In order to communicate with the external environment and promote the project results and achievements, communication plays an important role during the NATMed project lifetime and beyond (legacy). The communication and dissemination of the NATMed project activities, advances and results play a crucial role for the overall success of the project. They set the ground for future exploitation and sustainability of the project results and develop a clear understanding of the value stemming from the project outputs. This document, D6.4 – D6.5 Communication & Dissemination Impact Report (first version), aims to detail all the dissemination, communication and outreach activities that have been implemented within the NATMed project from M1 until M18. As described in D6.1 Communication, Dissemination and Exploitation (CDE) Plan which elaborates on the communication and dissemination strategy of the NATMed project, the consortium partners engage in several dissemination and communication activities throughout the project to ensure the visibility, dissemination and exploitation of the findings of NATMed across the project’s target groups. In order for the dissemination planning and methodology to be effective, a co-designed programme of activities has been implemented, based on the profiles of the target audiences, highlighting the benefits and results delivered to stakeholders, and ensuring their active involvement in the activities of the project. These activities include workshops, networking events, conferences, training sessions, press releases, newsletters, scientific publications, social media posts and more and they are presented in detail in the following chapters. This version is delivered by M18 and will be further reviewed, fine-tuned and adjusted according to the project’s needs by M36 through its final version.
