Photo taken on Aug. 1, 2018 shows a seasonal river channel at the Kubuqi Desert in Erdos, north China's Inner Mongolia Autonomous Region. Kubuqi, the seventh largest desert in China, is a good example of China's success in alleviating desertification. About 6,460 square kilometers of the Kubuqi desert has been reclaimed in the last 30 years. (Xinhua/Zhang Shanchen) ?
