Nowdays African countries fight against sand in Sahara.
Last summer 11 African countries held a meeting in theme "how to construct the Green Wall in Sahara". The main goal was the stopping of Sahara spreading. Action would be important because there is a real danger that in 2025 Sahara will overwhelm agricultural lands.
The main concept of such a green wall would be the establishment of 15 km forest to stop sand hurricanes.
