Southern Africa is, by and large, a dry place. Water is perhaps the region's most precious resource - the source of life itself. And yet the region's life-giving source of water - rivers and their catchments - are increasingly under threat from ill-conceived development schemes. International Rivers Network is devoted to protecting rivers on an international scale, from the Amazon to the Zambezi. Through research, activism and outreach, IRN takes on powerful governments and industries that bulldoze their way through communities with destructive river development projects.
