Le Morne Voluntary Marine Conservation Area (VMCA):

A Nature-Based Climate Adaptation Initiative in Mauritius

Project Overview

The Le Morne lagoon is one of Mauritius’ most ecologically significant coastal systems, hosting extensive seagrass meadows that support fisheries, biodiversity, coastal protection, and climate resilience. However, these ecosystems face increasing pressure from:

  • Boat anchoring and propeller scarring

  • Unregulated lagoon use

  • Coastal development

  • Climate change impacts

To address these challenges, the project—jointly implemented by CGC and EMCL—developed and operationalised a Voluntary Marine Conservation Area (VMCA) through a participatory, science-based approach

Objectives

The project aimed to:

  • Establish a community-led VMCA (~5.9 hectares) in Le Morne

  • Protect and restore seagrass ecosystems

  • Strengthen community stewardship and co-management

  • Reduce physical damage from anchoring and lagoon activities

  • Increase awareness on the ecological and economic value of seagrass

Key Results & Achievements

  • VMCA Successfully Established (~5.9 hectares protected area in Le Morne lagoon, clearly mapped and demarcated, community-recognised conservation zone, 92 direct beneficiaries involved in the project, inclusive participation: 36 women and 56 men) 👉 Significant improvement in community ownership

  • Reduction of Human Impact (Awareness reduced destructive lagoon practices, improved compliance with sustainable use, bathymetric maps produced, seagrass distribution and biotope mapping completed, monitoring of seagrass species health ongoing) 👉 Confirmed healthy and resilient seagrass ecosystems

  • Biodiversity Recovery Indicators (Juvenile fish, sea cucumbers, sea urchins, coral species recorded) 👉 Demonstrates ecosystem functionality and nursery role of seagrass

Sustainability & Replication

The VMCA model is:

  • Low-cost and scalable

  • Community-driven

  • Scientifically validated

  • Policy-relevant

👉 Strong potential for replication across Mauritius and the region

Conclusion

The Le Morne VMCA project demonstrates that community-led conservation, when supported by strong scientific expertise, can deliver measurable ecological and socio-economic impact. Through the joint implementation by CGC and EMCL, this initiative has successfully protected critical seagrass ecosystems, empowered local communities, and established a scalable model for marine conservation. It provides a powerful example of nature-based solutions for climate resilience in Small Island Developing States (SIDS).
