#3 Finding water with Oom Gideon
Loading player...
Gideon Groenewald holds PhDs in palaeontology, hydrology and geology and he has walked the Karoo studying drought. Using satellite imagery and prayer, he discovers over a dozen boreholes a week, most recently for Gift of the Givers, in drought-stricken parts of the country, with 90% accuracy. His story matters because he and his team help communities find solutions to water problems and because the Karoo is a contested fracking site.
