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.

UFS partners with the Steve Biko Foundation
2010-09-14

The Steve Biko Foundation, with the support of the University of the Free State (UFS) and other stakeholders, recently presented the Annual Steve Biko Memorial Lecture as part of the 33rd Anniversary Commemoration of Steve Biko at the University of Cape Town. The lecture, Coming to See You Since I was Five Years Old: An American poet's connection to the South African soul, was delivered by Pulitzer Prize winner Prof. Alice Walker. She drew on her poetry, personal history and the inspirational role of the South African liberation struggle to disenfranchised people around the world.

This prestigious lecture has to date been delivered by, amongst others, such luminaries as former presidents Nelson Mandela and Thabo Mbeki, Archbishop Desmond Tutu and Prof. Chinua Achebe. The lecture was preceded by an evening of poetry and prose, An evening with Alice Walker, at the State Theatre in Pretoria where the UFS was also represented. Pictured at the lecture are the UFS representatives, from the left: Mr Teboho Manchu (Director: Student Affairs, Qwaqwa Campus), Mr Willem Ellis (Centre for Development Support), Ms Lihlomelo Toyana (student), Mr JC van der Merwe (Department of Philosophy) and Mr Billyboy Ramahlele (Director: Community Engagement).
