Drought 15
Drought 15 : In terms of a natural disaster, drought is rarely properly defined as "a lack or shortage of rainfall". Rather, economic and social factors influence the degree of susceptibility of the affected people, as does the physical situation of the affected area. Crop failure as a result of soil water stress and the associated economic difficulty is a key factor in defining a drought-stricken area, but this is only one category of drought definition (agricultural drought). Others include meteorological drought (which points to physical and natural atmospheric factors and their variability) and hydrological drought (a drought pertaining to a lack of 'terrestrial water' such as a reduction in stream flow and water levels in dams and lakes).
