The Russia-Ukraine conflict reduced global wheat supplies, yet the food security implications vary across countries. We identify a 39% decrease in Ukrainian wheat exports in 2022 resulting in >70% import losses in some of the countries most vulnerable to these disruptions, with substantial impacts felt in Egypt, Oman, Saudi Arabia, Libya, Mauritania, Yemen and Lebanon. Differential impacts are a function of access to capital and international trade, suggesting the need for policy measures to defuse the impending food crisis.
俄乌冲突减少了全球小麦供应，但对各国的粮食安全影响不同。我们发现，2022 年乌克兰的小麦出口下降了 39%，这导致一些最容易受到这些干扰的国家的进口损失超过 70%，埃及、阿曼、沙特阿拉伯、利比亚、毛里塔尼亚、也门和黎巴嫩都受到了重大影响。不同的影响是获得资本和国际贸易的结果，这表明需要采取政策措施来化解即将到来的粮食危机。
