Page 29 – Disaster Management: Disaster and Disaster Management

Part 1 – Introduction to Disaster Management, Types of Disasters & Disaster Management Cycle

Disaster Management is one of the most important topics in UPSC General Studies Paper III. India is one of the world's most disaster-prone countries due to its diverse geographical features, long coastline, Himalayan mountain ranges, seismic zones and changing climate. Effective disaster management minimizes the loss of life, property, infrastructure, livelihoods and environmental resources while improving resilience and sustainable development.

Disaster	A hazard causing severe damage beyond local coping capacity.
Risk	Probability of loss due to exposure to hazards.
Vulnerability	Degree to which people or infrastructure are susceptible to hazards.
Capacity	Ability to prepare for, respond to and recover from disasters.
Resilience	Ability to resist, adapt and recover quickly after disasters.

Types of Disasters

Category	Examples
