CRC/C/NGA/CO/3-4 53. The Committee recommends that the State party provide further information about the implementation of article 21 of the Convention in its next periodic report. The State party is strongly encouraged to harmonize national laws on domestic adoption with the Child Rights Act and ensure their compliance with the Convention, including with kafala. While recalling that inter-country adoption is a measure of last resort for children without families, the State party is urged: (a) To ratify the 1993 Hague Convention on Protection of Children and Cooperation in Respect of Inter-country Adoption; (b) To continue its efforts to eradicate the existence of “baby farms”, including by concluding its mapping exercise on “baby farms”, ensuring the release and rescue of child victims of this practice and investigating and prosecuting those responsible. Abuse and neglect 54. While noting the acknowledgment of the State party about the abuse of children in street situations, especially sexual harassment, and in the family setting, the Committee regrets the lack of information about the extent and forms of child abuse and about the legislative and administrative framework in place to prevent and protect children from all forms of violence, abuse and neglect. 55. The State party is urged: (a) To put in place an effective system of data collection and monitoring cases of violence, abuse and neglect of children; (b) To establish an effective coordination mechanism between authorities competent to receive and investigate child abuse cases, including the special units, pilot juvenile complaint desks and human rights desks of the Nigerian Police and the Special Rapporteur on Child Rights of the Nigerian Human Rights Commission; (c) To undertake comprehensive training and sensitization programmes for health professionals, law enforcement personnel, judges and prosecutors on the prevention, protection and prosecution of child abuse cases.

The Committee is furthermore concerned at the lack of information on follow-up on its previous recommendations relating to children with disabilities (CRC/C/15/Add.257, paras. 46-47), in particular that no comprehensive policy on children with disabilities has been developed. The Committee furthermore notes the use of offensive and derogatory definitions and categories employed by the State party when referring to children with disabilities. 57. The Committee urges the State to take measures towards the ratification of the Convention on the Rights of Persons with Disabilities and to take all necessary measures to implement its earlier recommendations regarding children with 13
