(b) Enhancing the carbon sink capacity of ecosystems We will carry out large-scale programs to protect and restore major ecosystems. We will push ahead with large-scale afforestation, and consolidate achievements already made in returning marginal farmland to forests and grasslands, to increase forest and grassland resources. We will strengthen forest protection, and take targeted measures to improve the quality of our forests, so as to enhance the quality and stability of forests. We will step up efforts to protect and restore grassland ecosystems, and increase the overall vegetation coverage of grasslands. We will strengthen the protection and restoration of rivers, lakes, and wetlands. We will comprehensively protect and restore marine ecosystems, improve the carbon sequestration capacity of mangroves, seagrass beds, and salt marshes. We will move forward with efforts to restore and improve degraded land, and make comprehensive efforts to curb desertification, rocky desertification, and soil erosion. We will work to improve and restore environments surrounding abandoned mining areas. We will expand forest coverage around 25% of Chinas total land area and increase forest stock volume to 19 billion cubic meters by 2030.
