“…This context may be determined by, among others, legal obligations, explored administrative levels, the boundaries of the investigated area, or the considered infrastructure sectors and their worthiness of protection (Engels 2018 ; Folkers 2018 ; Bouchon 2006 ). Only in this context, propositions on the criticality of a system component, may it be a facility, network segment, or subsector, can be concluded (Engels 2018 ; Lukitsch et al 2018 ). For example, a segment of a motorway is more critical than a segment of a high street relative to all streets within given boundaries, because a disruption would have more extensive implications for a larger number of people and businesses.…”

“…What is the effect when an infrastructure component breaks down, or services are disrupted? Lukitsch et al ( 2018 ) argue that this question, and thus the question of how to assess criticality, can be answered from a deficiency-oriented perspective. Through this lens, criticality is assessed by investigating the impact of a defective component on the system and population.…”

“…This approach shows that infrastructures are a considerable contributing factor impacting a society’s susceptibility to natural hazards. However, identifying the weak links of the infrastructure system can also be an opportunity to invest strategically in reducing a community’s vulnerability (Lukitsch et al 2018 ).…”

“…The emphasis on consequences implies an understanding of criticality that Lukitsch et al ( 2018 ) coin as function-oriented. The core assumption of this use of the term is that “function [...] is the result of an interplay of individual components” (Lukitsch et al 2018 ) within the infrastructure system. In this context, function or functionality is defined relative to a given or expected supply of services or goods.…”

Systemic criticality—a new assessment concept improving the evidence basis for CI protection

With high certainty, extreme weather events will intensify in their impact within the next 10 years due to climate change-induced increases in hazard probability of occurrence and simultaneous increases in socio-economic vulnerability. Data from previous mega-disasters show that losses from disruptions of critical services surpass the value of direct damages in the exposed areas because critical infrastructures [CI] are increasingly (inter-) dependent. Local events may have global impacts. Systemic criticality, which describes the relevance of a critical infrastructure due to its positioning within the system, needs to be addressed to reduce the likelihood of cascading effects. This paper presents novel approaches to operationalise and assess systemic criticality. Firstly, the paper introduces systemic cascade potential as a measurement of systemic criticality. It takes the relevance of a sector and the relevance of its interdependencies into account to generate a relative value of systemic importance for a CI sector. Secondly, an exemplary sectoral assessment of the road network allows reflecting the spatial manifestation of the first level of cascading effects. It analyses the impact of traffic interruptions on the accessibility of critical facilities to point out the systemically most critical segments of the municipal road network. To further operationalise the spatial dimension of criticality, a normative assertion determining the worthiness of protection of system components is required. A nationwide spatial flood protection plan incorporates this aspect in Germany for the first time. Its formal approval process was initiated in February 2020.

KurzfassungDie räumliche Planung ist aufgerufen, sich im Rahmen des Schutzes kritischer Infrastrukturen am Umgang mit dem Risiko von Ausfällen als besonders wichtig geltender Infrastrukturleistungen zu beteiligen. In diesem Beitrag werden Hinweise auf Überschneidungen zwischen den Sektoren kritischer Infrastrukturen und Bereichen der Daseinsvorsorge untersucht, denen in der fachöffentlichen Diskussion bislang wenig Aufmerksamkeit zuteil wurde. Den Sektoren kritischer Infrastrukturen werden dazu unterschiedliche Auffassungen von Bereichen der Daseinsvorsorge gegenübergestellt. Auch wenn sich die Überschneidungsbereiche nicht genau bestimmen lassen, ist davon auszugehen, dass ein Großteil der als kritisch betrachteten Infrastrukturen an der Bereitstellung von Dienstleistungen beteiligt ist, die der Daseinsvorsorge zugerechnet werden. Die betreffenden Infrastrukturen und Dienstleistungen sind demnach Gegenstand unterschiedlicher politischer Gestaltungsbereiche und darauf bezogener Maßnahmen. Diese Folgerung lädt zur Befassung mit den Implikationen der räumlichen Organisation der Bereitstellung von Daseinsvorsorgeleistungen für den Schutz kritischer Infrastrukturen ein. Ein Perspektivwechsel, die Betrachtung von Zielen und Ansätzen der Daseinsvorsorgeplanung aus der Sicht des Schutzes kritischer Infrastrukturen, kann deren mögliche ‚Nebenwirkungen‘ sichtbar machen. Da das Konzept „kritische Infrastruktur“ Schutzwürdigkeit und Gefahrenpotenzial auf sich vereinigt, eröffnet ein solcher Perspektivwechsel mitunter ungewohnte Ansichten auf die Daseinsvorsorgeplanung und wirft Fragen für Forschung und Praxis auf.
