CRC/C/CRI/CO/4 investment in these sectors, which is likely to affect the quality of the environment (e.g. quality of water and soil), property rights and family life. 26. The Committee urges the State party to extend to other sectors beyond tourism a regulatory framework to ensure that activities of the corporate sector, both national and foreign, do not impact negatively on children and to give due consideration to experiences from around the world in the application of, inter alia, the Business and Human Rights Framework adopted by the Human Rights Council to the operations of private and public corporations, particularly in relation to child rights. B. Definition of the child (art. 1 of the Convention) 27. While noting the adoption by the State party in 2007 of Act No. 8571 amending the Family Code and the Civil Code that prohibits marriage under 15 years of age, the Committee is concerned that children aged 15–18 may get married with their parents’ consent. It also notes with concern that the very low minimum age of sexual consent of 13 years increases children’s risk of sexual abuse and early pregnancy. 28. The Committee recommends that the State party raise the minimum age of marriage to 18 and review the age of sexual consent, with a view to ensuring the healthy development of children, preventing forced marriage, early pregnancies and sexual abuse. C. General principles (arts. 2, 3, 6 and 12 of the Convention) Non-discrimination 29. The Committee remains concerned about continued discriminatory attitudes and prejudices against indigenous children, children of African descent, Nicaraguan and other migrant children. The Committee also remains concerned about growing disparities affecting indigenous children with regard to access to health care (child mortality being twice as high as the national average) and education (illiteracy being six times higher than the national average), especially in rural and coastal areas. While welcoming the new Migration Act, the Committee regrets that the State party has decided not to ratify the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families. 30. The Committee recommends that the State party: (a) Strengthen its efforts to eliminate societal discrimination and prejudice against indigenous, Afro-descendant, migrant children and children with disabilities through legislative measures, awareness-raising programmes, the media and the educational system, as well as in-service training for public officials; (b) Adopt a comprehensive action plan for indigenous children, including targeted programmes and investment in services and infrastructure in indigenous territories and rural and deprived urban areas in order to improve the socio-economic situation of indigenous and other minority children, taking into account the Committee’s general comment No. 11 (2009) on indigenous children and their rights under the Convention; and (c) Inform children who are affected by societal discrimination and prejudice about their rights under the Convention. 31. The Committee requests the State party to include information in its next periodic report on measures and programmes relevant to the Convention on the 6
