Dr Luyanda Marhaya, Director of Academic Planning and Quality Assurance at the UFS.

Dr Luyanda Marhaya, Director of Academic Planning and Quality Assurance at the University of the Free State (UFS), has been selected by the Department of Higher Education and Training (DHET) to join the Foundation Provision Reference Group (FPRG). His primary role in this position is to assist the Department in assessing applications for foundation programmes submitted by universities, ensuring compliance with the current Foundation Provision Guidelines. 

As the author of the book Does Extended Programme Provision Work in South Africa?, Dr Marhaya is a recognised expert in the field. 

The Department of Communication and Marketing (DCM) at the UFS recently interviewed Dr Marhaya to understand his responsibilities better:

Can you tell us more about your appointment as a member of the FPRG?

Over and above the supportive role, one of the major issues I will be involved in will be to provide input into the revision and finalisation of the Extended Curriculum Programme Policy Framework for the higher sector in South Africa.

What kind of projects or initiatives do you see being a priority?

One of the significant ongoing projects will be evaluating applications for foundation programmes of the different universities in South Africa, so one will have to allocate time, as many universities currently offer these programmes.

What do you hope to bring to the table as a group member?

Interestingly, I started as an academic about 15 years ago in the foundation programmes. I spent a good five years of my teaching at a university level dealing with students who gained entry through foundation programmes. I completely understand their purpose, intentions, and significance, especially concerning student access and success. 

How will the Foundation Provision Reference Group benefit students and the education system?

Student access is a serious issue in South Africa, especially regarding the preparedness of many university students. So, I believe if we develop guidelines that can assist universities in coordinating these programmes in a well-structured manner, there could be many benefits.

What challenges do you anticipate facing in this role, and how do you plan to address them?

I think the major issue will be time constraints. My role is very demanding, and I am already involved in several other external committees, such as the Council on Higher Education, so I think my time management has to be very good.

How do you plan to work with other group members to achieve the group’s goals?

I believe in lifelong learning. I will certainly contribute, but the value of these interactions comes from learning from others.

Can you discuss any past experiences that have prepared you for this role?

I also wrote a book, titled Does Extended Programme Provision Work in South Africa?, in which I explored all the intricacies around these programmes. As Director: Academic Planning at the UFS, I also oversee the quality and provision of foundation programmes, so you could say I bring some expertise.

What are your long-term goals for the foundation programmes, and your role as a reference group member?

I foresee this as a long-term service that will benefit the country as a whole, so I suppose the Department will keep up so that we can provide capacity development to all universities that offer foundation programmes.

Research helps farmers save with irrigation

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.
