Abstract
Effective land resource management and sustainable development, particularly in urban green spaces, rely on strategicland planning and mapping techniques such as Remote Sensing. This study utilises object-based classification techniques,employing Google Earth Engine and Quantum Geographic Information Systems (QGIS), to examine Lusaka City's greenspace encroachment. Findings reveal a 59% increase in built-up areas towards the north-east direction and a 2% declinein green spaces towards the south-east part of Lusaka. The implications are significant, highlighting the urgent need forintervention to preserve the city's environmental balance. Immediate action is essential, requiring rigorous regulations,community engagement, and stakeholder collaboration. Furthermore, the study underscores the critical role of remotesensing in monitoring urban green spaces and identifying sustainability threats, emphasising the importance of prioritisingthe protection and improvement of green spaces through comprehensive land use planning and land use land covermapping through the use of object-based classification techniques.
