The Monitoring and Reporting Mechanism (MRM) has offered a unique opportunity for country teams to strategically engage with parties to a confl ict to address grave violations against children. The information collected through the MRM has served not only to highlight the impact of confl ict on children, but also as a basis for the 20 Action Plans negotiated and signed by parties to a confl ict in at least 13 situations thus far, leading to the release of thousands of children from armed forces and armed groups. Indeed, a key strength of the MRM is its capacity to assert political pressure that is rooted in the listing of parties to the confl ict in the annexes of the United Nations Secretary-General’s Annual Report to the Security Council on Children and Armed Confl ict. The MRM has also provided a strong framework for advocacy with wider audiences, such as Member States at country level and other actors in a position to infl uence change. MRM data have also served to inform and trigger preventive action and programmatic response for affected children, this being a main value of the mechanism by attempting to link monitoring to response. The MRM has hence proved to be far more than a data collection tool, or an effort to ‘name and shame’ parties to a confl ict. Rather, it is a mechanism that calls for immediate attention to the situation of children affected by armed confl ict, and equips actors at the country level with tools that can be used to address grave violations.
