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.

MSc student plans to FEED our hungry planet

Since attending the 2014 Youth Ag-Summit in Canada, Lisa Coetzee – an MSc student in Plant Pathology in the Department of Plant Sciences at our university – developed a plan to address hunger:

FEED – Forum of Education, Empowerment and Development.

Coetzee, together with a junior lecturer at Plant Sciences, Marguerite Westcott, started this student association to tackle the issue of food insecurity head-on.

Education, empowerment and development “are keywords vital to the solutions to poverty. Hunger is an issue which is found in our own homes. One in every four South Africans is food insecure. Hunger kills more people every year than Aids, malaria and TB combined,” says Coetzee.

“This forum allows awareness to be raised about the hunger situation locally and globally. FEED is talking about hunger and it is assisting in reducing it by reaching out to communities which are in need.

“FEED is the generation which is going to make a difference in eradicating hunger,” Coetzee continues. “We want students to think about how they can feed the hungry through what they are studying”. For Coetzee it is a high priority to ensure that the youth are aware of the importance to feed our hungry planet in a sustainable way.

Her philosophy on relieving hunger and increasing food safety is to enhance the efficiency of crop production, ensure crop security and reduce mycotoxins in the food we eat.

During the 2014 summit, Coetzee was elected to represent the African delegates on the Youth Ag Summit Committee. Ever since, she has been enthusiastically active in the agricultural community. As 43% of the globe’s farmers are women, Coetzee also feels she acts as a voice for female farmers in South Africa.

An important lesson Coetzee has learned is that there is power in one person to make a change – that we should start small but think big.
