Download or read book Aquatic Habitats in Sustainable Urban Water Management written by Iwona Wagner and published by CRC Press. This book was released on 2008-01-07 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic habitats supply a wide range of vital ecosystem benefits to cities and their inhabitants. The unsustainable use of aquatic habitats, including inadequate urban water management itself, however, tends to alter and reduce their biodiversity and therewith diminish their ability to provide clean water, protect us from waterborne diseases and pollutants, keep urban areas safe from flooding, and support recreational ecosystem services and even the aesthetic enjoyment of our world. Aquatic Habitats in Sustainable Urban Water Management – the result of collaboration between UNESCO’s International Hydrological Programme and its Man and the Biosphere Programme – aims at improving our understanding of aquatic habitats, related ecosystem goods and services, and conservation and sustainable use – with a special focus on their integration into urban water management. The first part of this volume reviews basic concepts and challenges in urban aquatic habitats, as well as strategies for their management integration. The second part examines technical measures related to habitats management and rehabilitation, along with their incorporation into urban planning and their role in human health. The final part looks at current urban aquatic habitat issues and practical approaches to solving them through the lens of case studies from around the globe. Urban Water Series - UNESCO-IHP Following from the Sixth Phase of UNESCO’s International Hydrological Programme (2002–2007), the Urban Water Series – UNESCO-IHP addresses fundamental issues related to the role of water in cities and the effects of urbanization on the hydrological cycle and water resources. Focusing on the development of integrated approaches to sustainable urban water management, the Series should inform the work of urban water management practitioners, policy-makers and educators throughout the world.

Book excerpt: There is a pressing need for developing and testing a general set of theories in order to provide a confident basis for prediction of multiple stressor effects. Confident prediction is central to confident decision making in water pollution control. Consequently, WERF commissioned this study which has as its goal to provide a study design based on good science that helps establish a general, conceptual approach to multiple stressors. The objectives of the study are to develop a flexible and scientifically defensible conceptual model of the environmental effects of multiple stressors on river and stream ecosystems; develop a study design to test the conceptual model of multiple stressor effects; and, document the process used to arrive at the conceptual model. The multiple stressor conceptual model includes two main components: (1) a diagram that portrays the main features of the study team's understanding of how multiple stressors would interact and the nature of the effects; and (2) a series of three testable risk hypotheses. These two components follow the guidance provided by the U.S. EPA for ecological risk assessment. The proposed conceptual model encompasses the following key assumptions: interactions between the stressor and the ecosystem are dependant upon the existing baseline conditions; for each stressor/baseline combination there will theoretically be a functional and a structural response; effects on habitat are caused by structural or functional responses to stressors; and effects on habitat can cause structural or functional responses.

Download or read book Alternatives in Regulated River Management written by James A. Gore and published by CRC Press. This book was released on 2018-01-18 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.
Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

This book was released on 2018-01-18 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of freshwater fisheries changing their strategies from the regulation of harvest and the enhancement of populations, to the creation and protection of habitats and the management of ecosystems, moves toward establishing an aquatic habitat classification system. Eight papers, from the February 1988 Symposium on the Classification and Inventory of Great Lakes Aquatic Habitats (the last in a series of Great Lakes Symposia), propose various classification approaches, most using a limited number of physical, chemical, and/or biological variables to produce some form of index. They also include overviews and summaries of the classification process.
