The agricultural drought has become a major concern worldwide because of its severe effect on the productivity of rain-fed crops and direct effect on service as well as per capita income. These agricultural droughts occur due to short-term moisture stresses. This work was carried out to analyze droughts in the Banswara region of Rajasthan using Effective Drought Index (EDI). Out of the 11 rain gauge station selected in the study, it was found that according to EDI, a meteorological drought of maximum severity -34.15 occurred for the duration of September 1989 to June 1991 which was of the longest period (22 months) in the study area falling under Sajjangarh rain gauge station. The drought having a maximum intensity of -2.13, occurred in between July 1979 to May 1980, with a severity of -23.46 in the area under Bhungra rain gauge station. The maximum and a minimum number of extreme drought which occurred in Loharia and Arthuna rain gauge station were respectively 10 and 2. A maximum number of 19 severe droughts and 59 moderate droughts occurred in Kushalgarh and Bagidora area respectively and a minimum number of one severe drought and 28 moderate droughts occurred in Banswara and Loharua rain gauge stations respectively. The maximum and a minimum number of 65 and 42 drought events occurred in Kushalgarh and Shergarh rain gauge station respectively. The rising trend of meteorological drought severity was found in the study area.
