Prof Gert van Zyl
The Dean of the Faculty of Health Sciences, Prof Gert van Zyl, was recently appointed as the Chairperson of the South African Committee of Medical Deans (SACOMD).

The Dean of the Faculty of Health Sciences at the University of the Free State (UFS), Prof Gert van Zyl, was appointed as the Chairperson of the South African Committee of Medical Deans (SACOMD).

Prof Van Zyl, who has been a member of the SA Committee of Medical Deans since 2001, says it is a privilege and a highlight to again serve the health sciences academic community in this very dynamic and special time for medical schools.

He is especially looking forward to working with a brilliant team of deans and leaders in SACOMD, to build on the achievements of the past, and to excel in those areas that they have collectively decided to pursue for the future.

Taking on the role of Chairperson of SACOMD once more, leading with an outstanding team and a shared vision, signifies a special moment in his career, particularly as he approaches the conclusion of a fulfilling journey as dean. During his tenure, Prof Van Zyl was dedicated to actively contributing to stakeholders in the health sciences arena, including the academic community, SACOMD, as well as staff and students at the university.

He is of the opinion that this position brings exceptional value to both the faculty and the university. “It aligns with their collective vision of academic excellence across undergraduate and postgraduate teaching and learning as well as research,” he states.

SACOMD’s strategy for 2024

The Committee’s goal is to facilitate the optimisation and transformation of academic activities in Health Sciences faculties in order to meet the healthcare, research, and social imperatives of the country.

During a strategic session held in 2023, SACOMD determined the following objectives that align with their goal. According to Prof Van Zyl, they will strive to embrace collaboration, establish trust-based relationships among its members, seek proactive and consensus-driven decision-making, share information (drawing knowledge and insights from each other) to collectively advance thought leadership, and leverage their position as an influencer for improved health sciences training and strengthened health systems.

He says there are some exciting trends in a number of areas that will play an important role in advancing medical and health sciences. This includes the role of artificial intelligence, simulation, and robotic surgery in the academic health sciences arena.

As a committee, they will also look at the establishment of work-based assessment as a requirement in the postgraduate training environment of medical specialists in South Africa, the role of higher education academia in a National Health Insurance (NHI) system, as well as improving undergraduate and postgraduate teaching and learning. “All these activities are already guided by a set of detailed actions, responsibility areas, and academic outcomes,” he says.

Furthermore, they will provide support for new medical schools in order to serve the country in producing excellent health professionals. In doing so, they plan to create a more sustainable funding environment, improve the world-class status of training in both undergraduate and postgraduate teaching, and influence important clinical training platforms to support the academic health sciences agenda.

Patients is our first priority

Although operating on a strategic level in serving the health sciences community, Prof Van Zyl also shares his thoughts with students who aspire to pursue a career in this field. “Choose a career for the right reasons. Do not forget that your patients are your first priority in everything you do. Make the most of the opportunity if you are in the privileged position to be selected to study and build a career in health sciences,” he says.

He adds that resilience is an important characteristic when deciding to pursue a career in the medical field. According to him, it is also key to be a team player, have sound mental and spiritual health, and to have compassion in everything you do as a health sciences professional.

“Play this role as a team member, with the oath you have taken and with the Declaration of Geneva’s emphasis on the welfare of patients as your compass. Live this out in your daily professional activities. You are part of a group of professionals known for healing and caring for communities. Play the role required.”

“Mother Theresa said, ‘I alone cannot change the world, but I can cast a stone across the waters to create many ripples.’” “Create your own ripples!” Prof Van Zyl urges aspiring medical professionals.

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.
