Résumé :

Solid waste management is an urgent global challenge, with urban areas producing approximately 1.3 billion tons per year, or 1.2 kg per inhabitant daily, according to the World Bank (2012). Rapid urbanization and population growth increase waste production, particularly in Cameroon, where insufficient infrastructure and unregulated disposal exacerbate environmental and health risks. In the Ngaoundéré Vina metro area, the random selection of waste sites can cause groundwater contamination and air pollution, underscoring the urgency of systematic suitability site selection for sustainable management. This study employs Geographic Information Systems (GIS) and the Analytic Hierarchy Process (AHP) to evaluate suitable waste disposal sites. The results show that 353,754 km² and 293,805 km² of the modeled area, or 47.47%, was deemed very suitable and highly suitable for waste disposal, while 258,516 km² and 61.38 km² (23.45%) was deemed low and very low suitable. These findings provide actionable insights for local authorities to reduce potential groundwater contamination risks and protect public health.
