Coastal And Estuarine Environments

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.

The coast cannot be left to nature to determine its fate. Wealth, property, economic interests, recreation, tourism and wildlife are all threatened. Coasts are an administrative battle ground and one of the most important and widely examined topics in environmental management. Coastal and Estuarine Management examines the issues surrounding the human use and abuse of estuarine and coastal environments. Emphasising the importance and significance of this natural resource, the uses and conflicts which occur and the results of human activity, this book explains the ways in which conservation and management policies and practices can protect this productive and diverse ecosystem. Examples and real-life case studies illustrate the effect of human intervention, both from an historic and contemporary perspective. Exposing the environmental consequences of estuarine pollution, Peter French highlights the need for management strategies to promote a sustainable development ethic for estuaries.

The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Estuaries and their surrounding wetland regions are among the most productive ecosystems in the world, with more than half of humanity inhabiting their shores. Anthropogenic factors make estuaries highly susceptible to ecosystem degradation. Coastal waters are closely connected with human activity, and their dynamic processes may greatly affect coastal environments. This book provides a compendium of studies on estuarine dynamics, river plumes, and coastal water dynamics, studies that have investigated the changes in estuarine and coastal zones in response to sea-level rise and other environmental factors, and policy and management strategies to ensure the health and economy of coastal zones. This book aims to display novel frontiers in these fields and may help to inspire in-depth studies in the future.

For the inhabitants of many of the world's major cities and towns, estuaries provide their nearest glimpse of a natural habitat; a habitat which, despite the attempts of man to pollute it or reclaim it, has remained a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. The biologist has become interested in estuaries as areas in which to study the responses of animals and plants to severe environmental gradients. Gradients of salinity for example, and the problems of living in turbid water or a muddy substrate, prevent most animal species from the adjacent sea or rivers from entering estuaries. In spite of these problems, life in estuaries can be very abundant because estuarine mud is a rich food supply which can support a large number of animals with a large total weight and a high annual production. Indeed estuaries have been claimed to be among the most productive natural habitats in the world. When the first edition of this book appeared, biologists were beginning to realise that the estuarine ecosystem was an ideal habitat in which to observe the processes controlling biological productivity.

Estuarine and coastal waters are acknowledged points of anthropogenic impact. For practitioners, academics and students in the field of coastal science and policy, this book examines and exemplifies current and future challenges: from upper estuaries to open coasts and adjacent seas; from tropical to temperate latitudes; from Europe to Australia.

Risk assessment is the cornerstone of contemporary environmental protection. You must find the answers to questions such as: what might be the impacts of the new synthetic chemicals, what problems might arise from the normal operations of industry, what are the chances of accidental releases and how will they impact the environment? Understanding and assessing these risks is essential to sound environmental policy and management. The first book to address the application of the current National Research Council (NRC) risk assessment paradigm to the coastal marine environment, Coastal and Estuarine Risk Assessment covers topics that range from pollutants of emerging concern to bioavailability and bioaccumulation at the suborganismal through landscape levels. It explores the necessary applications for modifying the NRC paradigm and presents a series of steps to actually accomplish an effective assessment using the modified paradigm. The book highlights the logical framework for assessing causation, and measurement of toxicant fate and effect. The chapter authors bring together experiences from academia, private consultants, and government agencies, resulting in a rich mixture of experience and insights. Exploring the science of exposure, effect, and risk in coastal and estuarine environments, Coastal and Estuarine Risk Assessment gives you a building block approach to the fundamental components of risk assessment.
