What is urban renewal?

Urban renewal refers to the process of improving and revitalizing urban areas, often through redevelopment and intervention strategies that address physical, economic, and social conditions in those areas. It typically involves the rehabilitation of buildings, restructuring of public spaces, and enhancement of infrastructure, aiming to attract residents, businesses, and investments back to these areas.

This process is necessary for addressing issues such as urban decay, where parts of a city become neglected, leading to a decline in living conditions and a negative economic impact. Urban renewal initiatives may also involve the preservation of historical sites or cultural features while making improvements that enhance the overall quality of life for the inhabitants.

In contrast, the other options relate to negative aspects of urban environments that, while connected to the need for urban renewal, do not define what urban renewal actually is. Options discussing decay, degradation, and population density fail to capture the concept's positive nature, which focuses on improvement and revitalization.
