Study Notes

Concept of Disaster Risk

Disaster risk is the potential for losses related to life, health, livelihoods, assets, and services in a community over time.
Calculated using the formula: Risk = Probability of Hazard x Degree of Vulnerability.
Risk management strategies include:
- Risk Acceptance: Deciding to accept potential consequences.
- Risk Avoidance: Choosing to not engage in risky activities.
- Risk Reduction: Implementing techniques to minimize risk occurrence and impact.
- Risk Transfer: Shifting the burden of risk to another party, commonly done through insurance.

Hazards

Hazards are situations or phenomena that could potentially cause harm or disruption, such as earthquakes, floods, or terrorist attacks.
When hazards lead to severe damage, they are classified as disasters, acting as sources of risks.

Vulnerability

Represents conditions that increase susceptibility to losses from natural disasters.
Example: Post offices in flood-prone areas are vulnerable to flood impacts.

Exposure

Refers to the presence of people, infrastructure, and assets in hazard-prone areas.
Greater exposure equates to heightened vulnerability.

Risk Triangle

Risk is represented by a triangle consisting of hazard, exposure, and vulnerability.
Increasing any side of the triangle results in a larger area, indicating higher risk, while decreasing any side lowers overall risk.

Aspects of Vulnerability

Vulnerability is shaped by physical, social, economic, and environmental factors, causing variations within communities over time.
Physical Vulnerability: Influenced by population density, infrastructure design, and environmental conditions (e.g., wooden homes better withstand earthquakes but are more fire-prone).
Social Vulnerability: The ability of groups to respond to hazards; marginalized groups (e.g., children, elderly) often face greater challenges during disasters.
Economic Vulnerability: Economic status affects disaster resilience. Individuals in poverty typically reside in unsafe housing and lack resources to prepare for disasters, limiting their ability to recover.
Environmental Vulnerability: Involves the degradation of natural resources, contributing to overall vulnerability to hazards.
