UNIT 1: LESSON 1

4. OBJECTIVES
By the end of the lesson, the students must be able to:
• Explain the basic concept about disaster , disaster risk,
and vulnerabilities
• Determine the various elements vulnerable to disaster
• Identify the capacities that can help reduce disaster risk
and losses.

5. QUESTIONS
• When does natural event become
a hazard?
• When does a hazard become a disaster?

6. WHAT IS DISASTER ?
“ It is a serious disruption of the functioning of a
community or society causing widespread human,

9. TYPES OF VULNERABILITIES
• Physical and Environmental vulnerability
• Social vulnerability
• Economic vulnerability

10. PHYSICAL AND ENVIRONMENTAL
VULNERABILITIES
• These refer to the human made environment of buildings
and infrastructure and the natural environment of
agriculture, forestry and aquaculture.
Factors affecting magnitude of Physical Vulnerability:
a. Geographic Pattern of the severity of the hazard
b. Exposure of the elements to hazards
c. Geological and environmental characteristics of the community
d. Effects of Local conditions

11. SOCIAL VULNERABILITY
• It refers to the susceptibility of the population, the social
institutions or organizations that ensure the sustenance of the
families, communities and society.
1. Special Categories of vulnerable groups of people
2. Educational Attainment

12. ECONOMIC VULNERABILITY
• It pertains to the assets and resources of the community that
are susceptible to disasters, including production, distribution
and utilization of goods and services that ensure the well
being of the people .
Factors affecting economic vulnerability:
1. Sources of Livelihood
2. Community Resources
3. Household Income and Savings
4. Markets and Access to goods and
services

13. DISASTER FORMULA
VULNERABILITY + HAZARD =
DISASTER
CAPACITY

15. WHAT IS DISASTER RISK ?
• It is the probability of harmful consequences or
expected losses (deaths, injuries, livelihoods, assets,
and services) resulting from the interactions between
natural or human-induced and vulnerable conditions.

16. DISASTER RISK FORMULA
HAZARD + EXPOSURE + VULNERABILITY = DISASTER RISK

17. HOW TO REDUCE DISASTER RISK?

18. DISASTER RISK REDUCTION
• A proactive approach being adopted , where risks are
reduced and managed.
• The risk could be high, medium, or low, depending on
physical, environmental, and socio-economic factors.

19. RISK FACTORS
1. Environmental problems
• Declining ecosystem
• Social
• Economic vulnerabilities
• Climate change

20. RISK FACTORS
2. Human factors
• Unplanned urbanization
• Under-development / poverty

21. RECOMMENDED MEASURES
• 1. Lessen the rate of vulnerability by empowering people in disaster
risk reduction
• 2. Keep exposure away from hazard by relocating people and
property

22. RECOMMENDED MEASURES
• 3. develop disaster preparedness
• 4. Empower the people.
