All social, citizen, environmental and professional actors around the world are affected by ecological problems. The changes that societies are currently experiencing such as loss of biodiversity and global warming are caused by anthropogenic activities. For Burundi, Lake Tanganyika is facing increasing pollution. The latter is number from various sources such as sewage, agricultural, industrial and household waste. Pollution has effects on human health, biodiversity and the local economy. This present dissertation attempts to answer the question of sociocultural perceptions and practices regarding the pollution of the waters of Lake Tanganyika. We conducted field research in the three urban communes of the city of Bujumbura, notably Muha, Mukaza and Ntahangwa. The ethnographic results show that the pollution of Lake Tanganyika is due to cultural considerations and the lack of knowledge of the population regarding the impacts of pollution.fr
