What does urban sustainability mean?

Urban sustainability refers to the capacity of a city to maintain its essential functions and services while ensuring that resources are not depleted or exhausted over time. This concept emphasizes the importance of balancing social, economic, and environmental factors to create a livable, resilient urban environment for current and future generations.

In this context, urban sustainability involves the efficient use of resources, such as energy, water, and land, as well as the integration of environmentally friendly practices to reduce pollution and waste. It advocates for sustainable transportation systems, green spaces, and the creation of communities that support diverse populations, ensuring that the urban ecosystem remains healthy and vibrant.

The other options do not capture the essence of urban sustainability. Expanding a city without regulations, focusing solely on residential development, or ignoring environmental concerns undermines the goal of creating a sustainable urban environment. These approaches can lead to resource depletion, environmental degradation, and a decline in the quality of life for residents, which runs counter to the principles of sustainability.
