The M'Zab Valley, located in the Saharan region of Ghardaïa in Algeria, has been a UNESCO World Heritage Site since 1982. Renowned for its unique architecture, harmonious social organization, and remarkable adaptation to the arid environment, this region now faces major challenges such as uncontrolled urbanization, environmental degradation, and socio-economic pressures.This research explores the use of Geographic Information Systems (GIS) to preserve this exceptional heritage by actively involving local communities in sustainable and participatory management. The study focuses on analyzing spatial dynamics using satellite imagery (Landsat 1984–2024 and Sentinel-2) to identify and understand the threats to the region, particularly the risk of sand encroachment. Through mapping, GIS makes it possible to locate vulnerable cultural and natural sites and to produce environmental vulnerability maps.Based on these analyses, solutions and recommendations will be proposed to mitigate the negative impacts of urban expansion. These measures aim to protect fragile heritage sites while promoting balanced territorial development that respects the environment and the socio-cultural dynamics specific to the M'Zab Valley.
