El Niño-driven climate variability can lead to simultaneous stress across major potato-producing regions in Asia, Europe, and the Americas. Drought and heat in some areas, coupled with excessive rainfall in others, disrupt irrigation systems and promote fungal diseases, reducing yields and quality. This imbalance creates global supply chain challenges, as potatoes are bulky and perishable, limiting redistribution. Industrial processors face higher costs due to inconsistent tuber quality, impacting production efficiency and market prices. In regions where potatoes are dietary staples, tighter supply may contribute to food inflation, while export-oriented areas could benefit from higher prices. Vulnerable rainfed systems and regions with limited infrastructure face the greatest risks.
