China has a lot of reforestation projects, the most notable of which is the "Green Great Wall," which is intended to hinder the growth of the Gobi dessert. The benefits of this project are questionable because the trees soak up a lot of groundwater in an already very arid area. Also, the forests rely on a few species of trees, so it's very vulnerable to disease.

I had seen a video somewhere that the Green Great Wall was failing and in constant threat of collapse because of the arid wind and pretty much non-existent water table causing the trees to die off faster than they can be planted.

The footage had interviews with a group that tries to keep it watered.

EDIT: It might have been the initiative in Africa (Sahara). I tried finding the video and am met with similar initiatives on both continents.
