CCA: Adaptation Strategies by Sector

A comprehensive and multi-sectoral approach to adaptation is essential for Mauritius to cope with climate change impacts. By investing in resilient agriculture, water management, coastal protection, infrastructure, health systems, and biodiversity conservation, Mauritius can enhance its adaptive capacity and ensure a sustainable and secure future.

Mauritius faces climate-related challenges across multiple sectors, including agriculture, water resources, coastal and marine ecosystems, infrastructure, health, and biodiversity. To ensure resilience, sector-specific adaptation strategies must be implemented.  

Agriculture and Food Security

Mauritius' agriculture sector is highly vulnerable to climate change, particularly due to droughts, erratic rainfall, extreme weather events, and rising temperatures. These changes threaten food production, reduce crop yields, and increase food insecurity. Adaptation strategies focus on improving crop resilience, irrigation efficiency, and sustainable land management.

Adaptation Strategies:

• Drought-resistant crop varieties:

  • Introduce and promote heat- and drought-tolerant crop species such as climate-resilient sugarcane, rice, and maize.
  • Encourage the use of salt-tolerant crops in coastal areas affected by salinization.
  • Support research and development in local universities and agricultural institutions to develop locally adapted crops.

• Smart irrigation systems (e.g., drip irrigation):

  • Promote drip irrigation and rainwater harvesting to optimize water use.
  • Provide financial incentives for farmers to adopt efficient irrigation technologies.
  • Encourage soil moisture conservation techniques such as mulching and cover cropping.

• Crop diversification:

  • Reduce dependency on a few major crops by introducing diversified cropping systems.
  • Encourage intercropping and agroforestry to enhance soil fertility and resilience to climate variability.
  • Support climate-smart livestock management to improve food security.

• Sustainable land and water management:

  • Promote conservation agriculture to maintain soil health and reduce erosion.
  • Implement integrated pest management (IPM) to reduce the use of chemical pesticides.
  • Strengthen farmer education programs on climate-resilient farming techniques.

Water Resources

Mauritius is increasingly facing water scarcity due to prolonged droughts, reduced rainfall, and salinization. Efficient water management is essential for agriculture, drinking water supply, and industry.

Adaptation Strategies:

• Rainwater harvesting and water storage systems:

  • Promote rainwater harvesting tanks for domestic and agricultural use.
  • Upgrade and expand water storage reservoirs to enhance resilience during droughts.

• Desalination and wastewater recycling:

  • Invest in desalination plants to ensure alternative freshwater sources.
  • Develop wastewater treatment and recycling programs to provide non-potable water for agriculture and industry.

• Integrated Water Resource Management (IWRM):

  • Implement watershed management programs to protect freshwater sources.
  • Promote water conservation policies for industries, households, and the agricultural sector.

• Early warning systems for floods and droughts:

  • Strengthen real-time monitoring of rainfall and groundwater levels.
  • Develop automated early warning systems to inform communities about water shortages and floods.

Coastal and Marine Adaptation

Mauritius' coastal and marine ecosystems are under threat from sea-level rise, coastal erosion, ocean acidification, and extreme weather events. These challenges pose risks to fisheries, tourism, and local communities.

Adaptation Strategies:

• Mangrove restoration and conservation:

  • Expand mangrove reforestation projects to protect coastlines from erosion and storm surges.
  • Establish community-based conservation programs to involve local populations in mangrove restoration.

• Coral reef restoration and marine protected areas:

  • Implement coral reef restoration projects using artificial reef structures and coral transplantation.
  • Expand marine protected areas (MPAs) to enhance fish populations and protect biodiversity.

• Coastal zone management policies:

  • Enforce strict coastal development regulations to prevent erosion and flooding.
  • Develop setback policies to control construction near vulnerable shorelines.

• Sustainable fisheries practices:

  • Implement fishing quotas and seasonal bans to prevent overfishing.
  • Promote alternative livelihoods for fishers, such as aquaculture and ecotourism.

Infrastructure and Urban Adaptation

With increasingly frequent extreme weather events, Mauritius needs climate-resilient urban planning and infrastructure to reduce flooding, storm damage, and heat stress.

Adaptation Strategies:

• Climate-resilient building codes and urban planning:

  • Enforce climate-smart building codes to withstand cyclones, floods, and rising temperatures.
  • Promote the use of green roofs and energy-efficient designs for urban resilience.

• Flood protection infrastructure (e.g., seawalls, drainage systems):

  • Improve stormwater drainage systems in flood-prone areas.
  • Construct seawalls, breakwaters, and natural barriers to protect coastal communities.

• Early warning systems for extreme weather events:

  • Strengthen weather forecasting technologies for better preparedness.
  • Develop mobile-based alerts to warn citizens of impending storms and cyclones.

Health Adaptation

Climate change has direct and indirect effects on public health, including heat stress, waterborne diseases, and vector-borne diseases such as dengue and malaria.

Adaptation Strategies:

• Surveillance and control of vector-borne diseases:

  • Enhance mosquito control programs to reduce the spread of malaria and dengue.
  • Improve disease surveillance systems to track outbreaks in real-time.

• Heatwave action plans:

  • Establish cooling shelters in urban areas to protect vulnerable populations.
  • Implement public awareness campaigns on heat safety measures.

• Improved healthcare infrastructure:

  • Strengthen climate-resilient hospitals and clinics to handle climate-related health emergencies.
  • Train health professionals on climate-related health impacts.

Biodiversity and Ecosystems

Mauritius is home to unique biodiversity, but climate change threatens forests, wetlands, and wildlife. Conservation efforts must focus on ecosystem-based adaptation (EbA) to protect biodiversity and maintain ecological balance.

Adaptation Strategies:

• Reforestation and afforestation programs:

  • Expand native tree replanting programs to restore degraded forests.
  • Promote community-led tree planting initiatives to combat deforestation.

• Ecosystem-based adaptation (EbA) approaches:

  • Protect wetlands, mangroves, and coral reefs as natural buffers against climate impacts.
  • Develop nature-based solutions, such as green corridors, to enhance biodiversity.

• Sustainable tourism practices:

  • Encourage eco-tourism initiatives that promote conservation and sustainable use of resources.
  • Implement strict environmental guidelines for tourism activities to minimize damage to ecosystems.
