Book Description
With contributions from economists, ecologists, and government agency professionals, this book provides a multidisciplinary approach to environmental decision at a watershed level. It integrates ecological risk assessment (ERA) and economic analysis to improve environmental management in a diversity of watersheds. It includes different points of view concerning the extent to which each study achieves an ideal framework for the integration of ERA and economic analysis. With a practical focus on real-world decisions, it includes the effects of urban development, mining, and water withdrawal for agriculture and also evaluates the socioeconomic and institutional dimensions of decision making.

Book Description
Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

Book Description
Most ecological risk assessments consider the risk to individual organisms or organism-level attributes. From a management perspective, however, risks to population-level attributes and processes are often more relevant. Despite many published calls for population risk assessment and the abundance of available scientific research and technical tool

Book Description
The identification and prioritization of multiple watershed stressors and the corresponding development of optimal management strategies remains a challenge in ecological risk assessment. Eco-epidemiological analysis of archival environmental spatial databases integrates available biological, physical and chemical information to generate hypotheses based on stressor-response data relationships. A geographic information systems-based technique incorporating Bayesian weights-of-evidence analysis and weighted logistic regression (WOE/WLR) developed for and currently utilized in minerals exploration was extrapolated to the eco-epidemiological analysis of aquatic ecosystem data. Case studies within state of Ohio (USA) and England and Wales were conducted to demonstrate a method proof-of-concept in the context of various concepts relevant ecological risk assessment such as biological endpoint selection, geographic scale, land use characterization, and temporal variability. Analysis results were communicated as quantitative estimates of stressor influence and impairment probability maps with significant model fit to observed data. Stressor identification, influence and estimated impairment probability varied across levels of biological organization, study area extent, land use intensity, and seasonal conditions. WOE/WLR results yielded quantitative evidence for the importance of consideration of environmental complexity in ecological risk assessment, and were consistent with both biological plausibility and examples from the literature. Validation of WOE/WLR stressor hypotheses was additionally evaluated by cross-comparison to an independent eco-epidemiological database method and to various field-based assessments. A methodological framework for the development and application of WOE/WLR for eco-epidemiological research is proposed to enhance screening-level (Tier 1) ecological risk assessment.

Book Description
This publication is a practical guidebook on environmental risk assessment, especially for watershed-scale management. It highlights case studies of watershed environmental risk in Malaysia, including the potential health risks as well as screening methods and management in practice. In order to apply environmental risk assessment methods for the management of toxic chemicals, it is necessary to consider the geological and climate features of each country as well as their cultural characteristics. Focusing on Malaysia as a representative country, the book also discusses studies in other Asian countries. The insights provided can be applied to advanced and developing countries alike. A suitable textbook for graduate students, it is also a valuable reference source for researchers, practitioners and policymakers.

Book Description
An important guide to assessing and managing the environment from a landscape perspective Ecological relationships are nested within the landscape. Identifying the relevant spatial and temporal scales is critical for an effective understanding of ecological functions that human societies depend upon. Moreover, human encroachment into natural areas, or changes in climate, can alter spatial relationships, which in turn can negatively affect vital plant and wildlife patterns—and weaken economic structures needed to sustain human societies. This book is the first to combine multiple disciplines into one cohesive strategy to study these crucial connections, and looks toward building a social paradigm that embraces the dynamics of ecological systems. This book: Integrates landscape ecology, environmental risk assessment, valuation of ecological goods and services, and environmental management decision processes into one single source Includes chapters on quantitative measures, Bayesian modeling,¿economic analysis, and sustainable landscapes Covers marine, forest, agricultural, and pharmaceutical risk assessment Has a chapter on predicting climate change risk to ecosystems Has a companion ftp site with color graphics, animations, and risk assessment tools With material that is accessible across all knowledge levels, Environmental Risk Assessment and Management from a Landscape Perspective moves beyond looking solely at chemical contaminants to diagnose environmental threats, and aims to accomplish practical risk assessment in a manner that supports long-term sustainable management.
