NADAMS (National Agricultural Drought Assessment and Monitoring System)

  • NADAMS project, developed by National Remote Sensing Centre, provides near real-time information on prevalence, severity level and persistence of agricultural drought at state/ district/sub-district level.

  • Currently, it covers 14 states of India, which are predominantly agriculture based and prone to drought situation (Andhra Pradesh, Bihar, Chhattisgarh, Gujarat, Haryana, Jharkhand, Karnataka, Madhya Pradesh, Maharashtra, Odisha, Rajasthan, Tamil Nadu, Telengana and Uttar Pradesh). Out of which for five states (Andhra Pradesh, Karnataka, Haryana, Maharashtra and Telengana) assessment is being done at Sub-district level.

  • Various indices such as Normalized Difference Vegetation Index (NDVI) derived from NOAA AVHRR data (1km x 1km),Normalized Difference Vegetation Index (NDVI) derived from Resourcesat-2 AWiFS data (56 m), Normalized Difference Vegetation Index (NDVI) and Normalized Difference Wetness Index (NDWI) derived from MODIS (1000/250 m) data, Shortwave Angle Slope Index (SASI) derived from MODIS (500m) data, Soil Moisture Index (derived from soil water balance approach using daily PET & rainfall values),District-level weekly rainfall data from IMD– rainfall deviation, number of dry weeks, taluk/mandal level monthly rainfall data from State Agriculture Departments and crop sown area collected from various states are used for agricultural drought assessment.



  • MNCFC has started providing Drought Assessment Report from the Kharif season of 2012. Fortnightly and monthly drought assessment reports (June to October) were generated and sent to concerned states and national level government agencies.
