ERA-MIN2 AUREOLE project : tArgeting eU cRitical mEtals (Sb, W) and predictibility of Sb-As-Hg envirOnmentaL issuEs
International audienceAntimony (Sb) is a critical metal for Europe. Indeed, Sb is widely used in a variety of industrial operations, especially in the European aircraft industry, such as production of flame retardants, plastics, paint pigments, glassware and ceramics, alloys in ammunition and battery manufacturing plants. Despite its strategic importance, the knowledge on Sb and its ore deposits remains poorly constrained. Moreover, Europe remains under the threat of an essentially Chinese supply despite a proven potential for European deposits that contain also strategic and precious co-products (W, Au). In parallel, Sb and associated metalloids (As, Hg, etc) are more and more recognised as a global threat for human health and it has been demonstrated that most of elevated concentrations of Sb on earth surface originate from natural, geogenic sources. Then, a first large-scale identification of these areas where primaries resources occur and metalloids can contaminate humans should be a priority. To achieve its objectives, the overall approach of the ERA-MIN2 AUREOLE project (2019-2022-https://aureole.brgm.fr) is based on disruptive concepts: i) development of a 3D large-scale metallogenic model integrating deep-seated processes to determine the spatial distribution of ore deposits; ii) the use of mineral prospectivity data weighted by surface data to determine the probability of environmental risk over large areas. The work package (WP) 1 is dedicated to produce the new 3D deep-seated metallogenic model for antimony mineralisations and contribute to the global 3D understanding of the Sb mineralising processes. The WP2 is designed to the understanding of processes-such as geomorphology, weathering, climate-that control the mobilisation and transport of metalloids at the earth surface. The WP3 will use results from WPs 1 & 2 to produce large-scale mineral prospectivity and a large-scale environmental risk assessment by weighting mineral prospectivity with earth surfaceproperties, such as DTM, rainfall, weathering cartographic maps, etc.The AUREOLE project will bring new scientific knowledge on Sb and Sb deposits, for a better mineral exploration targeting. The expected outcomes will be several high-impact deliverables devoted to the targeting of new Sb deposits and a new large-scale environmental assessment maps for decision-making dealing with humans health. Long term expected impacts would be an increase of EU Sb resources and EU Sb sustainable supply. Because of its implications for European critical metals, the AUREOLE project will provide new findings and results to the SCRREEN project (Solutions for Critical Raw Materials – a European Expert Network) and to the IMP@CT project (Integrated MobileModularised Plant and Containerised Tools for sustainable, selective, low-impact mining of small, high-grade or complex deposits). It will also interact with the Geo-ERA FRAME project (Forecasting and assessing Europe’s strategic raw materials needs)
Assessing local building cultures for resilience & development: A practical guide for community-based assessment
International audienceThe development of a set of tools to enhance appreciation of local practices developed by communities regarding settlements and risks is an initiative that aims to promote context-based strategies for responding efficiently and adequately to habitat improvement and vulnerability reduction needs. This guide offers a methodological and operational support for decision-making and practices towards approaches and actions deeply rooted in local contexts. It is a practical tool that provides detailed explanation on planning, preparing and undertaking field assessments of local practices related to habitat and risks. It refers to a participatory approach suitable for, and adapted to, various geographical, cultural and risk-prone areas. By supporting habitat assessment in all its different aspects, it also fosters links between programmes, providing clues and keys to define and implement coherent projects including income generating activities, livelihood, health and other related sectors. The necessary investment to be taken into account in project planning to achieve the basic step described in this booklet will result in huge savings, as logistical issues will be drastically reduced during the project implementation. It is a worthwhile investment that will lead to decisions ensuring more benefits to the affected communities, including a long-term enhancement of their resilience capacityCet ouvrage s'adresse aux responsables de projets et aux preneurs de décisions. L'auteur explique tout d'abord la démarche de projet respectueuse des cultures constructives. L'auteur présente ensuite une méthode d'évaluation des cultures constructives locales et expose l'importance de celle-ci dans un proje
