Jimmy Doherty's Farming Heroes - North of England

Jimmy Doherty continues his journey around Britain, meeting the people who are shaping the future of farming. He's on a search for those striking out in new and original ways that will help all of us meet the challenges of the gathering world food crisis. This week he's in the north of England, where farmers are fighting back after some tough years. To see how they've done that, he joins in on a hillside sheep round-up, harvests rhubarb by candlelight, and hacks his way through a willow forest destined to produce electricity. Finally, he pits his own rare-breed pork in a public taste-test against meat from a pig claimed to be the most modern in the world.
