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.

South Africa hosts some of the world’s largest telescopes, and won the bid to co-host the SKA recently. So it’s not surprising that there is unprecedented interest in Astronomy in our country. Astronomy is seen as a gateway subject that attracts people to the sciences, while planetariums help to make Astronomy accessible to millions of people.  Digital planetariums are especially powerful teaching tools because they are versatile, offer an immersive experience, and explain and illustrate three-dimensional concepts effectively.  On the other hand, scientists, are eager to exploit a digital planetarium’s potential to represent and explore data visually, whether the data relate to medicine, astronomy, chemistry, the environment, or other fields of research.

The four-day ‘Digital Sky Academy’ (DSA) presented at the Naval Hill Planetarium in Bloemfontein from 18 - 22 September 2015 was an opportunity to offer training and first-hand experience of digital planetarium technology to representatives from other centres in South Africa. The Department of Physics at the University of the Free State (UFS) was the host of this event.

The Department of Science and Technology has designated the Naval Hill Planetarium as the South African hub for the training of digital planetarium presenters and operators. In addition to attracting interest from scientists and future planetarium operators and presenters, the DSA workshop provided an invaluable opportunity for our presenters to hone their skills.

A number of experienced and distinguished people attended the workshop. Among them was Dr Mark SubbaRao from Chicago in the United States, who shared information on data visualisation techniques used in the Adler Planetarium. Jack White, Director of Sky-Skan, one of the few companies that provide digital technology for planetariums throughout the world, coordinated the event in partnership with Prof Matie Hoffman from the Department of Physics at the UFS.

Jack travelled from Melbourne in Australia to oversee the workshop. Two Sky-Skan colleagues from the United States, Martin Weiss and Martin Ratcliffe, were on hand to share their expertise on digital planetarium hardware and software. The workshop programme included Skype conference calls with other US-based planetarium experts. Amongst the delegates to the DSA representatives from the SKA, the Iziko Museum, and five South Africa universities. They were here to gain experience, explore the capacity of the digital facility, and share ideas on future collaboration.

During the workshop, a public lecture was held on 19 September. Dr Michelle Cluver from the University of the Western Cape gave a presentation entitled, ‘More than the eye can see: the significance of infrared light in Astronomy.’
