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.”

“A graduation ceremony epitomises every student’s academic dream and pursuit, and allows you to look back as you enter the professional career of your choice.”

These were the words of guest speaker Dr Mafu Rakometsi, Chief Executive Officer of Umalusi, that resonated through the Callie Human Centre at this year’s Summer Graduation on the Bloemfontein Campus. He mentioned that today graduates would look back at a journey that started with hesitant steps, and despite all their ups and downs, they had managed to make it this far.

During the afternoon session, Prof Lis Lange, Vice-Rector: Academic, at the University of the Free State (UFS), said that graduations were always an occasion for celebration and this year, there were two reasons for these celebrations.

 “The first is simply that we made it through a difficult 2016 and the secondly because we are celebrating two crucial professions that will attribute to the well-being of this country, namely teachers and health practitioners.”

Meaningful graduation ceremony for Ferial Haffajee

This year, the UFS had the privilege and honour to confer editor-at-large at The Huffington Post SA, Ferial Haffajee, with an honorary doctorate in the Faculty of the Humanities.

Speaking after the graduation ceremony, Dr Haffajee said, “It was really, really meaningful for me, because I’ve never been able to graduate. When I finished university, it was during the struggle against apartheid, so we didn’t graduate. It was a wonderful day and wonderful to see the role that young people are playing on this campus.”

“Dr Ferial Haffajee has made a significant contribution to press freedom in South Africa. She is known both nationally and internationally for the work she has done and therefore it is an honour to welcome her as a Kovsie. She is one of the people who represent the values of the UFS. We are proud of her and we wish her great success,” said Prof Milagros Rivera, Head: Department of Communication Science and acting Dean of the Faculty of the Humanities at the UFS.

Inspiration drawn from graduation ceremonies

During his address, Dr Khotso Mokhele, the Chancellor of the UFS, made special mention of many that inspired him at the graduation ceremonies.

His inspirations included Dr Ambrotius Swartbooi, who suffered a spinal injury from a near-fatal car accident which left him paralysed and a quadriplegic, yet who still managed to receive his doctorate; Setsoane Ntseki, a matriculant with poise and an incredible voice, who delivered the song item; Judge Ian van der Merwe, Chairperson of the Council at the UFS and a close friend of Dr Mokhele, with whom he worked for many years; as well Dr Haffajee, a trail-blazer that many look up to.

Damian Viviers was recognised as one of the youngest PhD graduates in the Faculty of Law, where he received a PhD in Mercantile Law. He is a research fellow in the Department of Mercantile Law, and was recently appointed as candidate attorney in the commercial department at Phatshoane Henney Attorneys.

In closing, his message to the class of 2016 was simple, that even though the world and our country may find itself in an odd space now, the graduates needed to remember that even though they would become leaders, there was always something bigger than themselves.
