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.

Publication on indigenous knowledge systems
2005-10-21

UFS launches most comprehensive publication on indigenous knowledge systems
A unique collection of essays on Indigenous Knowledge Systems (IKS) was launched yesterday (20 October 2005) by the University of the Free State’s (UFS) Programme of Africa Studies.

The essays are published as a special edition of INDILINGA, the African Journal for Indigenous Knowledge Systems and is an outcome of the colloquium on Indigenous Knowledge Systems that was presented last year by the UFS Director of Africa Studies in cooperation with the National Research Council.

“The amount and diversity of materials on IKS brought together under one cover is unique as there are no other South African publications of this magnitude on this issue.  It contains papers of international experts on IKS such as Prof Fritz Wallner from Austria and Prof Gayatri Spivak, foremost postcolonial theorist from India,” said Prof Philip Nel, Director of Africa Studies and guest editor of the publication.

“The publication is a rich source field for students and scholars to exploit because most of the sources quoted in the articles are recent, fresh and relevant.  The contributors are largely people responsible for managing, fostering and studying IKS in a responsible manner,” said Prof Nel.

“An added value of the publication is the inclusion of the policy document on IKS that was adopted by Cabinet in November 2004,” said Prof Nel.


“Millions of people in South Africa are faced with the painful choice of abandoning their heritage.  In this choice, the study and management of IKS has a major role to play; on the one hand, to encourage as much assimilation of traditional knowledge as possible into the modern systems, and on the other hand to provide a “language” and a “grammar” for indigenous people through which they can access modernity,” said Prof Nel.

The IKS debate involves questions of African identity, protection of indigenous communities and practices, political aspects as well as the scientific integrity of the enterprise. 

The publication displays the range of burning questions that have to be resolved in this field such as mainstreaming IKS in academic debate and practice, recognition and protection of the knowledge holders, bio-prospecting and bio-piracy, bio and ethnic healing, lack of textbooks and field manuals, etc and will prove worthwhile for future researchers.

 “One of the main reasons for publishing this volume is the fact that IKS should be studied not only to provide a sense of pride in the past, or  to engender respect for indigenous peoples, but also to enable people in indigenous mind sets to make a better transition into the world of science and technology,” said Prof Nel.

The guest speaker at the launch was Dr Otsile Ntsoane, acting Director of IKS at the Department of Science and Technology.  In his speech Dr Ntsoane stressed the symbolic and concrete value of the publication.  “The publication can have a great social impact and the research results can contribute to chancing the economic landscape of South Africa,” he said.

The publication can be purchased at R150 per copy.  For more information, Ms Steffi Cawood, Programme Coordinator for Africa Studies at the UFS can be contacted at (051) 401-2614.
