Jean-Marc Sinnassamy is a senior environmental specialist with the Global Environment Facility (GEF). He helps manage a program developed under the Great Green Wall initiative with countries in the Sahel and West Africa. The GEF has been with the initiative since the beginning, helping to convene country leaders at the headquarters of the United Nations Convention to Combat Desertification in Bonn, Germany, in February 2011. The World Bank and other organizations focused on global development and the environment provide financial and technical support. Drawn in Winkel Tripel projection with distortions minimized unlike other World maps (e.g. Greenland is shown the same size as Argentina, not South America)

We wonder about the builders, the soldiers who were stationed at some of these lonely outposts, the nearby villagers who may or may not have appreciated the garrisons near them,” says Jennifer Ambrose, who lives with her family north of Beijing and visits the Great Wall several times a month. “We explore around the wall, surprised to find remains of older walls that predate the Ming by centuries.” The one thing most people “know” about the Great Wall of China—that it is one of the only man-made structures visible from space—is not actually true. Since the wall looks a lot like the stone and soil that surround it, it is difficult to discern with the human eye even from low Earth orbit, and is difficult to make out in most orbital photos. However, this does not detract from the wonder of this astounding ancient structure. While trees and forests are only part of the focus of the Great Green Wall initiative, many in the media have cast the project as solely a tree-planting project and an attempt to halt the southward expansion of the Sahara Desert.In the end, Sinnassamy hopes the region as a whole will be composed of a “ mosaic of landscapes” that increases biodiversity and maintains native flora as part of agricultural land. Each participating country has its own individual goals, which include reducing erosion, diversifying income, increasing crop yield, and improving soil fertility. Meticulously researched using multiple authoritative sources including the U.N., U.S. Board on Geographic Names, and policies of individual governments. In Africa, scientists are hard at work restoring land once rich with biodiversity and vegetation. Eleven countries in the Sahel-Sahara region—Djibouti, Eritrea, Ethiopia, Sudan, Chad, Niger, Nigeria, Mali, Burkina Faso, Mauritania, and Senegal—have joined to combat land degradation and restore native plant life to the landscape. Because the walls were defensive structures, you can learn about building and engineering skills throughout ancient China as well as its military history and strategies,” Ng says. Expertly researched and designed, National Geographic's World Wall Map is the authoritative map of the world by which other reference maps are measured.

Insider Tip: The Great Wall was designed for protection, but don’t forget the forts that were another part of China’s defenses. The 16th-century Yaoziyu Fort, for example, is the best preserved of Huanghuacheng’s six forts. Changyucheng Village was founded 500 years ago to guard one of the wall’s most important passes.The Great Wall impresses everyone who sees it for the first time, from children to adults, from the general tourists to scholars,” says Henry Ng, the manager of the World Monuments Fund’s China projects. “The vastness of the structure helps children grasp the great achievements in human history—from the Great Wall to the great pyramids—and can help inspire them to learn more about human achievements over the millennia.” This article needs additional citations for verification.

Mysteries and clues

The Seven Chinese Brothers by Margaret Mahy; illustrated by Mou-Sien Tseng (1992): This beautifully illustrated book tells the old Chinese folktale of seven brothers with extraordinary abilities, who band together and use their powers to challenge the emperor’s mistreatment of his workers on the Great Wall. Examples of success include more than 50,000 acres of trees planted in Senegal. Most of these are the acacia species Senegalia senegal, which has economic value for the commodity it produces, gum arabic. (Gum arabic is primarily used as a food additive.) A small portion of the trees are also fruit-bearing, which, when mature, will help combat the high levels of malnutrition in the country’s rural interior. Children will delight in wandering the ramparts, lined with battlements and parapets and wide enough for five horses to ride abreast. “We encourage our seven-year-old son, Myles, to explore the construction as much as he can,” Ambrose says.
