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.

Dr Dirk Strydom, a member of the Vice-Chancellor’s Prestige Scholars Programme (PSP) at the University of the Free State (UFS), was presented with the title of 2015 Free State Agriculturist of the Year.

Dr Strydom, head of the Department of Agricultural Economics, received the award on 23 October 2015 from the Agricultural Writers Central Region, the professional association promoting the image and standards of agricultural journalism in South Africa.

“A driven and ambitious young academic,” is how Dr Strydom is described.

According to the Agricultural Writers, Dr Strydom is blessed with the rare skill of bringing to his engagement with the agricultural community at large the same excitement and focus with which he approaches his students and his research.

“Strydom has perfected the art of disseminating complicated theory, and the intricacies of the South African Futures Exchange to the agricultural community.”

Dr Strydom epitomises the new generation of young scholars emerging from the PSP. This new breed of academic is very aware of the need to translate published scholarly discourse into practical usefulness for the broader public.

Hence Dr Strydom’s emphasis on the duty of the scholar to share vital innovation, intricate research, and its applications, not only with students but with the community at large.

The award is recognition for Dr Strydom’s work by the agricultural community.

He was also the recent recipient of an award from the Brahman breeders for his “outstanding scientific contribution” to their industry.
