תקציר	Adaptive capacity assessment evaluates the ability of a community, sector, or system to adjust to climate variability and change, to moderate harm, and to seize opportunities. It is the third and most actionable component of the IPCC vulnerability framework, the part that captures why two equally exposed and sensitive places can fare very differently. Barry Smit and Johanna Wandel's influential synthesis reframed vulnerability assessment around adaptive capacity and argued for a bottom-up, practitioner-oriented approach grounded in local knowledge of real exposures and coping. The IPCC Fourth Assessment Report chapter on adaptation, by Adger and colleagues, catalogued the determinants of adaptive capacity, economic resources, technology, information, infrastructure, institutions, and equity, and the barriers that limit it in practice. Rather than producing a single index number, the assessment builds a rich, context-specific picture of what enables and constrains adaptation. Its purpose is to identify concrete entry points for strengthening the capacity to cope with a changing climate.	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.
