CRC/C/15/Add.99 page 3 9. While noting the efforts of the National Committee for Families and Children in facilitating the coordination and monitoring of child rights issues, the Committee is concerned that involvement and coordination at the local level are still somewhat limited. The Committee is also concerned that the State party has not yet implemented its National Plan of Action for Children or its National Plan of Action for Human Development. The Committee recommends that the State party seek to use a comprehensive approach to the implementation of the Convention by, inter alia, ensuring the introduction of measures at the local level to promote and protect children's rights. The Committee also recommends that further steps be taken by the State party to strengthen its coordinating efforts through the National Committee for Families and Children, particularly at the local level. The Committee also encourages the State party to implement its National Plan of Action for Children and the National Plan of Action for Human Development. 10. The Committee notes the recent formation of a Social Indicators Committee responsible for monitoring quality data collection throughout the State party and ensuring its comprehensive analysis. The Committee is still concerned, however, that the current data-collection mechanism is insufficient to afford the systematic and comprehensive collection of disaggregated quantitative and qualitative data for all areas covered by the Convention in relation to all groups of children in order to monitor and evaluate progress achieved and assess the impact of policies adopted with respect to children. The Committee recommends that the system of data collection be reviewed with a view to incorporating all the areas covered by the Convention. Such a system should cover all children up to the age of 18 years, with specific emphasis on those who are particularly vulnerable, including children with disabilities; children belonging to minority and indigenous groups, such as Maya and Garifuna children; children living in remote rural areas; children living in poverty; children living and/or working on the street; refugee and asylum-seeking children; illegal immigrant children; children in the juvenile justice system; children of single-parent families; children born out of wedlock; sexually abused children; and institutionalized children. 11. The Committee also expresses concern at the absence of an independent mechanism to register and address complaints from children concerning violations of their rights under the Convention. The Committee suggests that an independent child-friendly mechanism be made accessible to children to deal with complaints of violations of their rights and to provide remedies for such violations. The Committee further suggests that the State party undertake an awareness-raising campaign to facilitate the effective use by children of such a mechanism. 12. The Committee notes the impact of economic policies and the structural adjustment programme which have had adverse effects on social investment. The Committee remains concerned, in the light of article 4 of the Convention, that not enough attention has been paid to allocating budgetary resources in favour of children to the maximum extent of available resources. In the light of articles 2, 3 and 6 of the Convention, the Committee encourages the State party to pay particular attention to the full implementation of article 4 of the Convention by prioritizing budgetary allocations to ensure implementation
