Bottom-up citizen initiatives as emergent actors in flood risk management: Mapping roles, relations and limitations.

The recent shift to individualisation of flood risk calls for a stronger involvement of private actors. Bottom-up citizen initiatives (BUIs) may bring together governmental bodies with people at risk. Drawing on a screening of existing BUIs in Europe, North America, and Australia and an in-depth analysis of three study sites, this paper maps BUI activities to stages in the risk management cycle and discusses the institutional, relational and social proximity between BUIs and other stakeholders.
