There are close to 4 million people living in refugee camps across Africa. Of the more than 300 camps, nearly 70% are situated within 30km-50km of an international border. They include some of the largest camps in the continent, such as Kakuma in northern Kenya, Nyarugusu in western Tanzania and Bidibidi in north-western Uganda.
The closer the camp is to an international border, the easier it is for people on both sides of the border to interact.
