多重风险因素正在汇聚，可能在未来数年内引发全球粮食危机。美国国家海洋与大气管理局预测厄尔尼诺现象在2026年有63%的概率达到"非常强"强度1，太平洋海温预计上升3.6摄氏度，几乎是2015-2016年厄尔尼诺事件的两倍1。世界银行警告，这一现象可能导致受影响地区水稻产量下降20%-50%1。考虑到印度生产全球近三分之一的水稻且大部分供国内消费1，而该国6月降雨量已比正常水平少约40%1，粮食供应风险尤为突出。
地缘政治冲突进一步加剧了粮食安全隐患。全球约三分之一的肥料通过霍尔木兹海峡运输1，该地区的中东冲突可能打断这一关键运输通道。专家预测中东冲突可能导致到2030年数百万人陷入饥饿1。乌克兰战争的持续影响也不容忽视。国际机构已发出警告，若这些风险因素同时发生，粮食通胀可能在2027年超过5%1，JP摩根的分析表明，厄尔尼诺结合100美元的油价可能导致粮食通胀上升1.5%1。
当前全球粮食形势面临不确定性。虽然去年全球谷物产量创历史新高1，粮食价格自2022年的高峰以来也下降了近20%1，但这些积极因素可能难以抵消即将到来的多重冲击。联合国表示，全球约2.66亿人面临急性饥饿，其中超过一半是由于冲突造成1。
A convergence of climate disruption and regional conflicts could trigger a severe global food crisis by 2027, according to multiple warnings from international institutions. The U.S. National Oceanic and Atmospheric Administration predicts a 63% probability that El Niño will reach "very strong" intensity in 2026, with Pacific ocean temperatures potentially rising 3.6 degrees Celsius—nearly double the levels recorded during the 2015-2016 El Niño 1. The World Bank has cautioned that such conditions could reduce rice production in affected regions by 20% to 50% 1, a particularly acute concern given that India produces roughly one-third of the world's rice supply, with most serving domestic consumption 1.
The impact of El Niño would compound existing vulnerabilities exacerbated by ongoing conflicts. Approximately 266 million people currently face acute hunger globally, with more than half of this suffering attributable to conflict 1. Tensions in the Middle East could plunge millions into hunger by 2030 1, while roughly one-third of global fertilizer supplies transit through the Strait of Hormuz, a chokepoint vulnerable to regional disruption 1. JP Morgan forecasts that the combination of El Niño with oil prices reaching $100 per barrel could raise food inflation by 1.5% 1, with broader projections suggesting food price inflation could exceed 5% by 2027 if multiple risks materialize simultaneously 1. Although global cereal production reached a historic high last year and food prices have declined roughly 20% since their 2022 peak 1, these gains remain fragile against mounting environmental and geopolitical pressures.
