China buried straw in the desert, and for years almost everyone assumed it was a waste of effort. Dry wheat stalks against dunes that walk a few meters every year? It sounded like a joke. Seventy years later, that joke is growing leaves.

In this video I go back to the dunes near Zhongwei, where a brand-new railway in the 1950s was about to be buried by the Tengger Desert, and a small research station had to find a fix with almost no money. What they settled on looks almost silly from the air: a grid of little straw squares. But why one meter wide? And why was the straw supposed to rot away?

From there, the same humble idea travels much farther than you would expect, all the way to the edge of the Taklamakan, the desert people call the sea of death. Not everything went to plan, though. Dead tree plantations and orange skies over Beijing are part of this story too, and I did not want to leave them out.

So is this a lasting fix or a beautiful patch on a much bigger problem? Watch to the end, tell me your verdict in the comments, and subscribe if you love low-tech ideas beating high-tech problems.
