CRC/C/GC/21 situations. Key issues to address include: improving rights-based community development in impoverished neighbourhoods; establishing comprehensive economic and social safety nets; providing safe and affordable day-care centres and other specialist services; and improving access to adequate housing and income generation for families. In addition to structural and policy approaches, vulnerable families need case-by-case solutions facilitated by well-trained professionals. States should invest in and scale up family support programmes on the basis of a child rights approach that are proved to halt the intergenerational transmission of conditions that exacerbate children ending up in street situations. States should take measures to provide universal education on child rights and positive parenting for all parents and caregivers, prioritizing — in a non-stigmatizing way — families with children at risk of ending up in street situations. This education should include child rights, including how to listen to children and include their views in decisionmaking; positive child-rearing, including positive discipline skills, non-violent conflict resolution and attachment parenting; and early childhood development. See also paragraphs 35 and 49. D. Adequate standard of living Article 27 on the right to an adequate standard of living Support to parents, caregivers and children 49. In accordance with article 27 (3), States should ensure that all children have a standard of living adequate for their physical, mental, spiritual and moral development, to prevent them ending up in street situations and to fulfil the rights of children already in street situations. States shall take appropriate measures to assist parents and others responsible for the child to implement this right and shall in case of need provide material assistance and support programmes, particularly with regard to nutrition, clothing and housing. Those prescriptions leave no leeway for the discretion of States. The implementation of the above in accordance with national conditions and within the means of States parties should be interpreted in conjunction with article 4, that is, to the maximum extent of States parties’ available resources and, where needed, within the framework of international cooperation, with particular regard to the obligations of States to fulfil the minimum core obligation for social, economic and cultural rights. In terms of material assistance, children in street situations prioritize the need for a safe place to live, food and free and accessible medical care and education, through State support to parents and caregivers, particularly in relation to subsidized, adequate housing and income generation. The interpretation of article 27 (3) is not limited to measures to assist parents and others responsible for the child. The obligation to provide material assistance and support programmes in case of need should be interpreted as also meaning assistance provided directly to children. This is particularly relevant for children in street situations with nonexistent or abusive family connections. Direct material assistance to children in the form of services may be provided either by the State or via State support to civil society organizations. For single-parent and reconstructed families, States’ measures to secure maintenance for the child are particularly important (see article 27 (4)). Adequate housing 50. The right to housing is an important component of article 27 that is particularly relevant for children in street situations. It has been interpreted broadly by the Committee on Economic, Social and Cultural Rights as the right to live somewhere in security, peace and dignity,45 which clarifies that the concept of “adequacy” in relation to housing requires attention to: legal security of tenure; availability of services, materials, facilities and infrastructure; affordability; habitability; accessibility; location; and cultural adequacy. 46 Children are among those who suffer disproportionately from the practice of forced 45 46 See Committee on Economic, Social and Cultural Rights, general comment No. 4 (1991) on the right to adequate housing, para. 7.
