DISASTER MANAGEMENT — PREVENTION, PREPAREDNESS, RESPONSE AND RECOVERY
1. Meaning of Disaster
- A disaster is a serious disruption caused by natural or human-induced events that results in substantial loss of life, property, livelihoods or the environment.
- The Disaster Management Act, 2005 defines disaster in terms of a catastrophe, mishap, calamity or grave occurrence beyond the coping capacity of the affected community. (India Code)
- A hazard becomes a disaster when it interacts with exposure, vulnerability and inadequate coping capacity.
2. Major Types of Disasters
- Natural disasters include earthquakes, floods, cyclones, droughts, landslides, avalanches, heat waves and tsunamis.
- Human-induced or technological disasters include industrial accidents, chemical leaks, fires, nuclear or radiological emergencies and transport accidents.
- Biological emergencies such as epidemics and pandemics may also require large-scale disaster-management measures.
3. Meaning of Disaster Management
- Disaster management is a continuous and integrated process involving planning, coordination and implementation of measures to reduce disaster risk.
- It includes prevention, mitigation, preparedness, response, evacuation, rescue, relief, rehabilitation and reconstruction.
- The emphasis has gradually shifted from a purely relief-centred approach to risk reduction and resilience building.
- NCERT material similarly emphasises prevention, preparedness, community participation, knowledge and environmental sustainability. (NCERT)
4. Disaster Management Cycle
- The disaster-management cycle can broadly be understood through prevention/mitigation → preparedness → response → recovery.
- Mitigation aims to reduce the severity of future losses through measures such as safer buildings, embankments, land-use planning and ecosystem protection.
- Preparedness includes early-warning systems, emergency plans, mock drills, evacuation routes and training.
- Response covers immediate rescue, relief, medical aid and restoration of essential services.
- Recovery includes rehabilitation, reconstruction and restoration of livelihoods.
