In general, the ability of a system (ecological or human) to resist damage and recover from a disturbance. In ecology, resilience refers to the ability of the system to return to the pre-disturbed state with no assessment of whether that state is desirable or not. From a social perspective, resilience references the ability to return to the original state but also refers to the ability to recover to a state more likely to resist or recover quickly from future disturbances.
