Core Viewpoint - The Alxa League is committed to establishing a northern demonstration base for desertification prevention and control, focusing on comprehensive management of desertified land in the region where the Badain Jaran and Tengger deserts meet, aiming to strengthen ecological security in northern China [1][2][3]. Group 1: Project Overview - The Jiukoshu desertification control project has completed a management area of 418,300 acres, including 140,400 acres of artificial afforestation and grass planting, and 125,300 acres of engineering sand fixation [1]. - The Alxa League plans to complete a total ecological construction task of 3,253,500 acres by 2024, with a focus on the "He-Ta" area, which includes 9 key projects with an investment of 3.085 billion yuan [2][3]. - By 2025, the league aims to fill the gaps in desert edge protection and implement targeted management measures for different desert overflow areas [2][3]. Group 2: Collaborative Efforts - The Alxa League emphasizes joint prevention and control, forming a collaborative governance model with neighboring regions, and has established deep ecological governance cooperation mechanisms with areas like Wuwei City in Gansu Province [3][4]. - The league is implementing 7 joint prevention and control projects in the Mongolian-Gansu border area, with a construction task of 1,188,700 acres [4]. Group 3: Economic and Social Impact - The league promotes a model of "work for relief" to engage local farmers and herders in project construction, successfully employing over 15,454 laborers [4]. - The ecological construction is expected to enhance local livelihoods, with over 800 households benefiting from the development of specialty sand industries, leading to an annual income increase of 20,000 to 50,000 yuan per person [6]. Group 4: Future Plans - The Alxa League aims to further develop a connection mechanism involving government guidance, enterprise leadership, and local participation to enhance cross-border joint prevention and control efforts [6]. - The league is determined to accelerate project construction to support green development and contribute to ecological security in northern China [6].

Core Viewpoint - The "Three North" project is a significant national strategy aimed at combating desertification and improving ecological conditions in northern China, with a focus on high-quality development and integrated management of natural resources [1][4]. Group 1: Project Overview - The "Three North" project, initiated in 1978, targets areas severely affected by desertification, with a total planned area of 4.069 million square kilometers across 13 provinces and regions [2][3]. - The project aims to increase forest coverage from 5.05% in 1978 to 14.95% by 2050, while effectively controlling sand hazards and soil erosion [2]. Group 2: Phased Development - The project has been implemented in phases, with the first phase (1978-1985) focusing on agricultural ecological barriers and achieving afforestation of 5.35 million hectares [3]. - Subsequent phases have progressively expanded the scope and objectives, culminating in the completion of 31.74 million hectares of afforestation by 2020, raising forest coverage to 13.84% [3]. Group 3: Current Phase and Goals - The current sixth phase (2021-2030) emphasizes consolidating and expanding achievements in sand control, with a focus on integrated protection of mountains, rivers, forests, fields, lakes, grasslands, and deserts [4][5]. - Key battles include the Yellow River "bending" campaign and the eradication of sand hazards in specific regions, supported by a coordinated governance mechanism [4][5]. Group 4: Technological Advancements - The project has seen a shift towards mechanized sand control, with nearly 50% of operations now utilizing advanced machinery, significantly improving efficiency and reducing costs [6][8]. - Innovations in technology, such as the "Linji Cloud" system for equipment monitoring, have enhanced operational management and effectiveness [7]. Group 5: Economic Integration - The project has successfully integrated ecological restoration with economic development, promoting sustainable agricultural practices and the cultivation of drought-resistant crops [11][12]. - For instance, the development of the goji berry industry in Ningxia has created a complete industrial chain, contributing to a total output value of 29 billion yuan [14]. Group 6: Regional Practices - Inner Mongolia has implemented various innovative models for sand control, achieving significant ecological improvements and economic benefits through community involvement and technological integration [17][21]. - The region has seen a transformation from "sand encroachment" to "green recovery," with substantial increases in vegetation cover and economic output from ecological industries [19][20].
