Description du sujet

The transformation of the industrial territory of Nord Franche-Comté (NFC) requires the management of its past and its old industrial sites, often located in the heart of the city and in the flattest zones corresponding to the Allan and Doubs river alluvial plains. Their number will increase in the coming years given the changes in the production apparatus and the implications of Industry 4.0 (reduction of production areas, land releases, increasing integration of factories). The low value of these marginalized lands, in a context of a relaxed real estate market, does not spontaneously encourage their reclaiming, but rather promotes peri-urbanization, the artificialization of agricultural land, long commutes to work and the devitalization of centers. Phytomanagement (management of polluted lands by plants) is one of the alternatives to very expensive excavation/ and can contribute to the development of accessible solutions for the restructuring of sites by giving them multiple uses: housing, trade, rational economic spaces, public spaces for amenities, energy production. The general objective of the PhD-  project is to reclaim the polluted wasteland of Burgess-Norton site in Vieux-Charmont1 (Doubs, France), by the implementation of a living-lab for applied research and teaching addressing sustainability and integrating a phytomanagement approach on a polluted industrial site to bring research down into everyday life and improve the urban environmental quality. This polluted wasteland is located on the edge of the urban center, in the immediate vicinity of the Belfort-Montbéliard Greenway. We hypothesize that implementing this living lab will enable the population to acculturate to the management of the industrial heritage and to serve as a model for spreading the phytomanagement methods throughout the NFC territory and more broadly in areas undergoing industrial restructuring.

The implementation relies on three specific objectives: (1) to fully characterize spatially and quantitatively the site's pollution, mobility, and environmental and human impacts, using innovative methods that will be deployed on site to meet the technological challenges related to the management of polluted sites and soils (2) to set-up a living-lab following the National Methodology for Managing Polluted Sites and Soils2 (abbreviated NM2PS2) and its associated standard (NF X31-620) to bring together local authorities, public and private actors, companies, associations and individual actors in order to test different pollution management scenarios (3) to evaluate the replicability potential on other marginal lands of the territory. The objective, in the longer term, is to capitalize on the method to enable phytomanagement actions to be initiated on part of other marginalized lands in the NFC.

The management plan currently being performed at the site will be updated, based on the initial site diagnostic, human health risk assessments estimated with bioaccessibility, bioavailability information and cost-benefit analysis. This mission of the NF X31-620 standard is the main component of any polluted site rehabilitation project and will guarantee that pollution management measures will be taken into account. The Ph-D work will provide an innovative management plan based on both Human health and environmental risks with respect to the NM2PS2. The Ph-D project will further provide descriptors of the pollutant transfer processes along with the soil-atmosphere-groundwater-surface continuum, to ensure that the management solution is appropriate, given the urban location of the site, on the short and long terms, and to analyze targets.
