Challenges of Urban Changes - AP Human Geography

Urban sprawl. Single-family homes on large lots consume extensive land and resources.

Mixed-use development. Reduces travel distances and promotes walkable, efficient neighborhoods.

A region comprising a number of cities, towns, and other urban areas. Merged urban areas form continuous metropolitan regions with shared characteristics.

Strain on infrastructure. Roads, utilities, and services become overwhelmed by sudden population increases.

A concentration of business, shopping, and entertainment outside a traditional downtown. Suburban commercial centers that compete with traditional downtown business districts.

To regulate land use and development. Separates incompatible land uses and guides orderly urban development patterns.

Lack of employment opportunities. Economic isolation prevents residents from accessing stable, well-paying jobs.

The study of the form and structure of urban spaces. Analyzes physical layout, building patterns, and spatial organization of cities.

A city that is a primary node in the global economic network. Global cities control international finance, commerce, and cultural influence.

Improving public transportation. Accessible transit reduces car dependency and improves quality of life.

Tertiary sector transition. Economic shift from manufacturing to service-based industries and knowledge work.

Reduction of urban heat. Vegetation provides insulation and cooling through evapotranspiration processes.

Income inequality. Wealth disparity creates spatial segregation and unequal access to services.

A densely populated urban area characterized by substandard housing. Typically lacks basic services like clean water, sanitation, and formal land tenure.

Deindustrialization. Manufacturing jobs decline due to automation, globalization, and economic restructuring.

Unemployment. Job scarcity results from economic decline, automation, or industrial relocation.

The redevelopment of areas within a city, typically to address urban decay. Aims to revitalize deteriorated neighborhoods through comprehensive redevelopment projects.

To design and regulate the use of space in urban areas. Coordinates land use, transportation, and infrastructure to optimize urban functionality.

A previously developed land that may be contaminated. Former industrial sites requiring environmental cleanup before safe redevelopment.

Frequent maintenance needs. Older systems require costly repairs and upgrades to meet growing population demands.

The ranking of cities based on size and economic status. Organizes cities from global centers to smaller towns based on population and function.

Urban self-sufficiency. Cities develop local food, energy, and resource systems to reduce external dependence.

Implementing energy-efficient buildings. Reduces energy consumption and greenhouse gas emissions in urban environments.

Urban planning strategy that focuses on sustainable development. Emphasizes compact development, public transit, and environmental protection.

Traffic congestion. Results from insufficient road capacity relative to vehicle volume and population density.

Suburbanization. The movement of people from city centers to surrounding suburban areas.

A city with a population of over 10 million people. Examples include Tokyo, New York, and Mumbai with massive populations and global influence.

Increased air pollution. Vehicle emissions increase due to longer commute distances and car dependency.

The uncontrolled expansion of urban areas. Low-density development consumes large amounts of land and natural resources.
