PORT LOUIS, MAURITIUS — Rising sea temperatures, pollution, and human activity are severely degrading Mauritius’ coral reefs, threatening the natural barriers that protect its coastline and famous beaches.
Warming seawater has caused mass coral bleaching, affecting the reefs that absorb 97 per cent of wave energy. According to Dachil Luchmun, Director of EcoSavants Consulting, the significance of reefs is that:
“Coral reefs are directly connected with beach integrity, and they are the first primary defence to our coast… They are submerged breakwaters, which protect our beaches.”
Despite contributing just 0.01 per cent of global greenhouse gas emissions, the Indian Ocean island nation faces disproportionately high climate risks. Overfishing, unsustainable tourism, and rising sea levels are accelerating coastal erosion, exposing tree roots and encroaching on shoreline properties.
The Mauritian government has decided to invest in regenerating its coasts, including planting seagrass and mangroves and restoring corals using heat-resistant varieties. Local specialists emphasise that this requires help from the international community.
“The global community can really help us because, as a small country, our budget is very tight, and these restoration and preservation projects are very costly,” Luchmun noted. “It’s not just for Mauritians, and we should be united as one to be able to continue to preserve these beautiful ecosystems.”
Rehabilitating these marine natural defences remains critical to safeguarding Mauritius’ environment, coastal communities, and vital tourism sector.
