What do we call the expansion of urban areas into rural land?

The expansion of urban areas into rural land is termed "Urban Sprawl." This phenomenon typically involves the uncontrolled expansion of cities into the surrounding countryside, leading to the conversion of rural land for residential, commercial, and industrial developments. Urban sprawl often results in low-density development and can lead to various environmental and social challenges, such as increased traffic, loss of agricultural land, and changes to local ecosystems.

Urban sprawl is a significant topic in geography because it affects land use patterns, transportation, environmental sustainability, and community development. By recognizing urban sprawl, planners and policymakers can develop strategies to manage growth sustainably and preserve critical rural and natural areas.
