Scientists are increasingly recognizing the crucial role of healthy ecosystems in strengthening the resilience of atoll islands against rising sea levels. These islands, vital habitats for diverse species and human cultures, depend on thriving natural processes to withstand the impacts of climate change.
Atoll islands are formed from sediment produced by marine life, including corals and algae. Research indicates that healthy ecosystems on the islands and in surrounding waters are crucial for their survival. Restoring coral reefs and native forests are key nature-based solutions. Efforts include reclaiming seabird habitat, as seabird guano enriches reefs and boosts sediment production.
Conservationists are actively involved in recovery projects to enhance resilience in 2025. In the Maldives, partnerships focus on creating safe havens for birds and re-establishing the ecological connection between land and ocean. Similar projects are underway in the Marshall Islands, focusing on invasive rat eradication to allow seabird populations to recover and revitalize nutrient flows to the islands. These holistic approaches aim to secure the future of these vulnerable islands by fostering more resilient ecosystems capable of withstanding the challenges of rising sea levels.
