The Scuppered Africa Dream

The year 2023 marks the diamond jubilee of the establishment of the Organisation of African Unity (OAU), currently known as the African Union (AU), which was founded in Addis Ababa. The visionary founders, including President Kwame Nkrumah and Emperor Haile Selassie, aimed to bring about political change in African states and restore the dignity of African people, who had long suffered under colonial subjugation and disenfranchisement. Their vision encompassed a united Africa, free from oppression, governed by self-determination, and destined for prosperity.

Over time, the OAU transformed into the AU, with the intention of accelerating the dream of African unity and eradicating the social, political, and economic challenges that had begun to define African states. Pan-Africanism emerged as a beacon of hope, inspiring many who understood its significance at the organisation's inception. As we reflect on the ideals cherished by the founding fathers and reaffirmed by their successors in 2002, it is crucial to contemplate four of the seventeen aims articulated during the launch of the African Union in Durban.

Unity and solidarity between African countries and their people

Firstly, the AU aims to achieve greater unity and solidarity between African countries and their people. In pursuit of this goal, notable actions have been taken, such as the establishment of the Peace and Security Council (PSC) to maintain peace in conflict zones such as Mali, Sudan, Somalia, and the Central African Republic. Moreover, in response to the COVID-19 pandemic, the AU set up the Africa Medical Supplies Platform (AMSP) to facilitate the procurement and distribution of medical equipment and supplies throughout the continent. While these achievements are commendable, the majority of the other intentions under this aim lack a concrete plan of action, and the lack of sufficient funding is hampering progress. This presents a cause for concern.

Secondly, the AU pledged to defend the sovereignty, territorial integrity, and independence of its member states. Despite the development of intervention instruments to support this aim, the organisation has been found wanting at critical junctures. One cannot forget the adoption of Resolution 1973 by the United Nations Security Council, which authorised national governments or regional organisations to impose a no-fly zone in Libya, ultimately leading to the assassination of Colonel Muammar Gaddafi. Colonel Gadhafi played a pivotal role in the formation of the African Union and declared his vision for the United States of Africa with a single government and one currency. Surprisingly, three AU member states – South Africa, Nigeria, and Gabon – voted in favour of this resolution. Their actions raised doubts about their commitment to defending the sovereignty, territorial integrity, and independence of the AU.

Africa faces a harsh reality

Africa, a continent with immense potential for growth and development, faces a harsh reality that cannot be ignored. Its burgeoning population holds great promise for contributing significantly to its advancement. Additionally, Africa is blessed with abundant mineral resources, the prudent management of which could sustain the developmental aspirations of its people. Furthermore, Africa's expansive land mass and diverse climate present valuable opportunities to address crucial concerns such as food and energy security. It is perplexing that Africa, a continent three times the size of the United States of America, continues to lag behind in all aspects of development. The continent has enormous potential to foster growth and development and to compete on a global scale. Regrettably, it has thus far failed to harness this potential, leaving the dream of African prosperity, initially envisioned by the founders of the OAU (AU) and their successors, frustratingly out of reach.

As we commemorate the diamond jubilee of the OAU's establishment, let it serve as a reminder of the vision and determination of its founders. Their dreams for an Africa united, free from oppression, and governed by self-determination still resonate today. It is our collective responsibility to ensure that these dreams are no longer scuppered, but rather transformed into a vibrant reality of African prosperity.

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.
