Analysis of Copernicus data relating to the 2017 fires on Vesuvius

Analysis of Copernicus data relating to the 2017 fires on Vesuvius

In July a arson fire of vast proportions affected the area of Vesuvius National Park generating extensive damage. With this article, in which I reworked the Copernicus data, I tried to quantify the extent of the types of soil destroyed also making use of the Corine Land Cover data and the DTM LiDAR of the Città Naples Metro.

During one of my bike training sessions in those days, I approached Monte Somma and the scenery was what you see in the following video.

The Park burned for almost a week on both the Monte Somma and Vesuvius sides.

The following image shows land use before the fires, the data is an extrapolation of the CLC2000 present in the vector package downloadable from here.

The total extent of the vectors that make up the different types of land use is equal to approximately 4,400 ha, appears to be more small compared to Copernicus data only because it is I preferred to focus on the areas of greatest damage.

  CLC2000 soil description Type extension

  Areas with evolving woodland and shrub vegetation 932.96 21
  Areas with sparse vegetation 89.8 2
  Areas mainly occupied by agricultural crops with the presence of important natural spaces 255.31 6
  Coniferous forests 677.04 15
  Broadleaf forests 811.5 18
  Mixed coniferous and deciduous forests 732.78 16
  Orchards and minor fruits 59.6 1
  Bare rocks, cliffs, cliffs, outcrops 257.17 6
  Complex cultivation and particle systems 653,18 15
  Total extension 4,469.34  

 

The largest extensions concern the wooded areas and unfortunately they are the ones that have had the greatest damage. The following image represents the post-fire scenario.

  Total extent 4,469.34 1,045.17 303.22 184.83 2,936.12

Analyzing the data in the previous table is It's easy to assess which is gone up in smoke:

  • 70% of the coniferous forests, going from 677.04 ha to 203.44 ha;
  • 65% of the evolving woodland and shrubby vegetation areas, going from 932.96 ha to 323.90 ha;
  • 38% of the areas with orchards and minor fruit, going from 59.6 ha to 36.72 ha.

This is just to mention the first three types of soles for damage suffered. The totally destroyed areas, falling within the Vesuvius National Park, cover an area of ​​1,045.17 ha; For comparison, a regulation 11-a-side football pitch is about 1 ha.

Below are some comparison diagrams.

What should we expect with the next rains, typically heavy especially between September and October? We'll see, unfortunately.

In the meantime, I am heartened by the fact that nature is slowly regaining its spaces; to restore the woods however it will take years if not centuries!
