BetaBetaDataset
To provide data on groundwater pollution risk in Africa.
Groundwater pollution risk is determined both by the intrinsic vulnerability of the aquifer and the existence of potentially polluting activities at the soil surface
Data consists of vulnerability and pollution risk of groundwater and nitrate concentration data of groundwater as a proxy of pollution risk. Groundwater pollution risk is categorized as: very low, low, moderate, high and very high.
Data is obtained by combining a groundwater vulnerability model (based on the DRASTIC method) with land use/land cover (from the GlobCoverdatat set) using an additive model.
