Water Intelligence for Indian Farming: Smarter Irrigation
Why in the news
India’s farm sector consumes close to 80% of freshwater but irrigates at about 38% efficiency, so the argument now favours smarter water management over mere access to water.
Key issues
- Groundwater overuse: unregulated extraction depletes aquifers, mainly in north-western states.
- Low efficiency: flood irrigation wastes water and cuts productivity.
- Climate variability: erratic rain deepens scarcity and hits farm incomes.
Components of water intelligence
| Component | Role |
|---|---|
| Monitoring | Sensors, drones, IoT: live soil moisture, weather and water-use data |
| Predictive analytics and AI | Forecast irrigation needs, optimise schedules, cut wastage |
| Automation | Mobile-enabled pump controls, automated drip irrigation |
| Smart practices | Precision farming: lower input costs, better water-use efficiency |
Significance
- Less groundwater over-extraction; long-term resource care.
- Lower water and energy costs, yields held.
- Better adaptation to climate-driven water stress.
