11+ Major Global Urbanization Problems Having Devastating Effect on Our Planet

Urbanization is the movement of people from the countryside or rural areas to more developed urban areas like towns and cities. This has lead to rapid growth in these areas. The movements are usually motivated by the belief that urban areas have more to offer in terms of growth, job opportunities, and development than rural areas.

Urbanization primarily stems from the industrial revolution as it played a big part in bringing people from rural areas to the developing industrial urban areas, which had factory jobs that rendered agricultural jobs less popular. In modern times, urbanization is taking place on a large global scale as most of the development projects tend to focus more on towns and cities.

This is also evident in both developing and developed countries, as governments and municipalities allocate urban areas more resources than rural areas, which encourages urbanization.

Currently, half of the total population of the world lives in urban areas, a trend that is definitely going to continue for years to come. Despite urbanization creating opportunities for people who take the leap to look for greener pastures in urban areas, it is often faced with a lot of challenges, which this article looks at in-depth.

11+ Major Global Urbanization Problems and Issues

1. Overcrowding or Overpopulation

Overcrowding is a situation where a lot of people accumulate in a rather limited space that is unable to accommodate them without succumbing to the pressures around it properly. As a result of urbanization, overcrowding is a persistent problem as a large number of people are consistently moving to urban areas on a daily basis.

This leads to cities growing in population and getting crammed when it gets beyond their capacity. When a city is at maximum or excess capacity, people tend to compete over the limited and scarce resources such as electricity, water, transport, and the main reason they make a move, employment.

2. Unemployment

Unemployment is another urbanization problem. What is surprising is that a large percentage of young people who are unemployed belong to well raised and educated families. The job opportunities might be greater in urban areas and also pay more, but as the number of people continues to grow, the jobs become even harder to find and retain.

Companies find themselves retrenching employees as well as putting even more people out of a job. All these factors combine to create an alarmingly high urban unemployment rate.

In recent times, with the Covid-19 outbreak, the unemployment rates have also increased manifolds. With people being laid off at an alarming rate, more and more people are becoming unemployed every day. Companies are retaining just the bare minimum number of employees.

It is alarming because, with the pandemic at our door, we are facing the evils of urbanization even more. The jobs that had to be created once to meet the needs of the ever-growing urban population are being forced to shut down in the face of a huge economic crisis.

3. Housing problems

Housing problems tend to develop when people move to cities and they become overcrowded in them. If the cities were not well prepared for the numbers, the houses would become scarcer. It is even harder to settle people who come to cities and don’t end up getting employed or those who settle in as immigrants. Some of these people are unable to afford to build their own homes or even pay rent.

The problem grows in intensity as the materials required to build new houses become more and more insufficient. Limited space also makes it difficult to facilitate construction, and financial resources may even be scarce as they become primarily channeled into other development and social safety net programs other than housing. This only adds to the problem.

4. Development of slums

Urbanization and industrialization make a lot of people move to urban areas, but they do not prepare them for the conditions they are likely to face when they arrive there. Urban areas tend to have a high cost of living. The housing problems fuel this even more, as all the people who move to urban areas cannot be adequately accommodated.

This leads to the advent and growth of slums as safe havens for those who cannot afford the high costs of rent or lack substantial money to purchase apartments or build homes in urban areas. The slums arise from the construction of houses on under-developed or undervalued land due to how scarce and expensive apartments or land is in urban areas.

The houses in slums are often poorly constructed and, most of the time, lack basic amenities like clean water and proper sanitation. They are built to cater to low-income urban earners. Some of these settlements are even illegal and may be set up next to dumpsites, heavily polluted areas, or natural disaster risk areas such as swampy or mudflow areas.

5. Sanitation problems

Sanitation problems are rampant in urban areas due to the overpopulation that is seen in many of the areas where people settle. The local governments find it hard to properly set up and manage a proper sewerage system due to the rampant bulge of the human population. The fast increase in the population sometimes overwhelms the local government’s resource capacity to construct the required sanitation and sewage systems.

Sometimes, the existing sewerage systems may not have adequate human as well as infrastructural capacity to treat and manage the waste. So instead, it is drained into the water sources, polluting them and endangering the health of urban dwellers who may not only contract harmful water-borne diseases but also consume water contaminated with industrial waste and heavy metals.

6. Water shortage problems

Water is very important for sustaining life. The rampant growth of the population in urban areas makes the water very scarce as the normal supply becomes strained and inadequate to properly meet the demands of the large population.

What is more, the water problems may worsen with the increase in water pollution due to poor sewerage systems and a lack of preventive measures for managing local water pollution.


7. Health hazards

People living in congested urban areas are exposed to a lot of risks. Poor sanitation, water problems, and living in high-risk areas like next to dumpsites lead to disease of all kinds. To make matters worse, people in these areas often do not have proper access to health care services, which makes the disease much harder to cure, and at times, it can even lead to death.

In the slums, people are often diagnosed with diseases like infertility, food poisoning, allergies, asthma, cardiovascular complications, respiratory failure, cancer, and death. This can all be accredited to the overall pollution that is experienced in these urban areas.

The problem that global urbanization poses can be felt even more with the onset of the Covid-19 pandemic. Now that social distancing has become absolutely essential, urbanization has become the greatest health hazard of all time. In developing countries, especially, the problem is worse

The slum areas are the worst affected. It is in these areas that the pandemic is spreading at a much higher rate. In most cases, as reported here, the cases are severe, and the fatality rate is very high. It is worth mentioning here that when the pandemic started spreading in India, people were really concerned about it spreading in Dharavi, India’s largest slum situated in Mumbai. When it spread there, it was by sheer luck that it could be controlled at the earliest.

8. Degraded environmental quality

This is one of the most common effects of urbanization. The congestion of people in limited spaces and areas reduces the quality of air, contaminates water, and pollutes the noise and land.

This leads to very poor environmental conditions for people to live in and is often detrimental to the health of these people. There is also a need to improve the infrastructure so as to accommodate the rise in population by erecting new buildings and amenities.

This leads to the destruction of forests and natural habitats in order to acquire the materials required. Industrial waste poured into the river and lakes contaminates the water, and the noise brought about by the numerous human activities carried out sums up the many effects urbanizations brings to slum areas.

The greater the urban population, the more pollution is caused by automobiles. Although carpooling is a relatively better practice, not everyone has come to terms with it. Most people prefer to use their personal vehicles. Even if people opt for carpooling or public transport, it does not really help much.

Every day, millions of people avail themselves of the commute, which means tens of thousands of vehicles run on the streets every single day. Most of these vehicles run on fossil fuels and, as a result, cause an immense amount of air pollution and degrade the quality of the air considerably.

9. Disposal of trash

Urbanization has led to many factors that have made trash disposal very difficult. Urban cities produce a lot of waste on a daily basis that they cannot properly dispose of. This subjects the people living in these areas to multiple health risks.

The areas that were initially set aside to accommodate trash disposal needs have become full, and some of them are inhabited by slum people who move close to such areas.

Diseases are easily spread, with some often spread by the insects and animals that frequent the dumping site areas and then get into contact with the water that people consume. The trash fills are also located in areas where people live, which subjects them to many of these health hazards.

10. Transportation problems

A lot of people are often moving around in between their workplaces and their homes; this more often leads to traffic jams and congestions. The number of people who own cars is growing every year, especially in urban areas, and the public transport system is very unreliable.

The number of cars is increasing, and as a result of this, the traffic problems continue to worsen. This does not only lead to blockages in traffic but also increases the chances of people getting involved in traffic accidents and urban air pollution.

11. Urban crime

The more people are congested in urban areas, the higher the rate of unemployment, as the available jobs are not enough to accommodate all. Resources have also become scarce, and not everyone has access to essential social services, which leads the disadvantaged to get into substance abuse, violence, burglary, and organized crime.

Lack of employment also increases poverty, which, as a result, makes it even harder for people to get the essential things they need to survive. People then turn to poverty-related crimes such as theft, conning, and organized crime as a way of earning a living.

Such criminal activities, mainly those rampant in urban areas due to poverty and lack of job opportunities, include kidnapping, robbery, carjacking, rape, and even murder. These acts make cities very hard for people to live in as they are not guaranteed their safety, especially for victims who cannot defend themselves in such situations.

12. Increased rates of poverty

Global urbanization ultimately leads to poverty. As the rate of unemployment increases, more and more people continue to sink beneath the poverty line. Also, as the population increases and the urban areas become more and more congested, the state government starts losing track of the population.

As it does so, in some cases, it also fails to provide for all the people adequately. It ultimately leads to extreme forms of poverty where people have to live on the streets with only a little or nothing to eat or drink.

As a result of poverty, the standard of living of people also decreases to a point where it can sometimes be rendered inhuman. In a world where the rich are constantly becoming richer and the poor are constantly becoming poorer, poverty is by far one of the largest threats to human existence.

13. Malnutrition

Urbanization causes malnutrition, especially for poor families in the urban areas of a country. As basic needs are more expensive in the cities, poor families do not have enough resources in order to purchase healthy and complete food for themselves.

With the lack of nutritious diets, the poor areas are experiencing more illnesses as they are more susceptible to infections, which then cause loss of appetite and then malnutrition. Furthermore, urbanization causes a lot of environmental contamination, which causes the food ingredients to be filled with toxic chemicals.

For example, street foods are prepared unhygienically, which leads to the spread of food-borne diseases. The lack of nutrition intake, and micronutrient deficiency weaken the immune systems of people, making them more susceptible to diseases. This shows how urbanization leads to undernutrition, especially among the poor.

With more sick and underweight people, the environment is being affected by the lack of a proper state of mind of people, leading to more irresponsible and careless actions that disrupt the planet.

14. Obesity

Obesity is another major global urbanization problem. As urbanization continues, more physical spaces are being occupied, leading to fewer spaces for people to move about.

People continuously eat food from time to time while they are only doing low-energy expenditures like working in front of a computer. Due to the lack of physical movement required in an urbanized area, while the stress and mental demands of the job are too much, leading to more calorie intake, people are becoming obese.

Recreational activities are not prioritized in urbanized areas because people are constantly working to keep the city developing. Without any engagement in physical activities, people are continuously gaining weight without any means of burning some calories.

With more obese people, more food is being produced and consumed, while the areas for plants and animals to grow are becoming more constrained. With that, the environment is being affected, as resources are becoming way fewer while people are consuming them way faster.

15. Environmental Hazards

Urbanization leads to the development of land areas that used to be filled with trees and other plants that help reduce the risks of natural disasters. Due to urbanization, more trees are being cut, resulting in fewer plants to absorb carbon dioxide and help in reducing flash floods and land slides.

With more urban developments, there are less areas for plants to grow in the cities, which leads to such hot weather, contributing a lot to the emission of greenhouse gases and the severity of global warming.

Other than that, with more urbanization, more resources are also needed, meaning more trees are being cut in the forest to provide paper and other materials needed by urban developers.

This leads to more environmental hazards, as the less forest we have, the more at risk we could be from natural calamities. For example, most cities are usually flooded when a typhoon or hurricane hits the area. It shows how the lack of plants in the cities leads to less absorption of rain water, leading to flash floods.

16. Decrease in Animal Population

Connected with more rural areas being converted to cities, the habitats of animals are being consumed as well. With more forest being cleared for more urban resources, more wildlife is being jeopardized, leading to a decrease in their population.

As more habitats are being destroyed, the animal population is continuously decreasing. Furthermore, the major effects of urbanization, like global warming, are also affecting the animal population.

For example, glaciers are melting in some areas of the world, leading to the destruction of animal habitats like those for polar bears. With that, more animals are dying, which could possibly even lead to the extinction of some animal species.

Furthermore, due to urbanization, animals are losing their food sources as well. With that, more animals are dying, leading to a decrease in their population. Aside from that, even if some areas are not converted to cities, urbanization still affects them.

With urbanization’s waste being thrown into the ocean and land, and smoke in the air, more implications for animals are happening. Some animals die due to inhaling toxic chemicals from urban areas; some die due to eating plastic waste and other toxic urban waste; and some die due to the lack of clean areas for them to inhabit as they are filled with urban waste.
