Assessment & Monitoring of Agricultural Drought Indices Using Remote Sensing Techniques and their Inter-Comparison

Agricultural drought is nothing but the decline in productivity of crops due to irregularities rainfall as well decrease soil moisture, which turn affects economy nation. As Indian agriculture largely dependent on Monsoon, a slight change it production crop yield drastically. The agricultural monitoring, assessment management can be done more accurately with help geospatial techniques like Remote Sensing. In present study estimated vadodara district. purpose analyze vegetation stress Vadodara district calculation NDVI, NDWI, MNDWI, WRI, NDBI and NDSI indices values. results NDVI values shows fields susceptible drought. Similarly, decreasing trend was observed NDWI index 22.12% 19.3% from 2013 2018.The builtup (NDBI) increasing by 1.85% last 5 years. Water ratio also showing area 22.35% 14.29%. intercomparisions all other data provides very useful information for monitoring early warning system farmers. findings this research will interest local authorities, plantation meteorology departments understand drier areas state evaluate water deficits severity cloud seeding points during
