Each year young people from the tiny West African nation of The Gambia try to reach Europe through “The Backway” - a costly, perilous journey over land and sea.

Many do not make it. In recent years, the EU has done deals with several North African nations to clamp down on irregular migration. Though human rights groups say the treatment of migrants can be brutal - allegations the authorities deny. But each year thousands of African migrants say they have no choice but to return home.

It can be a struggle to return. Some are traumatised by their experience and face stigma for having failed to reach Europe. Others are already planning to try again.

For Crossing Continents, Alex Last travels to The Gambia to find out what happens to migrants who've risked everything to get to Europe, but end up back home.
