A/67/256 communities. Systematic data collection and analysis of the human cost of these weapons is critical to the development of baseline information, which would in turn further strengthen the empirical basis for advocacy efforts to better protect children. In the context of the monitoring and reporting mechanism on grave violations against children, the Office of the Special Representative will, together with United Nations partners, endeavour to gather disaggregated and more detailed information on child casualties resulting from the use of such weapons. The Office will also advocate the inclusion of specific provisions against the use of explosive weapons in action plans signed by parties to conflict that aim at halting the killing and maiming of children. IV. Recommendations for the way forward 65. The Special Representative urges Member States to enact appropriate national legislation to criminalize grave violations against children, including the recruitment and use of children in armed forces and armed groups, which has been defined in the Rome Statute as a war crime, and also to bring adult recruiters to justice in national courts. In this regard, the international community should support Member States, where appropriate, to develop and strengthen national capacity for the administration of justice. 66. International and national courts are encouraged to use and build on the jurisprudence arising from the judgement handed down by the International Criminal Court in the Lubanga case and to be guided by the measures that the Court has put in place related to child protection and child participation in judicial proceedings. 67. The Special Representative, encouraged by the continuing efforts of regional organizations to develop measures to ensure the mainstreaming of child protection concerns in activities related to conflict prevention, mediation and peace support operations, calls upon these regional organizations to fully implement the guidance developed. 68. In addition, the Special Representative encourages further engagement on the children and armed conflict agenda by other regional organizations with a view to developing awareness of and political commitment to the agenda, in addition to, where relevant, appropriate policy and operational guidance. 69. With regard to the use of explosive weapons in populated areas, the Special Representative urges Member States to take steps to reduce the impact of such weapons on children, including by: (a) Refraining from using explosive weapons with wide-area effect in populated areas, including by revising and strengthening military policies and procedures, as necessary, and ensuring that all military operations are in compliance with international humanitarian law and underpinned by the principles of distinction, proportionality and precaution; (b) Supporting the collection of data on the impact of explosive weapons on children, including by collecting and sharing such information with the United Nations; 12-45308 17
