Unique PhD Journeys

On the right is Dr Maréve Biljohn, who as a student has always shown commitment to do her best in every aspect of her PhD journey.

In nature, one often comes across cool and surreal phenomena. Experiencing rare happenings in the academia is an altogether different encounter. One that Prof Liezel Lues, Professor in the Department of Public Administration and Management at the University of the Free State (UFS), explains as winning the lottery.

Two of Prof Lues’ doctoral students – representing two different institutions – graduated in 2018. Four years later, on the exact same date, 1 March 2022, Drs Maréve Biljohn and Modeni Sibanda will take up their new positions, respectively as Head of the Department of Public Administration and Management at the UFS and Head of the Department of Public Administration at the University of Fort Hare.

 

Social innovation and service delivery

Dr Biljohn, currently Senior Lecturer in the department, did her thesis on the topic: Social innovation and service delivery by local government: a comparative perspective. With work experience in local government, Dr Biljohn had a good idea of the problems that underpin poor service delivery in this sphere of government.

Public participation in integrated development planning: a case study of Buffalo City Metropolitan Municipality, was the title of Dr Sibanda’s thesis. The study revealed how individuals and communities navigate forms of power and raise the critical consciousness of municipal residents, communities, and public officials.

According to Dr Sibanda, his study was motivated by the need to explore how public participation power dynamics influence Integrated Development Planning outcomes.

He believes by doing so, the complexity of how individuals and communities navigate forms of power in public participation platforms and spaces would be unravelled. Unravelling such public participation power dynamics, he says, would raise critical consciousness and address and challenge visible, hidden, and invisible forms of power on these public platforms and spaces. “Often public participation platforms and spaces neglect and ignore the capacity of such spaces to manage the pervasive, complex power dynamics among stakeholders in municipal strategic development planning processes. This focus to my PhD therefore sought to fill that knowledge gap,” adds Dr Sibanda.

Prof Lues says the value link to their research is buoyed in the South African Local Government. “They have both established a niche area that addresses the challenges South African municipalities face,” she adds.


“There is no doubt that they are suitable for the position of head of department at this point.”


Achieving a coveted status in their careers

On experiencing this unique journey, Prof Lues says: “Of all the relations, a relation between a promoter and a student is the most inspiring and admirable one. Any promoter takes the utmost pride when his/her taught students achieve coveted status in their respective careers. To me, it feels like winning the lottery – twice.”

UFS research could light up South African homes
2016-01-21

Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology, is using her research to provide solutions to the energy crises in South Africa.

A young researcher at the university is searching for the solution to South Africa’s energy and electricity problems from a rather unlikely source: cow dung.

“Cow dung could help us power South Africa,” explains Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology.

Reitumetse’s research is trying to understand how the bacteria works that is responsible for producing biogas.

“Biogas can be used for cooking, heating, lighting and powering generators and turbines to make electricity. The remaining liquid effluent can fertilise crops, as it is high in nitrogen, phosphorus and potassium.”

By using cow dung and food waste to produce biogas, we will be able to lower greenhouse gases.

Biogas is produced in a digester - an oxygen-free space in which bacteria break down or digest organic material fed into the system. This process naturally produces biogas, which is mainly a mixture of methane and carbon dioxide.

“Many countries, such as Germany and the United States, have begun generating electricity from cow dung and food waste, through a process known as biogas production. In South Africa, a number of industries, including waste-water treatment facilities and farms, have caught on to this technology, using it to generate heat and to power machines.”

Until recently the world has relied heavily on electricity derived from fossil fuels such as coal, natural gas and oil. Once these fuels have been extracted from underground reservoirs, they are treated or cleaned, transported to power plants and transformed into the electricity that will reach your house. Fossil fuels are considered a ‘dirty’ energy source which gives off greenhouse gases when burned. Those gases are the major contributing factor to climate change.

“We know very little about the interaction of the bacteria inside the biogas digester. To use biogas as a sustainable fuel source, we need to understand and describe the bacteria population and growth dynamics inside the digester to produce biogas optimally. Currently we are testing a variety of feedstock, including bran, maize and molasses, for biogas production potential, as well as optimising the conditions leading to maximum biogas production. We are also exploring the potential to use the effluent as fertiliser on local farms. The ultimate goal is to have biogas systems that will supply our university with clean energy.”
