The Great Wall of Africa?
Problem: Desertification (when viable land is encroached upon by desert) threatens the lives of millions of people in Africa. Solution: Build a wall to keep the desert from spreading. According to architect Magnus Larson, it is not as difficult as you might imagine. Take sand dunes at the edge of the desert, combine them with a mixture of water and bacteria, let dry and you've got an instant sandstone wall! Read all about it at BBC news.

You mean the global warming that has the Earth cooling down now for over a decade?
If I understand it correctly the desert is just reclaiming it's own.
