On this week's episode of ClimateCast with Tom Heap, we're talking about land, and how our demands of it have exploded. We don’t have much spare in the UK – we need to grow food, nurture wildlife, house a growing population, and now, with a focus on climate change, create green energy, including solar farms.This week Tom Heap visits Oxfordshire, to a site that could become the UK's largest solar farm. He speaks to those for and against the development as well as also visiting a neighbouring solar farm, which does more than just generate electricity.Plus in the studio he's joined by Lydia Collas, from the Green Alliance, who explains how the UK needs to take a multi-functional approach to land use if it wants to reach net-zero.Producer: Emma Rae WoodhouseEditor: Paul Stanworth
