In this title, originally published in 1984, Wilman develops and describes a methodology for imputing a monetary value to the loss in beach recreational services that would result from a hypothetical oil spill in the Georges Bank area off Massachusetts. Combining an oil-spill risk analysis model with an hedonic pricing model to generate estimates of beach pollution costs associated with offshore oil development, Wilman makes possible for the first time a rational judgement regarding whether the benefits of developing offshore oil outweigh the costs. This book is a valuable resource for students interested in environmental studies and Wilman's methodological approach can be used to value other nonmarket resource services in any area.

Recent developments in air pollution modelling are explored as a series of contributions from researchers at the forefront of their field.

It consists of a series of papers that were presented at the 30th NATO/SPS International Technical Meeting on Air Pollution Modelling and its Application held in San Francisco, U.S.A., May 18-22, 2009. It is intended as reference material for students and professors interested in air pollution modelling at the graduate level as well as researchers and professionals involved in developing and utilizing air pollution models.

Huge quantities of natural resources are illegally harvested and their proceeds laundered in the Asia-Pacific region, fostering corruption and undermining environmental governance. Most illegal exploitation and pollution occurs in countries with poor governance capacities, but much of the sale for profit and money laundering occurs in mature markets with well-developed governance capacities. Their asymmetrical enforcement capacities can complement each other.

This book explores ways to combat illegal fishing and logging in Asia-Pacific region by the use of cooperative legal measures, particularly anti-money laundering and confiscation of proceeds techniques. Contributors to this volume cover themes including: the nature of transnational environmental crime; patterns in laundering of illicit fish and forest products; networks for distribution of illicit products; weaknesses in current systems for assurance of the legality of products; and international legal cooperation to enforce anti-money laundering laws in relation to illicit products. In considering these topics the book explores how the innovative use of anti-money laundering measures and the seizure of criminal proceeds can as policy options to combat transnational fishery and forestry crimes.

The book will be of keen interest to scholars and students of environmental law and criminal law, and excellent use for practitioners in natural resources conservation law.

The global carbon markets are growing at a staggering rate. The growth prospects for business are enormous and the potential positive impacts for greenhouse gas emission reductions, climate policy options, renewable energy investment, development projects and efficiency gains are increasingly apparent.

Satellite imagery and data are widely used in public health surveillance to provide early warning of disease outbreaks and for averting pandemics. Convergence of these technologies began in the 1970s and has gained wide acceptance in the 21st Century. Environmental Tracking for Public Health Surveillance focuses on the expanding use of satellite sensor imagery and long-term spectral measurements for assessing and modelling Earth's environments in context of public health surveillance. It addresses vector-borne, air-borne, water-borne, and zoonotic diseases, and explores analytical methods for forecasting environmental conditions and their potential for consequent disease outbreaks. Infectious and contagious diseases are of particular interest in this volume because once parasite-vector-human host pathways are triggered by favourable biological circumstances, pandemic diseases can spread to global scale in a matter of hours. The chapters advance readers through three sets of material. Part I reviews the 1970-2012 history of satellite Earth-science surveillance technology that led to linking natural environments to human diseases, and more generally to public health applications. Part II describes specific infectious and contagious diseases and the threat of emerging and re-emerging diseases. Part III explores the kinds of satellite data, modelling, and electronic information systems being developed to expedite health intercessions and responses at local to regional and global scales of reference. Equally important are the extensive reference sections for chapters in Parts II and III. For readers interested in tracking the development of Earth-science technology, these constitute a thorough entree to both the health and environmental literature. The chapters are written jointly by experts in both the health and Earth-science technologies. Each chapter is accompanied by an extensive list of citations to provide background and validation of the current state-of-the-art for a variety of high-interest human diseases and associated health and well-being issues. The importance of day-to-day weather patterns, the impacts of severe weather events and longer-term climate cycles form the basis for developing information systems that meet goals and expectations of national and international health monitoring bodies. Environmental Tracking for Public Health Surveillance provides a state-of-the-art overview on how environmental tracking data from satellite, airborne, and ground-based sensors are being integrated into appropriate geophysical and spatial information system models to enhance public health surveillance and decision-making from local to global levels, and is intended primarily for a cross-disciplinary professional audience consisting of public health decision-makers, spatial data analysts, modelers, Earth observation specialists, and medical researchers.

Scientists and consultants need to estimate and map properties of the terrestrial environment. These include plant nutrients and parasites in soil, gaseous emissions from soil, pollutant metals and xenobiotics in waste and contaminated land, salt in groundwater and species abundances above ground. The scale varies from small experimental plots to catchments, and the land may be enclosed in fields or be open grassland, forest or desert. Those who sample the variables to obtain the necessary data need guidance on the design and analysis of sampling methods for their conclusions and recommendations to be valid.

This book provides that guidance, backed by sound rationale and statistical theory. It concentrates on design-based sampling for estimates of mean values of environmental properties, emphasizing replication and randomization. It starts with simple random sampling and then progresses to more efficient designs, such as spatially stratified random sampling, stratification by classes and cluster sampling. It includes a section on purposive sampling in classical soil survey, which is relevant to other environmental properties such as vegetation. It also describes the effects of bulking on errors and the use of ancillary information and regression to improve estimates. The authors draw the important distinction between design-based sampling for estimating means and model-based methods (geostatistics) for local spatial prediction and mapping, and focus on the latter. They describe designs suitable for computing variograms and prediction by kriging, as well as a staged approach, so that sampling is neither inadequate nor excessive, and designs adapt as knowledge is accumulated. Including numerous worked case studies of sampling in agriculture, ecology and environmental science, the book will be of immediate practical value.

The fate of much of the world's terrestrial biodiversity depends upon our ability to improve the management of forest ecosystems that have already been substantially modified by humans. Monitoring is an essential ingredient in meeting this challenge, allowing us to measure the impact of different human activities on biodiversity and identify more responsible ways of managing the environment. Nevertheless many biodiversity monitoring programs are criticised as being little more than 'tick the box' compliance exercises that waste precious resources and erode the credibility of science in the eyes of decision makers and conservation investors. The purpose of this book is to examine the factors that make biodiversity monitoring programs fail or succeed. The first two sections lay out the context and importance of biodiversity monitoring, and shed light on some of the key challenges that have confounded many efforts to date. The third and main section presents an operational framework for developing monitoring programs that have the potential to make a meaningful contribution to forest management. Discussion covers the scoping, design and implementation stages of a forest biodiversity monitoring program, including defining the purpose, goals and objectives of monitoring, indicator selection, and the process of data collection, analysis and interpretation. Underpinning the book is the belief that biodiversity monitoring should be viewed not as a stand-alone exercise in surveillance but rather as an explicit mechanism for learning about how to improve opportunities for conservation. To be successful in this task, monitoring needs to be grounded in clear goals and objectives, effective in generating reliable assessments of changes in biodiversity and realistic in light of real-world financial, logistical and social constraints.

WATER RESOURCES AND ENVIRONMENT provides a detailed introduction to the full range of advanced, multidisciplinary techniques used in the study of water resources from understanding individual aquifers to the protection and management of water in a sustainable way, compatible with the preservation of the environment. Based on a masters course from UNESCO's International Hydrological Program, this textbook is accompanied by color figures and graphics, illustrating clearly the content of the text and showing real examples from the field. Each chapter also contains a list of exercises and practical activities as well as case studies.

Groundwater is sometimes called "the hidden asset" - awareness of its existence and its importance is not well known and as a consequence the measures which are required to protect and manage it in an environmental sustainable way are either not taken or are taken too late. Where pollution has occurred and measures are taken too late it may take decades, or longer, until the necessary restoration of quality is achieved.

This comprehensive text presents in the following sections:

Groundwater monitoring in the regulatory and international contextConceptual modelling and network designGroundwater pollutants and other pressuresGroundwater quality standards and trend assessmentCase studies for groundwater assessment and monitoring in the light of EU legislationGroundwater measurementsAssociating external stakeholders

The editors have collected state-of-the-art information on groundwater quality assessment monitoring from the international community, providing further stimulation to the work of all parties involved in the challenges this area creates to ensure sound quality assessment of groundwater.

Under the best of circumstances, preparing an environmental impact assessment (EIA) can be a complex and challenging task. Experience indicates that the scope and quality of such analyses varies widely throughout the U.S. as well as internationally. Written to help practitioners and decision-makers apply best professional practices in the development of EIAs, Environmental Impact Assessment: A Guide to Best Professional Practices provides an in depth, yet practical direction for developing a defensible analysis that meets best professional practices. The book describes preparation of five distinct types of assessments: Cumulative Impact Assessment (CIA) Preparing Greenhouse Emission Assessments Preparing Risk Assessments and Accident Analyses Social Impact Assessment (SIA) and Environmental Justice The International Environmental Impact Assessment Process Guiding Principles To date, there is significant variation and disagreement about how such analyses should be prepared. The author introduces best professional practices (BPP) for preparing such EIAs that is intended to meet decision-making and regulatory expectations. He supplies a comprehensive and balanced skill set of tools, techniques, concepts, principles, and practices for preparing these assessments. He also includes directions for developing a comprehensive Environmental Management Systems which can be used to monitor and implement final decisions for such analyses. While the book references the U.S. National Environmental Policy Act (NEPA), most of this guidance is generally applicable to any international EIA process consistent with NEPA. With thorough coverage of all aspects of assessments, the book presents a theoretical introduction to the subject as well as practical guidance. It delivers state-of-the-art tools, techniques, and approaches for resolving EIA problems.

Environmental applications have long been a core use of GIS. However, the effectiveness of GIS-based methods depends on the decision-making frameworks and contexts within which they are employed. GIS for Environmental Decision-Making takes an interdisciplinary look at the capacities of GIS to integrate, analyze, and display data on which decisions must be based. It provides a broad prospective on the current state of GIS for environmental decision-making and emphasizes the importance of matters related to data, analysis, and modeling tools, as well as stakeholder participation. The book is divided into three sections, which effectively relate to three key aspects of the decision-making process as supported by GIS: data required, tools being developed, and aspects of participation. The first section stresses the ability to integrate data from different sources as a defining characteristic of GIS and illustrates the benefits that this can bring in the context of deriving land-use and other information. The second section discusses a range of issues concerning the use of GIS for suitability mapping and strategic planning exercises, through illustrative examples. The last section of the book focuses on the use of GIS-based techniques to facilitate public participation in decision-making processes. In particular, it provides an overview of developments in this area, concentrating on how GIS, modeling, and 3D landscape visualization techniques are gradually achieving closer integration. Given the complex challenges presented by global environmental change, GIS for Environmental Decision-Making provides a clear illustration of how the use of GIS can make significant contributions to trans-disciplinary initiatives to address environmental problems.

The book reviews the current state of knowledge on the chemical and physical processes occurring in the environmental media (i) the atmosphere, (ii) the aqueous phase and (iii) soil and identifies the strengths and weaknesses of the chemical mechanisms (both explicit and condensed) currently available to simulate the multimedia environmental chemistry of volatile organic compounds (VOCs) and particulate matter in these media. Contributions examine how well this knowledge has been incorporated into different types of CT models and appraise the current status and significant issues in the development and usage of the models. Model simulations of some real world chemical perturbations to the Earth system are presented which appraise the performance of the models in relation to "real world" observations. Serious caveats in our understanding of chemical processes and their simulation in the various compartments of the Earth system are highlighted and areas are identified that need urgent improvement, in particular with respect to environmental security.

This title meets a great demand for training in spatial analysis tools accessible to a wide audience. Landscape ecology continues to grow as an exciting discipline with much to offer for solving pressing and emerging problems in environmental science. Much of the strength of landscape ecology lies in its ability to address challenges over large areas, over spatial and temporal scales at which decision-making often occurs. As the world tackles issues related to sustainability and global change, the need for this broad perspective has only increased. Furthermore, spatial data and spatial analysis (core methods in landscape ecology) are critical for analyzing land-cover changes world-wide. While spatial dynamics have long been fundamental to terrestrial conservation strategies, land management and reserve design, mapping and spatial themes are increasingly recognized as important for ecosystem management in aquatic, coastal and marine systems. This second edition is purposefully more applied and international in its examples, approaches, perspectives and contributors. It includes new advances in quantifying landscape structure and connectivity (such as graph theory), as well as labs that incorporate the latest scientific understanding of ecosystem services, resilience, social-ecological landscapes, and even seascapes. Of course, as before, the exercises emphasize easy-to-use, widely available software. http://sarahgergel.net/lel/learning-landscape-ecology/

This book proposes the concept of urban multiple habitats and then analyzes its corresponding classification, function and potential supply capability. It provides an analysis framework for studying the relationship between urban biodiversity and built environment, and for considering the loss of urban habitats caused by high-density development. It argues that urban biodiversity is a key indicator for assessing urban ecosystem services. On this basis, the book then presents a case study mainly focusing on wild birds in Shanghai, as urban wild birds and their species could be viewed as an essential indicator for evaluating healthy ecosystem of contemporary cities. Based on the empirical findings, the book proposes an assessment model for urban biodiversity performance and a range of principles, strategies and key indicators regarding the optimization of urban planning and design practice to enhance urban biodiversity performance.

There is evidence that the world has been witnessing more intense tropical cyclones. Accompanying these tropical cyclones are heightened levels of devastation that witness the loss of human life and wildlife, destruction of natural resources and property and the disruption of major economic and social activities. To this end, there is a growing demand for publications focusing on tropical cyclones at various levels that include regional, national and local levels, especially from Africa. One sub-region that has been witnessing the harsh realities of the increasing intensity of tropical cyclones in southern Africa. However, within this region, countries are usually impacted at varying degrees of damage. Among the countries that usually encounter the harshness of these tropical cyclones are the Comoros, Botswana, Madagascar, Mauritius, Malawi, Mozambique, Reunion, the Seychelles, South Africa and Zimbabwe. From the history books, the following tropical cyclones made landfall and hit southern Africa: Eline (2000), Favio (2007), Dineo (2017), Idai (2019), Kenneth (2019), Eliose (2021), and Chalane (2020). Although all these tropical cyclones had negative impacts, it is undoubtedly Tropical Cyclone Idai that shocked the world with its devastation mainly in Mozambique, Malawi and Zimbabwe in March 2019. Key infrastructure was destroyed, livelihoods were lost, and the environment was degraded. Thousands of people died, many more were injured, many remain unaccounted for and others remained homeless as of the time of finalising this book in February 2021. This book, therefore focuses on the devastating impacts of Tropical Cyclone Idai in Zimbabwe. The book interfaces Tropical Cyclone Idai's impacts with the 2030 Agenda for Sustainable Development and some of the 17 Sustainable Development Goals (SDGs). This linkage was deliberate given that there is still time remaining until 2030, and the world has generally agreed to move into the future along the pathways of sustainable development and sustainability. The book adds to the first comprehensive profiling of the impacts of tropical cyclones on southern African economies, particularly that of Zimbabwe. It also comes up as the first in a three-volume series. The other volumes to look out for are Cyclones in Southern Africa Vol 2: Foundational and Fundamental Topics; and Cyclones in Southern Africa Vol 3: Implications for the Sustainable Development Goals. To this end, this book is suitable as a read for several professionals and disciplines such as tourism and hospitality studies, economics, sustainable development, development studies, environmental sciences, arts, geography, life sciences, politics, planning and public health.

The second chapter introduces the texture and a detailed literature survey citing papers related to texture analysis and image processing. The third chapter describes basic texture models for gray level images and multivariate texture models for color or remotely sensed images with relevant Matlab source codes. The fourth chapter focuses on texture-based classification and texture-based segmentation. The Matlab source codes for performing supervised texture based segmentation using basic texture models and minimum distance classifier are listed. The fifth chapter describes supervised and unsupervised classifiers. The experimental results obtained using a basic texture model (Uniform Local Binary Pattern) with the classifiers described earlier are discussed through the relevant Matlab source codes. The sixth chapter describes land cover classification procedure using multivariate (statistical and spectral) texture models and minimum distance classifier with Matlab source codes. A few performance metrics are also explained. The seventh chapter explains how texture based segmentation and land cover classification are performed using the hidden Markov model with relevant Matlab source codes. The eighth chapter gives an overview of spatial data analysis and other existing land cover classification methods. The ninth chapter addresses the research issues and challenges associated with land cover classification using textural approaches. This book is useful for undergraduates in Computer Science and Civil Engineering and postgraduates who plan to do research or project work in digital image processing. The book can serve as a guide to those who narrow down their research to processing remotely sensed images. It addresses a wide range of texture models and classifiers. The book not only guides but aids the reader in implementing the concepts through the Matlab source codes listed. In short, the book will be a valuable resource for growing academicians to gain expertise in their area of specialization and students who aim at gaining in-depth knowledge through practical implementations. The exercises given under texture based segmentation (excluding land cover classification exercises) can serve as lab exercises for the undergraduate students who learn texture based image processing.

Indicators are more and more applied to describe and analyze complex systems. Typical examples: Innovation potential of nations, child-well being, Environmental health, poverty, chemical pollution, corruption of nations. The task is: How can a system of indicators be defined in order to fulfill the above expectations. One possibility is the application of the mathematical theory of partial order, especially when the indicator system shall be used for ranking purposes.

This book employs a suite of remotely sensed products and advanced technologies to provide the first comprehensive space-based sensing of Lake Victoria, the world's second largest freshwater lake that supports a livelihood of more than 42 million people, modulates regional climate, but faces myriads of challenges. Proper understanding of the lake and changes in its physical dynamics (e.g., water level, shorelines and areal dynamics) resulting from the impacts of climate variation and climate change as well as anthropogenic (e.g., hydropower and irrigation) is important for its management as well as for strategic development before, during and after climate extremes (e.g., floods and droughts) in order to inform policy formulations, planning and mitigation measures. Owing to its sheer size, and lack of research resources commitment by regional governments that hamper its observations, however, it is a daunting task to undertake studies on Lake Victoria relying solely on in-situ "boots on the ground" measurements, which are sparse, missing in most cases, inconsistent or restricted by governmental red tapes. To unlock the potentials of Lake Victoria, this book argues for the removal of obsolete Nile treaties signed between Britain, Egypt and Sudan in the 1920s and 1950s, which prohibits its utilization by the upstream countries. The book is useful to those in water resources management and policy formulations, hydrologists, environmentalists, engineers and researchers. In a unique cross-disciplinary approach, the Book articulates the various climatic impacts and explanations from natural and anthropogenic origins, which affected Lake Victoria and its vicinity, including the drastic increase and depletion of water level in the Lake and dams, floods and droughts, water quality/security, crop health, food security, and economic implications. With no exception as in his many publications, Joseph L. Awange used data analysis methodologies including filtering, adjustment theory, and robust statistics, to quantify the hydrologic and other parameters, and their estimated uncertainties. The Book is recommended for readers from a diverse disciplines, including physical and social sciences, policy, law, engineering, and disaster management. Professor C.K. Shum, Ohio State University.
