| Prof Joel Modiri delivers SU's 7th Africa Day Lecture | https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=11316 | | Prof Joel Modiri delivers SU's 7th Africa Day Lecture | Desmond Thompson | <p>A powerful and sobering lecture by legal scholar and public intellectual Prof Joel Modiri headlined Stellenbosch University's 7th Annual Africa Day Lecture on 21 May 2025. The event at the SU Museum drew a large and diverse audience of students, academics, diplomats and members of the public.<br></p><p><strong>'Africa's time is now'</strong></p><p>Introducing the event – the first Africa Day Lecture since his appointment in April – SU Rector and Vice-Chancellor Prof Deresh Ramjugernath spoke of the role universities must play in shaping a just, inclusive and collaborative future. He described SU's commitment to becoming “not only <em>a</em> university in Africa", but one that is “proudly and purposefully <em>for</em> Africa".</p><p>“That means moving beyond old paradigms of prestige and towards a future where excellence is measured by impact, inclusion, and innovation. It means producing research that matters – to rural communities, to informal economies, to climate-vulnerable regions, to young people carving out a future in a rapidly changing world," he added.</p><p>“It also means confronting our own institutional past with honesty. The road to transformation is not paved with declarations but with daily decisions – about who teaches, who leads, who feels that they belong. Our transformation journey must be grounded in empathy, equity, and an unwavering belief in the brilliance of African minds."</p><p><strong>Thought-provoking</strong></p><p>As Modiri took to the stage, he said: “I hope that the provocations I'm going to offer is going to be of some value."</p><p>The acting Deputy Dean: Teaching and Learning in the University of Pretoria's Faculty of Law and Head of its Department of Jurisprudence, Modiri delivered a lecture that spanned history, law, philosophy and politics. He challenged the audience to reckon with the enduring legacies of colonialism and apartheid – and to reflect on the unfinished project of liberation.</p><p><strong>'Three deaths'</strong></p><p>Framing his lecture around what he called the “three deaths" of Steve Biko, whom he described as the “great Prophet Intellectual" of the Black Consciousness Movement, Modiri said he would “attempt to disturb our inclination towards closure and happy endings, because there do not seem to be any".</p><p>Biko's “first death", he explained, was his brutal killing in police custody in 1977. His “second death" came nearly two decades later, in the Constitutional Court's 1996 judgment upholding the Truth and Reconciliation Commission's amnesty provisions. The decision denied Biko's family – and many others – the legal redress they had sought.</p><p>Biko's “third death", Modiri argued, is unfolding today – in what he called a time of “Trump in Africa, genocide and nihilism". He described the present as a moment of global authoritarianism, local Afrophobia, ecological collapse and the erosion of democratic and educational ideals.</p><p>That is why Biko's legacy, he stressed, endures as a haunting and urgent call. His writings continue to confront us with the irreparable nature of apartheid's violence – and with the moral demand for justice.<br></p><p>Modiri reminded the audience that Biko wrote: “Black people must rally together around the cause of their oppression … to rid themselves of the shackles that bind them to perpetual servitude."</p><p>He was sharply critical of South Africa's negotiated settlement in the early 1990s and the compromises that underpinned it. “By placing compromise at the heart of political and legal change," he said, “the advent of constitutional democracy would paradoxically mutate into a stubborn and frustrating changelessness."</p><p>The result, he said, is that South Africa remains caught in the past – “like yesterday" – with deeply entrenched racial and economic hierarchies left largely untouched. “This is why we are where we are," he told the audience.</p><p>Modiri emphasised that the mere inclusion of black people – in government, on street names, in official narratives – had not led to real liberation. “Black people have only the symbols of freedom," he said. “But not the essence of freedom. And so, all in South Africa remain unfree."</p><p>He also called on white South Africans to reject the notion that historical redress is a form of vengeance. True liberation, he argued, would benefit everyone – but only if it included a meaningful reckoning with the past.</p><p>“We should remember," Modiri said, “that by posing the aspiration for a true humanity against the racialism of colonial apartheid, Biko points not only to the devastation wreaked on the lives of black people, but also to the brokenness in the humanity and humaneness of white people, evidenced by their historically sanctioned indifference to the racial suffering of others and their misrecognition of how their social position has been secured through centuries of violence and subjugation."</p><p><strong>Global context</strong></p><p>Situating South Africa's crisis within a broader global pattern, Modiri warned against the resurgence of white supremacy and the rightward shift in global politics – trends that reinforce historical hierarchies under new guises. </p><p>This global entrenchment of inequality, Modiri suggested, exposes the limits of symbolic transformation and the urgent need to confront the enduring systems of racial and economic power.</p><p><strong>Call to action</strong></p><p>“There is," Modiri conceded, “no easy way out of our present historical condition." But, he added, “if such an undertaking feels impossible, feels dangerous, feels demanding and unceasing – that may be because it is."</p><p>He nonetheless closed not with despair, but with a challenge to his audience: “We must reclaim historical possibility against the past. We must confront and name the violence. We must fashion radically different ways of living together."</p><p><em>Africa Day, celebrated annually on 25 May, commemorates the founding of the Organisation of African Unity (OAU) in 1963 – a milestone in the continent's liberation and unity struggles. In 2002, the OAU evolved into the African Union (AU), reflecting the continent's continued commitment to integration, development and collective progress.</em></p><p><em>SU's 7th Annual Africa Day Lecture was hosted by the Rector and Vice-Chancellor and coordinated by the Centre for the Study of the Afterlife of Violence and the Reparative Quest (AVReQ), in partnership with the University's Centre for the Advancement of Social Impact and Transformation (CASIT) and the Centre for Collaboration in Africa (a unit of SU International).</em></p><p>* * * *</p><p><em>Desmond Thompson is a freelance journalist.</em></p><p><strong><em>CAPTION: </em></strong><em>From left, SU VC Prof Deresh Ramjugernath, AVReQ Director Prof Pumla Gobodo-Madikizela, and UP's Prof Joel Modiri, who delivered SU's 7th Annual Africa Day Lecture on 21 May 2025.

| SU takes bull by the horns with study on regenerative wine farming | https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=11308 | | SU takes bull by the horns with study on regenerative wine farming | Desmond Thompson | <p>Next time you drive along Bottelary Road outside Stellenbosch, keep an eye out: you may just catch a glimpse of cattle grazing among the vineyard rows at <a href="https://hartenbergestate.com/">Hartenberg Wine Estate</a>. It may be an unusual sight, but it reflects an important shift in global wine farming.</p><p>The animals are part of <a href="https://winetechlibrary.co.za/regenwine-regen/">ReGenWine</a>, a three-year research project led by <a href="/english/">Stellenbosch University</a> (SU) that is helping to bring greater scientific rigour to the growing international trend of regenerative viticulture.</p><p>The project, funded by <a href="https://sawine.co.za/">South Africa Wine</a>, is one of the most comprehensive efforts to date to test the potential of regenerative viticulture in practice.</p><p><strong>Putting claims to the test</strong></p><p>In agriculture worldwide, the regenerative approach is gaining traction in response to the twin pressures of climate change and ecological degradation.</p><p>In viticulture, there is no universally agreed definition of what counts as “regenerative" – but it generally involves farming in ways that improve soil health, promote biodiversity, reduce reliance on synthetic inputs, and potentially sequester carbon.</p><p>Yet despite growing interest, most claims about regenerative wine farming remain anecdotal. ReGenWine wants to change that.</p><p>“This is a proof-of-concept study," Prof Melané Vivier, Director of SU's <a href="https://sagwri.sun.ac.za/">South African Grape and Wine Research Institute</a> (SAGWRI) and head of ReGenWine said at the launch of the project recently. “We're looking at how to work with nature rather than against it – and whether that can deliver measurable benefits for wine farmers."</p><p><strong>Restoring life to the land</strong></p><p><img src="/english/PublishingImages/2025/Wilhelm%20Joubert.%20PIC%20Henk%20Oets.png" class="ms-rtePosition-1" alt="" style="margin:5px;width:330px;height:231px;" />The main trial site is Hartenberg – a wine estate with deep roots and progressive ambitions. Established in 1692, it is one of South Africa's oldest wine farms, yet it has become a frontrunner in sustainability with innovative practices.</p><p>Hartenberg has gradually shifted its approach to farming over the past two decades, introducing multi-species cover crops, composting and biological pest control. But this transition really gained momentum in 2017 with the adoption of holistic grazing – integrating livestock into their vineyards.</p><p>Earlier this year, Hartenberg became the first wine estate in South Africa, and only the second globally, to be verified under the <a href="https://savory.global/eov/">Ecological Outcome Verification (EOV) framework</a> – an evidence-based standard for monitoring and improving soil and plant health.</p><p>“When we brought animals in, everything changed," said Wilhelm Joubert, Hartenberg's viticulturist. “We've seen the land come alive again – from the return of earthworms and dung beetles to improved soil structure and biodiversity."</p><p>However, he highlighted challenges as well. “It's romantic to have animals on the farm – but it's a 24/7 job. They need to be managed. You need to control grazing to get the most out of your cover crops."</p><p><strong>Backing research for impact</strong></p><p>South Africa Wine is financing the project and backing its potential impact. “For us, it's about relevance," Gerard Martin, the industry body's Executive for Research Development and Innovation, said.</p><p>“Everywhere I go these days, people are talking about sustainability. They're asking about regenerative farming and what it might mean for their winemaking and their business. This study will generate valuable insights to help the industry make more informed decisions."</p><p><strong>How the model works</strong></p><p>ReGenWine studies regenerative viticulture in a real-world setting, on a working farm:</p><ul style="list-style-type:disc;"><li>A mix of oats and various grass species is sown between vineyard rows as cover crops to protect the soil, retain moisture, suppress weeds and support biodiversity.</li><li>After the grape harvest – and before new vine growth begins – cattle are brought in to graze the cover crops. This timing ensures they do not eat the vine leaves or grapes.</li><li>As the animals move through the vineyard, their manure and urine replenish the soil – reducing the need for synthetic fertilisers.</li><li>This integrated approach supports soil health and vine performance, while also creating a circular benefit: the cattle gain weight and can be sold or used for meat products in the farm's restaurant, providing an additional income stream.</li></ul><p>While Hartenberg is well-known for its striking Ankole cattle – a large-horned breed that has become part of its visual identity – the ReGenWine study uses Dexter cattle, a smaller and more manageable breed well suited to the tight layout and conditions of vineyards.</p><p><strong>Five teams, one mission</strong></p><p><img src="/english/PublishingImages/2025/ReGenWine.%20PIC%20Henk%20Oets.png" class="ms-rtePosition-1" alt="" style="margin:5px;width:545px;height:382px;" />The project builds on a two-year pre-trial begun at Hartenberg in 2022. Encouraging results prompted researchers to expand their study.</p><p>“It wasn't difficult to bring the teams together," Vivier said. “Many of us were already working on aspects of this, but no single person or discipline can cover all of it. That is why this is such a collaborative project – and that is a strength."</p><p>The project is structured around five interdependent and multidisciplinary work packages (WPs), each led by a senior academic and supported by postgraduate students from different faculties.</p><p><em>WP1: Soil system</em> – Led by Prof Cathy Clarke and co-led by Dr Lawrence Munjonji (<a href="/english/faculty/agri/soil-science">Department of Soil Science</a>), this team assesses carbon levels, microbial activity, soil structure, and water retention.</p><p>“On the physical side, we're mainly looking at soil compaction," Munjonji said. “Some believe that introducing cattle to vineyards causes compaction, others disagree. We want to test this and provide evidence either way."</p><p><em>WP2: Grapevine to wine system</em> – Headed by <a href="/english/faculty/agri/viticulture-oenology">Viticulture and Oenology</a> lecturer Dr Erna Blancquaert, with Vivier as co-leader, this group is tracking vine growth, berry ripening (in viticulture, a “berry" refers to an individual grape), and juice composition using field measurements and remote sensing. The goal is to determine whether regenerative practices influence vine balance and wine quality.</p><p>“I completed my BSc last year," Dylan Endeacott said “Now, for my MSc the next two years, I will be analysing how livestock integration affects both vine and wine." He already made wine from Hartenberg grapes – during the pre-trial last year – “and it went well," he told the launch audience with a smile.</p><p>SU is the only university in South Africa that offers undergraduate and postgraduate courses in Viticulture and Oenology.</p><p><em>WP3: Cover crop and animal system</em> – Under the leadership of Dr Brink van Zyl and Prof Pieter Swanepoel (chairs of <a href="/english/faculty/agri/animal-science">Animal Sciences</a> and <a href="https://agronomy.sun.ac.za/">Agronomy</a> respectively), this unit explores livestock integration. “Vineyards are not usually set up to accommodate livestock," Van Zyl said. “During the pre-trial, Wilhelm had quite the time keeping the animals in their blocks – they're herding animals, they want to be with their friends!"</p><p>To improve compatibility with vineyard conditions, the large-horned Ankole cattle used previously have been supplemented by the smaller, more manageable Dexter breed. They will be deployed in pairs, and researchers will regularly measure the test herd of 24 cattle for dry matter intake, weight gain and nutrient return to the soil.</p><p><em>WP4: Economic and environmental circularity</em> – With Prof Eric Mungatana (<a href="https://agricultural-economics.sun.ac.za/">Agricultural Economics</a>) at the helm and Prof Annie Chimphango (<a href="https://chemeng.sun.ac.za/">Chemical Engineering</a>) as co-lead, this work package models input-output flows across four vineyard configurations, calculates return on investment, and evaluates life cycle impacts.</p><p>“As engineers, we look at systems, which explains why we're involved," Dr Erik Wolfaardt, a postdoctoral researcher supporting the modelling, said. “This project is a complex process with many moving parts."</p><p><em>WP5: Project and knowledge coordination</em> – Led by Julia Harper in the office of the Dean of <a href="https://agric.sun.ac.za/">AgriSciences</a>, this package ensures that data sets are curated, shared and ethically managed, and that results are disseminated through regular team meetings and industry engagement.</p><p><strong>Laying the groundwork</strong></p><p>For all its practical promise, ReGenWine is fundamentally about scientific evidence.</p><p>“We do not expect to answer everything in one study," Vivier said. “But we do hope to provide a solid base that others can build on."</p><p>“It's also about positioning," added Martin. “We're showing that South Africa isn't just following global trends – we can deliver world-class outcomes when we work together."</p><p>* * * * <br></p><p>Desmond Thompson is a freelance journalist.</p><p>CAPTIONS:</p><p>TOP PICTURE: Cattle grazing on cover crops in the vineyards at Hartenberg Wine Estate.

Data from river basins that are relatively undisturbed by human impacts are important for efforts to detect climate-driven hydrological trends and make informed decisions on climate adaptation strategies. </p><p>The ROBIN dataset is now publicly available <a href="https://catalogue.ceh.ac.uk/documents/3b077711-f183-42f1-bac6-c892922c81f4">here</a>. Additionally, a new open access <a href="https://www.nature.com/articles/s41597-025-04907-y">Data Descriptor paper</a> explains how the network and dataset were developed.</p><p>Dr Andrew Watson, a senior researcher in Stellenbosch University's <a href="https://climate.sun.ac.za/">School for Climate Studies</a>, says they worked with SAEON to contribute streamflow data to ROBIN: “SAEON has a number of critically important observation points away from human-made distribution infrastructure such as reservoir releases, wastewater treatment plants, and irrigation. This data can be used to analyse climate change impacts and trends," he explains.</p><p>One such observation point is at Jonkershoek outside Stellenbosch – the <a href="https://fynbos.saeon.ac.za/?p=3183">Jonkershoek multiple catchment experiment</a> has been running since the 1930s and is the oldest in Africa and one of the longest running in the world. One can even view real time data from SAEON's high altitude weather station <a href="https://lognet.saeon.ac.za/Dwarsberg/index.html">here</a>. The streamflow data, shared with ROBIN, is archived and stored on the <a href="https://eur03.safelinks.protection.outlook.com/?url=https://catalogue.saeon.ac.za/&data=05%7c02%7c%7c9fbe1e92e5ce46991c7708dd8c8e4795%7ca6fa3b030a3c42588433a120dffcd348%7c0%7c0%7c638821264964770792%7cUnknown%7cTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7c0%7c%7c%7c&sdata=LQ5xr2b7X0t70KVLA2K0OZT5ccM9p1sgrfUcIt6128g%3D&reserved=0">SAEON Data Portal</a>. </p><p>The ROBIN initiative, established in March 2022 and led by the United Kingdom Centre for Ecology & Hydrology (UKCEH), has created a long-term collaboration of international experts, now including more than 60 partner organisations from 30 countries across five continents. </p><p>In a media release issued by UKCEH, Prof. Peter Thorne from Maynooth University in Ireland said the latest <a href="https://www.ipcc.ch/report/ar6/wg1/">Assessment Report</a> of the Intergovernmental Panel on Climate Change (IPCC) indicated “low confidence" in patterns of observed change in global streamflow trends: “Much of this lack of confidence relates to the relative absence of rivers which are unperturbed by other human factors. With ROBIN providing a set of long-term, sustained measurements which are, to the extent practical, free of human perturbations, future assessments of global streamflow can potentially discern with higher confidence any signal that may exist."</p><p>By bringing this information together and making it available for wider use, ROBIN represents a significant advance in global-scale, accessible streamflow data. The ROBIN dataset also has full metadata for 3,060 gauging stations, including those providing daily flow data. Most records span at least 40 years, though some date to the late 19th century.</p><p>According to the media release, global-scale analysis of trends in river flows using undisturbed catchments is important for many reasons. Future IPCC assessments and other policy-relevant reports need such data to better understand how climate change affects river flows but there are other potential uses beyond looking at climate impacts. Hydrologists and water managers need to know natural variations in river flow in order to detect the impacts of human disturbances (dams, abstractions) in more modified catchments. In turn, ecologists can help understand these impacts on river ecosystems. </p><p><strong>Notes on the dataset</strong></p><p>ROBIN is an 'open science' initiative where all data and code are shared, to enable partners (and the wider community) to replicate analysis. A code library for ROBIN is <a href="https://github.com/NERC-CEH/ROBIN_pipeline">available here</a>, highlighting its potential for research and educational purposes across the environmental sciences. </p><p>Data were quality controlled by the central ROBIN team before being added to the dataset, and two levels of data quality are applied to guide users towards appropriate the data usage. <br></p><p><br></p> |
| Cutting off parasite’s energy supply could help fight malaria | https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=11259 | | Cutting off parasite’s energy supply could help fight malaria | Corporate Communication and Marketing/Korporatiewe Kommunikasie en Bemarking [Alec Basson] | <p>In 2023, malaria caused 597 000 deaths worldwide, according to the World Health Organization, with most occurring in Africa, where the deadliest malaria parasite, <em>Plasmodium falciparum</em>, is most prevalent. Once inside the body of an infected person, the parasite relies on a process called glycolysis—breaking down glucose (a sugar)—to produce energy and stay alive.<br></p><p>A new study at Stellenbosch University (SU) found that blocking the enzymes involved in this process could cut off the parasite's primary energy source and kill it. Some of these enzymes could also be good targets for new malaria drugs.<br></p><p>“Plasmodium falciparum relies heavily on free energy produced during glycolysis for its survival, growth and replication. It consumes vast amounts of glucose from the host's red blood cells to survive. If we can block the breaking down of sugar, it will be harder for the parasite to mutate or evade suppression without suffering severe consequences," says Dr Tagwin Frantz who recently obtained her PhD in biochemistry at SU.<img src="/english/PublishingImages/Lists/dualnews/My%20Items%20View/TFrantz.png" alt="TFrantz.png" class="ms-rtePosition-2" style="margin:5px;width:348px;height:469px;" /><br></p><p>As part of her study, Frantz tested three chemicals to determine how they affect the parasite's glucose metabolism, growth and use of available energy utilising experimental and modelling approaches to identify potential drug targets. Each chemical blocked a different enzyme (hexokinase, phosphofructokinase and glyceraldehyde-3-phosphate dehydrogenase) involved in breaking down sugar, securing a continuous energy supply, maintaining the parasite's redox balance (how it manages chemical reactions to produce energy and protect itself from harmful molecules) and helping it to survive. <br></p><p>Frantz says that two of these chemicals are known to inhibit the parasite's ability to extract nutrients from its host, converts them into energy, and adapts its biochemical processes for survival and reproduction. The chemicals—one being Spinosad, an insecticide derived from the bacteria <em>Saccharopolyspora spinosa</em> and used against pests like mosquitoes—have shown the ability to fight the parasite though the exact mechanism of action is unknown. These chemicals were tested on the isolated parasite, red blood cells (both infected and uninfected), and a type of bacteria used in biotechnology and medicine.</p><p>“Our results show that by inhibiting these enzymes, glucose cannot enter glycolysis, cutting off the parasite's primary energy source. Additionally, glycolysis could also be halted entirely, leading to a rapid energy crisis in the parasite, starving the parasite of energy, likely disrupting its redox balance and leading to its death.<br></p><p>“It is crucial to prevent glycolysis during the blood stage, i.e. the phase where the parasite, after entering the bloodstream from the liver, replicates within red blood cells, causing the clinical symptoms of malaria. Preventing glycolysis to kill the parasite is especially effective in infected individuals, where a fever that causes the body to work harder and use up more energy also makes the parasite more vulnerable. However, it can be challenging since both human cells and parasites undergo glycolysis.<br></p><p>“Beyond the blood stage, inhibiting glycolysis could also indirectly reduce the transmission of the parasite to the mosquito."</p><p>Targeting how the organism extracts nutrients from its host and converts them into energy metabolism (rather than traditional drug targets) offers a new way to kill resistant parasites, according to Frantz.<br></p><p>She points out that Spinosad directly inhibits the parasite's metabolism without damaging red blood cells.<br></p><p>“Since two of the three enzymes (hexokinase and phosphofructokinase) are essential and structurally distinct from human enzymes, selective inhibitors can be designed to minimise side effects. Combining either one of these enzyme inhibitors with current standard treatment for <em>Plasmodium falciparum</em> malaria (artemisinin-based therapies) could further reduce risks, making them valuable targets for new malaria drugs."</p><p>Frantz mentions that testing the effectiveness of chemicals against the parasite – and finding a dose that kills the parasite without harming red blood cells or other host tissues – was challenging. Another hurdle was ensuring that the parasite wouldn't quickly develop resistance to these compounds. To tackle these issues, she tested the long-term effects of the inhibitors over multiple parasite life cycles.<br></p><p>Frantz says that although her research is still in its early stages, it could be a building block for developing new malaria drugs. <br></p><p>“This study advances malaria research by pinpointing critical points where drugs can effectively target the parasite and predicting the most vulnerable parts of its energy-producing processes. These insights could help to develop next-generation malaria medicine that combat resistance, target multiple parasite lifecycles, and are safer for humans – supporting global efforts to eradicate the disease.<br></p><p>“With rising drug resistance, finding new drug targets is crucial to prevent treatment failure and protect millions at risk. Continuous innovation is key to eliminating malaria and staying ahead of the parasite's adaptation. Additionally, contributing to the broader understanding of how metabolic interventions (adjusting how the body uses energy and nutrients) can be leveraged to combat parasitic diseases.<br></p><p>“Future success will depend on the design of precision drugs, the use of combination therapies, and targeted delivery to kill the parasite while sparing human cells," adds Frantz. <br></p><p><br></p> |

| Tax systems in Africa must be revamped to boost economic growth | https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=11220 | | Tax systems in Africa must be revamped to boost economic growth | Corporate Communication and Marketing/Korporatiewe Kommunikasie en Bemarking [Alec Basson] | <p>A new study at Stellenbosch University (SU) found that tax administration in many African countries is inefficient, hindering revenue collection. This points to potential gaps that could be addressed through institutional reforms. <br></p><p>“Widespread inefficiencies in tax systems undermine the mobilisation of government resources, limiting their capacity to deliver public services and make essential investments. These inefficiencies create systemic gaps that foster corruption and manipulation, often exacerbating income inequality," says Dr Onesmo Mackenzie, who is a postdoctoral research fellow in the Department of Economics at SU. He recently obtained his doctorate in Economics at the University. <br></p><p>As part of his study, Mackenzie used different techniques and case studies to investigate the efficiency of tax administration in 32 African countries, including South Africa, from 2000–2021. He sourced data from multiple organisations, including the African Tax Administration Forum and the World Bank. <br></p><p>Mackenzie says many countries in Africa lack the capacity and technological infrastructure to maintain accurate taxpayer databases. <br></p><p>“Tax authorities are often understaffed and lack proper data management systems to effectively track taxpayers, collect data and store records. The absence of proper records for some taxpayers further complicates this process.<br></p><p>“A lack of institutional coordination limits the ability of tax administrations to cross-check taxpayer data with third-party organisations.<br></p><p>“Perceived inefficiencies erode taxpayers' trust in tax administration, reducing compliance and further weakening the system. Ultimately, such inefficiencies lead to significant revenue losses, diminishing fiscal capacity, hindering economic growth and development and increasing reliance on external support."<br></p><p>According to Mackenzie, efficient tax administration seeks to maximise revenue within the limits of available resources and the tax base. It also prevents unequal tax burdens on particular groups, promoting fairness and enhancing taxpayers' trust in government institutions.<br></p><p>“By enhancing efficiency, tax authorities in Africa can curb revenue leakages, and tackle corruption, tax evasion and avoidance to ensure stable revenue. This will, in turn, empower African countries to fund their development priorities, reduce dependence on external aid, and promote equity and trust." <br></p><p>He adds that in African countries with large informal sectors, efficient tax systems can play a key role in engaging with the informal economy, thereby expanding the tax base.<br></p><p>Mackenzie expresses surprise at seeing that efficiency levels vary depending on the type of indicator used. “Notably, African countries excel in tax registrations, yet they struggle to translate them into revenue because taxpayers remain inactive in filing and paying taxes." <br></p><p>According to Mackenzie, the continent's low tax-to-GDP ratio—the revenue a country generates from taxes compared to its economic output—indicates the potential for revenue growth. A higher ratio means more tax revenue, while a lower one could suggest challenges with tax collection or a smaller tax base. According to Mackenzie, improving tax administration could help tap into this potential.<br></p><p>He also emphasises the importance of elites paying their taxes. “Their contributions are significant and when they comply, governments can collect more revenue. Elite compliance shapes broader taxpayer behaviour, as individuals often judge fairness based on the taxes paid by high-income earners. Non-compliance by the elite can increase non-compliance among other taxpayers. <br></p><p>“Tax authorities are more successful in ensuring compliance and meeting revenue targets when elites back tax policies and reforms, rather than resisting them. To enhance revenue mobilisation, African countries might have to prioritise strategies to improve elite compliance and effectively address their resistance to tax reforms." <br></p><p>Mackenzie says tax administrations should use multiple indicators to assess their performance and ensure that registered taxpayers are actively contributing to revenue generation. <br></p><p>“They should also enhance taxpayer education and consider replacing the term 'tax administration authority' with 'tax administration service' to improve the relationship between tax officials and taxpayers, shifting the focus from coercion to voluntary compliance. <br></p><p>“They must become more responsive to the needs of taxpayers by making it easier for them to file returns, make payments, access tax information and services for personalised support, and know about tax obligations, rights and benefits." <br></p><p>Mackenzie urges African governments to support tax authorities by ensuring effective use of revenue for public services and investments. <br></p><p><br></p> |
| Together, we can do bolder things, says new Stellenbosch University Rector | https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=11212 | | Together, we can do bolder things, says new Stellenbosch University Rector | Corporate Communication and Marketing / Korporatiewe Kommunikasie en Bemarking | <p><em>“This is a really good university that is already globally recognised for its research excellence. But there are bolder things we can do and greater ambitions that we can have – together. This can culminate in us having even greater impact on society."</em></p><p>Prof Deresh Ramjugernath (52), the 13<sup>th</sup> Rector and Vice-Chancellor of Stellenbosch University (SU), officially stepped into his new role this morning (1 April 2025). </p><p>He takes over from Prof Wim de Villiers who completed two terms at the helm. </p><p>“Stellenbosch has a proud history of excellence in learning and teaching. Under Prof De Villiers, we have also become a strong research-intensive university. But we cannot be complacent. We must now move from good to great – continually striving to improve our teaching, research, innovation and social impact."</p><p>A seasoned and highly experienced higher education leader with extensive senior executive experience in the sector in South Africa, Ramjugernath served as the Deputy Vice-Chancellor: Learning and Teaching at SU since January 2021. </p><p><strong>Academic success</strong></p><p>A more than capable cricketer in his younger days (an allrounder shining with both bat and ball) he knows only too well that in captaining one of Africa's leading research-intensive universities, there will be many difficult balls to face. </p><p>In higher education you don't advance as an institution by only playing a defensive game, states Ramjugernath. “You need to play a bold, big game. For me, Stellenbosch being the first African university to feature among the top 100 universities in the world, will be that bold step for us. </p><p>“This ambitious goal of global excellence should not be the sole aim though. Stellenbosch 'advancing knowledge in service of society' – to quote in part our vision – should be what we all strive for. This is in the light of much noise out there of what universities can and should be. To reach that goal our focus should be first and foremost the academic project, and to ensure that we have the best academic offerings."</p><p>It is for this reason that Ramjugernath views academic excellence to be front and centre as one of his three focus areas for the next few years – with the other two being people, culture, and processes; and, partnerships and sustainability.</p><p>“One of our biggest challenges will undoubtedly be sustainability. This includes financial, social and environmental sustainability. Issues around funding – particularly NSFAS and student debt – are destabilising. Coupled with that is the misconception that a university degree is the only path to success, which burdens universities further. At the same time, universities must do more to equip graduates with not just technical knowledge but also skills, competencies and attributes for employability. That's why we will further pursue academic renewal at SU.</p><p>“And a big part of this will be the notion of futureproofing through technology. Embracing artificial intelligence, digital transformation and hybrid learning isn't optional – it's essential. It is the single biggest opportunity to improve higher education." </p><p>Overseeing the portfolio of student affairs over the last four years has given him added insight into the lives of students. “We need to become even more student-centred because student success and employability of our graduates are the highest priorities from a learning and teaching perspective. </p><p>“We want to create an academic environment where every student, regardless of their socio-economic background, has the resources, mentorship and opportunities needed to thrive. I believe universities should not only educate, but also empower, ensuring that each student can contribute to South Africa's development, economic growth and overall well-being.</p><p>“That is why our commitment extends beyond academic achievement. As we work to secure greater donor funding, establish new partnerships and strengthen existing ones, we are dedicated to building a future where every student has access to holistic support – academic, financial, psychological and professional. This comprehensive approach to student success reflects our belief that education is not simply a pathway to employment but a catalyst for positive social change.</p><p><strong>People, culture and processes</strong></p><p>“The world is changing and with it the world of work. And that is why I also want to focus on fostering a humanising and enabling culture at the University. I want to prioritise people, culture, and systems that will allow everyone at SU to thrive." </p><p>Bringing out the best in people is a question of working together in an inter-, multi- and transdisciplinary manner, reckons Ramjugernath. “Some of the greatest breakthroughs we see now is the result of interdisciplinary research – by fostering a sense of teamwork. That is how we tackle the most 'wicked problems' in the world. </p><p>“We can only be great if we work together and, importantly, if we all move forward together. I believe in a fresh, service-oriented approach to leadership. I lead by example – if I expect academic excellence, I must model it myself. Leadership, to me, is about service, not status. It's about empowering others – giving people agency and helping them realise their potential, just as others did for me."<br><br></p><div class="ms-rtestate-read ms-rte-embedcode ms-rte-embedil ms-rtestate-notify"><iframe width="560" height="315" src="https://www.youtube.com/embed/59grvoWKCjY?si=S0BucRZcNH4E2L6-" title="YouTube video player" frameborder="0"></iframe> </div><p><br></p><p><strong>Partnerships and sustainability</strong></p><p>“Universities cannot thrive in isolation. Strategic partnerships are the keys to sustainability and to opening doors to opportunity. We need to further grow our various streams of income to the benefit of all partners. </p><p>“Amongst others, I am broadening our internationalisation agenda. It's however not just about collaborating with other universities but also with government, civil society and industry – both locally and globally. To support this, we will be establishing a Partnerships Office to coordinate efforts while empowering champions across the University.</p><p>“In all of this, we should not forget our unique setting, says Ramjugernath. “Stellenbosch is known as the innovation capital of South Africa – an African equivalent of Silicon Valley. In our work, our teaching, our research, and our social impact, we should adopt an entrepreneurial mindset. To a large degree, this is what inclusive transformation is about – it means belonging, representation, and growth. It is about building a truly diverse, inclusive, multicultural, and multilingual institution where we should never settle for complacency but continue changing, exploring, and discovering. Transformation is about fostering a culture that brings out the best in everyone."</p><p><strong>Shoulder to the wheel</strong></p><p>Universities are only great when they have the support of all its stakeholders, says Ramjugernath. “I firmly believe we have what it takes, and I am excited to now put shoulder to the wheel with the support of my management team and our incredible staff, our Council, our alumni, our donors and the many other stakeholders, partners and friends of our beloved University. Let's shape tomorrow together – one conversation, one breakthrough, one act of courage at a time."</p><p style="text-align:center;">----------</p><p>The Chair of Council, Dr Nicky Newton-King, commented that Council is excited about Ramjugernath's bold vision for the University with academic excellence, people and partnerships at its centre. “Prof Ramjugernath is stepping into this role at a challenging moment for all higher education institutions. At the same time, there are great opportunities to position Stellenbosch University, its academics and students for top tier academic performance and to build deep and sustainable partnerships in South Africa, on the African continent and abroad with other higher education institutions and the private sector. As an excellent academic and seasoned administrator, Council looks forward to Prof Ramjugernath's stewardship of our special institution."</p><ul style="list-style-type:disc;"><li>Ramjugernath resides in Stellenbosch with his wife, Prof Prathieka Naidoo, an accomplished academic in her own right, and their three daughters. Besides being a dog lover and an avid sports fan who plays tennis, paddle and golf, Prof Ramjugernath loves the outdoors. </li></ul><p><strong>MORE ABOUT PROF DERESH RAMJUGERNATH</strong></p><p>Before making Stellenbosch his home, Prof Deresh Ramjugernath was Deputy Vice-Chancellor: Research and Pro Vice-Chancellor: Innovation, Commercialisation and Entrepreneurship at the University of KwaZulu-Natal. </p><p>He boasts extensive board and governance experience having served on several company and organisation boards.</p><p>A pre-eminent scientist in the field of chemical engineering and specifically in chemical thermodynamics and separation technology (becoming the youngest full professor in his field in Africa at age 31), Ramjugernath served as the DST/NRF South African Research Chair (SARChI) for Fluorine Process Engineering and Separation Technology until 2018.</p><p>He has successfully graduated over 130 master's and PhD students and supervised over 20 postdoctoral fellows.

| African universities should reaffirm their positions as full partners | https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=11202 | | African universities should reaffirm their positions as full partners | Petro Mostert | <p></p><p>The African collaboration workshop, the precursor for SU International's annual Stellenbosch International Academic Network (SIAN) meeting, this year placed the concept of fair partnerships in higher education under the spotlight, highlighting the need for institutions on the continent to stand their ground as fully-fledged partners in collaborations with international partners.</p><p>As part of the workshop, three panellists, Lea Mehari Redae, Director of External Relations, Partnerships and Communications at Addis Ababa University, Gerald Ochwo, Manager of international Students Services in the Office of the Vice-Chancellor at Uganda's Makerere University, and Professor Bernard Ikua, DVC at Jomo Kenyata University of Science and Technology (JKUAT), shared their views on fair partnerships for an African perspective.</p><p>Dr Nico Elema, Director of the Centre for Collaboration in Africa (CCA) at the SU International, highlighted the need to amplify the voice of African institutions in these conversations: “When we talk about fair partnerships, the importance of our unique contexts is often ignored, and it is important for us to have panellists form the African continent to express their views. We were delighted to have our colleagues share their views in the panel discussion, which were then followed up by table discussions where everyone, including the partners from beyond Africa, could engage and understand each other views and contexts better".</p><p>Redae highlighted the need for African universities to reaffirm their positions as fully-fledge partners. “For far too long, African universities, including ours, were engaged in partnerships where we are considered the junior partner. We're led by external conditions, such as conditions determined by donors, and where research priorities were not our own but donor-driven. They expect us to fit into their framework."</p><p>Redae said while collaboration is essential, it is also crucial for a partnership to be fair and that it is based on co-creation, mutual respect, and shared leadership. “At Addis Ababa University, we are now focusing on working with other African universities, as well as those from the global South, because we have come to understand that transformative change for the continent has to begin within the continent. So we should try to build our relations, research networks, and share our expertise within the continent."</p><p>Redae also highlighted the importance of financial independence and developing local funding opportunities. “Many African universities rely on foreign funding, which often comes with its restrictions. It is high time that we develop our funding opportunities that we can control and compete for, enabling us to set our research priorities. We have unique problems, pressing needs, and challenges. This would also help us enhance student mobility within the continent itself."</p><p>Redae emphasised the need for staff mobility to experience new learning opportunities and develop our institutions from the inside. She also discussed the issue of trust within African institutions and the need for harmonised degree recognition.</p><p>Professor Ikua from Jomo Kenyatta University of Agriculture and Technology stressed the significance of a shared vision and mutual respect in partnerships. This relatively young institution, which became a fully-fledged University in 1994, focuses on agriculture and technology development. He mentioned that the university already collaborates with many African universities, some in Europe and many in Japan and shared many examples of successful partnerships and projects, amongst others, the development of resources in the Rift Valley, a geothermal development project in Kenya and a partnership focusing on entrepreneurship and sustainable energy in Uganda. “These are successful projects and partnerships because we share a common vision, and we are working towards solving actual challenges we are experiencing in our countries."</p><p>Professor Ikua highlighted the need for flexibility, resource sharing, and clear roles and obligations in partnerships. “We have signed agreements in partnerships, but some changes occur along the way. It is essential that also we can accommodate these changes."</p><p>Ochu from Makerere University highlighted the role of practical skills and innovation hubs in enhancing student mobility and partnership sustainability. He discussed the comprehensive nature of his university and its focus on solving local problems with partnerships.</p><p>Ochu shared an example of an electric bus project amidst the country's greatest problems: traffic. “Those of you that have been to Kampala city will know it is a very chaotic city with many “matatus" (minibus taxis) and “boda-boda's" (motorcycles). About a decade ago, his university came up with a solar automobile bus: an idea they've shared with their government first, as the “mess in the city, made the government look terrible."</p><p>The Ugandan government invested in 70 percent of the project which gave rise to the Kiira Vehicle Plant (KVP) in Jinga; “the largest manufacturing facilities in East Africa and positioned Uganda at the forefront of sustainable vehicle production in Africa," writes the <a href="https://observer.ug/news/kiira-vehicle-plant-opens-aiming-for-2-500-annual-vehicle-output/">Observer</a>. “The facility's impressive production capacity—starting at 2,500 vehicles per year and scalable to 5,000—aligns with Uganda's ambitions to establish itself as a regional leader in vehicle manufacturing."</p><p>Ochu also highlighted the role of practical skills and innovation hubs in enhancing student mobility and partnership sustainability.</p><p>The panellists also touched on the challenges of trust, accreditation, and the need for intellectual property commercialisation to ensure sustainability.</p><p>The discussion that followed the panel discussion highlighted the need for sustainable funding models and the role of individual partnerships. The Africa Charter was mentioned as a significant initiative to shift research collaborations to African-led agendas. Challenges such as power imbalances, brain drain, and the need for local impact and regional relevance were also discussed. The session emphasised the importance of mutual interest, equitable project distribution, and co-creation in fostering fair partnerships.</p><p>Following the panel discussions, Dr Elema highlighted the significance of the panel members also starting off with, without a prompt, highlighting their collaborations on the African continent before elaborating on their partnership beyond the continent. “There are so many collaborations currently undertaken between African universities and we should not just look at internationalisation to the global north. Yes, we should continue to nurture bi-lateral partnership globally, with even more opportunities arising for tri-lateral and multi-lateral partnerships, often based on specific themes".</p><p>The workshop underscored the need for African institutions to articulate their offerings clearly and to complement each other's weaknesses within Africa and with global partners. The youthful population in Africa was noted as a significant asset, emphasising the need to prepare young people for future leadership roles.</p><p> </p><p><br></p> |
