USING GEOMATICS FOR ASSESSING VULNERABILITY TO CUTANEOUS LEISHMANISAIS. APPLICATION TO THE WILAYA OF BATNA (ALGERIA)

Abstract

If the typology of epidemics varies considerably, their causes remain substantially related to
many physical environment factors. The fact remains that the problem of vector-borne diseases is complex in
view of the diversity of these diseases, the large number of vulnerabilities associated with them, and also the
objective assessment of the impact of each of these factors. The use of geomatic tools, such as geographical
information systems (GIS) and remote sensing techniques as spatial environmental phenomena and through
the implementation of a GIS database, has enabled us to highlight the spatial distribution of these diseases and
their magnitude, and has allowed us to subsequently relate them to some environmental factors that might
explain the emergence of the disease and its importance. The results clearly show that approximately 48.89%
of the total area of the province was found to be highly vulnerable, 2.83% at moderate vulnerability, while
48.28% of the province had low vulnerability.
