The project in briefThe Mediterranean coasts are facing increasing jellyfish outbreaks resulting from a wide variety of human activities including maritime transport, exploitation of living resources, discharges together with the impact of climate change. Jellyfish proliferation represents a growing threat for human and coastal activities (mainly leisure and aquaculture). Every summer 2 million bathers are affected by jellyfish stings meaning high cost of basic first aid treatments for the national health services. The situation has worsened over the last years due to the apparition of new dangerous varieties. Against the threat posed by jellyfishes for tourism in the Mediterranean area, MED-JELLYRISK constitutes the first-ever attempt at cross-border level in order to assess the socio-economic impacts of jellyfish blooms and implement mitigation countermeasures. Specific objectiveTo promote a cross-border approach in 10 selected Mediterranean Coastal Zones (MCZ) to assess, prevent, mitigate and foresee the negative natural, health and economic impacts of jellyfish proliferations. Expected Results: • Protecting nets, info panels, and first aid kits supplied and installed in 20 Mediterranean coastal sites • Reduction of adult jellyfish abundance achieved (at least 75%) in safe bathing areas with respect to unprotected areas • Human and climate-related jellyfish proliferation emergencies and hazards identified and assessed across MCZs from Spain, Italy, Malta and Tunisia • Risk mapping and shared databases for jellyfish proliferations set up, updated and applied by stakeholders to rank water quality and safety areas in MCZs • Concerned stakeholders in the MCZs trained and capable to apply integrated jellyfish monitoring protocols • Risk of jellyfish impacts understood by general and professional public in the operations areas
