Project description

TERRA is a Europe-wide network-based prevention and learning project, funded by the European Commission, DG Home Affairs. The lead partner is Arq Psychotrauma Expert Group in the Netherlands.

Created using state of the art research and consultations with frontliners, academic experts, victims of terrorism and former extremists, it proposes a community approach designed to address the grievances which form the motivation for radicalisation, identify and halt the progress of an individual on a path to radicalisation, and prevent them from undertaking a terrorist act.

The TERRA Toolkit is primarily intended to support existing or new networks of teachers, youth workers, law enforcement officers, religious leaders and local policy-makers as they exchange information on young people at risk of radicalising, and to come to a weighted judgment on the risks. It also informs journalists and policy-makers on influences they may have on the background factors that lead to radicalisation.

The TERRA Toolkit is aimed at professionals Europe-wide, and addresses all common forms of extremism: right-wing extremism, left-wing extremism, Islamist extremism, separatism and single-issue extremism. One tool – the one for religious leaders – focuses only on Islamist extremism.


The toolkit comprises:

  • a general background document which covers the objectives, presuppositions and starting points, implications for use and implementation;
  • separate tools for each target group with manuals on the indicators of radicalisation and tip sheets;
  • video material showing testimonials from victims of terrorism, former radicals and interviews with representatives of the different target groups.
