“The wars of twenty-first century will be fought over water“
Water has been the causative of many issues in the world, Karnataka is no different. The infamous Cauvery issue, recurring droughts, crop failure, lack of water for drinking and irrigation etc were very much in the public eye. These issues which have led to many riots and even suicides mostly in districts of Chikkamagaluru, Shivamogga, and Davanagere1, still remain unresolved due to lack of access to historical hydrologic data and lack of research2.
The first step towards the solution is to identify the drought-affected areas spatially. Aapah innovations expertise in microwave remote sensing is capable of preparing the map showing drought-affected areas of the state. The figure shows the soil moisture map of Karnataka as on 9th March 2018. As it is clear from the map that districts of Chikkamagaluru, Shivamogga, and Davanagere have less soil moisture, bespeaking the above statement.
While the state is heading to polling booths today, people especially farmers have set all their hopes on the coming government.
The map is prepared by merging data from multiple satellites using the vikleda algorithm.
Some of the applications where soil moisture is useful are:
- Optimal irrigation in farms
- Identify areas being over-irrigated
- Improved flood risk estimation
- Monitor agricultural drought in near real time
- Improved weather forecast
- Analyse the impact of an irrigation project
- Identify the irrigated area by an irrigation source
- Automatic billing of farm based on the actual irrigation
- Estimation of actual evapotranspiration taking place
- Estimation of area getting degraded
