What You'll Learn
Fossil fuels, industrial emissions, and transportation
Fossil Fuels
North African countries like Algeria, Libya, and Egypt have fossil fuel-based economies. Fossil fuel use, particularly in energy production, is a major contributor to outdoor particulate matter pollution (PM2.5) in Africa. Fossil fuel companies continue to exploit local resources and transfer wealth out of the continent, perpetuating a colonial-era economic structure. Additionally, the push for green hydrogen in Europe has led to the extraction of hydrogen from fossil gas, allowing fossil fuel companies to maintain their infrastructure.
Industrial Emissions
The rapid industrialization and economic expansion in North African countries like Algeria, Egypt, and Angola have led to increased pollution. The relationship between industrialization and pollution emissions is evident, with these countries experiencing environmental degradation. Weak environmental laws and regulations may also attract foreign investors, influencing the region's industrial development.
Transportation
The Northern Corridor, one of Africa's busiest transport routes, is a hotspot for pollution and greenhouse gas emissions. Up to 3,000 trucks travel through it daily, contributing to air pollution and the health issues associated with it. Tailpipe emissions from freight transportation between countries like Rwanda and Kenya have severe respiratory impacts on drivers and residents along the route. Efforts to improve fuel efficiency and reduce emissions are underway, supported by organizations like the United Nations Environment Programme (UNEP).

Poor waste management
North Africa is one of the most water-scarce regions in the world, and the entire region is expected to be one of the most vulnerable to climate change. The region is facing an air pollution crisis, with the air quality gap between the recommended levels by the World Health Organization (WHO) and the actual levels in the region increasing every year.
The primary sources of air pollution in North Africa are industrial emissions and construction to support rapid urbanization. In 2019, air pollution was the second leading risk factor for death across Africa, with particulate matter pollution (including ambient PM2.5 and household air pollution) being the leading risk factor for deaths across the continent. The death rate linked to air pollution in Africa is almost double the global average.
Weak waste collection systems in Africa, combined with uncontrolled and controlled dumping of waste, are causing significant economic, social, and environmental impacts. The indiscriminate dumping of waste in urban areas creates risks of disease, flooding, and environmental pollution. Research has shown a correlation between proximity to open dumpsites and the incidence of diseases such as cholera, malaria, typhoid fever, and dengue.
The rapid urbanization witnessed in developing countries in Africa has led to a substantial increase in municipal solid waste (MSW) generation. However, the corresponding disposal strategies, along with constraints in land resources and finances, have resulted in ineffective policy implementation and monitoring.
Furthermore, the illegal import of hazardous waste from the Global North to the Global South is a significant concern. Criminal organizations often facilitate such illegal imports, despite the Basel Convention's ban on waste imports from Northern to Southern countries. African countries must implement appropriate management practices for agricultural waste in rural areas to avoid improper disposal methods such as dumping or burning.
To address the waste management challenges, Africa can focus on waste sorting at the source, optimization of landfill practices, thermal treatment measures, and strategies to capitalize on the value of waste. Proper waste management contributes to a cleaner and healthier environment and creates safer job opportunities.

Water scarcity and pollution
North Africa is one of the world's most water-scarce regions, making it particularly vulnerable to climate change. The region is expected to be one of the most vulnerable to the climate change "hot spot", with significant health implications. The World Resources Institute labels Libya as suffering from extreme water stress, while Tunisia, Algeria, and Morocco are considered to be under high water stress, and Mauritania faces medium to high water stress.
Water scarcity in North Africa has been exacerbated by rapid population increases, rising income levels, and growing urbanization. The ongoing conflict between Morocco and Algeria over the Western Sahara has also resulted in mismanagement and overexploitation of the basin's water resources, leading to dangerous levels of nitrate pollution. The improvement of water quality and management in this region requires bilateral cooperation between the two countries, including the exchange of scientific data and increased technical cooperation.
North African communities have a long history of water management and governance, with millennia-old underground water channels and other methods of water storage and collection. However, the growing global climate emergency is placing greater stress on the region's water infrastructure, as the level, intensity, and variability of seasonal precipitation are changing. Climate change and global warming, mainly caused by an increase in human and commercial activities, contribute to water scarcity in North Africa. Rising global temperatures have intensified the hydrological cycle, leading to drier dry seasons and more extreme and frequent droughts, reducing the availability, quality, and quantity of water.
Agriculture, one of the most pivotal economic sectors in Africa, is heavily impacted by water scarcity, leading to food shortages and, in the worst cases, famine. In times of water scarcity, people often resort to contaminated water sources, resulting in widespread diarrhoeal diseases, including cholera, typhoid fever, and salmonellosis. Air pollution, largely attributed to industrial emissions and construction, is another critical issue in North Africa, with particulate matter pollution (PM2.5) being a leading risk factor for deaths in the region.

Deforestation and soil degradation
North Africa is facing a pollution crisis, with the region becoming increasingly vulnerable to climate change. The burden of air pollution on African livelihoods and population health is among the highest in the world, with particulate matter pollution (including ambient PM2.5 and household air pollution) being the leading risk factor for deaths across the continent.
Deforestation is a major contributor to this pollution crisis. While deforestation has decreased globally in recent years, the rate of loss of forest area in Africa has increased steadily since 1990, weakening the continent's ability to withstand climate change. Forests play a crucial role in maintaining a healthy environment, acting as watersheds, defending against soil erosion, regulating local weather conditions, and trapping greenhouse gases.
In North Africa, the Sahara and Sahel regions are particularly affected by deforestation. The Great Green Wall Initiative was launched in 2007 to address this issue by planting millions of trees across an 8,000km-long corridor in the Sahel region. The initiative aims to moderate temperatures, wind patterns, and soil erosion, as well as increasing humidity for agriculture. However, progress on the project has been slow, and the region continues to face severe deforestation rates.
Soil degradation is another critical issue in North Africa, caused primarily by soil erosion, desertification, deforestation, and poor agricultural practices. The removal of vegetation has reduced the soil's ability to retain moisture, impacting agricultural productivity and food security. Africa's forests and woodlands are being depleted, threatening one of the continent's most important resources. Nearly 4 million hectares of forest and woodland are being lost or degraded annually, largely in West Africa.
The effects of soil degradation are widespread, including the loss of fertile land and biodiversity, increased carbon dioxide and greenhouse gas emissions, nutrient depletion, and loss of ecosystem services. In North Africa, the combination of deforestation and soil degradation has led to a decrease in agricultural production yields, further exacerbating the region's food security issues.
To address these issues, various solutions have been proposed, including afforestation of degraded land, integrated landscape management, and effective soil conservation measures. Community engagement, education, and policy implementation are also crucial in combating deforestation and soil degradation in North Africa.

Indoor air pollution
North Africa is one of the most water-scarce regions in the world, and climate change is expected to have a significant impact on the region. There is a lack of data on air quality in North Africa, but it is known that outdoor air pollution is a major cause of mortality, with 3.4 million deaths attributed to it between 1990 and 2019. North Africa experiences high levels of PM2.5 pollution, with Egypt, Niger, Mauritania, and Nigeria having some of the highest concentrations on the continent.
The health consequences of indoor air pollution are significant. Inhalation of small soot particles can penetrate deep into the lungs, inflaming the airways and impairing respiratory functions. Prolonged exposure to indoor air pollution has been linked to an increased risk of chronic obstructive pulmonary disease (COPD), with women having more than double the risk compared to those using cleaner fuels. Men, who already have a higher risk of COPD due to smoking, almost double their risk with exposure to household air pollution.
Additionally, indoor air pollution is a contributing factor to 12% of premature deaths due to stroke and 11% of deaths from ischaemic heart disease. It is also associated with low birth weight, tuberculosis, and various cancers. The use of solid fuels and kerosene for cooking and heating has severe health implications, causing approximately 3.8 million premature deaths annually.
Addressing indoor air pollution is crucial for improving public health and reducing mortality rates. While some countries in North Africa are implementing policies to improve air quality, such as waste management initiatives and the expansion of electric vehicles, more comprehensive measures are needed to tackle the region's air pollution crisis.
