Abstract

The extent to which the food supply aligns with the food and nutrition demand is unclear, which is crucial during crises like the COVID pandemic. Here, we present a geospatial framework integrating 3.8 million road segments for evaluating the food system resilience in alignment with Chinese dietary requirements. Results reveal that China faces challenges in achieving complete local self-sufficiency in specific foods and heavily relies on large-scale transport in a north-south direction. When comparing actual consumption to the ideal dietary requirements, there is average increased pressure of 6.1% in food transport intensity (i.e., from 0.6% in staples to 11% in oilseeds). Nevertheless, China's diverse food supply chain is rich, and the food system in the southeastern coastal cities (46% of all) is highly resilient, but resilience decreases from east to west. In the future, policymakers should prioritize local food distribution by building a centrally coordinated-locally autonomous supply and marketing network.

期刊介绍： Global Food Security plays a vital role in addressing food security challenges from local to global levels. To secure food systems, it emphasizes multifaceted actions considering technological, biophysical, institutional, economic, social, and political factors. The goal is to foster food systems that meet nutritional needs, preserve the environment, support livelihoods, tackle climate change, and diminish inequalities. This journal serves as a platform for researchers, policymakers, and practitioners to access and engage with recent, diverse research and perspectives on achieving sustainable food security globally. It aspires to be an internationally recognized resource presenting cutting-edge insights in an accessible manner to a broad audience.
