Food-growing areas around the world face new challenges as a result of climate change. This Syria-US project highlights one potential solution: reaching deep into the history of plants

Sickle in hand, this Syrian man harvests wheat as the sun begins to fall. He stands in a field near the village of al-Bahariyah, in the eastern Ghouta region on the outskirts of the capital Damascus. Six thousand miles away in a greenhouse in Kansas, researchers watch as a cloud of Hessian flies works on destroying 20,000 trial seedlings. But one species among the samples remains untouched: an ancient Syrian grass known as Aegilops tauschii.

Seeds from this wild grass that were once stored in a seed bank in Tal Hadya, 25 miles west of the largely destroyed city of Aleppo, have made their way to the US. As temperatures rise, pests and diseases are moving north into America’s cereal and grain heartland, diminishing yields and sometimes decimating crops. Smuggled out of Syria as the bombs fell, Aegilops tauschii seeds could now help US wheat survive the hotter and drier conditions triggered by climate change. Today’s domesticated wheat originated from Syria and neighbouring countries in the ‘fertile crescent’. So it stands to reason that the seeds stored there are embedded with survival strategies developed over thousands of years.
