Nombulelo Shange says this year it is important to look inward, focus on individual healing, growth and reflect on the losses pre- and post-COVID-19.

With Human Rights Day nearing it is important to remember the sacrifice of those who lost their lives in the 1960 Sharpeville Massacre in the fight for our freedom. This year I think it is also important to look inward, focus on individual healing, growth and reflect on the losses pre- and post-COVID-19.

The strength and resilience of the Sharpeville community is an important reminder of the hardship we have to overcome; it is an important reminder that we can overcome even this challenge. But on this Human Rights Day our strength lies in our vulnerability and being strong enough to admit we are not okay and ask for help even when societal norms make it hard to do so. Do this without being embarrassed or carry resentment when those we lean on can’t be there because they are also not coping. And for those who give a lot of themselves, it is okay to admit that you have nothing left to give and that you need time to replenish yourself because you can’t bring light into other people’s lives while your own flame is dimming.

The collective cannot be strong when individuals are broken

Many of us were raised in families where communalism, ubuntu and caring for the collective are prioritised over the individual. And to put ourselves and our own wellbeing first feels like a betrayal of these virtues we were brought up with. But I would argue the opposite is true, the collective cannot be strong when it is made up of broken individuals.

Not putting ourselves first would be a betrayal to the same ideals of ubuntu many of us were brought up with. It sounds like a contradiction because we are taught to look at the world in polarised ways and ubuntu ends up being portrayed as a philosophy that puts the masses first and sometimes at the expense of the individual. We see this kind of thinking and application in our own lives where families and communities at times uncritically impose ideas and practices that seemingly benefit the community over individuals. We see it in African discourse that theorises ubuntu and its relevance to traditional and modern spaces, its relevance in human rights discourse, decolonial discourse that broadly calls for “African solutions for African problems”. All of these are important and provide useful analysis, but they sometimes erase the individual.

Individualism is associated with Western imperialism and is rejected and vilified

Individualism is often rejected and vilified because it is associated with Western imperialism that saw the introduction of a greedy capitalist system in Africa that goes against almost every core belief we have. The capitalist system broke our connection to the environment and turned it into a commodity to be exploited for economic gain. It pushed competition and individual wealth over social wellbeing and community. And most importantly it took everything from Africans, our land, language, culture and sense of self. So as we grow and rebuild, it is difficult for us to imagine that these two seemingly contradictory ideals can coexist, where individualism is celebrated and encouraged for the betterment of a collective that will be stronger because it is made up of strong individuals. Instead we polarise, we conclude that if Western imperialism is exploitive and individualism is closely associated with it, then individualism must be bad too. If ubuntu and the collectivist thought around it protected the environment and promoted social wellbeing, then collectivism is good and to question it is to put your own selfish individual needs over the needs of the community and collective human rights.

But if we step away and look at ubuntu beyond our polarised ways of thinking, we see that ubuntu does place a great deal of importance on the individual. The main theoretical tenet of ubuntu says, “Umuntu ngumuntu ngabantu”, which translates to “I am because we are”. This expression shows the mutually beneficial coexistence of the individual and the collective. The collective is nothing without the individuals, and if the individuals who make up the collective are weak, the collective will also be weak. Individuals also need the community for their own enrichment, sense of self and overall wellbeing. If individuals are not nurtured and supported by the collective, they will not be able to give back to the collective, and the cycle continues.

It is time for us to focus on healing and introspection

So, what do we do when our collectivism is threatened by a global pandemic that is threatening to topple even the world’s strongest nations? What do we do when we can no longer tap into the collective strength we have built everything on? So much of our way of life is built on this collective strength as Africans, from the monthly stokvel meetings that offer people solutions to the worst socioeconomic challenges, while offering support and strength. Even church spaces are more than just a place to worship. It is here where people discuss the challenges faced by the community and offer whatever they can to address them. Our funerals and weddings do not just bring families together they bring communities together in shared grief or celebration. You do not even have to invite neighbours to events. The moment they see the tents, chairs, animal sacrifice etc arrive, they come days prior to the event to help the family prepare, celebrate, or cry. Even our ritualistic healing practices are not an individual lonely process in the way that Western biomedical models offer healing. At some point or another, the involvement of family and even the community will become important in African healing practices.

COVID-19 has threatened all of this and future environmental and public health crises might test us even more than COVID-19 has. I think this is the time for us to focus on healing and introspection, many of us were broken long before the pandemic hit. We have carried past intergenerational traumas into our present, but we have an opportunity to ensure that we do not carry them into our futures. We have been depleted by systems that seek to erase our entire existence as people of colour, women, LGBT+ communities and people with disabilities. After a while we start to believe that we are not worthy of love, we believe our poverty is a result of our own laziness and discount the fact that we have been starved of opportunities and resources. We stop challenging the abuses of our individual and collective human rights. This forced isolation is an ideal time to reflect on these things, heal and build ourselves as individuals through talking and sharing deep intimate pain with loved ones, trying to be in nature, attempting to “phahla” or mediate. The process will be different for everyone. Our own mental health depends on it and so does part of our ability to access our human rights. The restoration of our strength as communities will also depend on it during COVID-19 and beyond.

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.
