摘要： The emission reduction potential of organic agriculture has received much attention in addressing the global greenhouse gas emission reduction challenge. However, studies assessing the carbon reduction potential of multicrop organic production at regional scales remain limited. This study assessed the status and regional differences in emissions from organic and conventional management of nine crops in Yunnan Province, China, through a two-year field study combined with life cycle assessment methodology. Additionally, this study innovatively introduces a scenario simulation based on the level of organic agriculture development in different regions of the world to explore the degree of realization of the maximum emission reduction potential (DMP) of organic agriculture in Yunnan Province under different development path scenarios. Results showed that organic management reduced carbon emissions by 6.28 %-56.25 % compared to conventional management practices. Spatially, carbon emission intensity was found to be higher in the southwest than in the south of Yunnan. In the Base-Current scenario, the DMP was only 2.88 %, while higher levels of DMP were observed under the S2 (European level), S3 (North American level), and S6 (Optimal level) scenarios, at 13.75 %, 10.77 %, and 32.76 %, respectively. Vegetables, fruits, and rice were the dominant sources of both emission reductions and total emissions, together accounting for 88.53 %-94.54 % of reductions and 68.15 %-73.33 % of emissions across the three scenarios. Achieving the maximum emission reduction potential (Base-Ultimate) could lower emissions to 30.21 Mt CO2 eq, a reduction of 36.53 % compared to current levels. These findings provide a basis for sustainable agricultural policy in Yunnan and insights for global climate mitigation strategies.
