Tóm tắt	A climate vulnerability index is a composite indicator that combines measures of exposure to climate hazards, sensitivity to those hazards, and adaptive capacity into a single comparable score for places or populations. The conceptual backbone is the IPCC framing, articulated clearly by Smit and Wandel, in which vulnerability rises with exposure and sensitivity and falls with the capacity to adapt. The measurement machinery owes much to Susan Cutter's Social Vulnerability Index, which showed how to select, normalize, and statistically reduce many socioeconomic variables into a defensible index of who is most at risk. A climate vulnerability index merges these traditions: it assembles biophysical exposure indicators with social sensitivity and adaptive-capacity indicators, puts them on a common scale, and aggregates them. The output ranks counties, communities, or households so that scarce adaptation resources can be targeted. Because it is a composite, every step, indicator choice, normalization, weighting, embeds judgments that must be made transparent.	The Livelihood Vulnerability Index (LVI) is a composite-indicator method for assessing the vulnerability of households and communities to climate variability and change, developed by Micah Hahn, Anne Riederer and Stanley Foster in a 2009 case study in Mozambique. It is built from household survey data organized into major components — typically socio-demographic profile, livelihood strategies, social networks, health, food, water, and exposure to natural disasters and climate variability — each composed of standardized sub-indicators. These are normalized to a common scale, averaged into sub-components and weighted major components, and aggregated into an overall index. A companion formulation, the LVI-IPCC, reorganizes the same indicators into the Intergovernmental Panel on Climate Change's contributing factors of exposure, sensitivity, and adaptive capacity, offering a pragmatic, data-driven way to compare vulnerability across places and to target adaptation.
