GHG Emissions (IMAGE) Kazan Federal University Caption Figure 2. GHG emissions of food production and trade within the territory of the former Soviet Union (FSU). (A): Net cumulative change in GHG emissions of all years from 1992 to 2011 minus the average emissions of 1986 to 1991. Increasing crop exports resulted in a negative net cumulative change in emissions due to the consumption-based approach followed in this study. (B): annual rate of soil organic carbon sequestration on cropland that was abandoned after 1991 in the FSU. (C): GHG emissions embodied in domestic livestock production and in imports of livestock products to the FSU. (D): GHG emissions embodied in domestic crop production, crop exports, and imports of crops to the FSU. Note the different y-axis scales. Dashed vertical lines mark the end of the Soviet Union. Light-colored shades represent the 95% confidence intervals.
