Namibia is an arid country where many rural and urban centres depend on ephemeral rivers for their water supply. These water sources are, however, limited and display seasonal salinisation. Fog occurs along the coast and extends for some distance inland, and it could be used as a source of drinking water. Data on groundwater salinisation and fog deposition were collected at villages of the indigenous communities and at the Gobabeb Training and Research Centre (GTRC) in the Central Namib Desert. Fog collection experiments were done with Standard Fog Collectors (SFCs) and 1-m2 fog collectors made from the Raschel mesh that is used in SFCs from 1996 onwards. The results indicate that fog occurs throughout the year and that it has low major ion concentrations (chemical composition).
