Close to 1 billion people lack access to fresh water, according to the second triennial World Water Development Report from the United Nations. The report, presented this week at the World Water Forum in Mexico City, is a panoramic view of world water problems. It includes photographs such as this one above of nomad women drawing water in Mauritania; case studies, such as water-management plans for the Danube watershed and for the greater Tokyo area; and illuminating charts, including one showing how U.S. sales of agricultural products to Japan make Japan a huge importer of "virtual water."
