1/5 Other models - Unreliable
CLIMATE EXPOSURE ANALYSIS MODEL IN FRANCE
DROUGHTS HAZARD
The analysis of climate exposure to the hazard “Droughts” in France is currently based on 3 territorial indicators:
-
The level of risk of shrinkage and swelling of clays (RGA)
-
Municipalities covered by a droughts risk prevention plan
-
The number of declaration of natural disasters for droughts
Other indicators will be added later. The combination of all the indicators will make it possible to assess the climatic exposure of an area, compared to the climatic exposure in the rest of France.
Under construction
Risk of shrinkage and swelling of clays
Definition of the indicator: This indicator makes it possible to show the zones subject to a risk of shrinkage and swelling of the clays by indicating the level of risk (high, medium, low, zero, unknown) to which a zone is subjected.
Indicator ID: RGA
Mesh: ~250 m (depending on risk levels)
Source: Georisques
Data processing: The data can be downloaded directly in cartographic format from Georisques. A verification of geometries and definition of symbology according to the level of risk has been done.
Scope: Metropolitan France
Municipalities covered by a droughts risk prevention plan
Definition of the indicator: This indicator indicates whether the municipality is covered by a Natural Risk Prevention Plan for a drought-type hazard (risk of differential subsidence).
Indicator identifier: FR_pprs
Mesh: communal
Source: Georisques - BD Gaspar
Data processing: The Gaspar database lists all the Natural Risk Prevention Plans which are prescribed, under review or adopted throughout France, at the municipal level. A selection of the municipalities on the metropolitan territory was made, and a second selection was made to keep only the municipalities concerned by a Risk Prevention Plan for a drought-type hazard.
Scope: Metropolitan France
Number of declaration of natural disasters for droughts by municipality
Definition of the indicator: This indicator indicates the number of CatNat decrees (declaration of natural disaster) that have been published in each municipality in metropolitan France, for a drought-type hazard (risk of differential subsidence). The Gaspar database lists all CatNat decrees for compensation purposes in the face of natural disasters. Indeed, the state of natural disaster recorded by decree may give the right to be covered against the effects of these disasters on the property covered by the insurance contracts. The count of these decrees therefore makes it possible to report on the historical loss experience of the municipality regarding droughts.
Indicator ID: FR_CatNat_S
Mesh: communal
Source: Georisques - BD Gaspar
Data processing: The Gaspar database lists all of the CatNat decrees (declaration of natural disasters) on French territory, at the level of the municipality. A selection of the municipalities on the metropolitan territory was made, and a second selection was made to keep only the municipalities concerned by a Risk Prevention Plan for a drought-type hazard. Finally, a count of the occurrence of each municipality was made.

DROUGHTS HAZARD
In order to calculate the vulnerability of buildings to the hazard “Droughts”, a certain amount of information is necessary. In order to collect them, a form is available to complete the characteristics of your project.
If no information is transmitted, the vulnerability defaults to 100%, with zero reliability.
Under construction
The vulnerability reliability index is calculated from the number of questions answered compared to the total number of questions. It varies from 0 to 5.
