São Paulo could face more devastating water shortages if farmers continue to clear the Amazon forest, warns the utility chief who recently steered the biggest city in the Americas from the edge of drought catastrophe.
Jerson Kelman, president of water company Sabesp, told Guardian Cities he felt a duty to speak out because he was a citizen as well as the head of a company who had seen firsthand how close this metropolis of 21 million people had come to a breakdown.
We should not transform the Amazon into pastureland, he said in an interview. The Amazon creates a movement of water. If you could follow a molecule of water you would see that most of the clouds that are over São Paulo have passed across the Amazon. If the forest is cut, well be in trouble.
As one of the foremost authorities on water supply and hydropower in Brazil, Kelmans comments are likely to reignite a debate resisted by the countrys powerful agriculture lobby about the link between the worlds biggest forest, climate change and a possible recurrence of the 2014-15 drought.
