The inaugural Faculty of Natural and Agricultural Sciences (NAS) Research Conference at the University of the Free State (UFS) signalled a decisive shift in how science is being imagined and practised at the institution. The two-day gathering, which took place on 1 and 2 July 2025, not only showcased research excellence, but also marked the official launch of two flagship initiatives: the Green Futures Hub and the Complex Systems Hub. Both are designed to enable transdisciplinary research that connects across fields, responds to global and local challenges, and contributes to the university’s Vision 130 strategy.

The conference theme, Integrating science for societal impact and a sustainable future, framed the programme, which featured presentations by researchers, postgraduate students, and postdoctoral fellows across all NAS disciplines. Opening the event, Prof Paul Oberholster, Dean of the Faculty of Natural and Agricultural Sciences, said: “This is more than a research gathering. It’s a signal – a step forward in our faculty’s approach to science, innovation, and impact.”

He emphasised that in a world marked by climate instability, digital disruption, and growing inequality, science must step forward not only to understand the world, but also to help shape it. “Our goal is to create research pathways that are sustainable, collaborative, and responsive to both local and global needs,” he said. The Green Futures Hub and the Complex Systems Hub are practical, future-facing platforms that make that vision real – connecting researchers, government, industry, and communities, he explained.

 

A catalyst for agricultural and environmental transformation

Prof Wayne Truter, Executive Manager of the Green Futures Hub, introduced the initiative as a catalyst for bringing applied science and sustainability together. He asked how innovation can translate into practical solutions that serve society and the environment. “We often focus so deeply on our disciplines that we forget to ask how our work creates social and economic impact,” he said.

The Green Futures Hub is a virtual platform and flagship of agricultural and environmental stewardship and sustainable development. It fosters partnerships that unleash value through nature-based solutions, land rehabilitation, climate risk finance, water resource management, bio-energy innovations, and more – by connecting researchers with industry, government, and international stakeholders. It also supports initiatives that enhance food and water security, investigate the coexistence of mining and agriculture, and address the carbon and nitrogen economy. The hub serves as a space for funding, knowledge transfer, and community transformation.

Prof Truter noted that complex societal challenges – from sustainable agriculture to the energy transition – cannot be solved by isolated disciplines. “Research must be applied in ways that industry and communities can understand and value,” he said. “If we want businesses to believe in science, we must speak their language and show relevance. The Green Futures Hub exists to bridge that gap.”

 

Science that responds to complexity

Prof Oberholster explained that the faculty’s second major initiative – the Complex Systems Hub – is designed to equip researchers to solve pressing problems in a digitally interconnected age. By bringing together data science, AI, advanced modelling, and interdisciplinary design, the hub strengthens the university’s ability to respond to global challenges.

“These are not abstract concepts,” he said. “They are practical responses to the question: how can we do science that matters?”

Dr Jacques Maritz, Head of the Unit for Engineering Sciences, who presented the launch, emphasised that complexity is not a threat to science – it is a source of innovation. “Scalability, unpredictability, nonlinearity, and emergence – these aren’t just buzzwords. They define the future of research.”

The Complex Systems Hub is a digital platform that enables agile, multidisciplinary teams to develop integrated responses to major issues such as climate change, pandemics, and space science. It connects NAS entities such as the Green Futures Hub, the One Health Centre of Excellence, and Advanced Materials Research to foster collaboration and innovation.

Dr Maritz explained that the hub bridges academic research and real-world application by creating spaces where diverse fields intersect. “If we want research to move from lab scale to real-world solutions, we need diverse teams working together – no single field can do this alone.”

Current projects include eco-friendly materials for sustainable construction, scientific water management using algae, and genomic surveillance for public health – all united by one goal: to turn complexity into opportunity and data into direction.

 

Bringing research closer to impact

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation, officially opened the conference and praised the faculty for its foresight and leadership. “This conference is not only about exchanging ideas,” he said, “but about igniting conversations that matter.” Science, he noted, is not a luxury of the privileged, but “the lifeblood of progress,” and its success must be measured not only in citations but in consequences.

He reminded delegates that global challenges such as climate change, food insecurity, and biodiversity loss are no longer distant threats, but urgent realities. “Science must respond – not with silence, but with solutions and deeper questions.”

Referencing the university’s Vision 130 strategy, Prof Reddy said the goal is not just to be research-intensive, but to reimagine the role of science in society. “The world doesn’t necessarily need more data,” he said. “It needs more direction. If our research does not touch lives, it is not reaching far enough.”

He described the conference as a space to “plant ideas, cross-pollinate disciplines, and harvest innovation,” and applauded the launch of the two new research hubs as engines of hope and practical impact. Addressing postgraduate students and early-career researchers directly, he encouraged them to be curious, collaborative, and courageous: “You are not simply here to follow footsteps. You are here to forge new paths.”

 

Building a future grounded in our own narratives

Prof Bonang Mohale, the Chancellor, reminded delegates that science cannot be separated from history, context, or social justice. Quoting Emeritus Professor J Edward Chamberlin, he asked: “If this is your land, where are your stories?” He challenged researchers to ensure that science is not only excellent but also rooted in African realities and driven by the desire to transform society.

“Those nations that make English compulsory but agriculture optional are destined to produce a citizenry that speaks fluently – but on an empty stomach,” he said. “We must do science that describes, defines, and shapes this country in our own image.”

 

A faculty on the move

Over the two-day programme, students and researchers presented cutting-edge work aligned with the faculty’s wide range of disciplines and the university’s strategic research goals. The conference replaced the Flash Fact competition as NAS’s flagship research platform.

In closing, Prof Oberholster invited delegates to make the most of the opportunity to engage across disciplines. “Let’s ensure that the science we do here continues to transform lives – locally, nationally, and globally.”

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
