Urban growth in Bangladesh demands sustainable spatial planning to manage unplanned expansion and environmental risks. This study assesses land use suitability for urban development in Barisal Metropolitan City using a GIS-based Multi-Criteria Analysis (MCA). Spatial geo-factors such as geomorphology, terrain, foundation suitability, inundation, subsidence, and earthquake hazards were analyzed using the Analytical Hierarchy Process (AHP) for weighting. The integrated GIS analysis produced a land suitability map with five classes, showing 66% of the area as low suitability (Class IV). The results highlight limited foundation strength and high earthquake risk, emphasizing the need for proper engineering solutions and geo-spatial integration in sustainable urban planning.
