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.

Qwaqwa Campus’s Teaching and Learning Champs scoop up award

Action research to improve classroom practice and student success rates, recently received a boost when the Qwaqwa Campus’s Teaching and Learning (TL) Champions were honoured with the prestigious UFS Vice-Chancellor’s Team Award. The award was in recognition of the team’s efforts to enhance professional development and was accompanied by a R50 000 prize that will be utilised to further encourage and develop a scholarly culture on the Qwaqwa Campus.

“An active learning community has developed over the past four years, which led to the creation of a scholarly forum for sharing problems, experiences and new knowledge”, revealed Dr Elize Smuts, who has been the pillar of strength in the development of TL Champs.

“This”, Dr Smuts said, “has continuously motivated the group to persevere in challenging and often under-resourced circumstances.”

 “Over a four-year period, 44 projects were undertaken, many with great success. Thirteen scholars participated in a pilot of CLASSE (Classroom Assessment of Student Engagement) in 2013. This survey, contextualised by staff from the Centre for Teaching and Learning, was a first in South Africa,” said Dr Smuts.

“The team undertook extensive literature reviews and attended numerous workshops on principles and practices of good teaching, research and writing. The two summarising booklets they prepared from two publications (How Learning Works: 7 Research-based Principles for Smart Teaching and Student Engagement Techniques) in 2013, will serve as guides and inspiration for the larger academic community of the UFS for many years.”

Since the formation of this team, TL scholars have presented 25 papers at 12 national and two international conferences.

“Taking into consideration that it is not easy to get an abstract accepted for presentation, these are impressive achievements,” Dr Smuts said.

“Some of the immediate results of scholars engaged in this project, include improved student success rates averaging 20% compared to only 8% improvement by academics who are not part of the project.”
 
“In 2013, one TL scholar reported student success rates that increased by 29%; another reported 80% on average; and another reported an increase from 65% to 95% in a class bigger than previous years.”

In congratulating the team, Centre for Teaching and Learning’s (CTL) Prof Annette Wilkinson said that she was very proud of the team.
 
“The team’s dedication and growth in scholarly practice – amidst challenging circumstances – are in my mind, the outstanding features of the project. I am very proud of the entire team”, said Prof Wilkinson.

The two presentations at international conferences were delivered by Ms Lea Koenig at the 32nd Annual Conference on the First-Year-Experience in Orlando, Florida and by Dr Elize Smuts in North Carolina. Both of these were presented in 2013.
