Coral reefs are vital ecosystems supporting diverse marine life and offering many benefits to coastal communities. However, climate change and pollution increasingly threaten them. According to the Global Coral Reef Monitoring Network (GCRMN), coral reefs cover only 0.2% of the ocean floor but provide 25% of the marine ecosystem’s benefits. Coral reefs also contribute £2.2 trillion ($2.7 trillion) to tourism globally. Mauritius, an island in the Indian Ocean, is home to stunning reefs. Despite their importance, coral reefs are increasingly damaged. Some scientists claim over 50% of reefs have been affected in the last 30 years. Dr. Anusha Nawoor, a Mauritian environmental scientist, explains coral bleaching and its impacts on Mauritius. The Mauritius Coral Crisis threatens the vibrant marine ecosystems surrounding Mauritius, endangering both biodiversity and local economies.
why is coral bleeching?
Coral bleaching happens when stress, such as rising sea temperatures or pollution, causes corals to expel algae. Without these algae, corals lose their color and become white. If the stress continues, corals may die, harming marine biodiversity and coastal protection.
how does climate change impact coral bleeching?
Climate change exacerbates coral bleaching. It increases ocean temperatures and acidification, putting reefs under more stress. The World Wildlife Fund urges nations to act urgently, reduce greenhouse gases, and protect reefs.
Mauritius has already felt the effects of climate change. Its average annual temperature has risen by 1.39°C over 70 years. The country faces increased drought, water shortages, and rising sea levels, impacting tourism and the economy.
current coral bleaching in mauritius
Mauritius has experienced coral bleaching, especially from December to March. Some reefs are recovering, while others remain damaged. Urgent action is needed to address the Mauritius Coral Crisis, with conservation efforts playing a key role in preserving the reefs. The government and NGOs monitor the situation and implement conservation efforts.
conservation efforts
Mauritius has initiated programs to protect its reefs. Marine protected areas, coral restoration projects, and public awareness campaigns aim to safeguard these ecosystems. Research and monitoring will help adapt strategies for long-term reef health.
