68 % area of India is prone to draught as per Geological Survey of India.
| Flash Drought | Conventional Drought |
|---|---|
| (1) Intensifies over very short duration eg: 2-6 weeks. | (1) Takes long period of time to culminate say- months. |
| (2) Generally multiple factors acting in concert. eg: Low rainfall + Heatwave + Dry spells. | (2) Even one factor prolonged can cause drought eg: Low rainfall over a period of time. |
| (3) Difficult to predict and take precautionary measure | (3) Easier to mitigate by proper water and resource management. eg: National Watershed Management Program. |
Body · points and prose
Vulnerability of India to Flash Drought
Large number of people directly dependant on rain-fed agriculture - 48 % rainfed area.
Already exesebaratiing land desertification (30% area vulnerable- MoES).
Large cattle population depend on direct grazing.
Water security → (Diagram showing bars for 2005 at 1800 lit and 2018 at 1100 lit, with caption "Already water stressed")
Industry like- coal power plant, etc. dependent on water.
Way Ahead:
- Land degradation Atlas to be used for mitigation (ISRO)
- Scientific dam operation and maintenance
- Traditional knowledge - Tanka, Johad, Kuls, etc.
