The document titled "Best Practices, Measures and Lessons Learnt for Biodiversity Restoration, Ensuring Carbon Sink Optimization and Buffering Resilience to Climate Extremes" provides an in-depth overview of the challenges and strategies for restoring marine ecosystems in the Mediterranean Sea. The Mediterranean is a biodiversity hotspot, home to numerous endemic species, yet it faces significant pressures from pollution, overfishing, and habitat destruction due to heavy human activity. Restoration of these ecosystems is critical not only for the preservation of species and habitats but also for ensuring the continued provision of vital ecosystem services such as carbon sequestration, nutrient cycling, and climate regulation. These efforts align with the goals of the UN Decade on Ecosystem Restoration 2021–2030, a global initiative aimed at preventing, halting, and reversing ecosystem degradation to ensure a sustainable future for both people and nature. Drawing on decades of restoration efforts, this document highlights best practices and lessons learned from various initiatives focused on restoring endemic species and habitats. These insights are key to scaling up restoration efforts globally. They inform public policies, guide Marine Protected Area managers, and assist decision-makers in creating frameworks that promote ecological resilience and sustainable use of marine resources. Furthermore, they provide environmental groups and scientists with actionable strategies for advancing restoration science.
Key restoration projects, such as those targeting seagrass meadows, algal forests, and coralligenous reefs, offer valuable models for replication. These projects demonstrate that successful restoration requires adaptive management, collaboration among stakeholders, and long-term investment, also in the monitoring programs. By applying these lessons, the global marine restoration community can strengthen resilience to climate extremes and optimize the role of marine ecosystems as carbon sinks, contributing to both local and planetary health.
