                         drought ever recorded in the semiarid region Northeast Brazil. 
                         Droughts are recurrent in the region and while El Nino has driven 
                         some of these events others are more dependent on the tropical 
                         North Atlantic sea surface temperature fields. The drought 
                         affecting this region during the last 5 years shows an intensity 
                         and impact not seen in several decades in the regional economy and 
                         society. The analysis of this event using drought indicators as 
                         well as meteorological fields shows that since the middle 1990s to 
                         2016, 16 out of 25 years experienced rainfall below normal. This 
                         suggests that the recent drought may have in fact started in the 
                         middle-late 1990s, with the intense droughts of 1993 and 1998, and 
                         then the sequence of dry years (interrupted by relatively wet 
                         years in 2007, 2008, 2009 and 2011) after that may have affected 
                         the levels of reservoirs in the region, leading to a real water 
                         crisis that was magnified by the negative rainfall anomalies since 
                         2010.",
