CRC/C/GC/13 (a) Human resources: improved communication, cooperation and individual exchange within and between professional associations (for example medical, mental health, social work, legal, education, child maltreatment, academic/research, child rights and training organizations/institutions); improved communication and cooperation within and between civil society groups (for example research communities, NGOs, child-led organizations, faith-based organizations, organizations of persons with disabilities, community and youth groups, and individual experts involved in the development and exchange of knowledge and practice); (b) Financial resources: improved coordination, monitoring and evaluation of donor aid; further development of financial and human capital analyses in order for economists, researchers and States parties to fully measure the costs of implementing holistic child protection systems (with an emphasis on primary prevention) versus the costs of managing the direct and indirect (including intergenerational) impact of violence at the individual, community, national and even international levels; and reviews by international financial institutions of “their policies and activities to take account of the impact they may have on children”; 28 (c) Technical resources: evidence-based indicators, systems, models (including model legislation), tools, guidelines, protocols and practice standards for use by communities and professionals, with guidance on their adaptation to different contexts; a platform for systematic sharing and accessing of information (knowledge and practice); universally established clarity and transparency in budgeting for child rights and child protection, as well as in outcome monitoring of child protection during up and down cycles of economies and challenging circumstances (technical assistance should be established over time, through information, models and related training). 76. Regional and international cross-border cooperation. In addition to development assistance, cooperation is also needed to address child protection issues which cut across national borders such as: cross-border movement of children – either unaccompanied or with their families – either voluntarily or under duress (for example due to conflict, famine, natural disasters or epidemics) which can put children at risk of harm; cross-border trafficking of children for labour, sexual exploitation, adoption, removal of body parts or other purposes; conflict which cuts across borders and which may compromise a child’s safety and access to protection systems, even if the child remains in the country of origin; and disasters that impact several countries simultaneously. Specific legislation, policies, programmes and partnerships may be required to protect children affected by cross-border child protection issues (for example cybercrime and extraterritorial prosecution of those who sexually abuse children through travel and tourism and traffickers of families and children), whether these children are in traditional caregiving situations or where the State is the de facto caregiver, as in the case of unaccompanied children. 28 A/61/299, para. 117. 29
