One of the most unique large-scale international climate change projects is underway in Africa. A 4,000 mile “wall of trees” is being constructed across the east-west axis of the continent as a defense against rapid, expanding desertification of the Sahara.
11 nations — Mauritania, Senegal, Mali, Burkina Faso, Niger, Nigeria, Chad, Sudan, Ethiopia, Eritrea, and Djibouti — have agreed to participate in The Great Green Wall initiative (GGW), planting a contiguous “wall of trees” stretching 4,300 miles long and 9 miles wide, across the entire width of the African continent from Djibouti in the east to Senegal on the west.
The project was approved by the African Union in 2007, under the umbrella of the Community of the Sahel-Saharan States (CEN-SAD). In 2008, the first trees were planted along the wall’s path.
Progress (and reporting) currently varies from nation to nation; the process is still in its infancy and will take several years to complete. Nevertheless, the project is already showing some success: a World Food Program (WFP) report from Senegal details how villages in Widou Thiengoli are now harvesting fresh fruits and vegetables from the dry desert sands, a by-product of the Wall initiative. Some 50,000 acres of trees have already been planted in Senegal, according to press reports.
Desertification has emerged as a “major planetary threat” with particularly daunting challenges for Africa. Climate change has led to prolonged periods of drought and other symptoms of desertification, which are being experienced by a growing number of countries. The UN Food and Agriculture Organization (FAO) reports that two-thirds of the African continent is classified as desert or dry lands. Rainy seasons and other weather patterns — long consistent — are now changing across the region. In Senegal, for example, the rainy season now begins in September — it traditionally started in July.
The UN estimates that two-thirds of Africa’s arable land could be lost by 2025 if this trend continues.
“People used to go to towns to seek paid work during the lean season, but since the project started, that has changed,” says Papa Sarr, Technical Director of the Senegal National Agency of the Great Green Wall.
The Green Wall, said Apel, “is off to a promising start.” Standing near a row of waist-high trees in Widou village — one of Senegal’s Green Wall locations — he said: “In 10 to 15 years this will be a forest. The trees will be big and this region will be completely transformed.”
This is a great project! many thanks to those who are undertaking this massive work. Also the first time I’ve heard of this. I’m wondering what effect this will have on hurricanes. Are they not begun by the winds blowing off the west coast of Africa? And what effect this will have on the Amazon. I seem to remember a documentary stating that the desert winds carried soil particulates (dust) across the Atlantic and depositing it on the Amazon basin, renewing the depleted soil on the forest floor.

With all of the warring going on in this region, particularly in Eritrea, Sudan and Mali, this is not just a climate initiative or an engineering feat, it is also a peace initiative.
For these countries to succeed at this, they HAVE to (literally) cast their swords into plowshares, and I think that’s wonderful.

Thanks yet again, Don; This has generated a lot of buzz– Lots more needed.
-until other countries follow suit.
Right off the bat, this readily lends itself to general consumption, given no high level of tech or political savvy needed. -so, perfectly understood at once by young’uns and,well, anyone. In that spirit, I’m sharing this with my middle school students, among others.
Middle-school students? ..so nice to know teachers are exposing this issue to young students….climate change will effect them and their world far more than it will effect the apathetic robber-barons behind the global fossil fuel industries. Thank you for being such a conscientious educator. When your students are just a little older, they will be of age to make choices and affect change on their terms. Teach on…..

Truly inspiring. As with so many things, I had not heard about this before, even though it’s been happening for many years. Similarly, most people I speak with have never heard of the incredible research done into the phenomenon called “Global Dimming” wherein pollution (not greenhouse gases, but particulate pollution) is literally blocking the sun and thus lowering temperatures and altering evaporation patterns in certain geographic areas. NOVA broadcast an episode in 2006 called “Dimming the Sun” in which a very strong case is made for how “Global Dimming” is more to blame for the Sub-Saharan drought than greenhouse gas induced “Global Warming.” Still man-made, but of a very different sort. The coal and other industrial pollutants drifting southwest from India and China obscure the sun over the western Indian Ocean and prevent the normal creation of monsoon conditions through evaporation. A multi-million dollar scientific study was conducted over the course of many years to investigate this. So, bringing the rain back to the Sahara could possibly be accomplished through strict particulate pollution controls in India a China. In this case, curbing greenhouse case emissions may be, while not irrelevant, at least less significant. I feel that we need to keep our perspective broad and our minds receptive to new information in order to most effectively address the complicated challenges created by human activity (hyper-activity) on planet earth.
Yeah, that is a very undiscussed subject. We did cover it. I thought it was fascinating. http://planetsave.com/2010/12/20/global-dimming-video/
The troubling thing is, as these pollutants are reduced, the world will warm even faster than it has been. yikes.
aha, but it seems this trend reversed in 1991 or so: http://en.wikipedia.org/wiki/Global_dimming

People
all over the world, worrying about the effect of desertification, are
attentively looking for success stories in the combat of land
degradation. This Great Green Wall project could bring significant good
news about the possibilities to make progress. Taking into account
that 50.000 acres have been successfully planted in Senegal, this
“success storiy” merits to be fully illustrated (field photos, aerial
photos, satellite photos).
I
am looking forward to see these fantastic documents and I am eagerly
looking for the “lessons learned” in Senegal, which would be very
profitable for the other 10 countries involved.

If they can do it, “we” can do it!!!!!!!

So inspiring! Thank you, thank you, thank you for this wonderful news!
Diane,
One of the things that keeps me from being really desolate about all this is to see that others express inspiration that someone’s keeping it out there… So thanks to you, and thanks to the author of the article. I personally haven’t gotten any really impressive responses from our representatives– but feel better being a part of a larger group that cares!
