Ndumiso Mbuthuma is currently pursuing a PhD in Development Studies with a focus on floods and disasters.

Ndumiso Mbuthuma, a PhD student at the University of the Free State (UFS), was part of a team that won the Durban leg of the Students Reinventing Cities competition. “It was a beautiful experience and an opportunity to not only be a student again but to contribute to the greater good,” Mbuthuma said.

The Students Reinventing Cities competition is coordinated by C40, a global network of nearly 100 mayors of the world’s leading cities who are united in action to confront the climate crisis.

The Umgeni Interchange Team, which consisted of Mbuthuma, who is a student in the UFS Centre for Development Support, three students from the University of Cape Town, and one from an institution in France, participated in the Durban leg of the competition, which began in April 2023. 

After deliberations by C40 and city representatives, the team was informed on 13 July 2023 that they had been selected as the winners of the regional Durban competition.

The Students Reinventing Cities competition provides a platform for students and academics to work with cities around the world to formulate plans to combat climate change. This year the competition took place in 12 cities, including Barcelona, Durban, Rome, Melbourne, and Milan, among others. “The aim of the competition is to find ways in which we can begin to build cities that are climate change-friendly,” Mbuthuma said. 

The winning presentation

The Umgeni Interchange Team was allocated four hectares of land by the eThekwini municipality to come up with a development idea. The team members, who specialise in various fields, had to rely on each other to create a winning project. Their proposal entailed the development of a mixed-use, commercial, retail, and affordable-housing block. 

“We wanted to ensure affordable housing not just for the rich but even for those who aren’t,” Mbuthuma explained. His PhD, which focuses on floods and disasters, provided guidance on ensuring that the housing block was resistant to floods and other disasters. The proposal also suggested sustainable resource use, including the use of solar panels to generate energy in order to reduce the impact of loadshedding. 

Even though a victory in the competition is a great feeling, Mbuthuma is more appreciative of the opportunity to have been active in the battle for a more sustainable future. “To hear that policymakers are interested in hearing what I have to say is a big deal to me.”

Future endeavours

Although there has been a concerted effort globally to combat climate change, Mbuthuma believes that in countries such as South Africa there hasn’t been adequate discourse around how development will take place in a future defined by climate change and the resulting disasters expected. As such, he is committed to working towards normalising these conversations.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
