"Concrete Revolution "offers a compelling historical account of the U. S. Bureau of Reclamation's contributions to dam technology, Cold War politics, and the social and environmental adversity perpetuated by the U.S. government in its pursuit of capitalist economic development. Founded in 1902, the Bureau amassed geopolitical power after the Second World War, in response to the Soviet Union's increasing global influence. By offering technical and water resource management advice to the world's underdeveloped regions, the Bureau found that it could not only provide them with economic assistance, and provide the U.S. with investment opportunities, but also gain alliances for the U.S. and further the country's global standing in the face of a burgeoning communist regime. The book includes a number of case studies, from the Bureau's foray into overseas development and the launch of its Foreign Activities Office in 1950, to specific projects such as the Litani River initiative in Lebanon, the Blue Nile investigation in Ethiopia, and the Mekong river basin development project in mainland Southeast Asia, the bureau's longest international undertaking, which affected Thailand, Laos, Cambodia, and Vietnam. If, Sneddon argues, we can come to understand dams as both technical and political objects rather than mere instruments of impartial science, we can better participate in current debates about large dams and river basin planning.
