What is it about?
This paper employs a fixed zonal framework (Zones A–E) to analyse LULC change from 2000 to 2024, using Landsat satellite imagery and spatial metrics, namely the Average Annual Urban Expansion Rate (AUER), Urban Expansion Intensity Index (UEII), and Urban Expansion Differentiation Index (UEDI).

Why is it important?
Our standpoints highlight the crucial importance of coordinated spatial governance, synchronized infrastructure in peripheral areas, and urban renewal in the city centre to foster equitable, resilient, and sustainable metropolitan growth in line with the Sustainable Development Goals.
Perspectives
This interesting study systematically tracked the spatial and temporal dynamics of land use and land cover change in the GAMA over 24 years, revealing a clear trajectory from monocentric consolidation to polycentric sprawl.
