| Zusammenfassung |
| This paper presents a model of factors influencing levels of human losses
from natural hazards at the global scale, for the period 1980–2000. This
model was designed for the United Nations Development Programme as a building
stone of the Disaster Risk Index (DRI), which aims at monitoring the
evolution of risk. Assessing what countries are most at risk requires
considering various types of hazards, such as droughts, floods, cyclones and
earthquakes. Before assessing risk, these four hazards were modelled using
GIS and overlaid with a model of population distribution in order to extract
human exposure. Human vulnerability was measured by crossing exposure with
selected socio-economic parameters. The model evaluates to what extent
observed past losses are related to population exposure and vulnerability.
Results reveal that human vulnerability is mostly linked with country
development level and environmental quality. A classification of countries is
provided, as well as recommendations on data improvement for future use of
the model. |
