Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.

Eutrophication is a problem which became widely recognised by the scientific community in the 1940s and 1950s. It raised public concern, resulting in increased research effort and expenditure on management techniques through the 1960s and 1970s, recognised as a distinct problem of water pollution, though linked with the more gross effects of organic pollution. In the 1980s it became less fashionable - replaced in the public's eye and the politician's purse by newer problems such as acid rain. It remains however, one of the biggest and most widespread problems of fresh waters, particularly of lakes and an increasing problem for estuaries and coastal waters. It is one with which almost all water scientists and engineers in urbanised areas of the world have to cope. Technical methods for the reversal of eutrophication, such as nutrient removal, have been developed and applied successfully in some instances. They are not widespread however, and where they are feasible, they are often expensive and may be politically difficult to implement. In the last decade, attention has focussed upon less expensive lake manipula tion techniques, such as destratification and biomanipulation, which aim to minimise rather than elimininate the detrimental effects of eutrophication. These are becoming more widely applied. Prediction of the potential problems in lakes and catchments which have not yet suffered the full effects of eutrophication is now accurate enough to be of direct benefit to river basin management.

Eutrophication continues to be a major global challenge and the problem of eutrophication and availability of freshwater for human consumption is an essential ecological issue. The global demand for water resources due to increasing population, economic developments, and emerging energy development schemes has created new environmental challenges for global sustainability. Accordingly, the area of research on eutrophication has expanded considerably in recent years. Eutrophication, acidification and contamination by toxic substances are likely to pose increasing threats to freshwater resources and ecosystems. The consequences of anthropogenic-induced eutrophication of freshwaters are severe deterioration of surface waters and growing public concern, as well as new interest among the scientific community. “Eutrophication: causes, consequences & control” provides the latest information on many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. This book offers a cutting-edge resource for researchers and students alike who are studying eutrophication in various ecosystems. It presents the latest trends and developments in the field, including: global scenarios and local threats to the dynamics of aquatic ecosystems, economics of eutrophication, eutrophication in the great lakes of the Chinese pacific drainage basin, photoautotrophic productivity in eutrophic ecosystems, eutrophication’s impacts on natural metal remediation in salt marshes, phytoplankton assemblages as an indicator of water quality in seven temperate estuarine lakes in southeast Australia, biogeochemical indicators of nutrient enrichments in wetlands – the microbial response as a sensitive indicator of wetland eutrophication, and ultraviolet radiation and bromide as limiting factors in eutrophication processes in semi-arid climate zones. Written by respected experts and featuring helpful illustrations and photographs, “Eutrophication: causes, consequences & control” provides a concise and practical update on the latest developments in eutrophication.

Nutrient enrichment (eutrophication) is a major theme in freshwater ecology. Some themes come and go, but the inevitable release of phosphorus and nitrogen that ac companies human presence seems to ensure that eutrophication will not soon become an outmoded subject of study. Eutrophication raises issues that range from the pressingly practical problems of phosphorus removal to the very fundamental ecological questions surrounding biological community regulation by resource supply. Although it is possible to take a reductionist approach to some aspects of eutrophication, the study of eutro phication is fundamentally a branch of ecosystem ecology. To understand eutrophication in a given setting, one is inevitably forced to consider physical, chemical, and biological phenomena together. Thus while eutrophication is the focus of our study of Lake Dillon, we have assumed that a broad base of lirnnological information is a prerequisite foundation. Eutrophication of a lake can be studied strictly from a lirnnological perspective. If so, the nutrient income of the lake is quantified but the sources are combined within a black box whose only important feature is total loading. It is also possible, however, to treat the watershed and lake as equally important components of a hybrid system. In this case the nutrient sources must be dissected and their variability and dependence on key factors such as runoff must be quantified.

This volume focuses on the nutrient and organic matter inputs in estuaries and other coastal ecosystems, their effects on geochemistry and community structure and possibilities for recovery of the systems to a trophic state that is beneficial for man and nature. The book provides many examples of the effects of the enhanced supply of nutrients and organic matter on the chemical features of the water and on the structure, metabolism and trophic pathways of the biological communities. Also included are several case studies providing considerable insight into the response of the different coastal ecosystems to long term changes in the trophic state of the water. Current knowledge on modeling as a tool to manage the trophic state of the coastal ecosystems is also dealt with, making this book one of interests to scientist and students as well as managers.

A comprehensive introduction to eutrophication, the process by which the water quality of lakes deteriorates as a result of their increased levels of nutrients. (These nutrients, however, also increase the fertility of lakes.) The process normally takes centuries, but is accelerating as a result of man's activities in catchment areas. The book is divided into three parts. The first part looks at basic causes and control strategies; the second considers conflict between the natural environment and man's influence; the third presents the scientific basis of our understanding of both eutrophication and its control.
