With tinder-dry conditions in many parts of country, fires in farm machinery are at record levels. The insurer NFU Mutual is recording two a day on average - which means that numbers are up by 35%. We hear from a farmer in Buckinghamshire who experienced a combine harvester fire first-hand this week. Caz Graham asks the Farm Safety Foundation what farmers can do to reduce the risk of a blaze. As temperatures rise and our climate changes, experts are warning that the way we grow our food will have to change too. We visit the Allerton Project - a demonstration farm in Leicestershire, where they're researching what that might look like. Continuing a week-long look at this year's harvest, we're out in Lincolnshire with the pea viners. Presented by Caz Graham and produced by Emma Campbell
