Last month, I attended a discussion meeting on food security and climate change at the Royal Society, London. As in other areas, it appears that change is going to hit those people hardest who are already in a precarious situation and can least afford to protect themselves. However, I also heard of some approaches promising efficiency improvements with very simple means, such as clever combinations of crops.
I've summarised some of the things I learned there in a feature which appears in this week's issue of Current Biology:
