Mutual knowledge transfer is the second cornerstone of our international work. From our point of view, transnational cooperation works more effectively and sustainably when they are run in a joint collaborative process: Even though we already have many years of expertise in deradicalisation work, the respective cooperation partners are experts for the local matters. Only when both sides work together can an effective work approach be developed for specific local and situational circumstances. We are currently cooperating with the Generalitat de Catalunya in the Preventing Radicalisation through Probation and Release (PREPARE) project. Through coaching and participation in conferences and workshops we also want to share our expertise, learn from other approaches and share ideas across borders. To promote a European approach, we emphasise two-way knowledge transfer and open discussions about different methods and approaches. Therefore, we present and discuss our work regularly, e.g. on behalf of the Federal Foreign Office abroad, at conferences and in front of international delegations. Through training sessions and workshops we support and qualify local organisations in the fields they desire.
