The main goal of this seminar, organised by the European Confederation of Youth Clubs - ECYC, is to set up a series of exchanges between youth workers and youth policy stakeholders to present and discuss the needs of youth workers in the prevention of processes of youth radicalisation leading to violent extremism. During a full four day meeting in Brussels, youth workers will have the chance to re-view work dedicated to this topic, exchange ideas and practices, and formulate key messages for the use of youth policy actors at European level.
