ABSTRACT: Natural
disasters are not negligible factors that have significant impacts on a
country’s development. Madagascar cannot escape cyclones, floods and drought
due to its geographical situation. The objective in this work is to assess the
risks and vulnerability to these hazards in order to strengthen the resilience
of the Malagasy population. Our approach is based on multi-criteria spatial
analysis using the Analytical Hierarchy Process (AHP). The results form
decision spatial information that can be used at the strategic level of natural
risk and disaster management. This work focuses on the degree of vulnerability
and it was found in this study that the Androy and Atsimo-Atsinanana regions
are the most vulnerable to major hazards in Madagascar not only because of
their exposure to risk but also because of their very low socio-economic
status.
