Natural disaster impacts by disaster sub-group: 2015 versus
2005-2014 annual average

Keyur Nagecha
V. V. P. Engineering College: Rajkot
What is Disaster?
•A serious disruption of the functioning of a society, causing
widespread human, material, or environmental losses which
exceed the ability of the affected society to cope using only its own
resources
•The United Nation defines disaster as “the occurrence of a sudden
or major misfortune which disrupts the basic fabric and normal
functioning of a society (community).”

Keyur Nagecha
V. V. P. Engineering College: Rajkot
What is Disaster?
•As per Disaster Management Act, 2005
–“Disaster” means a catastrophe, mishap, calamity or grave
occurrence in any area, arising from natural or man-made causes, or
by accident or negligence which results in substantial loss of life or
human suffering or damage to, and destruction of, property, or
damage to, or degradation of, environment, and is of such a nature or
magnitude as to be beyond the coping capacity of the community of
the affected area

Keyur Nagecha
V. V. P. Engineering College: Rajkot
What is Disaster?
•A disaster happens when a hazard impacts on the vulnerable
population and causes damage, casualties and disruption.
•Any hazard -flood, earthquake or cyclone which is a triggering
event along with greater vulnerability (inadequate access to
resources, sick and old people, lack of awareness etc.) would lead
to disaster causing greater loss of life and property.
–For example, an earthquake in an inhabited desert cannot be
considered a disaster, no matter how strong the intensities produced.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
What is Disaster?
–An earthquake is disastrous only when it affects people, their
properties and activities.
–Thus, disaster occurs only when hazards and vulnerability meet.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
What is Disaster?
•With greater capacity of the individual/ community and
environment to face these disasters, the impact of a hazard
reduces.
•three major components of understanding disaster management
–hazard,
–vulnerability and
–capacity

Hazard
•A rare or extreme natural event that threatens to adversely affect
human life, property or activity to the extent of causing a disaster
•or
•Potentially damaging events loss of life/injury, Property damage
social and economic disruption Environmental degradation
•Examples are heavy rainfall, Earthquake, landslide, Forest fire,
Tsunami etc…..

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Hazard
•A natural hazard pertains “to a natural phenomenon which occurs
in proximity and poses a threat to people, structures and economic
assets caused by biological, geological, seismic, hydrological or
meteorological conditions or processes in the natural
environment.”

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Hazard
•There are four types of hazardous events that put societies at risk:
–1. Those based in nature: earthquake, droughts, floods, etc.
–2. Those based in violence: war, armed conflict, physical assaults, etc.
–3. Those based in deterioration: environmental degradation declining
health, education and other social services.
–4. Those based in failing industrialized society: fire, gas leakage,
transport collisions, etc.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Hazard
•The extent of damage from a disaster depends on:
–1. The impact, intensity and characteristics of the phenomenon, and
–2. How people, environment and infrastructure are affected by that
phenomenon
•The relationship between hazard and vulnerability is best
represented as an equation:
•Hazard> Disaster< Vulnerability
•Or
•Disaster Risk =Hazard +Vulnerability

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Vulnerability
•1. Physical Vulnerability
–It includes notions of who and what may be damaged or destroyed
by natural hazard such as earth-quakes or floods.
–It is based on the physical condition of people and elements at risk,
such as buildings, infrastructure etc. and their proximity, location and
nature of the hazard.
–It also relates to the technical capability of building and structures to
resist the forces acting upon them during a hazard event

Vulnerability
–Physical vulnerability cont….
–Unchecked growth of settlements in unsafe areas exposes the people
to the hazard.
–In case of an earthquake or landslide the ground may fail and the
houses on the top may topple or slide and affect the settlements at
the lower level even if they are designed well for earthquake forces

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Vulnerability
•2. Socio economic Vulnerability:
–The degree to which a population is affected by a hazard will not
merely lie in the physical components of vulnerability, but also on the
socio-economic conditions.
–The socio-economic condition of the people also determines the
intensity of the impact.
–For example, people who are poor and living in the seacoast don’t
have the money to construct strong concrete houses.
–They are generally at risk and loose their shelters whenever there is
strong wind or cyclone.

Risk
•The probability of harmful consequences, or expected losses
(deaths, injuries, property, livelihoods, economic activity disrupted
or environment damaged) resulting from interactions between
natural or human induced hazards and vulnerable conditions is
known as risk
•It is a combination of the probability of an event and its negative
consequences.
•RISK = HAZARD x VULNERABILITY

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Risk
•Risk is a measure of the expected losses due to a hazard event
occuringin a given area over a specific time period.
•The level of risk depends upon :
–Nature of the hazard
–Vulnerability of the elements which are affected
–Economic value of those elements
•A community/locality is said to be at risk when it is exposed to
hazards and is likely to be adversely affected by its impact

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Risk
•he word “risk” has two distinctive connotations:
–in popular usage
•chance or possibility, such as in the risk of an accident
–technical settings
•consequences in terms of “potential losses” for some particular cause
place and period.
•It can be noted that people do not necessarily share the same
perceptions of the significance and underlying causes of different
risks

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Risk Management
•Risk management.
–The systematic approach and practice of managing uncertainty to
minimize potential harm and loss is called Risk management.
–It comprises risk assessment and analysis, and the implementation
of strategies and specific actions to control, reduce and transfer risks.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Risk Management
•It is widely practiced by organizations to minimize risk in
investment decisions and to address operational risks such as those
of business disruption, production failure, environmental damage,
social impacts and damage from fire and natural hazards.
•Risk management is a core issue sectors such as water supply,
energy and agriculture whose production is directly affected by
extremes of weather and climate

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster Risk Reduction
•The concept and practice of reducing disaster risks through
systematic efforts to analyze and manage the casual factors of
disasters, including through reduced exposure to hazards, lessened
vulnerability of people and property, wise management of land and
the environment and improved preparedness for adverse events, is
termed as disaster risk reduction.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster Risk Reduction
•Disaster risk reduction consists of the following components
–(a) Disaster risk analysis
–(b) Disaster risk prevention
–(c) Disaster risk preparedness

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster Risk Reduction: 1.Risk assessment / Analysis
•Risk assessment / analysis
–A methodology to determine the nature and extent of risk by
analyzing potential hazards and evaluating existing conditions of
vulnerability that could pose a potential threat or harm to the
people, property, livelihoods and the environment on which they
depend.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster Risk Reduction: 1.Risk assessment / Analysis
•It includes
–A review of (ho technical characteristics of hazards such as their
location, intensity, frequency and probability.
–.The analysis of exposure and vulnerability including the physical
social, health, economic and environmental dimensions.
–Evaluation of the effectiveness of prevailing and alternative coping
capacities in respect to likely risk scenarios

Disaster Risk Reduction: 2. Prevention & Mitigation
•Mitigation and prevention efforts aim to reduce the potential
damage and suffering that disasters can cause.
•While disaster management cannot prevent disasters, it can
prevent them from becoming compounded as a result of neglecting
causal factors and manageable risks.
•Mitigation specifically refers to actions taken that can lessen the
severity of a disaster’s impact.
•Investing in measures that limit hazards can greatly reduce the
burden of disasters.

Keyur Nagecha

Disaster Risk Reduction: 2. Prevention & Mitigation
•Strategies that disaster management professionals implement to
protect vulnerable communities and limit hazards include the
following:
–Raising awareness about potential hazards and how to address them
–Educating the public about how to properly prepare for different
types of disaster
–Installing and strengthening prediction and warning systems

Keyur Nagecha

Capacity
•Physical Capacity:
–People whose houses have been destroyed by the cyclone or crops
have been destroyed by the flood can salvage things from their
homes and from their farms.
–Some family members have skills, which enable them to find
employment if they migrate, either temporarily or permanently

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Capacity
•Socio-economic Capacity:
–In most of the disasters, people suffer their greatest losses in the
physical and material realm.
–Rich people have the capacity to recover soon because of their
wealth.
–In fact, they are seldom hit by disasters because they live in safe
areas and their houses are built with stronger materials.
–However, even when everything is destroyed they have the capacity
to cope up with it.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Capacity
•Hazards are always prevalent, but the hazard becomes a disaster
only when there is greater vulnerability and less of capacity to cope
with it.
•In other words the frequency of likelihood of a hazard and the
vulnerability of the community increases the risk of being severely
affected.

Disaster and Development
•Disasters and development are closely linked in that disasters can
destroy development initiatives and create development
opportunitiesand that schemes can both increase and decrease
vulnerability.
•The prevailing attitude has been that natural disasters, were an act
of natureand as such were beyond human control; accepting death
and damage to property was part of the costs.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster and Development
•With such an attitude, most development plans were designed
without consideration for the effect disasters would have on
community plans and vice versa.
•When a disaster did occure, the response was directed at meeting
emergency needs and cleaning up.
•Now it is realisedthat much more can and need to be done to
reduce the severity of hazards and disasters.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster and Development
•Relationships between disasters and development
–Disasters set back development programming destroying years of
development initiatives and Infrastructure improvement.
•e.g. transport and utility systems are destroyed by a flood.

Keyur Nagecha

Disaster and Development
–Rebuilding after a disaster provides significant opportunities to
initiate development programs.
•After Bhuj, Gujarat earthquake 2001, considerable development has
taken place in the field of earthquake resistant design and construction.
•Almost all the multistoried buildings in zone-Ill and IV arc built with
earthquake resistant structures.
•IS codes on earthquake resistant design and construction have been
modified

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Disaster and Development
–Development programs can increase an area’s susceptibility to
disasters.
•A major increase in live stock development leads to overgrazing, which
contributes to desertification and increased vulnerability to famines.
–Development programs can be designed to decrease the
susceptibility to disasters and their negative consequences.
•Housing projects constructed under building codes designed to
withstand high winds result in less destruction during the next tropical
storms

Positive and Negative Effects of Disaster
•Positive Effects:
–Development can reduce vulnerability by increasing awareness and
by development mitigation and disaster preparedness.
–Disasters can provide development opportunities to the community
or the country.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Positive and Negative Effects of Disaster
•Negative Effects:
–Development can increase the vulnerability and can set back
development.
–Disasters can seriously disrupt development initiatives in several
ways, including loss of revenue, interruption of programs, impact on
investment climate, impact on non-formal sector and political
destabilization.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Positive and Negative Effects of Disaster
–Negative effects can be broadly described as.
–1. Loss of resources
–2. Impact on investment climate
–3. Political destabilization

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Positive and Negative Effects of Disaster
–1. Loss of resources:
•Disasters affect the development through impact on capital stock and
inventory, loss of production and provision of services, due to
disruption and increased cost of goods and services
•The secondary effects include inflation, problems of payment of
balances, increase in fiscal expenditure and decrease in monetary
reserves.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Positive and Negative Effects of Disaster
•The outcome of these losses of resources include :
–loss of economic growth
–delay in development programs
–cancellation of some development programs
–There may be a shift in skilled human resources towards high visibility
recovery activity -a diversion from long term to short term needs.
–Disasters interrupt the ongoing programs and divert the resources from
originally planned uses

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Positive and Negative Effects of Disaster
–2. Impact on Investment Climate:
•Disasters when occur at repeated short intervals have a negative impact
on investments, as the climate is not conducive to the investors who
seek stability and certainty and have no wish to risk their money.
•Loss of employment associated with disasters further depresses the
market demands, causes stagnation and limits overall growth.
•Disasters depresses the non-formal economy, through the direct costs
of lost equipmentsand housing and through indirect costs that include
lost employment and lost income

Keyur Nagecha
V. V. P. Engineering College: Rajkot
Positive and Negative Effects of Disaster
–3. Political Destabilization
•The stress caused by the disaster often results in destabilization of the
government, especially it has mismanaged the relief and recovery
operations.
•If it could not meet the expectations of the survivors, then the
discontent of the community may translate into some part of protest,
the government may be made a scapegoat for the problems beyond its
control, and it may lead to its downfall.
•It’s a common observation that the governments were either
overthrown or collapsed after a major disaster.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
How Development May Lead to Disasters?
•The side effects of well -meaning development efforts sometimes
have disastrous consequences.
•The development projects that are implemented without taking
into consideration the existing environmental hazards may actually
increase the vulnerability to natural disasters,

Keyur Nagecha
V. V. P. Engineering College: Rajkot
How Development May Lead to Disasters?
–e.g. projects designed to give more employment opportunities and
more income can lure people with low income to migrate to the
project area and thus increase the population density of the area,
forcing the migrants to seek housing in the areas that were previously
avoided such as on hillsides, or in flood plains and exposing them to
the risks of landslides or floods.
–The cost of relief assistance after a landslide of flood can easily
outweigh the benefits to the economy of more jobs.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
How Development May Lead to Disasters?
•Sometimes, development projects may lead to negative political
consequence that increase the vulnerability to civil conflicts.
•Some development projects commence without fully assessing
their impact on the environment, thus can give rise to increased
vulnerability to disasters,
–e.g. the post disaster reconstruction projects may increase the
demand for wood to fortify houses, which may result in massive
deforestation, which in turn bring increased vulnerability to mud
slides and may possibly cause long term environmental changes as
well

Keyur Nagecha
V. V. P. Engineering College: Rajkot
How Development May Lead to Disasters?
•Desertification due to drilling of wells in marginal areas, causes
population clustering around the wells.
•Loss of biological diversity due to deforestation and desertification
can also occur.
•Construction of hydro-electric dams leads to displacement of
people and salinization of soil.
•Irrigation schemes cause flooding where canals counter natural
water flow.

Keyur Nagecha
V. V. P. Engineering College: Rajkot
How Development May Lead to Disasters?
•Lack of soil and water management, centralization of planning
process can lead to watershed erosion and famines due to lack of
organization of local governments,
•Increase in pesticides or fertilizer use to augment crop yields, cause
contamination of potable water supplies.
•Construction of chemical plant or other industries generating
employment can lead to inadvertent release of chemicals or other
toxic effluents, contamination of water sources and supplies and
causing increased health problems or even deaths
