Communicating the risk of erosion: The effects of map-based communication on risk perception and affect

This study aims to investigate how different cartographic representations of coastal erosion influence lay citizens' risk perception and emotional responses, and how variations in map design affect the observation and interpretation of the conveyed message.

In conclusion, the authors suggest the use of correlation maps representing the evolution of the coastline over time to represent the risk of coastal erosion when communicating to the non-expert public. Moreover, this map includes elements already recommended in the study by Meyer et al. (2012) for better understanding by the general public: representations of defences, use of text, non-expert vocabulary. However, the scale needs to be carefully considered to avoid minimising the risk.
