Many African cities struggle to supply safe, potable water to their residents. One of the main reasons for this is urbanisation; cities’ populations grow rapidly as more people move to them from rural areas. Another reason, in some regions, is water scarcity.
Researchers have long suspected that informal urban neighbourhoods are lagging behind their formal counterparts when it comes to accessing safe drinking water. But this reality can be obscured when data is aggregated to city-scale rather than being examined at a granular, localised level.
