 Air pollution is now the world's single largest environmental health risk. It increases the risk of respiratory and heart disease in the general population. Almost 7% of all deaths worldwide are attributable to ambient air pollution, most of which are in low and middle income countries. Major sources of air pollution include industrialisation, motorisation, fuel burning and urbanisation. The rate of urbanisation in Africa is the highest in the world and over 800,000 deaths annually on the continent are due to air pollution. We collected data on meteorological conditions and air pollutant levels and developed a decision support system for air quality management. Our online portal uncovers trends and provides insights on air quality. The computer models we developed can predict the levels of air pollution and we are working towards high-resolution air quality forecasting. The ultimate goal is to safeguard the health and wellbeing of people and the environment.
