    GIS Based Multi-Criteria Decision Analysis for Landslide Susceptibility Mapping in Chimanimani District, Zimbabwe
    Author(s): Never Mujere* and Archford V Chikanya

    In this study, Geographic Information System based Multi-Criteria Decision Analysis (GIS MCDA) has been used for landslide hazard zonation. The Analytical Hierarchical Process (AHP) was applied for susceptibility assessment of landslides in Chimanimani district of eastern Zimbabwe. Six causal factors comprising slope, aspect, drainage, geomorphology, geology and land cover were analysed, evaluated and weighted. The susceptibility map was generated using the weighted overlay technique. The map validated by overlaying it with observed landslides during Cyclone Idai in March 2019. Area classified as highly susceptible covered 42.3%, moderately susceptible occupied 47.9% and lowly susceptible covered 9.6% of the district... View More»
