BharatNotes Overview
Disaster Management encompasses the prevention, mitigation, preparedness, response, relief, and rehabilitation measures taken before, during, and after a disaster. India is among the most disaster-prone countries in the world, with nearly 58.6% of its landmass susceptible to earthquakes and over 40 million hectares prone to floods.
This topic is divided into 18 detailed chapters covering the full spectrum of GS3 Disaster Management. Work through them sequentially for a complete understanding, or jump to any chapter for targeted revision.

Exam Strategy: Disaster Management is a consistent GS3 Mains topic. Prelims tests institutional facts (NDMA chair, NDRF battalions, Sendai targets, SDRF ratios). Mains demands case-study-based answers — always cite the Odisha cyclone transformation (1999 vs 2019) and link disaster management with climate change. For every answer, present both institutional framework and community-level preparedness dimensions.
