent, reduce and limit the widespread damage caused by acidification. The results of many different national research programmes are evaluated and compared to present a unique compilation for the research scientist and policy maker. In this volume thematic reviews on specific topics of acidification research are presented, followed by overviews of acidification policy plans and actual abatement plans. The result is the best review of acidification research carried out worldwide during the last decade and presentation of the critical relation between research results and policy actions.

Available in PDF, EPUB and Kindle. Book excerpt: Many books instruct readers on how to use the tools of policy analysis. This book is different. Its primary focus is on helping readers to look critically at the strengths, limitations, and the underlying assumptions analysts make when they use standard tools or problem framings. Using examples, many of which involve issues in science and technology, the book exposes readers to some of the critical issues of taste, professional responsibility, ethics, and values that are associated with policy analysis and research. Topics covered include policy problems formulated in terms of utility maximization such as benefit-cost, decision, and multi-attribute analysis, issues in the valuation of intangibles, uncertainty in policy analysis, selected topics in risk analysis and communication, limitations and alternatives to the paradigm of utility maximization, issues in behavioral decision theory, issues related to organizations and multiple agents, and selected topics in policy advice and policy analysis for government.

Download or read book Assessments of Regional and Global Environmental Risks written by Alexander E. Farrell and published by Routledge. This book was released on 2010-09-30 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: As environmental challenges grow larger in scale and implications, it is increasingly important to apply the best scientific knowledge in the decisionmaking process. Editors Farrell and Jäger present environmental assessments as the bridge between the expert knowledge of scientists and engineers on the one hand and decisionmakers on the other. When done well, assessments have a positive impact on public policy, the strategic decisions of private firms, and, ultimately, the quality of life for many people. This book is the result of an international, interdisciplinary research project to analyze past environmental assessments and understand how their design influenced their effectiveness in bringing scientific evidence and insight into the decisionmaking process. The case studies in the book feature a wide range of regional and global risks, including ozone depletion, transboundary air pollution, and climate change. Assessments of Regional and Global Environmental Risks offers several important contributions. It provides a clear account of the choices faced in the design of environmental assessments and a clear description of the lessons learned from past assessments. It illustrates why assessments are social processes, not simply reports. And, while they identify no universal, one-size-fits-all design, the authors find that, to be effective, environmental assessments must be viewed by those who produce and use them as being salient; credible in their scientific support; and legitimate, or fair in design and execution.
