•Significant variations exist in SOC stocks among the studied land-uses.•The natural ecosystems of the Ethiopian highlands had the highest SOC stock.•Conversions to cropland and intensively grazed land are sources of CO2.•Estimated gains and losses of SOC stock revealed negative partial balance.•Enc...
