In Morocco, solid household waste is often disposed of in open air in unsuitable sites, causing adverse effects on humans and the environment. In the province of Settat, there are eight uncontrolled landfills. The present study aimed to determine the most suitable sites from an environmental and economic point of view to ensure good management on a regional scale. The investigation involved a combination of a multi-criteria method (the AHP analytical hierarchy process) and a GIS geographic information system (ArcGIS) with ten criteria: distance from the ground water, water surfaces, drilling, settlements, forests, roads, highway, land use, slope, and elevation. The suitability map showed that about 18.5% of the study area is suitable for installing a sanitary landfill.

In Morocco, the population growth and changes in consumption and production patterns are increasing the amount of generated waste, particularly household solid waste. It is estimated at 6.9 million tons per year, of which 5.5 million tons in urban areas, with a ratio of 0.76 kg/inhabitant/day (Ministry of the Interior, national portal for local authorities, National Household Waste Program). In the absence of controlled landfills, this waste negatively affects living spaces and generates health and environmental problems. The province of Settat, which is affected by this scourge, inefficiently manages this household waste as in other regions, thus requiring improvement with the involvement of the actors concerned. This work involves the creation of a cartographic database of household waste in the province of Settat using a Geographic Information System (GIS). The analysis of the maps made, the observation of photos of existing landfills, and a diagnosis of the landfills in the Settat province have shown a direct negative impact on the different vital axes.

The province of Settat plays a key role in supplying the building materials that meet the needs of the province as well as the provincial construction and public work sectors. Indeed, the province is full of natural potential in raw materials and counts more than 109 quarries. This study aimed to build a quarrying database in the province of Settat to both characterize the materials mined and map the quarries through the Geographic Information System (GIS). This mapping allowed conducting the geographical distribution analysis of quarries by territorial unit and type of materials. The results revealed a predominance of carbonate quarries, especially in the Ben Ahmed circle. This distribution can be explained by natural, economic, and logistical factors characterizing the study area.
