The Clean Air Scenario for Prevention of Air Pollution in Africa
Almost everyone in the world knows that air pollution is a huge problem. There are many sources of pollution, from traditional to modern. Some of these sources include burning fossil fuels, factories, vehicles, and household smoke. These are all major causes of air pollution. But there are also some alternative emission scenarios that have been developed that can help in the fight against air pollution.
Human development
Across Africa, ambient air pollution is on the rise. It causes a large loss of economic output and human capital through premature death and disease. It is a major threat to health, and African countries have a key opportunity to develop non-polluting pathways to growth.
African countries have the capacity to reduce pollution through policy. By investing in renewable energy, developing non-polluting technologies, and avoiding the burning of fossil fuels, most countries can avoid the environmental and economic costs of pollution.
Air pollution is responsible for more deaths than tobacco, alcohol, and road accidents combined. It is also associated with long-term health effects, including respiratory diseases and heart disease. It causes long-term damage to nerves and organs.
Air pollution has also been associated with output losses in manufacturing and service industries. It is especially harmful to children. It reduces cognitive function and impairs physical development.
Clean Air scenario
Currently, PM2.5 concentrations in many areas of the world are below the World Health Organization’s recommended guideline value of 10 ug m-3. However, bringing PM2.5 levels to 5 ug m-3 or lower could significantly reduce global air pollution. The Clean Air scenario for the prevention of air pollution proposes a variety of measures to achieve this goal.
The Clean Air scenario provides a glimpse of what could happen if we took a more aggressive approach to improve the quality of air across the globe. It includes policies to enhance the energy efficiency, enhance nitrogen use efficiency, reduce temperature increases, and improve urban air quality. The results show that by 2040, we could be on our way to cutting global pollutants by about 90%.
The Clean Air scenario would significantly improve the health of a large portion of the global population. In particular, it would reduce ambient air pollution to a level that would prevent 3 to 9 million premature deaths annually. It would also reduce CO2, SO2, NOx, VOC, and black carbon emissions by roughly 70%.
Alternative emission scenarios
Identifying alternative emission scenarios for preventing pollution is important for understanding the future impacts of climate change and quality. These scenarios should demonstrate the potential of policy interventions to reduce global pollution and reduce health impacts. These include emission control measures in industry, transport, and agriculture. The benefits of such reductions are not yet quantified but could be substantial.
To determine the best measures for the best results, a cost-benefit analysis is important. This will identify which measures deliver the greatest benefits for the smallest costs. For example, increasing access to clean household fuels and food policies could reduce indoor exposure to PM2.5. Other mitigation measures are conceivable for PM2.5 precursors, such as solvents embedded in cosmetics and cleaning agents.
Household air pollution trends in Africa
Despite rapid urbanization, air pollution is still a major risk to human health in Africa. In fact, it is the second leading cause of death in the continent, after malaria. It is estimated that household pollution accounts for nearly 60% of all pollution-related deaths. In addition to contributing to death, air is a major contributor to disease. It causes chronic lung disease, heart disease, stroke, and drug abuse.
In 2019, household air pollution accounted for 1.1 million deaths in Africa. This was the second-highest number of air pollution-related deaths after malaria and was responsible for more deaths than alcohol.
Air pollution is a major risk to human health, particularly in Africa, which has the largest population of people living in low- and middle-income countries. In fact, air pollution is responsible for more deaths in Africa than alcohol, tobacco, and road accidents combined. It contributes to ischaemic heart disease, chronic obstructive pulmonary disease, and lower respiratory infections. It also has a substantial impact on human capital.
