Study Notes
Disaster Risk Elements
- Disaster risk consists of three important elements: exposure, hazard, and vulnerability.
- Exposure refers to the "elements at risk from a natural or man-made hazard event".
Hazard
- A hazard is a potentially dangerous physical occurrence, phenomenon, or human activity that may result in:
- Loss of life or injury
- Property damage
- Social and economic disruption
- Environmental degradation
Vulnerability
- Vulnerability is the condition determined by physical, social, economic, and environmental factors or processes that increase the susceptibility of a community to the impact of a hazard.
Risk Reduction
- Reducing the level of vulnerability and exposure can be achieved by keeping people and property as distant as possible from hazards.
- Addressing the reduction of risk and exposure involves determining the factors causing disasters.
Risk Factors
- Risk factors are processes or conditions that influence the level of disaster risk by increasing levels of exposure and vulnerability or reducing capacity.
- These factors include:
- Severity of exposure
- Gender and Family
- Age
- Economic status of country
Severity of Exposure
- Severity of exposure measures the level of risk for developing future mental problems, with those who experience disaster first-hand being at the highest risk.
- Those in contact with victims, such as rescue workers and healthcare practitioners, have a lower risk.
- Those most distant, with awareness only through news, have the lowest risk.
Gender and Family
- The female gender suffers more adverse effects, which worsens when children are present at home.
- Marital relationships are placed under strain.
Age
- Adults in the age range of 40-60 are more stressed after disasters.
- Children exhibit more stress after disasters than adults do.
Economic Status of Country
- Severe mental problems resulting from disasters are more prevalent in developing countries.
- Natural disasters tend to have more adverse effects in developing countries than man-made disasters in developed countries.
