This paper aims to lay the foundations for a methodological approach, albeit still in its early stages, to the archaeological and geographical study of the ancient routes that ran through the Souss plain and its Atlas foothills between the early medieval period and the 16th century. The approach first calls for the definition of various elements of analysis, at different scales. At the micro level, the survey involves a survey of the types of fundamental material units that make up the paths and tracks, using archaeology. At the meso level, the study focuses on the layout of communication routes, and proposes a number of hypotheses on the interaction between these routes and agricultural practices on the one hand, and water use on the other. The final part of the contribution, focusing on an analysis on a macroscopic, i.e. regional, scale, provides a preliminary assessment of what we know about the roads in the Sous region, giving a diachronic overview of their evolution.
