Groundwater Stress Mapping
Groundwater forms the largest source of freshwater in India, meeting nearly 65% of irrigation, 85% of rural drinking, and 50% of urban water needs. The depletion of aquifers due to over-extraction, pollution, and erratic recharge has led to critical groundwater stress across several regions.
Groundwater stress mapping is a scientific and spatial process used to identify aquifer zones facing imbalance between extraction and replenishment, forming the foundation of sustainable water governance and policy intervention.
Concept and Need for Stress Mapping
- Groundwater stress mapping involves the systematic evaluation of recharge–discharge dynamics, depth to water level, and aquifer characteristics using spatial data.
- The purpose ....
