Critical infrastructures (CI) are increasingly being evaluated for their sustainability and resilience in light of the notable increase in high-impact natural hazard events that influence socioeconomic well-being [1]. Resilience, as Ferreira Gonçalves et al. (2023) explained which comes from the Latin word “resilio”, literally means “to leap back” and denotes a system attribute characterized by the ability to recover from challenges or disruptive events [3].Nowadays, Resilience defines as the capacity and ability of infrastructures to anticipate, absorb, adapt to, and rapidly recover from variety disturbances while preserving and maintaining vital functions and minimizing impacts on people, the economy, and the environment. This concept is essential to ensure that infrastructures can withstand and recover from a wide range of natural disasters and man-made hazards, such as climate change, cyber-attacks, and other unexpected challenges.
This paper addresses the holistic methodology of how resilience factors can be integrated and categorized. This study provides a state-of-the-art review as well as establishes a database of resilience indicators from previous EU projects about different methodologies of risk and resilience implemented and compares them with the ongoing NBSINFRA project. Finally, it leads to forming the basis for the resilience framework, which will be based upon quantitative measurable resilience indicators.
PRISMA methodology which stands for Preferred Reporting Items for Systematic Reviews and Meta-Analyses has been used. This method provides a structured framework for researchers to plan, conduct and report their evaluations comprehensively.
In this paper, 18 former EU projects are being assessed based on the eligibility criteria that have been defined in terms of their resilience indicators (essential metrics), risk methodologies and sustainability indicators. A dataset is formed based on these metrics as well as each project’s outputs, developed toolkit and scopes. In this aspect, especially considering huge projects such as NBSINFRA, this study aims to create a pathway to show the connection and set an integrated framework to achieve more resilient CI and draw an approach to a systematic assessment showing the importance of collective assessment aligned with sustainability indicators.
