In this week's Focus podcast, we look at the issue of food security.
In September, Mozambique erupted in a series of food riots, provoked by sudden hikes in the price of bread. At least 14 people died and hundreds were injured. In 2007-08, similar rises in the cost of staple foods triggered protests all around the world.
This week, John Vidal reported that rising food prices and shortages could produce a further food crisis.
Felicity Lawrence is joined by Oxfam GB's head of research, Duncan Green to discuss the issue.
We hear from Jayati Ghosh, leading professor of economics at Jawaharlal Nehru University, in India; Raj Patel, award-winning author of The Value of Nothing, and a fellow at the Institute for Food and Development Policy, also known as Food First; and Olivier de Schutter, the UN's special rapporteur on the right to food.
