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.

Conference on religion and reconciliation
2011-07-25

 

At the conference were, from the left, front: Dr Frank Chikane, President of AFM International; Dr Mathole Motshekga, Chief Whip of the ANC; at the back: Rev. Maniraj Sukdaven, Head of our Department of Religion Studies; and Dr Alan Boesak, connected to our International Institute for Studies in Race, Reconciliation and Social Justice, as well as a minister in the United Reformed Church.

In recent times, reconciliation has mainly been politically driven, Dr Alan Boesak stated during a conference on religion and reconciliation. He was one of a number of prominent academic leaders from various religions who participated in the conference: Exploring religious understanding for reconciliation.The conference was presented by our Faculty of Theology and the International Institute for Studies in Race, Reconciliation and Social Justice at our university this week.

According to Dr Boesak, a theologian connected to our International Institute for Studies in Race, Reconciliation and Social Justice, reconciliation means much more than simply former enemies no longer attacking or killing one another; they also have co-exist with a positive attitude towards one another.
 
Speakers from, amongst others, the Christian, Jewish, Baha’i, Rastafarian, Islam and Buddhist religious communities shared their views on reconciliation with one another.Most of these speakers referred to the special value of humankind in each religion. A person’s life has a supernatural dimension, which ought to play a major role in the way in which people treat one another.
 
Dr Frank Chikane, President of AFM International, as well as a speaker at the event, stated that the religious community should and had to be more active in discussions about reconciliation.“If religious leaders do not talk about current issues, all kinds of voices with distorted perspectives will be heard instead,” Dr Chikane added.
 
Reconciliation can only truly take place if the contribution of each group in society is taken seriously. Apart from the high premium placed on rights in society, duties that have to be fulfilled should also be emphasised. Bishop Malusi Mpumlwana from the Ethiopian Episcopal Church is of the opinion that this sense of duty should be established in people’s frame of mind. Adv. Antony Osler pointed out from a Buddhist perspective how important it was to deal with reconciliation by living up to its principles.
 
Rev. Maniraj Sukdaven, Head of our Department of Religion Studies, is very satisfied with the high quality of the contributions during the conference.
