Abstract: Trade‐off conflicts among the Sustainable Development Goals have been a challenge. To reconcile frictional relationships among food production security (Goal 2), water use efficiency (Goal 6), and climate change mitigation (Goal 13), an empirical examination using deterministic frontier analysis was conducted globally. A single volume‐based index for each goal is too simple to evaluate the agricultural sustainability of different areas from the nexus assessment perspective. Our major findings are threefold. First, approximately two‐thirds of African countries have suffered from small food production and excess water use. Second, marked contrasts are observed in the possibilities of an increase in food production and reduction in water use and CO2 emissions among regions. Asian countries use water efficiently, whereas countries in the western regions control CO2 emissions. Third, trade‐offs among food production, water use, and CO2 emissions in agriculture are observed. It is almost impossible to reduce water use in Asia and CO2 emissions in the western regions for food production security. Based on the nexus approach, local strategies need to be compatible with global sustainability. Future research should identify the factors that determine the agricultural efficiency to devise local strategies, and develop policies simultaneously pursuing relevant environmental and well‐being goals.
