Cracked-Dry-Land-Soil-DroughtThe Western United States is not the only region of the world that is currently suffering under chronic drought conditions. The largest country in South America — Brazil — is also experiencing drought, and its biggest city is two months away from running out of water entirely. As reported by Reuters, the Brazilian mega-city of Sao Paulo, where 20 million people reside, has about one month’s worth of a guaranteed water supply, as city officials have begun tapping into the second of three emergency reserves.  Reuters further noted: The city began using its second so-called “technical reserve” 10 days ago to prevent a water crisis after reservoirs reached critically low levels last month. This is the first time the state has resorted to using the reserves, experts say.  “If we take into account the same pattern of water extraction and rainfall that we’ve seen so far this month – and it’s been raining less than half of the average — we can say the (reserve) will last up to 60 days,” Marussia Whately, a water resources specialist at the environmental NGO Instituto Socioambiental, told the newswire service over a month ago. The expert went on to say, however, that, with the approaching Christmas and New Year’s holidays, water usage is actually expected to increase, meaning the existing reserves will likely be depleted sooner. After that, said Whately, there is no guarantee or certainty regarding the availability of water to the country’s financial center and wealthiest city. If rainfall does not replenish the Cantareira system, which is the main collection of reservoirs that provide water to Sao Paulo, she said the city could actually run out of water altogether. There is a third, and final, technical reserve, and it could be used, says Vicente Andreu, president of ANA, the country’s water regulatory agency, but it is difficult to get to, and the water is mixed with silt that would likely gum up the pumping process.
