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.

Students who make use of wheelchairs at the University of the Free State (UFS) will now be able to move around campus more independently than before. This is thanks to two SmartDrive Power Assist devices acquired by the university.

Accessibility is very important to the institution and with these devices clipping onto a manual wheelchair to make it motorised, students will not have to ask for help that often. It will assist them in overcoming obstacles they face every day.

Different surfaces pose different challenges 
According to Martie Miranda, Head of the Center for Universal Access and Disability Support (CUADS), one of the most important advantages of the SmartDrive machines is that it enhances the independence of students. The devices were bought with funds received from the Department of Higher Education and Training specifically allocated for accessibility and infrastructure.
 
“While the UFS is addressing inaccessibility on its campuses, which will take time, this will help to motorise wheelchairs for wheelchair users to move around more easily. Students can now move around independently without necessarily asking for help, for example, to get up very steep ramps.” Miranda says some surfaces, such as grass and gravel, has its own unique challenges for wheelchair users.

A few years coming
The SmartDrive devices are operated by a Bluetooth watch. By tapping twice on the chair or clapping twice, the motor propels the wheelchair forward and stops when tapped twice, while also braking with one’s hands. The speed can also be controlled by the user. The machines use rechargeable batteries, with a fully charged battery lasting up to 15 hours.
 
Acquiring the devices was a process of a few years, and CUADS is happy to finally employ them to the benefit of their students. Miranda says the determination and support of Prof Nicky Morgan, Vice-Rector: Operations, and the assistance of Nico Janse van Rensburg, Senior Director: Top Management, were instrumental in buying the devices.
