| Zusammenfassung |
| Inundations and landslides are widespread phenomena in Italy, where they
cause severe damage and pose a threat to the population. Little is known
about the public perception of landslide and flood risk. This is surprising,
as an accurate perception is important for the successful implementation of
many risk reduction or adaptation strategies. In an attempt to address this
gap, we have conducted two national surveys to measure the perception of
landslide and flood risk amongst the population of Italy. The surveys were
conducted in 2012 and 2013, and consisted of approximately 3100
computer-assisted telephone interviews for each survey. The samples of the
interviewees were statistically representative for a national-scale
quantitative assessment. The interviewees were asked questions designed to
obtain information on (i) their perception of natural, environmental, and
technological risks, (ii) direct experience or general knowledge of the
occurrence of landslides and floods in their municipality, (iii) perception
of the possible threat posed by landslides and floods to their safety, (iv)
general knowledge on the number of victims affected by landslides or floods,
and on (v) the factors that the interviewees considered important for
controlling landslide and flood risks in Italy. The surveys revealed that the
population of Italy fears technological risks more than natural risks. Of the
natural risks, earthquakes were considered more dangerous than floods,
landslides, and volcanic eruptions. Examination of the temporal and
geographical distributions of the responses revealed that the occurrence of
recent damaging events influenced risk perception locally, and that the
perception persisted longer for earthquakes and decreased more rapidly for
landslides and floods. We explain the difference by the diverse consequences
of the risks. The interviewees considered inappropriate land management the
main cause of landslide and food risk, followed by illegal construction,
abandonment of the territory, and climate change. Comparison of the risk
perception with actual measures of landslide and flood risk, including the
number of fatal events, the number of fatalities, and the mortality rates,
revealed that in most of the Italian regions, the perception of the threat
did not match the long-term risk posed to the population by landslides and
floods. This outcome points to a need to foster an understanding of the
public towards landslide and flood hazards and risks in Italy. |
