A/74/136 142. States should develop and apply a tailored and individual case management approach to children associated with non-State armed groups designated as terrorist. 143. The Independent Expert further recommends that States take responsibility for child nationals who may be detained for security-related offences or association with armed groups, including children born to their nationals. States should take measures to prevent children from becoming stateless and, on the basis of the child’s best interests, facilitate the child’s return to their country of origin for rehabilitation, reintegration and/or prosecution, as appropriate, in full compliance with international law. C. Follow-up 144. The Independent Expert calls upon the General Assembly to ensure the development and maintenance of an international database containing all relevant data on children’s deprivation of liberty. In developing such a database, a common methodology, based on the study, needs to be applied in order to enhance comparative research. 145. States are encouraged to establish focal points who regularly collect reliable data on all situations of children deprived of liberty per year and on a “snapshot” date. 146. States are urged to develop national action plans aimed at an overall reduction in the numbers of children in detention and/or the elimination of detention for children. 147. As deprivation of liberty constitutes a form of structural violence against children, the Independent Expert recommends that the detention rate of children in all situations covered by the study be considered in the implementation of target 16.2 of the Sustainable Development Goals. 148. The phenomenon of the deprivation of liberty of children must remain on the agenda of the General Assembly, the Security Council and the Human Rights Council. All United Nations agencies, mandates and special mechanisms are called upon to play an active role in the implementation of the recommendations provided by the global study. The Independent Expert calls upon the General Assembly to consider appropriate and effective follow-up mechanisms aimed at disseminating the study findings and promoting its recommendations at the international, regional and national levels. 19-11838 23/23
