As part of the transferring activities of PB MPAs project, a regional capacity building event will be organized in Dubrovnik and Lokrum (Croatia), to transfer the knowledge gained on harmonized Marine Litter monitoring approaches to key Mediterranean stakeholders. Such training will primarily target MPA managers, although representatives of competent authorities, academia and NGOs might also participate. This training will focus on how to carry out ML surveillance and aims at developing attendees' skills to design an effective ML monitoring program that is consistent with the MSFD and the Barcelona Convention frameworks.
