Editor's Notes
- Hazard a danger or risk.
- EXPOSURE the state of being exposed to contact with something.
- VULNERABILITY the quality or state of being exposed to the possibility of being attacked or harmed, either physically or emotionally.
- DISRUPTION disturbance or problems which interrupt an event, activity, or process.
- Environment EENNVIROTM METRONEVINN the surroundings or conditions in which a person, animal, or plant lives or operates
- DEFENSELESS SSSEEEEDNL without defense or protection; totally vulnerable.
- WEAKNESS EEASSNWK the quality or state of being weak
- What is the Difference between a threat, a vulnerability, and a risks?
- 1. Who do you think is more vulnerable? Thomas or Maria? Why? 2. what were the actions taken by thomast that made him less vulnerable to flood? 3. What have you realized from their story?
- 1. Who do you think is more vulnerable? Thomas or Maria? Why? 2. what were the actions taken by thomast that made him less vulnerable to flood? 3. What have you realized from their story?
- recognizing the vulnerabilities help the community to formulate strategies, programs, and prevention, mitigation and immediate response incase disasters might happen.
- let us define first what is vulnerability. we always encounter this word "vulnerable" but do you really understand the meaning of this? vulnerability is a degree of susceptibility and resilience of community and environment to hazard. this means the inability to withstand the effects of disaster. there is a big chance that you will be affected from something. your prone. this means the inability to withstand the effects of disaster. there is a big chance that you will be affected from something. your prone.
- example is the senior citizen are vulnerable to covid 19. so what it means? does it mean that the senior citizens are more prone to diseases? why are they prone? it is because of their characteristics one factor of vulnerability is the word susceptibility and resilience
- when we say susceptible it means easily influenced or harmed by something. ask students: madali ka bang naapektuhan ng mga bagay bagay sa paligid mo? does your body can get diseases easily? that is susceptible.
- second is the word resilience this is your capacity to recover quickly from the difficulties. how quickly we can recover? what is our capacity of recovering from certain event. and that is our resilient.
- Vulnerability - As vulnerability increases, it means that the population is at greater risk of suffering from a severe natural danger. To lessen vulnerability means to make the community prepared and ready for the possible damaging effect of the hazard.
- Exposure Liability Susceptibility weakness Defenseless Possibility of being attacked or harmed
- Direction: Spot the hazard. (hazard is threat which will have a negative effect on humans) **Give at least three (3) potential scenarios from each picture that can occur due to the presence of hazard? Exposed cable wires Breaker Sink and socket Talking to someone while walking Plant on desk Screw and socket Fire extinguisher Coffee beside her monitor
- now let us identify the vulnerability of different elements that are exposed to different or specific hazard
- 1. physical vulnerability when something is physical, it is really there. you can see it, touch it, taste it, hear it, or even smell it.
- for physical vulnerability it includes population density levels, Place or settlement, site design, materials used for infrastructure and housing.
- So what do we call population density? let say for example. in a certain area of land. We have family A that has 17 members. then in family b they have 3 family members. we can say that family A is more dense than family B in This is a given area where there are differences in the number of population. And that is population density.
- Example: when UP visayas was totally destroyed by yolanda. The infrastructure was totally damaged. Next is the decrease of population like what happened in baguio during the 1990 killer earthquake. in north luzon where 1,621 dead 3,513 injured 321 missing 126,035 displaced
- 2nd is social vulnerability, which refer to potential negative effects of the community, it happens due to inability of people, organization and societies to prevent severe effects from hazards because of the expected behavior in social interactions institutions system of cultural values.
- for example the line of communication was cut off when communication company shut down, and disruption of transportation system due to flooded area, fallen trees, broken roads and bridges.
- with some difficulties in the delivery of services like relief goods and medicines. a lot of problems occurs like shortage of food and spread of infectious diseases Therefore when social elements are exposed to hazards this may lead to disruption of normal processes and activities. in a community.
- Example: Covid-19 pandemic wherein the most affected are those who belong to low income and informal workers. Therefore, the poorer the country, the more vulnerable to disasters because they lack the funds or budget. the most affected are those who are Low income and Informal Workers and greatly affected.
- All living organisms are dependent on the environment for survival. Therefore, Human activities like deforestation, burning of fossil fuels, and kaingin affect the natural abilities of the environment to protect itself from any natural hazard due to absence of trees which may cause landslide and flash floods it affects the natural abilities of the environment to protect itself if an natural hazard occurs
- Direction: Spot the hazard. (hazard is threat which will have a negative effect on humans) **Give at least three (3) potential scenarios from each picture that can occur due to the presence of hazard? Trash bin Fire extinguisher Exposed cable wires Opened drawers book shelf Boxes Man walking with books Kettle Ladders Chairs Floors Blocked fire exit
- Vulnerability can be expressed as: 0 = lowest degree of vulnerability and 1 as the highest degree.
- Answer: Social Physical Physical Economic Environmental
- What is the hazard shown in the picture? Which area is exposed to hazard? What do you think is the cause of this incident? Which part in the presented image will be least likely affected?
- Exposure to hazard can make a community vulnerable. But not all communities that are exposed to hazard can be considered vulnerable. Vulnerability depends on the preparedness and readiness to a hazard of the community. Mitigation (a process or the result of making something less severe/ dangerous) - that is how maria planned the situation
- Mitigation is the action of reducing something's severity, seriousness, or painfulness.
