Total carbon per land unit for 2018 in t/ha
Total carbon per land unit includes the soil organic carbon as calculated from ISRIC soil data as well as the carbon computed from biomass for the herbaceous, woody and litter vegetation components. SANLC2018 was used to allocated the total carbon proportionally to different land cover classes.
Soil loss from ISRIC reference data (2018)
The total carbon per land unit in South Africa was determined with ISRIC Africa SoilGrids data and vegetation biomass. By using the South Africal National Land Cover 2018 product the estimated soil loss for the country could be calculated. The ISRIC data was released in 2015
Total Woody Biomass in gC.m2
Total woody biomass is the sum of the above ground and below ground woody biomass as proportionally divided per land cover for 2014. Values in this layer is in gC.m2
Total Herbaceous Biomass for 1990 in gC.m2
Total herbaceous biomass is the sum of the above ground and below ground biomass per land unit, proportionally allocated to land cover classes using the NLC1990

The historical survey data were transcribed from the Department of Agriculture `Report of the Marine Biologist` (pre-1900) and `Report of the Government Biologist` (1900-1904) publications for the period of 1897-1904. The data from 1920-1949 were transcribed from the Union of South Africa series of `Fisheries and Marine Biological Survey` reports, which in 1935 became the Department of Commerce and Industries` `Fisheries and Marine Biological Survey Division` reports, and from 1937 onwards were published as `The...

Above ground herbaceous biomass for 2018 in t/ha
The above ground herbaceous biomass is a very small fraction of the total terrestrial organic carbon stocks and it was calculated with the same model as in the 2014 NTCSA dataset. The equation incorporates Rain Use Efficiency, amount of rain required to enable production per year and tree cover fraction. A mean herbaceous layer is modelled based on mean long term rainfall. The above ground herbaceous biomass was based on harvest factors obtained from the...
Soil Organic Carbon in Topsoil (30cm depth) - 2018
ISRIC soil data is available in 6 depths of which the 0-5, 5-15 and 15-30cm layers were aggregated to obtain the soil organic carbon for topsoil. The values of this layer was adjusted by taking land cover / land use into account by using the SANLC2018
Total Soil Organic Carbon for 1990 in t/ha
ISRIC Africa SoiGrids data were used to calculate a reference layer of soil organic carbon (SOC). It was done by using the organic carbon content and bulk density data sets available at 250m resolution and for 6 different depths. The data was aggregated to a depth of 30cm for topsoil and 100cm for subsoil. The impact of land use on the SOC is included by incorportating the 1990 National Land Cover data set for South...
