Mauritius, a picturesque island nation in the Indian Ocean, is renowned for its vibrant biodiversity, turquoise lagoon and thriving tourism industry. However, beneath its natural beauty lies an urgent reality: climate change poses a significant threat to the environment, economy, and people of Mauritius. The island is grappling with rising sea levels, extreme weather events and the degradation of vital ecosystems. Addressing these challenges requires a united effort from individuals, communities and the global community. Dr Anusha Nawoor, Tunley’s Environmental Scientist and Mauritian native, gives a detailed insight on the impact of climate change in Mauritius and how it affects the economy.
The Evidence and Impact of Climate Change in Mauritius
The island's unique ecosystem faces threats such as coastal erosion, severe weather events and coral reef degradation. Understanding these threats is crucial to developing strategies for a resilient and sustainable future:
- Rising Sea Levels and Coastal Erosion
Mauritius is particularly vulnerable to rising sea levels, which are causing intensified coastal erosion. Beaches, wetlands and mangroves are under threat, endangering marine habitats and undermining the island’s tourism sector which is a cornerstone of its economy.
- Unpredictable Weather Patterns
While the weather in Mauritius is famed for its warmth and sunny beaches, it is also increasingly marked by unpredictable patterns and extreme events due to climate change. Tropical cyclones are becoming more frequent and severe, causing widespread destruction to buildings and agriculture. In addition, erratic rainfall patterns bring prolonged droughts that strain water resources, while intense downpours lead to flash floods, soil erosion and infrastructure damage.
- Coral Reef Degradation
Mauritius is surrounded by approximately 300km of coral reefs which play a significant role in marine ecosystems and coastal protection. Sadly, these reefs are bleaching due to rising sea temperatures and ocean acidification. Coral bleaching happens when corals experience stress from environmental changes, such as rising sea temperatures, increased ocean acidification or exposure to pollutants. This degradation directly impacts the Mauritian economy as it threatens fisheries and the livelihoods of communities that rely on marine resources.

- Threats to Biodiversity
Mauritius is home to unique flora and fauna, much of it endemic. However, climate change disrupts ecosystems and habitats, pushing many species toward extinction and upsetting the island’s ecological balance.
Implications for Key Sectors
- Agriculture
Mauritius’ agricultural sector, particularly sugarcane and vegetable farming, is highly sensitive to climate variability. Droughts reduce crop yields, while floods destroy fields, jeopardising food security and farmers’ livelihoods.
- Tourism
Tourism in Mauritius, which accounts for a significant portion of its GDP, is at risk. Climate-induced erosion, coral bleaching and extreme weather events reduce the island’s appeal as a destination for global travellers.
- Water Resources
Erratic rainfall patterns challenge water management. Droughts reduce reservoir levels, while excessive rainfall overwhelms drainage systems, straining freshwater supplies and increasing the risk of flooding.
National Efforts to Combat Climate Change
Mauritius is taking bold steps to address these challenges through mitigation and adaptation strategies:
- Renewable Energy Transition: The government aims to generate 60% of its electricity from renewable sources by 2030, scaling up solar, wind and biomass projects.
- Coastal Protection Projects: Initiatives to restore mangroves and coral reefs enhance natural defences against sea-level rise and extreme weather.
- Sustainable Agriculture: Farmers are being trained in climate-resilient practices, including crop diversification and efficient irrigation methods.
- Disaster Preparedness: Investments in early warning systems and resilient infrastructure help reduce the impact of extreme weather events.
- Environmental Awareness Campaigns: NGOs and government programs are educating communities about sustainable practices and conservation.
Opportunities for Innovation and Climate Resilience
While climate change presents serious challenges, it also opens avenues for progress and adaptation:
- Eco-Tourism: Mauritius can diversify its tourism sector by promoting eco-friendly travel experiences, including exploring inland rainforests and endemic wildlife.
- Green Economy: Transitioning to renewable energy and sustainable practices positions Mauritius as a leader in the green economy, attracting investments and creating jobs.
- Community Empowerment: Local conservation initiatives, such as tree planting and waste management, foster grassroots resilience and environmental stewardship.
What Can You Do as an Individual
Every individual living and visiting the Island can do their part in helping to combat climate change in Mauritius. Here are some simple steps one can take:
- Reduce Your Carbon Footprint: Use energy-efficient appliances, switch to renewable energy and minimise waste.
- Support Conservation Efforts: Volunteer with local organisations working to restore coral reefs or plant mangroves.
- Adopt Sustainable Practices: Support eco-friendly tourism and encourage businesses to adopt green initiatives.
- Advocate for Policy Changes: Engage in discussions and movements that push for stronger climate policies.
The Bottom Line
Urgent and collaborative action is needed to protect the environment, economy and people from the devastating effects of climate change in Mauritius. By embracing innovation, investing in climate resilience and fostering community involvement, the Island can chart a path toward a sustainable and thriving future. The road ahead is challenging, but with concerted efforts, Mauritius can preserve its paradise and ensure it remains a beacon of natural beauty and biodiversity for generations to come.
