In his book, The World is Flat, Thomas Friedman mentions how at first countries, then companies, and eventually communities went global. In true flat-world fashion, a combined team of the University of the Free State (UFS) and the Astronomical Society of South Africa – led by Prof Matie Hoffman, Associate Professor in the Department of Physics – participated in a once-in-a-lifetime event with their counterparts from the Ellinogermaniki Agogi School and the Skinakas Observatory in Greece.

On 21 December 2020, Earth was treated to the Jupiter-Saturn conjunction, when the two planets were only 0.1 degrees apart in the sky. Although conjunctions are regular phenomena, NASA mentions that the great conjunction of Jupiter and Saturn in 2020 was the closest since 1623 and the closest observable since 1226! A pinkie finger at arm’s length could cover both planets – although they were still millions of kilometres apart in space.

Planning started months ahead of the event, with the Ellinogermaniki Agogi Observatory in Greece and the Boyden Observatory in Bloemfontein chosen as the two selected vantage points. From both the Southern and Northern Hemisphere, the conjunction would be broadcast live on YouTube. As with any other technical project on an international scale, challenges arose. For example, in the Northern Hemisphere, it was already dark at 17:45 while the South African astronomers were still basking in sunlight until after 19:00. The conjunction would only be visible from South Africa after 19:30, almost two hours after it would be visible in Athens. The time was well used, with the event including a word of welcome by the Consul General of Greece in South Africa, Ioannis Chatzantonakis, presentations on Saturn and Jupiter, as well as a virtual tour of the Boyden Observatory, emphasising its connection with Greece through its first Director, Stefanos Paraskevopoulos. 

On Saturday, 19 December, the teams ‘gathered’ on opposite sides of planet Earth to do a dry run. One could sense the urgency and tension as both teams realised that they would have a huge captive audience on YouTube, and plans had to be made in case of connectivity challenges and if the weather did not allow the conjunction. As preparations progressed, Prof Hoffman was talking to his Greek counterparts and was simultaneously walking around with his laptop to share the landscape and activities via his webcam with colleagues in Greece. 

Monday 21 December 2020 – the weather prediction was correct. Clouds covered the Free State sky and scattered raindrops started to fall. Revert to Plan B. A recording made on Saturday evening was shared via the YouTube link, while a live feed of the conjunction from elsewhere in South Africa was arranged. From both sides of the world, information was shared about the history of the venues, as well as the marvel of what was happening in space. Fortunately, expert planetary photographer Clyde Foster was able to share a live feed just after 19:30 from the observatory at his home in Centurion, Gauteng. Those attending the event where visuals and speakers were together on one screen – yet thousands of kilometres apart – watching an event in outer space, will indeed agree with Thomas Friedman: the world is flat. The live-stream event of the conjunction was a catalyst that will result in continued collaboration between the UFS and colleagues in Greece in the field of astronomy. 

By the time of this writing, the livestream has reached more than 50 000 people.

As part of celebrating 20 years of existence, the Centre for Environmental Management at the University of the Free State (UFS) hosted a public lecture themed, ‘The Future of Environmental Management’. Mr Tshepo Moremi, Deputy Director-General of the Department of Environmental Affairs and Tourism (Free State), portfolio Environment, Conservation and Tourism, delivered this lecture.

Mr Moremi said, “The environmental performance of South Africa must be seen in the context of our history and the country’s transition. South Africa has taken the lead in being a responsible global citizen, and we also participate in international projects in this field.”

South Africa hosts one of the richest biodiversities in the world. However, the country’s economy is still very energy - and carbon intensive.

“According to the World Health Organisation, approximately 16% of all deaths and one-third of diseases in children under the age of five years are environmentally related. Inadequate sanitation and indoor pollution are key factors,” Mr Moremi said.

“Academic institutions like the UFS and the government need to take the role of equipping citizens with skills and training so that we can overcome the challenges and seize opportunities related to the environment.

“Financing mechanisms for projects related to environmental sustainability were introduced in 2011. However, we still lack skilled capacity to run these projects smoothly and to use international and national funding strategically.

“Looking forward and responding to our challenges, it is vital that we transform our economy to be an international competitor and job-creation hub, and to be sustainably climate resilient, as outlined by the National Development Plan. Minimum standards will also be put in place to regulate emissions and monitor air quality. The sustainability of society’s well-being is important to the long-term role of environmental management in boosting our socio-economic status as a nation,” Mr Moremi said.

He emphasised that it must not only be about conserving and preserving. “Our people should benefit economically and socially,” he said.

Mr Moremi encouraged the audience to defend ideas that protect our non-speaking natural resources. “Let’s all do what we can and rise to this advocacy challenge,” he added. He also expressed his gratitude towards the university for honouring him during such a celebration and for working together in advocating for environmental issues.

The Centre for Environmental Management also hosted a strategic colloquium, discussing issues such as demography, resources, climate, water, environmental management, academic pursuance, as well as curriculum and the role of professional registration which may have an influence on the nature of its programmes.
