Drought is a slow onset phenomenon that affects people’s socio-economic activities to a great extent. It is one of the most
dangerous natural hazards because it is very difficult to identify its onset. In India, Gujarat is one of the states which face the drought
generally once in three years. Therefore, monitoring of drought by various drought indices has a great potential in mitigation the future
droughts. In this paper the Standard Precipitation Index (SPI) has been used to monitor drought in Rajkot district, Gujarat, India. The
Standard Precipitation Index has been calculated for 3-month, and 6-month time scales to decide the effect of water scarcity on the
various natural resources. The SPI value will give information about drought characteristics i.e. severity, frequency and spatial extent
for Rajkot district. The monthly rainfall data of 5 rainfall stations named Morbi, Rajkot, Lodhika, Jasdan, Gondal, has been collected
for the period of 1981-2010 to calculate the Standard Precipitation Index (SPI). The results suggest that the Rajkot region had felt
severe drought in 1987 A.D. On an average there is a condition of drought in Rajkot district once in two years. It can be also concluded
that since 2005 Rajkot district has not felt any major drought.
