Do food security experts have their own emergency supplies?

The Food Chain asks three top food security experts whether they keep a few weeks' worth of extra food in their kitchen cupboards, just in case of a food shortage. How confident are they really about the world's food supply? We speak to professor Tim Benton, Strategic Research Dean at University of Leeds and Fellow at Chatham House; Tracey Allen, Commodities Analyst at J.P. Morgan; and Corinne Fleischer, Director of the Supply Chain at the World Food Programme.
