Industrial Risk Clusters in the Gironde Region

Project Title

Industrial and Environmental Risk Clusters in the Gironde Region

This project investigates how industrial risks are distributed across the Gironde region, focusing on clusters of ICPE sites, pollutant-emitting industries, pipelines, and former industrial activity.

Research Goals

The goal of the research project is to:

• Identify and visualise clusters of industrial and environmental risks
  
• Highlight communes with the highest concentration of hazardous sites
  
• Explore spatial relationships between different risk sources
  
• Create a risk hotspot map for the Gironde region

Research Questions

The project addresses four main research questions:

1. Spatial Distribution
   • How are industrial and environmental risk facilities (ICPE, IREP, pipelines) distributed across Gironde?
2. Clustering
   • Do pollutant-emitting installations cluster near ICPE sites or hazardous-material pipelines?
3. Historical Overlap
   • Is there a spatial overlap between current pollutant-emitting sites and former industrial sites?
4. Risk Density and Discharges
   • Do communes with the highest density of ICPE and IREP also show the highest environmental discharges?

Research Data

This project uses several publicly available open-data sources related to industrial risks and environmental infrastructures in the Bordeaux–Gironde region.
The main datasets are listed below:

1. Former Industrial Sites (CASIAS) – Bordeaux Métropole

Dataset containing geolocated information on former industrial or potentially contaminated sites.

2. Pipelines and Fluid Transport Networks

Dataset describing underground and above-ground pipelines transporting various fluids.

3. Industrial Facilities Reporting Pollutant Emissions (ICPE + IREP)

National datasets listing industrial installations that emit pollutants into air, water, or soil.

4. Geographic Base Maps (GADM – France Administrative Boundaries)

Used for loading and plotting the Gironde department.

Datasets Used

• Former industrial sites and service activities
  • Historical dataset of discontinued industrial activity
• Pipelines (hazardous materials)
  • Linear network showing transport of hazardous substances
• Pollutant-emitting facilities (IREP)
  • Industries reporting emissions to air/water
• ICPE (Installations Classées)
  • Regulated industrial facilities (active or ceasing activity)

Planned Data Operations

• Mapping the spatial distribution of all risk datasets
  
• Creating risk density maps of pollutant-emitting facilities
  
• Performing buffer analysis around hazardous-material pipelines
  
• Comparing current vs former industrial sites to detect overlap

Data Visualisation Plan

The visualisation section of the project will include:

• Base map of all industrial risks
  
• Heatmap (density map) of pollutant-emitting industries
  
• Pipeline buffer map showing sites within 1 km
  
• Overlap map comparing current vs former industrial activity

Each visualisation supports a specific research question.
