Every time I visit Katine, in north-east Uganda, an image remains in the mind for months afterwards. In May, it was a long queue of girls laughing and chatting as they waited at a dirty water pump for hours to fill their jerrycans. In September, it was the eager face of an 18-year-old boy who proudly showed me his school report and told me how it took him three and a half hours to walk to school – and three and a half hours back. I looked with incredulity at the teachers' praise for his schoolwork. When could he find time to do his homework?
