Definition of Vulnerability
Unlock Audio Lesson
Today we’re going to discuss vulnerability. Can someone explain what we might mean by vulnerability in the context of disasters?
Isn't it how likely a person is to be harmed by a disaster?
Exactly! Vulnerability refers to conditions that increase a community's susceptibility to hazards. It’s influenced by factors such as social, economic, physical, and environmental aspects.
So all these factors work together?
Yes, they do. For example, someone living in a well-built house in a safer area might be less vulnerable than someone in a poorly constructed home in a flood-prone region. Remember: 'SAFE' stands for 'Structural and Economic factors' that contribute to safety.
Social Vulnerability Factors

Now let’s delve deeper into social vulnerability. Who can share some factors that might impact social vulnerability?
Age and gender can make a difference, right?
Absolutely! For instance, elderly individuals often have less mobility and resources during disasters. And women frequently face socio-economic challenges that can increase their vulnerability.
What about ethnic backgrounds? Is that a factor too?
Yes, ethnicity plays a key role. Minority ethnic communities often face higher vulnerability due to less access to resources, which can enhance their exposure during disasters. Let's remember 'AGE' – 'Access, Gender, Ethnicity'.
Economic Vulnerability
Unlock Audio Lesson
Let's switch gears and talk about economic vulnerability. What do you think are some economic factors that can influence disaster risk?
Income and insurance are probably very important?
Correct! Individuals with higher incomes and insurance coverage are typically better able to recover from disasters. Additionally, debts can limit recovery options. This reminds us that 'PARS'—'Poverty, Assets, Resilience, and Security'—are vital aspects in assessing vulnerability.
That makes sense! If someone has a lot of debts, they might not be able to bounce back as easily.
Physical and Environmental Factors
Unlock Audio Lesson
Now, let’s discuss physical vulnerability. What are some physical factors that impact how vulnerable a community is to hazards?
I think where buildings are located and how they're constructed definitely matter.
Exactly! Land use, density of the population, and building materials significantly affect vulnerability. If a community is in a high-risk area, like a floodplain, they face greater risks unless preventive measures are in place. Remember 'MAPS': 'Materials, Area, Population, Safety'.
Oh! And if people are already unhealthy or lack education, it can worsen their situation.
Introduction & Overview
Read a summary of the section's main ideas. Choose from Basic, Medium, or Detailed.
Quick Overview
Standard
Social vulnerability is defined as the condition determined by various factors that increase a community’s susceptibility to hazards. Characteristics such as age, gender, ethnicity, economic status, and environmental conditions are crucial in understanding the extent of vulnerability, thereby affecting disaster risk and resilience.
Detailed
In this section, social vulnerability is identified as a critical component to define disaster risk, which stems from exposure to hazards and personal or community characteristics. Vulnerability encompasses not only the physical risk of being exposed to hazards, but also socio-economic factors, such as income, education, and social networks, which contribute to the ability to cope with and recover from disasters. Communities can exhibit varying degrees of vulnerability based on demographics, including age and gender, with the elderly and women often facing higher levels of risk due to limited socio-economic opportunities. Furthermore, aspects like household structures, financial security, access to resources, and community resilience play vital roles in understanding social vulnerability. The interconnectedness of different forms of vulnerability—social, economic, physical, and environmental—highlights the complex nature of disaster risk, reinforcing the need for targeted adaptation strategies and capacity-building measures.

We define vulnerability as the condition determined by physical, social, economic and environmental factors or processes which increase the susceptibility of a community to the impact of hazard.
Detailed Explanation
Vulnerability refers to how likely a community is to suffer from the effects of a hazard. This susceptibility is influenced by various factors — physical (like building quality), social (like community support), economic (like income levels), and environmental (like location of the community). Essentially, vulnerability outlines why some communities are more affected by disasters than others.
Examples & Analogies
Imagine a small village located near a river. If the village has strong houses and good community support, they are less vulnerable to floods than a nearby village with weak houses and little social cohesion. Thus, vulnerability is like a safety net — the more threads you have woven together (support systems), the safer you are from falling into a disaster.

Which geographical region, socio-economic class etc., who are the vulnerable people like which kind of households or individuals are and what should be done.
Detailed Explanation
Vulnerability is shaped by various factors such as geographical region, socio-economic class, and the characteristics of individuals or households. For instance, poorer areas often have less infrastructure to withstand disasters, making their residents more vulnerable. The specific needs and capacities of vulnerable groups also dictate what measures can be taken to improve their resilience.
Examples & Analogies
Think about a community living in a coastal area prone to hurricanes. Wealthier households may have the means to fortify their homes or evacuate, while less affluent households may lack resources, making them more vulnerable. This situation highlights how socio-economic factors directly impact a community's ability to cope with disaster.
Social Factors of Vulnerability

We have the social vulnerability like, coping ability, resistance or resilience. Younger people are when a society is comprising only elder people, it is considered to be more vulnerable.
Detailed Explanation
Social factors include the ability of individuals and communities to cope and recover from disasters, commonly referred to as resilience. Characteristics such as age, gender, and social structures play significant roles. For example, a society with a higher proportion of elderly individuals may struggle more during a disaster due to lower mobility and health issues, making it more vulnerable.
Examples & Analogies
Consider a neighborhood where most residents are elderly. In the event of a natural disaster like a flood, these individuals might have more difficulties evacuating quickly compared to younger, more mobile populations. This gap in resilience illustrates how age-related vulnerabilities can shape community responses to hazards.
Economic Factors of Vulnerability

We have economic factors like economic status of individual, community, and society and income, income reserves, debts, access to credits, loans, insurance.
Detailed Explanation
Economic factors significantly influence vulnerability, with elements such as income, debts, and insurance coverage determining a community's ability to withstand disasters. Those with higher incomes and insurance are often more capable of recovery because they have resources to draw upon during crises.
Examples & Analogies
Imagine two families affected by a flood. One family has adequate insurance coverage and savings, allowing them to rebuild their home quickly. The other family, however, has no savings or insurance and struggles to recover. This difference in financial resources shows how crucial economic factors are in defining vulnerability.
Environmental Factors of Vulnerability

Also, we have environmental factors like the extent of natural resource depletion, the state of resource degradation, exposure to toxic and hazardous pollutants.
Detailed Explanation
Environmental factors include how degradation of natural resources and exposure to pollutants increase vulnerability. Communities reliant on degraded environments are at higher risk during disasters since their natural resilience is compromised.
Examples & Analogies
Think of a community living near an industrial area with polluted air and water. This community might be already facing health issues due to pollution, making them even more vulnerable when a disaster strikes, such as an earthquake or flood. The existing environmental stress heightens their susceptibility to the impacts of that disaster.
