El Niño phenomenon impacts ecosystems and food security across the Americas

The El Niño phenomenon is exerting widespread pressure on ecosystems, agriculture, and economies across the Americas. In South America, the phenomenon is expected to peak in intensity by late 2026 or early 2027, bringing significant risks. In Argentina, authorities are monitoring potential flooding in the Litoral and Pampa Húmeda regions due to increased rainfall. In Colombia, the Instituto Colombiano Agropecuario has advised farmers to monitor crops for drought and pests, while coral reefs in San Andrés and Providencia face thermal stress and potential bleaching.

Economic and food security implications are mounting. In El Salvador, analysts warn that El Niño could drive up food prices through 2027, particularly affecting grain availability. In Ecuador, heavy rains have forced Agroazúcar Ecuador S.A. to end its sugar harvest early, necessitating sugar imports to meet domestic demand.

Marine environments are also under threat. Studies indicate that Pacific warming is altering ocean currents and reducing oxygen levels in deep waters, shrinking usable habitats for marine life. Additionally, in Veracruz, Mexico, a massive five-kilometer debris accumulation caused by heavy rains threatens to damage local coral reefs and navigation.
