The Gender Issues Programme of the OSCE Office of the Secretary General conducted a comprehensive mapping of Women’s resource centres and other integrated service providers for survivors of gender-based violence (GBV) in Central Asia, the South Caucasus, Eastern Europe and Mongolia as part of the WIN Project. The mapping aimed to collect extensive information on existing services and mechanisms for direct assistance to and protection of survivors of GBV, to assess the main gaps and the need for capacity-building and knowledge-sharing in counteracting GBV, and to identify promising approaches and good practices across the OSCE region.
