Air pollution in Côte d’Ivoire is mainly caused by road traffic and firewood. In Abidjan, vehicles emit pollutants such as NO2 and fine particles, especially during the dry season (November to February). These emissions aggravate respiratory and cardio-respiratory problems. Here are the key solutions to improve air quality:
- Smoothing traffic flow : Reducing traffic jams through suitable infrastructure.
- Develop public transport : Invest in buses and ecological alternatives.
- Monitoring pollution : Using sensors like INDAAF to measure pollutants.
- Regulate emissions : Implement strict policies to limit harmful gases.
With rapid and coordinated action, it is possible to reduce emissions by up to 50% and improve public health.
Factors Affecting Air Quality in Ivory Coast
Vehicle Emissions
Analyses carried out under the DACCIWA WP2 programme have highlighted worrying levels of certain pollutants [2] [3] . The main pollutants emitted by vehicles are:
| Pollutant | Health Effects | Period Concerned |
|---|---|---|
| Nitrogen dioxide (NO2) | Breathing problems | Dry season (November-February) |
| Carbon monoxide | Respiratory toxicity | All year round |
| Fine particles | Cardio-respiratory disorders | Dry season |
Data from INDAAF sensors (December 2014 to April 2017) show a clear correlation between heavy traffic and high NO2 levels, especially in urban areas [2] [3] . During the dry season, low rainfall and stagnant air make the situation worse.
But vehicles are not the only sources of pollution in these areas.
Other Sources of Pollution
Firewood used in homes remains a major source of pollution, particularly in residential areas. Measurements reveal high levels of ammonia (NH3), with marked peaks during the dry season [2] [3] .
Waste burning and industrial emissions add to the pollution, intensifying it. For example, NOx emitted by vehicles interacts with volatile organic compounds to form tropospheric ozone [1] [2] . These reactions show how effective traffic management can reduce the overall impact.
Understanding these complex interactions is essential for adopting modern, coordinated approaches to improving air quality.
Traffic Management Solutions for Better Air Quality
Improved Traffic Flow
Effective traffic management can significantly reduce pollutant emissions in urban areas of Côte d’Ivoire. Here are some technical solutions that have already shown results:
| Solution | Main Impact |
|---|---|
| Optimizing traffic flows | Less emissions and better fluidity |
| Improving infrastructure | Reduction of traffic jams |
These measures must be accompanied by initiatives encouraging more environmentally friendly modes of transport to maximise their efficiency.
Promotion of Public and Ecological Transport
The DACCIWA WP2 project highlights the importance of diversifying transport options [2] [3] . For example, the expansion of the bus network in Abidjan and the creation of dedicated lanes have already shown promising progress. AutoMag.ci , a platform specializing in sustainable mobility in Côte d’Ivoire, is documenting these initiatives and raising awareness of environmentally friendly alternatives.
Implementation of Emission Control Policies
In addition to efforts to smooth traffic flow, strict emission control policies are essential to sustainably improve air quality. NILU ‘s AirQUIS system provides a basis for air quality management [1] , while the INDAAF sensors (2014-2017) highlight the importance of regular pollution monitoring [2] [3] .
Strategic collaborations, including with companies like AUTO24.ci , accelerate the transition to less polluting vehicles and strengthen the impact of environmental policies. This type of partnership helps address the specific challenges related to Abidjan’s rapid urbanization while encouraging more sustainable solutions.

Use of Data and Technology
Emissions Inventories and Urban Models
Modern monitoring and analysis tools play a key role in air quality management in Côte d’Ivoire. For example, data from INDAAF sensors, used in the DACCIWA WP2 programme, are used to feed detailed urban models [2] . These passive sensors are particularly useful for measuring NO2 levels in high-traffic areas, such as in Abidjan.
Thanks to these technologies, it is possible to precisely map the affected areas, simulate the impact of pollutants and monitor their evolution in real time.
| Technological Tool | Main Application | Impact on Air Quality |
|---|---|---|
| Passive sensors | Measuring atmospheric pollutants | Identification of critical areas |
| Pollutant propagation models | Simulation of scenarios | Evaluation of possible interventions |
| Real-time monitoring systems | Continuous monitoring of concentrations | Rapid reactions to variations |
Urban models allow to test different scenarios and assess their effects on air quality. By targeting sensitive areas and simulating solutions, these tools help to better manage traffic-related emissions. Their effectiveness is further enhanced when integrated into advanced management systems, such as AirQUIS.
Integrated Air Quality Systems
AirQUIS combines several functions, including data collection, modeling and graphical visualizations, to provide comprehensive air quality management [1] . For this system to work in Côte d’Ivoire, close collaboration between local authorities and international experts is necessary to adapt the solutions to the specific needs of the country.
The integration of these technologies could transform the management of urban pollution in Côte d’Ivoire, while improving living conditions in the most affected areas.

Conclusion
The study on traffic management and air quality in Côte d’Ivoire highlights major challenges, but also promising opportunities. Figures show that measures such as improving traffic flow and strengthening public transport could reduce emissions by 20% and 50% respectively [1] [2] .
INDAAF sensors have proven valuable in monitoring urban pollution. Progress will require advanced technologies and appropriate policies [2] [3] .
Three main axes are essential to the success of these initiatives:
| Strategic Axis | Key Actions and Expected Results |
|---|---|
| Traffic management | Smoother travel and reduced traffic jams |
| Public transport | Investing in modern and accessible infrastructure |
| Monitoring | Install reliable and accurate measuring tools |
Without timely action, air pollution will continue to harm public health and hamper urban development in Côte d’Ivoire. Close collaboration between local and international experts will be essential to build healthier cities and improve the quality of life for residents.
Modernising traffic, combined with well-thought-out policies, offers a real chance to transform urban spaces and ensure a more breathable future for all.
