Book excerpt: This document, produced by Working Group 2.3 REFCOND, aims at guiding experts and stakeholders in the implementation of Directive 2000/60/EC establishing a framework for Community action in the field of water policy (the water framework directive). It focuses on the implementation of the Annexes II and V with special emphasis on inland surface waters and methods and principles for the establishment of reference conditions and class boundaries between high, good and moderate ecological status. The guidance will be useful for: establishing reference conditions and ecological status class boundaries for inland surface waters, and participating in the process as a stakeholder; leading and managing experts undertaking the ecological status analysis; using the results of the ecological status analysis for taking part to the policy making process; or reporting on the ecological status analysis to the European Union as required by the directive.
Download or read book The Chironomidae written by P.D. Armitage and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.
Download or read book Large Lakes written by Max M. Tilzer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.

Book excerpt: River Basin Management is a collection of papers presented at a conference on implementation of the EU Water Framework Directive, held in Budapest in May 2005. The Water Framework Directive requires progressive protection and enhancement to rivers, lakes, estuaries, coastal waters and wetlands by the year 2015. At the heart of this major new piece of legislation is the requirement for all EU member states to prepare river basin management plans for all river basin catchments, providing the basis for coordinated improvements to water management, leading to better water quality and sustainable aquatic environments in lakes and rivers. The papers cover a wide range of topics including pilot studies for the development of river basin management plans, public participation in the planning process, water quality monitoring, modeling and analysis, identifying and addressing pollution and meeting environmental objectives. The book presents an array of experience from eighteen European countries in the implementation of the EU’s most far reaching environmental legislation. It is an invaluable source of information and ideas for the widespread preparation of river basin management plans now starting throughout Europe.
