Analyzing vulnerability to climate change is a critical step in understanding how different systems, communities, and ecosystems are likely to be affected by climate variability and change. Vulnerability assessment helps policymakers, researchers, and planners design effective adaptation strategies and prioritize interventions. It involves evaluating the exposure, sensitivity, and adaptive capacity of the affected entities. There are several methods and tools that have been developed to assess vulnerability to climate change, ranging from qualitative approaches to quantitative and model-based techniques. One widely used approach is the framework-based vulnerability assessment, which relies on the conceptual understanding of vulnerability as the interaction between exposure, sensitivity, and adaptive capacity. Exposure refers to the degree to which a system is subject to climatic stressors, such as extreme temperatures, floods, or droughts. Sensitivity reflects the degree to which a system is affected by these stressors, which can vary according to ecological, social, or economic characteristics. Adaptive capacity represents the ability of a system to adjust, cope, or recover from climate impacts. This framework allows analysts to identify which components of a system are most at risk and to develop targeted adaptation strategies. It is often used in combination with participatory approaches where local stakeholders provide information on their experiences and perceptions of climate impacts. Participatory Vulnerability Assessment (PVA) is another method that emphasizes the involvement of local communities in identifying vulnerabilities. This approach recognizes that local knowledge is critical for understanding context-specific impacts, coping strategies, and adaptation options. Techniques under PVA include participatory rural appraisal, focus group discussions, and community mapping exercises. These methods are particularly effective in areas where data is scarce, and they help capture the social and cultural dimensions of vulnerability, including livelihood dependencies, gender issues, and traditional coping mechanisms. Participatory methods also foster community engagement and empower local populations to actively contribute to adaptation planning. Quantitative methods for vulnerability assessment often involve index-based approaches. One such example is the creation of a Climate Vulnerability Index (CVI), which combines various indicators related to exposure, sensitivity, and adaptive capacity into a
