China’s accelerated food imports have far-reaching implications for global resource allocation and environmental development. Hence, detailed information regarding China’s food trade resource-environmental impacts is imperative for the design of effective policies that promote environmental mitigation and resource conservation. This study estimated the spatial transfers of virtual water trade (VWT), virtual land trade (VLT), and virtual GHG emission trade (VGT) embodied in China’s food trade. Findings indicate that the VWT, VLT, and VGT transfers embodied in China’s food trade increased by 10.4 %, 9.8 %, and 15.2 % annually. It is more important to mention that virtual water import (VWI) and virtual land import (VLI) saved 119.5 × 10<sup>9</sup>m<sup>3</sup> of global water resources and 29.5 Mha of land resources, respectively, but virtual GHG emission import (VGI) increased global 13 Mt CO<sub>2</sub>-eq GHG emissions. The divergent impacts of China’s food import on global food sustainability stem from variations in virtual water content, yields and emission intensities. Moreover, significant differences in sustainability scores were found among the top 15 importing countries, indicating that China’s food trade contributes to the deepening of global food system sustainability. This study highlights the need for a multifaceted approach that considers the various environmental impacts of food trade. China is therefore encouraged to fully integrate the benefits of resource and environmental conservation into its sustainable food trade strategy, restructuring the food system to ensure the long-term nourishment of its large population.</div></div>","PeriodicalId":52374,"journal":{"name":"Geography and Sustainability","volume":"6 6","pages":"Article 100339"},"PeriodicalIF":8.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144887575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ER projects were primarily implemented in northern and southern farmland regions characterized by low ecological resilience. Pathway analysis identified that favorable climates significantly enhanced the temporal stability of ES provision, and rugged topography improved the ecological resistance. However, fragmented landscape patches disrupted stable ES provision by reducing ecological connectivity, and socioeconomic development diminished both resistance and resilience through land-use intensification.

The conference featured several important international initiatives: the establishment of the African Chapter of the International Geographical Union Commission on Geography and Sustainability, the launch of Phase II of the Global Dryland Ecosystem Programme, and the signing of a cooperative agreement between the Geographical Society of China and the Egyptian Geographical Society. The wider discussions reflected a growing need to further develop integrated geography as a coherent discipline to better understand and respond to complex human natural interactions.

Population exposure to EHEs across the four UTCI thresholds (> 26 °C, > 32 °C, > 38 °C, and > 46 °C) shows an increasing trend.

The eastern and southeastern regions, especially the Yangtze River and Pearl River Delta, show significant GDP exposure increases under SSP3–7.0 and SSP5–8.5.

This study employs MIKE SHE/11 model coupled with statistical analysis for such resolution. Across four scenarios ranging from light to heavy rainfall, we identified regime shifts in UGI system through the decreasing to increasing trends of sink fractions, typically occurring around 13–18 h after rainfall starts. Based on these regime shifts, we categorized the UGI system into vulnerable, reliable, and recoverable components, highlighting its heterogeneous performance. In addition, by examining the influence of vegetation structure on sink–source dynamics, we found that a higher probability of sinks under light rainfalls was associated with a greater leaf area index (LAI) and vegetation height standard deviation (VH<sub>STD</sub>), while green volume (GV) and canopy height (CH) played a more prominent role under heavier rainfalls. Threshold effect analysis further revealed that, a high proportion of the recoverable parts met the thresholds of CH (82 %) and GV (85 %), whereas fewer reached the thresholds of LAI (15 %–19 %) and VH<sub>STD</sub> (3 %–6 %).
