 in Brazil. The project, which was given the green light to go ahead by Brazil's government in 2005, is estimated to cost US$2 billion and is expected to improve the lives of 12m people. After legal challenges were brought against the project, the Supreme Court allowed it to go ahead in December 2007.

The project would divert 1.4% of the river's water for municipal water supply, industry and irrigation. Municipal water supply would receive priority over other uses, which would only be catered for only when the reservoir behind the Sobradinho

 also wonders why water is being exported when 3m poor live along the Sao Francisco river's course, many of them without running water and proper sanitation. He argues that the transfer “will demand huge resources that could be spent on other projects much closer to the reality of the people”. It is also being said that the project will mainly benefit richer farmers who already have irrigation infrastructure in place and not rainfed farmers that are hardest hit by drought. The alleged insufficiency of water in the Sao Francisco River itself during the dry season, and its consequent impact on aquatic ecosystems, is another argument of critics. For example, João Alves Filho, governor of the state of Sergipe

Marco Antônio Tavares Coelho, a prominent opponent, says that "aridity is the natural state of the sertão" and that soaking it would be like "removing ice from the North Pole". In 2001 the World Bank reportedly refused to finance the project because of its limited impact in combating poverty and drought.
