Over the past month, the ̽��ֱ�� of Cambridge has been profiling research that addresses one of the biggest challenges of the 21st century – how to guarantee enough food, fairly, for the world’s rapidly expanding population. As part of this, we asked whether you had a question that you wanted us to answer, and put them to a panel of academics who specialise in research to do with food security. Here's what they had to say. Thanks to everyone who sent questions in!
