TI - Development of index to assess drought conditions using geospatial data a case study of Jaisalmer District, Rajasthan, India
AB - The Jaisalmer district of Rajasthan province of India was known to suffer with frequent drought due to poor and delayed monsoon, abnormally high summer-temperature and insuffi cient water resources. However fl ood-like situation prevails in the drought prone Jaisalmer district of Rajasthan as torrential rains are seen to affect the  region in the recent years. In the present study, detailed analysis of meteorological, hydrological and satellite data of the Jaisalmer district has been carried out for the years 2006−2008. Standardized Precipitation Index (SPI), Consecutive Dry Days (CDD) and Effective Drought Index (EDI) have been used to quantify the  precipitation defi cit. Standardized Water-Level Index (SWI) has been developed to assess ground-water recharge-defi cit. Vegetative drought indices like Vegetation Condition Index (VCI), Temperature Condition Index (TCI), Vegetation Health Index (VHI), Normalized Difference Vegetation Index (NDVI) and Modifi ed Soil-Adjusted Vegetation Index 2 have been calculated. We also introduce two new indices Soil based Vegetation Condition Index (SVCI) and Composite Drought Index (CDI) specifi cally for regions like Jaisalmer where aridity in soil and affects vegetation and water-level.
