"If the customer is willing to pay the price, we have produce available." - Philippe Appeltans, CEO of the Belgian salad and fruit co-operative, BelOrta. In this programme Charlotte Smith has an in-depth chat with Philippe about how growing and selling on the continent compares to the UK. It comes as salad shortages continue on supermarket shelves here - blamed by retailers on bad weather in Morocco and Spain and by growers on retailers refusal to pay a realistic price for home grown produce. And can tech solve tail biting in pigs? We visit a research farm at Scotland's Rural College. Presented by Charlotte Smith Produced for BBC Audio in Bristol by Heather Simons
