Opinion article by Prof Sethulego Matebesi, Associate Professor and Head of Department of Sociology, University of the Free State.
When a catastrophic accident cuts the first manned mission to Jupiter’s moons short in the Astronaut: The Last Push a 2012 American science fiction film – Michael Forrest, the sole remaining astronaut, must endure the three-year return trip to Earth alone. Similarly, how will the next five-year journey of local governance in South Africa manifest itself? Again, I reckon the responses from citizens will vary widely: from widespread cynicism to hope for a better future and from distrust of a dysfunctional system to the belief that service delivery will improve.

In an all-too-familiar scenario, political party campaigns have been littered with promises of how they best represent and advance voters’ interests. In doing so, two helpful facts about these campaigns emerge. The first is that the ANC, DA, EFF, and FF+ have realised that local contexts differ significantly and have framed their messages accordingly. A cursory glance at the broadcastings of these customised campaigns reveals that they aim to provide a safe psychological outlet for community-level concerns. The second is that, in general, the election messaging and adverts of the ANC ranged from apologies to bold statements about who wields power to change the face of local governance. Opposition parties focused on improving the local government system notoriously known for the disregard of citizens’ needs and providing an active voice for the voiceless.

And guess what?

Political parties and candidates may mobilise constituencies as much as they can. However, the next five years of local governance require a significant departure from its status of dysfunctionality to a competent, legitimate political institution that produces satisfactory political outcomes. This legislative and moral mandate depends entirely on local participation in elections.

The three dimensions of increasing voter participation

Better and more meaningful political participation in elections remains a concern in South Africa. In a report for the Ford Foundation, Hahrie Han, a political science professor at the University of California, proposes a framework that details increasing participation and making it more meaningful.

Firstly, people must be able to participate. Declaring election day as a public holiday, President Cyril Ramaphosa removed an important barrier to participation. While some may believe that election day will be just another public holiday, for others – particularly those who are working – there is no need to weigh up whether to take leave for a cause that will not significantly change their lives. Furthermore, the Independent Electoral Commission (IEC) has demonstrated a sense of moral urgency by drawing unprecedented public attention to their voting processes and procedures to protect voters and election officials from spreading the virus at the polling stations.

Secondly, people must want to participate. Here, political parties and election candidates should not take voting as a taken-for-granted part of the repertoire of residents’ political activities. Election campaigns – both online (internet) and offline (door-to-door engagements, posters, and billboards) remain a powerful medium to improve visibility and deliver messages to solicit interest from citizens. But once these campaigns conclude, still, it remains an individual’s choice to want to participate in the elections. While it is difficult to assess the level of voter engagement with the election campaigns under COVID-19 restrictions, the general political climate in South Africa seems to be conducive for free and fair elections. Yet political assassinations continue to cast a dark shadow over the local government elections. This cruel feature of political life in the country serves as an ultimate intimidation tactic. It denies candidates the right to stand for election and citizens to choose their preferred public representatives.

Thirdly, Hahn argues that for people to want to participate in the political process, their participation must matter. Therefore, aside from building a sense of agency and encouraging greater participation in elections, people still need to be convinced that their vote counts and influences decisions at the local level, where voters have the chance to participate directly in the election of local councillors.

Disrupting the balance of power in local councils 

Regardless of the challenges it faces, the ANC remains in pole position to retain most of the local councils it leads. I believe there is much to be discontented about, but opposition parties – including civic forums – have yet to build the power to break the stranglehold the ANC has on elections – and that is no small task.

Interestingly, in contrast to the DA, the ANC has paradoxically avoided announcing their mayoral candidates in direct response to prevent the electoral backlash it received in the metros during the 2016 local government elections. Yet, except for a few local councils in several provinces, the metros are precisely where the most significant disruption to the balance of power will occur. 

Whether political parties will deal with the standoffs of coalition politics in hung councils, while broaching complex issues, remains a concern for South Africans. But elections remain an excellent opportunity for citizens to participate and influence local political decision-making.

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.
