Dr Kgosi Mocwagae explored the Qwaqwa water crisis because at a young age, he could not understand why the community in which he grew up faced so many water challenges despite a high presence of water from rivers, consistent rainfall, and streams bursting from the ground.

Dr Kgosi Mocwagae, Programme Director and Lecturer: Department of Urban and Regional Planning, received his PhD qualification during the October virtual graduation ceremonies.

His study, titled Exploring the Qwaqwa water crisis for effective planning post-apartheid, focuses on the water crisis in the Qwaqwa area, which commenced on 1 January 2016 and saw people without access to clean drinking water from their taps. The community had to turn to alternative means, such as collecting water from government-contracted water tankers, rivers, emergency hydrants, and wells.

Understanding the water crisis

Dr Mocwagae says the reason why he took up this study was because at a young age, he could not understand why the community in which he grew up faced so many water challenges despite a high presence of water from rivers, consistent rainfall, and streams bursting from the ground.
 
In this study, he aimed to explore the history of water policy in South Africa, together with the water crisis in Qwaqwa. He also documented the lived experiences of the affected Qwaqwa communities to determine the effect of not having access to clean drinking water in terms of quality of water, time, money, and distance travelled, to name just a few. 

Dr Mocwagae furthermore assessed interventions by various actors during the Qwaqwa water crisis, which included accessing water from municipally contracted water tankers, streams and rivers, rainwater harvesting, donations, paying for delivery of water, boreholes, and emergency water hydrants intended for fire breakouts. He also investigated the implications of the Qwaqwa water crisis for effective planning in post-apartheid South Africa.

He states: “Despite reports from the government that the Qwaqwa water crisis was an issue from 2015 and a result of drought, the study proved differently.” 

Water crisis due to poor planning

“Firstly, the water crisis was a cumulative effect of poor water planning since the founding of Qwaqwa as a homeland in 1974. Further to this, Qwaqwa has not been able to sufficiently provide water to the community from 1974 to date.”

Dr Mocwagae continues: “A major contributing factor to the water crisis was that the three dams in the area were still performing their primary functions as established during apartheid. Planning would have to be done to reprioritise water to Qwaqwa.

He also found that the municipality had not planned and invested in the maintenance and development of water infrastructure to provide water. 

The study was also able to demonstrate that there is a form of socialisation in planning that does not prioritise the community of Qwaqwa. In this community, more than 50% of the people live in poverty. According to Dr Mocwagae’s findings, the idea exists that the community first needs to be viewed a worthy economic contributor in order for them to benefit from water that originates from Qwaqwa. 

“Alternative means of accessing water and water-use education are also needed as part of the process of resolving the Qwaqwa water crisis,” says Dr Mocwagae.

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.
