India’s climate resilience requires linking monsoon forecasting, disaster management and urban infrastructure. Analyse this requirement using the northeast monsoon and Bay of Bengal cyclone risk. (250 words)

Answer

Introduction

The northeast monsoon supplies a major share of rainfall to the southeastern peninsula, while Bay of Bengal systems can rapidly intensify. Both demand forecast-led, locally implemented resilience.

Climatic And Geographical Context

  • October–December rainfall is concentrated in Tamil Nadu, Puducherry, coastal Andhra Pradesh, Rayalaseema, south interior Karnataka and Kerala.
  • El Niño often weakens the southwest monsoon but has an uncertain relationship with the northeast monsoon; historical variability makes seasonal averages insufficient.
  • Warm seas, coastal exposure and dense urbanisation amplify cyclone, flood and storm-surge risks.

Governance And Infrastructure Gaps

  • Forecast uncertainty is wider for the northeast monsoon than for the southwest monsoon.
  • Blocked drains, encroached wetlands, weak shelters and fragmented inter-State coordination convert heavy rain into urban disaster.
  • Evacuation must reach informal settlements, elderly persons, children and persons with disabilities.

Integrated Resilience Strategy

  1. Combine IMD nowcasts with district-level impact forecasts and transparent uncertainty communication.
  2. Pre-position SDRF/NDRF teams, shelters, medicines, power backups and resilient communications.
  3. Restore wetlands, clear stormwater channels and enforce risk-sensitive coastal and urban planning.
  4. Institutionalise after-action reviews and coordinate Centre, States, municipalities and communities.
