“…China announced at the 75th session of the UN General Assembly that it would take stronger policies and measures to reach peak carbon emissions by 2030 and also aims to achieve carbon neutrality by 2060. However, as the only major economy to achieve carbon emission growth by 2020 2 , China will face the problem of carbon reduction and development in achieving the above “dual carbon” target. Agriculture occupies a special position in climate change.…”

Carbon sequestration in farmland ecosystems is an important link in the world carbon cycle and plays an important role in regional carbon reduction. Guangdong, a major industrial and economic province in China, was used as the study area, and the period 2001–2020 was taken as the study period. The carbon emissions, sequestration, and footprint of farmland ecosystems in Guangdong were estimated using carbon emission factors for agricultural inputs that are closer to the actual situation in China. The study showed that: (1) Carbon average emissions from farmland in Guangdong during the study period was 3.7624 million t a−1, with a balanced overall trend of change, and that nitrogen fertilize applications was the main factor contributing to carbon emissions. (2) The carbon sink capacity of Guangdong farmland ecosystems showed an overall decreasing trend of 10.32%, with an average annual carbon sink of 19.0363 million t a−1. Paddy and sugar cane cultivations were the main factor of carbon sink in farmland. (3) The average annual carbon footprint of Guangdong's farmland ecosystems was 531,100 ha a−1, which was in a carbon surplus. Carbon surplus and footprint showed a decreasing trend year by year. The paper results provide a theoretical basis for the formulation of carbon emission reduction policies and industrial restructuring in Guangdong and provinces with the same industrial structure.

The abstract must not include a heading. It should be no more than 200 words long and contain no references or subheadings.The sequestration of carbon by agricultural ecosystems is an important part of the world carbon cycle and plays an important role in carbon reduction in all Chinese provinces, especially industrial provinces. Taking Guangdong Province, a major industrial province, as an example, and estimating the carbon emissions, carbon sequestration, and carbon footprint of Guangdong's farmland ecosystems and analyse the inter-annual dynamics of the three, to provide a theoretical basis for the formulation of carbon reduction policies and industrial restructuring in Guangdong and other provinces with similar industrial structures in the context of the “dual carbon” target. The study shows that, over the past 20 years, the annual average carbon emissions from farmland in Guangdong Province has been 3.7624 million , with the overall variation is basically the same, and the main factor of total carbon emissions is the amount of nitrogen fertilizer applied. The overall carbon sequestration capacity of Guangdong's farmland ecosystems showed a decreasing trend, with a decrease of 10.32%, and the average annual carbon sequestration amount was 19.0363 millionand the main influencing factor of the total carbon sequestration is the economic production of paddy and sugar cane. The average annual carbon footprint of Guangdong's farmland ecosystems is 531,100, which is in a state of carbon ecological surplus, at the same time the carbon surplus and carbon footprint show a decreasing trend year by year.
