Prof Philippe Burger, Dean of the Faculty of Economic and Management Sciences at the University of the Free State, appointed to the DHET Expert Panel on University Fees to help shape the future of tuition affordability and sustainability in South Africa.

Prof Philippe Burger, Dean: Faculty of Economic and Management Sciences at the University of the Free State (UFS), has been appointed as a member of a team that will represent Universities South Africa (USAf) in a DHET Expert Panel on University Fees. The panel, which comprises representatives from USAf, the DHET, and NSFAS, focuses on the affordability of tuition fees and the future sustainability of the sector, looking at potential solutions for tuition fees beyond the 2025 academic year. 

With more than 30 years of experience in higher education, mostly in management positions, Prof Burger understands the sector well. Combined with his expertise in macroeconomics, fiscal policy, and public sector economics and finance, he is uniquely positioned to make a significant contribution to this task team.

 

Universities matter

Despite the high national unemployment rate (32%), Prof Burger points out that unemployment is largely a problem of the unskilled. “The unemployment rate of people with university degrees is about 12%, much lower than the national average,” he notes. “South Africa has a large shortage of skilled labour, which it needs to grow the economy and improve lives.” He trusts that universities can fill this void, in addition to providing the thought leaders needed to take the country forward.

Although universities in South Africa are experiencing financial pressures, they continue to lift thousands of people to better lives each year. Universities make a profoundly positive contribution to the country and its population, and Prof Burger believes that once the public is fully aware of this, it will support broader discussions in favour of higher education.

 

The challenge

Universities face several cost pressures that are causing an increase in cost at a higher rate than consumer inflation, Prof Burger explains. “For instance, we buy equipment, software, and journal subscriptions that are all priced in US dollars. Affected by the exchange rate, these types of expenses have increased by much more than the price of consumer goods in South Africa over the past ten years.” According to Prof Burger, increased operational costs, coupled with constrained university income, necessitate a model that will provide universities with enough income to cover their costs while delivering quality education in the long run. 

 

The solution

“There is an argument for universities to become more efficient, and there is certainly room for universities to look at their cost structures, but there is also a limit to what we can do,” Prof Burger says. “It is important to stress that we cannot talk about the sustainability of universities and not contextualise it within a framework that seeks to deliver quality learning, teaching, and research. In the absence of that quality, we will not be able to address the skills shortages and thought leadership that the country needs. And that is the sustainability we need to talk about – the sustainability of quality education and scholarship,” he concludes.

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.
