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.

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
