Desertification info.

[Niremix]

So it may seem strange I'm posting this here but I've seen a lot of different people with different interests and jobs so it can't hurt since this is the inn.

I'm having a school report on desertification and I can't seem to find any projects planned or actually on the go to stop desertification. I'm wondering if someone could help me with this and link me some stuff? I have literally googled for hours but the only thing I could find was: The Big Green Wall which is the project that's going to stop desertification in the Sahel regio in Mid Africa.

Also, if desertification has positive effects. Guess not but every little info helps so if anyone coincidentally knows more about this please let me know!
