While a large range of potential adaptation options exists, in the more severe cases it will be necessary to consider retreating from flood-prone areas and relocating settlements and critical infrastructure.The Hertie School of Governance and Ecologic have recently completed a study project, the outcome of which is a report on policy options to achieve and encourage resettlement in flood-prone areas. The report is now available for download.
