Desertification control team works along first desert highway in Ningxia, NW China (4)

Aerial photo taken on Sept. 7, 2020 shows desertification control workers making straw checkerboard barriers in the Tengger Desert along the construction site of the Qingtongxia-Zhongwei section of the Wuhai-Maqin highway in northwest China's Ningxia Hui Autonomous Region. The Qingtongxia-Zhongwei section of the Wuhai-Maqin highway is under construction, of which an 18-kilometer-long section going through the Tengger Desert is the first desert highway in Ningxia. A desertification control team has worked along the highway construction site, using straw checkerboard barriers and planting vegetation to stop the dunes from moving or expanding. (Xinhua/Wang Peng)
