Introduction
Capacity plays a crucial role in reducing disaster impacts. While hazards and vulnerability increase disaster risk, capacity helps individuals, communities, and institutions prepare for, respond to, and recover from disasters.
Capacity
Definition: Capacity refers to the strengths, resources, skills, knowledge, and abilities available within a community, organization, or system that can be used to anticipate, cope with, resist, and recover from the impacts of disasters.
Types of Capacity: • Physical: Strong buildings, roads, hospitals. • Social: Community cooperation, volunteer networks. • Economic: Financial resources, insurance. • Institutional: Disaster response agencies, early warning systems. • Technological: Communication systems, forecasting tools.
Relationship between Capacity, Hazard, Vulnerability, and Risk
Formula: Disaster Risk = (Hazard x Vulnerability) / Capacity
• Higher capacity → Lower disaster risk • Lower capacity → Higher disaster risk
Disaster and Development
Disaster and development are interrelated.
• Poor Development Increases Disasters: Unplanned urbanization, poor housing, environmental degradation. • Good Development Reduces Impact: Strong infrastructure, education, poverty reduction. • Disaster–Development Cycle: Disasters damage development; poor development increases losses; sustainable development breaks this cycle.
Disaster Management & Phases
Definition: Organized process to reduce disaster impacts.
Phases:
- Prevention & Mitigation: Risk assessment, building codes.
- Preparedness: Training, drills, early warning.
- Response: Search and rescue, medical aid.
- Recovery: Rehabilitation, reconstruction.
Role of Capacity
• Improves preparedness and response. • Speeds up recovery. • Promotes self-reliance.
Summary
• Capacity is the ability to manage disasters effectively. • Higher capacity reduces disaster risk. • Capacity building is essential for sustainable societies.
