The vulnerability of transport logistics to extreme weather events

Records of international organisations and reinsurance companies highlight the rising damages caused by extreme weather events. The burden of these hazards for transport and possible adaptation strategies have been explored by the European research project WEATHER. In this paper, we summarise the main findings and link them to supply chain security. In this context, we develop a method for assessing the criticality of certain elements in large networks. This is crucial as shipping constitutes a major element of supply chains and as world economic conditions simultaneously demand for cost savings and more reliability in supply mechanisms. Our findings suggest that extreme weather has significant impacts on transport systems. Highest losses are estimated for road, and here in for user delays and accident consequences. We conclude that weather forecasts should be continuously monitored and the development of business continuity plans on company level should be fostered.
