The Amazon — the lush, tropical basin that holds the world’s biggest river, rainforest and a fifth of its fresh water — is running dry.

The region is entering its fifth month of a drought that has been particularly punishing in the northern reaches of the rainforest, in the region around the city of Manaus. The Rio Negro, a northern Amazon tributary, fell to the lowest levels in its recorded history last month. Wildfires have advanced where waterways have retreated.

The Amazon River fell to its lowest level in over a century on Monday at the heart of the Brazilian rainforest as a record drought upends the lives of hundreds of thousands of people and damages the jungle ecosystem.

Rapidly drying tributaries to the mighty Amazon have left boats stranded, cutting off food and water supplies to remote villages, while high water temperatures are suspected of killing more than 100 endangered river dolphins.

Brazil announces end to Amazon mega-dam building policy

  • Brazil’s government this week announced a major shift away from its policy of building mega-dams in the Brazilian Amazon – a strategy born during the country’s military dictatorship (1964-1985) and vigorously carried forward down to the present day.
  • The Temer government claims the decision is a response to intense resistance from environmentalists and indigenous groups, but while that may be part of the reason, experts see other causes as well.
  • The decline in political influence of Brazil’s gigantic construction companies caused by the Lava Jato (Car Wash) corruption investigation is likely a major cause of the change in policy. So is the current depressed state of Brazil’s economy, which makes it unlikely that Brazil’s huge development bank (BNDES) will invest in such multi-billion dollar projects.
  • While environmentalists and indigenous groups will likely celebrate the shift away from the mega-dam policy, experts warn that many threats to the Amazon remain, including pressure by Brazil’s ruralist lobby to open up conserved areas and indigenous lands to agribusiness, along with threats posed by new road, rail, waterway and mining projects.
