It has been a year since the president signed off on the amendment bill to include South African Sign Language (SASL) as one of the country’s official languages. And one may wonder, what has changed since then? After all, many individuals and organisations, including the Deaf Federation of South Africa (DeafSA), the National Institute for the Deaf (NID), and Deaf rights activists from the Deaf community, believed that official recognition of sign language would lead to significant developments for SASL and the Deaf community.

Since then, SASL has mostly benefited from exposure from the SASL Indabas that PanSALB held on 9-10 March 2023 and another one on the 1-2 February this year. These Indabas were aimed at “discussing the standardisation of SASL and mapping a way forward”. They included several stakeholders, including our very own institution. They also had an impact on the development of SASL in various institutions, including UNISA and University of Cape Town (UCT), and it is hoped that this influence will extend to other institutions.

However, one must not overlook the fact that despite being a minority language, SASL already enjoyed significant language rights. For example, the South African Schools Act recognised it as an official language in 1996. The Use of Official Languages Act of 2012 provided another benefit that was not even enjoyed by the other 11 official languages; with this act, state entities had to establish a language policy outlining the use of official languages for public communication, specifically if a member of the public chose SASL as their preferred language. It also benefited from protection under the South African Sign Language Charter, launched by the SASL NLB (National Language Board) in 2020, roughly three years before it became official. Even Prof Theodorus du Plessis, Professor Emeritus in the Department of South African Sign Language and Deaf Studies, University of the Free State (UFS), in a previous opinion article, mentioned that there would be little to gain from officially recognising SASL, aside from the added symbolism associated with such a move. As a matter of fact, SASL had more to lose than gain due to its official recognition, as you will learn later in the article.

A human rights level

On a human rights level, which is more relevant to those living with hearing impairments in the country, the officialisation of SASL still had no significant effect on any of their human rights. This is simply because these persons already enjoyed their rights. However, what the officialisation cost the Deaf community* is the privilege as mentioned earlier that the Use of Official Languages Act of 2012 provided – users of SASL having the right to choose SASL as their language of interaction with the state – the very one that official languages do not enjoy. This is thus a disadvantage to the Deaf community, considering that they already suffer from a lack of interpreters in the county. An article by Nicky Bezuidenhout early this year highlighted that there is a “lack of access to crucial services like healthcare and justice due to a shortage of qualified South African Sign Language (SASL) interpreters”. Therefore, many Deaf people rely on untrained or unqualified individuals and mostly even family members to act as interpreters. This was mostly the case in my life, being a CODA (Child of a Deaf Adult) and having to interpret for my parents. And besides my proficiency in SASL, there was still the matter of a breach of confidentiality. This is a common problem for many people. Therefore, more SASL interpreters (SASLi) are needed. Additionally, it is up to everyone to take it upon themselves to learn SASL through the various provisions that are available today.

More development for SASL as a language

Thankfully, the UFS, among a few other institutions such as the Wits University, North-West University as well as the Durban University of Technology, makes such a provision through its SASL short course. Another way to learn is through mobile applications such as DEAFinition and the NID SASL Dictionary. The previous platforms also offer inexpensive online courses. This way, one can be equipped with SASL fundamentals to at least be able to hold a conversation without the need for an interpreter. Furthermore, we can only anticipate that since SASL is officially recognised, it will become more accessible in higher education institutions, as mentioned earlier, and will be included in the South African school curriculum, particularly for mainstream schools. As a result, more people will have the opportunity to learn SASL. Moreover, we can expect to see an increase in the number of qualified teachers with not only teaching skills but also proficiency in SASL.

Nonetheless, it has only been a year and matters regarding language plans and policies often require a great amount of resources, with time being the greatest of all. We can only hope that its officialisation has indeed led to the cultural acceptance of SASL and the relevant community, promoting substantive equality, and preventing unfair discrimination based on disability. But more importantly, we hope that this is not the end of the road for SASL in terms of its development as a language.

*Footnote: It is important to make a distinction between deaf people who are deaf but do not identify as part of the Deaf community and do not use SASL (who are referred to with a lowercase “d’’), and those who are deaf and are part of the Deaf community, making use of SASL as their first language (who are referred to using a capitalised ‘D’).

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.
