Although the definition of a drought varies from location to location, a
simple definition of the hazard is a prolonged period of dry weather
due to a deficiency in precipitation. Drought is further defined as
meteorological, agricultural, hydrological, and socioeconomic.
Meteorological drought refers to a period of dry weather associated
with lack of precipitation, agricultural drought refers to crop damage
as a result of drought, hydrological drought refers to a drop in
surface and groundwater levels as a result of drought, and socioeconomic
drought refers to impacts on humans individually or collectively.
