Abstract
Urban expansion in Ethiopia is a significant phenomenon driven by rapid population growth, rural-urban migration, and socio-economic transformations. This study investigates the spatial and temporal dynamics of urban expansion in Gullele Sub-city, Addis Ababa, using Geographic Information System (GIS) and Remote Sensing technologies from 1993 to 2023. The study utilizes multi-temporal satellite imagery and spatial analysis to map land-use/land-cover changes, identify urban sprawl patterns, and measure the accuracy of classifications over different time periods. Socio-economic data and demographic characteristics are integrated to explore the relationships between urbanization and its impacts on agriculture, natural resources, and infrastructure. The findings highlight significant land conversion from agricultural to urban uses, driven by population pressures and policy inefficiencies. The study showed that the proportion of built-up area increased from 47.32 % in 1993 to 53.37% in 2023 (growing by 6.05%); agricultural land areas experienced a decrease from 4.97% in 1993 to 2.28% (decreased by 2.69%); Forest areas showed increase from 29.59% in 1993 to 31.43% in 2023(expanded by 1.84%) and finally Shrub land shows decrease from 19.12 to 12.92% in 2023 (shrinking by 5.2%). This has led to challenges, including displacement, environmental degradation, and inadequate urban infrastructure. The research concludes the existence of substantial urban expansion that calls for evidence-based urban planning, improved land-use regulations, and the application of geospatial technologies for effective resource management. This work provides critical insights for policymakers, urban planners, and stakeholders in addressing the challenges of urban expansion and promoting sustainable development in rapidly growing urban areas like Gullele Sub-city.
