The 2015 Brazilian drought is an ongoing drought affecting the southeast of Brazil including the metropolitan areas of São Paulo and Rio de Janeiro. It has been described as the worst drought in 80 years. The city of São Paulo appears to be affected the most and by the beginning of February many of its residents were subject to sporadic water cutoffs. ==Extent== Typically the rainy season starts in November, but lack of rain in the 2014/15 season led to a major shortfall in the water supply in the states of São Paulo, Rio de Janeiro, and Minas Gerais.〔 With major reservoirs operating at their lowest capacity (the main reservoir system of Cantareira supplying São Paulo being at only 6% of its capacity in early February〔) officials at São Paulo warned about extended rationing as water may run out before the next rainy season in November 2015.〔 In response, the water utility of Sao Paulo, Sabesp, has reduced water pressure in the system. It also started to impose punitive tariffs on users who use more than in previous years. By early February residents had started to recycle and hoard water.〔 By the end of February torrential downpours caused flooding in Sao Paulo, but the rain was not thought to be enough to result in significant replenishment of the water reservoirs. At the beginning of the dry season, by early May 2015, the water crisis continues and water reservoirs in the Sao Paulo area are insufficiently filled. Work is underway to link up various reservoirs to make better use of existing water resources.〔 By October 2015 the Cantareira reservoirs contained 12% of their capacity while the polluted Billings Reservoir had 20%. There is concern that the unresolved water crisis may impact the 2016 Olympic Games.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2015 Brazilian drought」の詳細全文を読む スポンサード リンク
