Disasters are complex phenomenon with
multiple causes and consequences
India is one of the most disaster prone country
in the world.

4. Disasters -natural or human-made are common
throughout the world.
Increase in their magnitude, complexity, frequency and
economic impact.
Second half of the 20
th
century-200 worst natural
disasters 1.4 million people dead.
Asia tops the list of casualties due to natural disasters

6. Last thirty years -431 major disasters resulting into
enormous loss to life and property.
1,43,039 people were killed and about 150 crore were
affected by various disasters in the country during these
three decades
Highly vulnerable to floods, droughts, cyclones,
earthquakes, landslides, avalanches and forest fires
57% land is vulnerable to earthquakes. Of these, 12% is
vulnerable to severe earthquakes.
68% land is vulnerable to drought.
12% land is vulnerable to floods.

7. 8% land is vulnerable to cyclones.
Apart from natural disasters, some cities in India are also
vulnerable to chemical and industrial disasters and man-
made disasters.
Floods, earthquakes, cyclones, hailstorms, etc. are the
most frequently occurring disasters in India.
India is one of the ten worst disaster prone countries of
the world.

“Any occurrence that causes damage,
ecological disruption, loss of human life or
deterioration of health and health services on a
scale sufficient to warrant an extraordinary
response from outside the affected community
or area.”

Disaster Cycle

25. Chances of survival after a disaster are greatly
improved when people, local governments
and emergency services, businesses and
national governments prepare survival plans
and assemble survival gear beforehand.
What constitutes sufficient preparation is
highly dependent on the location and the
disasters that are likely to occur in the area.

26. Most natural disaster recur in same areas
Impossible to prevent, but…
Can reduce their effects by being prepared

28. Disaster Prevention: aimed at impeding the occurrence of a disaster
event and/or preventing such an occurrence having harmful effects on
communities. (long-range policies and programs.)
Disaster Mitigation : Measures aimed at reducing the impact of a
natural or man-made disaster on a nation or community.
Disaster Preparedness : Measures, which enable governments,
organizations, communities and individuals to respond rapidly and
effectively to disaster situations.
Disaster Response : Response measures are those, which are taken
immediately, prior to and following disasters.
◦saving life and protecting property and dealing with the immediate
damage

29. Social reactions :
These could be grouped as follows :
(i) Spontaneous behavioral reactions e.g.
generalized panic or stunned waiting.
(ii) Widespread looting
iii) Rumors regarding spread of epidemic
(iv) Population displacements leading to excessive
burden on
relatives and friends, parks city squares, vacant
lots and
government buildings in urban areas where public
services can’t cope resulting in increased morbidity
and mortality.

30. Exposure to elements : The need to provide
emergency shelter varies greatly with local
conditions.
Food and Nutrition : Food shortages in the
immediate aftermath or Food stock destruction

48. Public Health Aspects following
a Disaster

49. The displaced population must be sheltered in temporary
settlements or camps.
sites must be well planned to avoid risk factors for
communicable diseases transmission, such as
◦overcrowding, poor hygiene and inadequate water supply,
◦insanitary disposal of excreta, vector, inadequate sites and lack of
adequate shelter.
Critical factors: water availability, means of transport,
access to fuel and access to fertile soil.

51. Water and sanitation are vital elements in the
transmission of communicable diseases
Diarrheal diseases are a major cause of morbidity and
mortality among affected populations
Main objective is to reduce these transmissions through
◦Promotion of good hygiene practices,
◦Provision of safe drinking water
◦Reduction of environmental health risks
◦Establishing conditions that allow people to live with
good health, dignity, comfort and security

52. Assuming water point is accessible for
approximately eight hours a day
-250 people per tap based on a flow of 7.5
lt/min
-500 people per handpump based on a
flow of 16.6 lt/min
-400 people per single-user open well
based on a flow of 12.5 lt/min

55. There is a correlation between improper solid waste
disposal and the incidence of vector-borne diseases.
Arrangements must be made to collect, store and dispose
of solid waste.
Assess the situation, considering the number of people in
the shelter, existing services, collection service,
topographic conditions, accessibility and soil type
Estimate the quantity, type and capacity of the water
storage containers
The capacity of the containers should be 50-100 liters
and should not exceed 20-25 kg when full.

56. Provide three or four containers per 100 persons and
distribute
The containers should not touch the ground, for example
they should be on a wooden platform. They must be
emptied and washed daily
Dead animals and excrement from domestic animals
must be buried immediately, since they can be a source
of contamination.
Provide information and training to the population on
sanitary refuse handling.

57. Food shortages and malnutrition are common features of
emergency situations.
Micronutrient deficiencies such as iron-deficiency
anaemia, pellagra, scurvy and vitamin A deficiency are
common
Food is also an important source of pathogens and there
is a risk of diarrhoeal disease epidemics when basic food
safety principles are not followed

58. To overcome this menace following actions are
recommended :
Ensure an adequate water supply.
When preparing food or washing utensils, use a
chlorinated water supply.
Store food in sealed containers.
Ensure that food is covered during cooking and prior to
serving.
Ensure that cooked food is consumed once prepared.
Cover food when served, if left unattended.

59. Cover water containers at all times.
Ensure that water is taken either from a tap or from a
clean container.
Disposal of garbage safely.
Place hand-washing facilities outside latrines, living areas
and kitchens.
Ensure an adequate number of sanitary latrines and that
they are maintained and used.
All areas in a feeding centre must be cleaned daily using
chlorine as a disinfectant.

60. Estimates for average population
requirements should be used
◦2,100 kcals per person per day
◦10-12% of total energy provided by protein
◦17% of total energy provided by fat
◦adequate micronutrient intake through fresh or
fortified foods.
◦Infants, children, pregnant women, nursing mothers and
sick persons should be given special attention

61. A maximum of 20 -50 people use each toilet
Use of toilets is arranged by household(s)
and/or segregated by sex
Separate toilets for women and men are
available in public places
Shared or public toilets are cleaned and
maintained in such a way that they are used
by all intended users
Toilets are used in the most hygienic way and
faeces are disposed of immediately and
hygienically

62. Toilets are no more than 50 metres from
dwellings
They are designed in such a way that
they can be used by all sections of the
population, including children, older
people, pregnant women and physically
and mentally disabled people
They are sited in such a way as to
minimise threats to users, especially
women and girls, throughout the day and
night
They are sufficiently easy to keep clean

63. Pit latrines and soakaways (for most soils) are
at least 30 metres from any groundwater
source and the bottom of any latrine is at
least 1.5 metres above the water table
People wash their hands after defecation and
before eating and food preparation

64. Hygiene through the participation of the
community
As a rough guide, in a camp scenario there
should be two hygiene
promoters/community mobilisers per 1,000
members of the target population

65. The major biological vectors are mosquitoes, sand flies,
ticks, fleas, lice, mites.
The diseases most commonly spread by vectors are
malaria, filariasis, dengue fever, leishmaniasis, typhus
and plague.
Major diseases transmitted by intermediate hosts or
carriers are schistosomiasis, diarrhoeal diseases and
trachoma.
Prevention:
◦Residual spraying,
◦Personal protection,
◦Environmental control,
◦Camp site and shelter design and layout,
◦Community awareness.

66. People avoid exposure to mosquitoes during
peak biting times by using all non-harmful
means available to them.
Control of human body lice is carried out
where louse-borne typhus or relapsing fever
is a threat
Bedding and clothing are aired and washed
regularly
Food is protected at all times from
contamination by vectors such as flies,
insects and rodents
Special attention of high-risk groups such as
pregnant and feeding mothers, babies,
infants, older people and the sick

67. Overcrowding
Migration / displacement
Water supply disruption / contamination
Routine control programme disruption
Ecological changes
Displacement of domestic and wild animals
Emergency food and water

68. Setting up a Surveillance System
Disease Surveillance
Vaccinations and Vaccination Programs
Not effective on a large scale
Implementation issues
False sense of security
Advised for health workers
Burial / Disposal of the Dead

69. Acquisition of supplies
Transportation
Storage
Distribution

70. Rehabilitation begins immediately after a
disaster
Restoration to pre-disaster state
The health care needs keep changing rapidly
following a disaster

74. Mitigation: comprises measures taken in advance of a
disaster aimed at decreasing or eliminating its impact on
society and the environment.
Mitigation is generally categorisedinto two main types of
activities i.e. structural and non-structural.
Structural Mitigation: physical construction and
engineering measures and construction of hazard-
resistant protective structures and infrastructure.
Nonstructural mitigation: policies, awareness, knowledge
development, public commitment and methods and
operating practices

75. Earthquakes

reducing the vulnerability in the high risk districts prone to
earthquakes
◦techno-legal regime, institutional strengthening, capacity building
and public awareness etc.
National Building Code (NBC): national instrument
providing guidelines for regulating the building
construction activities across the country

76. National Flood Risk Mitigation Project (NFRMP): mobilise
the resources and capability for relief, rehabilitation,
reconstruction and recovery from disasters besides
creating awareness among vulnerable communities
Flood Management Programme : Provide protection to
flood prone areas

Building codes
Safety of water supply and sewage systems
Planning

79. “a programme of long term development
activities whose goals are to strengthen the
overall capacity and capability of a country to
manage efficiently all types of emergency. It
should bring about an orderly transition from
relief through recovery, and back to sustained
development.”

80. Forecasting about climate change is pre requisite for taking preparedness measure
to respond to the disaster is the most important element of disaster management.

81. Achieve a satisfactory level of readiness to
respond to any emergency situation through
programmes that strengthen the technical
and managerial capacity of governments,
organizations, institutions and communities.
