In today’s world, sustainability is crucial, particularly in managing natural resources for sustainable development. Often, environmental impacts of new activities are overlooked, worsening the effects on already vulnerable environments. Our study uses two multi-criteria decision-making tools, MACBETH and AHP, integrated with GIS technology, to evaluate quarry sites in Settat Province, Morocco. This methodology classifies sites by suitability, based on criteria aligned with sustainable development goals. We found a high consistency between MACBETH and AHP, with less than 4% divergence in criteria weighting, confirming the robustness of our integrated approach in making location-based decisions for quarries. The resulting maps clearly delineate zones from unsuitable to highly suitable for quarrying. Beyond assessing current quarrying practices, our findings offer strategic insights for future site planning and establishment, showcasing adaptability and potential for replication. This research provides a practical model for improving material extraction practices, aligning with sustainable development needs, and serving as a valuable tool for policymakers and industry stakeholders.

For decades, the positioning of the sites of the extraction of materials was based, on the economic profit, (existence and abundance of the deposit, proximity of the basins of consumption) and the social aspect (number of jobs created), the environmental dimension was little or not taken into account. However, because of the negative impacts of this industry, more and more felt by the population, and in addition to the awareness of the protection of the environment, decision-makers have been forced to rethink their decision-making policies. Thus, it has become necessary to adopt sustainable management of this sector, taking into account environmental, social and economic issues. In this context, the presented work proposed the mathematical method of decision-making MACBETH (Measuring Attractiveness by a Categorical Based Evaluation Technique). This approach is based on economic, social, and environmental criteria, which have been chosen concerning sustainable development issues. The selection of options reflects the geographical distribution as well as the typology of materials at the level of the study area. Then, the attractiveness of the options on each weighted criterion was evaluated following the preferences presented by the decision-makers and finally their aggregation by the MACBETH tool. The implementation of this tool made it possible to evaluate the exploitation of existing quarries at the study area level and to predict the optimization of future locations.
