Air pollution not only costs lives, it costs money too. Pictured is Prof Cathryn Tonne presenting a guest lecture on air pollution at the Bloemfontein Campus.

Health effects associated with ambient air pollution (AAP) have been well documented. Subsequently, the relationship between pollution and financial outcomes have also become a focus for case studies globally. An Environmental Research journal article revealed that “low and middle-income countries are disproportionately affected by the global burden of adverse health effects caused by AAP”. 

A high price to pay

In 2012, high concentrations of air pollution caused 7.4% of all deaths, costing South Africa up to 6% of its Gross Domestic Product. According to the recent International Growth Centre study conducted by senior University of Cape Town researchers, this is a direct consequence of the country’s heavy dependence of fossil fuels, a source of health-damaging air pollution and greenhouse pollutants.

Stunted human and economic growth

These South African statistics are attested to by Prof Cathryn Tonne who recently presented a guest lecture on air pollution which was hosted by the University of the Free State (UFS) Business School.

“Air pollution can affect economic development through several pathways, and health is an important one. Air pollution is linked to shorter life expectancy, chronic disease, asthma exacerbation and many other health outcomes that result in absenteeism from work and school. These have large direct costs to the health system.” 

Prof Tonne says that air pollution exposure in children is linked to reduced cognitive development, with important impacts on human capital. As a result, children are not reaching their full potential in terms of neurodevelopment, which has an effect on their income prospects and the economy as a whole. 

Resolving a looming disaster

Technology may be employed to radically clean the air. Cities need to lead in the reduction of air pollution by promoting renewable energy, using active transport such as walking or cycling, and investing in infrastructure to make this safe and attractive. 

With researchers playing a major role in strengthening the case for aggressive air pollution control, the government needs to implement policies in order to control sources of air pollution. This global health and economic issue also requires individuals and communities to play their part to improve air quality.

Because you can do the undoable
2014-05-30


Gabriela Schroder

Since visiting the University of Vermont in 2011 as an F1 student and attending the Stanford Sophomore College the year after, Gabriela Schroder has never stopped dreaming and working towards her objectives.

During the autumn graduation earlier in 2014, Gabriela received the Dean’s Medal. This award goes to the final-year student who achieves the best results in respect of a first Bachelor’s degree in the Faculty of Natural and Agricultural Sciences. Her triumph did not end there. In addition, she also received the Senate’s Medal and Prize which is awarded to the best Bachelor’s degree student at the university. Across all the faculties of our university. 

“Although these medals came to me as a surprise, it really was a reward to my hard work and toil throughout my undergraduate years,” she said. Schroder was also honoured and introduced by Prof Jonathan Jansen on stage at this year’s Kovsie Open Day, along with other top achieving students. She believes that anybody can reach their goals if they are willing to make sacrifices and through focus, hard work and determination. 

One of her favourite quotes that motives her is of Albert Einstein, “You really understand something if you can explain it to your grandmother.” In the process of learning, one must break down what they are working towards. She advises to make the knowledge your own – this develops a better insight into the concept. In the end, that which is regarded as complex is originally built from simple principles.

Schroder is currently studying towards her BSc Honours in Biochemistry at Kovsies. She has her sights set on a master’s degree in the near future.

“To my fellow Kovsies and beyond: seize your opportunities. Don’t be afraid to think the unthinkable – because you can do the undoable,” she added.
