Street children 83. The Committee reiterates its grave concern at the high number of children living in the streets and their special vulnerability to various forms of violence and abuse, including sexual abuse and exploitation, economic exploitation and substance abuse. The Committee notes the lack of a systematic and comprehensive strategy to address the situation and protect children living in the streets. The Committee emphasizes that unlawful arrest and detention of street children are serious violations of the provisions and principles of the Convention. Notwithstanding the efforts taken by the State party and, in particular, many non-governmental organizations working with and for street children, for example ChildHope Asia Philippines, the Committee is concerned about street children’s limited access to adequate nutrition, clothing, housing, social and health services and education. Furthermore, the Committee is concerned about health risks faced by street children, including environmental health risks, such as toxic and hazardous wastes and air pollution.
