Shipping routes shift, endangering whales off South Africa

Conflicts in the Middle East have led to increased maritime traffic around South Africa, escalating the danger of ship strikes for whale populations. Since late 2023, rerouting away from the Red Sea has doubled the number of commercial vessels passing the Cape of Good Hope, amplifying collision risks.

This "extensive spatial overlap" between busy shipping corridors and whale habitats, including "superpods" of humpback whales feeding off the west coast, presents a severe threat. Researchers highlight that whales, often preoccupied with feeding, may not adapt quickly to the presence of fast-moving ships. Collisions are a primary cause of whale mortality, yet protection measures remain limited.

Solutions such as shifting traffic lanes slightly offshore could reduce strike exposure by 20-50 percent, with minimal impact on journey length. Some major shipping companies are already implementing protective measures. Further research into technologies like AI-enabled cameras and alert systems is underway to mitigate these risks.
