Q.Vulnerability is an essential element for defining disaster impacts and its threat to people. How and in what ways can vulnerability to disasters be characterized? Discuss different types of vulnerability with reference to disasters.

Body Analysis

Characterizing Vulnerability

To implement effective disaster risk reduction measures, decision-makers must understand where and how vulnerability exists. This characterization typically relies on two primary approaches:

• Scientific Approach: Focuses on the quantitative measurement, research, and empirical assessment of vulnerability and disaster risk.
• Policy Approach: Translates vulnerability data into spatial distributions and actionable frameworks to guide administrative interventions.

Types of Vulnerability with Reference to Disasters

• Geographical Vulnerability: Determined by physical location. Areas situated along coastlines, riverbanks, or active seismic zones are inherently more exposed to hazards.
  • Example: Coastal regions are highly susceptible to cyclones and tsunamis, whereas the Himalayan foothills face severe earthquake and landslide risks.
• Economic Vulnerability: Arises from a lack of financial resources or resilient livelihoods to withstand and recover from disasters.
  • Example: The devastating 2018 floods in Kodagu, Karnataka, destroyed extensive coffee plantations and local infrastructure, imposing a long-term economic burden on the region.
• Crime Vulnerability: Post-disaster chaos often increases susceptibility to exploitation and lawlessness.
  • Example: Following the Nepal earthquake, displaced women and children faced heightened risks of harassment and human trafficking.
• Social Vulnerability: Relates to the psychological, emotional, and structural weaknesses within a community, affecting its coping capacity.
  • Example: The loss of family members and livelihoods causes severe mental trauma, altering community dynamics and social behavior.
• Climate Change Vulnerability: Driven by shifting environmental parameters that amplify the frequency and intensity of extreme weather events.
  • Example: Unsustainable practices like sand mining have left coastal ecosystems highly vulnerable to accelerated erosion and severe flooding.
