Sand and gravel mining are amongst the main factors that induces significant impacts on environment, as a result of growing need for building materials and as a source of income for rural communities. This study was conducted to assess the socio-economic and environmental effects of these activities in Maroua, Cameroon. Its objectives include a description of artisanal mining method and identification of its socio-economic and environmental impacts. The study was conducted in a multidisciplinary approach. During the fieldwork, data were collected using questionnaires and focused group discussions were undertaken with those responsible for managing natural resources in the that area. The results reveal that sand mining activity alter river morphology at a faster rate than normal river process, where river reduction of the extraction areas is significantly larger. These activities were responsible for quick resource depletion and adversely affecting the environment and causing disturbances such as, ecological balance, soil degradation, pollution, infrastructure destruction, as well as conflict between miners and communities. Despite the negative impacts, mining activities generate income for all parties involved in the value chain, including the government. Accordingly, based on the research results, there are concerns about sustainable extraction practices by implementing strict rules and government policies.
