African penguins could be extinct by 2035 how to save them

Farmer's Weekly

December 06, 2024

Protecting the critically endangered African penguin is good for the environment, other animal species, and the economy, say Lorien Pichegru and Dr Alistair McInnes of Nelson Mandela University, Katrin Ludynia of the University of Cape Town, and Peter Barham of the University of Bristol in the UK.

African penguins could be extinct by 2035 how to save them

In October 2024, the African penguin became the first penguin species in the world to be listed as critically endangered by the International Union for the Conservation of Nature.

This is a sad record for Africa’s only penguin and means it is now just one step away from extinction.

How did this happen? African penguins (Spheniscus demersus) are found only in Namibia and South Africa. Their numbers have been declining since the 1800s. At that time, they were burnt in ships’ boilers, their eggs were harvested and consumed as a delicacy, and their nests were destroyed by guanoharvesters seeking a rich source of fertiliser.

Such activities are fortunately no longer allowed. African penguins have been protected under South Africa’s Sea Birds and Seals Protection Act since 1973 (and more recently under the Marine Threatened or Protected Species Regulations since 2017).

These laws and regulations ban the capture of penguins or their eggs, and any intentional harm done to them. Fertilisers no longer use guano (penguin excrement). After egg and guano harvesting stopped, the lack of prey (small fish like sardines and anchovies) became the main issue for penguins from the early 2000s.

CANARIES IN THE COAL MINE

The impacts of climate change on the distribution and abundance of their food, and competition with industrial fisheries, contributed to a 70% reduction in this penguin’s population between 2000 and 2024.

We are a group of scientists from universities and non-governmental organisations that have, for years, focused on solutions to save the African penguin. Today, unless the South African government takes urgent steps to protect the African penguin, it is likely to become extinct in the wild by 2035. At present there are fewer than 20 000 birds left in the wild. Penguins are like the canaries in the coal mine.
