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.

Premiere of the documentary on King Moshoeshoe - Address by the Rector
2004-10-14

Address by the rector and vice-chancellor of the University of the Free State, prof Frederick Fourie, at the premiere of the documentary on King Moshoeshoe, Wednesday 13 October 2004

It is indeed a privilege to welcome you at this key event in the Centenary celebrations of the University of the Free State.

We are simultaneously celebrating 100 years of scholarship with 10 years of democracy

Today is a very important day with great significance for the University. This Centenary is not merely a celebration of an institution of a certain age. It is a key event in this particular phase of our history, in our transformation as an institution of higher learning, in taking the creation of a high-quality, equitable, non-racial, non-sexist, multicultural and multilingual university seriously.

This is about building something new out of the old, of creating new institutional cultures and values from diverse traditions.

It is about learning together - as an higher education institution - about who we are where we come from – to decide where we are going.

It is about merging the age-old tradition of the university, of the academic gown, with the Basotho blanket, the symbol of community engagement.

Then why is it important that we remember Moshoeshoe, where does he fit into our history?

In the Free State province, where large numbers of Basotho and Afrikaners (and others) now live together, a new post-apartheid society is being built in the 21st century.

The challenge is similar to that faced by Moshoeshoe 150 years ago. As you will see tonight, he did a remarkable thing in forging a new nation out of a fragmented society. He also created a remarkable spirit of reconciliation and a remarkable style of leadership.

Not all people in South Africa know the history of Moshoeshoe. Many Basotho – but not all – are well versed in the history of Moshoeshoe, and his name is honoured in many a street, town and township. Many white people know very little of him, or have a very constrained or even biased view of his role and legacy. In Africa and the world, he his much less known than, for instance, Shaka. (In Lesotho, obviously, he is widely recognised and praised.)

We already benefit from his legacy: the people of the Free State share a tradition of moderation and reconciliation rather than one of aggression and domination.

With Moshoeshoe, together with Afrikaner leaders and reconciliators such as President MT Steyn and Christiaan de Wet, we have much to be thankful for.

Our challenge is take this legacy further: to forge a new society in which different cultural, language and racial groups – Basotho, Afrikaners and others – will all feel truly at home.

Bit by bit, on school grounds, on university campuses, in each town and city, people must shape the values and principles that will mould this new non-racial, multicultural and multilingual society.

A shared sense of history, shared stories and shared heroes are important elements in such a process.

Through this documentary film about King Moshoeshoe, the UFS commits itself to developing a shared appreciation of the history of this country and to the establishment of the Free State Province as a model of reconciliation and nation-building.

Moshoeshoe is also a strong common element, and binding factor, in the relationship between South Africa / the Free State, and its neighbour, Lesotho.

For the University of the Free State this also is an integral part of real transformation – of creating a new unity amidst our diversity.

Transformation has so many aspects: whilst the composition of our student and staff populations have been changing, many other things change at the same time: new curricula, new research, new community service learning projects.

In also includes creation of new values, new (shared) histories, new (shared) heroes.

It includes the incorporation of the Qwaqwa campus, which serves a region where so many of the children of Moshoeshoe live, including her majesty Queen Mopeli.

We see in Moshoeshoe a model of African leadership – of reconciliation and nation-building – that can have a significant impact in South Africa and Africa as a whole.

We also find in the legacy of King Moshoeshoe the possibility of an “founding philosophy”, or “defining philosophy”, for the African renaissance.

To develop this philosophy, we must gain a deeper understanding of what really happened there, of his role, of his leadership.

Therefore the University of the Free State will encourage and support further research into the history, politics and sociology of the Moshoeshoe period, including his leadership style.

We hope to do this in partnership with National University of Lesotho.

The Moshoeshoe documentary is one element of a long-term project of the UFS. The other elements of the project that we are investigating are possible PhD-level research; a possible annual Moshoeshoe memorial lecture on African leadership; and then possible schools projects and other ways and symbols of honouring him.

It is my sincere wish that all communities of the Free State and of South Africa will be able to identify with the central themes of this documentary, and develop a shared appreciation for leaders such as King Moshoeshoe and the legacy of peace, reconciliation and nation-building that they have left us.
