"The most beautiful thing distinguishing us from the rest of the world is the Nile. There is no other river like it. It's a great river – heavenly – and the life around it is unique." Hamdi, Sudan

Hamdi is a resident of Tuti Island, an island in Sudan where the White Nile and Blue Nile merge to form the main Nile.

He explains to his son the difference in the colour of the waters - the White Nile on the left and the Blue Nile on the right – and how they join here to form one river flowing northwards to Egypt.

In his small truck Hamdi delivers vegetables across the river to the market of Omdurman.
