Question 14GS3GS1
Enumerate the reasons behind rising intensity and frequency of cyclones in the Arabian Sea in recent years. Giving special reference to NDMA guidelines, recommend measures to check the adverse impacts of cyclones.
Introduction
Arabian Bay of Bengal has been harbour of cyclones but in recent years cyclone frequency in Arabian sea has also increased.

Main Body
[Reasons]
1climate change induced uncertainties
(a) El-Nino & La Nina patterns
2Indian Ocean dipole impact
3Low pressure conditions due to risen temperature (11°C already scaaling - IPCC)
4Local heating conditions also increases frequency.
5Changes in atmospheric circulations primary & secondary circulation (eg Trade winds)
All these require multidimensional measures to check adverse impact —
1[NDMA guidelines]
(a) Cyclone Risk Mitigation Plan
at state, national & local level.
2Cyclone shelters for relief & recovery.
3Early Warning systems for quick response.
2[Mitigation measures]
(a) Structural - conducting cyclone walls to minimise impact - Bioshields - Mangroves
2[Non-structural measures]
(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.
