Abstract: Drought is one of the most complex climate hazards, affecting several natural systems and socioeconomic sectors (Wilhite, 2000).This makes that although several studies have focused on droughts conceptual issues (Wilhite and Glantz, 1985), it is really impractical to establish an unique definition of this phenomenon (Lloyd-Hughes, 2014).Drought is usually detected when an impact is recorded.It may refer to damages in agriculture (crop yield reductions), ecological impacts (tree decay and/or mortality), but it may also be related to a hydrological dimension, associated to reductions in streamflow, reservoir storages or groundwater decreases (Van Loon, 2015).Drought conditions in different systems may coincide or not in space and time, which makes even more complex the drought characterization and analysis.
