Arsene Sourabi works for a company in Burkina Faso producing dried mango, which is then sold under the Fairtrade labeling system. This guarantees that supermarkets and consumers in rich countries pay a fair price for the goods.

Burkina Faso has one of the lowest average incomes in the world, with the average person earning just over £600 a year, but Fairtrade offers people the chance to trade their way out of poverty.

Arsene told his audiences: "Fairtrade is the kind of aid to end all aid.”
