With coalition governments becoming more common in South Africa and proven to be unstable, a lecturer at the University of the Free State (UFS) devised an alternative contextual coalition-led framework towards a functioning political-administrative dichotomy. This instability adversely affects service delivery. 

The framework was devised by Dr Ambrosé du Plessis, lecturer in the UFS Department of Public Administration and Management, as part of his PhD research and focused on the City of Johannesburg Metropolitan Municipality. He hopes it can offer valuable lessons for the broader context of South Africa’s evolving political landscape, particularly in light of the 2024 national coalition-led Government of national Unity (GNU). 

Dr Du Plessis graduated with a Doctor of Philosophy with specialisation in Public Administration and management at the UFS April graduation ceremonies. Prof Liezel Lues, Professor of Public Administration and Management, in the Department of Public Administration and Management, was his supervisor. 

Dr Du Plessis is part of the newest cohort of the Emerging Scholar Accelerator (ESAP) mentoring programme for mostly lecturers who are less than five years post-PhD. This group falls within the Transformation of the Professoriate Mentoring Programme which aims to grow a critical mass of excellent emerging scholars at the university who are equipped to assume senior academic and research positions. 

 

Political-administrative dichotomy

With his thesis titled ‘The Political-Administrative Dichotomy in coalition-led metropolitan municipalities: A South African Perspective’, he focuses on the interface between politics and administration. Says Dr Du Plessis: “The political-administrative dichotomy discourse is unable to account for coalition politics in most of South Africa’s metropolitan municipalities. More importantly, political and administrative instability has become common in most of South Africa’s coalition-led metropolitan municipalities.

“What makes my research particularly interesting is that it transcends Public Administration by incorporating contributions from Political Science through critical discourse analysis. I also conducted interviews with political office-bearers, the South African Local Government Association in Gauteng province, as well as subject experts – both national and international – in public administration, political science, and constitutionalism, to uncover deeper nuances relating to local lived experiences and international perspectives,” says Dr Du Plessis. 

According to him, the increasing prevalence of coalition-led governments in South Africa’s metropolitan municipalities necessitates a reconceptualisation of the political-administrative interface. Traditional interpretations of the political-administrative dichotomy have proved inadequate in explaining the multifaceted and dynamic interactions characteristic of contemporary coalition governance. This study responds to that gap by proposing a nuanced, context-sensitive, and theoretically enriched framework that better reflects the realities of coalition-led metropolitan municipal governance in the South African context.

 

The findings of the research 

“Building on comparative and critical discourse analyses, this research advances a polychotomous framework – one that transcends mono-theoretical and discipline-bound approaches by integrating insights from Public Administration and Political Science. The framework acknowledges the existence of both formal and informal political-administrative relationships and interrogates how these configurations influence governance outcomes in coalition-led municipalities, with specific reference to the City of Johannesburg (CoJ) Metropolitan Municipality.

“The findings underscore the limitations of classical dichotomy theory, particularly in accounting for the intersectionality between coalition politics and the institutional architecture of local government. In contrast to the dichotomy discourse, which narrowly focuses on political principals and administrative office-bearers, this research situates the interface within a broader institutional and societal matrix that includes political parties, non-state actors, and citizen constituencies.”

Dr Du Plessis say although this study was confined to local government and the CoJ, he believes it makes a meaningful knowledge contribution with real-world impact, paving the way for continued exploration and innovation in both research and practice concerning the political-administrative interface in coalition-led metropolitan municipalities. “More importantly, I hope it sparks critical reflection on the central nervous system of government and governance in South Africa, highlighting the urgent need to reconfigure not only political and administrative arrangements, but also the broader governance frameworks required to manage coalition politics effectively.”

 

PhD journey 

Obtaining his PhD, Dr Du Plessis says, is extremely emotional as he hopes to have inspired the broader family and future generations of students. It is both a liberating and proud moment for him for which he is deeply grateful and extremely overjoyed. This is not only the achievement of a personal and academic goal, but also the fulfilment of a journey filled with perseverance, growth, and purpose.

Like most PhDs, his journey was characterised by challenges that not only tested his intellectual ability but also his drive to succeed. There were moments of “profound loneliness”, self-doubt and even an overwhelming sense of guilt and shame. He had to deal with mental health challenges and experienced the well-known imposter syndrome. However, the support from his wife, Natasha, and Prof Lues, as well as colleagues like Dr Marevé Biljohn, Head of the Department of Public Administration and Management, the Faculty of Economic and Management Sciences PhD support group under the leadership of Prof Tina Kotze and Mrs Igna du Plooy and the REAP programme under the leadership of Dr Henriette van der Berg and Dr Karen Booysen, were essential in completing his PhD. They guided him through the academic and emotional trials of this journey with unwavering compassion.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
