Bafoussam is a city in the West Cameroon region located in the highlands. This city is facing an unprecedented demographic growth with the consequence of urban sprawl and the development of precarious neighbourhoods in which the environment and the health of the populations are increasingly degraded. In the face of this situation, the Regional and Local Authorities are involved on a daily basis in improving the living environment of the city dwellers in the study area. This study therefore aims to draw up a typology of the local authorities in the city of Bafoussam and to decipher their intervention strategies in the precarious neighbourhoods. To this end, the study was based on preliminary documentary research, field observations, semi-structured interviews with officials of the local authorities and surveys by questionnaire of a sample of 551 households living in precarious neighbourhoods divided into three strata: Stratum A: 3 neighbourhoods for a total of 93 households surveyed, stratum B: 7 neighbourhoods for a total of 178 households surveyed and stratum C: 8 neighbourhoods for a total of 280 households surveyed. The use of a Global Positioning System (GPS) then made it possible to geolocate the various projects carried out by the CSOs in the city. The analysis of the various data shows that there are CTDs in the city of Bafoussam that actively participate in the preservation of the environment and the health of the populations of precarious neighbourhoods. These CTDs carry out several activities related to the sanitation of the living environment of the populations, access to drinking water, recycling of plastic waste etc.
