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.

State of our campuses: Impact of non-completion of the 2016 academic year on UFS students
2016-10-08

Dear Parents/Guardians and Students,

Impact of non-completion of the 2016 academic year

The University of the Free State (UFS) reiterates its support and commitment to the cause of free higher education. We have stated our position in all the available spaces. We want to work with UFS students to put pressure on the government to commit itself to accept the many suggestions put forward to make free education possible within a negotiated timeframe.

We are also seriously committed to our responsibility of providing education to all students enrolled at the university. We are doing our outmost to ensure that we can resume academic activities next week.

Description: " Academic non-completion 2016 Tags: " Academic non-completion 2016

We want to bring to your attention what will happen to individual students if the UFS cannot resume classes fully on Monday 10 October 2016.

Currently we have extended the academic year by one week. Some faculties are working on Saturdays and Sundays, starting earlier and finishing later to complete the material that needs to be taught and the practical work that students need to do to be able to write exams.

In the three biggest faculties at the university: Education, the Humanities, and Natural Sciences, this is what will happen:

  • Education will fail to graduate 1 193 students
  • Humanities will fail to graduate 1 125 students
  • Natural and Agricultural Sciences will fail to graduate 1 390 students

In the professional faculties: Economic and Management Sciences, Health Sciences, and Law, this will happen:

  • Economic and Management Sciences will fail to graduate 997 students
  • Health Sciences will fail to graduate 633 students
  • Law will fail to graduate 619 students

In total, approximately 6 000 students will not receive complete transcripts of their degrees and the certificates for their qualifications.

The university currently has 3 238 students on NSFAS bursaries. None of these students will be able to apply for bursaries for the lost year. They will be regarded as having failed or not completed their courses. They will not only miss this year, but the opportunity of studying in the future.

These students come from families to which their success in higher education was supposed to mean a change in the future of the entire family. Some parents/guardians hold more than one job to be able to pay tuition fees.

In not allowing the year to continue and students to finish, we are throwing away the efforts that entire families of poor people have made for four or five years to put their children through university. The promise of free education for future generations means nothing to these families who are poor in the present.

In terms of the academic calendar, it is a false argument to say that universities will be able to enrol first-years, because what 2016 students will miss, is the second semester.

We do not have the capacity to teach double the number of students in the second semester. This also misses the point that those students who were completing modules in order to graduate, will waste an entire year (assuming they have funding) to complete their degrees. This argument does not see the knock-on effect that students, not promoting in modules from first to second and second to third year, etc., will have. Finally, this also misses the point of what will happen to students who have to repeat first-semester modules.

In terms of academic staff, students are discounting the willingness of academic staff to teach double or to have the academic year extended by approximately six weeks between teaching and examinations. The same can be said for all the administrative and support staff required for running the university.

In our case, all the students in the University Preparation Programme (UPP) on the South Campus in Bloemfontein will be stuck without being able to move into mainstream modules, preventing a new intake of UPP students for 2017. These are the poorest and most disadvantaged students at the UFS.

It is absolutely necessary to find a means of protest and political action that will not jeopardise the future of current students and the country’s desperate need for critical skills.  The interdict against violent protest secured by the UFS is still in force. The police will intervene if the interdict is not respected and the UFS will have no control over police actions.

We trust that parents/guardians and students understand the implications of the situation.

Kind regards,

Prof Nicky Morgan
Acting Rector
University of the Free State
