The SPACEMOD Project

The SPACEMOD project (SPAtially explicit MODels for exposure and impact assessment of contaminants in terrestrial ecosystems) aims to improve ecotoxicological risk assessment by explicitly integrating the spatial dimension and landscape connectivity.

In traditional risk assessments, the environment is often treated in a simplified or homogeneous manner. SPACEMOD proposes a spatialized modeling approach that accounts for:

  • Land use and cover (specifically via OCS-GE data) to identify pressure sources.
  • The structure of the trophic network and landscape connectivity.
  • The transfer of contaminants from source ares to terrestrial organisms.

The goal is to provide tools to predict organism exposure and understand how landscape structure influences ecosystem vulnerability.

The R Package: spacemodR

This application serves as the graphical interface for the spacemodR R package, developed to facilitate the manipulation of complex geospatial data within an ecotoxicological framework.

Key features of the package include:

  • Automated retrieval of geographic data (FlatGeobuf API).
  • Processing of Land Use/Land Cover data (OCS-GE) and habitat definition.
  • Construction of spatial graphs to model trophic networks and organism dispersion.
  • Integration with exposure models for landscape-scale risk calculation.

The source code is available as open-source software on GitHub: Qonfluens/spacemodR
