Resilience & Recovery
How resilient is human civilization to global catastrophes? And if civilization collapses, would survivors recover? These questions are deeply important to the study of global catastrophic risk and can guide policy to mitigate the consequences.
An Introduction to Resilience & Recovery
Risk is generally quantified as the probability of some harmful event occurring multiplied by the severity of the consequences if it occurs. The global catastrophic risks are defined by their extreme global severity, but work on these risks often concentrates on the probability. To an extent, this is understandable: ideally, society would prevent global catastrophes from occurring in the first place, or at least reduce the probability, and furthermore, the severity of global catastrophes is a dark topic that can be unpleasant to even think about.

Resilience and recovery are two components of the severity of global catastrophes. First, as a catastrophe plays out, a crucial question is the resilience of human civilization to global catastrophes. How severe does a catastrophe need to be before civilization collapses? Second, if civilization does collapse, another crucial question is how successfully the survivors would recover. Would they go on to rebuild civilization, or remain in a diminished state, or die out?
Both of these questions are among the most important across the entire study of global catastrophic risk. Together, they largely determine the ultimate severity of global catastrophes, which is essential for assessing how large the risks are and likewise how to prioritize efforts to address them. Alarmingly, however, neither question has been studied in any substantial depth. GCRI has contributed some research, as have some other groups, but overall this remains a very understudied set of topics.

The study of resilience and recovery is of further value by highlighting opportunities to reduce the severity. Potential measures to increase the resilience of global civilization could include hardening critical infrastructure to withstand extreme catastrophes, adding redundancy to global supply chain networks, and including global catastrophe within plans for continuity of government and operations. Importantly, these measures can have some overlap with measures to protect against less severe catastrophes, including those handled via catastrophe insurance and other for-profit sectors. Pursuing these synergies is a promising direction for global catastrophic risk reduction.
Measures to support post-catastrophe recovery of civilization can include stockpiling food and other resources to aid survivors, building refuges to ensure some people survive the initial event, and developing techniques and technologies that could be of particular use to survivors. Preparedness for the aftermath of global catastrophe is an especially grim domain. Discussions of nuclear war sometimes posit that “the survivors will envy the dead”. This may apply to all of the global catastrophe scenarios that leave some survivors. Furthermore, the preparedness cannot always dovetail on preparedness for less extreme catastrophe scenarios—some measures are specific to global catastrophe. However, this could be the difference between the long-term success or failure of human civilization, so it is an important domain to address.

In addition to being emotionally difficult, resilience and recovery are also difficult to study for intellectual reasons. Both involve extreme complexities related to the character of global civilization and the conduct of human survivors under post-catastrophe conditions. Both also face a fundamental lack of data: global civilization has never previously collapsed. Despite these challenges, resilience and recovery are very important topics to study and address.

Featured GCRI Publications on Resilience & Recovery
Asteroid collision is probably the most well-understood global catastrophic risk. However, this paper, published in the journal Natural Hazards, shows that it’s not so well understood after all, due to uncertainty in the human consequences. If asteroid risk is poorly understood, then so are other global catastrophic risks.
What will be the fate of human civilization millions, billions, or trillions of years into the future? This paper, written by an international group of 14 scholars and published in the journal Foresight, studies several possible long-term trajectories of human civilization, including the radically good and catastrophically bad.
If humanity could survive major global food supply disruptions, it would be much less vulnerable to global catastrophe. This paper, published in the journal Environment Systems and Decisions, studies options to improve global food resilience, covering food stockpiles, agriculture, and alternative foods produced without sunlight.
