There are over 600 young people of over 50 nationalities involved in this project, aged 11 to 14 (both children and adolescents), speaking at least eight languages between them. Many are refugees and migrants, most are from marginalised communities. How can we genuinely enable their participation in one small book? Nicky Parker, from Amnesty International Poland, runs us through their philosophy and how this will be integrated in Seen and Heard.
