I don’t know where to start. I wish I had taken my wife. Who am I without my school certificates? These three remarks by refugees, scribbled into notebooks by The Niles correspondents, support the Sudanese proverb that ‘experience is a solid walking stick’. War, hunger and poverty have repeatedly forced both Sudanese and South Sudanese to flee their homes. Right now more than 4.5 million people are on the road in the two countries, like these passengers on a bus from Khartoum to Shendi. The fifth edition of The Niles documents their journeys, following their routes to neighbouring villages, fast-expanding cities or the other side of the globe, revealing diverse experiences with a recurring theme: When you leave home, the familiar is lost but the essential remains.
