Drought is one of the natural climatic extreme events that may cause significant damage to environments and claim human lives. Drought greatly affects many aspects of environment and society, and any future increases in the demand for water will be most critical in periods of severe drought. Analysis of drought events and their causes can be used to mitigate the drought impacts and development of preparedness plans The main purpose of this study is to investigate the drought persistence and severity in the Tripura state of India during the period 1980-2013, using Standardized Precipitation Index (SPI). Gridded monthly precipitation data distributed over the four districts of Tripura was used. SPI series of 3, 6 and 12 month time scales have been calculated and used for drought analysis. Several drought events were detected during the rainy season (June to September). Annual analysis of SPI time series showed that the study area received the intense drought during the year 1985. Geospatial technique was used to generate the SPI drought map for the year 1985.
