Zusammenfassung |
Efficiently reducing natural hazard risks requires a thorough understanding
of the costs of natural hazards. Current methods to assess these costs employ
a variety of terminologies and approaches for different types of natural
hazards and different impacted sectors. This may impede efforts to ascertain
comprehensive and comparable cost figures. In order to strengthen the role of
cost assessments in the development of integrated natural hazard management,
a review of existing cost assessment approaches was undertaken. This review
considers droughts, floods, coastal and Alpine hazards, and examines
different cost types, namely direct tangible damages, losses due to business
interruption, indirect damages, intangible effects, and the costs of risk
mitigation. This paper provides an overview of the state-of-the-art cost
assessment approaches and discusses key knowledge gaps. It shows that the
application of cost assessments in practice is often incomplete and biased,
as direct costs receive a relatively large amount of attention, while
intangible and indirect effects are rarely considered. Furthermore, all parts
of cost assessment entail considerable uncertainties due to insufficient or
highly aggregated data sources, along with a lack of knowledge about the
processes leading to damage and thus the appropriate models required.
Recommendations are provided on how to reduce or handle these uncertainties
by improving data sources and cost assessment methods. Further
recommendations address how risk dynamics due to climate and socio-economic
change can be better considered, how costs are distributed and risks
transferred, and in what ways cost assessment can function as part of
decision support. |
