21. Stresses the importance of, and critical need for, concerted efforts to eliminate impunity for violence against women and girls in situations of armed conflict, including by prosecuting gender-related crimes and crimes of sexual violence, by providing protective measures, counselling and other appropriate assistance to victims and witnesses, by integrating a gender perspective into all efforts to eliminate impunity, including in international, internationally supported and domestic courts and other tribunals, commissions of inquiry and commissions for achieving truth and reconciliation, and invites the Special Rapporteur to report, as appropriate, on these mechanisms; 22. Also urges States to mainstream a gender perspective into all policies and programmes, including national immigration and asylum policies, regulations and practices, as appropriate, in order to promote and protect the rights of all women and girls, including the consideration of steps to recognize gender-related persecution and violence when assessing grounds for granting refugee status and asylum; 23. Further urges States and the United Nations system to give attention to, and encourages greater international cooperation in systematic research and the collection, analysis and dissemination of data, including data disaggregated by sex, age and other relevant information, on the extent, nature and consequences of violence against women and girls, and on the impact and effectiveness of policies and programmes for combating this violence; 24. Calls upon all relevant United Nations bodies, States, the Special Rapporteur, as well as relevant non-governmental organizations, to cooperate closely in the preparation of the Secretary-General’s in-depth study on all forms of violence against women; 25. Encourages the Special Rapporteur to respond effectively to reliable information that comes before her and requests all Governments to cooperate with and assist the Special Rapporteur in the performance of her mandated tasks and duties, to supply all information requested, including with regard to implementation of her recommendations, and to respond to the Special Rapporteur’s visits and communications; 26. Bears in mind the need to develop, with full participation of all Member States, an international consensus on indicators and ways to measure violence against women, calls on the Special Rapporteur to recommend proposals for indicators on violence against women and on measures taken to eliminate violence against women, for the use by, inter alia, Member States; 27. Invites the Special Rapporteur, with a view to promoting greater efficiency and effectiveness, as well as enhancing her access to the information necessary to fulfil her duties, page 9
