    The current issue addresses a diverse range of topics relevant to urban infrastructure in both global and Ethiopian contexts. It includes the investigation of machine learning models for foodborne disease classification, shedding light on health and safety within urban environments. Business failure and the organizational capacity of contractors in Ethiopia are explored, highlighting the critical role of institutional strength in infrastructure development. A GIS-based analysis of land use and land cover change dynamics in the Boricha Catchment of the Central Main Rift Valley Lakes Basin of Ethiopia provides insights into environmental management and urban expansion. The effects of green supply chain practices on the environmental sustainability of Ethiopian small and medium-scale garment manufacturers are examined, connecting industrial growth with ecological responsibility. Further, the issue discusses Building Information Modeling (BIM) education and training in Ethiopia, emphasizing its significance in modern construction practices. "The Urban Paradox: Navigating Social Challenges and Building Resilience in the Heart of Cities" offers a deep dive into the socio-economic dynamics in selected cities of the Southern Corridors of Ethiopia. Conservation and restoration practices for historical buildings in Arada Sub-City, Addis Ababa, are investigated, demonstrating the importance of cultural heritage in urban planning. The stress analysis and optimization of critical components in plunger pumps illustrate advancements in mechanical systems vital to urban services. Finally, the issue presents perceptions of households towards urban waste management challenges, drawing evidence from the Southern Ethiopia Urban Corridor and underscoring the role of public engagement in sustainable urban living.
