I want to highlight Mohammed Bah Abba who has won an award for technology innovation. He invented a simple, double pot system that uses wet sand to keep good cooler in hot, dry climates. It’s very simple yet has had a significant impact on the economy in Nigeria. Because perishables last longer, wastage in the food system is reduced. Moreover, because it’s simple it doesn’t require any technology that’s not already present (something inventors of fancy gadgets frequently overlook). It’s a small thing but it’s good to have at least one sign of hope in Africa.
