abstract = {Groundwater pollution risk modelling is an important asset
to improve groundwater management and protection. In this
study, we assess the temporal dynamics of groundwater
pollution risk at the continental scale, using the DRASTIC
model. The approach was developed using continental-scale
data on soil properties, topography, land use, geology,
hydrogeology, and climate with a resolution of 15 × 15 km2.
We compared continental-scale groundwater pollution risk for
the years 1990, 2000, and 2010. The results showed
significant inter-annual variations of the spatial
distribution of pollution risk. Changes were mainly
concentrated in the area of the Nile Delta, around the Lake
Victoria, in North Africa, and in coastal West Africa
(predominately in Nigeria). We found that the increase in
pollution risk was mainly related to the increase in the
population density in these regions. The proposed
methodology for modelling the temporal dynamics of
groundwater pollution risk could support the monitoring of
the Sustainable Development Goal 6, which focus in
particular on the preservation of the freshwater resources
against future threats},
