Describe the methods for analysing vulnerability. 

Analyzing vulnerability to climate change involves assessing the exposure, sensitivity, and adaptive capacity of a system, community, or sector to climate-related hazards. Various methods are used to evaluate these aspects, each with distinct approaches and applications. The choice of method depends on the scale, available data, and specific objectives of the assessment. The following are key methods used for analyzing vulnerability in the context of climate change assessment tools:

### 1. Indicator-Based Approaches  
Indicator-based methods use quantitative and qualitative indicators to assess vulnerability by measuring exposure, sensitivity, and adaptive capacity. These indicators are selected based on theoretical frameworks and empirical data.

- Selection of Indicators: Indicators are chosen based on their relevance to climate hazards. Common indicators include temperature and precipitation trends (exposure), population density and land use (sensitivity), and institutional capacity or economic resources (adaptive capacity).  
- Index Construction: Composite indices such as the Vulnerability Index (VI) or Climate Vulnerability Index (CVI) aggregate multiple indicators to provide a comparative measure of vulnerability across different regions or sectors.  
- Data Sources: Data can be collected from national statistics, remote sensing, surveys, or expert assessments.  
- Examples: Human Development Index (HDI), Livelihood Vulnerability Index (LVI), and Social Vulnerability Index (SoVI) are common indices used in climate vulnerability assessments.  

### 2. GIS and Remote Sensing-Based Methods  
Geographic Information System (GIS) and remote sensing techniques are widely used to analyze spatial vulnerability to climate change. These methods help in mapping and visualizing exposure, sensitivity, and adaptive capacity.

- Geospatial Analysis: GIS layers representing climatic, environmental, and socio-economic factors are combined to create vulnerability maps.  
- Remote Sensing Data: Satellite imagery provides real-time information on land use, vegetation health, water resources, and urban expansion, helping in climate change impact assessments.  
- Overlay and Weighted Overlay Analysis: Different thematic _________ _______ ______ _____ ____ _________.
