Global: Free-flowing rivers - economic luxury or ecological necessity?

This report assesses the state of the world’s remaining free-flowing rivers and seeks to answer the question why we should maintain our last free-flowing rivers. Most of the world’s largest rivers are losing their connection to the sea, and only a third of the world’s 177 large rivers remain free-flowing, unimpeded by dams or other barriers. A concerted effort for their conservation is urgently needed.
