Assessment of potential risks related to mass movement hazards along the Southern Escarpment of the Bamileke Plateau (West-Cameroon Highlands)

Abstract

The South Escarpment of the Bamileke Plateaus (ESPB) is located on the LVC and is part of the HTOC. It is subject to many risks related to mass movements. This region has significant potential for agro-pastoral activities. It is for this reason that the demographic explosion is important there. The population in place practices many activities and owns several assets. This is the essence of the vulnerability to mass movements in this region. This vulnerability is human and material. Assessing the risk of mass movement also requires an assessment of vulnerability. Field campaigns have made it possible to identify the various vulnerable sites. Falling rocks, landslides and subsidence are the main mass movements in the region. The mass movement density map and probable area map highlight these mass movements. By questioning the populations and using the documents, we estimated the losses. The population is estimated at around 195.181 inhabitants. The estimated loss of agro-pastoral activities is 62.251.150 FCFA or 115.455.96 USD. The ESPB is covered by approximately 279.0335 km of road. It is full of many homes and public buildings. The estimated loss of buildings and properties amounts to 2778509.700 FCFA or 5151001.33 USD. By questioning the populations and using the documents, we estimated the losses.
