| Zusammenfassung |
Over the last few decades, the island of Madeira has become an important
offshore tourism and business center, with rapid economic and demographic
development that has caused changes to the landscape due to human activity.
In Madeira's recent history, there has been an increase over time in the
frequency of occurrence of damaging landslide and flood events. As a result,
the costs of restoration work due to damage caused by landslide and flood
events have become a larger and larger component of Madeira's annual budget.
Landslides and floods in Madeira deserve particular attention because they
represent the most serious hazard to human life, to property, and to the
natural environment and its important heritage value.
The work reported on in this paper involved the analysis of historical data
regarding damaging landslide and flood events on Madeira (in particular from
1941 to 1991) together with data on geological characteristics, topographic
features, and climate, and from field observations. This analysis showed
that the main factor triggering the occurrence of damaging landslide and
flood events is rainfall, but that the increase in the number of damaging
events recorded on Madeira Island, especially in recent times, seems to be
related mostly to human activity, specifically to economic development and
population growth, rather than to natural factors. |
