Those are the countries. It will be drought-resistant species, mostly acacias. And this is a brilliant idea you have no idea oh my Christ This will create so many jobs and regenerate so many communities and aaaaaahhhhhhh more info here: http://en.wikipedia.org/wiki/Great_Green_Wall it’s already happening, and already having positive effects. this is wonderful, why have i not heard of this before? i’m so happy! Oh yes, acacia trees. They fix nitrogen and improve soil quality. And, to make things fun, the species they’re using practices “reverse leaf phenology.” The trees go dormant in the rainy season and then grow their leaves again in the dry season. This means you can plant crops under the trees, in that nitrogen-rich soil, and the trees don’t compete for light because they don’t have any leaves on. And then in the dry season, you harvest the leaves and feed them to your cows. Crops grown under acacia trees have better yield than those grown without them. Considerably better. So, this isn’t just about stopping the advancement of the Sahara - it’s also about improving food security for the entire sub-Saharan belt and possibly reclaiming some of the desert as productive land. Of course, before the “green revolution,” the farmers knew to plant acacia trees - it’s a traditional practice that they were convinced to abandon in favor of “more reliable” artificial fertilizers (that caused soil degradation, soil erosion, etc). This is why you listen to the people who, you know, have lived with and on land for centuries. ^ The bold. : 12 African nations have come together pledging to build a 9 mile wide band of trees that will stretch all the way across Africa, 4750 miles, in order to stop the progressive advancement of the Sahara.

A three-million-year-old fossil of a toddler-aged hominid, Australopithecus afarensis, reveals children could walk upright as well as climb trees. A report published by 'Science Advances' looked at a thumb-sized fossilized foot from the partial remains of a two-and-a-half year old female named “Selam” found in the Dikika region of Ethiopia. According to Dartmouth College’s Jeremy DeSilva, “This foot is very human-like and indicates that the Dikika child was walking on two legs … However, the bone at the base of our big toe—called the medial cuneiform—has a connection for the big toe that is more curved and slightly more angled than what is found in humans today. Such a curved surface would allow motion of that big toe—which modern apes use for grasping. We conclude from this, and from previous studies on the shoulders of the Dikika child, that she would have been able to climb, and to also grasp onto her mother during travel.” 📷 Zeray Alemseged fossil oldschool science: A three-million-year-old fossil of a toddler-aged hominid, Australopithecus afarensis, reveals children could walk upright as well as climb trees.
