CRC/C/GC/21 necessary for the child’s optimal development (arts. 5, 18 and 27). States should also support civil society, as complementary actors, in providing personalized, specialist services for children in street situations the basis of a child rights approach, through funding, accreditation and regulation. The business sector must meet its responsibilities regarding children’s rights, and States should ensure it does so. 8 Coordination is needed between State and non-State actors. States are legally obliged to ensure that non-State service providers operate in accordance with the provisions of the Convention. 9 Addressing complexity 16. Strategies need to address multiple causes, ranging from structural inequalities to family violence. They also need to take into account measures for immediate implementation, such as stopping round-ups or the arbitrary removal of children from public spaces, and measures to be implemented progressively, such as comprehensive social protection. A combination of legal, policy and service provision changes is likely to be needed. States should commit to fulfilling human rights beyond childhood. Particularly, States should ensure follow-up mechanisms for children in alternative care settings and in street situations as they transition into adulthood at the age of 18, to avoid an abrupt termination of support and services. Comprehensive child protection systems 17. Within a legislative and policy framework, budgeting for, developing and strengthening holistic child protection systems, on the basis of a child rights approach, forms the basis of the practical measures required for prevention and response strategies. Such national child protection systems need to reach children in street situations and should incorporate fully the specific services they need. The systems need to provide a continuum of care across all relevant contexts, including prevention, early intervention, street outreach, helplines, drop-in centres, day-care centres, temporary residential care, family reunification, foster care, independent living or other short- or long-term care options. However, not all of these contexts are relevant for all children in street situations. For example, prevention and early intervention are priorities for children at the early stages of developing strong and harmful street connections, but are not relevant for children born in street situations. Some children may not experience residential placements while, for others, family reunification is not relevant or appropriate. Strategies should make it clear that a child rights approach needs to apply to each and every context. Administrative burdens and delays in gaining access to child protection systems should be reduced. Information should be made available in child-friendly and accessible formats and children in street situations should be supported to understand and navigate child protection systems. Capacity-building of those in contact with the child 18. States should invest in good quality initial and in-service basic training on child rights, child protection and the local context of children in street situations for all professionals who may come into direct or indirect contact with children in street situations, in such areas as policymaking, law enforcement, justice, education, health, social work and psychology. This training may draw on the expertise of non-State actors and should be integrated into the curricula of relevant training institutions. Additional in-depth training on a child rights approach, psychosocial support and child empowerment is required for professionals working with children in street situations as a dedicated part of their mandate, for example, street-based social workers and specialized child protection units of the police service. “Outreach walks” and “street walks” are an important on-the-ground training method. Basic and specialized training should include attitudinal and behavioural change, as well as knowledge transfer and skills development, and should encourage intersectoral cooperation and collaboration. National and local governments should understand and 8 9 See general comment No. 16 (2013) on State obligations regarding the impact of the business sector on children’s rights, para. 8.
