Ecosystem services are emerging as a key driver of conservation policy and environmental management. Delivery of ecosystem services depends on the efficient functioning of ecosystems, which in turn depends on biodiversity and environmental conditions. Many marine ecosystems are extremely productive and highly valued, but they are increasingly threatened by human activities. With contributions from leading researchers, this volume synthesises current understanding of the effects on biodiversity and ecosystem functioning caused by a variety of human activities and pressures at play in coastal marine ecosystems. The authors examine the likely consequences for ecosystem service provision, covering key topics including fisheries, aquaculture, physical structures, nutrients, chemical contaminants, marine debris and invasive species. Critically reviewing the latest developments, this is a unique resource both for environmental managers and policy-makers, and for researchers and students in marine ecology and environmental management.

Dynamic and productive ecosystems, coastal lagoons play an important role in local economies and often bear the brunt of coastal development, agricultural, and urban waste, overuse from fisheries, aquaculture, transportation, energy production, and other human activities. The features that make coastal lagoons vital ecosystems underline the importance of sound management strategies for long-term environmental and resource sustainability. Written by an internationally renowned group of contributors, Coastal Lagoons: Critical Habitats of Environmental Change examines the function and structure of coastal lagoonal ecosystems and the natural and anthropogenic drivers of change that affect them. The contributors examine the susceptibility of coastal lagoons to eutrophication, the indicators of eutrophic conditions, the influences of natural factors such as major storms, droughts and other climate effects, and the resulting biotic and ecosystem impairments that have developed worldwide. They provide detailed descriptions of the physical-chemical and biotic characteristics of diverse coastal lagoonal ecosystems, and address the environmental factors, forcing features, and stressors affecting hydrologic, biogeochemical, and trophic properties of these important water bodies. They also discuss the innovative tools and approaches used for assessing ecological change in the context of anthropogenically- and climatically-mediated factors. The book investigates the biogeochemical and ecological responses to nutrient enrichment and other pollutants in lagoonal estuaries and compares them to those in other estuarine types. With editors among the most noted international scholars in coastal ecology and contributors who are world-class in their fields, the chapters in this volume represent a wide array of studies on natural and anthropogenic drivers of change in coastal lagoons located in different regions of the world. Although a significant number of journal articles on the subject can be found in the literature, this book provides a single-source reference for coastal lagoons within the arena of the global environment.

Wetlands And Human Health

The book addresses the interactions between wetlands and human health and well-being. A key feature is the linking of ecology-health and the targeting of practitioners and researchers. The environmental health problems of the 21st Century cannot be addressed by the traditional tools of ecologists or epidemiologists working in their respective disciplinary silos; this is clear from the emergence and re-emergence of public health and human well-being problems such as cholera pandemics, mosquito borne disease, and episodic events and disasters (e.g. hurricanes). To tackle these problems requires genuine cross-disciplinary collaboration; a key finding of the recently concluded Millennium Ecosystem Assessment when looking at human well-being and ecosystem health. This book brings the disciplines of ecology and health sciences closer to such a synthesis for researchers, teachers and policy makers interested in or needing information to manage wetlands and human health and well-being issues.

Based on the bestselling book, Rivers of North America, this new guide stands as the only primary source of complete and comparative baseline data on the biological and hydrological characteristics of more than 180 of the highest profile rivers in Europe. With numerous full-color photographs and maps, Rivers of Europe includes conservation information on current patterns of river use and the extent to which human society has exploited and impacted them. Rivers of Europe provides the information ecologists and conservation managers need to better assess their management and meet the EU legislative good governance targets. Coverage on more than 180 European rivers Summarizes biological, ecological and biodiversity characteristics Provides conservation managers with information to resolve conflicts between recreational use of rivers, their use as a water supply, and the need to conserve natural habitats Data on river hydrology (maximum , minimum and average flow rates), seasonal variation in water flow Numerous full-color photographs Information on the underlying geology and its affect on river behaviour

Although 'biodiversity' is a relatively new coinage, scientists have been studying the subject it describes long before the word's first appearance in the language in the mid-1980s. In 1973, for instance, the UK Systematics Association held a symposium on 'The Changing Flora and Fauna of Britain' which concluded that not enough attention was being paid to the conservation of rarities, a conclusion also reached, said the symposium, at a meeting of the Linnaean Society some forty years earlier. By 1980, the Global 2000 Report to the President published by the US Council on Environmental Quality starkly warned of a diminution of up to one-fifth of all species by the turn of the century, and there is now a growing consensus that the world faces a 'biodiversity crisis' - a potentially catastrophic global loss of genetic, ecosystem, and, most obviously, species diversity.Indeed, especially since the UN Convention on Biological Diversity was promulgated in Rio de Janeiro in 1992, conserving biodiversity has become the principal focus of the global conservation movement. Indeed, the study of the origins, maintenance, and protection of diversity has become perhaps the most vibrant offshoot of ecology and conservation studies. It is increasingly taught and studied in universities - and other research institutions - around the world. Addressing the need for an authoritative reference work to make sense of this rapidly growing subject, and its ever more complex and multidisciplinary corpus of scholarly literature, Biodiversity and Conservation is a new title in the Routledge series, Critical Concepts in the Environment.Edited by Richard Ladle of Oxford University's Centre for the Environment, this new Major Work brings together in five volumes the foundational and the very best cutting-edge scholarship to provide a synoptic view of all the key issues and current debates

The "Assessment of Assessments" (AoA) is a start-up phase of a regular process for global reporting and assessment of the state of the marine environment including socio-economic aspects. AoA represents the most comprehensive initiative undertaken to date by the UN system to better coordinate ocean governance. Its central recommendation calls for a mechanism that builds on existing global, regional and national institutions and processes while integrating all available information, including socio-economic data, on how our seas and oceans are actually being used.--Publisher's description.

The goal of the report project is to define the habitat requirements of seagrasses in the European coasts, the present threats to the sustainability of the ecosystem they form, and their resilience to disturbance in order to strengthen our forecast capacity and formulate cost-effective monitoring plans and management strategies.
