Race

One cause for urban sprawl may be race. There are some examples in the suburbs of urban areas where many people of the same race live in communities. This is quite logical since they often share the same values. Thus, race can be a factor for urban sprawl.

Religion

Another cause for urban sprawl can be religion. Since people are often discriminated because of their belief systems, minorities may decide to leave the cities and settle in rural areas in communities where they are free to live their beliefs.

Age

Age is an additional important factor in order to explain the phenomenon of urban sprawl. Younger age groups that search for jobs are usually striving to live in cities. However, older people who are already retired may leave the cities since they do not have to work anymore and want to live their lifes in more quiet neighborhoods near nature.

Cultural factors

Cultural differences are another cause for urban sprawl. Especially in big urban areas, there are many people who have different kinds of cultural values. This may lead minorities to leave the city if they are not accepted by the main cultural streams and thus, they are likely to relocate to urban areas where they can life their lifes in line with their cultural values.

Access to appropriate housing

In big cities, housing prices are usually quite high. Many families are not able to afford to buy a home in these areas. Thus, if they want to own a house, they have to leave the city and settle down in some cheaper places.

Low price for public transportation systems

The public transportation prices are usually quite affordable in big cities. Using the train from suburbs to the city center often is not a big financial issue. Thus, especially in areas where public transportation systems are reliable, people may decide to live in suburbs and commute by train in order to get to their work locations. Therefore, low prices for public transportation may also contribute to the urban sprawl problem.

Increasing numbers of jobs in suburbs

Moreover, in some areas, the number of jobs in suburbs increased in the last years. Since many firms are not able to find affordable office or production spaces in the cities, they locate their businesses in suburban areas.

 

Therefore, the number of jobs in suburbs increases, which makes it more attractive for people to live here. Thus, the incentive for people to move to these areas increases, which also increases the probability of urban sprawl.

Commuting networks

In the last decade, several commuting networks have been established which make commuting quite cheap. Moreover, services like Uber are a good alternative compared to the use of taxis and are also significantly cheaper in many areas. As a result, commuting became more attractive and an increase in urban sprawl is likely to result from these new possibilities.

Improvement in infrastructure

Especially in rural areas, the infrastructure has often been improved significantly over the last decades. This improves the living conditions of people in these areas. Therefore, even people currently living in cities may consider relocating to suburbs instead. This is especially true for families. If there is a good infrastructure, families can combine a quiet life in rural areas with all the amenities they would also get in cities.

Land rates

The cost of land for building houses is often much lower in suburbs than in the cities itself. This gives people the incentive to relocate to urban areas in order to be able to afford a house for their families instead of a flat. Thus, lower land rates in suburbs compared to cities are likely to contribute to urban sprawl.

Insufficient planning efforts

Many people in our society suffer from a high level of stress from their jobs. Thus, when they come home from work, they want to live in an environment where they can relax and reload their batteries. However, in many cities, this is not possible since there are not enough quiet areas.

 

Especially in the city center, there is much noise and other things that adversely impact peoples‘ psychic conditions. Thus, in order to be able to have enough space to relax, people may move to suburban areas where they can find peace after work.

Increase in living standards

In our nowadays society, we got used to quite high living standards compared to past generations. This implies that we also want to consume many material things. In order be able to do so, people may move from cities to suburbs since they can save on their housing expenses. This saved money can now be used for additional consumption.

Population growth

The number of people populating our planet steadily increases. However, the living spaces in cities are quite confined. This means that many people have to live in the suburbs instead of cities. This phenomenon leads to a natural increase in urban sprawl.

Tax rates

In many areas, tax rates for housing as well as for businesses are lower in rural areas compared to cities. Thus, people have an incentive to live in suburbs rather than in cities since they can save quite a lot of many which they can spend on other things.

Individual preferences

Many people do not like to live in big cities. Instead, they may prefer in more quiet areas near nature where they can avoid the stress that comes with living in big cities. Thus, individual living preferences may lead people to leave the cities and relocate in suburbs.

Effects of Urban Sprawl

  1. Concentration of poverty
  2. Increase in traffic
  3. Increase in energy consumption
  4. Increase in pollution
  5. Shortage of financial resources
  6. Insufficient quality of education
  7. Changes in social life
  8. Increase in public costs
  9. Health effects
  10. Psychic problems
  11. Environmental effects

Concentration of poverty

Urban sprawl can lead to a concentration of poverty. This can often be observed in big cities where some suburbs suffer from a quite severe concentration of poor people. This concentration of poverty is also likely to increase crime rates since poor people are often desperate due to their living conditions and thus have a higher level of frustration.

Increase in traffic

Since the number of people who have to commute to work increases with an increase in urban sprawl, the traffic is likely to increase accordingly. This leads to more congestion on streets and also to a loss of time for many people.

Increase in energy consumption

Building appropriate infrastructure in rural areas is quite costly. This also translates into an increase in energy consumption. Thus, urban sprawl is likely to lead to a higher overall energy demand.

Increase in pollution

The increase in traffic also leads to an increase in pollution, especially in air pollution. Since most of our cars need fossil fuels, harmful gases are emitted through commuting on a daily basis.

 

These gases include CO2 which also contributes significantly to the global warming issue. Moreover, the increase in energy consumption due to urban sprawl also causes additional types of pollution. Thus, urban sprawl and the level of pollution are closely linked to each other.

Shortage of financial resources

Many people will no longer be able to afford to live in cities since their salaries are not high enough to cover their living expenses. This problem is especially severe in cities which have high housing prices but wages are usually appropriate. For this group of people, there is no choice since they will simply be forced to move to the suburbs due to financial pressure.

 

However, moving to suburbs may not solve the financial problem. The financial pressure may instead get even more severe if people will not be able to find a new job. Thus, moving from cities to suburbs can be a good financial choice, but it does not necessarily have to be.

Insufficient quality of education

The quality of education is usually quite good in big cities. There are many good schools and also good universities. The quality of education usually decreases significantly when we look at suburbs or rural areas. This is due to the fact that cities often get much higher financial support from governments in order to supply good education.

 

Rural areas usually have less financial support and thus the quality of education is likely to suffer due to that. This may lead to a lower education quality for children whose parents moved to suburbs. Thus, urban sprawl can cause lower levels of education for some groups of people.

Changes in social life

Urban sprawl can also cause changes in our daily social lifes. Since outside of cities, the settlement density usually is much lower than in cities, the interaction between people may be reduced because of that.

 

In cities, you can easily meat many friends on a daily basis since the distances between you and your friends are quite short, but this may be different in rural areas where the distance can be many miles.

 

Moreover, rural areas often lack reliable public transport, which makes it especially hard for people who do not have a car to meet their friends. Thus, urban sprawl can indeed have a significant impact on our social lifes.

Increase in public costs

There are also high public costs related to urban sprawl. This includes infrastructure costs, but also costs from pollution. Infrastructure is quite expensive in areas with low settlement density since streets have to be build and will be used by less cars compared to cities. In addition, the pollution from commuting results in further social costs since air pollution causes acid rain and also contributes to global warming.

Health effects

Urban sprawl can also have several adverse health effects. On the one hand, the supply with doctors and hospitals usually is far worse in rural areas or suburbs compared to the cities. Also, the quality of medical education may be worse in many cases. Moreover, since people have to commute for quite long times, they are likely to suffer from overweight and related

health conditions like high blood pressure which can result in cardiovascular diseases.

 

Psychic problems

For humans, it can be quite challenging to adopt to the new living conditions in suburbs or even in rural areas when you have been used to the city lifestyle for a quite long time. When you leave your home and move to a new place, you often leave many friends and your lifestyle behind. This may be quite challenging to many people. If people are not able to adopt properly, this may lead to psychological problems which can turn into psychic costs.

 

Environmental effects

If people move out to places which have previously not been touched by humans at all, the surrounding environmental system may be harmed. Animals which live in this area may leave and therefore the environmental system is likely to change. Moreover, the living space for many animals and plants is likely to be destroyed since the building of infrastructure often results in deforestation and other measures which are harmful to the local flora and fauna.

Solutions to the Urban Sprawl Problem

  1. Local planning policies
  2. Financial incentives
  3. Building permit limits
  4. Urban growth boundaries
  5. Tax discrimination
  6. Land acquisition of local governments
  7. Reduce the number of private car ownerships
  8. Higher taxes on fuel
  9. Higher taxes on change in land use
  10. Increase residents‘ share of infrastructure costs
  11. Assure affordable housing
  12. Tolls
  13. Education

Local planning policies

In order to meet the problem of urban sprawl, local planning policies can be quite effective. This means that municipalities take efforts that people stay in cities and do not settle down in suburbs or rural areas. This can be accomplished by increasing the living quality in cities compared to suburbs. This may include improving the public transport or ensuring a higher quality of education so that people are happy to stay in the cities.

Financial incentives

Financial incentives may be another effective measure for fighting sprawl. These incentives can come in several ways. For example, financial incentives can mean that people who live in the cities may be paid higher wages by companies than people in suburbs to cover the higher living costs. It may also come in a way that public transport is subsidized in cities so that people also can save money on that and thus have more income to spend on other things.

Building permit limits

Another way to confine sprawl is to set building permit limits in suburbs. This is an easy but yet quite effective way. If these limits are quite strict, they lead to a significant reduction in urban sprawl since people are simply not able to build their homes in the restricted areas.

 

Therefore, more people are likely to stay in the cities instead of moving to suburbs. Moreover, by setting strict building permit limits, it is likely that the prices for buildings in suburbs increase. This makes it even more favorable for people to stay in the cities instead of moving.

Urban growth boundaries

Another related measure are urban growth boundaries. This means that a specific area is an area inside the boundary is used for urban development while the area outside the boundary is used for agricultural or other purposes, but not for settlement. By using this boundaries, urban sprawl can be effectively mitigated since it is clear in advance where buildings are permitted and where they are prohibited.

Tax discrimination

Local authorities can also use tax discrimination in order to fight urban sprawl. This means that municipalities could charge less taxes on certain services if people live in cities compared to suburbs.

 

This may also include the tax on housing. If taxes are lower in cities, people have a stronger incentive to stay or move there. Moreover, authorities may also charge higher taxes on fuel to make commuting less attractive. This will also make the city life more attractive compared to the suburban life.

Land acquisition of local governments

Another measure against sprawl is a land acquisition of local authorities or governments. Through the acquisition of land, these authorities have control on how this land is used in the future. By acquiring land in suburbs or rural areas, authorities may prohibit the building of houses in these areas and rather make them available for reforestation or farming purposes.

Reduce the number of private car ownerships

A rather unpopular but quite effective way to reduce the problem of sprawl would be to reduce the number of private car ownerships. Setting limits for the overall number of cars that can be registered would give people the incentive to stay in the cities since they have not the necessary mobility to commute to work.

Higher taxes on fuel

Urban sprawl could also be mitigated by raising the price for fuel. This could be accomplished by setting higher tax rates. Through the increased price of fuel, people would have an incentive to reduce commuting. This in turn would mean that it becomes more attractive for people to stay in or move to cities instead of living in suburbs.

Higher taxes on change in land use

If people own pieces of land that they now want to use for housing purposes, they have to get a permit for the change in land use. These changes in land use could be taxed at a higher rate so that it would become more unattractive for people to turn their agricultural land into housing land. This may in turn also mitigate the problem of urban sprawl to a certain extent.

Increase residents‘ share of infrastructure costs

Infrastructure costs in rural areas are likely quite high since all sorts of infrastructure has to be provided to a relatively small number of people. Thus, the cost of infrastructure per person is usually much higher than in cities.

 

A measure that would mitigate this problem and would also lead to less urban sprawl is to increase the residents‘ share of this infrastructure costs. On the one hand, the costs for municipalities would be reduced. On the other hand, also the incentive for people to move to rural areas or suburbs would also be reduced.

Assure affordable housing

Housing prices are a big issue, especially in big cities. It is quite common that people are not able to afford a house with an average income in these areas. Thus, people have the incentive to leave and settle down in areas with lower housing expenses. Local authorities may therefore subsidize living in these areas in order to prevent people to leave.

Tolls

Tolls on streets which have a high level of commuting may be another way to make commuting more unattractive and thus the city life more favorable compared to living in suburbs.

Education

Education is an important incentive for people to stay in the cities, especially for families with young children or also for students. If the level of education is much better in cities, people will have an incentive to stay or move there. Thus, local authorities have to make sure that the education level in cities is better than in suburbs in order to make people stay in the cities.

Conclusion

Urban sprawl can have significant severe consequences on our daily lifes and also on the environment. There are several measures that can be taken in order to mitigate this problem. In general, governments and municipalities should give people the incentive to stay in the cities.

 

If people have a high living quality in cities and are also able to afford to live there, there will be no reason to move to suburbs and thus the problem of urban sprawl can be confined.
