1.2.4. Environmental Vulnerability

So, hazard that may cause some kind of impact on human life and property does not only define the disaster, it also matter that how many people when they are exposed to that hazard. But that is not only enough, it also depends on what and what types of people, what are their characteristics, what are their features, who are exposed to that disaster, so to define disaster so, the question is why is so? We consider this is a vulnerability, that vulnerability is one of the critical conditions to define that the degree of disasters.

This chunk introduces the concept of vulnerability in relation to disasters. It emphasizes that a disaster is not solely defined by the hazard itself but also by the number and characteristics of people exposed to that hazard. Vulnerability is critical in understanding how disasters affect communities. It highlights that characteristics such as age, social status, and economic conditions contribute to how susceptible a community is to the impacts of a disaster.

Imagine a storm approaching a coastal town. A wealthy neighborhood might have stronger buildings and better emergency services, reducing their vulnerability to the storm. In contrast, a poorer area with flimsy houses and less access to resources may face more severe consequences. This illustrates how vulnerability varies among different communities.

Now, we define vulnerability as the condition, that determined by physical, social, economic and environmental factors or process which increase the susceptibility of a community to the impact of hazard.

This chunk defines vulnerability as being influenced by various factors. It explains that these factors can be physical (like the condition of buildings), social (like community structure and relationships), economic (like income levels and access to insurance), and environmental (like the state of natural resources). All these factors work together to increase the likelihood that a community will be severely impacted by disasters.

Think of a village located near a river. If the river floods, the physical vulnerability (poorly built homes), social vulnerability (an aging population), and economic vulnerability (lack of insurance) can compound the effects of the flood, leading to greater disaster impacts.

We have the social vulnerability like coping ability, resistance or resilience or we could have some social empowerment like age, gender, ethnicity, household type as I said that younger people are when a society is comprising only by elder people, the society is considered to be more vulnerable than when there are younger people also.

This chunk discusses social factors contributing to vulnerability. It points out that characteristics such as age, gender, and ethnicity can affect how vulnerable a population is to disasters. For instance, communities dominated by older generations may struggle more in emergencies compared to mixed-age communities. Additionally, women may face specific risks due to limited opportunities compared to men, especially in patriarchal societies.

Consider a community facing a natural disaster: younger people may be more mobile and adaptable, while older individuals may struggle to evacuate quickly. Recognizing these social dynamics can help in planning more effective response strategies.

We have to also consider the economic environment or economic factors of vulnerability. One is the income and assets and insurance and debts. How much the person's income has, not only income, but also if they have insurance like if someone has flood insurance so if they are affected, and how they will be impacted by the flood, it depends on insurance.

This chunk elaborates on economic factors that contribute to vulnerability. It explains that income levels, assets, availability of insurance, and debts can significantly affect how a community withstands a disaster. For example, individuals without insurance may have a much harder time recovering from a flood since they can't afford to repair their homes or replace lost belongings. Conversely, those with adequate insurance coverage are generally more resilient.

Imagine two families affected by the same hurricane. One family has comprehensive insurance and enough savings to recover quickly, while the other does not have insurance and lives paycheck to paycheck. The second family will suffer much more due to the financial strain of rebuilding their lives after the disaster.

But this is just for as a reference; we can have also physical factors of disaster vulnerability. Like, the land use and this mainly came from land use and engineering architectural perspective to define the physical vulnerability of disaster and also like the which locations the building are there, what are their conditions so, these all defined the buildings of vulnerability.

This chunk discusses the physical factors that determine vulnerability. It highlights how the location of buildings, the materials used, and the engineering standards applied during construction can influence a community's resilience to disasters. For instance, buildings in flood-prone areas that are not designed to withstand water damage are more physically vulnerable.

Think of two neighborhoods: one built on high ground with sturdy homes designed to resist flooding, and one in a low-lying area with poorly constructed houses. The latter neighborhood will likely suffer greater damage in a flood, illustrating the importance of physical vulnerability in disaster scenarios.

Also, we have environmental factors like the extent of natural resource depletions, the state of resource degradations, exposure to toxic and hazardous pollutants.

In this chunk, environmental factors that influence vulnerability are discussed. It includes the depletion of natural resources, degradation of the environment, and exposure to pollutants. These factors can weaken a community's ability to cope with disasters by affecting health and the ability to recover from stressors.

Consider a community that relies on a polluted river for drinking water. In the event of a disaster, they may already have weakened health due to toxins, making them more vulnerable to the impacts of that disaster, such as a flood or industrial accident.

So, hazard, exposure and vulnerability these 3 components are important to understand disaster risk.

This chunk outlines the three critical components of disaster risk: hazard, exposure, and vulnerability. Understanding all three is essential for assessing how a disaster might affect a community. Hazard refers to the potential event (like a flood); exposure involves people and assets at risk, while vulnerability indicates how susceptible those who are exposed are to harm.

Think of it like a recipe for disaster: you need all three ingredients. If there’s no hazard (like a flood), it doesn’t matter who is exposed or how vulnerable they are. Understanding and preparing for the potential consequences of these three factors can help communities reduce their disaster risk.

But, here is the definition of disaster that is hazard, exposure and vulnerability; that is defining the disaster. And it is a formal definition given by United Nations, ISDR as disaster is a function of the risk process, it results from the combination of hazards, condition of vulnerability and insufficient capacity or measures to reduce the potential negative consequence of risk.

This final chunk presents a formal definition of disaster as provided by the United Nations. It defines a disaster as occurring when hazards, exposure, and vulnerability combine with an insufficient capacity to deal with the consequences. It emphasizes that disasters are serious disruptions that exceed a community's ability to cope with challenges using available resources.

Consider a town hit by an earthquake: if the buildings are poorly constructed (vulnerability), if there’s a high level of exposure (many people living there), and if there are no emergency services to help (insufficient capacity), the town faces a disaster. Understanding this definition helps communities prepare better for potential disasters.
