Pollution In Nigeria: Causes And Effects Explained

Nigeria is undergoing massive changes to its infrastructure, economy, and population, leading to a noticeable and dangerous rise in pollution. The country faces a range of environmental problems, including air, water, oil, and soil pollution, which have severe consequences for the population and environment. This paragraph will explore the causes and effects of pollution in Nigeria, highlighting the impact on health, the environment, and the factors contributing to these issues.

Vehicular emissions from aged automobiles

Nigeria is undergoing massive changes to its infrastructure, economy, and population, leading to a dangerously prominent rise in air pollution. Vehicular emissions from aged automobiles are a significant contributor to this issue.

Nigeria's rapidly growing population and economy have resulted in a notable increase in the number of vehicles on the country's roads. This includes not just cars but also motorbikes, trucks, lorries, and buses. Many of these vehicles are old and have well-past-their-best engines, which can leak noxious oil vapors and emit dangerous fumes that commuters and those living near busy roads may inhale. These emissions contain various chemical compounds and fine particulate matter, including nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and black carbon, which is the main component of soot and a potent carcinogen when inhaled. Black carbon also has a significant environmental impact, as it can absorb solar radiation and convert it into heat.

The problem of emissions from aged automobiles is exacerbated by poor vehicle maintenance, the importation of old vehicles, and the use of low-quality fuel. This has resulted in a class of vehicles known as "super emitters," which produce high levels of harmful pollutants. Additionally, Nigeria, like many developing countries, lacks stringent emission standards and proper traffic regulations, further contributing to the issue.

The consequences of these vehicular emissions are far-reaching. Air pollution causes eye irritation, respiratory issues (including cough and bronchitis), and has been linked to kidney, nervous system, immune system, cardiovascular, reproductive, and developmental problems. It can also lead to neurological dysfunction, heart disease, high blood pressure, birth defects, and cancer. Vulnerable groups, such as children, the elderly, and people with respiratory infections like asthma, are particularly at risk.

To address the issue of vehicular emissions from aged automobiles, Nigeria will need to implement preventative measures. This could include gradually moving away from diesel and fossil fuels, placing emission caps on polluting industries, and improving traffic regulations and air quality standards.

Industrial waste from companies

Nigeria is a rapidly growing country with a booming economy, massive infrastructure changes, and a burgeoning population. These factors have contributed to a noticeable and dangerous rise in pollution levels, which is now receiving local and international attention due to its far-reaching consequences on the population and the environment.

One of the main sources of pollution in Nigeria is industrial waste from companies. Factories and industries emit harmful pollutants into the air and produce large amounts of dangerous industrial effluence as byproducts of their manufacturing processes. This includes emissions from the use of diesel fuels in heavy machinery, which taints the environment and poses health risks to those nearby. In addition, there is a lack of stringent measures in place to regulate these emissions, allowing them to continue unchecked.

The impact of industrial waste pollution is exacerbated by the use of older vehicles with poorer quality engines, which leak noxious oil vapors and create dangerous fumes that can be inhaled by commuters and residents near busy roads. These vehicles also emit various chemical compounds and fine particulate matter, further degrading air quality.

The problem of industrial waste is not limited to air pollution. Nigeria's water bodies are heavily polluted with untreated sewage, used plastic bottles, nylons, and solid household waste. This has led to a high prevalence of E. coli contamination, affecting about 91% of the water supply. Water pollution is particularly acute in urban areas, with coastal informal settlements like Makoko, Iwaya, and Ilaje in Lagos being severely affected.

To address these issues, Nigeria has implemented various policies and initiatives. The country is a member of the Global Plastic Action Partnership (GPAP), working to address the root causes of plastic pollution. Additionally, Nigeria is part of the Hydrocarbon Pollution Remediation Project (HYPREP) Initiative, which aims to clean up oil contamination in the Ogoniland region.

Despite these efforts, the volume of waste generated in Nigeria continues to rise, fueled by urbanization and increasing consumption. This has led to a growing industry of recycling companies, aiming to reduce the environmental impact of waste and promote a circular economy. These companies collect, sort, and recycle waste into valuable raw materials, contributing to both environmental sustainability and economic growth.

In summary, industrial waste from companies is a significant contributor to pollution in Nigeria, particularly air pollution and water pollution. The aging vehicles, diesel-fueled machinery, and lack of emission regulations exacerbate the problem. However, recycling companies are playing an increasingly important role in mitigating the environmental and health impacts of industrial waste, while also empowering communities and driving economic development.

Bush burning and biomass fuel burning

The negative impacts of bush burning are extensive. Firstly, it causes air pollution by releasing smoke, ash, and particulate matter, including harmful substances like carbon monoxide, nitrogen oxides, and volatile organic compounds. This not only reduces visibility but also poses risks to human and animal health, exacerbating respiratory and cardiovascular diseases. Secondly, bush burning leads to soil degradation by destroying organic matter and nutrients, making the soil less fertile and more susceptible to erosion. It alters soil pH and microbial activity, compromising soil quality and health.

Additionally, bush burning results in the loss of biodiversity by destroying habitats and food sources for various plant and animal species, including rare and endangered ones. It also affects their genetic diversity and evolutionary processes. Moreover, bush burning contributes to greenhouse gas emissions, releasing large amounts of carbon dioxide, methane, and nitrous oxide, which drive global warming and climate change. These emissions can influence regional and global climate patterns, including rainfall, temperature, and wind.

The practice of bush burning also has tangible impacts on infrastructure and livelihoods. The fires can damage or destroy roads, bridges, buildings, power lines, and communication networks, disrupting transportation, communication, and service delivery. Furthermore, bush burning can lead to economic losses by affecting agricultural productivity and increasing vulnerability to climate change.

Biomass fuel burning, on the other hand, is the use of solid fuels and crop residues for household energy needs. This practice also has adverse health effects, contributing to indoor air pollution. The use of solid fuels can cause lower respiratory infections, respiratory infections, and communicable diseases, resulting in a significant number of deaths and disability-adjusted life years (DALYs) in Nigeria.

Poor waste management facilities

Nigeria's waste management systems are inefficient, resulting in overflowing landfills, improper disposal practices, and severe environmental degradation. This inefficiency is more pronounced in low-income neighbourhoods, where two-thirds of urban households lack formal waste management services. The absence of waste collection services in these areas has been attributed to commercial entities' outsourcing, which considers low-income neighbourhoods unprofitable. This has led to a culture of poor waste management, with residents disposing of waste in waterways, which contributes to flooding and the washing away of land surfaces.

The inadequate waste management in Nigeria has direct implications for public health. The improper disposal of household waste provides breeding habitats for mosquitoes, rodents, and other disease-carrying vectors. This is particularly concerning in a country where malaria is endemic, with Nigeria accounting for 27% of malaria cases and 32% of related deaths globally. Poor waste management also contributes to water pollution, with untreated sewage, used plastic bottles, nylons, and solid waste ending up in water bodies.

The country's waste management issues are exacerbated by a lack of comprehensive policies, legislation, and public enlightenment programs. While the National Solid Waste Management Policy and the National Plastic Waste Management Policy have been approved, their implementation and enforcement may be lacking. Additionally, the activities of state environmental agencies are hampered by insufficient funding, inadequate facilities, human resource shortages, outdated technology, and inequitable taxation systems.

To address these challenges, Nigeria needs to adopt a holistic approach that integrates technical, economic, social, cultural, and psychological factors. Incentivizing citizens to sort their waste and promoting behavioural changes that encourage waste segregation at the source are crucial steps towards improving waste management practices in the country.

Climate change and deforestation

Nigeria is facing a dual challenge of climate change and deforestation, which are closely interconnected and have far-reaching impacts on the environment and society.

Climate Change in Nigeria

Nigeria, the sixth most populous country in the world, is experiencing significant climate change. The country is witnessing diverse environmental problems, including air pollution, water pollution, oil spillage, desertification, erosion, and flooding. Climate change has led to excess flooding in the southeast and north-central regions, a decline in rainfall in the northeastern and southern regions, and temperature increases across all regions. These changes have resulted in the loss of cultivable land, homes, and infrastructure, with economic losses amounting to billions of dollars.

Deforestation in Nigeria

Deforestation, defined as the removal of forests by humans, is a critical issue in Nigeria. The country has the highest deforestation rate in the world, with an estimated 3.7% of its forest lost annually. The main drivers of deforestation include the conversion of forest areas into farmlands to meet the food demand of the rapidly growing population, and unsustainable and illegal logging for domestic use and export. Deforestation disrupts ecosystems, leads to soil erosion, reduces biodiversity, and exacerbates climate change by releasing carbon dioxide into the atmosphere. It also negatively impacts local communities by reducing access to clean water and increasing the risk of flooding and landslides.

The Interconnection between Climate Change and Deforestation

Forests play a crucial role in mitigating climate change by providing essential services such as carbon sequestration, windbreaks, and water and air purification. They also encourage biodiversity. However, deforestation in Nigeria has led to the loss of these vital services, contributing to the country's greenhouse gas emissions and accelerating climate change.

Addressing Climate Change and Deforestation

To address these interconnected challenges, a multifaceted approach is necessary. Nigeria can promote sustainable agricultural practices, such as conservation agriculture, agroforestry, and improved seeds and fertilisers, to reduce the pressure on forests. Sustainable forestry practices, including selective logging, reforestation, and afforestation, can also help restore ecosystems and sequester carbon. Additionally, improving law enforcement and addressing corruption can reduce illegal logging and other activities contributing to deforestation.

By taking decisive action, Nigeria can curb deforestation, mitigate climate change, and ensure a sustainable future for its growing population.
