Further development of Water Framework Directive necessary
Date:11/30/2007

n of renewable energy sources aims to increase use of water power by 10 to 20 per cent. Studies from Scandinavia, where people have been generating electricity from water power for a hundred years, have shown that this type of power generation has major consequences for the ecological status of rivers. Shallow areas are particularly affected because the water level fluctuates considerably over the course of the year. Among other things, this severely restricts the growth of aquatic plants in these areas, which are then not available for fish for spawning or for foraging. In many cases then, the issue of a rivers ecological status is interesting not only from the point of view of environmental protection the many and varied goods and services that healthy ecosystems supply to humans, such as the provision of food and drinking water and maintaining nutrient cycles, are also of major economic importance.
