Countries on the edge of the Sahara desert are reversing desertification by just digging half circles.
The ground in these places is too compact for water to soak in during wet season which leads to flooding but digging these holes gives the water a place to stop and soak in. And they’re pushing back the desert with this. By just digging holes.

@appassionato The only difference I spot is that the Sahel is not part of it any more, just Kenya, Tanzania and Senegal. The half moon technique I have already seen in various films on the Great Green Wall.
Don't get me wrong, I'm not making any critique of the new project, just trying to understand its relation to the one I already knew about. The absence of Sahel in particular is regrettable but quite understandable:
@ducasleo I also thought it was part of it. The half moon digging being the method used for the Great Green Wall Project and everybody kinda joining into this one big effort with smaller task forces.
We've tried this technique in Brandenburg, Germany at #ArschDerHeide on our very poor dry sandy soils. Even there you can see its impact. It is not just the water soaking in. It is also the small wind break and shade that helps young plants to sprout & establish in the semi circles.
