a serious disruption of the functioning
of a community
Disaster
a natural phenomenon is caused by
natural forces, such as earthquakes,
typhoon, volcanic eruptions, hurricanes,
tornados, extreme temperatures
Natural disaster
source or condition that has the potential to cause harm to humans in the form of injury or illness, property damage, environmental damage, or a combination of these
Hazard
Elements of Disaster risk
-exposure
-hazard
-vulnerability
the “elements
at risk from a
natural or man-
made hazard
event
Exposure
a potentially dangerous phenomenon that may result in loss of life or injury, property
damage, social and economic disruption,
or environmental degradation
Hazard
the condition determined by physical,
social, economic and environmental
factors or processes, which increase the
susceptibility of a community to the
impact of hazard
Vulnerability
are processes or conditions, often
development related, that influence the level of disaster risk by increasing levels of
exposure and vulnerability or reducing capacity
Risk factors
Risk factors
-severity if exposure
-gender and family
-age
-economic status of country
measures those who experience disaster first hand which has the highest risk
of developing future mental problems
Severity of exposure
the female gender suffers more adverse
effects. This worsens when children are present at home
Gender and family
children exhibit stress after disasters
than adults do
Age
severe mental problems resulting from
disasters are more prevalent in
developing countries like the Philippines
Economic status of country
Factors underlie disasters
-climate change
-environmental degradation
-globalized economic development
-poverty and inequality
-poorly planned and manage urban development
-weak governance
-geographical location
The country’s location makes it vulnerable to storms that cause flooding, mudslides, and typhoons
Geographical location
public sector actors
are unable or
unwilling to assume
their roles and
responsibilities in
protecting rights,
providing basic
services and public services
Weak governance
The growing rate of urbanization and the increase in population density (in cities) can lead to creation of risk
Poorly planned and manage urban development
Poverty is therefore
both a cause and
consequence of disaster
risk (Wisner et al., 2004)
• the poor tend to suffer worst from disaster
Poverty and inequality
It results in an increased polarization
between the rich and poor on a global scale
Globalize economic development
changes to the environment can influence
the frequency and intensity of hazards, as
well as our exposure and vulnerability to these hazard
Environmental degradation
-directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition
to natural climate
variability observed over comparable time periods”- UNFCC
-can increase disaster risk– by altering the
frequency and intensity of hazards events,
affecting vulnerability.
Climate change
The effect of natural and man made disasters
-displaced population
-health risk
-food scarcity
-emotional aftershocks
many people need to
abandon their homes and
seek shelter in other
regions.
displaced population
Aside from the obvious immediate
danger that natural disasters present, the
secondary effect can be just as damaging.
