Farming Today meets the farmers toiling on the land where fields meet the sea and discovers the challenges they face from the elements. Anna Hill gathers wild samphire on the north Norfolk coast with chef Chris Coubrough and meets farmers constantly at odds with the rising tide in the Norfolk Broads. Sarah Falkingham meets a farmer whose land is perched precariously on a cliff overlooking the North Sea. Presented by Anna Hill and produced by Martin Poyntz-Roberts.
