Social and Environmental Factors affecting Megacities


Megacities in general can be defined as extremely large urban centers that are home to more than 10 million people. In the recent past, there has been an extremely rising rate of these cities that is mainly contributed to by the constant rural–urban migration of a majority of people within a country. This constant rate of movement is contributed to by the rising rate of poverty. Thus, most people tend to move into urban centers to look for employment opportunities and any other opportunities that can enable them to carry out their lives look into under our study (Alam, 2018). The high population within these places normally has various problems that are exacerbated by the congestion witnessed within the cities. These challenges normally range from social and environmental challenges that we are going to look into under our study.

  1. Environmental challenges facing megacities

With regards to the high population witnessed in the megacities, there is normally an accompanying environmental threat that is associated with this large number. The large number of people normally leads to an increase in various activities such as continuous transport and more industrialization to increase employment opportunities for the people, in addition to the demand for constant energy supply for the people (Han et al, 2018). These activities have led to a high level of air pollution as a result of the harmful smoke they release into the air, thus exposing people to various health risks from the continuous inhalation of these harmful fumes. This kind of exposure to health hazards in return normally leads to a greater economic impact as people fail to be able to attend to their daily activities, thus failing to meet their monetary demands for their daily survival. Additionally, air pollution in the megacities is also normally contributed by the large amounts of garbage that is disposed off into the landfill by the people. In the process of their decay, these waste materials release an unfriendly smell into the environment, causing discomfort amongst the people living around the dumpsites. This largely piled-up waste also interferes with the overall appearance of the environment by projecting an unflattering image of the surrounding environment. In addition to the great air pollution and the general damage to the environmental beauty caused, this high numbers of people also contributes greatly to other kinds of pollution such as water pollution and even soil pollution (Ignatieva et al, 2020). Water pollution is caused at the point when the people dispose off there waste products into the water systems such as rivers and at some point even the authorities fail by directing the sew age lines into the water bodies thus greatly affecting the water systems within the city. When this kind of pollution is witnessed, the people around are normally exposed to various dangerous diseases such as cholera and typhoid that normally tend to be higher in these areas due to the poor hygiene witnessed in the area by the uncontrolled waste disclosure strategies.

In conclusion, due to the obvious negative effects of overpopulation in megacities on the environment, the government is normally obligated to adopt new strategies that will ease this type of issue by implementing suitable strategies aimed at reducing congestion in urban centers and also looking for ways of controlling various activities that have a negative environmental impact.

  1. Social challenges facing Megacities

With the high number of people living in these areas, there are normally several social issues that do arise, thus affecting the general well-being of the people in them. A majority of the people living in urban areas are normally middle-aged people. A greater number of these youths normally end up being unemployed, thus being totally idle. This factor has promoted a high level of insecurity within the urban centers as some of the youth tend to be involved in different criminal activities so as to be able to support their livelihood. Resource allocation is another issue that affects the area due to the large occupancy (Li et al, 2018). The government finds it difficult to reach out to each and every person within the city due to the overpopulation. Thus, only a few people are always getting sufficient government resources to live out quite a number of people. This act normally reflects some level of inequalities amongst the people living in those cities. Due to the higher demand for social amenities such as schools, hospitals, and other government offices within the city, there is normally a great struggle for the social amenities such as schools, hospitals, and other government offices. Traffic congestion is another pressing issue within the megacities. In the recent past, several people have resorted to owning their own private cars. This factor has led to the evidenced traffic congestion due to the excess number of vehicles on the roads, with all kinds of vehicles ranging from private vehicles, passenger vehicles, trucks, and motorcycles having to share one road at a similar time. Another problem linked to the social well-being of those people living in the megacities is the lack of family ties with the other family members they left in the rural area (Torre et al, 2021). This is typically seen in the case where a large number of people who have moved to cities do not return to their hometown but instead major in the cities.


From the discussion above, it is evident that there are several factors affecting the well-being of the people living in the megacities due to the congestion caused by the overpopulation in the area. Several people find life in the areas unbearable as a result of these factors, which range from environmental challenges to social challenges. Additionally, the government also finds it very difficult to offer equal and sufficient support to all the people in it. With respect to these factors, the government is tasked with the role of ensuring there is a regulation on the rate at which people move out of their rural areas into the cities. This one can be managed by offering alternative sources of surviving in the locality by promoting farming and even putting up industries in the local areas to offer employment opportunities to the people in the locality, thus minimizing the rural–urban migration amongst the people.
