Chile holds the world’s highest record of fatal collisions between whales and vessels. This scenario has worsened with the sustained increase in maritime traffic and has sparked an urgent debate on environmental governance.
Moreover, the situation affects not only biodiversity but also port planning and public policy. Consequently, science and the state are compelled to engage in faster dialogue. Thus, trade routes are beginning to clash with key areas for marine life.
Critical regions and affected species
In the far south, the Strait of Magellan emerges as one of the main focal points. There, the constant passage of large ships coincides with feeding areas of humpback whales.
At the same time, in the north of the country, Mejillones concentrates another sensitive area. The presence of thermoelectric plants, a mega port, and active routes intersect the habitat of the fin whale.
Meanwhile, the Coquimbo Region adds complexity. The routes to Valparaíso and San Antonio cross areas of high cetacean presence.
Megaprojects and cumulative risks
The possible increase in traffic associated with mining-port developments raises new alerts. These initiatives could intensify the pressure on multi-use conservation areas.
Furthermore, these spaces host colonies of Humboldt penguins and other fragile components of the ecosystem. Added to this is the risk of hydrocarbon spills.
Therefore, any incident would have effects that would spread to Punta Choros and Chañaral de Aceituno.
Science to understand the ocean
Scientific monitoring has become key to understanding the problem. Through photo identification, genetics, hydrophones, and satellite tagging, migratory routes in the Pacific are reconstructed.
In the Humboldt Archipelago, acoustic records reveal the almost permanent presence of the fin whale. This challenges the idea of seasonal visits and redefines the risk maps.
Likewise, sensors with cameras and accelerometers allow the observation of feeding behaviors and movement in three dimensions.
Measures Chile is adopting to reduce collisions
In response to this scenario, Chile has begun to test mitigation measures. One of the main ones is reducing speed in critical navigation zones.
In Mejillones, some shipping companies are applying a voluntary scheme that reduces speed from 15 to 10 knots when entering the port. Although incipient, the experience sets a precedent.
Additionally, the country is advancing in agreements with the maritime industry to use scientific data in the planning of safer routes.
Whales as indicators of environmental health
Whales function as sentinel species of the ocean. Their presence indicates areas where the ecosystem still maintains balance and productivity.
From an integrative perspective, protecting these animals also means safeguarding environmental and human health. Therefore, their study provides evidence for more sustainable public policies.
Ultimately, reducing collisions not only saves whales. It also allows for the organization of sea use in a country deeply connected to its coasts.
