The land use, land-use change, and forestry (LULUCF) is one of the greenhouse gas inventory sectors that cover emission and removals of greenhouse gases resulting from land use such as agricultural activities and land use change. Particularly, LULUCF-Cropland sector consists of carbon stock changes in soil, N₂O emissions from disturbance associated with land use conversion to cropland, and CO₂ emission from agricultural lime application. In this paper, we conducted the study to calculate the greenhouse gases emission of LULUCF- Cropland sector in South Korea from 1990 to 2014. The emission by carbon stock changes, conversion to cropland and lime application in 2014 was 4424, 32, and 125 Gg CO₂-eq, respectively. Total emission from the LULUCF- Cropland sector in 2014 was 4,582 Gg CO₂-eq, increased by 508% since 1990 and decreased by 0.7% compared to the previous year. Total emission from this sector showed that the largest sink was the soil carbon and its increase trend in total emission in recent years was largely due to loss of cropland area.
