Urban land is a fundamental concept within urban studies, geography, planning, and related disciplines, referring to the spatial and material substrate of cities and metropolitan areas. As a research concept, it investigates the physical space within urban boundaries, analyzing its characteristics, patterns of use, transformation, and the complex interplay between the built environment, human activities, ecological systems, and socio-economic processes. Its significance lies in understanding the dynamics of urbanization, land-use change, sustainability challenges, spatial inequalities, and the development of effective urban policies.
