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.

When hockey becomes a part of you
2014-06-25

Izelle Lategan, a fourth-year BSocSci (Human Movement Sciences) student at our university, continues to fly the Kovsies’ flag high on national level.

In December 2010, Izelle made her debut for SA hockey against Argentina. Among her greatest achievements wearing our country’s colours, are:

  • she scored a hat trick against India in Ireland in 2012 (SA won that game 3-2), and
  • she was captain of the Junior World Cup U/21 team in Germany this year.

“Representing the country amounts to a lot of pressure. I managed to get through by working hard and putting in extra training hours in order to achieve all these,” she says. “When you have a setback, don’t step back, but rather make a comeback!”

She appreciates the support she receives from her family, friends and coach – especially when on international tours. “Even though they can’t make it to all my games, they try hard to show their support when they can,” she added.

Izelle’s focus is now on representing Kovsies at the South African Student Sports Union (SASSU) games in Pretoria from 30 June – 4 July 2014. She is currently resting from national duty, since she wants to complete her undergraduate studies this year, but aims to return next year.

Her long-term goal is to play at the 2016 Olympics in Brazil.
