Soil Moisture Conditions in Northern Karnataka and
Crop Cover in Southern Karnataka as on 18thApril 2016
During the first meeting of Karnataka – Geographic Information System (K-GIS)
Empowered Committee, the Chief Secretary, Govt. of Karnataka has instructed KSRSAC to
provide information on soil moisture stress in northern districts of Karnataka and area under
crops in southern districts of Karnataka for the month of April 2016.
In view of the instructions, for the third report using the satellite image AWiFS (56m) dated
18th April 2016, KSRSAC has carried out the following;
Assessment of soil moisture stress conditions in 12 northern districts (Bidar,
Ballari, Belagavi, Bagalakot, Dharwad, Gadag, Haveri, Kalaburgi, Koppal,
Vijayapura, Raichur and Yadgir) of Karnataka.
Estimation of area under crop in 10 southern districts (Bengaluru Urban,
Bangaluru Rural, Kolar, Chikkaballapur, Chamarajanagar, Hassan, Mandya,
Mysore, Ramanagra and Tumakuru) of Karnataka.
State-wide Soil Moisture Stress Conditions
State-wide assessment of soil moisture stress conditions as on as on 18th April2016 is given in
fig-1 and table-1. It is seen that 97.2% of the Karnataka State is under moderate and severe
soil moisture stress conditions, an increase of 6.4% as compared to 30th March 2016.
