![LA RESILIENZA
DEI SISTEMI
In ecology, resilience is the capacity of an ecosystem to
respond to a perturbation or disturbance by resisting
damage and recovering quickly. Such perturbations and
disturbances can include stochastic events such as fires,
flooding, windstorms, insect population explosions, and
human activities such as deforestation, fracking of the
ground for oil extraction, pesticide sprayed in soil, and the
introduction of exotic plant or animal species.
Disturbances of sufficient magnitude or duration can
profoundly affect an ecosystem and may force an
ecosystem to reach a threshold beyond which a different
regime of processes and structures predominates.
British Standard, BS65000(2014) defines "organisational
resilience" as "ability of an organization to anticipate,
prepare for, and respond and adapt to incremental change
and sudden disruptions in order to survive and
prosper."[1]
In recent years, a new consensus of the concept of
resilience emerged as a practical response to the
decreasing lifespan of organisations[2] and the from key
stakeholders, including boards, governments, regulators,
shareholders, staff, suppliers and customers to effectively
address the issues of security, preparedness, risk, and
survivability.

Una visione ampia dei sistemi: robustezza e resilienza.
The document discusses the concept of resilience across various disciplines such as materials engineering, ecology, psychology, and urban systems, emphasizing its importance in adapting to disturbances and recovering from shocks. It highlights the complexity of urban resilience, which requires a multidisciplinary approach to understand the interactions among urban components and their ability to restore functionality after disruptions caused by either natural events or human activities. The text advocates for the development of skills such as effective communication, collaboration, and integration of information to enhance urban resilience strategies.

Quando specie animali e vegetali presentano alti tassi di resilienza vengono definite specie a strategia r In generale quindi, e per un ambiente urbano, la resilienza è definita come la capacità della comunità (o un sistema ecologico) nei suoi componenti primari, di ritornare al suo stato iniziale, dopo essere stata sottoposta a una perturbazione o shock che l’ha allontanata da quello stato; tali alterazioni possono essere causate sia da eventi naturali (es. terremoto), sia da attività antropiche e terroristiche.

A Black Swan is an event with the following three attributes. 1. First, it is an outlier, as it lies outside the realm of regular expectations, because nothing in the past can convincingly point to its possibility. Rarity -The event is a surprise (to the observer). 2. Second, it carries an extreme 'impact'. Extreme “impact” - the event has a major effect. 3. Third, in spite of its outlier status, human nature makes us concoct explanations for its occurrence after the fact, making it explainable and predictable. Retrospective (though not prospective) predictability - After the first recorded instance of the event, it is rationalized by hindsight, as if it could have been expected; that is, the relevant data were available but unaccounted for in risk mitigation programs. The same is true for the personal perception by individuals. Black Swans F. Petrini.
