Graduation was held on Tuesday, 25 March, marking a significant milestone in the academic journey of Dr Nkosinathi Nxumalo. Growing up in the rural area of Ematholeni Reserve in Empangeni kwesakwaMthethwa, the prospect of pursuing higher education once felt like a distant dream. Financial challenges at home made the idea of attending university—let alone earning a PhD—seem nearly impossible. However, through determination, resilience, and the support of funding bodies such as NSFAS and the NRF, this dream became a reality.

Dr Nxumalo completed high school at Welabasha High School in 2010 and took a gap year in 2011. In 2012, he enrolled in a BSc in Animal Science at the University of Zululand, successfully completing the degree in 2015. His journey into research began with an NRF internship in 2016, which laid the foundation for his postgraduate studies. In 2017, he registered for an MSc in Animal Science, which he completed in 2019.

The most significant challenge in his academic career came in 2020, when he took the bold step of registering for a PhD in Animal Science (Breeding and Genetics) at Stellenbosch University. Relocating to the Western Cape was a major adjustment, made even more difficult by the onset of the COVID-19 pandemic. The uncertainty, isolation, and research delays led to moments of doubt, and at one point, he even considered returning home. However, with the unwavering support of his supervisor, Dr Molotsi, and his parents, he persevered through this challenging period.

His PhD research proved to be groundbreaking, presenting the first genome assembly of a southern African indigenous sheep breed. The study identified genes and genomic mechanisms that contribute to the adaptation of Nguni sheep (Zulu ecotype) to local environments, particularly their resilience to high temperatures and endemic diseases. Additionally, the research uncovered genetic links between the Zulu ecotype and European sheep populations, providing valuable insights into their history and evolutionary development.

As Dr Nxumalo celebrates this achievement, he reflects on a journey that was far from easy but ultimately shaped him into the researcher he is today. His story stands as a testament to the power of passion, perseverance, and the right support, proving that even the most ambitious dreams can be realised.

With the passing of Professor Wilhelm Eckart Kassier, South African agricultural economics bids farewell to a transformative figure. A visionary leader, an academic powerhouse, and a champion of market reform, Prof Kassier left an indelible mark on agricultural policy, education, and industry. His influence is not only etched in research papers and policy reports but also in today’s thriving, deregulated agricultural markets.

Fondly called “Algie” by those close to him, Prof Kassier devoted his career to bridging the gap between agricultural economic theory and practical application. His work culminated in the landmark Kassier Report, which laid the foundation for deregulating agricultural markets in the 1990s. At a time when South Africa was undergoing significant political and economic change, his leadership in policy reform helped reshape the agricultural landscape, fostering competition, efficiency, and inclusivity.

Born and raised in the German community of Wartburg, KwaZulu-Natal, his early years shaped his multilingual abilities and deep appreciation for agriculture. A gifted linguist, he was fluent in English, Afrikaans, German, and isiZulu—an ability that later enriched his teaching and engagement with students from diverse backgrounds. After earning his degrees at the University of Natal and the University of Hohenheim in Germany, he took up a position at Stellenbosch University in 1964. Within a year, he was appointed Professor and Head of the Department of Agricultural Economics, a position he held for nearly three decades. His tenure saw the department become a leading centre for agricultural economics research in Africa.

But Prof Kassier was never just an academic. He was a mentor, an innovator, and a problem solver. He supervised countless Master’s and PhD students, shaping the next generation of agricultural economists. His teachings extended beyond university walls, with hundreds of short courses and industry seminars that brought academic insights directly to farmers and agribusiness leaders. His legendary farm management and agricultural policy courses became a rite of passage for many in the sector.

Beyond the classroom, he played a pivotal role in restructuring South Africa’s agricultural marketing system. In 1992, he was tasked with leading the Committee of Inquiry into the Marketing Act, where his keen research and strategic approach played a crucial role in phasing out obsolete control boards. The resulting Agricultural Marketing Products Act of 1996 ushered in a new era of free-market agriculture, ensuring that competition, rather than regulation, drove efficiency and growth.

Even after retirement, Prof Kassier’s expertise remained in demand. He chaired multiple advisory committees, including one that ended the KWV’s monopoly over the wine industry, paving the way for a more dynamic and globally competitive sector. His impact on South African agriculture continues to be felt in anticipated and unexpected ways.

Despite his sharp intellect and high standards, Prof Kassier was known for his wit and warmth. His sense of humour, often laced with irony, made even the most serious discussions engaging. He mentored many, including the late Prof Mohammed Karaan, whom he supported as the first student of colour in the department and whose career was profoundly shaped by Kassier’s guidance.

Prof Kassier’s legacy is defined by his bold vision, relentless pursuit of reform, and unwavering commitment to excellence. His contributions helped shape an industry that continues to evolve, benefiting millions of South Africans. As we reflect on his life, we honour not only his achievements but also the values he instilled—rigour, integrity, and an unwavering commitment to progress.

The agricultural economics profession has lost a giant. Stellenbosch University has lost a cornerstone of its history. But his influence lives on in every deregulated market, every student he mentored, and the thriving agricultural sector he helped build.

The South African Society of Crop Production (SASCP), Soil Science Society of South Africa (SSSSA), and Southern African Society for Horticultural Sciences (SASHS), gathered for the annual Combined Congress 2025 (CC2025) held in Polokwane from 19th – 23rd January. The Combined Congress is a unifying platform for all members of the aforementioned societies. The event fosters a holistic understanding of sustainable agricultural practices and environmental stewardship. Each year, the congress rotates to different locations across South Africa, allowing society members to engage with diverse agricultural landscapes and regional challenges.

 The congress was held in Polokwane, Limpopo, at The Ranch Hotel for the first time. Immersed in the rich cultural heritage of Limpopo, society members engaged in discussions about the CC2025 theme: ‘Science for Commercial and Rural Development’; while making network connections in the comfort of the aircon during the summer heat. Constantly refreshed and pampered by the amenities, services, and events, the CC2025 was ideally located, which was evident in the high attendance of the event. Additionally, the locality allowed for field visits to local legends such as ZZ2, Westfalia Fruit, and Torofina Trading Post Farming. 

One of the most exciting aspects of the CC2025 was the research presentations and posters delivered by students and researchers from across South Africa. Among the standout participants were the students from Stellenbosch University (SU), who showcased their work across various disciplines. Their research not only highlighted the depth of academic excellence at the university but also underscored the critical role of science in addressing real-world challenges.

The poster sessions were a colorful maze of the latest advancements in agriculture, environmental science, and sustainability. The SU students made a significant impact with their beautiful maroon and gold posters and articulate presentations:

– Jade Andrews explored the benefits of “cover crop integration” in vegetable Conservation Agriculture systems in her poster, demonstrating how this practice can improve weed management and promote sustainable farming. Andrews also took the stage to expand on her poster by presenting the soil health and crop yield effects of the aforementioned systems. For her impressive work, Andrews received the ZZ2 Conservation Student Award.

 – Andries Le Roux delved into the pressing issue of climate change, presenting his research poster on its impacts on “canola growth and yield characteristics”. Expanding on his poster, Le Roux presented his climate work in the context of the Swartland region. His work provided valuable insights into adapting agricultural practices to a changing climate.

– Mmakwena Velicia Mabitsela presented a poster titled “The Effects of Rotational Tillage with a Deep Tine to 45 cm Depth” on Canola Productivity in the Swartland Region at SASCP. As a member of the SSSSA, she presented her findings on the nutrient stratification of the aforementioned tillage practices. Her findings highlighted the potential of innovative tillage practices to enhance crop yields and she was honored with the SSSSA Award for Best Presentation. 

– Dr. Flackson Tshuma presented his research on the effects of “tillage rotation and biostimulants” on crop productivity and the reduction of synthetic agrochemical use in dryland cropping systems. His work emphasized the importance of sustainable farming practices.

– Okamelang Shao examined “wheat cultivar responses to foliar diseases” under different fungicide spray programs, offering practical recommendations for disease management in wheat production.

– Sandra Hull focused on “genotype-environment interactions in pre-harvest sprouting of wheat”, shedding light on how genetic and environmental factors influence crop quality. Hull was center stage, presenting on this topic, and was awarded the Daan F Retief floating trophy for the best paper (40 years and younger); leading the way for young scientists. 

-Louise Bestbier presented on herbicide use in Conservation Agriculture systems. Her work sought to answer the questions posed by farmers looking to transition to more sustainable practices. She received the student award for best presentation.  

– Joshua Apples took the stage at the SASHS session, presenting his work on “improving the sustainability of blueberry production through the optimization of preharvest factors”. His research offered actionable strategies for enhancing both yield and sustainability in blueberry farming.

The research presented by the SU students was a testament to their dedication, creativity, and commitment to solving some of the most pressing challenges facing agriculture and the environment today. Stellenbosch continued to shine with additional awards given to Dr PJ Pieterse for the best paper published during 2023 SA Journal of Plant and Soil and Daniel Johannesburg Volschenk receiving the SASCP Student Award for Academic Performance (75%+).

The pre-graduation celebration on Tuesday, 25 March, was a heartfelt occasion filled with hope and gratitude as we honoured 15 transdisciplinary MSc students (Food & Nutrition Security and Sustainable Agriculture) and one PhD student. A sense of anticipation and excitement filled the room as these graduates prepared to embark on their next chapter.

Prof Gunnar Sigge and Dr Ethel Phiri, along with Prof Mbhenyane (in absentia), extended heartfelt congratulations, acknowledging the significant achievements of each student. The graduates, in turn, shared moving accounts of their academic journeys, highlighting the profound impact their studies have had on both their personal and professional lives.

The connection between food systems, food production, and our fundamental right to food was a central theme. Recognising the inherent inequalities and disparities within these systems, the programs’ emphasis on a systems approach proved invaluable. As demonstrated by the graduates, this approach has equipped them to navigate complex challenges across diverse domains, from primary production to health and nutrition.

Now poised to make a difference, many graduates are joining esteemed organisations such as UNICEF, the World Bank, and the food processing and retail sectors. Their success serves as a beacon of hope for the future.

We extend our warmest congratulations to each graduate. A special thank you also goes to the dedicated staff from the Faculty of Medicine and Health Sciences and AgriSciences, whose collaborative efforts have been instrumental in bringing this hopeful vision to life.

Sweetness hails from the small town of Alice in the Eastern Cape, where her passion for science and determination has shaped an inspiring journey of perseverance. Her drive to pursue postgraduate studies in Soil Science was sparked by her Cum Laude BSc degree from the University of Fort Hare in Alice and her first peer-reviewed publication from her final year project. As an introvert, Sweetness found it easier to express herself through writing than through speaking. Her high school English teacher, recognizing her talent for written communication, once suggested she consider a career in journalism. At the time, Sweetness didn’t believe in the idea, feeling that a career in journalism required a level of social charisma she didn’t possess. However, looking back, Sweetness now realizes that her teacher’s words were more prophetic than she could have known. While she never pursued journalism, her love of writing has always been central to her journey, helping her communicate science in ways that blend the art of writing with the power of discovery. Through her dedication to writing and communicating complex scientific concepts, Sweetness has contributed to the advancement of Soil Science, with a citation index of 5 and eight publications in peer-reviewed journals, showcasing the impact of her research and her commitment to sharing knowledge.

Sweetness’s academic journey was never without hardship. Choosing to pursue a PhD at Stellenbosch University meant leaving her extended family of five, including her precious daughter Khanya, behind. Just as she was settling into the demands of her research, COVID-19 hit, and everything changed. Her mother, the family’s sole financial provider, lost her job, placing even more pressure on Sweetness to support her loved ones while juggling her own academic pursuits. It was a daunting realization that her NRF bursary was now the main lifeline for her entire family. Yet, Sweetness found strength in this challenge, knowing that her dreams and those of her family depended on her perseverance.

With the bursary allowance not enough to sustain her family, Sweetness had no choice but to start applying for jobs. In 2021, she was offered a lecturing position at Fort Cox Agriculture and Forestry Training Institute. Initially hesitant, knowing the demands of her PhD would leave little room for additional responsibilities, she was encouraged by her supervisors to accept the offer. She learned to balance her teaching responsibilities with her research, making weekends a blur of travel between two provinces to conduct laboratory experiments, while managing the exhaustion that came with the double workload. Despite the challenges, Sweetness’s resilience never faltered.

As if that wasn’t enough, Sweetness faced a physical challenge that would further test her endurance. She suffered a knee injury that required rare surgery. Doctors explained that the injury was related to childhood trauma, a damage comparable to those sustained by athletes, which resulted in meniscus damage that could not be repaired and required arthroscopic grafting. Despite the pain and uncertainty, Sweetness shares that the achievement she celebrates today means more than the physical pain she endured. Every challenge, including this one, has made her success all the sweeter and more meaningful.

Through it all, Sweetness’s unwavering determination, combined with the guidance of her supportive mentors, enabled her to complete her PhD graduating with straight A’s and no corrections required from her examiners.

Looking back, Sweetness feels a profound sense of gratitude for the guidance and encouragement she received, particularly from her supervisors. “As a supervisor, my role is to make sure my students achieve their goals,” Prof Clarke once said to her in one of the field trips. At the time, Sweetness didn’t fully understand the depth of this statement, but in her moments of struggle, those words became a lifeline.

Today, Sweetness’s story serves as a beacon of hope for young, ambitious children who may feel that their dreams are too distant. She wants them to know that no matter what their background, with resilience, support, and the courage to chase their passions, anything is possible. As Paulo Coelho writes in The Alchemist, “When you want something, all the universe conspires in helping you to achieve it.”

The Faculty of AgriSciences remembers Ken Pringle, a dedicated entomologist, esteemed colleague, and cherished mentor, who passed away peacefully at his home in Stellenbosch on 14 January 2025, surrounded by his loved ones.

Born in Queenstown in the Eastern Cape, Ken’s passion for insects took root on his family’s livestock farm outside Tarkastad, where his fascination with dung beetles began. This early interest evolved into a lifelong commitment to entomology, culminating in an illustrious career marked by groundbreaking contributions to biological control and integrated pest management, particularly in South Africa’s fruit industry.

Ken completed his undergraduate studies at Rhodes University before earning both his master’s and doctoral degrees at Stellenbosch University. In January 1987, he joined the Department of Entomology and Nematology (now the Department of Conservation Ecology and Entomology) after working at the Agricultural Research Council. With a keen analytical mind and additional training in statistics, he tackled complex entomological challenges with precision, making a lasting impact in applied entomology.

Beyond his academic contributions, Ken was a revered mentor who trained and inspired generations of students, researchers, and industry professionals. His guidance was sought by fruit growers, researchers, and technical advisors alike, reflecting the depth of his expertise and the respect he commanded.

More than his professional achievements, Ken was known for his sharp wit, insightful conversations, and generous spirit. His presence enlivened coffee breaks and discussions, where he eagerly shared his thoughts on science, life, and the world around him. Those who knew him fondly remembered his humour, warmth, and unwavering passion for his work and his family.

Ken was laid to rest at St Mark’s Catholic Church in Stellenbosch on 24 January 2025. He is survived by his wife, Bernadette, his children Gordon, John, and Jenny, his grandchildren Thomas and Emily, and his beloved cats, Freddy and Molly.

His legacy in entomology and in the lives he touched endures. We honour his memory and the profound contributions he made to our faculty and beyond.

Stellenbosch University boasts the oldest Agricultural Economics Department in South Africa. The Department was established in 1925 with Prof J.F.W. Grosskopf as the first Chair. Since then, the Department has graduated just over 2 000 students with bachelor’s degrees, the first awarded in 1926, and about 400 students with postgraduate degrees, the first awarded in 1930.Some of our era’s best agricultural economists have helped shape the Department and Agricultural Economics discipline over the past century, including Profs F.R. Tomlinson, W.E. Kassier, P.H. Spies, N. Vink, M. Karaan, and T. E. Kleynhans.

The evolution of the Agricultural Economics discipline in South Africa has its roots in the contributions of Prof Tomlinson, particularly on the interplay between macro-and microeconomic analysis in understanding and solving economic dilemmas in the agricultural industry. A strong foundation that we as a department are building when we develop the next generation of leaders in the agricultural sector to face the challenges of tomorrow.

Some of the key strategic actions we have taken to prepare ourselves for the responsibility of developing our future leaders are a re-evaluation of our curriculum, the memorandum of understanding with the Bureau for Food and Agricultural Policy (BFAP), the appointment of industry partners as research fellows in the Department, the inauguration of the Stellenbosch AgroInformatics Initiative at our Department, and the establishment of a formal postgraduate committee to represent our Department’s postgraduate students, and foster connections with our industry network.

The Department’s centenary is as much a celebration of the achievements of our alumni and industry partners as it is of our own legacy. Together, we have made a lasting impact, and together, we can shape a sustainable future for agriculture. We warmly invite our alumni, colleagues, and public and private sector partners to join us throughout 2025 as we commemorate this historic occasion under the theme 100 Years of Empowering Agriculture through Economics.

Your continued support ensures that the next chapter of our journey is as impactful as the last. Let’s celebrate this centenary together!
