A rapidly spreading invasive pest now threatens crops across the continent.
Tobias Okwara is a farmer in Kayoro Parish in southeastern Uganda. In the midst of a long drought that began in May 2016, he and his neighbors got together to discuss what to do. Food was becoming scarce, and they hoped to recover quickly once the rains started again. They decided they would pool their meagre resources and plant a large communal field of maize. By spring 2017, the rains had finally returned, and their maize was thriving.
