Sanitation refers to the improvement of the overall health situation of the environment through the treatment and proper disposal of human excreta and wastewater. In Africa, sanitation takes on a particular dimension since it is at the heart of public health policies, particularly the fight against open defecation, which is at the origin of diseases such as cholera.
From an environmental point of view, sanitation in Africa refers to the fight against pollution caused by wastewater, with the construction of treatment plants. In some parts of Africa, sanitation also includes the reuse of wastewater for irrigation or consumption by populations in countries with limited freshwater resources such as Namibia.
