The UFS Centre for Gender and Africa Studies, in conjunction with the South African Institute of Race Relations (IRR), recently hosted the fifth instalment of the Africa Dialogue Series. The webinar series – established by Prof Hussein Solomon – has rapidly grown in stature. The latest discussion on the SA Election Aftermath: Economic, Security and Political Considerations drew high-profile international attendance that included several ambassadors, military attachés, and representatives of security communities.

“Part of the success of the Africa Dialogue Series,” Prof Solomon says, “is that we include a variety of speakers in each discussion. This ensures that the conversation remains relevant.” 

Economic challenges amid coalition governments

Prof Philippe Burger, Dean of the UFS Faculty of Economic and Management Sciences, opened the discussion by highlighting the complexities of coalition governments in South Africa – especially given the country’s lack of experience with such political arrangements. Prof Burger further pointed out the difficulty of managing coalitions amid economic stagnation, high unemployment, poverty, and mounting debt. At the time, Prof Burger forecast that a coalition with the Democratic Alliance (DA) might push for pro-market reforms, but that such an agreement could still suffer from instability due to ideological differences. Prof Burger predicted a ‘rocky five years’ ahead for any coalition government.

A shift in security strategy

Transitioning to security matters, Eeben Barlow, Chairman and CEO of Executive Outcomes, stressed the paramount importance of a robust national security strategy for the new government's stability and South Africa's interests. He advocated for a comprehensive reassessment of the current strategy, urging a shift from reactive policies to a proactive, pre-emptive approach. Barlow underscored the need to align intelligence, law enforcement, and military efforts within this revamped strategy through proper structuring, training, and resourcing. He warned that without comprehensive security planning and decisive implementation, South Africa risks further instability, economic decline, and international reputational damage.

Political fragmentation

Next, Terence Corrigan, Project and Publication Manager at the IRR, offered a sobering analysis of the election results. He noted the severe weakening of the previously dominant ANC, which no longer serves as the nation's ‘moral voice’. Despite this, the opposition failed to capitalise decisively, with the DA potentially reaching its voter ceiling. Corrigan expressed concern over the rise of anti-constitutional parties such as the EFF and MK, which exploit public grievances and pose a ‘populist challenge’ to democratic institutions. He predicted increased political fragmentation and ‘fractious politics’ as South Africa navigates this political landscape.

Legislative gridlock and electoral reform

Adding to the discussion of political challenges, Marius Roodt, Deputy Editor of Daily Friend, noted the worrying decline in voter turnout, and reiterated the concerns regarding South Africa’s fragmented politics. Roodt warned that this fragmentation could lead to legislative gridlocks from minority governments or unstable coalitions unable to pass laws. To address these issues, he proposed electoral reforms, including minimum vote share thresholds, extended time frames for forming governments, binding coalition agreements, and restrictions on motions of no confidence. While some view gridlock as a check against radical policies, Roodt acknowledged that an inability to pass the necessary laws could hamper investment.

Broader political implications

Concluding the presentations, Sanet Solomon, a political analyst and lecturer at UNISA, provided an overarching analysis of South Africa's political landscape post-elections. She called attention to the historic significance of three decades of democracy and fluctuating voter turnout influenced by various challenges and achievements. Solomon emphasised the critical nature of policy alignment in coalitions, particularly the ANC's collaboration with the DA. She also discussed the complexities of maintaining macroeconomic stability, the urgent need for rule of law and anti-corruption measures, and the importance of strategic, cohesive policy making in the nation's future.

The webinar underscored the multifaceted challenges facing South Africa's new coalition government, highlighting the need for strategic economic, security, and political planning to navigate the uncertain road ahead.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
