             abstract = "This study provides an overview of the drought situation in 
                         Northeast Brazil for the past, present, and future. Droughts 
                         affect more people than any other natural hazard owing to their 
                         large scale and long-lasting nature. They are recurrent in the 
                         region and while some measures have been taken by the governments 
                         to mitigate their impacts, there is still a perception that 
                         residents, mainly in rural areas, are not yet adapted to these 
                         hazards. The drought affecting the Northeast from 2012 to 2015, 
                         however, has had an intensity and impact not seen in several 
                         decades and has already destroyed large swaths of cropland, 
                         affecting hundreds of cities and towns across the region, and 
                         leaving ranchers struggling to feed and water cattle. Future 
                         climate projections for the area show large temperature increases 
                         and rainfall reductions, which, together with a tendency for 
                         longer periods with consecutive dry days, suggest the occurrence 
                         of more frequent/intense dry spells and droughts and a tendency 
                         toward aridification in the region. All these conditions lead to 
                         an increase in evaporation from reservoirs and lakes, affecting 
                         irrigation and agriculture as well as key water uses including 
                         hydropower and industry, and thus, the welfare of the residents. 
                         Integrating drought monitoring and seasonal forecasting provides 
                         efficient means of assessing impacts of climate variability and 
                         change, identifying vulnerabilities, and allowing for better 
                         adaptation measures not only for medium- and long-term climate 
                         change but also for extremes of the interannual climate 
                         variability, particularly droughts.",
