Why Is Africa Feeding Us?

Dan Saladino and reporter Jack Thompson investigate the UK's growing dependence on two farms in northern Senegal based around a lake. In recent years they have become the source of most of the sweetcorn, radishes and beans sold by supermarkets. Is this a good arrangement for the UK and the Senegalese or a risk to food security in both countries? Produced and presented by Dan Saladino. Reporting from Senegal, Jack Thompson.
