Kay-Leigh van Rooyen, Research Assistant at the University of the Free State (UFS), was one of sixteen individuals selected to participate in the 2024 Abe Bailey Travel Bursary.

As one of only sixteen recipients of the prestigious 2024 Abe Bailey Travel Bursary, Kay-Leigh van Rooyen, Research Assistant at the University of the Free State (UFS), recently returned from a life-changing journey across the United Kingdom. Representing the UFS on this esteemed programme, van Rooyen joined a cohort of emerging South African leaders in a transformative cultural and academic exchange. 

Reflecting on the experience, she described it as “nothing short of amazing.” 

“The experience was so much more than just visiting new places,” she said. “It was about engaging in meaningful conversations, forming lasting relationships, and gaining fresh perspectives on global issues.”

The Abe Bailey Travel Bursary aims to empower young South Africans through leadership development, cross-cultural exchange, and exposure to international dialogue. According to van Rooyen, this initiative was a powerful platform for personal growth, enabling her to see the world – and South Africa - through new lens.

“I learned the power of perspective - how others view our country, and how to understand global challenges from diverse vantage points,” she said. “I also realised that leadership is not about titles, but about influence and empathy.” 

 

A journey through the UK 

The bursary cohort convened in Cape Town on 23 November 2023 before departing for the UK, where they travelled from London to Edinburgh and back. The programme officially concluded on 18 December 2024/3. 

During the tour, the group visited iconic institutions such as the Royal Observatory in Greenwich, the British Library, the Francis Crick Institute, and the Houses of Parliament. For van Rooyen, the highlight was the opportunity to engage with thought leaders and changemakers. 

“One of the most memorable moments was having lunch in a chamber of the House of Lords at the Palace of Westminster with Lord Karan Bilimoria, the founder and chairman of Cobra Beer. The conversation was insightful and inspiring,” she said.  

 

A global stage for the UFS

Van Rooyen emphasised the professional impact of the experience, noting how it shaped her perspective on the role of academia in society. 

“This experience has changed the way I approach my work. I’ve developed a deeper appreciation for the importance of bridging the gap between academia and industry - especially how we can make research more practical and impactful,” she explained. 

She also highlighted the broader benefit for the UFS community. 

“Global engagements like these position the UFS as part of the international conversation. Our students and staff have valuable insights to share,  and we can learn so much from other institutions.” 

Prof Vasu Reddy, Deputy Vice-Chancellor: Research and Internationalisation at the UFS and Chair of the university’s Abe Bailey Travel Bursary selection committee, echoed these sentiments. 

“The Travel Bursary so elegantly aligns with the vision and heart of the UFS - namely, to expose our students to a wider world and its global connections,” he said. 

 

Inspiring the next generation of UFS leaders 

Encouraging fellow UFS staff and students to apply for the bursary, van Rooyen emphasised the personal and professional rewards. 

“It challenges you to think critically, engage meaningfully, and build relationships with people you wouldn’t ordinarily meet,” she said. 

Prof Reddy praised van Rooyen for her achievements and representation of the UFS on a global stage.  

“Her experiences and insights demonstrate that she is an exceptional ambassador – not only as an Abe Bailey alumnus, but also as a symbol of the excellence the UFS strives for. We are extremely proud of Kay-Leigh and wish her well as we look forward to the great things that lie ahead for her.”

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
