Abstract: Rapid land use and land cover (LULC) change, driven primarily by urbanization, presents significant challenges to ecological conservation and sustainable development. Understanding and predicting these transformations is crucial for effective land management and policy formulation. This study investigates the dynamic LULC changes in Okara District, Pakistan, from 1994 to 2024 and projects future patterns for 2034 and 2044 using the Cellular Automata Markov (CA-Markov) model. Okara District is experiencing rapid urbanization, impacting its natural resources and environment. This research employs a hybrid CA-Markov model integrated with GIS techniques to analyze historical LULC changes and predict future scenarios. Landsat-5, 8, and 9 were used for the decision tree classifier (achieving high accuracy above 95 %). Vegetation decreased from 92.681 % (3998 km2) to 88.160 % (3803 km2), while built-up area increased from 1.697 % (73 km2) to 8.437 % (364). Barren land also reduced from 4.999 % (215) to 2.719 % (117), with water bodies remaining relatively constant. The CA-Markov model, which has been validated with a kappa coefficient of 0.91, predicts the continuation of these trends. By 2033, vegetation is projected to decline to 85.852 % (3704 km2), with the built-up area expanding to 11.119 % (480 km2). These trends are predicted to continue until 2044, with vegetation decreasing to 81.799 % (3529 km2) and built-up area reaching 14.886 % (642 km2). Barren land is projected to decline to 2.185 % (94 km2) by 2033 and 1.735 % (75 km2) by 2044, while water bodies may slightly increase. These findings highlight the district's urgent need for sustainable land management practices. This research contributes to a better understanding of LULC dynamics in rapidly changing regions, supporting informed decision-making for sustainable development.
