This thesis introduces a multidisciplinary methodology structured around two scientific pillars: (i) the characterisation and classification of mining activities to analyse their variability and their positive and negative impacts on the Guianese territory; and (ii) the development of prospective mining scenarios, employing a stochastic approach aligned with the Sustainable Development Goals (SDGs). These scenarios offer a framework to explore the potential impacts of various mining trajectories and to facilitate dialogue among stakeholders. This research included the development of a digital simulation tool for mining scenarios, which was tested during a planning workshop. The workshop highlighted the tool's potential to enhance discussions on possible mining trajectories in French Guiana.
