South Africa is a country of stark contrasts, challenging stereotypical views of Sub-Saharan Africa. While poverty, water scarcity, and disease are prevalent in many areas, South Africa also boasts modern cities similar to those in the United States. However, the nation faces significant environmental challenges that demand attention.
South Africa's diverse landscape faces numerous environmental challenges.
Three Main Environmental Issues
There are three main environmental issues in South Africa - pollution, lack of energy, and deforestation.
- Pollution: A major contributor to climate change and air pollution.
- Lack of Energy: Characterized by frequent blackouts and heavy reliance on coal.
- Deforestation: Exacerbates pollution and energy shortages.
The order of these issues is determined by their impact on the environment and the chain reactions they trigger.
10 Major Current Environmental Problems
Deforestation: The Root of Many Problems
Deforestation is arguably the most significant environmental problem in South Africa. Without the extensive cutting down of trees, paving of roads, and construction of buildings, pollution levels would be significantly lower.

Deforestation is the biggest problem because more problems are caused than solutions are found - in other words, more pollution is being put in through the use of machines and also chemicals released through the process of cutting trees down. Not only that, but South Africa and other countries as well, has lost more than 50% of its forests, most of which are standing in the last 10-15% left (Malentaqui). The process of a slowly dying planet can be sourced through one of the biggest problems of deforestation since it leads to less oxygen, more creation and consumption of goods, and more people occupying less available land.
At the rate the city grows, the ecosystem is already facing a problem of balance between natural life and human needs.
Deforestation in Africa contributes to soil erosion and climate change.
Energy Crisis: Reliance on Coal
Lack of energy is the second problem in South Africa because despite the stereotypical view of Africa as a dry and barren area with no electricity, the city life in South Africa faces a lot of blackouts, and not short blackouts - a typical blackout lasts several hours. The lack of energy is due to reliance on the current source of energy - which is mostly coals.
Because coals are a type of energy source that is often used and released into the air, it creates not only environmental problems, but also electricity problems ("South Africa's Energy Crisis"). Not only that, but the lack of maintenance of the factories contribute greatly to this city's lack of energy. The excessive use of coals makes it uneasy for factories to remain clean and the old infrastructure of energy has long passed the old days of electricity.

Pollution: A Significant Impact
Pollution has the least profound effect, but nevertheless, has a significant impact on South Africa's environment. Without the deforestation of land, there would be less pollution. However, it is still an important issue because of the effect it has both in terms of macro and microclimate.
The widespread use of cars has led to the high level of traffic in South Africa - in a city of 52 million people, for every 1000 people, there are 162 cars, making a total of 8.42 million cars ("South Africa Environment Issues & News"). This amount of cars contribute to both air pollution and water pollution - to fuel the cars, exhausts gases must be released and oil must be put into the cars; oil that can no longer be used are dumped in the waters and pollute the waters.
As stated before about the use of oil, South Africa is also a city where a lot of oil is also transported into the city. With that, more pollution occurs when oil spills and dumping of oil occurs. Because of the high population in the city, the frequent use of oil creates more pollution in the city.

The Role of Information Technology
A few ways information technology and the issue of pollution are related is through developing more accurate numbers of the amount of pollution in the city, as well as bringing new ways of reducing the amount of pollution through smart motor systems and creating more environmentally friendly buildings (Hodge). This new advancement provides South Africa with new ideas and solutions; with them, it becomes the first step taken to reduce the large amount of pollution in the city.

The issue of unclean air, water, and environment is increasingly becoming one of the main environmental issues in many countries; where the government is forced to take part, along with several organizations, to fight for the planet's cure (Lubbe). In several other sources, deforestation is also a common issue, not just in South Africa, but also in other countries.
According the "The Practical Social Media University," the government's use of IT in order to post things for the citizens to read, such as amendments, propositions, and proposed solutions for issues around the world, has become a common way for news to be spread. Not only does the internet provide ways for people to become aware of the current problem, but it also helped reinforce the issue for people outside of South Africa so that they can become aware of this problem and help.
One of the last ways that IT has helped in the problem of pollution is through the use of communications between countries in order to help combat it - not just in South Africa, but also in order countries. Ambassadors from around the world gather together in order to discuss issues all over cities and with the current day technology, it has increasingly become easier for communication between these people to happen, rather than meeting together a few times in a year (Hodge). The given age of Skype, cell phones, and even Google Hangout has allowed our leaders to meet together to learn ways to help prevent a city from becoming over-polluted and to share advice to the people as well as other cities.
Broader Environmental Issues in Southern Africa
There are a range of environmental issues in Southern Africa, such as climate change, land, water, deforestation, land degradation, and pollution. The Southern Africa region itself, except for South Africa,[1] produces less carbon emissions but is a recipient of climate change impacts characterized by changes in precipitation, extreme weather events and hot temperatures. Through an attempt of keeping up with the developing world and trying to meet the high demands of the growing population, Southern Africa has exhausted its many resources resulting in severe environmental damage.
Southern Africa consists of countries such as: Angola, Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Zambia, and Zimbabwe. Some environmental issues that affect Southern Africa are: water pollution, air pollution, land degradation, solid waste pollution, and deforestation.
Water Scarcity
One of Southern Africa's biggest issues is the lack of clean water. Many Africans are moving to rural areas, adding to the already high demands for clean water and while demands are growing drastically, freshwater supplies remain limited. Adding to the high demands, Durban’s dam has decreased by 20% since 2010, and up to 30% of the water has either been stolen or given away illegally through international trading.
“A review of water availability in 1996 estimated that the total average annual surface runoff was 150 million cubic metres, the maximum potential annual system yield was 33 290 million cubic meters, and total water annual requirements were 20 045 million cubic metres. Although South Africa has of the best, cleanest water out of all the countries in Southern Africa, many don't have access to basic sanitation.
A majority of Southern Africa's accessible water is unclean, making the water vulnerable for water transmitted diseases to exist. As the population of people moving to urbanized areas increase, the demands for food supply also grow. As a mean to keep up with these high demands, the use of fertilization and sewage contamination also incline. Chemicals found in fertilizers and sewage wastes can cause diseases , which is harmful to other species in the environment.
Oil Spills and Coal Mining
South Africa is situated at the very tip of Southern Africa. This location causes South Africa to become very vulnerable to oil spills. High levels of oil is transported from the Middle East to Europe and America along the coast, making Southern African's water and ecosystem at risk to being severely damaged.
Coal mining is one of Southern Africa's main energy source, but it holds a huge negative impact on the land's water, air and soil quality. Acid mine drainage is the result of the excess coal mining that occurs. Sulphuric Acid is released from coal mining, and although the generalizing process is slow, the time it takes for the acid to neutralize is equally as slow. When clean, excess water is released from the rock masses that are broken through mining, it's mixed with the sulphuric acid causing the water to become toxic. This toxic, contaminated water kills plants and animals, while also dissolving aluminum and heavy minerals found in clean water (increasing toxicity level).
Air Pollution
During the winter, pollutants are trapped in the air due to the high pressure, and are unable to move or dissipate. In the summer, due to the low pressure, pollutants are dissipated through unstable circulation. 75.2% of Southern Africa's energy come from Highveld Areas, where 5 of its 10 Eskom Power Stations are the largest in the world.
Highveld areas are above sea level, making the oxygen level 20% less than the oxygen level in the coast. This results in an incomplete combustion of fossil fuels, and a severe nocturnal temperature inversion to occur; which results in smoke being trapped in the air. 860 tons of SO2 is produced from 3 of their main power stations (Matla, Duvha and Arnot), “which exceeds the World Health Organisation’s (WHO) [exposure to particulate matter] standards of 180 mg.m-3 by 6 to 7 times during winter months (Annegarn et al.
Waste Management and Land Degradation
With the increase of population, and an increase in people who are moving to urbanized areas, the number of solid waste produced is increasing. With the decrease in water and the high demands for agriculture, Southern Africa's land is becoming less fertile. Climate change is also causing an increase in water evaporation from the soil, making it very difficult for produce in Southern Africa.
Desertification causes an increase in soil erosion, making it difficult for plants to grow. This will lead to unsustainable food, and endanger Southern Africa's wildlife. Through time, soil erosion will result in harvesting alien plants. Southern Africa's land is already over cropped and over-grazed as a result of Africa's undistributed lands. Many countries use the method of irrigation as a way to prevent desertification and droughts.
Key Statistics
Below is a table highlighting key statistics related to water and waste management in South Africa:
| Statistic | Value |
|---|---|
| Investment Needed in Water Infrastructure (per year) | R90 billion ($5.21 billion) |
| Projected Water Usage Increase by 2030 | 17% |
| Drinking Water Microbiologically Unsafe (2022) | 46% |
| Tap Water Considered Non-Revenue | 47% |
| General Waste Produced Annually | 6 million tons |
| Waste Recycled | 30% |
Environmental Justice in Informal Settlements
Challenges related to environmental justice are characterised by the inadequate provision of energy resources, risks of the communities to pollution, inadequate waste management services, and susceptibility to water related diseases due to lack of water and sanitation services. The Kosmos informal settlement does not have electricity, and the community relies on firewood and paraffin fuelled stoves for household water heating and cooking. Collection of firewood is a daily hustle for the community of Kosmos informal settlement, with twice weekly collections necessary to meet their energy demands. The use of firewood is prevalent within the Kosmos informal settlement.
