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.

Snow on our campuses
2012-08-07

Qwaqwa Campus
7 August 2012

Kovsies have been treated to the rather unusual sight of snow Tuesday, with the Qwaqwa Campus covered in a blanket of snow and the Bloemfontein Campus also dusted in white.

Snowflakes on the Bloemfontein Campus had people clicking away on their cameras and cellphones to capture this rare picture. The last time the City of Roses experienced this much snow was about six years ago.

Prof. Sue Walker, Head of Agricultural Meteorology in our Department of Soil, Crop & Climate Sciences, says the snowy weather over the Free State was caused by a cut-off low pressure system in association with a strong anticyclone ridging in behind the cold front.

“This draws a pool of very cold air, in the upper air, from the far southern ocean area in Antarctica driven by a strong southerly wind. This caused the freezing level, which is normally high in the atmosphere, to be lowered to the ground surface level, resulting in the snow.”

Prof. Walker says a little snow is forecast for Wednesday although rain can be expected before it clears and becomes sunny for the long weekend.
