4. "The man does better who
runs from disaster than
he who is caught by it"

5. Factors affecting Vulnerabilities
01

6. Causes of Vulnerability:
 Poverty
 Population growth
 Rapid urbanization
 Transitions in cultural practices
 Environmental degradation
 Lack of awareness and information
 Wars and civil strife

7. Characteristics of Vulnerability:
 Multi-dimensional
 Dynamic
 Scale-dependent
 Site-specific

9.  Wealth is one of the most important human factors in vulnerability.
 Wealth affects vulnerability in several ways:
1. The poor are less able to afford housing and other infrastructure that can withstand extreme events.
2. They are less able to purchase resources needed for disaster response and are less likely to have
insurance policies that can contribute.
3. They are also less likely to have access to medical care.
Wealth

10. But there are exceptions. For example,
 some coastal areas contain expensive beachside real estate populated mainly by the rich, leaving the rich
more vulnerable to tsunamis, storm surges, and other coastal hazards.
 Also, the rich tend to lose more money from disasters, simply because they have more valuable property at
stake.
 Eg. Hurricane Katrina (wealthier area, fewer deaths, higher monetary damage); Cyclone Nargis (poorer
area, more deaths, less monetary damage).

11. Education
 Education is another important factor in hazard impacts.
 With education, we can learn how to avoid or reduce many impacts.
 When populations are literate, then written messages can be used to spread word about
hazards in general or about specific disasters.
 Even without literacy, it is possible to educate a population about hazards in order to help it
reduce its vulnerability.
 When populations include professionals trained in hazards, then these people can help the
populations with their hazards preparations and responses.

12. Governance
 The nature of both formal governments and informal governance in a population is another important
factor.
 Governments can advance policies that reduce vulnerability.
 They can establish agencies tasked with reducing vulnerability, such as NDMA.
 They can support education and awareness efforts, as well as economic development to reduce poverty.
 Finally, they can foster social networks and empower individuals and communities to help themselves to
prepare for and respond to hazards.
 Likewise, even without governments, communities can informally engage in many of these governance
activities. Often the most vulnerable people are those who are politically marginalized, because these people
have less access to key resources and opportunities

13.  Eg. Myanmar government during Cyclone Nargis. This government is isolated from the international
community and, thus, was not welcoming to international assistance in the aftermath of the cyclone.
 Haiti after its 2010 earthquake. Haiti, like Myanmar, is a poor country, but it has positive and close
relationships with the international community and thus readily welcomed international assistance in the
aftermath of the earthquake. This assistance saved many lives and is helping Haiti rebuild.

14. Technology
 The capabilities of the available technology can also play a large role in disasters.
 Technology can improve our ability to forecast extreme events, withstand the impacts of the events, and
recover afterwards.
Technology is closely tied to wealth, education, and governance.
 Wealthier, more educated society's are more likely to have more advanced technology.
 A society's governance systems play a large role in how - and how effectively - the available technology is
used in a disaster situation.
 Eg. All the preparations for facing the disaster and response activities in Disaster.

15. Age
 Children and the elderly tend to be more vulnerable.
 They have less physical strength to survive disasters and are often more susceptible to certain diseases.
 The elderly often also have declining vision and hearing.
 Children, especially young children, have less education.
 Finally, both children and the elderly have fewer financial resources and are frequently dependent on
others for survival.
 In order for them to survive a disaster, it is necessary for both them and their caretakers to stay alive
and stay together.
 Eg. 2003 European heat wave. About 40,000 people died in one of the hottest summers ever in Europe.
Many of the deaths were elderly people who were still capable of taking care of themselves. These people
were not able to adapt to the extreme heat and had no one helping them out.

16. Gender
 Women are often more vulnerable to natural hazards than men.
 This is in part because women are more likely to be poor, less educated, and politically marginalized.
 Women often face additional burdens as caretakers of families.
 When disaster strikes, women are often the ones tasked with protecting children and the elderly.
 This leaves them less mobile and more likely to experience harm themselves.

17. Vulnerability relates to a number of factors, including (Types):

18. Differential impacts of disaster

19. Impact of disaster could be
 Impact on Human Life
 Impact on Economy
 Impact on Ecology and Environment
 Psychological Impacts
 Social Impacts & Health Impacts

20. Impact on Human Life
 No activity of loss and damage can be termed as disaster unless it has a direct impact on humans.
 The most fragile community on earth is man kind which is susceptible to all kinds of danger and hazards.
To off set and reduce the impact of these hazards, humans are evolving themselves.
 Any loss whether it is of human life or of livestock, its loss of property it has direct bearing on humans.
Man is a social animal and can not live alone. Small groups joined together to form communities and
communities grew to form cosmopolitan cities.
 Some of the impacts on human life can further be listed as follow:-

21.  Loss of Human Life. The worst damage of a disaster is the loss of human life. All the property and
house holds can be recouped with passage of time or with assistance of other communities / donors but
life is such a precious thing that its replacement cannot be done. The loosing of a family member has far
more lasting bad memories and impacts as compare to any other loss. This leads to social and
psychological issues that affect the recovery phase and lengthens the rehabilitation phase.
 Loss of Livelihood including Households and Property. One of the immediate impact indicators that
define the severity of a disaster is the loss of livelihoods of the inhabitants. The earnings of whole life is
just washed away in few moments and it affects badly on recovery phase too.

22.  Displacement. Result of a disaster could be the temporary or permanent displacement from the
affected area to a new location where environment (socially and economically) are not so favorable.
Education. Disaster means the complete destruction of not only personal life routine but it al so affect
on the education badly. Either schools are destructed or if not, these are used to house displaced people.
In any case, continuity of education is not there.

23. Impact on Economy

24. Impact on Ecology and Environment

25. Psychological impact

26. Social impacts

27. Health impacts

28. Impacts of development projects

29. DAMS
Dams provide a means of regulating downstream surface water flows over space and time by altering
the natural spatial and temporal distributions of stream flows.
What is the function of Dams:

30. Purpose of Dams
To improve the quality of human life by providing……

34. Environmental Impacts 0f Dams
 Terrestrial Ecosystems and Biodiversity
 Greenhouse Gas Emissions
 Downstream Aquatic Ecosystems and Biodiversity
 Impacts of changes in flow regimes
 Impacts of trapping sediments and nutrients behind a dam
 Blocking migration of aquatic organisms

35. Non Reciprocal Effects of Dams on Society
 Hydropower
 Irrigation, Drainage & Flood control
 Displacement of People and Livelihoods
 Downstream Livelihoods
 Cultural Heritage
 Under-counting of the displaced
 Physically displaced populations enumerated but not resettled
 Socio-economic Impacts through the Planning and Project Cycle

36. Dam Failure
Adaptation to Climate Change

37. Adaptation to Climate Change

38. What is the problem?
 What is climate change?
 Climate change and its relation to disaster
 Climate change, vulnerability, adaptation
 Community based adaptation (CBA)
- CBA and Flood
- CBA and Drought
- Success of CBA
 Climate change and policy
- National
- Local
- International

39. What is the problem?
 People are observing new trends in disaster impacts
 Traditional weather prediction does not work
 Traditional disaster planning and policy are not working
 New development activities are going on, without further consideration of future climatic scenario
 Thus, there is a lack of:
- Proper perception on climate change
- Proper understanding and correlation
- Proper inter-linkages, and
- Appropriate Actions

40.  Due to increasing human activities at different levels, prominent changes occur in the climate and natural
environment
 Climate change is already happening:
- The global mean surface temperature in the 20th century has risen by about 0,6 °C.
 Climate change is also projected:
- The average sea level is projected to rise by between 0.09 and 0.88 m
- The global mean surface temperature is projected to increase by 1.4-5.8°C by 2100
 Climate change projections face some crucial issues:
- The projections are often very coarse, and lack local details
- The projections are often far into future, not immediate future
- Better in predicting average change than extreme climatic conditions
What is Climate Change?

41. Climate Change and Disasters
 Climate change will have a variety of impacts in terms of natural disasters:
- More droughts, floods, heat waves, water shortages,
- Increasingly diversion of the typhoon path
 Impacts will hit the poor hardest
 Precautionary principle
- Climate Change impacts is multiplied with misguided development

42. Climate Change and Vulnerability
 Climate change impacts are related to vulnerability of different types: social, cultural, economic etc.
 Important issues are: where are the vulnerable areas, and who are the most vulnerable
 Climate change impacts should be seen at different levels (like international, national and local), and
at different issues (like eco-system, settlements, food, health and water)
 Climate change impact and capacity assessment
 Climate change vulnerability can be assessed in different ways: through stakeholder, resource
mapping, and sustainable livelihood analysis

43. What is Climate Change Adaptation?
 Implementation of climate change mitigation measures needs time
 Applicability of climate change adaptation is increasingly recognized
 Focus needs to be on community based adaptation, and local government policy options
 A few steps on climate change adaptation include: 1) preliminary climate risk assessment, 2) assess
priorities and plan follow-up, 3) raise awareness, 4) establish and enhance partnership, 5) highlight climate
related vulnerability with other actors, 6) document and share experiences, and 7) promote advocacy for
adaptive actions.

44.  Community based adaptation is getting increasing attention.
 Adaptation responses to date have been largely reactive rather than proactive.
 Proactive Micro-Adaptation (PMA) has a significant potential to be a crucial component of strategies
to address impacts of climate change.
 Further, proactive adaptation has considerable policy potential at various levels.
What is Community Based Adaptation?

45. Climate Change Adaptation Model

46. How CBA can be practiced? Coastal Zone
 Climate change has affected the coastal zone of the Philippines
 The worst sufferers are the fishing communities, due to change in the coastal eco-system
 Adaptation measures include local government policies, awareness raising among different
sectors, and national government strategies and policies

47. How CBA can be practiced? Drought
 A significant change of rainfall pattern is observed in Western India, resulting 2-3 consecutive drought
years
 The worst effect is on livelihoods: agriculture, and animal husbandry
 To cope with 3 consecutive years of drought is beyond community coping capacities
 Tradition drought proofing needs consideration of climate change uncertainties
 Collective efforts are being undertaken for drought proofing
 These measures, while implemented at community level, should be part of the local development policies

48. How CBA can be practiced? Flood
 Central Vietnam is experiencing large floods, often resulted due to catastrophic rain or rain due to
sudden typhoon.
 Agriculture, related livelihood options are deeply affected
 In rural areas, the adaptation measures are more on participatory planning, awareness raising, and
implementation.
 In urban areas, CBA is more related to urban planning, local development planning and policy, and
establishing effective communication system.

49.  Providing right climate information to farmers is one of key issue
 A few steps are:
- Providing climate outlook
- Transferring global to local outlook
- Translating climate outlook to local scenario
- Communication to local farmers
How CBA can be practiced? Climate Information

50.  The key issue of climate change community-based adaptation is the right information to the community
 Involvement of the community in the process is critical, and is linked to the ownership of the adaptation
actions
 Institutionalization at local government development plan is a definite challenge
 Coordination among NGO, local government, and academic is crucial
 High demand for training/awareness raising activities among stakeholders
Issues of Community Based Adaptation

51. Climate Change Adaptation: local
Incorporate the recommended actions into local government policies
Special emphasis should be given on agriculture and livelihood support system, and health and education
services in the local governments
Training and awareness raising of local government managers is one of the important aspect of the policy
measures
Resource commitment at local government is the key issue for the success of its adaptation actions
Multi-stakeholder cooperation is required at local level

52.  National and international policies set the context for facilitating Proactive micro adaptation (or
community based adaptation).
 Good policy coordination on a range of proactive adaptation measures and actions at various levels can
help avoid mal-adaptation.
 Resource mobilization is essential.
 Climate change impacts are cross-cutting in nature, and require synergies.
Climate Change Adaptation : National

53. Climate Change Adaptation: International
International climate negotiations to date, however, have paid inadequate attention to community based
climate change adaptation
Bilateral and multilateral development agency should have policy on climate change adaptation
Actions needs to be taken at international levels should have following emphasis:
- Efforts to link with other international initiatives
- Emphasis on near future scenario
- Risk management approach

54. Impacts of land use and land cover changes
on disaster risk

57. LAND USE: “Land use is characterized by the arrangements, activities and inputs people
undertake in a certain land cover type to produce, change or maintain it”
LAND COVER: land cover is the physical material at the surface of the earth. Land cover
include grass, asphalt, trees, bare ground, water etc.

58. ZONING: Zoning is the term used for designating permitted uses of certain parcels of
land by local governments.
 Generally, in urban areas, zoning will be divided five major categories: residential,
mixed residential-commercial, commercial, industrial, and special (e.g., power plants,
sports complexes, airports, shopping malls etc.).

60. NEED OF LAND USE ASSESSMENT
 Land use information can be used to develop solutions for natural resource
management issues such as salinity and water quality.
 More recent significant effects of land use include urban sprawl, soil erosion, soil
degradation, salinization and desertification.
The land use/land cover pattern of a region is an outcome of natural and socio –
economic factors and their utilization by man in time and space.
Information about land use change is necessary to update land cover maps and for
effective management and planning of the resources for sustainable development
(Alphan 2003).

61. Urban areas are changing due to various human activities, natural conditions and
developmental activities. According to the user requirements, updating of land
use maps are required to various departments and hence information of land
use/land cover in the form of maps and statistical data are very vital for spatial
planning, management and proper utilization of land.

66. The most serious threat observed is the occupation of hill slopes at an enormous phase
posing serious environmental impact in the form of destruction of the natural slope
morphology including natural drainage, soil cover, slope vegetation and slope stability.
The possible impacts include the depletion of groundwater, water logging in low laying
areas, gradual collapse of hill slopes resulting loss of human life and property. If this
continuous the natural land scape which is considered as most beautiful in this city, will be lost
forever
PROBLEMS FACED BY VISAKHAPATNAM

67.  The decrease in vegetation cover and forest cover may be an aspect of serious concern
and the planners and policy makers need to take necessary steps for conserving forest
cover.
The beach and coastal erosion by man made reasons should be closely monitored and
necessary scientific steps must be taken to stop the beach erosion to avoid further
environmental complications.
 In ordered to prevent inappropriate construction of building, the building code should be
strictly implemented
 Addressing the requirements after the flood has receded.
 There should be a proper land use control and settlement policy in the state
 Degradation of environment, disasters and poverty form a vicious cycle and this cycle can
be overcome only by a careful environment management planning and integrating it with
disaster management and poverty alleviation.
 There should be a proper land use control and settlement policy in the state

89. Indigenous Knowledge for Disaster Risk Reduction

91. These characteristics of coastal zone Indigenous Knowledge included the following:
 Relates to the water/ocean, its behavior as well as wind/weather conditions
 Characteristic of social system, generally smaller, close-knit communities
 Use of local materials (sand, thatch)
 Involvement of ecological elements (mangroves, coral reefs, rocky shores)
 Disseminated in small family groupings
 Closely related to fishing and farming practices - livelihood of inhabitants
Coastal Region

92. River Basin Management

93. Water Resource Management
The basic principles of Indigenous Knowledge relating to water resource management include:
1. Diversity: fulfilling the needs of local people/ adapted to local culture, climate, environment,
geography, etc.
2. Equality: common property, resource sharing, interest balancing
3. Environmentally friendly: multiple purpose, reuse, conservation
4. Economically sustainable: local materials, no need of extra energy for water transferring (use
of gravity)
