The concept of resilience has two dimension: the inherent strength of an entity to better resist to unexpected and violent events and the capacity of this entity to bounce back rapidly from the impact.

Increasing resilient (and reducing vulnerability) can therefore be achieved either by enhancing the entity’s strength, or by reducing the intensity of the impact, of both. It requires a complex strategy and a broad system prospective aimed at both reducing the multiple risks of a crisis and at the same time improving rapid coping and adaptation mechanisms at European, local, national and regional level.

Enhancing resilience calls for a long-term approach, based on alleviating the underlying causes conductive to crises, and enhancing capacities to better manage future uncertainty and change.

The term “resilience” originated in 1970s in the field of ecology from the research of C.S. Holling, who defined resilience as “a measure of the persistence of systems and of their ability to absorb change and disturbance and still maintain the same relationship between populations or state variables” (Holling, 1973)

In time, the notion of resilience has known different description and definitions that would have underpinned different aspects.

 Resilience Concepts  Characteristics  Focus on  Context
 Engineering resilience  Return time, efficiency  Recovery, constancy  Vicinity of a stable equilibrium
 Ecological resilience  Buffer capacity, withstand shock, maintain funcion  Persistence, robustness  Multiple equilibria, stability landscape
Social-ecological resilience Interplay disturbance and reorganization, sustaining  and developing Adaptive capacity transformability, learning, innovation  Integrated system feedback, cross-scale dynamic interactions
