El Niño phenomenon threatens fisheries and coastal regions in Ecuador and Peru

The El Niño phenomenon is intensifying across South America, causing significant ocean warming and sea level rises in Ecuador and Peru. In Ecuador, sea levels have risen by up to 40 centimeters, increasing the risk of coastal erosion, flooding, and damage to infrastructure and tourism. The warming has severely impacted the fishing industry; tuna catches are projected to drop by approximately 90,000 tons this year as species migrate to deeper, cooler waters. Artisanal fishermen also report increased costs due to longer voyages and the presence of crustaceans that damage nets.

The aquaculture sector is also on alert, with the National Aquaculture Chamber proposing strict environmental monitoring to protect shrimp production from temperature and oxygen fluctuations.

In Peru, meteorologists warn of an extraordinary El Niño event that could peak late in 2026, with thermal anomalies exceeding those of the devastating 1997-1998 period. Millions of people are at risk, with northern regions facing intense rainfall and floods, while southern areas face potential droughts. Authorities are preparing for worst-case scenarios, focusing on riverbed cleaning and emergency supplies to mitigate the impact of expected heavy rains and landslides.
