But isn't the point of fighting desertifaction that since there is more shade, there's less evaporation and the little water that drops there accumulates in the soil supporting more vegetation and kicking off a virtuous cycle ? (I am no expert but that's what I assumed looking at counter-desertification projects)

Shade can be an important piece of it, but evapotranspiration (evaporation through the leaves) is responsible for 7-10 degrees of cooling in a normal environment. In a hot dry place probably even more. I think this is one of those "if the whole area is green, you get great effects. But that doesn't mean planting a garden in the desert does the same thing."
