A/HRC/23/17 E/CN.6/2013/8 investigation developed by the grantee. In response to the lack of, or inadequate, data on murders of women across the country, Católicas por el Derecho a Decidir has also identified eight minimum variables that should be reported when registering cases of femicide. These variables have been adopted by the Attorney General of Mexico City and will likely be replicated in other states and at the federal level. IV. Generating knowledge and developing capacities 28. As the leading global fundraising mechanism dedicated to the elimination of violence against women and girls, the Trust Fund is an international hub of knowledge generation and dissemination. The knowledge generated through programmes supported by the Trust Fund provides a blueprint for what works to eliminate violence against women, but also highlights gaps in programming and funding that must be addressed. 29. What is increasingly becoming evident is that ending violence against women requires a comprehensive approach that includes prevention, assistance to survivors, a robust legal and policy framework and law enforcement capability. Without exception, programmes supported by the Trust Fund identify deep-seated stigma and discrimination against women and girls at the individual, community and institutional levels as the most important factors contributing to the vulnerability of women and girls. Analysis and evaluations of programmes supported by the Trust Fund are revealing that when it comes to the elimination of violence against women, strategies for change are the responsibility of all. The elimination of violence against women requires systematic and continuous reflection by individuals, communities and national and international institutions on beliefs, behaviours and practices and how these beliefs and practices may affect policies, programmes and actions. 30. The collective experiences of the programmes supported by the Trust Fund reveal that there are four common approaches that are critical to delineating a comprehensive response to ending violence against women. The analysis shows that 90 per cent of the grantees have put in place initiatives to strengthen the response to violence against women, to prevent the occurrence of violence and, where violence is perpetrated, to support survivors in the most effective way. Grantees of the Trust Fund have identified the need for multidimensional responses to ending violence against women, in the preventive, remedial and rehabilitation stages of the spectrum and have implemented this approach through one-stop centres, common protocols and the building of individual and institutional capacities to foster a unified response to violence against women. More than one third of the grantees have identified eradicating the root causes of violence against women as a core strategy and have used numerous interventions to change the beliefs, traditions, perceptions and behaviour of people. Among these interventions, those involving working with men and boys and with community, tribal and religious leaders are the most relevant, along with those promoting community-based research and awarenessraising through public information campaigns. A third approach is the production and enrichment of knowledge to support advocacy for social transformation, policy and action, with 41 per cent of the portfolio of active grants using this strategy mainly through (a) conducting surveys and baseline research; (b) mapping resources and services; (c) piloting programmes and drawing on knowledge from individual 10 12-64357
