Ecological sensibility

 

This index provides a measure of the intrinsic predisposition of  the landscape physiographic unit to the risk of ecological and environmental degradation, in analogy to what defined at the scale 1:50,000 for biotopes.
 

It is based on the analysis of the ecological systems structure related to the specific physiographic unit. In particular, after the experimentation of several indicators, it was decided to use only the Jaeger fragmentation index (Landscape Division Index) calculated on natural systems, which by itself is a good overall indicator of environmental sensibility related to a physiographic unit.
 
To calculate the environmental sensibility we follow two phases:

- the bundling and merging of ecological systems based on their naturalness value, using the map of ecological systems;
- the index of fragmentation of ecological systems with high naturalness is then calculated.
