The Growing Challenges Facing the Galápagos Islands Due to Increasing Tourism and Population
The Galápagos Islands, a UNESCO World Heritage site, are renowned for their unique and endemic species, such as giant tortoises and blue-footed boobies, coexisting with humans in a delicate balance. However, the islands are now facing significant challenges due to a rise in tourism and a growing population, which are straining the fragile ecosystem.
Biologist Carolina Proaño, who works in the humid highlands of the Galápagos, has been tirelessly working to save the critically endangered Galápagos petrel, a seabird that nests in the ground. On her family farm on Santa Cruz Island, Proaño has designated a protected area for the petrels and uses various methods to attract them, including playing recordings of their calls. Despite her efforts, she recently discovered two adult petrels dead near their nests, victims of stray dogs—a growing problem on the islands, introduced by humans.
Proaño’s experience highlights the broader issue of invasive species, which have become more prevalent as the human population increases. These species, including pets like dogs and cats that are often abandoned, pose a significant threat to native wildlife by preying on birds and their eggs. In addition to deliberate introductions, unintentional arrivals of insects and parasites via cargo ships have further complicated the islands’ biosecurity.
The parasitic fly Philornis downsi has had a particularly devastating impact on local bird populations, laying its eggs in nests and threatening already endangered species like the mangrove finch. Other invasive insects, such as fire ants and wasps, have also become problematic.
The influx of people and goods has not only introduced new species but has also led to environmental degradation. The lack of effective waste and water management systems has resulted in contaminated water being dumped into the sea and landfills overflowing with garbage. Overfishing has further stressed the marine ecosystem, with species like sea cucumbers and lobsters being overharvested due to their high market value.
Despite these challenges, there is potential for improvement. Experts like Alex Hearn from Quito’s Universidad San Francisco suggest better management of Galápagos fisheries could help fishers achieve higher prices for their products without resorting to harmful practices like longlining. This could involve using ecologically friendly methods and selling responsibly caught fish locally.
However, the response from local and national authorities has been mixed. The Charles Darwin Foundation and other key organizations have declined to comment on the growing pressures facing the islands, leaving many conservation efforts in limbo.
While some experts, like retired biology professor Gunter Reck, believe that the Galápagos ecosystems have remained resilient despite decades of pressure, they also acknowledge the need for continued conservation efforts. Reck argues that corrective measures have successfully rescued several species, but the situation requires ongoing attention.
The local community also faces economic challenges, particularly those dependent on tourism. After a record year in 2023, tourism has declined in 2024 due to concerns about rising violence in mainland Ecuador. This decline has had a ripple effect on the island’s economy, affecting everyone from independent guides to farmers.
To address these issues, Ecuador’s President Daniel Noboa recently announced an increase in entrance fees for the Galápagos, with international tourists now paying $200. However, local residents like naturalist Ramiro Adrian are skeptical about where this additional revenue will go, fearing it may not benefit the community as much as it should.
While the Galápagos Islands remain a symbol of conservation success, the growing pressures from tourism, population growth, and invasive species pose significant threats to their delicate ecosystems. Addressing these challenges will require a concerted effort from both local communities and international organizations to ensure the islands’ unique biodiversity is preserved for future generations.
