Pilot 2
Protecting vital wetland‑to‑sea ecosystems in the Western Mediterranean
~320 km²
Protected Areas
Natura 2000
Conservation Status
UNESCO
Biosphere Reserve
A Key Coastal Biodiversity Hotspot
The Ebro Delta Bays are a highly significant Mediterranean estuarine system, supporting diverse life from seagrass meadows to endangered species like Pinna nobilis. The area is protected under EU directives, the Ramsar Convention, and UNESCO Biosphere Reserve status. Biosphere Reserve status.
Rich Marine Life
Diverse coastal and lagoon habitats support priority species and ecological processes important for migratory birds and marine biodiversity.
EU Protected
Designated as Natura 2000 and integrated into multiple EU environmental frameworks including Water Framework and Marine Strategy Directives.
Long-term Data
Existing monitoring programs provide critical data on water quality, species abundance, and sediment conditions, essential for understanding ecosystem health.
Current Challenges
Water Quality Decline
Intensive rice agriculture and drainage discharge elevate nutrient loads, turbidity, and contaminants, degrading marine habitats and water quality.
Habitat Degradation
Accumulated sediments, low oxygen levels, and disrupted substrates compromise seagrass beds, coastal lagoons, and benthic communities.
Climate Impacts
Rising water temperatures, acidification, and sea‑level pressures further exacerbate ecosystem stress and loss of sensitive species.
Restoration in Action
Natural Filtration & Habitat Recovery
Establish helophytic coastal plant communities to filter rice discharge and improve water conditions Remove accumulated muds in shallow bays to support seagrass (Cymodocea nodosa) recovery and substrate health
Artificial Biotopes & Species Control
Install designed biotopes near aquaculture areas to encourage ecological community shifts Encourage predator populations to help control invasive species like the Blue Crab (Callinectes sapidus)
Oxygenation Systems
Pilot test systems to increase dissolved oxygen, combating low‑oxygen conditions driven by warming and eutrophication.
Expected Impact
Biodiversity Recovery
Enhanced water quality and habitat conditions will support increased species abundance and diversity.
Habitat Quality
Seagrass and benthic community revitalization will improve ecosystem function and resilience.
Climate Resilience
Actions will help buffer ecosystems against warming, acidification, and sea‑level rise.
Blue Economy Benefits
Improving environmental conditions also supports aquaculture, tourism, and coastal livelihoods.
Community Engagement
Local and regional participation is central to Pilot 2’s success:
Co‑creation & Governance
Restoration and management strategies are co‑designed with stakeholders through the Ebro Bioterritory Living Lab.
Education & Citizen Science
Engagement with local students and volunteer programs Activities under initiatives like Blue Schools, Sea Watchers, and citizen monitoring platforms to connect communities with marine science and stewardship.
