The PREP4BLUE Plan for the Dissemination and Exploitation including Communication Activities (PDEC) outlines the EC rights and obligations of the consortium related to exploitation, dissemination, and communication of project results. It adopts EC best practice guidelines and defines the objectives of PREP4BLUE’s plans for communication, dissemination, and exploitation. It also identifies target stakeholders, proposes communication tools and channels, and outlines responsibilities and resources to carry out effective knowledge management and to measure impact of activities carried out. The PDEC has been developed by ERINN Innovation, who will also oversee its continuous implementation. This is the first version of the PDEC, and it will be updated regularly throughout the project.
