IDEFESE Models and data

IDEFESE leverages a range of tools and spatial datasets for ES in Ile-de-France. With the goal to develop reproducible analyses, we favor open source tools and data.

Models:

  • The main software tool is the open source InVEST suite, developed by the Natural Capital Project: InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) ;
  • Urban cooling service by vegetation is modeled through the new Urban InVEST tool calibrated on outputs from  the Town Energy Balance developed by Meteo France;
  • Own developed statistical and geographical models (R, GIS, and Python);
  • SLEUTH, a cellular automaton model to simulate urban growth or sprawl and SLUM (Simple Land Use Change Model) developed for the project.

Data

IDEFESE uses for instance:

  • Land use and land cover datasets : the MOS land use/ land cover maps (MOS), urban morphological units (IMU), Local Climate Zones, road networks, developed by IAU-IdF;
  • Biophysical datasets: Digital elevation models (BD ALTI, IGN), Watersheds (Agence de l’eau Seine-normandie and IAU-IDF)
  • Socio-demographic data are obtained from INSEE (IRIS level) ;
  • Academic litterature ;
  • Survey realized in Ile-de-France for the outdoor recreation service;
  • Semi-structured interviews of different stakeholders of urban planning.

Stakeholders involved in IDEFESE

We involve roughly 50 urban planning stakeholders representing more than 25 institutions. Stakeholders were chosen according to their influence and their expertise in land use planning and management in the region. Stakeholder selection was also driven by the aim of representing a diversity of perspectives regarding the question of nature in cities.

Stakeholders were involved 1) in the choice of ES to analyse with high priority 2) in the feedback on indicators produced and ways to model ES, 3) to analyse the principal results produced and, 4) to assess how ES maps can become a real action levers in urban planning documents. Stakeholders were consulted following different modalities. First, we conducted two focus groups, one in the beginning of the study (September 24th 2018) to select the services and indicators for the modelling, and one at the end of the process (May 28th 2019) to present and discuss the results. The first focus group involved 18 persons and the second 16. During this period, 26 face-to-face interviews, over an hour, were conducted to investigate deeper the issue of how ES can be used in urban planning document (see the first IDEFESE report : Tardieu et al. 2019 -in french).
