Africa/Global: Damming the world's rivers

The extent to which dams affect the world's large river systems is the focus of a major new study by a research team from the Landscape Ecology Group at Umeå University, Sweden. The rivers studied drain 54% of the world's land area and carry 60% of the planet's river-water. The researchers found that of 292 large river systems, 172 are affected by dams. An article in the latest edition of World Rivers Review, published by the International Rivers Network, interviewed the researchers involved.
