The report highlights the practical experience of different stakeholders. Firstly, a number of lessons learned are based on DRC’s experience of implementing a return and reintegration assistance programme for rejected asylum seekers from Kosovo in Denmark and Kosovo. Secondly, a series of studies and assessments have been conducted in Denmark, Germany and Kosovo, assessing the impact of different support and reintegration measures. Finally, discussions with NGOs, institutions and authorities in the Balkans and Western Europe have been facilitated through international conferences and workshops, exploring differing perspectives on the measures needed to achieve sustainable return. As a result of the contributions presented in this report, recommendations for best practices in NGO-assisted mandatory return have been developed.
