Cost on infrastructure of past natural hazards events (1972-2007)

Indicator	[CHF/ hectares tourism region]
Range	[-%]
Control for	DEMAND: Changes in tourists flow (-) SUPPLY: Changes in monetary and employment flows (-)
Influence on vulnerability	The higher the risks of natural hazards, the less the number of tourists visiting the region. The higher the possible costs of natural hazards on infrastructure, the higher the exposure of the region.
Trend	Linear ↑
Data source	Calculated from data delivered by Hilker (Swiss Federal Research Institute WSL - personal communication)
Remarks	Natural hazards considered are: naturally triggered flood, debris flow, landslide (since 1972) and rockfall (since 2002) events. These will very probably a change in frequency, intensity, and distribution in the future due to climate change (Bader, Kunz et al (2000); Hilker, Badoux et al.(2009)). However, as stated in Hilker, Badoux et al. (2009), no statistically significant trend has been found until now for the Swiss Alps. The CLISP project is looking at the question. Inflation was considered in the calculation.
