Core Viewpoint - The article highlights the long-term efforts of a family in Gansu Province, China, who have dedicated over two decades to combating desertification and successfully afforested more than 10,000 acres of land in the Tengger Desert area, showcasing resilience and commitment to environmental restoration [1][5][7] Group 1: Family's Journey and Challenges - The family, led by Wang Tianchang and his son Wang Yinjie, began their afforestation efforts in 1999 in response to severe sandstorms threatening their farmland [1][2] - The tragic loss of Wang Yinjie's 14-year-old son in 2005 due to illness became a driving force for the family, as his last words inspired them to continue their fight against the desert [1][2][3] - The family faced numerous hardships, including living in a makeshift underground dwelling and dealing with the physical toll of their labor over the years [2][3] Group 2: Achievements in Afforestation - The family has successfully established a survival rate of around 70% for the saplings planted in the desert, including species like Haloxylon ammodendron and various trees [2][3] - By 2010, Wang Yinjie set a goal to afforest 10,000 acres, which was achieved last year, and they aim to double this figure in the future [5][6] - The family has mobilized community support, with over 80 volunteers assisting in their recent afforestation efforts [6] Group 3: Environmental Impact - The family's efforts have led to the establishment of a 12-kilometer shelterbelt, with over 1.5 million saplings surviving and a significant increase in local biodiversity, including an increase in bird species from 12 to 89 [7] - The area has seen a reduction in sandstorm days from an average of 37 to 9 annually, demonstrating the effectiveness of their afforestation initiatives [7]

Core Viewpoint - The "Million Forest Plan - Desert Locking Forest Action" has successfully planted over 10 million trees and restored 1.1 million square meters of desert land in the Tengger Desert area from 2014 to 2023, showcasing significant ecological restoration efforts [1][2][4]. Group 1: Project Achievements - The project has resulted in the planting of over 10 million trees, covering approximately 16.3 million acres, equivalent to 15,219 standard football fields [1][2]. - The average rate of tree planting has been 2 trees per minute, and about 3.9 square meters of desert land has been reclaimed every second [2][3]. - The project has effectively created a green barrier to prevent desert expansion and reduce sandstorms, with significant improvements in local biodiversity and soil stability [4][14]. Group 2: Ecological Impact - The planted species, such as Haloxylon ammodendron (Salsola) and Caragana korshinskii (Flowering shrub), have deep root systems that stabilize the soil and enhance carbon sequestration [4][11]. - The project has resulted in a significant reduction in wind speed and sand erosion, with mature forests capable of reducing sand dust levels by over 68% [8][9]. - The total annual sand fixation capacity of the forests is approximately 67.41 million tons, equivalent to filling 270 Olympic-sized swimming pools [10][9]. Group 3: Economic and Social Benefits - The ecological tourism generated by the project brings in over 8 million yuan annually, with thousands of visitors participating in tree planting and educational activities [23][24]. - Local farmers have seen an increase in income, estimated at over 2 million yuan per year, through participation in tree planting and maintenance activities [24][25]. - The project has also created a platform for community engagement, with local farmers, businesses, and volunteers contributing to the ecological restoration efforts [27][28].
