🌊 Mauritius’s Coral Reefs Are Dying — Will the World Listen in Time?

• 11 June 2025

As global leaders meet in Paris to discuss the ocean’s future, Mauritius’s marine heritage is already under threat.

Mauritius, 11 June 2025 — While global environmental leaders gather in Paris for the UN Ocean Conference 2025, the lagoons of Mauritius are sounding their own silent alarm. Coral reefs, the very foundation of our marine ecosystem, are bleaching and dying — and urgent action is needed at both international and local levels.

This year’s Paris conference is focused on “Rebuilding Marine Life for People and Planet”, echoing the urgency felt on small island states like Mauritius. Rising sea temperatures, pollution, and climate change are destroying coral ecosystems — the underwater rainforests that protect biodiversity, coastlines, and communities.

🔍 What’s Happening Underwater?

Mauritius has already lost up to 50% of its live coral cover in some lagoons, according to the Mauritius Oceanography Institute (MOI). Coral bleaching, caused by stress from warm waters, causes corals to expel the algae they need to survive — turning ghostly white and eventually dying.

Mass coral bleaching events occurred in 2009, 2016, and again in 2023, showing a pattern that mirrors the global rise in ocean temperatures.

📉 Why This Should Worry Everyone

Coral reefs are not just beautiful; they are life-sustaining. Here's what we stand to lose:

Without urgent action, Mauritius faces threats to its food security, tourism industry, and coastal stability.

🌍 A Global Forum with Local Relevance

The UN Ocean Conference in Paris brings together nations, scientists, NGOs, and businesses to tackle the crisis facing oceans. For Mauritius, these global discussions are not abstract — they are about our survival.

Forums like this are essential to:

• Push for global funding and climate justice for island nations

• Share innovative marine solutions (e.g., coral farming, blue finance)

• Strengthen collaborations between international and local conservationists

• Highlight the unique vulnerability of Small Island Developing States (SIDS)

🌱 The Local Warriors on the Frontline

Despite limited resources, several Mauritian NGOs are taking action:

• Reef Conservation – Managing coral nurseries and marine education in the north

• EcoSud – Actively protecting the Blue Bay Marine Park through community engagement

• MMCS (Mauritius Marine Conservation Society) – Promoting marine research and public awareness

• EcoMode Society – Advocating for sustainable marine tourism and clean ocean practices

Their grassroots efforts align with SDG 14 – Life Below Water, which calls for the conservation and sustainable use of oceans and marine resources.

🧭 What You Can Do

You don’t need to be a scientist or policymaker to help:

• ✅ Use reef-safe sunscreen

• ✅ Don’t step on or collect corals

• ✅ Participate in clean-up drives and conservation programs

• ✅ Support and donate to local NGOs

• ✅ Cut down on plastic use

• ✅ Share this message and raise awareness

⚠️ The Clock Is Ticking

The decisions made at global conferences like the one in Paris must translate into real support for local communities and ecosystems. For Mauritius, the next 10 years are critical — if we don’t act now, we may lose the coral reefs that define our seas, our identity, and our economy.

The ocean is calling — and it’s up to all of us to answer.
