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.

“Our education system needs quality teacher education.”

This was the message from Prof Jean Baxen, Deputy Dean of Research at Rhodes University in Grahamstown. She delivered the Education Public Lecture on ‘The lives of children, citizenship and teacher education: challenges and opportunities’ at the University of the Free State’s Bloemfontein Campus.

Growing up in White River, the rural areas of Eastern Transvaal (as it was previously known), Prof Baxen took the audience on a journey of the imagination. She shared stories of how she and fellow learners walked miles to get to school and how her son found himself in a situation of being unsure about his own racial identity, questioning what it meant to be ‘coloured’. She also related stories of how teachers are not sufficiently prepared to mediate information on HIV/Aids.

These stories revealed how little teachers cared, and also how difficult and challenging it is for learners to cope in such teaching and learning environments – thus calling for quality teacher education.

She stressed the fact that quality teacher education is needed in South Africa to assist in curbing the challenges children and fellow citizens come across in our broader society. “It is important that, as teacher educators, we should groom teachers to find and understand their identity, sexuality, and also the world they live in. There is an urgent need for us to hold ourselves and others accountable and to not distance ourselves and make it someone else’s responsibility – it is our joint responsibility as citizens,” she said.

We need a pedagogy that would navigate and start formulating a language that we could use to face these challenges, she proposed.
