In light of nationalist trends, disruptions to global food supply chains and efforts to concurrently promote sustainable diets, we assess national capacities to achieve dietary guidelines based on domestic production alone. Over a third of all countries cannot meet self-sufficiency for more than two of the seven essential food groups. Low self-sufficiency and overdependence on a few countries for imports threaten their capability to respond to global shocks, particularly for small states.
鉴于民族主义趋势、全球粮食供应链的中断以及同时推动可持续饮食的努力，我们评估了仅基于国内生产来实现膳食指南的国家能力。超过三分之一的国家在七种基本食物类别中，无法实现超过两类食物的自给自足。低自给自足率以及对少数几个国家进口的过度依赖，威胁着它们应对全球冲击的能力，对小国而言尤为如此。
