Core Viewpoint - The prevention of desertification is a significant ecological issue affecting human survival and development, emphasized by the Chinese leadership as crucial for ecological security, national strength, and sustainable development of the Chinese nation [1][2]. Group 1: Importance of Desertification Prevention - The situation regarding desertification and sand control in China remains severe, particularly in the "Three North" regions, which are economically underdeveloped and home to ethnic minorities [2]. - Historical experiences highlight the consequences of ecological degradation, with past desert expansions leading to the loss of significant cultural and economic areas, underscoring the need for proactive measures [3]. Group 2: Achievements and Strategies - Since the implementation of the "Three North" shelterbelt program initiated in 1978, China has made remarkable progress in combating desertification, achieving a historic shift from "sand encroaching on land" to "green reclaiming sand" [4]. - The leadership acknowledges the importance of sustained efforts and the need for a long-term commitment to desertification prevention, recognizing it as a challenging and ongoing process [5]. Group 3: Future Directions - The goal is to create new miracles in desertification prevention by adopting a systematic approach that integrates various ecological elements for comprehensive management [8]. - Successful examples of integrated management, such as in Inner Mongolia and Gansu, demonstrate the effectiveness of coordinated efforts in restoring ecological balance [9]. Group 4: Scientific Approach - A scientific approach to desertification control is emphasized, advocating for research-based planning and the appropriate use of resources to ensure effective outcomes [10]. - The focus is on adapting strategies to local conditions, utilizing suitable vegetation types, and avoiding impractical interventions in areas unsuitable for transformation [10].

Core Viewpoint - The "Three-North" project is a significant national strategy aimed at combating desertification and enhancing ecological restoration in China's ecologically fragile regions, with a focus on systematic governance and integrated ecological protection [10]. Group 1: "Three-North" Project Overview - The "Three-North" project is positioned as a critical initiative for ecological protection and restoration in China's desertification-prone areas, emphasizing the need for a comprehensive approach to environmental management [10]. - The project aims to complete the governance of over 3.8 million hectares by 2024, marking a substantial step in ecological restoration efforts [10]. Group 2: Local Implementation and Innovations - In the Yellow River "Z" bend area, a systematic approach to sand control has been established, integrating natural protection areas, farmland shelterbelts, and designated zones for sand fixation and solar energy [2][3]. - In the Khorchin Sandy Land, innovative practices such as intercropping drought-resistant tree species have been implemented to enhance the resilience of afforestation efforts [6][7]. - The integration of solar energy projects with agricultural practices has transformed previously barren lands into productive areas, demonstrating the synergy between ecological restoration and economic development [7]. Group 3: Community Involvement and Economic Benefits - The local communities are actively engaged in sand control efforts, with policies facilitating the allocation of state-owned sandy lands to households for cultivation, thereby promoting both ecological and economic benefits [9]. - The production of desert plants like meat苁蓉 has surged, with the region accounting for 85% of the national output, showcasing the successful combination of ecological restoration and economic growth [9].
