This map shows soil organic carbon stocks that could be potentially vulnerable to human impact by 2050. We used the Predicted Soil Organic Carbon Stock dataset developed by Hengl and Wheeler (2018) as baseline and followed the Tier 1 approach on IPCC Guidelines for National Greenhouse Gas Inventories (IPCC 2006, 2014 and 2019) to estimate the portion of soil organic carbon (SOC) that could be potentially vulnerable to land use change during a 30 year period both in mineral and organic soils. Organic soils were defined as those with a probability equal or higher than 5% of being classified as Histosols in the Predicted USDA Soils Orders dataset by Hengl and Nauman (2019). The remaining land surface was considered mineral soil. We used the Copernicus land cover dataset (Buchhorn et al. 2019) to associate a land cover type to each pixel in the SOC baseline. This was later cross-walked to IPCC Land Use categories (IPCC 2006) and overlapped with IPCC Climate Zones (IPCC 2006) to estimate vulnerable SOC. Pixels classified as 'forest' were further stratified by management type according Lesiv et al. (2019). Vulnerable SOC was estimated and mapped based on the stock change factors (for mineral soils) and emission factors (for organic soils) available on IPCC Guidelines.
