Can a 4,000-mile wall of trees stop Sahara Desert's drift? - CSMonitor.com: "The initiative plans to strategically plant swaths of trees roughly nine miles wide and over 4,000 miles long.

The central idea is for this belt of forest to serve as a barrier against desert winds and thus revitalize soil to protect against land degradation."

"Mongolia and China began similar efforts to combat the encroachment of the Gobi Desert in 2006. Furthermore, President Franklin Roosevelt initiated successful Shelterbelt programs in the 1930s, using strategic planting of foliage to combat the land degradation caused by the Dust Bowl on the American high plains.

The Shelterbelt initiative, however, was successful because it supplemented its “green wall” policies with monetary incentives for farmers who changed their techniques to more ecologically sound production methods."
