Analysis of human vulnerability exposure to landslides using AHP- GIS method
Analysis of human vulnerability exposure to landslides using AHP- GIS method
Landslides increasingly affect human health, killing thousands of people annually all over the world. However, human vulnerability is a crucial element in reducing landslide risks. This paper deals with the establishment of an efficient method for human consequences assessment (vulnerability). The adopted methodology is based on a statistical data-driven tool to estimate an individual's probability of death according to the landslide intensity, which can be used directly in landslide risk assessment and mitigation. The evaluation is based on the AHP (Analytical Hierarchical Processes) model to calculate each factor's weight. The work is made via GIS by using an ArcGIS-AHP extension.
In the current research, the five vulnerability factors were identified and mapped from existing documents, works, and new data which came from either remote sensing or fieldwork (Population density, land use, annual average growth rate, urbanization ratio and housing occupation ratio). Then, afterward, each parameter is classified into a number of significant classes based on their relative influence. The obtained human vulnerability map constitutes a powerful decision-making tool in land-use planning, within the national development program in the Northern provinces.
