A 5,000-mile wall of trees planted across Africa could help hold back the Sahara Desert. Environmentalist Sarah Toumi, who fights desertification in Tunisia, supports the project and says communities are key to its success CallToEarth PerpetualPlanet

The world's largest desert is growing. In the last century, the Sahara Desert expanded by more than 10%, now covering an area of more than 3.3 million square miles and spanning 11 countries in the north of Africa.

The Sahel region, a semi-arid belt that acts as a buffer zone just south of the desert, is most affected. Water, already scarce, is becoming scarcer. Soil quality is deteriorating, and a lack of vegetation is leading to food insecurity. The UN estimates roughly 135 million people who depend on these degraded lands are at risk.But an ambitious plan, launched by the African Union in 2007, could help to hold back the hot sands and protect the Sahel communities.

Africa's Great Green Wall plans to bring life to the desert 04:17Toumi speaks from her own experience after founding an organization called Acacias for All, which aims to restore land affected by desertification in Tunisia. The organization has planted more than 700,000 acacia trees in the region, she says. Bringing communities into the initiative and demonstrating the value of restoration has been vital to the sustainability of the project.

I guess when you can't obsess over the pres you have to resort to articles about trees and Louis Vuitton bags shaped like airplanes. Out of all the bs msm news networks CNN is by far the best to laugh at. Don't worry though only 3 years until you get to cry about him again.

I thought because of all the carbon dioxide in the air and warmer climate, the Sahara was actually turning back into a green vegatative state?

That's 'natural' - also practiced in Bhutan -, similarly like rebuilding mangrove swamps (Bangladesh) being natural defence system against the sea/tsunamis (and nurseries for fish) Simple conservation method, also storing CO2 When worldwide applied: Climate disaster mitigation

the sahara used to be a lush grassland 10,000 years ago

Yeah walls!

So nice action planting 5,000 mile wall of trees to hold back the Sahara Desert.
