A Study on Dynamic Change of Liaoning Agricultural Carbon Footprint

Abstract:

Agricultural producing activity is one of the emission sources of greenhouse gases, and carbon footprint is a new concept emerging in the context of developing low-carbon economy. In this paper, the agricultural carbon footprint in Liaoning Province was calculated and analyzed with carbon footprint method. According to the results, carbon cost caused by the application of chemical fertilizer and land irrigation, as well as the application of diesel oil in agricultural machinery takes up a high percentage in the input carbon footprint, and the total carbon footprint increases year by year. The carbon intensity calculated in unit output occurs in a declining trend, while the carbon intensity calculated in unit cultivated area fluctuates constantly in a small range, and the carbon efficiency occurs in evident increasing trend. Finally, deficiencies of the study and problems that should be further discussed were proposed.
