Global climate change threatens many of the world's foods. It's a concern for Italy's celebrity chef, Carlo Cracco, who recently took a break from TV sets and high end kitchens to travel to east Morocco this month to highlight the issue.

 

Seventy-year-old farmer Fatma Abed showed Cracco how to make a regional specialty using a desert truffle called terfass. Terfass once abundant, they're now rare due to erratic weather and increasing dryness. While sheep are losing their grazing land amid the persistent arid conditions.

 

"Climate change is a fact, it is difficult to change or reverse the process, perhaps it is no longer possible. We can slow it down, but we cannot stop it. So we must help those people who work to recuperate the land, so that there is a change in the way we fight the battle of climate change," says Cracco.

 

In this battle Cracco is working with the United Nations to teach locals sustainable management of their natural resources using careful techniques to collect water or reduce soil erosion - practices to keep eastern Morocco's unique food traditions alive.
