Book Description
As part of a larger project on development of an ecosystem integrity and cumulative effects monitoring program for the Peace, Athabasca, and Slave River basins, this report reviews the concept of ecosystem health and cumulative effects assessment as well as the theoretical framework and practical objectives of these approaches. The report reviews the literature on existing individual, population-, and community-level approaches and associated measurements being used for the assessment of aquatic ecosystem health and cumulative effects. It also identifies the types of data required to assess and monitor aquatic ecosystem health and cumulative effects in large northern rivers. Finally, the report discusses the applicability of these approaches and associated measurements, and recommends approaches with potential for use in the Northern River Basins Study.

Book Description
With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.

Book Description
Ecosystem health offers a fresh perspective on the management of natural resources and the environment. While some of the root concepts can surely be traced back to Aldo Leopold and even earlier, it is only in the recent decade that a substantial body of work has emerged on this topic. There is no question that a novel approach which is by its nature cross disciplinary, bridging the health and biological sciences, will initially raise a number of questions particularly pertaining to the use of metaphors and the validity of the analogy. This volume however goes beyond merely the philosophical dimensions of the subject by covering a number of case studies which have given rise to the development of promising quantitative methods for diagnosis and rehabilitation of ecosystems under stress. The focus of most studies is on regional ecosystems i.e. ecosystems of large scale. As such, the methods and approaches should have wide appeal to government agencies charged with the responsibility of sustainable development of regional ecosystems and natural resources. Health is one of those difficult concepts that everyone thinks they can define, until they come to try. We all have personal knowledge about health and illness and this makes the ecosystem analogy so potentially powerful. Yet it is also clear that the uncritical application of the concept could lead to overly simplistic approaches to analysis and management of ecosystem health.

Book Description
Water quality for ecosystem and human health is the first report of its kind produced by UNEP's GEMS/Water Programme. Drawing on examples from around the world, the report presents assessments of current status and trends in water quality. It also provides an introduction to a diverse range of issues of concern in global water quality, and approaches to their detection, analysis, and resolution. It is difficult to obtain a global picture of water quality as different countries and regions struggle with a range of environmental pressures and the reality of limited resources available for monitoring, assessment and remediation. However, the report highlights five key messages: (1) Human-driven processes often have the greatest negative impact on the quality of water resources, even in remote environments; (2) Impaired aquatic ecosystems can lead to impaired human health and socio-economic decline; (3) There are new threats to the health of aquatic ecosystems for example, pharmaceuticals and personal care products, requiring immediate attention by regulatory authorities at local, national and global levels; (4) Successful procedures have been developed for the restoration of aquatic ecosystems including damage caused by acidification and eutrophication, and (5) Baseline monitoring data for aquatic ecosystems is a priority. Long-term monitoring is also required to track the effectiveness of policies and interventions.
