-Vulnerability is the extent to which people are at risk to suffer negative consequences from [[Variability_and_extreme_events|climate variability and extreme events]] or the effects of climate change. Vulnerabilities appear in different places: A small farmer family living in a flood-prone area can be called vulnerable to climate change, but so can be an economic sector such as rain-fed agriculture as a whole. Depending on the questions at hand, the vulnerability of such different elements of a society (''exposure units'') must be assessed.

-Adaptation strategies typically draw on vulnerability assessments. These centre on the most vulnerable groups, sectors or systems and identify areas with a need for action. In situations of high [[Uncertainty|uncertainty,]] it is most appropriate to reduce vulnerability to climate change and increase the population's resilience. In cases where [[Uncertainty|uncertainty]] is less severe and change can be predicted to some extent, direct impact-related [[(General) Adaptation measures|adaptation measures]] are feasible (see also [[Framework planning and coordination|framework planning and coordination]]).
+Adaptation means to reduce vulnerability. In agriculture, this can be achieved by lowering exposure, such as building stronger flood defences or relocating, or by lowering sensitivity, such as moving to more drought-resistant crops. Adaptation can also mean building adaptive capacity: Providing a microcredit or subsidy scheme for individual farmers increases their adaptive capacity if the problem is a lack of funds for adaptation.

-Vulnerability assessments (VAs) employ different methods to identify and measure vulnerabilities of a society, sometimes called a social-ecological system in the literature. This term emphasises that the vulnerability of real people is mediated by social factors and not determined by climate change and ecosystems alone. VAs explore these links between ecology and society in order to find out the nature and extent to which climate change is actually harmful to people's livelihoods. They also help mitigate two key [[Uncertainty|uncertainties]] about climate change, that is, what to adapt to and [[Overview of the Adaptation Process|how to adapt]].
