Air Pollution

in Chad

What national significance does it have?

2

Firstly, in Chad, air pollution is a serious environmental issue. According to the most recent data, the composition of waste (plastics, used tires, and other organic and inorganic materials), combined with the widespread practice of unrestricted waste burning, makes waste a source of emissions that vitally harm human health, such as dioxins and furans. Important air quality challenges related to transportation, such as the number of vehicles, an aging fleet, dirty fuel, inadequate public transportation, etc.

Secondly, 90% of the energy used in Chad comes from wood and charcoal, but the country is also using more natural gas, with consumption rising. Only 2% of households use electricity, and only 12% of households in the capital and 1% of households in rural areas have access to it. Indoor air pollution is thought to be responsible for 9,600 premature deaths annually.

Lastly, Chadian dust storms are thought to be a significant factor in the alteration of some terrestrial and marine ecosystems as well as a potential major source of pathogens and contaminants. The Bodele Depression in Chad contributes roughly half of the 40 million metric tonnes of dust that are blown across the Atlantic every year from the Sahara to the Amazon.

What are some possible solutions to the problem?

Chad's Ministry of Environment, Water, and Fishing is collaborating with the Supporting National Planning (SNAP) Initiative to create an integrated greenhouse gas, short-lived climate pollutants, and air pollution inventory. This initiative will strengthen the country's capacity to handle challenges connected to mitigating short-lived climate pollutants and clear the way for informed emission reduction policies to yield in-country benefits for health and economic prosperity.

What can your audience do to help?

Model of air quality in Chad

The audience could help by:

  • reduce usage of vehicles
  • don't burn garbage
  • plant and care for trees
  • use less energy
  • creating awareness among others
  • take public transport

There are absolutely more ways that the audience could definitely help. Why wouldn't you? Air pollution is obviously important to everyone and it effects mostly every single person in the world.

The Data Integration Model for Air Quality (DIMAQ) uses ground measurements, satellite data, and chemical transport models to estimate annual exposures of PM2.5 levels globally. It provides high spatial resolution estimates for all regions, including areas without PM2.5 monitoring. The model calibrates data from various sources with ground measurements.

What will the consequences be if action is not taken?

What is the nature of air pollution?

The consequences if action is not undoubtedly taken would be major impacts on our health and the environment.

Air pollution has a significant influence on our health, lowering our quality of life and shortening our lives. In fact, it is the world's single greatest environmental health concern. It aggravates respiratory issues and increases the likelihood of asthma episodes, resulting in additional hospitalisations. Prolonged exposure can lead to major health problems such as cancer, heart attacks, and strokes. In reality, air pollution is responsible for one in every three fatalities from strokes, lung cancer, and chronic respiratory illness worldwide.

However, while we are all affected, those who are most vulnerable in our society, particularly children and the elderly, are at greater danger. Children who are exposed to air pollution may develop respiratory problems and have their lungs stunted.

To conclude, many of the causes of air pollution are also sources of greenhouse gas (GHG) emissions. Greenhouse gases store the Earth's heat in the atmosphere, causing greater temperatures and aggravating climate change. Air pollution may also have an influence on soil and water quality, affecting ecosystems and wildlife.

Chemicals or other airborne particles that are harmful to plants, animals, and people collectively constitute air pollution. Buildings are also harmed by it. The various types of air pollution, they could be gases, spheres of solid matter, or droplets of liquid.

Chad Worst Among Countries

This video tells us how pollution is extremely effected in Chad and surveyed people who live there that shows who is effected by the air pollution.
