Resilience means that the risks have been considered and managed to achieve an acceptable level of performance given the available information, and that capacities to withstand and recover from shocks are in place (OECD, 2014a). In the case of protective infrastructure (such as flood defences) this will be the assets protected by the defences. For other infrastructure, it will be the costs resulting from damage or disruption to the asset (e.g. business interruption from loss of electricity supply). Considering climate impacts for individual assets, such as a bridge or a railway line, is necessary but not sufficient to ensure that the system functions reliably despite a changing climate.
