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. Thousands of place names carefully and artfully placed to maintain legibility in heavily populated areas

Find sources: "List of walls"– news · newspapers · books · scholar · JSTOR ( January 2015) ( Learn how and when to remove this template message) 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.” 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.
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. We are not fighting the desert,” he says. “In the majority of the areas we are working in these 11 countries, the desert is not advancing. The [Sahara] Desert is a very stable ecosystem. Of course, there are some areas on the margins—for instance in Senegal, Mauritania, and Nigeria—where there are some sand movements. But from a geographic perspective, over time the desert has been relatively stable in this area.” Behind the name or the brand ‘Great Green Wall,’ different people see different things. Some people saw just a stripe of trees from east to west, but that has never been our vision,” he says. “In Niger, Mali, and Burkina Faso . . . natural regeneration managed by farmers has yielded great results. We want to replicate and scale up these achievements across the region. It’s very possible to restore trees to a landscape and to restore agroforestry practices without planting any trees. This is also a sustainable way of regenerating agroforestry and parkland.”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. Accurate place names use a combination of conventional English names, official national names, and standard transliterations for non-Latin alphabets. 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.” Expertly researched and designed, National Geographic's World Wall Map is the authoritative map of the world by which other reference maps are measured. Zhu Yuanzhang, who became the Hongwu Emperor, took power in 1368 C.E. He founded the Ming Dynasty, famous for its achievements in the arts of ceramics and painting. The Ming emperors improved the wall with watchtowers and platforms. Most of the familiar images of the wall show Ming-era construction in the stone. Depending on how the wall is measured, it stretches somewhere between 4,000 and 5,500 kilometers (2,500 and 3,400 miles).
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. Corner inset maps feature vegetation, land use, population density, and north and south polar regions
