MED-JELLYRISK is the first CBC (Cross-Border Cooperation) project assessing the socio-economic impacts of jellyfish blooms and the implementation of mitigation countermeasures. MED-JELLYRISK addresses an integrated coastal management approach into 10 Marine Coastal Zones (MCZs) in the western and central Mediterranean Sea basins faced with increased jellyfish proliferations. In these areas, jellyfish outbreaks represent a growing threat for humans and coastal activities (including leisure and aquaculture). The strategic objective is the promotion of joint planning methodologies. In particular, the project will promote the implementation of risk assessment, prevention and mitigation of negative impacts resulting from jellyfish proliferations in the 10 MCZs.
