2. Introduction

Climate change is reshaping the global landscape, with rising temperatures, more frequent extreme weather events, and shifting environmental patterns creating new challenges for communities and sectors worldwide. Understanding these vulnerabilities is crucial to formulating effective adaptation strategies and climate resilience initiatives.

This report presents an analysis of the vulnerability of five regions and sectors, employing a vulnerability index that considers exposure, sensitivity, and adaptive capacity. These metrics provide a comprehensive overview of the areas most at risk and guide the development of targeted policy actions.

2.1 Objective of the Report

The primary objective is to:

• Assess vulnerability of various regions and sectors.
• Identify key climate threats.
• Provide data-driven recommendations to reduce vulnerability and enhance adaptive capacity.

---

3. Methodology

The vulnerability assessment follows a structured scoring system designed to quantify vulnerability levels based on three key dimensions:

• Exposure: The level of climate hazard (e.g., floods, drought, extreme heat).
• Sensitivity: How susceptible a region or sector is to these climate hazards (e.g., economic dependence on climate-sensitive resources).
• Adaptive Capacity: The ability to manage or adapt to these climate impacts (e.g., infrastructure quality, governance).

Each region and sector was evaluated using quantitative data (e.g., historical climate data, socioeconomic factors) and qualitative data (e.g., community consultations, expert interviews). These metrics were then weighted according to their relevance to each region and sector to generate the vulnerability index (VI).

3.1 Vulnerability Scoring System

Vulnerability Index (VI) formula: VI=(Exposure×w1)+(Sensitivity×w2)+(Adaptive Capacity×w3)\text{VI} = (\text{Exposure} \times w_1) + (\text{Sensitivity} \times w_2) + (\text{Adaptive Capacity} \times w_3)VI=(Exposure×w1​)+(Sensitivity×w2​)+(Adaptive Capacity×w3​)

Where w1,w2,w3w_1, w_2, w_3w1​,w2​,w3​ represent the weights for each dimension. Scores range from 0 (low vulnerability) to 1 (high vulnerability).

2. Introduction

As climate change intensifies, regions and sectors are experiencing growing vulnerabilities that threaten both human and economic well-being. Understanding the magnitude of these risks is vital for effective climate adaptation and resilience-building. This report introduces a vulnerability index that combines exposure, sensitivity, and adaptive capacity to determine the overall climate vulnerability of key regions and sectors.

2.1 Objective of the Report

The report aims to:

• Provide a climate vulnerability index to quantify the risk levels across regions and sectors.
• Offer clear policy recommendations for governments, NGOs, and community organizations to tackle these vulnerabilities.

2.2 Key Methodology

To assess vulnerabilities, each region and sector is scored across three dimensions:

• Exposure: The degree to which an area or sector is subject to climate hazards (e.g., heatwaves, floods, drought).
• Sensitivity: The extent to which an area or sector is impacted by these hazards (e.g., economic losses, health impacts).
• Adaptive Capacity: The ability of a region or sector to mitigate or adapt to the climate impacts (e.g., infrastructure, resources, policies).

The vulnerability index (VI) is calculated using the following formula: Vulnerability Index (VI)=(Exposure×w1)+(Sensitivity×w2)+(Adaptive Capacity×w3)\text{Vulnerability Index (VI)} = (\text{Exposure} \times w_1) + (\text{Sensitivity} \times w_2) + (\text{Adaptive Capacity} \times w_3)Vulnerability Index (VI)=(Exposure×w1​)+(Sensitivity×w2​)+(Adaptive Capacity×w3​)

Scores range from 0 (low vulnerability) to 1 (high vulnerability).
