| Résumé : |
The present study aims to monitor and analyze land cover changes in the city of El Meghaier over a period of time 1984–2023 using Landsat 5, 7, and 9 satellite imagery (TM, ETM+, and OLI-TIRS). The chosen approach for this analysis is the Diachronic Analysis of Spatiotemporal Evolution (DASE), with the following objectives: (i) Detecting spatiotemporal changes attributed to urbanization and territorial policies, particularly the administrative division upgrade as the provincial capital; (ii) Understanding the complexity of urban expansion and redefining the urban boundaries of El Meghaier along the National Road 03; and (iii) Assessing the environmental impact, specifically the risk of urban expansion on the palm groves and the urbanization of low-lying areas prone to flooding. Based on the main results obtained, an ambiguous situation of conurbation is observed between the city of El Meghaier and its neighboring agglomerations (Dendouga and N'sigha), leading to a compacted territory that includes the palm groves. This dynamic and transformation are characterized by a growth rate of 251.35%, with 142.83% observed during the period 2000–2023, indicating an increase of 8.37 km² compared to the total area of 14.23 km². There is also a 108.9% increase in agricultural areas, equivalent to an additional 15.37 km², at the expense of a 45.03% decrease in bare soil.
Finally, the study concludes with interpretations and proposals for urban expansion scenarios as part of a Master's degree project in Urban Management (GTU). |
