Mauritius — Known for its crystal-clear waters and vibrant marine biodiversity, Mauritius is making waves with a series of impactful initiatives to protect its ocean ecosystem. As climate change, pollution, and over-fishing threaten the island’s marine environment, the government, private sector, and international organizations are stepping up their efforts to ensure a sustainable future.
UN-Backed Aquaculture and Anti-Plastic Measures
In partnership with the United Nations under the Oceans Partnership framework, Mauritius has launched a dual-front strategy aimed at protecting marine life while promoting sustainable development.
- Sustainable aquaculture projects are now underway to balance fish and hydroponic farming with marine conservation. These initiatives seek to reduce pressure on wild fish populations while providing alternative livelihoods for coastal communities.
- At the same time, plastic pollution is being tackled head-on. The government has reinforced bans on single-use plastics, while grassroots beach cleanups and enhanced recycling systems are gaining momentum. These actions form part of a broader environmental reform to safeguard marine habitats from waste contamination.
Seagrass Nursery Breakthrough at Four Seasons Resort
On April 8, 2025, the Four Seasons Resort at Anahita launched the Indian Ocean’s first sea-grass nursery in collaboration with the Odysseo Foundation. The project focuses on cultivating and transplanting sea-grass to restore vital underwater meadows that support marine biodiversity including turtles, rays, and juvenile fish and significantly boost carbon capture. This initiative not only enhances ecosystem resilience but also sets a precedent for private-sector involvement in ocean restoration.
Lingering Aftermath of the 2020 MV Wakashio Oil Spill
Nearly five years after the MV Wakashio disaster, new studies from Curtin University reveal that oil residues still contaminate mangrove forests, including those within protected Ramsar sites. The persistent pollution underscores the long-term ecological impact of maritime accidents, drawing parallels with cases like Kochi, India, where mangroves remain tainted years after oil spills. This ongoing contamination threatens local biodiversity and highlights the need for stronger disaster response frameworks and long-term environmental monitoring.
Coastal Erosion and Coral Decline Intensify
Mauritius is facing alarming rates of coastal erosion and coral reef degradation, according to the UNDP. Between 1997 and 2007, live coral cover plummeted by up to 70%, while beach erosion has advanced inland by as much as 20 meters in some areas. These changes are linked to sea-level rise, weakening reef barriers, and intensified storm surges. As these natural defenses deteriorate, both marine life and coastal communities face heightened risks.
Protecting Mauritius’ Ocean: A National Imperative
To address these mounting challenges, Mauritius is adopting a multi-pronged, science-based strategy centered around the following priorities:
- Expanding and Enforcing Marine Protected Areas (MPAs)
Increasing the coverage of MPAs can shield critical habitats such as coral reefs, mangroves, and fish spawning zones. Enhanced enforcement, adequate funding, and active community participation are vital for the success of these zones.
- Restoring Coastal Habitats
Efforts are underway to restore coral reefs, replant mangroves, and conserve sea-grass beds. Community-led initiatives are training locals in restoration techniques, creating both environmental and economic benefits.
- Combating Marine Pollution
Pollution from plastic waste, agriculture, and untreated wastewater continues to endanger marine life. Mauritius is taking steps to implement stricter waste regulations, improve recycling programs, and install modern wastewater treatment systems.
- Educating and Engaging the Public
Marine conservation education is being integrated into schools, and citizen science programs are empowering locals and tourists alike to monitor marine health. Traditional ecological knowledge is also being recognized as a valuable tool in sustainable resource management.
A Call for Unified Action
Mauritius’ ocean is more than a scenic backdrop—it is the lifeblood of the nation’s culture, economy, and future. As the island faces unprecedented environmental threats, the time to act is now. Collaborative efforts from government bodies, private institutions, communities, and international partners will be critical in preserving this ocean paradise for future generations.
The Blue Heart of Mauritius must be protected—not just for today, but for tomorrow!
