Abstract

In this study drought monitoring and assessment have been studied over Jharkhand state of India. Now a days, climate uncertainty is one of the major problem due to climate change and anthropogenic activities over the globe. The identification of the problem is the key element for mitigate the above mentioned issues using historical data sets. For the purpose three different indices have been utilized i.e., Standard Precipitation Index (SPI), Normalized Vegetation Index (NDVI) and Vegetation Condition Index (VCI). Hence, Python based programme and Remote Sensing and GIS based techniques have been used to quantify the SPI, NDVI and VCI respectively. The study highlights the drought characteristics such as intensity, onset and offset of drought using SPI at 3, 6 and 12 months’ time scales during 1951 to 2002 for 18 districts in Jharkhand. MODIS satellite imageries have been utilised during 2000 to 2018 (October month) to derive the VCI and NDVI maps. The SPI analysis reveals that year 1966 found to be the water deficit year followed by 1992 from the span of 1951 to 2002 in Jharkhand. From the analysis it was also found that, about 78% and 56% stations experienced with extreme drought condition in year 1966 and 1992 respectively. It was also observed that as the time scale increases, the duration of drought also increases whereas, the intensity and frequency are decreases. The present study highlights spatial and temporal variations of drought severity at different location at different scales. The study can be helpful for priority based remedial solution and legislative decision making process over the state against the drought issues.
