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.”

The Faculty of the Humanities and Centre for Africa Studies rewarded the contributions of Dr Lakhdar Brahimi, a prominent global peace leader, with an honorary doctorate on Thursday 2 July 2015.

The conferment formed one of the highlights of the 2015 Winter Graduations. Dr Brahimi’s work as a United Nations’ (UN) envoy, and African peace leader of note, was deeply respected by the university. Professor Heidi Hudson, Director of the Centre for Africa Studies at the UFS, accepted the PhD on his behalf.

In his acceptance speech, read by Prof Hudson at the Chancellor’s Dinner the same evening, Dr Brahimi expressed his gratitude to the university. “I deeply appreciate your generous recognition, and even now, in the twilight years of my life, I shall try to be worthy of your confidence in everything I say or do.”

“My generation did its share: its successes and its failures are things of the past. We must accept to be judged by you, the graduates. You, the young graduates here at the University of the Free State, and your fellow members of the African intellectual elite, have an exciting opportunity to take on the challenges and fulfil the dreams you have. We must accept to be judged by you.”

Algerian-born Dr Brahimi was first involved with the UN in 1992 as rapporteur to the Earth Summit. Distinctively, he is the most-frequently appointed special envoy of the UN. Amongst many other countries, he has worked as a mediator for South Africa, Haiti, Afghanistan, Iraq, Syria, Democratic Republic of Congo, Cameroon, Burundi, Angola, Liberia, Nigeria, Sudan, and Côte d’Ivoire on behalf of the UN.

Significant peacekeeping efforts in South Africa (1993- 1994)

The ambassador– in his capacity as special representative to South Africa from December 1993 to June 1994 –played a direct role in South Africa’s democratic transition.

Prof Hudson expressed appreciation for the ambassador’s role in facilitating a peaceful transition from South Africa’s Nationalist government into the current democratic dispensation.

“One of the reasons we selected him as recipient of the honorary doctorate, is because of what he did for the African continent,” she said.

In addition, she commented Dr Brahimi for being a living testament of Ubuntu. “He has displayed an ethic of humanism in everything that he has done, in the way that he has mediated in certain conflicts - his main contribution is as a mediator.

According to Hudson, his humility, modesty, and generosity are the epitome of Ubuntu which states that “I am because we are.”

Dr Brahimi as a global peace practitioner

Dr Brahimi served as Undersecretary-General of the Arab League, Arab League Special Envoy for Lebanon, and Foreign Minister of Algeria.

The UN Peace-building Commission was established as a result of recommendations in his2000 Report of the Panel on United Nations Peace Operations (Brahimi Report).

Since 2007, Dr Brahimi has been a member in The Elders - an alliance chaired by Kofi Annan -of peace and human rights advocates including Desmond Tutu, Graça Machel, Mary Robinson, and Jimmy Carter. His passion for justice led to his membership in the Commission on Legal Empowerment of the Poor.

In 2010, he was Laureate of the Special Jury Prize for Conflict Prevention, awarded by the Chirac Foundation (France), which promotes international peace and security.

Dr Brahimi’s influence in Peace Education

The Brahimi Report has had an indelible impact on scholars specialising in the broad field of peace operations. Dr Brahimi’s writings have also contributed to knowledge on post-conflict reconstruction and development (PCRD), a signification part of the African Union’s narrative.

He is a distinguished senior fellow at the Centre for the Study of Global Governance at the London School of Economics. He has taught a postgraduate course on Conflict Resolution at Sciences Po, Paris (2011); is Andrew D. White Professor-at-Large at Cornell University; and is affiliated to the Institute for Advanced Studies at Princeton, where he was a visiting professor from 2006 to 2008.

In addition, Dr Brahimi is a founding member of the French-language Journal of Palestine Studies, and a board member of the Stockholm International Peace Research Institute.
