Building leaders to tackle hunger and malnutrition across Africa by Willie du Plessis MOIRA MULLER Thu, 11/13/2025 - 09:11

For more than two decades, the African Nutrition Leadership Programme (ANLP) of the North-West University (NWU) has been shaping the future of nutrition leadership on the continent. Since its first programme in 2002, this flagship 10-day residential initiative, hosted annually at the NWU, has developed over 500 professionals from more than 40 African countries. This year alone this flagship programme will reach close to 50 professionals from 10 African countries.

Participants represent a wide range of sectors, including academia, non-governmental organisations and government departments, all united by a shared commitment to improving nutrition and public health across Africa.

A powerful network of change-makers

According to Dr Christine Taljaard-Krugell, the ANLP has built “an active, strong and deeply collaborative” network of professionals. This is one of the most effective platforms for driving change in nutrition across the continent.
The programme offers far more than a conventional training course. It is an intensive learning journey that combines reflection, teamwork and self-discovery. Participants are encouraged to “lead from where they stand”, developing the confidence and insight needed to influence change in their own organisations and communities.

Resilience and renewal

In 2019, the ANLP marked a major milestone by hosting two full 10-day programmes for the first time, responding to a growing demand for leadership development in the nutrition field. That momentum was soon tested by the COVID-19 pandemic, which challenged the programme to adapt and maintain its sense of connection.

Despite restrictions, a 2020 programme took place successfully with 24 participants (five men and 19 women) from 11 countries, even as some faced travel disruptions in South Africa and at Kenyatta Airport in Nairobi. The 2022 cohort was kept small, with 13 participants from nine countries. The programme returned to full strength in 2024, welcoming 24 participants (eight men and 16 women) from eight countries.

Participants consistently describe their ANLP experience as “transformative” and “life-changing”, a reflection of the continued focus of the programme on self-leadership, teamwork and practical impact.

Expanding reach and influence

Interest in the ANLP continues to grow, with over 400 applications having been received for the 2025 and 2026 programmes. Each programme accommodates around 30 participants, and to meet the increasing demand, two sessions will again be hosted in both years. A full evaluation is also underway to assess long-term impact and guide future development.

In addition, an online NWU short course, Leadership essentials in public health, led by Dr Cornelia Conradie, has been developed to expand leadership training in public health and strengthen progress toward the sustainable development goals (SDGs).

As Prof. Johann Jerling, director of the ANLP, notes: “Leading change in nutrition is, and will remain, central to what we do – it is essential to addressing our continent’s most pressing needs.”

Dr Monray Williams is helping to lead Africa’s virology charge by Bertie Jacobs MARELIZE SANTANA Tue, 11/11/2025 - 10:04

The battle against HIV in sub-Saharan Africa has always been as much about systems and science as about the virus itself. Antiretroviral therapy has turned what was once a death sentence into a manageable condition.

Yet, as Dr Monray Williams of the North-West University (NWU) cautions, “millions of people still face barriers to prevention and treatment. Poverty, limited healthcare infrastructure, and social stigma continue to shape who gets care and who does not.”

The paradox is stark: Africa remains the global epicentre of HIV, yet it is also becoming a nerve centre of virological innovation. For decades, most HIV science has been dominated by research from the global North, focusing on the viral subtype B common in Europe and North America.

In southern Africa, however, subtype C – the continent’s dominant strain – tells a different story. “Even with significant investment,” says Dr Williams, “our outcomes remain uneven because proper management and sustainable implementation strategies have not always followed the funding.”

Dr Williams, a virologist and molecular neurobiologist, leads a research group at the NWU that seeks to untangle this imbalance both scientifically and structurally. His work examines the pathogenesis and neuropathogenesis of viral diseases, combining in silico analysis, in vitro experiments, and clinical studies.

Recently awarded a prestigious Fulbright Fellowship to continue his research in the United States, he represents a new generation of African scientists who are redefining the global research landscape from within.

“Our investigations explore how HIV-1 viral proteins, particularly in subtype C infections, affect inflammation, metabolism, and cardiovascular risk in both children and adults living with HIV,” he explains.

This focus on sequence variations in viral proteins such as Tat, Vpr, and Vif is more than academic curiosity. It goes to the heart of understanding why neurological complications persist even when viral loads are suppressed.

“We analyse cerebrospinal fluid and blood samples to identify biomarkers that can predict or monitor neurological complications,” says Dr Williams. “By identifying these molecular signatures, our goal is to support earlier diagnosis, improve treatment monitoring, and inform the development of therapies better suited to African populations.”

The intersection between virology and neurobiology is fertile ground. HIV does not merely weaken the immune system, it can also invade the brain, leading to cognitive impairment and neuroinflammation.

“Virology and molecular neurobiology are distinct fields of study,” Dr Williams explains, “but they intersect when studying how viruses invade neurons, alter neuronal function, and cause neurological damage.” Understanding that overlap, he argues, is key to treating a generation of patients living longer with HIV but still battling its hidden neurological consequences.

Progress, however, is not only about lab results, it is also about leadership and local innovation. Across the continent, African-led initiatives are reshaping HIV surveillance and care. Community health workers deliver treatment where hospitals cannot; mobile health platforms track patients and send medication reminders; and traditional healers, often trusted where doctors are not, play a vital role in reducing stigma and encouraging testing.

“When African-led initiatives are supported by strong governance and thoughtful investment strategies,” says Dr Williams, “they can reach millions of people and transform lives.”

That combination of local trust and scientific rigour is paying off. Recent clinical trials of lenacapavir – a twice-yearly injectable drug – reported zero new infections among women in South Africa and Uganda. Endorsed by the World Health Organization, it could revolutionise prevention by overcoming the adherence challenges that have plagued daily medication.

Meanwhile, African scientists such as Prof Thumbi Ndung’u, under networks such as the Sub-Saharan African Network for TB/HIV Research Excellence, are driving cure research and integrated care models that connect HIV treatment with tuberculosis, diabetes, and mental health care.

For Dr Williams, these advances signal a continental shift: “Africa is not just a site for research, it is a source of it.” But he is frank about the challenges. “The real progress against HIV in Africa will not come from science alone but from how we manage and invest in that science,” he says. Billions have been poured into programmes, yet results vary widely. “This is often not because of a lack of knowledge or innovation, but because of weak management structures, fragmented implementation, and short-term planning.”

His solution is unapologetically practical: sustained investment in research infrastructure, education, and scientific leadership paired with transparent governance and accountability. “Africa already has an extraordinary pool of researchers who are world leaders in virology, immunology, and neuroHIV science,” he says. “What we need now is the confidence and coordination to turn this knowledge into tangible impact.”

That call for confidence is more than rhetoric. Local research on subtype C is already improving diagnostic accuracy and treatment design. “When we generate our own data, build our own technology, and train our own scientists, we produce tools that reflect the real biological diversity and health realities of our continent,” says Dr Williams. “This is how we move from dependency to leadership in the global HIV response.”

As Africa’s laboratories and clinics grow more sophisticated, so too does its scientific voice. The continent that once bore the heaviest burden of the epidemic is now shaping the science to end it. “If we can align our resources, strengthen our health systems, and invest in people,” Dr Williams concludes, “then the vision of ending the HIV epidemic in Africa is within reach.”

In his quiet, empirical way, he represents what the future of global health could look like: rigorous, rooted, and unashamedly African.

Study develops health-promotion strategies for caregivers of HIV/AIDS orphans by Mafumane Tlhapi BELINDA BANTHAM Thu, 11/06/2025 - 15:19

Caregivers of children orphaned by HIV/AIDS carry responsibilities that shape family stability and community support. A new study has produced health-promotion strategies to strengthen their ability to care and sustain their own well-being.

Led by Dr Boitumelo Joy Molato, a PhD graduate from the North-West University (NWU), the study was conducted in the Ngaka Modiri Molema District in North West. Titled “Health promotion strategies to improve health and well-being of caregivers of children orphaned by HIV/AIDS”, it explored the lived experiences of caregivers and the support systems around them.

“We sought to understand the realities of caregivers of HIV/AIDS orphans and how those realities affect their health and capacity to care,” said Dr Molato. “Caregivers are central to the lives of these children, and their support structure needs to be clear and strong.”

The study used a qualitative design and took place in three phases. Thirteen individual interviews were held with caregivers, and five focus groups were conducted with 27 professional nurses who serve as outreach team leaders.

Findings showed three key challenges: lack of support for caregivers, behavioural issues among orphans, and psychosocial distress. Coping mechanisms identified included support from others, religious practices, and access to social services. Outreach team leaders contributed through home visits, multidisciplinary referrals, and support groups.

“Caregivers expressed a need for guidance, emotional backup and structured assistance,” Dr Molato explained. “Their voices shaped the strategies we developed.”

A conceptual framework guided the creation of health-promotion strategies, which were validated by seven experts through the e-Delphi technique.

“The strategies focus on building better support for caregivers so they can continue their role,” she added. “Validation ensured feasibility and relevance.”

The research offers guidance for health professionals and policymakers working in communities affected by HIV/AIDS. It places focus on strengthening caregiver well-being alongside child support needs.

“Caregivers do not work alone. With structured support, their resilience grows, and children receive stable care,” Dr Molato concluded.

Dr Boitumelo Joy Molato’s research aims to support caregivers of children orphaned by HIV/AIDS.

NWU Research Paper featured in Institute of Physics collection by Steve Maphakathe BELINDA BANTHAM Wed, 11/05/2025 - 12:29

After long days of teaching English in South Korea, Marcel van der Westhuizen would often find himself pondering the biggest questions imaginable: How will the universe ultimately end? His persistence and curiosity have now paid off.

The Institute of Physics (IOP) has published a special collection of papers featuring the research paper he co-authored with his supervisor Prof Amare Abebe, director of the Centre for Space Research at the North-West University (NWU). This collection celebrates significant research published as a result of South Africa’s transformative agreement in 2024, which aims to change publishing from subscription-based models to open access.

Their paper, ‘Interacting dark energy: clarifying the cosmological implications and viability’ explores a “non-gravitational interaction” between dark matter and dark energy.

“Our research looks at a non-gravitational interaction between two dark components and how this could lead to strange consequences, such as negative energies and even the universe ending in a future ‘big rip’,” Marcel explains.

He assures us that this scenario is still billions of years away and that it is just one of many possible scenarios.

For Prof Abebe, however, the value is more profound. “At a deeper level, this work also speaks to a fundamental aspect of what it means to be human: our innate curiosity and desire to understand the world around us," he reflects.

“Even when exploring concepts as distant as the ultimate fate of the cosmos, we are also trying to understand ourselves and our place within it.”

Identifying and solving problems: why it matters

The paper’s major breakthrough was identifying and solving significant issues with existing “interacting dark energy” models. They discovered that many established models require the existence of “negative energy,” which is a conceptually difficult idea.

“We found that this negative energy problem only occurs when dark matter decays into dark energy. However, this can be avoided if the decay is from dark energy to dark matter, which solves other problems too,” Marcel explains.

Although exploring the fate of the universe may seem abstract, it is important on Earth. According to Marcel, this kind of theoretical work elevates South Africa’s status in the global scientific community, leading to international collaborations and funding for major projects such as the Square Kilometre Array (SKA) in the Karoo.

“These science projects help to create jobs and develop South Africa’s infrastructure. Furthermore, they create opportunities for the next generation of students to work with world leaders and gain invaluable experience,” he adds.

Proud Moment

Marcel, who is currently pursuing his PhD, was initially taken aback by the news of this recognition. “I was not too sure about the significance of the selection,” he admits. “I then forwarded the email to my supervisor, Prof Amare, who told me that I should be proud.”

Prof Abebe says that this selection is an official stamp of approval on work that he already knew was exceptional. “The work was getting rapid citations, having been cited more than 45 times by major publications in the field in just over a year. This demonstrates the impact that the publication has had, and I am proud of Marcel’s excellent work on this. Official recognition from the publisher made me even prouder,” says Prof Abebe.

This paper has become personally significant for Marcel, as it symbolises an important turning point in his life and career.

“This was the first article I ever wrote. I worked on it over several months, late at night, after full days of teaching English in South Korea. When the first citations came in, it felt like validation that I had made the right choice to return to South Africa and pursue a PhD. This now feels like further confirmation that I made the correct decision to come back to research.”

Prof Abebe also sees a bright future ahead. “Marcel has published four follow-up articles since he started his PhD studies this year, and all of them are already being cited. This shows the bright academic future that awaits him, and I have no doubt that he will make many exciting contributions to the field in the years ahead.” Click the following link to access their full paper Interacting dark energy: clarifying the cosmological implications and viability

Cannabis tourism raises interest In Mahikeng community – and Portugal BELINDA BANTHAM Fri, 10/31/2025 - 10:06

By Gofaone Motsamai

When tourism researcher Dr Jean Manaliyo began asking people in Mahikeng what they knew about cannabis tourism, many were curious about how it could shape their community and economy. That curiosity has now taken his research across borders.

The North-West University (NWU) researcher will present his paper titled “Community perception towards cannabis tourism and socio-economic impacts in Mahikeng, South Africa” at a conference hosted by the University of Algarve in Portugal from 12 to 14 November 2025.

His work has been accepted for presentation and publication, and he will attend the conference in person.

“The study focuses on community knowledge and perceptions of cannabis tourism in Mahikeng,” says Dr Manaliyo, who is from the School of Tourism Management and Tourism Research in Economic Environs and Society (TREES). “There are growing calls for the South African government to legalise and decriminalise the use of cannabis, not only for medicinal use but also for recreational purposes, as a tourism product.”

One of the key findings of his study is that participants held differing views on the legalisation of cannabis. Some participants supported its legalisation, arguing that cannabis tourism could bring economic benefits, create jobs, and generate revenue from tourists.

Those opposed to legalisation argued that cannabis tourism could lead to an increase in crime. However, others suggested that, like alcohol, cannabis could be legalised under certain restrictions to ensure proper control. In addition, some participants noted that cannabis is used for medical purposes and as an energy booster.

A multi-billion market in some countries

In other parts of the world cannabis is already part of tourism activities, Dr Manaliyo says.

“In the USA, the Netherlands and Canada, people travel just to consume cannabis. These countries have facilities where visitors gather to consume cannabis, have fun and then go back to their countries,” he said. “The cannabis market is worth more than USD 20 billion, which shows its potential for tourism development.”

Dr Manaliyo says his study was driven by the growing debate around the possible economic and social effects of cannabis legalisation. “Some provinces like the Eastern Cape and KwaZulu-Natal already have people who grow cannabis. The government could tap into this and formalise it to create jobs and generate revenue.”

His research involved community members, traditional leaders and the police. He obtained ethics clearance from the Economic and Management Sciences Research Ethics Committee, the NWU and permission from Research Department in the South African Police Service before starting his fieldwork.

As his research findings show, the overall sentiment in the groups who participated in his study was positive, indicating that cannabis tourism could make a real impact on local economies.

Researcher studies traditional plants for natural pest control by Phenyo Mokgothu BELINDA BANTHAM Fri, 10/31/2025 - 09:27

When farmers face pests that damage their crops, many turn to chemical sprays. They often do not realise that indigenous plant-based practices can protect crops naturally, and that pest-control solutions already exist within traditional farming knowledge.

The use of chemicals is one of the common ways of managing pests. However, these chemicals have negative effects on the environment, are expensive, and often unaffordable for small-scale farmers.

Yet, we have knowledge that was applied for centuries by local farmers to manage pests. Despite the existence of this alternative, we currently have limited records of these plants and how they are applied. In addition, evidence on how these plants exert their effects is often lacking.

One researcher who is bringing this knowledge to light is Dr Kutullo Nick Shai from the North-West University’s (NWU’s) Indigenous Knowledge Systems (IKS) Centre at the Mahikeng Campus.

Through research funding from the National Department of Agriculture via Agricultural Research Council Pretoria and National Research Foundation, the project was supported from 2022 to 2025.

Dr Shai’s project on IKS systems of plants used for crop protection, focuses on identifying plants that smallholder farmers use to control pests and diseases.

The research revealed that a variety of locally known plants contain natural compounds that help manage crop infections. Extracts from Eucalyptus diversicolor, commonly known as the Karri tree, Dichrostachys cinerea, commonly known as Sickle bush, and Manihot esculenta, commonly known as Cassava, were found to have strong antifungal properties that can inhibit harmful fungi affecting maize and other crops.

“These plants demonstrated measurable antifungal activity,” Dr Shai explains. “Their bioactive compounds could support eco-friendly pest control approaches.”

Natural solutions are healthier

He says overreliance on chemical pesticides has led to major environmental and economic concerns. “Prolonged use of synthetic chemicals harms soil and water quality and can make pests more resistant. Natural plant-based solutions can reduce these risks and support healthier farming systems.”

Dr Shai notes that indigenous knowledge plays a crucial role in understanding local ecosystems. “Communities have developed their farming knowledge through experience and observation. They know which plants work best under certain conditions. That wisdom is valuable and deserves recognition.”

By analysing the biological effectiveness of traditional plants, the study bridges local experience and modern science. “Combining scientific testing with what farmers

already know allows us to identify plants that can be developed further into safe and affordable pest control products,” Dr Shai says.

He believes this approach could strengthen food security while reducing pressure on the environment. “Farmers often face crop losses from pests and diseases. If they can use natural methods that are accessible and affordable, it benefits both farming communities and the environment.”

Dr Shai says further work will focus on identifying the specific chemical compounds responsible for the antifungal activity found in these plants. “Understanding how these compounds work can help in developing natural products for agricultural use.”

His research shows the value of integrating traditional wisdom with modern science to create sustainable agricultural solutions. “The knowledge of farmers is not outdated,” Dr Shai concludes. “It remains an essential part of finding answers to current challenges in food production.”

Doctoral candidate takes indigenous knowledge research to Berlin by Phenyo Mokgothu BELINDA BANTHAM Mon, 10/27/2025 - 11:15

In a rapidly warming world, Africa has much to teach about harnessing indigenous knowledge systems (IKS) for global health resilience and trauma risk reduction.

Diane Thelma Molokwa, a doctoral candidate at the IKS Centre on the North-West University’s (NWU’s) Mahikeng Campus, demonstrated this when she participated at the 7th International Young Researchers' Symposium on Global Health held in Berlin, Germany.

The symposium, hosted by Akkon University Institute for Research in International Assistance, took place on 11 and 12 October 2025 and was followed by the World Health Summit from 12 to 14 October.

Diane was part of a South African research delegation that included Dr Mayashree Chinsamy and Prof Hassan Kaya from the African Institute in IKS at the University of KwaZulu-Natal. They presented two research posters on IKS and global health resilience.

The first poster examined the integration of IKS into contemporary disaster management for trauma risk reduction, management and resilience. It showed how cultural and ecological knowledge specific to African communities can enhance disaster trauma management through youth-led digital innovation, and also highlighted the role of gender intersectionality and frontier technologies in strengthening inclusive disaster resilience strategies.

The second presentation was on the global relevance of African traditional mental healthcare systems in disaster risk reduction, management and resilience. This poster focused on the role of young researchers using digital tools to revitalise indigenous mental healthcare systems.

The research aligns with global frameworks addressing climate justice, environmental health and mental well-being.

“The symposium created a space for knowledge exchange and collaboration on how IK can contribute to sustainable and inclusive health systems,” says Diane. “It also affirmed the importance of integrating indigenous perspectives in addressing global health challenges.”

She adds that participation in the symposium and the World Health Summit strengthened opportunities for future partnerships between African research institutions and international networks.

The North-West University (NWU) continues to build on its reputation as a globally competitive and innovative institution, maintaining its position among the world’s leading universities in the latest Times Higher Education (THE) World University Rankings. This achievement reaffirms the standing of the NWU locally and internationally and highlights its consistent pursuit of academic and research excellence. The new strategy of the NWU, Taking the NWU forward: 2024 and beyond, is firmly guiding the institution in its pursuit of distinction.

THE published the 2026 edition of the THE World University Rankings on 9 October. It placed the NWU in the 801 to 1 000 category out of 2 191 participating universities worldwide. The university achieved a total score in the 35,5 to 38,9 range and ranks eighth among 13 South African universities. This matches the NWU’s 2025 performance, when it was also placed in the same global category and national position, underscoring the steady progress and sustained excellence of the university. It is a great achievement for the NWU to keep its ranking in the same categories, considering that there was an increase of 99 institutions compared to the total of the previous year.

The NWU performed particularly well in the international outlook pillar, reflecting its growing profile as a globally engaged university committed to excellence and societal relevance. This pillar measures international co-authorship, international staff and student ratios, and opportunities for study abroad. Once again, international outlook was the university’s strongest area of performance, with its overall score improving from the previous year’s 34,5 to 38,1 range.

Strategic focus drives global impact

The strategy for the university for 2024 and beyond is anchored in four key priorities: results-oriented leadership, systems thinking and policy fluency, private-public value co-creation, and digital and green economy enablement. These priorities strengthen the focus of the NWU on globally relevant, sustainable solutions and its commitment to creating meaningful impact.

Examples of initiatives aligned with this strategy include the establishment and proposed establishment of three future-fit academic schools – the Desmond Tutu School of Medicine, the School of Mines and Mining Engineering, and the School of Veterinary Sciences. These and other innovative cross-sectoral projects reflect the strategic framework of the university, which emphasises internationalisation, partnerships and societal impact.

Prof Linda du Plessis, senior deputy vice-chancellor for teaching and learning, says the consistent success of the NWU in international rankings reflects the strength of its strategy and the collective efforts of its academics, researchers and professional staff.

Innovative research delivers eco-friendly, cost-effective feed solution for beef cattle by Oscar Mosiane BELINDA BANTHAM Mon, 09/22/2025 - 19:22

The North-West University (NWU) is proud to celebrate the recent graduation of Dr Nozipho Phila Gamedze, who received her PhD on 16 July 2025. Her research marks a significant contribution to both sustainable agriculture and nanotechnology, showcasing the power of interdisciplinary science rooted in African innovation.

Her thesis, entitled “Bio-nanotechnology applications in beef cattle nutrition: quenching perilous effects of antinutritional factors in mucuna seed meal-supplemented diets” investigated the efficacy of green versus conventional zinc oxide (ZnO) nanoparticles in enhancing the nutritional value of the seeds of Mucuna pruriens utilis, a nutrient-rich yet underutilised legume indigenous to Southern Africa.

The seeds of the Mucuna legume boast high levels of energy, protein (amino acids), minerals, and essential fatty acids. They also possess hypoglycemic, hypolipidemic, hypo-cholesterolemic and anabolic properties. However, their usage as animal feed is constrained by the occurrence of high fibre content and toxic substances, primarily a noxious amino acid called 3,4-dihydroxy-L-phenylalanine (L-DOPA), consumption of which reduces appetite and growth.

For this reason, Dr Gamedze employed the innovative strategy of nanoparticle pre-treatment of the seeds to jointly resolve the problems of high fibre content and toxic substances so that they could be used as beef cattle feed.

Dr Gamedze developed the green-synthesized ZnO nanoparticles in the subject group Chemistry using the aqueous extract of Mucuna seeds. In a pioneering cross-disciplinary study, she tested the nutritional utility of these green nanomaterials in improving the diets of beef cattle. By integrating both in vitro and in vivo experimental systems, she demonstrated that the plant-based ZnO nanoparticles could enhance feed efficiency and animal health when combined with Mucuna seed meal-based feed as a cost-effective alternative to conventional protein sources like soybean meal, cottonseed cake and sunflower seed cake.

Bringing diverse perspectives to her work, Dr Gamedze’s PhD was supervised by a dynamic team of experts including Dr Doctor Mziwenkosi Nhlanhla Mthiyane as lead supervisor and an animal nutritionist, Prof Sydney Mavengahama as expert in agronomy and legume utilisation, and Prof Damian Chinedu Onwudiwe, an expert in nanobiotechnology and inorganic chemistry.

Their collective mentorship enabled Dr Gamedze to bridge the gap between chemistry, agriculture and biological systems, making her work a true reflection of the NWU’s commitment to transdisciplinary research for sustainable development.

A green alternative to conventional nanomaterials and animal feed

The study compared the performance of Dr Gamedze’s biosynthesised ZnO nanoparticles with commercially available conventional nanomaterial counterparts, highlighting the environmental advantages, safety profile, and improved functionality of the green alternative.

In an in vitro system, both the green and conventional nanomaterials increased the digestibility of Mucuna seed meal, with 20 mg/kg of the phytogenic nanomaterials inducing greater effects. However, in an in vivo system with Bonsmara steers fed a high (20%) dietary level of the seed meal, the phytogenic nanomaterials deteriorated the detrimental effects of the legume on growth, carcass traits, and some haematological responses while the conventional nanomaterials abrogated the perilous effects. These findings highlighted the danger of solely relying on research outcomes achieved using in vitro systems without further validation using in vivo systems.

“This research shows how indigenous knowledge and advanced science can come together to solve real-world problems,” said Dr Gamedze. “We’re not only reducing feed costs for farmers, but also using safe, sustainable technologies that protect the environment and improve animal nutrition.”

The combination of nanotechnology and indigenous legumes could reduce the cost of livestock production while addressing concerns about food security, sustainability, and access to affordable animal protein in rural and emerging farming contexts.

Impact and future directions

Dr Gamedze’s findings have the potential to:

· Lower the cost of animal feed production, especially for small-scale and emerging farmers.

· Promote the cultivation and use of Mucuna pruriens utilis, an underutilized yet valuable local crop.

· Encourage the use of green nanotechnology in agriculture and veterinary science.

· Contribute to environmental sustainability by reducing reliance on synthetic feed additives and imported protein sources.

As she looks to the future, Dr Gamedze plans to continue her research and commercialise elements of her work in collaboration with agricultural stakeholders.

“We have the science, the resources, and the indigenous knowledge to solve our own problems. This research is a step toward food sovereignty and scientific excellence driven from within the continent,” she said.

Building bridges beyond graduation: research highlights power of relationship marketing in fostering loyal alumni by Oscar Mosiane BELINDA BANTHAM Fri, 09/19/2025 - 12:51

At a time when the role of higher-education institutions (HEIs) is increasingly tied to their relevance and impact in society, alumni have emerged as one of the most vital stakeholders in driving institutional success and community development.

Groundbreaking research by Dr Anna Maria Matthysen, titled “Relationship marketing as foundation for fostering loyal alumni: the case of a TVET college in the Western Cape”, offers a strategic lens through which HEIs can reimagine alumni engagement – not as an afterthought, but as a foundational element of institutional growth and societal contribution.

Promoted by Prof M Potgieter and co-promoted by Prof AM Litheko, the study is a timely and significant contribution to the field of higher-education management. Its primary objective was to develop a framework that HEI management can implement to cultivate strong, lasting bonds with their alumni, thereby enhancing their sustained involvement in community development.

Relationship marketing: a strategic imperative for HEIs

At the heart of Dr Matthysen’s research lies the principle of relationship marketing – a strategic approach focused on building long-term, trust-based relationships rather than transactional interactions. The findings emphasise that this approach is not just relevant but essential for HEIs seeking to strengthen alumni engagement and foster a culture of lifelong affiliation.

“Relationship marketing provides the foundational framework for HEIs to develop, strengthen and sustain meaningful relationships with their alumni,” says Dr Matthysen. “It enables institutions to shift from periodic contact to ongoing connection, ensuring alumni feel valued, heard and involved.”

From graduation to lifelong engagement

The study, set within the context of a technical and vocational education and training (TVET) college in the Western Cape, has broad applicability across higher-education institutions. It underscores that alumni loyalty does not occur by default – it must be intentionally cultivated through sustained relationship-building efforts that begin well before graduation and continue long afterwards.

The proposed framework in the research encourages HEIs to adopt an integrated strategy that includes consistent and personalised communication, opportunities for alumni to contribute meaningfully to institutional goals, recognition of alumni achievements, and collaborative community development initiatives.

Such efforts not only strengthen the alumni-institution bond but also position alumni as active participants in societal transformation. This is something that is particularly aligned with the vision of the North-West University (NWU) of being locally engaged and globally relevant.

Alumni as partners in progress

The research affirms that alumni are not just former students – they are enduring ambassadors and co-creators of the legacy of an institution. Their loyalty, insights, networks and contributions can significantly impact areas such as student mentorship, fundraising, curriculum relevance and community upliftment.

Dr Matthysen’s study calls on HEIs to view alumni not as passive recipients of communication but as partners in progress, capable of co-shaping the future of education and development.

A call to action for HEIs

The implications of this research resonate strongly with the strategic goals of the NWU, particularly in strengthening alumni relations, stakeholder engagement and social impact. By embedding relationship marketing principles into alumni engagement strategies, HEIs can build a culture of trust, reciprocity and lifelong connection. This culture is one where alumni proudly remain part of their institutional family long after receiving their qualifications.

This study serves as both a blueprint and a call to action for universities and colleges across South Africa and beyond: to move from transactional outreach to transformational relationships for the benefit of the institution, the alumni and the broader community.
