Amazon levels at 30-year low
The authorities on the Brazilian stretch of the Amazon are taking emergency action to deal with one of the worst droughts in decades. Scientists say water levels in the river have fallen to a thirty-year low. This report from Simon Watts:
The Amazon is a lifeline for everyone in the river basin, from businessmen in the big city of Manaus to indigenous tribes in remote settlements.
When water levels fall, the biggest effect is on transport - ferries and barges are the only real way of moving goods and people around an area that spans about half the South American continent. In the last few weeks, the river and its tributaries have become increasingly difficult to navigate, and vital supplies of food, medicine and fuel are now struggling to get through. In an example of the risks, sixteen people were killed last Friday in a ferry accident which the captain blamed on difficult river conditions.
The dry weather in the Amazon has also caused huge fires in jungle areas. One recent blaze covered northern Bolivia in smoke, as well as the neighbouring part of Brazil. As to the cause of this low rainfall, scientists say it's probably cycles in the climate, not global warming. They think the weather in the Amazon is affected by sunspots and water temperatures in the Pacific - factors which vary in regular patterns. The bad news is that this dry cycle is expected to continue for another month.
