2. Identify Vulnerability Scoring Systems and Metrics

2.1 Vulnerability Scoring Framework

• Exposure: The degree to which a region or sector is exposed to climate hazards (e.g., floods, droughts, heatwaves, storms).
• Sensitivity: The extent to which the region or sector is sensitive to climate impacts (e.g., crop yield sensitivity to temperature changes, or health vulnerability to heat stress).
• Adaptive Capacity: The ability of the region or sector to cope with or adapt to climate change (e.g., infrastructure quality, governance, community preparedness).

2.2 Vulnerability Index (VI) Formula

Each region or sector will be scored using a standardized vulnerability index, which could be based on the following weighted formula: Vulnerability Index (VI)=(Exposure×w1)+(Sensitivity×w2)+(Adaptive Capacity×w3)\text{Vulnerability Index (VI)} = \left( \text{Exposure} \times w_1 \right) + \left( \text{Sensitivity} \times w_2 \right) + \left( \text{Adaptive Capacity} \times w_3 \right)Vulnerability Index (VI)=(Exposure×w1​)+(Sensitivity×w2​)+(Adaptive Capacity×w3​)

Where:

• w1,w2,w3w_1, w_2, w_3w1​,w2​,w3​ are the weights assigned to each dimension, reflecting their relative importance. These weights can be adjusted based on sector-specific or regional priorities.

2.3 Key Metrics for Each Dimension

• Exposure:
  • Frequency of climate-related events (e.g., flooding, droughts).
  • Intensity of climate hazards in the region (e.g., temperature rise, precipitation changes).
  • Predicted future climate events (e.g., projected sea-level rise or extreme heat events).
• Sensitivity:
  • Vulnerability of key infrastructure (e.g., roads, hospitals, energy grids).
  • Dependence on climate-sensitive resources (e.g., water, agriculture).
  • Population groups at risk (e.g., elderly, children, low-income groups).
• Adaptive Capacity:
  • Availability of resources for climate adaptation (e.g., financial, technical, social capital).

4. Apply Vulnerability Scoring System to Each Region and Sector

4.1 Calculate Vulnerability Scores

Using the exposure, sensitivity, and adaptive capacity metrics, calculate the vulnerability index (VI) for each region and sector.

• For example, if we are assessing flood vulnerability in a coastal region:
  • Exposure could be determined by flood risk maps, historical flooding events, and sea-level rise projections.
  • Sensitivity would be based on the region’s infrastructure (e.g., flood defenses), population density, and economic reliance on sectors vulnerable to flooding (e.g., tourism, agriculture).
  • Adaptive Capacity could consider the local government’s capacity to implement flood protection measures and community awareness of flood risks.

4.2 Interpret Results

Once the vulnerability scores for each region and sector are calculated, analyze the data to identify the most vulnerable areas. This could be done using heatmaps, vulnerability rankings, and comparative charts.
