Main Body
[Reasons]
(a) El-Nino & La Nina patterns
All these require multidimensional measures to check adverse impact —
(a) Cyclone Risk Mitigation Plan
at state, national & local level.
(a) Structural - conducting cyclone walls to minimise impact - Bioshields - Mangroves
(a) Color-coded warnings (IMD)
(b) State-Wide Area Network (SWAN)
(c) Integrating cyclone management planning in state & local body budget.
(d) Constituting Mitigation fund (ISt Financial Commission)
Conclusion
India with 10% world cyclone is highly prone due to 5100km/1512kms coastline vulnerable to cyclones. This requires implementation of above measures to ensure EDG 13 (climate action), 14 (life below water) & 15 (life on land) by 2030.
