David Shikoyeni received a master’s degree in Town and Regional Planning during the UFS December Graduation Ceremonies. He was inspired to study at the UFS after he experienced the competency of UFS graduates he worked with.

Amid hardship and difficulty, David Shikoyeni received his master’s degree in Town and Regional Planning. It was awarded to him at the December Graduation Ceremony of the Faculty of Natural and Agricultural Sciences on the Bloemfontein Campus of the University of the Free State (UFS) on 11 December 2019. 

Shikoyeni, who completed his undergraduate studies at the Namibia University of Science and Technology, had the opportunity to work with several town planners who graduated from the UFS. He was inspired by their competence, which motivated him to apply for his postgraduate studies at the UFS Department of Urban and Regional Planning.

At the time (2013) when he applied for an Honours Degree in Town and Regional Planning, Shikoyeni was working for the Walvis Bay Municipality in Namibia.

Persisting and the will to overcome

He describes the start of his UFS journey: “After a 26-hour bus ride, I arrived at the UFS for the first contact session of my honours studies. It was expensive, since I did not secure any study loans or bursaries and I had to stay in a hotel for the duration of the block classes.”

He continues: “And studying was boring since I did not study for a while. The pressure of school, work, and family life was too much to handle.”

Shikoyeni, however, believed in himself and knew that he had a goal to achieve. Seeing what he was capable of, Shikoyeni persisted and proceeded to a master’s in Town and Regional Planning. 

The impact of mining on small towns

In addition to his recent qualification, Shikoyeni believes that the UFS has equipped him with research skills. For his master’s dissertation he researched the topic: The impact of mining on the land use and planning of a small town: the case of Karibib, Erongo Region, Namibia.

Shikoyeni explains: “Mining has both positive and negative effects on land use as well as on the development of most of the small towns.”

The study was conducted in Karibib due to the town’s rich mineral resources. The area is dominated by mining activities, including gold, lithium, and marble. Development is largely dependent on the mining staff and the mines’ land use demand. As a result of consistency of the gold price and the newly opened lithium mine, the population in the area is still increasing. 

Shikoyeni found that although there are employment opportunities in Karibib, people are faced with challenges regarding property values, employment opportunities, economic growth, unaffordable housing, an increase in informal housing, and pressure on existing services.

Contributors to Shikoyeni’s study indicate that mining regions are undergoing land-use change processes that are different from what might have been expected in the absence of high-quality mineral deposits and, as such, they should be managed differently. Knowing how to do this requires a general understanding of land-use change processes that occur in these regions. 

“To prevent another ghost town, Karibib must be attractive to investors. It needs industries to generate income, transport services, trade, educational facilities, and health services. 

Shikoyeni states that most of these requirements are provided partially or entirely by local providers. “This is the role that diversification plays. Local authorities should not prescribe but encourage investors to take up such activities. They should promote all attempts to ‘go local’.

“If the government, be it at local or regional level, cannot encourage the growth of a tax-paying population, it has failed in its purpose,” Shikoyeni concludes.

In August 2017, the Boyden Observatory in Bloemfontein played a major role in obtaining optical observations of one of the biggest discoveries ever made in astrophysics: the detection of an electromagnetic counterpart to a gravitational wave event.
 
An article reporting on this discovery will appear in the prestigious science journal, Nature, in October 2017. Co-authors of the article, Dr Brian van Soelen and Hélène Szegedi, are from the Department of Physics at the University of the Free State (UFS). Both Dr Van Soelen and Szegedi are researching multi-wavelength astronomy.
 
Discovery is the beginning of a new epoch in astronomy
 
Dr van Soelen said: “These observations and this discovery are the beginning of a new epoch in astronomy. We are now able to not only undertake multi-wavelength observations over the whole electromagnetic spectrum (radio up to gamma-rays) but have now been able to observe the same source in both electromagnetic and gravitational waves.”
 
Until recently it was only possible to observe the universe using light obtained from astronomical sources. This all changed in February 2016 when LIGO (Laser Interferometer Gravitational-Wave Observatory) stated that for the first time they had detected gravitational waves on 14 September 2015 from the merger of two black holes. Since then, LIGO has announced the detection of two more such mergers. A fourth was just reported (27 September 2017), which was the first detected by both LIGO and Virgo. However, despite the huge amount of energy released in these processes, none of this is detectable as radiation in any part of the electromagnetic spectrum. Since the first LIGO detection astronomers have been searching for possible electromagnetic counterparts to gravitational wave detections. 
 
Large international collaboration of astronomers rushed to observe source
 
On 17 August 2017 LIGO and Virgo detected the first ever gravitational waves resulting from the merger of two neutron stars. Neutron star mergers produce massive explosions called kilonovae which will produce a specific electromagnetic signature. After the detection of the gravitational wave, telescopes around the world started searching for the optical counterpart, and it was discovered to be located in an elliptical galaxy, NGC4993, 130 million light years away. A large international collaboration of astronomers, including Dr Van Soelen and Szegedi, rushed to observe this source.
 
At the Boyden Observatory, Dr Van Soelen and Szegedi used the Boyden 1.5-m optical telescope to observe the source in the early evening, from 18 to 21 August. The observations obtained at Boyden Observatory, combined with observations from telescopes in Chile and Hawaii, confirmed that this was the first-ever detection of an electromagnetic counterpart to a gravitational wave event. Combined with the detection of gamma-rays with the Fermi-LAT telescope, this also confirms that neutron star mergers are responsible for short gamma-ray bursts.  
 
The results from these optical observations are reported in A kilonova as the electromagnetic counterpart to a gravitational-wave source published in Nature in October 2017.
 
“Our paper is one of a few that will be submitted by different groups that will report on this discovery, including a large LIGO-Virgo paper summarising all observations. The main results from our paper were obtained through the New Technology Telescope, the GROND system, and the Pan-STARRS system. The Boyden observations helped to obtain extra observations during the first 72 hours which showed that the light of the source decreased much quicker than was expected for supernova, classifying this source as a kilonova,” Dr Van Soelen said.
