The UN estimates that global food production will have to increase by 50% by 2030 to meet the needs of the growing population. It's expected to reach 9 billion in 20 years. At the Oxford Farming Conference UK and European leaders, farmers and scientists have been discussing how farmers can increase yields with restricted energy, water and other resources. Sarah Swadling asks with increased pressure to reduce subsidies how farmers will do this. She visits a Shropshire dairy farm to see what's being done to get more output from fewer inputs and if they could go further.

Presented by Sarah Swadling and produced by Anne-Marie Bullock.
