Understanding risk (UR) is a global community of almost 3,500 experts and practitioners in the field of disaster risk assessment. Every two years, the global facility for disaster reduction and recovery (GFDRR) convenes the UR forum - a five-day event to showcase best practices and the latest technical know-how in disaster risk assessment. The forum provides organizations with the opportunity to highlight new activities and initiatives, build new partnerships, and foster advances in the field. UR2014, the third biennial forum, was held in London, United Kingdom (UK), from June 30 to July 4, 2014. Under the theme producing actionable information, participants explored the creation of risk information for decision making. In this context, the report presents the following: changing risk and uncertainty; data; risk modelling; risk finance and insurance; psychology of risk; building resilience; and partnerships.
