CRC/C/15/Add.124 page 13 situation, declining school enrolment and attendance rates, and the increasing number of children living and/or working on the streets, the Committee is concerned about the lack of information and adequate data on the situation of child labour and economic exploitation within the State party, including in the informal sector. Concern is also expressed at the significant number of children begging on the streets and their vulnerability to exploitation and abuse. 61. The Committee encourages the State party to introduce monitoring mechanisms to ensure the enforcement of labour laws and protect children from economic exploitation, particularly in the informal sector. The State party is encouraged to continue its cooperation with IPEC to finalize, by the end of 2000, a child labour survey to assess the situation of children in this regard. The Committee encourages the State party to consider ratifying the ILO Worst Forms of Child Labour Convention, No. 182. Children living and/or working on the streets 62. Concern is expressed at the large and increasing number of children living and/or working on the streets. 63. The Committee recommends to the State party to establish mechanisms to ensure that children living and/or working on the streets are provided with identity documents, food, clothing and housing. Moreover, the State party should ensure that these children are provided adequate access to health care, rehabilitation services for physical, sexual, and substance abuse, protection from police brutality, services for reconciliation with their families and education, including vocational and life-skills training. The Committee recommends to the State party to cooperate and coordinate its efforts in this regard with civil society. Drug abuse 64. The Committee is concerned at the increasing incidence of drug, alcohol and substance abuse among youth as well as the lack of financial and human resources, inadequate monitoring mechanism and insufficient psychological, social and medical programmes and services available in this regard. 65. In light of article 33 of the Convention, the Committee recommends that the State party take all appropriate measures, including administrative, social and educational measures, to protect children from the illicit use of alcohol, narcotic drugs and psychotropic substances and to prevent the use of children in the illicit production and trafficking of such substances. It encourages the State party to support rehabilitation programmes dealing with child victims of alcohol, drug and substance abuse. In this regard, the Committee encourages the State party to consider seeking technical assistance from UNICEF, WHO, the United Nations International Narcotics Control Board, among others.
