This report aims to contribute to discussions of how the international response to gender based violence (GBV) in crisis settings can be strengthened through greater alignment and coordination between humanitarian and development funding, policy and delivery mechanisms. It explores how humanitarian and development actors each approach GBV – looking at GBV policy, financing and coordination from both perspectives – as well as the areas of connectivity. The report looks in depth at the regional response to the Syria refugee crisis as an example in which the international response has sought to strengthen the linkages between humanitarian and development approaches and where addressing GBV has been a priority. Here are the key findings of the report. Neither humanitarian nor development approaches to GBV are fully equipped to address the complex challenges of GBV prevention and response in crisis settings. Both the level and quality of funding to address GBV in crisis settings is insufficient to address needs and fill gaps in response. The transition from humanitarian delivery of GBV services, dominated by UN agencies and international NGOs, to a development approach is not as simple as shifting to government-led delivery. In the context of the Syria crisis response, the main focus of efforts to work at the nexus has been for humanitarian action to shift towards a longer term, developmental approach to GBV – not for new humanitarian–development partnerships to be formed.
