<p>Imphal city, in the north-eastern state of India, has experienced substantial urbanisation over the past three decades. This study seeks to analyse and quantify the urban form of Imphal city and its surrounding regions from 1991 to 2021 by utilising Shannon entropy and landscape metrics. The study area is divided into two zones, with Zone 1 under the jurisdiction of the Imphal Municipal Corporation (IMC) and Zone 2 being the peripheral urban buffer surrounding Zone 1. Shannon entropy analysis revealed contrasting trends: Zone 1 shows declining entropy, indicating densification and consolidation of the urban core, whereas Zone 2 exhibits rising entropy, reflecting dispersed and fragmented growth at the periphery. For the overall study area, entropy increased steadily, highlighting citywide sprawl. Landscape metrics further confirm these patterns: Class Area (CA) and Percentage of Landscape (PLAND) increased across zones, indicating growing urban land cover; Number of Patches (NP) declined while Patch Density (PD) and Largest Patch Index (LPI) increased, suggesting consolidation in the core and fragmented expansion in the periphery. Edge Density (ED) trends corroborate these morphological changes. Based on the Cellular Automata Markov model, built-up areas are projected to expand further by 2031, particularly in Zone 2, while Zone 1 is expected to maintain a more organised and concentrated urban form. The study highlights a transition from a compact, monocentric city to a semi-dispersed urban morphology, with implications for infrastructure planning and sustainable urban management. The application of landscape metrics in Northeast India, especially in Manipur, remains rare; thus, these findings provide valuable empirical insights for policymakers and planners aiming to manage urban sprawl effectively.</p>
