Part 1 – Disaster Management: Meaning, Types of Disasters, Disaster Cycle & Principles of Disaster Risk Reduction

Disaster Management is one of the most important topics in UPSC General Studies Paper III. India is highly vulnerable to natural and human-induced disasters because of its diverse geography, long coastline, Himalayan mountain range, rapidly growing urban population and changing climate. Effective disaster management minimizes loss of life, property, environment and livelihoods while strengthening resilience for sustainable development.

India has shifted from a relief-centric approach to a proactive strategy emphasizing prevention, mitigation, preparedness, response, recovery and resilience. This approach aligns with the Sendai Framework for Disaster Risk Reduction (2015–2030) and the Sustainable Development Goals (SDGs).
