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.

Prof Habib addresses inequality at public lecture
2014-08-06

 
One of South Africa’s leading political commentators, Prof Adam Habib, gave a public lecture and launched his latest book on the Bloemfontein Campus on Wednesday 30 July 2014. The event was hosted by the Department of Philosophy in association with Wits University Press and The Southern African Trust.

Prof Habib started his lecture by summarising his book, ‘South Africa’s Suspended Revolution: Hopes and Prospects’. “It is basically about: how did we get where we are today, and how do we get out of the mess we are in?” he said.

His book focuses on South Africa’s transition into democracy and the country’s prospects for inclusive development – which formed the basis of his talk. Prof Habib stressed the issue of inequality facing South Africa and discussed the different approaches to addressing the matter.

“The one approach is that it is simply something we have to live with,” he said. “People who believe this live in a bubble. For example, service delivery protests do not happen because of poverty – it happens because of inequality.”

Prof Habib cautioned against not taking the matter seriously. “Inequality went up consistently in South Africa over the last 20 years. This is however not solely a national challenge, but a global challenge. And South Africa is the frontline of the war on inequality.”

He proposed that the expectations of the rich, rather than the poor, should be addressed.
“We need to moderate expectations. But we can’t moderate the expectations of the poor, if not the rich. We can’t ask the poor to sacrifice what the rich won’t.

“South Africa is once again at a moment of reckoning, where we are forced to make hard choices – in order to make the right choices.”
