Abstract:The mitigation of greenhouse gas (GHG) emissions is of great significance for controlling global warming. In 2014, the CH₄ and N₂O emissions from farmland accounted for 4.3% of the total GHG emissions in China. After the carbon peak target in 2030, fossil energy in China will be gradually replaced by clean energy, and then the contribution of CH₄ and N₂O emissions from farmland will be enlarged, leaving that the urgency and importance of emission reduction becomes increasingly prominent. However, available technologies of emission mitigation have not been fully adopted and promoted due to the lack of legislation, education, publicity, achievement incentive mechanism, etc. The current situation makes the mitigation achievements fail to be implemented, thus being adverse to the smooth realization of national agriculture carbon mitigation goals. This study first summarizes the research progress of CH₄ and N₂O emission reduction in Chinese farmland and then points out the current problems of CH₄ and N₂O reduction. Finally, technical and policy suggestions are raised in four aspects: Operation and maintenance of long-term monitoring platform, the breakthrough of new methods and technologies, improvement of public awareness of emission reduction, and promotion and demonstration of achievements.
