Socio-economic sensitivity index of the French coastline (definition by municipality)
Description
Socio-economic sensitivity takes into account the use and exploitation of coastal space and resources by society (marine culture, fishing, tourism, industrial water intakes, etc.). Its assessment is based on a large number of criteria that are difficult to enter statistically (economic information from administrations), highly variable over time, difficult to combine (turnover, employment, reception capacity) and sometimes difficult to access (more or less "strategic and confidential nature of the data").
The socio-economic sensitivity index of the French coastline is constructed by adding together the types of activities present in a municipality. A weighting has been assigned to certain activities considered to be particularly vulnerable according to the criterion of Cedre’s business interruption index: x10 for water intake activities and x5 for municipalities whose foreshore is the subject of a shellfish farm.
This layer represents the socio-economic sensitivity index of the French coastline. Its cartographic representation is by commune, a scale at which data describing coastal socio-economic activities are relatively easy to obtain.
The index is divided into five classes: 0 (no activities identified), 1-3, 4-7, 8-13, greater than or equal to 14 types of activities identified (including mark-up).
