Recent developments in Manzanillo, Mexico, have raised significant concerns regarding the conservation of vital marine ecosystems. As of November 23, construction began on a major port expansion project in the western state of Colima, which includes a gasoline storage terminal and a gas and steam power plant.
Independent expert Hugo Smith warns that the environmental impact is "tremendous," particularly as the area supports agriculture, livestock, and artisanal fisheries. He highlights the risks associated with dredging, which can lead to increased pollution and the creation of new pollutants.
The expansion will cover an area of 1,800 hectares and is expected to be completed by 2030, with a public-private investment of approximately $3.48 billion. This project aims to make the port the largest in Latin America and the 15th largest globally.
However, the region is home to the Cuyutlán lagoon, a critical habitat for various species, including endangered birds and marine life. The lagoon is recognized as a priority marine and hydrological region, hosting 90% of Colima's wetlands.
Environmental authorities have expressed concerns that the port expansion could alter water levels and damage habitats crucial for nesting and feeding. Despite calls for an environmental impact assessment in 2017, the project has proceeded without comprehensive evaluation.
The local ecosystem, which supports around 20,000 migratory birds and various fish species, faces threats from climate change as well, with predictions of flooding due to rising sea levels by 2050.
In light of these developments, experts stress the need for better planning and monitoring to ensure the sustainability of both the port and its surrounding ecosystems.
