Power in the jungle

The Economist (adapted)

1st June 2006

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.

Infrastructure in Latin America

It is impossible to see such a thing and disbelieve in progress. Where there was air, there is rock. Where there was rock, there is air. Where there was no lake, there will be a lake. El Cajón, a dam 188 metres (617 feet) tall in Nayarit, in western Mexico, is to generate 750MW of
electricity starting in 2007.

El Cajón is Latin America’s biggest construction project. It is also a rarity. In Mexico, public spending on infrastructure – electricity generation, roads, railways, water plants and the like – was a third lower in 2004 than a decade earlier, according to a report by Merrill Lynch, an investment bank. The World Bank describes two-fifths of the country’s motorways as “pre-modern”. Nevertheless, the government has found the money to spend 0.7% of GDP on subsidizing the electricity that is consumed – which does nothing for the poorest, who live in the dark in rural areas.

So it is across Latin America. Although the region’s economies are growing faster, thanks to an export boom, they are hobbled by poor roads and railways, clogged ports and a precarious electricity supply. In the 1990s governments slashed public investment to balance their budgets and invited private investors to make up for the shortfall.

In the 1990’s, governments slashed public investment, which means they

Sabe-se que, no mesmo mês de junho, Luís vendeu 6 imóveis. Com essas informações, conclui-se que, no mês de junho, o número de imóveis que a imobiliária vendeu foi igual a:
