Climate change control requires more land to increase ecosystem carbon sequestration. With the high-intensity development of mineral resources in past decades, massive mining areas have been generated worldwide. However, few studies evaluated sequestration these areas. In this study, we analyzed net productivity (NEP) changes and calculated NEP losses global terrestrial We adopted random forest model evaluate recovery potential its driving factors. The key findings are that (1) exhibited a relatively obvious decreasing trend from 2000 2020, with an overall reduction 29.1% maximum decline 35.7%. By loss was 11.9 g C m−2 year−1, total reached 576.9 Gg year−1. (2) Global demonstrate significant potential, average 12.0 Notably, Oceania South America significantly higher potentials, mine site potentials 15.9 year−1 16.1 contrast, European mines considerably lower less than 10 Asia, North Africa, varies widely mine, but generally meets average.
