Abstract
The suggested approach is located on three workshop sites which are representative of different regional contexts: mining area (workshop site “Metaleurop”), brownfield (“Union”), organic market gardening (“Jardin de Cocagne” in Villeneuve d’Ascq). The first two are part of the SAFIR network which is supported by the ADEME and enjoy national recognition. The interest of those three sites lies in the fact that they present situations that are typical of use changes, for which some data has been or is being collected. On top of an analysis of habitat landscapes and soils (physicochemical parameters and contamination level), an in-depth study of biodiversity will be carried out, both following a classical taxonomic approach on soil invertebrates and a soil DNA sequencing technology (metabarcoding). The functional aspects will be based on the characterisation and follow-up of microbial activity (biomass, functional diversity) and on the study of organic matter degradation. The aim will be to understand how anthropogenic development and restoration modalities could encourage the return of functional biodiversity according to the landscape context.
