文摘

Even in the absence of serious injuries and fatalities, landslide and flood events can have significant socio-economic impacts. These include the severance of access to and from relatively remote communities for services and markets for goods; employment, health and educational opportunities; and social activities. The economic impacts can be classified as: direct economic impacts, direct consequential economic impacts, and indirect consequential economic impacts. In addition, the vulnerability shadow cast can be extensive and its geographical extent can be determined by the transport network rather than the relatively small footprint of the event itself. Using a number of debris flow events and a flood event in Scotland this paper places values on the economic impacts of landslides and floods. It also demonstrates the widespread impact of the events by means of the vulnerability shadow that is cast.
