Peru Faces Crisis as Seabird Populations Plummet Due to Climate Change

Along Peru's central Pacific coast, scientists warn of a drastic decline in seabird populations, primarily guano birds, due to climate change, disease, and overfishing. Numbers have decreased from 4 million in 2022 to just half a million in 2023. This impacts Peru's natural fertilizer industry reliant on seabird populations.

On Peru's central Pacific coast, environmental scientists are raising alarms about the alarming decline in seabird populations, including guano birds, sea lions, and penguins. Factors contributing to this issue include climate change, disease, and overfishing, which threaten the survival of these crucial species. Since 2022, the population of guano birds has dropped from 4 million to around 500,000.

These guano birds are critical to Peru's ecosystem and economy due to their production of nutrient-rich excrement, used as natural fertilizer. 'We are very alarmed by this sharp decline,' stated Susana Cardenas from Peru's Cayetano Heredia University. Her research shows that dramatic population decreases pose a severe risk to local wildlife and agriculture.

The decline, exacerbated by avian flu, El Nino, and overfishing, is also impacting the guano fertilizer harvest, vital for local farming. Despite governmental plans for repopulation and increased anchoveta catch quotas, experts remain concerned about the long-term effects on seabird species, including the risk of extinction for species like Humboldt penguins.
