The document discusses various risk factors related to the effects of disasters on human life from different perspectives. Physical factors refer to infrastructure and availability of safety objects. Psychological factors include mental health and perception. Socio-cultural factors involve beliefs, traditions and social status. Economic factors are assets, income and class. Political factors include government structure and diplomacy. Biological factors involve environment, health and diseases. Severity of exposure, gender, age and lack of support influence recovery. Disasters can cause displacement, health issues like disease, food scarcity, and lasting emotional trauma for children. Physical, psychological, socio-cultural, economic, political and biological perspectives provide different lenses for understanding disaster impacts.

1. RISK FACTORS
UNDERLYING DISASTER

2. PHYSICAL FACTORS
•would pertain to tangible objects or
infrastructure, like the availability of
fire exits, or the sturdiness of the
building, or the presence or absence
of objects that can harm you or help
you, etc.

3. PSYCHOLOGICAL FACTORS
•include state of mental capacity and
health (e.g. are we dealing with
babies? Kids? Adults? People with
special needs?), perception of self
(e.g. self-assessment of capability to
respond to disasters, fear), etc.

4. SOCIO-CULTURAL FACTORS
•include religion, social status,
traditions, perception by society, etc

5. ECONOMIC FACTORS
•include assets and liabilities,
income, economic class, etc.

6. POLITICAL FACTORS
•include government structure,
diplomatic issues, etc.

7. BIOLOGICAL FACTORS
•include flora and fauna in
environment, health, diseases, etc.

8. RISK FACTORS

9. SEVERITY OF EXPOSURE
•The amount of exposure to the disaster
is highly related to risk of future mental
problems. At highest risk are those that
go through the disaster themselves. Next
are those in close contact with victims.
At lower risk of lasting impact are those
who only had indirect exposure, such as
news of the severe damage.

10. GENDER AND FAMILY
• Disaster recovery is more stressful when
children are present in the home. Women with
spouses also experience more distress during
recovery. Having a family member in the home
who is extremely distressed is related to more
stress for everyone. Marital stress has been
found to increase after disasters. Also,
conflicts between family members or lack of
support in the home make it harder to recover
from disasters.

11. AGE
• Adults who are in the range of 40 – 60 are
likely to be more distressed after disasters.
The thinking is that if one is in that age range,
he / she has more demands from job and
family. Research on how children react to
natural disasters is still limited at this point in
time. In general, children show more severe
distress after disasters than adults do. Higher
stress in the parents is related to worse
recovery in children.

13. OTHER FACTORS SPECIFIC TO THE
SURVIVOR
oNot functioning well before the disaster.
oHave had no experience dealing with
disasters.
oMust deal with other stressor after the
disaster.
oHave poor self – esteem.
oThink they are uncared by others.
oThink they have little control over what
happens to them.
oLack the capacity to manage stress

14. OTHER FACTORS
oBereavement (death of someone close).
oInjury to self or another family member.
oLife threat.
oPanic, horror, or feelings like that during the
disaster.
oBeing separated from family (especially
among youth).
oGreat loss of property.
oDisplacement (being force to leave home)

15. DEVELOPING COUNTRIES
•There is a strong body of evidence that these
risk factors can be made worse if the disaster
occurs in a developing country. Disasters in
developing countries, like Philippines, have
more severe mental health impact than
disasters in developed countries. This is true
even with less serious disasters.

16. LOW OR NEGATIVE SOCIAL
SUPPORT
•the support of others can be both a
risk and a resilience factor. Social
support can weaken after disasters.
This may be due to stress and the
need for members of the support
network to get on with their own
lives.

17. EFFECTS OF DISASTER TO
HUMAN LIFE

18. DISPLACED POPULATIONS
• One of the most immediate effects of natural
disasters is population displacement. When
countries are ravaged by earthquakes or other
powerful forces of nature like floods and super
typhoons, many people must abandon their
homes and seek shelter in other regions. A
large influx of refugees can disrupt
accessibility of health care and education, as
well as food supplies and clean water.

20. HEALTH RISKS
• Aside from the obvious immediate danger
that natural disasters present, the
secondary effects can be just as damaging.
Severe flooding can result in stagnant water
that allows breeding of waterborne bacteria
and malaria-carrying mosquitoes. Dengue
fever is another serious health problem
cause by mosquitoes (aegis egypti). Without
emergency relief from international danger
has passed.

21. Food Scarcity
After natural disasters, food often becomes scarce.
Thousands of people around the world go hungry
because of destroyed crops and loss of agricultural
supplies, whether it happens suddenly in a storm or
gradually in a drought.
As a result, food prices rise, reducing
families’ purchasing power and increasing the risk of
severe malnutrition. The impacts of hunger following
an earthquake, typhoon or hurricane can be
tremendous, cause lifelong damage to children’s
development.

23. EMOTIONAL AFTERSHOCKS
• Natural disasters can be particularly
traumatic for young children. Confronted
with scenes of destruction and the deaths of
friends and loved ones, many children
develop Post-Traumatic Stress Disorder
(PTSD), a serious psychological condition
resulting from extreme trauma. Left
untreated, children suffering from PTSD can
be prone to lasting psychological damage
and emotional distress.

24. DISASTER FROM THE DIFFERENT
PERSPECTIVE

25. PHYSICAL PERSPECTIVES
- describes observable objects in a building/infrastructure which include
durability of building, fire exits availability, and absence or presence of an
important objects that would help or harm you in any ways. Example:
houses and environmental sources of living. Physical effects are the most
visible and quantifiable effects of a disaster. In considered in data
recording. Assessment of disaster is focused on the following questions:
• How many families are affected? (displacement, injury, death)
• How many houses are damaged or washed out? (in case of super
typhoons)
• How many buildings collapsed or are damaged? (in case of an
earthquake)
• How many roads, bridges, dams and other infrastructures are
damaged? (in case of floods, lahar flows and earthquakes)
• What is the extent of damage in agricultural industry? (crop, losses,

26. PSYCHOLOGICAL PERSPECTIVES
- pertains to the mental capacity and health of an
individual to deal with disasters. Age, perception, and
self-capacity are some of the point of considerations.
In other word, a disaster is something that could
happen within a hazard rather than the hazard itself.
Hence, one very important component of the recovery
phase, aside from relief services is debriefing of
psychological support system.

28. OTHER PSYCHOLOGICAL EFFECTS OF
A DISASTER ARE THE FOLLOWING:
a. Emotional effects: Shock, terror, irritability, blame, anger, guilt, grief or sadness,
numbing, helplessness, loss of pleasure derived from familiar activities, difficulty feeling
happy, difficulty feeling loved.
b. Cognitive effects: impaired concentration, impaired decision-making ability, memory
impairment, disbelief, confusion, nightmares, decreased self-esteem, decreased self-
efficacy, self-blame, intrusive thoughts, memories, dissociation, (e.g.,tunnel vision,
dreamlike or ‘spacey’ felling).
c. Physical effects: fatigue, exhaustion, insomnia, cardiovascular strain, startle response,
hyper arousal, increased physical pain, reduced immune response, headaches,
gastrointestinal upset, decreased appetite, decreased libido, vulnerability to illness.
d. Interpersonal effects: Increased relational conflict, social withdrawal, reduced relational
intimacy, alienation, impaired work performance, decreased satisfaction, distract,
externalization of blame, externalization of vulnerability, feeling abandoned.

29. SOCIO-CULTURAL
PERSPECTIVES
- it involves people’s beliefs, religion, traditions, social status, and
perceptions within a community with respect to considering their
response to disaster.
- What the people living at risk know and do about natural hazards
and disaster risks is mediated by a range of factors including
social conditions (such as age, gender, wealth, ethnicity) and
cultural settings (language, beliefs, traditions, customs). In most
places people are also more or less exposed by information and
ideas coming from the “outside”—the world outside their own
cultural setting. At the same time, the field of natural hazards and
disasters has developed its own debates, framework, and notions
such as vulnerability, resilience, and ‘risk’. But communities may
have different priorities and notions of natural hazards and
disaster risk. People’s socio-cultural background may affect their
response to disasters at the different stages of disaster
management.

30. ECONOMIC PERSPECTIVES
• it involves income, assets and liabilities, and economic
class of an individual or a community in the society.
From an economic perspective, a natural disaster can
be defined as a natural event that causes a
perturbation to the functioning of the economic
system, with a significant negative impact on assets,
production factors, output, employment, and
consumption. One salient component of assessing the
impact of disaster impact from this view is defining
direct economic cost and indirect losses.

31. POLITICAL PERSPECTIVES
• it involves structure of the government, issues in
diplomacy, etc. in dealing with disasters. From this
view, natural disasters are commonly thought to be
less politically contentious than armed conflicts.
Yet, a closer look reveals that politics are deeply
wedded to both the impact of a natural disaster and
the subsequent delivery of humanitarian assistance.
Political considerations before, during, and after a
natural disaster can determine who is most at risk,
who can intervene, what actions will be taken, and
who will benefit from those actions.

32. BIOLOGICAL PERSPECTIVES
– it involves the role of flora (plants) and fauna
(animals) in the environment, diseases, health,
etc. Disasters are not random an do not occur
by accident. They are the convergence of
hazards and vulnerable conditions. Disasters
not only reveal underlying social, economic,
political, and environment problems, but
unfortunately contribute to worsening them.
Such events pose serious challenges to
development, as they erode hard-earned gains
in terms of political, social and educational
progress, as well as infrastructure and
technological development
