Non-agricultural soil uses by communities in uMgungundlovu District and their safety for use

Abstract

South African communities, especially in rural areas, still use indigenous practices such as applying soil paste as sunscreen, building huts  with soil and stones and geophagia among others. This study aimed at identifying non-agricultural uses of soil in uMgungundlovu district of KwaZulu-Natal, South Africa, while focusing on the three areas Elandskop, KwaNxamalala and Willowfontein. Information was  gathered using key informant interviews and household questionnaires. Results showed that the most common soil uses were for  cosmetics and as geophagia, followed by construction, with medicinal use being the least common. Cosmetic use involved using soil as  sunscreen or skin cleaner. While geophagic soil was mostly consumed for enjoyment, to satisfy cravings and least of all as a nutrient  supplement. Medicinal soil was mostly used to treat wounds and skin ailments such as rashes and acne. Users believed that their pre- treatment methods such as boiling, burning or baking before use were effective in reducing microbial loads and other contaminants in  the soil. 

Contribution: This study describes and elucidates on the non-agricultural uses of soil by communities and their safety to users.
