Peru has declared a 60-day state of emergency across 1,380 districts in 191 provinces following forecasts of rainfall associated with the 2026–27 El Niño. The measure, announced on November 3, covers several potato-growing regions, including Puno, Cusco, Junín, Huánuco, and Ayacucho.

According to Peru's ENFEN commission, coastal El Niño conditions are expected to remain at extraordinary intensity through February 2027, with rainfall above normal forecast for northern and central coastal areas and parts of the Andes.

Excessive rainfall could disrupt potato planting, cause waterlogging, restrict field access, and increase late blight pressure. Meanwhile, below-normal rainfall is forecast around Lake Titicaca and could affect soil moisture and crop establishment.

However, no confirmed estimate of potato crop losses has been published. An October assessment classified only two of 950 districts as high-risk for potatoes.

Elsewhere, Kenya faces increased rainfall and associated disease risks, while India has experienced localized planting delays. Southern Africa faces forecasts of hotter and drier conditions.

Despite these risks, there is currently no verified evidence of a global El Niño-related potato shortage. Actual impacts will depend on rainfall, crop establishment, and disease development.
