The role of the spatial scale in flood hazard and risk mapping for informing land-use planning: Insights from Aotearoa New Zealand

This paper aimed at investigating how and what type of floodhazard and risk information is used and needed to inform land-use planning decisions by focusing on the Aotearoa planningregime context. Flood related damages are escalating due to compounded climate change impacts and ongoing urban development along flood-plains. As a result, there have been increased calls to improve integration between land-use planning and flood risk managementto resolve conflicting policy objectives and minimise increasing flood risk. 

Drawing on empirical data and document anal-ysis, the findings showed that most flood mapping focused on the meso (regional) and micro (local and site/property) spatialscales and inconsistency in land-use planning decisions due to a lack of national guidance and directives on how to use flood hazard and risk information.
