摘要：Increasing soil organic carbon (SOC) in natural and cultivated ecosystems is proposed as a natural climate solution to limit global warming. SOC dynamics is driven by numerous factors such as land-use change, land management and climate change. the amount of additional carbon potentially stored in the soil is the subject of much debate in the scientifc community. We present a global database compiling the results of 217 meta-analyses analyzing the efects of land management, land-use change and climate change on SOC . We report a total of 15,857 efect sizes, 6,550 directly related to soil carbon, and 9,307 related to other associated soil or plant variables . The database further synthesizes results of 13,632 unique primary studies across more than 150 countries that were used in the meta-analyses . Meta-analyses and their efect sizes and were classifed by type of intervention and land use, outcomes, country and region . This database helps to understand the drivers of SOC sequestration, the associated co-benefts and potential drawbacks, and is a useful tool to guide future global climate change policies .
