Europe cities and their hinterlands are major foci of business, heritage, culture and development. Many have geological issues that inhibit economic and sustainable development. Moreover, underneath today's city streets exists a labyrinth of caves, quarries and lifelines (sewer, gas, electric and telecommunication lines). The knowledge about the location of these buried infrastructures represents crucial information for a continuous utility management, including quick response to emergencies, efficient repair working and planned extensions of existing networks. The 3D visualisation of all buried utilities as well as geoscientific information is technically feasible. However, an application integrating and visualising the subsoil components into a city model (i.e. buried networks and geoscientific information like geological models, drill-holes, hydrogeological models ...) does not yet exist. Such tools may prove to be very useful in the management of underground related issues (e.g. maintenance of networks, underground water levels, mechanical properties of soils, presence of cavities, etc), which is at the moment less intuitive due to the lack of underground information in City Models. DeepCity3D project intends to develop application-adaptive 3D visualisation tools that integrate for the first time underground data and City models (provided in standardised formats) with advanced functionalities to support decision making in Urban Planning, Construction Companies, Insurance Companies, Architects, Environmental Protection.

Rare metals (e.g. Li, Ta, Sn) are critical components for the renewable energy technologies. In Europe, a significant part of the resources issues from rare-metal granites and pegmatites (RMPG), especially those known in the Variscan belt remnants, such as the French Massif Central (FMC) and Iberian Massif. In order to achieve the green high-technology revolution, a sustainable European supply of Li and Ta needs the exploitation of the European RMPG deposits. However, the economic, environmental and societal impacts of such exploitation must be clarified. Furthermore, the geological processes involved in the genesis of such peculiar magmatic rocks and their extreme metal enrichment, e.g. the metallogenic model, remain poorly understood. This makes difficult the prediction of favourable areas for new discoveries. The TRANSFAIR project is a stimulating consortium that gathers a transdisciplinary expertise from geosciences to human sciences. It will provide a comprehensive metallogenic model for RMPG, enhancing district to deposit-scale mineral prospectivity mapping. To reach these objectives, TRANSFAIR will rely on two typical examples known in the FMC and Iberia, common learning fields for all the project activities. Based on recent results, TRANSFAIR propose to study the hypothesis of the RMPG origin from partial melting of Li-rich sedimentary source(s), combining innovative melting experiments and the characterization of natural objects following several approaches (petrology, geochemistry and geochronology). Ascent and emplacement processes, key parameters to explain the locations of the deposits, will be better constrained thanks to a coupled work of experimental petrology and numerical modelling. These results will be compared to natural case studies by a 3D understanding of the tectonic and structural contexts of ascent and emplacement of the deposits, reached by the acquisition of new geophysical and field data. Geochemistry (including stable and radiogenic isotope systematics) and geochronology will draw a better knowledge of the magmatic history of RMPG fields, from partial melting to emplacement of barren rocks and ore deposits. The integration of all these results will build predictive maps of favourable areas for RMPG. In the context of a significant increase of the needs for Li, which will lead to a strong increase of mining activities. TRANSFAIR will also draw the sociologic, economic benefits and disadvantages of new operations of RMPG in Europe and the strategy for societal engagement for renewed mining activities in Europe. Thus, TRANSFAIR will decipher the economic parameters linked to the valorisation of European RMPG by an econometric approach. Based on life cycle analysis, environmental impacts of these domestic operations will be compared to the actual global market. At last, levels of potential acceptability of mining projects in France, Portugal and Spain will be evaluated determining the concerned territories profiles, mapping stakeholders and adapting the social risk index. Simultaneously, TRANSFAIR will assess imaginaries linked to lithium, actually essential for the energy transition, making the link with the cartography of the geological potential issued from the project. As an answer to the actual needs of critical metals, TRANSFAIR will bring solutions towards better knowledge and valorisation of the European potential of RMPG, giving the keys both for a more efficient exploration, but also the bases for a better understanding between all stakeholders (citizens, public institutions and industries).

Groundwater is a strategic resource for modern economies worldwide; yet it is over-exploited at an alarming rate. New forms of governance are sought, in particular in rural areas with intensive agricultural irrigation where authorities lack the means to regulate large numbers of dispersed users. During the Fellowship, I will develop new understanding of strategies and institutional arrangements for increasing the resilience of groundwater dependent rural economies, and develop and test a methodology that support local actors to design collective solutions. Overall, the Fellowship aims to: (1) carry out a global assessment of strategies and institutions currently used worldwide; (2) develop a participatory foresight methodology to support the design of innovative strategies and institutional arrangements in two case studies; and (3) promote academic exchange and disseminate research. The Fellowship will enable me to strengthen my empirical and theoretical knowledge of the design of institutions for common-pool resource management and natural resource management, and position me as a leading scholar in the competitive research community on environmental and institutional economics. A carefully crafted series of scientific exchanges and collaborations will expand my outreach to a global level, and open opportunities for new research collaborations. The French Geological Survey (BRGM), France, is the ideal host organisation to carry out this research because of its established expertise on groundwater management with an emphasis on inter-disciplinary research of high societal relevance, and its extensive global networks. I will contribute to BRGM’s current research agenda and strengthen its collaborations in and outside Europe. My research will contribute to Europe’s knowledge base economy by providing new insights to safeguard society against water-related vulnerabilities.
