Farmers in Australia are used to hot weather and droughts, but they've had a whole series of extreme weather events to contend with lately - including widespread flooding. Anna Hill talks to a spokesman from the National Farmers' Federation in Australia, who explains how the situation there is contributing to the global food supply crisis. Meanwhile the UK's National Drought Group met yesterday. With predictions that by 2050 some rivers could contain between 50 and 80 per cent less water during the summer months, how should farmers be managing their water supplies in the longer term? And we meet the "Pint-Sized Farmer" - who's been using social media to open up a new window on the farming world. Presented by Anna Hill and produced in Bristol by Emma Campbell.
