Over 1 million barriers on Europe’s rivers World December 17, 2020 More than 1.2 million barriers criss-cross Europe’s rivers -- nearly twice as many as previously thought -- threatening some of the world’s most diverse ecosystems, new research showed Wednesday. Although the rivers have been dammed, forded or bridged for centuries, there is a surprising lack of detailed databases of the continent’s waterways.
