Excessive fertilisation, improper nutrient management, and specific climatic factors are the main reasons for high environmental risks associated with agricultural production in subtropical plateau regions. However, quantitative data of impacts emission reduction potential remain unclear. The development such systems is likely to be significant. In that context, we conducted a case study Yunnan Province, China, quantify impact crop from 2002 2021. A life cycle assessment method was employed identify driving impacts, mitigation strategies were proposed. yield total input grain crops Province increased over 20-year period, footprint higher than other average annual mean greenhouse gas (GHG) emissions, soil acidification (AP), water eutrophication (EP) 2021 837 kg CO2-eq·Mg−1, 15.7 SO2-eq·Mg−1, 2.71 PO4-eq Mg−1, respectively. Environmental emissions mainly originate application inputs (including fertilisers (N, P, K), pesticides, seed, diesel fuels, plastic film) during cycle. There significant correlation between surplus nitrogen impacts. Scenario testing showed optimised management practices could increase reduce costs. GHG AP, EP rice, wheat, maize expected decrease by 43.0–59.5%, 51.5–64.5%, 57.4–71.5%, respectively (scenario 4, S4). Based on these findings, propose com-prehensive measures can negative environment areas help achieve sustainable development.
