China has been conducting sand control projects in Taklimakan Desert in northwest China’s Xinjiang. But how does that work? ⁣ ⁣ First, bulldozers are there to level up the sand, followed by motor graders to smoothen and compact the sandy surface. ⁣ ⁣ Then unmanned tree-planting machines guided by BeiDou Navigation Satellite System (BDS) are used for placing saplings. Each such machine can plant over 13,000 trees per day. Interplanting and drip irrigation technologies are also applied. ⁣ ⁣ Hotan Prefecture of Xinjiang plans to rehabilitate over 14 million hectares of desertified land this year. ⁣ ⁣ #reforestation #greendevelopment #China #desert
