UPSC Previous Year Question | Mains GS1 | 2016

Major cities of India are becoming more vulnerable to flood conditions. Discuss. (200 words)

Answer

Introduction

Indian cities face increasing flood risk because intense rainfall meets impermeable surfaces, encroached drainage and weak urban planning.

Causes And Impacts

Urban vulnerability

  • Wetland loss, blocked drains, construction on floodplains, inadequate capacity and poor solid-waste management intensify runoff.
  • Sea-level rise, storm surges, tidal backflow and changing rainfall extremes compound coastal risks.
  • Floods damage housing, transport, electricity, health services and informal livelihoods while spreading disease.

Solutions

Resilience

  • Restore wetlands and blue-green corridors; enforce floodplain zoning and permeable, water-sensitive design.
  • Upgrade drains using basin-level modelling, maintain outfalls and improve solid-waste collection.
  • Early warning, evacuation, resilient infrastructure and coordinated municipal governance are essential.
