Core Insights - China's desertification and land degradation are continuously decreasing, with the "Three-North" project achieving over 20 million acres of comprehensive desertification management, leading the world in achieving zero growth in land degradation by 2030 [1][7]. Group 1: Desertification and Land Management - China's desertified land covers 25.7 million hectares, accounting for 27% of the national territory, primarily located in the northwest, northeast, and north China [4]. - The area of sandy land has been consistently decreasing, with an average reduction of 670,000 hectares per year, a significant change from an average annual expansion of 340,000 hectares at the end of the last century [4]. - The total soil erosion from China's eight major deserts and four major sandy areas has decreased by approximately 40% since 2000, with average vegetation coverage reaching 20.22%, an increase of 2.6% over the past decade [4]. Group 2: Economic Impact and Industry Development - The development of high-quality forage, economic forestry, medicinal herbs, and desert tourism in sandy areas has led to an annual production of 48 million tons of dry and fresh fruit, accounting for about one-quarter of the national total, with a total annual output value of 120 billion yuan [10]. - The "Three-North" project has transformed key management areas from "sand encroaching on people" to "green reclaiming sand," marking a historic shift in land management practices [7]. Group 3: International Cooperation - China actively fulfills its commitments under the United Nations Convention to Combat Desertification, establishing cooperation centers with Arab, Mongolian, and Central Asian countries, and setting up desertification demonstration bases in Mongolia, Central Asia, and Africa [13].
