Mass tree planting in China is turning one of the world’s largest and driest deserts into a carbon sink, meaning it absorbs more carbon from the atmosphere than it emits, new research reveals.

The Taklamakan Desert (also spelled Taklimakan or Takla Makan) is slightly larger than Montana, stretching across about 130,000 square miles (337,000 square kilometers). It is encircled by high mountains, which block moist air from reaching the desert for most of the year, creating extremely arid conditions that are too harsh for most plants.

However, over the past few decades, China has sowed a forest around the Taklamakan’s edges, and a new study suggests this approach is beginning to bear fruit.

This is good news and all but I’m a little hazy on what’s happening here. It seems like the desertification of surrounding areas has stopped?

Last sentence sums up the answer to your question:

The Great Green Wall’s potential to slow desertification remains unclear, but its role as a carbon sink “may serve as a valuable model for other desert regions,” he added.
