Multi-hazard risk to global port infrastructure and resulting trade and logistics losses

Abstract Despite their economic importance, the risk that ports face from multiple natural hazards has not yet been monetised on a global scale. Here, we perform an asset-level analysis of port infrastructure hazards, quantifying to physical asset damages and logistics services (i.e. port-specific risk) maritime trade flows at-risk risk). We find 86% majority are exposed more than three hazards. Globally, totals 7.5 USD bn per year, with 32% attributed tropical cyclone impacts. In addition, 63.1 is every as fraction total being particularly high in Small Island Developing States. Our result underline resilience determined by various critical factors, such engineering standards, operational thresholds, recovery duration, vary widely across ports, requiring tailored solutions improve resilience.
