Global development podcast: are we on the brink of a new global food crisis?

France has made food a priority of its presidency of both the G8 and G20 this year. Oxfam is launching a new international campaign to create a fairer global food system. But faced with a problem this big, where do you start?

In this week's Guardian Focus podcast, Madeleine Bunting takes a look at what needs to be done to stop millions more people going hungry. She looks at India, where more than a quarter of the world's hungry people live and where the government is working on a new national food security bill, and examines the role of smallholder farmers. She asks what grassroots communities around the world are already doing to address the issues of food security.

Felicity Lawrence, special correspondent at the Guardian, joins the podcast to talk about the human cost of hunger following her visit to Central and Latin America.

To discuss strategies for the future, Bunting is joined in the studio by the chief executive of Oxfam GB, Barbara Stocking, the Oxford professor and chairman of the expert committee behind the Foresight Global Food and Farming report, Charles Godfray, and the economist and professor at New Delhi's Jawaharlal Nehru University, Jayati Ghosh.
