It’s one of the world's deadliest human migration routes. The journey from Africa to the Spanish Canary Islands is attempted by many young people – often in flimsy fishing canoes.

Moustapha Diouf, a Senegalese fisher, once tried to make the voyage himself in the hope of a better life in Europe for his family. But catastrophe struck and he lost several friends on the way, and he was eventually repatriated.

Now back in Dakar, he is trying to persuade young fishers not to make the same journey, helping them instead to set up small businesses. But with fish stocks dwindling as a result of European trawlers operating off Senegal's coast, work has evaporated and many are increasingly desperate, with more and more choosing to risk it all for the chance of a better life.
