05/01/23 - The Oxford Farming Conferences

As hundreds of farmers gather together in Oxford, we report from the two farming conferences. From the progress of the agroecological movement to revolution in global food chains - the conferences will tackle some big topics. We hear from farmers and focus on the idea of green finance - is it a great business opportunity or a risky gold rush? Presented by Anna Hill Produced for BBC Audio by Heather Simons
