CRC/C/SLV/CO/3-4  Ensure accountability and end impunity;  Address the gender dimension of violence against children; and  Develop and implement systematic national data collection and research. (b) Use these recommendations as a tool for action, in partnership with civil society and in particular with the involvement of children, to ensure that every child is protected from all forms of physical, sexual and psychological violence and to gain momentum for concrete and, where appropriate, time-bound actions to prevent and respond to such violence and abuse; (c) Seek technical cooperation in this respect from, inter alia, the Special Representative of the Secretary-General on Violence against Children, OHCHR, UNICEF and WHO and other relevant agencies, as well as NGO partners. 5. Family environment and alternative care (arts. 5; 18, paras. 1-2; 9-11; 19-21; 25; 27, para. 4; and 39 of the Convention) Family environment 46. The Committee welcomes the approach contained in the LEPINA which recognises and strengthens the fundamental right of the child and adolescent to live, be brought up and develop in the nuclear or extended family of origin. According to the new Law, family separation may only take place in exceptional cases; it also clearly establishes the shared responsibility of the family, the State and society in complying with these rights. The Committee, however, is concerned that for different reasons, including the weakening of the social fabric at community level, the absence at local level of policies to strengthen families, parental irresponsibility and migration abroad, many children live without one or both parents and are left without the necessary support and care. 47. The Committee encourages the State party to: (a) Continue promoting responsible motherhood and fatherhood, including by strengthening the mechanisms to verify the provision of maintenance allowances, as well as by effectively implementing the existing legislation, which should be strengthened with the entry into force of LEPINA; (b) Consider becoming a party to the 1973 Hague Convention No.23 on the Recognition and Enforcement of Decisions relating to Maintenance Obligations; (c) Develop comprehensive family services and support programmes such as family counselling, parental training, home visit and family recreation programmes in every community; (d) Strengthen social protection networks at local level; (e) Establish orientation and support programmes at local level for families affected by migration; (f) Implement the recommendation made recently by the Committee on Migrant Workers (CMW/C/SLV/CO/1) to finalize the study on the impact of migration on children. The findings of the study should be widely disseminated with a view to developing adequate strategies to ensure the protection and the full enjoyment of rights by children affected by migration; (g) Seek assistance from, inter alia, UNICEF in this respect. 11
