In the coming decades, cities in developing regions, especially in Asia and Africa, are expected to see a massive influx of people. Every day, around 170,000 individuals will either move to or be born in these urban areas. Cities offer numerous benefits, such as a wide range of job opportunities, vibrant cultural scenes, community engagement, and efficient resource use. Their compact design allows for the effective management of water, power, transportation, building materials, and land.
Despite the advantages, cities aren’t always the ideal compact environments we imagine. They often have dense urban centers surrounded by sprawling residential, commercial, and industrial zones. While suburbs are often thought of as charming areas with green spaces and beautiful homes, they can vary greatly. People living in suburban areas usually consume more energy, water, and resources, and produce more pollution compared to those in denser urban neighborhoods. They often travel longer distances for work and school, own more vehicles, and maintain larger homes and yards, which can reduce the efficiency of urban centers.
As a result, cities with sprawling suburbs and low overall densities are less efficient than those that are more densely packed. Unfortunately, urban areas around the world are expanding in size at twice the rate of their population growth, leading to increased land and resource consumption per person.
To tackle this issue, we could aim to reduce resource-intensive suburban sprawl. However, cities often grow in ways that naturally encourage it. Factors like wide highways and affordable fuel make car use and commuting more appealing, while building height restrictions and separate zoning for residential and commercial areas push development outward.
Policies are crucial in shaping the future of our cities. By investing in mass transit and increasing fuel prices, we can encourage people to rely less on cars and live closer together. Mixed zoning laws can allow people to work and enjoy leisure activities near their homes, promoting a more efficient use of resources. When people live in denser environments, they tend to use resources more efficiently.
In urban planning, as in many aspects of life, we face a choice: embrace sprawling growth or opt for vertical development. By making thoughtful decisions and implementing effective policies, we can build cities that are not only more efficient but also more enjoyable places to live.
Engage in a debate with your classmates on the pros and cons of urban sprawl versus vertical development. Consider factors such as resource efficiency, quality of life, and environmental impact. Prepare arguments for both sides and be ready to defend your position.
Create a model of a sustainable city using materials like cardboard, paper, and recycled items. Focus on incorporating elements such as mixed-use zoning, efficient public transportation, and green spaces. Present your model to the class, explaining how it addresses the challenges of urban sprawl.
Work in groups to draft a policy proposal aimed at reducing suburban sprawl in a fictional city. Consider measures like increasing fuel taxes, investing in public transit, and revising zoning laws. Present your proposal to the class and discuss its potential impact on urban development.
Conduct a research project analyzing the resource consumption patterns of urban versus suburban areas. Use data to compare energy use, water consumption, and pollution levels. Present your findings in a report, highlighting the implications for urban planning.
Visit a nearby city or urban area to observe and analyze its layout, transportation systems, and zoning practices. Take notes on how these elements contribute to or mitigate urban sprawl. After the trip, write a reflection on how the experience has influenced your understanding of urban planning.
Every day for the next 35 years, an average of 170,000 people will move to or be born in cities in the developing world, primarily in fast-growing areas in Asia and Africa. There are many advantages to urban living: cities offer numerous job opportunities, vibrant art scenes, community engagement, and efficient use of resources. Their compact nature allows for the efficient use of water, power, transportation, building materials, and land.
However, cities are not always the idealized compact environments we envision. They often consist of urban cores surrounded by sprawling residential, commercial, and industrial zones. While many imagine suburbs as picturesque areas with green spaces and charming homes, suburbia varies widely. Residents in suburban areas typically consume more energy, water, and resources, and generate more pollution than those in denser urban neighborhoods. They tend to travel further for work and school, own more vehicles, and maintain larger homes and yards, which undermines the efficiency of the urban centers.
As a result, cities surrounded by sprawling suburbs with low overall densities are less efficient than those that are more densely packed. Unfortunately, urban areas worldwide are expanding in size at twice the rate of their population growth, leading to increased land and resource consumption per person.
To counter this trend, we could eliminate resource-intensive suburban sprawl, but cities often develop organically in ways that promote it. Factors such as wide highways and affordable fuel encourage car use and commuting, while height restrictions on buildings and separate zoning for residential and commercial areas push development outward.
Policies play a crucial role in shaping our cities for better or worse. Investing in mass transit and increasing fuel prices can motivate people to rely less on cars and live closer together, while mixed zoning laws enable them to work and enjoy leisure activities near their homes. When people live in denser environments, they tend to use resources more efficiently.
In urban settings, as in life, we face a choice: embrace sprawl or opt for vertical growth.
Urban – Relating to a city or town, typically characterized by higher population density and vast human features in comparison to areas surrounding it. – Example sentence: Urban areas often face challenges such as traffic congestion and pollution due to their high population density and industrial activities.
Sprawl – The uncontrolled expansion of urban areas into the surrounding countryside, often characterized by low-density residential and commercial development. – Example sentence: Urban sprawl can lead to increased reliance on automobiles, contributing to environmental issues like air pollution and habitat destruction.
Density – The number of people or structures per unit area, often used to describe how crowded or compact an urban area is. – Example sentence: High population density in urban centers can lead to efficient public transportation systems but also presents challenges in terms of housing and infrastructure.
Resources – Natural, economic, or human assets that are available and useful for urban development and sustainability. – Example sentence: Effective management of resources such as water and energy is crucial for sustainable urban development.
Transportation – The systems and means by which people and goods are moved from one place to another, crucial for the functioning of urban areas. – Example sentence: Public transportation systems like buses and subways are vital for reducing traffic congestion and pollution in urban environments.
Policies – Principles or rules that guide decisions and achieve rational outcomes, often implemented by governments to manage urban growth and development. – Example sentence: Urban planning policies are essential for ensuring sustainable development and improving the quality of life in cities.
Development – The process of growth and improvement of urban areas, including the construction of infrastructure, housing, and commercial spaces. – Example sentence: Sustainable development in urban areas focuses on balancing economic growth with environmental protection and social equity.
Suburbs – Residential areas on the outskirts of a city, often characterized by lower density than the urban core and a reliance on automobiles for transportation. – Example sentence: The growth of suburbs can lead to increased commuting times and a greater environmental footprint due to car dependency.
