Prof Maryna Boshoff from the Department of Sustainable Food Systems and Development, Lerato Mamabolo (UFS graduate, now employed at OPUS Cactus), and Sotirios Pilafidis, Head of Research and Development at OPUS Cactus, at the XI International Congress on Cacti as Food, Fodder and Other Uses, hosted by the FAO-ICARDA CactusNet in Tenerife, Canary Islands.

The University of the Free State (UFS) has formalised a collaboration with OPUS Cactus, a pioneering biotech company focused on sustainable cactus-based farming and biorefineries in semi-arid regions. This partnership builds on OPUS Cactus’ expansion at the historic Waterkloof Research Station near Bloemfontein and combines the UFS’ academic expertise with industry innovation to promote climate-smart agriculture and economic development.

OPUS Cactus, led by Joeri van den Bovenkamp-Hofman, CEO, and Sotirios Pilafidis, Head of Research and Development (R&D), specialises in transforming marginal, non-arable land into productive, resource-efficient ecosystems by cultivating the drought-tolerant Opuntia cactus. This versatile biomass supports renewable bioenergy, animal feed, food production, fermentation feedstock, and sustainable biomaterials, while contributing to carbon capture and climate mitigation efforts.

“Our mission is to unlock the full potential of Opuntia biomass for sustainable bioenergy, food, and biomaterials, advancing regenerative agriculture and climate action,” says Van den Bovenkamp-Hofman. OPUS Cactus operates dual hubs: its headquarters and R&D lab in Groningen, the Netherlands, and the flagship 1 000-hectare Waterkloof Research Centre in the Free State. The Waterkloof facility serves as a commercial farm, research platform, and demonstration site for regenerative farming techniques.

The UFS collaboration involves multiple departments, including Sustainable Food Systems and Development, Soil, Crop and Climate Sciences, and Microbiology and Biochemistry. Profs Maryna Boshoff and Carlien Pohl-Albertyn, alongside Dr Gesine Coetzer, provide academic leadership in the partnership.

Prof Boshoff explains, “This industry-academia collaboration aims to develop innovative projects utilising cactus-based products. It builds on decades of cactus research at the UFS, enabling the translation of scientific knowledge into real-world impact through scale-up and commercialisation.”

 

Bridging academic research and commercial innovation to promote climate-smart agriculture

At the core of the partnership is the Waterkloof Research Centre, home to 42 spineless Burbank cactus pear cultivars. The facility acts as a ‘living laboratory’, integrating empirical research with commercial-scale farming. “Waterkloof now offers students and researchers access to operational infrastructure that cannot be replicated in conventional academic settings,” says Prof Boshoff.

Continuing projects at Waterkloof include biogas production through an anaerobic digester, regenerative agriculture practices such as cover cropping and reduced tillage, advanced plant biotechnology to breed superior cultivars, fermentation research for alternative proteins, and the development of novel fermented foods and sustainable biomaterials.

The collaboration also plays a critical role in conserving Opuntia genetic diversity and evaluating cultivars across South Africa’s varied agro-ecological zones. “Research done by UFS and ARC scientists on cultivar selection and cultivation is applied and scaled up through OPUS Cactus’ commercial operations,” Prof Boshoff adds.

This partnership provides valuable hands-on experience and career pathways for postgraduate students and young researchers. “We offer internships and employment opportunities, with several recent UFS graduates already joining our R&D team,” says Pilafidis. “We actively seek motivated graduates passionate about sustainable agriculture and bioengineering.”

By converting semi-arid landscapes into productive, carbon-sequestering ecosystems, the UFS-OPUS Cactus collaboration exemplifies how scientific innovation, entrepreneurship, and environmental stewardship can drive climate resilience, food security, and sustainable economic growth.

“OPUS Cactus is a win for the environment, communities, and business alike,” concludes Van den Bovenkamp-Hofman.

The science of translation
2015-09-16

What is the relationship between a translator, information, and an audience? Professor Christiane Nord explored the connection in a series of lectures hosted by the Linguistics and Language Practice Department and the Department of Hebrew of the University of the Free State (UFS) Bloemfontein Campus.

Since 2007, the professor for Translation Studies has been a research associate and professor extraordinary in the department, assisting translation and interpreting students in gaining a global perspective on their disciplines.

The world-renowned German scholar and trained translator for Spanish and English is also an author, with over 200 published articles on the so-called Skopos Theory, which formed the basis of the lectures on 7 and 8 September 2015. The addresses were centered on the functionality and limitations of translations.

Translation as a purposeful activity

According to Prof Nord, all translations should be geared towards conveying messages which the audience understands. This communicative purpose involves taking into consideration the cultural background of the recipient.

As a seasoned practitioner, Prof Nord has been guided by Skopos Theory in her teaching endeavours. Hence her firm stance: “If you do not have a theory, you cannot justify your translational decisions.”

Within the context of the Skopos Theory, she explains that, in order to produce a functional translation, the translator must analyse the purpose of the translated text, which includes the questions for whom, when, where, and through which medium will it reach the intended audience.

How to deal with doubt in functional translation

“Doubt is something we are accompanied by when we’re translating.” Such doubt may be caused by “insufficient proficiency with regards to source and target languages and cultures, domain and terminological knowledge, and knowledge in translation theory and methodology,” said Prof Nord. However, the top-down approach offers a solution to overcome uncertainty, at least to some extent. This approach considers, first and foremost, the target audience for which the translation is tailored. Based on this consideration, the translator is able to determine the approach that is most suitable for the audience, hence eliminating doubt.

In sum, the extraordinary professor asserted that there are no rules for translation, contrary to popular belief. According to Prof Nord, the main focus of a translator or interpreter should be to produce texts in the target language and culture which meet the requirements of the translation brief set by the client or commissioner.
