Abstract: Drought is a natural disaster which is having a negative impact on water resources and crop growth. The objective of the study is to identify the drought prone areas using Composite Drought Index, developed using the major components of drought i.e., Meteorological, Agricultural and Hydrological components which includes the sub components such as Departure Index (DI), Dry Spell, Moisture Adequacy Index (MAI), Normalized Difference Vegetation Index (NDVI) and Ground Water Drought Index (GWDI), in Chamarajanagara District of Karnataka from the year 2009 to 2017. Rainfall pattern (South-West monsoon and North- East Monsoon) has been incorporated in the study. Using variance method, composite indices were developed by computing weights for each Meteorological, Agricultural and Hydrological components. Composite Drought Index (CDI) was developed for each Hobli by integrating all the major components and finally drought vulnerability classifications were generated and drought prone areas were identified. Geographical Information System (GIS) is an effective tool to represent and draw the results. The resultant drought maps will help in development of mitigation measures. The drought risk maps were generated which shows that parts of Santemarahalli hobli, Harve hobli and Begur hobli are slightly vulnerable to drought and all the others parts of the district are moderately vulnerable to drought. This study will help in future to adopt measures for mitigating the effect of drought.
