ANNOUNCEMENTS
This study aims to identify Drought Vulnerability Assessment of Rajasthan using Geospatial Technique. An efficient method for disaster monitoring is the analytic hierarchy process (AHP) in combination with geographic information system (GIS). The Rajasthan state of India is taken where drought was analysed spatially in the current study using GIS. Thematic maps were created for each of the nine criteria, which included yearly rainfall, maximum temperature, elevation, aspect, surface water, soil moisture, land use landcover, slope, groundwater depth. AHP was used to create pairwise comparison matrices and determine each parameter's weighting factors. Using the unique indices, various types of drought vulnerability maps were created. Finally, the spatial analysis was used to combine the indicators and create the overall drought vulnerability map.
The final output map shows that the normal contains approx. 2450 sq. km of the area, mild contains approx. 9924 sq. km of the area, moderate contains approx. 35492 sq. km of the area, severe contains approx. 142188 sq. km of the area, extreme contains approx. 152439 sq. km of the area.
