We trotted down the hand-dug drive sloping from the newly paved road to Kampala, kicking up little clouds of red dust with each footfall. The morning sun was still angling in sharply from the foothills to the east, but it promised a continuation of the withering heat and drought that was afflicting Uganda. As we passed modest homes with their stands of matooke and maize, we caught a first glimpse of the St. James Primary School, one of four Hello Hub pilot sites in the country.
