The Intergovernmental Panel on Climate Change has published its report looking at mitigating the impact of a warming climate, and the role agriculture will have to play to secure all our futures. It points out that global greenhouse gas emissions must peak in just three years’ time, and then reduce by 43 percent by 2030. And it highlights that methane - a major emission from livestock farming - would need to be reduced by a third by the same time. We speak to the lead author in charge of the report's agricultural chapter, Professor Jo House, about how crucial land use management is in a global climate challenge. And hear what the Nature Friendly Farming Network think about the report. All this week we're talking about leaving farming and with the government offering a lump sum to farmers to leave the industry, to allow the next generation to take up the reins, we hear from arable farmer Henry DuVal about his own succession planning. After realising he couldn't continue to support three generations unless things changed, Henry enlisted his son Ed to take on the family farm. They decided to set up a bio-gas plant, where instead of growing crops for food, their fields are now producing fuel for anaerobic digestion and much of the methane they produce goes into the gas grid or makes electricity.
