The European context of this project is economies providing few jobs for young people since the 2008 recession, barriers to higher education, and populist politics with harsh side-effects for new Europeans. It is difficult for a young person to find purpose in this context, and to get drawn into radicalization. On the African continent, risk of radicalisation may be zero in one country and deter travelers in another. Youth are bribed/blackmailed into radical groups to fill ranks, or triggered into radicalism by perceptions of injustice, hopelessness, religiously-inspired indignation, hunger, and dislocation.Underlying this project is the EC-funded Radicalization Awareness Network’s finding that the best way to prevent radicalization in young people is to divert their attention and engage them in self-reinforcing activities; also stresses the need for closer links between local government and youth NGOs youth workers covering the “last mile” to the radicalism candidate.“Horizontal Youth Engagement to Prevent Radicalization” (HYEPR) is the natural result of something common to all of the NGOs listed here: deep engagement in youth work, and equally deep concern with growing numbers of young people who are having identity crises, or who cannot find their place in the European economies of today, facing high levels of unemployment with few opportunities to become apprenticed, and reduced social services to support them in the effort to find that place and that identity.HYEPR aims to build up the capacities of European and East African youth work NGOs so they can face youth radicalization with innovative and attractive tools, resilient management, and a sense of their ethical boundaries. In order to meet this objective, this project draws into partnership the most dedicated NGOs doing radicalization prevention, and the most innovative informal education designers.The partners research all tools used in youth work in the 7 countries, also letting peer NGOs know about this anti-radicalization initiative. Partners present tools, groups learn how they work, and select the 21 tools and activities for the Meta-Toolkit, accompanied by a best practices Handbook for global dissemination and trainings. 28 youth workers do intensive training to become Meta-Toolkit trainers who will train 560 other youth workers in their countries. Project leverages mobility and capacity-building events to improve linkage and local government’s recognition of the value of youth work. Five international events/mobilities over 24 months allow partners to help each other strengthen organization, improve governance, fundraising and capacity for innovative thinking. This project generates intense phases of group activity to turn partners into a pioneer group of informal learning tailored to radicalization.
