A tree is lifted with a crane before being placed on a truck at Toudunying state-owned commercial forest estate in a village near the edge of the Gobi desert, on the outskirts of Wuwei, Gansu province, China, April 16, 2021. Over the last four decades, the Three-North Shelter Forest Programme tree-planting scheme, known colloquially as the "Great Green Wall", has helped raise total forest coverage to nearly a quarter of China's total area, up from less than 10% in 1949. In Hongshui trees have become a major part of the local economy and the area is dominated by a large state-owned commercial forest estate called Toudunying.
