Pavlov to Plant Breeding: Food Prizes that Changed the World.

From Nobel winners to great innovators, Dan Saladino explores the history of prize-winning food ideas that changed the world, including researchers who uncovered the secrets of our stomachs to the plant breeds transforming the future of wheat.Nominations are now open for this year's BBC Food and Farming Awards until June 19th, including Best Innovation which was created to celebrate ideas that will make food production better for us and for the planet.For more than a century, and around the world, ground-breaking ideas linked to food have featured in awards and prizes, from Ivan Pavlov's research on our digestive system through to Norman Borlaug's efforts to increase food production with crop breeding in the 1960s. Both received a Nobel Prize. In more recent years awards have been created to find solutions to some of the biggest challenges we face in food and farming. The former chef of the Swedish restaurant Faviken, Magnus Nilsson now oversees the Food Planet Prize, the world's biggest environmental prize. He tells Dan about previous winners who have created solutions to plastics in our oceans and the problem of abandoned fishing equipment, so called 'ghost nets' and also a project in Africa providing refrigeration to farmers which is resulting in a dramatic reduction in food waste.Another award winner in the programme is Heidi Kuhn, founder of Roots of Peace. This year she was recognised by the US based World Food Prize for decades of work helping to clear mines from regions impacted by conflict and return the land to food production. Produced and presented by Dan Saladino.
