Fig. 4. Relative impact of agricultural soils to the overall agricultural sector, in terms of global warming potential (computed as absolute values for both sinks and sources combined for CO2, N2O, and CH4), as a percentage of the total agricultural sector emissions for some selected Annex 1 countries. "Other" emissions represent combined N2O and CH4 emissions from burning of savannas and crop residues and CH4 from rice.
