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.”

True leadership may mean admitting disunity
 

In this edited extract from the inaugural King Moshoeshoe Memorial Lecture at the University of the Free State, Professor Njabulo S Ndebele explores the leadership challenges facing South Africa

RECENT events have created a sense that we are undergoing a serious crisis of leadership in our new democracy. An increasing number of highly intelligent, sensitive and committed South Africans, across class, racial and cultural spectrums, confess to feeling uncertain and vulnerable as never before since 1994.

When indomitable optimists confess to having a sense of things unhinging, the misery of anxiety spreads. We have the sense that events are spiralling out of control and that no one among the leadership of the country seems to have a definitive handle on things.

There can be nothing more debilitating than a generalised and undefined sense of anxiety in the body politic. It breeds conspiracies and fear.

There is an impression that a very complex society has developed, in the last few years, a rather simple, centralised governance mechanism in the hope that delivery can be better and more quickly driven. The complexity of governance then gets located within a single structure of authority rather than in the devolved structures envisaged in the Constitution, which should interact with one another continuously, and in response to their specific settings, to achieve defined goals. Collapse in a single structure of authority, because there is no robust backup, can be catastrophic.

The autonomy of devolved structures presents itself as an impediment only when visionary cohesion collapses. Where such cohesion is strong, the impediment is only illusory, particularly when it encourages healthy competition, for example, among the provinces, or where a province develops a character that is not necessarily autonomous politically but rather distinctive and a special source of regional pride. Such competition brings vibrancy to the country. It does not necessarily challenge the centre.

Devolved autonomy is vital in the interests of sustainable governance. The failure of various structures to actualise their constitutionally defined roles should not be attributed to the failure of the prescribed governance mechanism. It is too early to say that what we have has not worked. The only viable corrective will be in our ability to be robust in identifying the problems and dealing with them concertedly.

We have never had social cohesion in South Africa — certainly not since the Natives’ Land Act of 1913. What we definitely have had over the decades is a mobilising vision. Could it be that the mobilising vision, mistaken for social cohesion, is cracking under the weight of the reality and extent of social reconstruction, and that the legitimate framework for debating these problems is collapsing? If that is so, are we witnessing a cumulative failure of leadership?

I am making a descriptive rather than an evaluative inquiry. I do not believe that there is any single entity to be blamed. It is simply that we may be a country in search of another line of approach. What will it be?

I would like to suggest two avenues of approach — an inclusive model and a counter-intuitive model of leadership.

In an inclusive approach, leadership is exercised not only by those who have been put in some position of power to steer an organisation or institution. Leadership is what all of us do when we express, sincerely, our deepest feelings and thoughts; when we do our work, whatever it is, with passion and integrity.

Counter-intuitive leadership lies in the ability of leaders to read a problematic situation, assess probable outcomes and then recognise that those outcomes will only compound the problem. Genuine leadership, in this sense, requires going against probability in seeking unexpected outcomes. That’s what happened when we avoided a civil war and ended up with an “unexpected” democracy.

Right now, we may very well hear desperate calls for unity, when the counter-intuitive imperative would be to acknowledge disunity. A declaration of unity where it manifestly does not appear to exist will fail to reassure.

Many within the “broad alliance” might have the view that the mobilising vision of old may have transformed into a strategy of executive steering with a disposition towards an expectation of compliance. No matter how compelling the reasons for that tendency, it may be seen as part of a cumulative process in which popular notions of democratic governance are apparently undermined and devalued; and where public uncertainty in the midst of seeming crisis induces fear which could freeze public thinking at a time when more voices ought to be heard.

Could it be that part of the problem is that we are unable to deal with the notion of opposition? We are horrified that any of us could be seen to have become “the opposition”. The word has been demonised. In reality, it is time we began to anticipate the arrival of a moment when there is no longer a single, overwhelmingly dominant political force as is currently the case. Such is the course of history. The measure of the maturity of the current political environment will be in how it can create conditions that anticipate that moment rather than seek to prevent it. We see here once more the essential creativity of the counter-intuitive imperative.

This is the formidable challenge of a popular post-apartheid political movement. Can it conceptually anticipate a future when it is no longer overwhelmingly in control, in the form in which it is currently, and resist, counter-intuitively, the temptation to prevent such an eventuality? Successfully resisting such an option would enable its current vision and its ultimate legacy to our country to manifest in different articulations, which then contend for social influence. In this way, the vision never really dies; it simply evolves into higher, more complex forms of itself. Consider the metaphor of flying ants replicating the ant community by establishing new ones.

We may certainly experience the meaning of comradeship differently, where we will now have “comrades on the other side”.

Any political movement that imagines itself as a perpetual entity should look at the compelling evidence of history. Few movements have survived those defining moments when they should have been more elastic, and that because they were not, did not live to see the next day.

I believe we may have reached a moment not fundamentally different from the sobering, yet uplifting and vision-making, nation-building realities that led to Kempton Park in the early ’90s. The difference between then and now is that the black majority is not facing white compatriots across the negotiating table. Rather, it is facing itself: perhaps really for the first time since 1994. Could we apply to ourselves the same degree of inventiveness and rigorous negotiation we displayed leading up to the adoption or our Constitution?

This is not a time for repeating old platitudes. It is the time, once more, for vision.

In the total scheme of things, the outcome could be as disastrous as it could be formative and uplifting, setting in place the conditions for a true renaissance that could be sustained for generations to come.
