Mega-cities are large urban areas with populations exceeding 10 million residents. Their growth is significantly influenced by physical geography, which shapes how cities expand and develop over time. Understanding these geographical factors helps explain patterns of urban sprawl and infrastructure development.
Physical Geography and Urban Growth
Physical features such as rivers, mountains, and coastlines can either facilitate or hinder urban expansion. Cities often grow along waterways for transportation and trade, while mountain ranges may limit horizontal growth. Coastal areas tend to attract more development due to access to maritime routes and resources.
Factors Influencing Urban Sprawl
Urban sprawl refers to the uncontrolled expansion of urban areas into surrounding regions. Physical geography plays a key role in this process by determining available land and influencing transportation routes. Flat plains and low-lying areas typically see more extensive development, while rugged terrains restrict expansion.
Impacts of Geography on Infrastructure
The physical landscape affects the placement of infrastructure such as roads, bridges, and public transportation. For example, hilly or mountainous regions require more engineering work, increasing costs. Conversely, flat terrains allow for easier and more cost-effective infrastructure development.
- Rivers enable transportation and trade routes.
- Mountains can limit expansion and increase construction costs.
- Coastal locations attract more population and industry.
- Flat plains facilitate extensive urban development.
