A/HRC/43/39 115. Substantial additional investments are required for promoting and protecting mental health. Although additional resources are essential, an immediate opportunity exists for efficient and effective use of existing resources. That could include, for example, the redistribution of mental health budgets from large hospitals to district hospitals and community-based local services; the introduction of early interventions for emerging mental disorders; and the reallocation of budgets for other health priorities to promote the integration of mental health care into established platforms of delivery. 116. Investments in research and innovation should also continue to grow. The imbalance whereby most research is conducted in and by high-income countries needs to be corrected in order to ensure that low- and middle-income countries have culturally appropriate and cost-effective strategies to respond to mental health needs and priorities. The crucial information needed to take effective action includes the prevalence and nature of mental health problems; coverage of policies and legislation, interventions and services; health outcome data; and social and economic outcome data. Those data need to be disaggregated by sex and age and reflect the diverse needs of subpopulations, including individuals from geographically diverse communities and vulnerable populations. 117. Finally, as the international community looks ahead to the decade of action for the Sustainable Development Goals, delivery for sustainable development, monitoring and accountability frameworks must be put in place to ensure that effective action is being taken to promote the mental health of all, prevent mental disorders among children who experience violence and others at high risk, and provide treatment and care to those who need it. V. Looking forward 118. Since assuming her role in July 2019, the Special Representative has developed her strategy for this mandate period through a consultative and participatory process. The new strategy includes three priority areas: (a) advocacy and mobilization of all key stakeholders at the global, regional and national levels for the accelerated implementation of target 16.2 of the Sustainable Development Goals and of other related Goals; (b) ensuring that all forms of violence are included in the implementation of the 2030 Agenda for Sustainable Development, thereby ensuring that no child is left behind; and (c) amplifying the voices of children, with particular attention paid to the most vulnerable. 119. Effective cooperation between the many actors in this field is critical. Children’s lives are not divided thematically to correspond to the mandates of the organizations working on their behalf: they are often exposed to more than one form of violence and in more than one setting. Mobilizing partnerships at all levels and involving all stakeholders is essential to generate the necessary resources and spur action. The Special Representative will use a participatory and consultative approach to support cooperation and constructive dialogue with all relevant stakeholders at the national, regional and international levels to respond effectively to the continuum of violence that child victims face. 120. The most important partners in ending violence are children themselves. The active and meaningful involvement of children in identifying the challenges to sustainable development and how to overcome them both realizes their right to participation and provides an effective way to accelerate progress. The Special Representative will pursue close collaboration with child-led and child-focused organizations to ensure that the mandate amplifies children’s voices and takes their views fully into account. Particular attention will be paid to including the most invisible and vulnerable children in order to ensure that no child is left behind. 21
