Sheila Dillon hears from some of the world's disappearing food tribes and finds out why efforts are underway to preserve indigenous food cultures in north America, Scandinavia and in Scotland's Highlands and Islands.

She travels to Turin for Terra Madre, the biennial gathering of food communities, farmers, fishermen and cooks organised by the international Slow Food movement. Among the 6,000 delegates - who'd travelled from 160 countries - are people from indigenous communities like the Sami, nomadic arctic reindeer herders as well as native American rice harvesters, the Ojibwe.

Scientists, agriculturalists and nutritionists are now taking more interest in these traditional cultures seeing them as valuable models of sustainable food production and offering fresh insights into human diets.

But many of these food cultures are under threat because of disputes over land rights, prejudice and climate change and so work is underway to understand, document and support these communities. Sheila meets the people involved in making this happen.
