Matter of Concern Disaster-related mortality risk is lower in high development
countries than in low development countries. Inappropriate development is responsible for configuring
disaster risk .

Other Disasters• A human stampede at the temple of Naina Devi
occurred on 3 August 2008. 162 people died.• Punjab governor Surendra Nath and nine
members of his family were killed when the government's Super-King aircraft crashed into high mountains in bad weather on July 9, 1994 in Himachal Pradesh.

ATTITUDE &understanding
• THEORY OF FURY OF GOD• THEORY OF FURY OF NATURE• SCIENTIFIC THEORY
Key Elements of a Disaster
D=(H+R)*V-C• Disaster result from the combination of hazards, conditions
of vulnerability and insufficient capacity or measures to reduce the potential negative consequences of risk.
04/10/23
Hazard• A dangerous
phenomenon, substance, human activity or condition that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage.
04/10/23
Vulnerability
• The characteristics and circumstances of a community, system or asset that make it susceptible to the damaging effects of a hazard.

Capturing dimensions of vulnerability and capacity
•The conditions determined by the physical, social, economic and environmental factors or processes which increase the susceptibility of a community to the impact of hazards/development related risks.
04/10/23
Capacity• The combination
of all the strengths, attributes and resources available within a community, society or organization that can be used to achieve agreed goals.
04/10/23
Risk• Risk is the probability of
harmful consequences, or expected losses (deaths, injuries, disruption to livelihoods and economic activity, and damage to property or the environment) resulting from interactions between natural or human-induced hazards and vulnerable conditions.
• Conventionally risk is expressed by the notation:
Risk = (H X V) / C
Risk = f (Hazard, Exposure, Vulnerability, Location).
HAZARD- occurrence of an earthquake of sufficient Magnitude (hence: Intensity at the epicenter) capable of causing damage to the man-made structures.
EXPOSURE- Objects and structures built by man which are exposed to the effects of the `hazard‘: buildings, bridges, dams, power plant, life-line structure, etc.
VULNERABILITY-Damageability of the `exposure' under the action of the hazard; weaker ones being more vulnerable and `risky' than the stronger ones.
LOCATION- (i) How far the `exposure' is situated from the Hazard location the nearer ones being in greater danger than those far away, and
(ii) Local site conditions which can modify the hazard and/or affect the stability of the exposure, such as topography, soil deposit, water table, etc.

Resilience
• Ability to absorb change
• Ability + Self organizing
• Ability to Re-organize
Source: CCR Handbook
Resilience is the ability to withstand damage or to recover quickly from a shock such as a disaster. A high level of resilience allows people, systems and environments to recover quickly, therefore reducing the negative impact of a shock.
04/10/23
Resilience (2)SWARM THEORY
ALLIGNMENT
COHESION
SEPERATION
SWARM: On a system level, a swarm is hardly vulnerable
System Properties:• High Degree of Redundancy (Individuals)• Flexibility/Robustness• Adaptive Behavior• Responsiveness/Reorganization
Organizational Properties:• Decentralized (no central command)• Systems behavior is emergent
Slide Ref: William Veerbeek, VIRUS and SOUP
When does a HAZARD lead to a Disaster ?
The DM Act, 2005
“Disaster” means a catastrophe , mishap, calamity or grave occurrence in any area , arising from natural or manmade 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 nature or magnitude to be beyond the coping capacity of the community of the affected areas;
04/10/23
Disaster• A serious disruption
of the functioning of a community or a society involving widespread human, material, economic or environmental losses and impacts, which exceeds the ability of the affected community or society to cope using its own resources.
04/10/23
The Climate Change Problem:
The report also confirms that the current atmospheric concentration of Carbon dioxide and Methane, the two important heat-trapping gases, "exceeds by far the natural range over the last 6,50,000 years."
International Panel on Climate Change (IPCC) Fourth Assessment 2007 Report concludes that the Global Warming is Unequivocal, and that the earth's climate is warming.

Climate Change Adaptation• refers to actions taken to limit the
negative impact of climate change on human systems.
• This can be defined as “initiatives and measures to reduce the vulnerability of natural and human systems against actual or expected climate change effects” (IPCC, 2007b).
• This includes actions taken to limit the impacts of both the slow trends associated with climate change, such as sea level rise or less predictable rainfall, and adaptation to increased frequency and magnitude of climatic hazards.
GENESIS Contd.,
EARLIER CONCEPT – Reactive 4 R
RescueRecoveryReliefRehabilitation
PRESENT CONCEPT - ProactivePlanningPreventionPreparednessResponse
Crunch model1. Disaster happens only when a hazard affects vulnerable people
and these two elements come together.2. A natural phenomenon by itself is not a disaster; 3. Population maybe vulnerable for many years, yet without the
“trigger event”, there is no disaster.4. Vulnerability - a pressure that is rooted in socio-economic and
political processes - is built up and has to be addressed, or released, to reduce the risk of a disaster. These processes may include poverty, age-related discrimination, exclusion or exploitation based on gender, ethnic or religious factors. The outcome will be “safe” as opposed to “unsafe conditions”,
5. Resilient or capable communities” as opposed to “vulnerable communities” and “sustainable livelihoods” as opposed to “unsustainable livelihoods”.
• For example, for people living by a river prone to sudden onset flooding:
• • “unsafe conditions” may be: poor housing conditions, dangerous location, risky livelihoods, lack of disaster preparedness skills, etc.
• • “dynamic pressures” may be: no community organization for collective efforts to reduce flood risks, rapid migration tendencies that change the social structure, the lack of local markets for small farmers to sell their produces or buy agricultural inputs, etc.
• • “root causes” may be: government negligence of sand mining in that river, the lack of government policy on flood warning systems and land use planning, poor men and women are not allowed to attend meetings on flood mitigation and emergency response preparedness, etc.
