A/71/206 priority areas to which the African Union and its Member States commit themselves for the next 25 years. 5 66. As noted in the African Report on Violence against Children, significant efforts are needed to address violence in the region, including through gendersensitive data collection and analysis to track prevalence and trends. These actions can build upon significant achievements made across the region to prevent and address this phenomenon. 67. Indeed, a number of countries are strengthening their national child protection systems and have undertaken comprehensive surveys on violence against children to document the magnitude, nature and impact of physical, sexual and emotional violence in childhood. Information from the surveys has supported government advocacy, policy, planning and budgeting, as well as the enactment of legislation, including with a view to combating child marriage. 68. Seven countries in Africa have completed comprehensive surveys on violence against children, namely Kenya, Malawi, Nigeria, Swaziland, the United Republic of Tanzania, Zambia and Zimbabwe. These are to be followed by Botswana, Côte d’Ivoire, Mozambique, Rwanda and Uganda. 69. In February 2016, the Special Representative supported the launch of the results of the Nigeria survey, conducted by the Government in cooperation with UNICEF and the Together for Girls partnership. Nigeria was the first country in West Africa to conduct such a large-scale national survey. In response to its findings, the Year of Action to End Violence against Children was launched, along with a call to action for federal and state ministries and agencies, non -governmental organizations, faith-based organizations, the media, communities, parents and children to join together to prevent and respond to violence against children. 70. In the United Republic of Tanzania, a survey conducted in 2011 had informed the development of a national action plan to end violence against children, which ended in June 2016. Building upon the lessons from the plan’s implementation process, the Government issued a new plan for the period 2016 -2021 addressing violence against women and children and promoting a unified national protection system to be implemented in line with the 2030 Age nda, particularly targets 5.2 and 16.2. 71. The First African Girls’ Summit on Ending Child Marriage in Africa was held in Lusaka in November 2015. Hosted by the African Union and the Government of Zambia, the Summit gathered Heads of State and Government , ministers responsible for gender and children, United Nations entities, development partners, civil society organizations and religious and traditional leaders, as well as young people who have experienced child marriage. The participants took stock of t he progress made to end child marriage across the continent, shared evidence and good practices and renewed their commitment to bringing an end to this and other harmful practices in Africa. 72. The Special Representative will further enhance her collabor ation with the African Union, the Special Rapporteur of the African Union on Child Marriage and other partners with a view to the swift implementation of the plan of action for the implementation of the African Common Position on the African Union Campaign to __________________ 5 14/23 See www.acerwc.org/ourevents/africas-agenda-for-children-2040. 16-12906
