On March 14, 2007, unite with communities around the world to celebrate the *10th ANNIVERSARY* of the International Day of Action Against Dams and for Rivers, Water and Life! Ten years ago, the International Day of Action was launched at the First International Meeting of People Affected by Dams in Curitiba, Brazil. Chosen to coincide with Brazil’s Day of Action Against Large Dams, 14 March is a day of protest and affirmation that has spread from those original 20 countries including Brazil, France, Argentina, the USA, Russia and Lesotho, to over 50 countries and hundreds of local groups. This year we join together, stronger than ever, to protest destructive river development and celebrate successes over the last year. This is also a time to fight for social justice and the rights of communities to have a say in decisions affecting their lives and livelihoods.
