Laurentino Meurer, a migrant from southern Brazil, arrived in Jaciparaná about four years ago. He was sure he had made the right choice when he read in a magazine that the dirt-track settlement alongside a river of the same name would be “the fastest-growing place in Brazil”. He hopes that the Drogaria Bom Jesus, the chemist’s shop he runs on the main road, will play a prominent role in the coming boom. Along with remedies, it sells plots of land – 77 a month, he boasts. But that was a while ago. “There is not much demand right now,” he admits.

Mr Meurer’s hopes rest on a government-backed scheme to dam the Madeira River, the Amazon’s mightiest tributary. If this goes ahead, Jaciparaná will host thousands of workers building one of the two dams. Together, the dams would generate 6,450MW of electricity, 8% of Brazil’s installed capacity. If it does not, the district will probably return to the torpor that set in when the rubber-bearing Madeira-Mamoré railway ceased running in 1972, leaving a picturesque ruin of a station.

To hear the prospective builders tell it, the stakes for Brazil are similar. An electricity shortage choked the economy in 2001. Another looms by 2011 unless the Rio Madeira project is approved, says Irineu Meireles of Odebrecht, a construction company that hopes to be majority partner in the scheme.
