daily lesson log in science disaster readiness and risk reduction

1. EXPOSURE AND VULNERABILITY ALWAYS FIRST ALWAYS READY ALWAYS THERE

2. Module II: Exposure and Vulnerability Elements exposed to hazards Social, environmental, and economic dimensions of exposure and vulnerability Causes of vulnerability

3. Elements at Risk People Properties Economic activities Public and private services

4. Exposure = total population living in the affected area for each event Exposure = probability of occurrence of an event at a given magnitude Hazard = physical exposure for the affected area PhExp = Hazard x Exposure HExp

5. Physical Elements Exposed to Hazard Essential Facilities Educational facilities Medical and healthcare facilities Emergency response facilities Recreational or tourist facilities Places of worship Banks and financial centers Markets and shopping centers Cemeteries

6. Physical Elements Exposed to Hazard Industrial and high potential loss facilities containing hazardous materials dams and ponds fuel reservoirs, pipelines, and pumps power generating plants and lines multi-purpose hydropower plants, water tanks, and lines food processing facilities

7. Physical Elements Exposed to Hazard Transportation lifelines h ighways, bridges, railway tracks, and tunnels bus facilities port and harbor facilities airport facilities and runways

8. Physical Elements Exposed to Hazard Utility lifelines potable water facilities, waste water facilities, pipelines, and distribution lines oil and natural gas systems facilities, pipelines, and distribution lines electric power facilities and distribution lines communication facilities and distribution lines

9. Elements at Risk People Properties Economic activities Public and private services disaster risk = Hazard x exposure x vulnerability

10. Dimensions of Exposure and Vulnerability V E

11. Dimensions of Exposure and Vulnerability SOCIAL Migration Social groups Health and well-being Education Culture Institutions Governance Demography ENVIRONMENTAL Location Built structures Low-lying areas Coastal regions Mountainous areas ECONOMIC Business interruptions Loss of jobs and access to work Loss of government income Significant effect to gross domestic product (GDP)

12. Vulnerability The degree of loss to each element should a hazard of a given severity occur. Physical, social, economic and environment factors determine the likelihood and severity of damage due to a given hazard.

13. Factors of Vulnerability SOCIAL People with disabilities Children Seniors Medication-dependent individuals Women Ethnic minorities, aboriginal or indigenous people Homeless or street people Incarcerated individuals Marginalized groups

14. Factors of Vulnerability ENVIRONMENTAL Relative inability to adapt to changes Rapid urbanization in hazardous areas Quintupling of world’s urban population Increasing number of informal settlers

15. Factors of Vulnerability ECONOMIC Economic vulnerability is the susceptibility of individuals, communities, businesses, and governments to absorb or cushion the effects of a hazard event Rural households are more vulnerable than those in urban because of greater number of people living in poverty Women are more vulnerable than men because they lack access to livelihood

16. World Risk Index 2016

17. World Risk Index 2016 The country is listed in the number three spot, making it one of the most disaster-prone countries on earth. The higher a country is ranked in this index, the greater the chance that its inhabitants will die in a natural disaster
