This important Handbook is an essential guide to the state-of-the-art concepts, debates and innovative practices in the field of cumulative impact assessment. It helps to strengthen the foundations of this challenging field, identify key issues demanding solutions and summarize recent trends in forward progress, particularly through the use of illustrative case examples.
Marine mammals face a large array of stressors, including loss of habitat, chemical and noise pollution, and bycatch in fishing, which alone kills hundreds of thousands of marine mammals per year globally. To discern the factors contributing to population trends, scientists must consider the full complement of threats faced by marine mammals. Once populations or ecosystems are found to be at risk of adverse impacts, it is critical to decide which combination of stressors to reduce to bring the population or ecosystem into a more favorable state. Assessing all stressors facing a marine mammal population also provides the environmental context for evaluating whether an additional activity could threaten it. Approaches to Understanding the Cumulative Effects of Stressors on Marine Mammals builds upon previous reports to assess current methodologies used for evaluating cumulative effects and identify new approaches that could improve these assessments. This review focuses on ways to quantify exposure-related changes in the behavior, health, or body condition of individual marine mammals and makes recommendations for future research initiatives.
This study reviews current practices for identifying and assessing cumulative effects in order to formulate recommendations that the Canadian Environmental Assessment Research Council (CEARC) may use in drafting a research prospectus. A preliminary analytical framework for assessing CEA is presented, and 3 case studies documenting Canadian experience with assessing and managing cumulative effects are examined.
The book is comprised of practical environmental and socioeconomic information which can be used in planning and implementing CEAM studies. Such information has been compiled from CEAM practices in the USA, Canada, Australia, European, and many other countries. Considerable information on step-wise CEAM processes, along with connector methods and resource-related methods and tools for predicting, mitigating, and managing cumulative effects on key Valued Ecosystem Components (VECs), is included.
Cumulative effects of multiple environmental perturbations of natural and social systems were identified as needing study because of a lack of a clear and unambiguous definition of cumulative effects assessment, despite the widespread recognition of its importance. There is increasing concern that neither scientists nor institutions work at the temporal and spatial scales needed for the assessment of cumulative effects. The workshop explored these issues, identified current scientific and management techniques of dealing with cumulative effects, and to recommended research and management priorities for improving the management of cumulative effects.
Globally, environmental impact assessment (EIA) is one of the most enduring and influential environmental management tools. This handbook provides readers with a strong foundation for understanding the practice of EIA, by outlining the different types of assessment while also providing a guide to best practice. This collection deploys a research and practice-based approach to the subject, delivering an overview of EIA as an essential and practical tool of environmental protection, planning, and policy. To best understand the most pertinent issues and challenges surrounding EIA today, this volume draws together prominent researchers, practitioners, and young scholars who share their work and knowledge to cover two key parts. The first part introduces EIA processes and best practices through analytical and critical chapters on the stages/elements of the EIA process and different components and forms of assessment. These provide examples that cover a wide range of assessment methods and cross-cutting issues, including cumulative effects assessment, social impact assessment, Indigenous-led assessment, risk assessment, climate change, and gender-based assessment. The second part provides jurisdictional reviews of the European Union, the US National Environmental Policy Act, recent assessment reforms in Canada, EIA in developing economies, and the EIA context in England. By providing a concise outline of the process followed by in-depth illustrations of approaches, methods and tools, and case studies, this book will be essential for students, scholars, and practitioners of environmental impact assessment.
