KW - The services that technical infrastructures provide are essential for the function of the society
KW - as highlighted by many infrastructure crises the last decades. Many of these crises was due to the impact of natural hazard
KW - which future frequency and intensity characteristics might be hard to predict given possible climate change scenarios. Due to physical interdependencies between infrastructures
KW - failures in one infrastructure can spread and cause disturbances in other infrastructures. Additionally
KW - geographical interdependencies means that a given hazard can affect more than one infrastructure simultaneously. As such
KW - hazard impact on infrastructures may give rise to unanticipated cascading consequences if not a system-of-system perspective is taken. The common way to approach critical infrastructure protection is to start with addressing hazards that are likely to aff
KW - decisions are made regarding hazards to consider further. Hazards that have not been identified
KW - or might be underestimated
KW - in the identification phase will then not be addressed
KW - which might be problematic given uncertainties in estimations. Here it is argued that it might be beneficiary to start in the other end by identifying systems’ intrinsic vulnerabilities
KW - i.e. the inability a system to withstand strains
KW - before identifying how specific hazards might impact the system. Although no plausible hazard can currently be imagined
KW - there might be reasons for reducing a particular vulnerability
KW - since in good risk and safety management practice we ought also be well prepared for unknown or uncertain hazards. The aim of this contribution is to twofold. Firstly
KW - to present and discuss a previously developed modelling framework for interdependent infrastructures
KW - inspired from both complexity science and engineering sciences
KW - with special emphasis on ways to model how a system reacts to disturbances and consequences thereof. Secondly
KW - to exemplify a generic geographical vulnerability analysis approach
KW - which has the aim to provide a broad
KW - initial identification of areas most vulnerable hazard impacts as input to decisions related to strengthen infrastructure resilience. Climate change related hazards that may exploit such geographical vulnerabilities include for example flooding
KW - hurricanes
KW - earthquakes
KW - snowstorms
KW - etc. which frequency
KW - intensity or spatial orientation might be associated with great uncertainties. Examples of analysis is given from a previous case study of a railway system
KW - located in southern Sweden. It as an interdependent infrastructure system composed of seven interdependent systems.
