Prof Motlalepula Matsabisa, a specialist in indigenous knowledge systems from the Department of Pharmacology at the University of the Free State (UFS), is part of a delegation with Prof Blade Nzimande, minister of Science, Technology, and Innovation (DSTI), to the Second Ministerial Belt and Road Science and Technology conference (BRT) in China. 

The conference is being held in Chengdu from 11-12 June 2025 and will gather representatives from state-level agencies, scientific academies, and innovation enterprises from countries involved in the Belt and Road Initiative, including members of the Association of Southeast Asian Nations (ASEAN) and the Shanghai Cooperation Organisation. The theme of the conference is “Together for Innovation, Development for All – Jointly Building a Scientific and Technological Innovation Community for the Belt and Road”. 

Prof Matsabisa, Research Director of the African Medicines Innovations and Technologies Development at the UFS, is the only person from a South African university to be invited by Prof Nzimande as part of this ministerial trip. Other members of the delegation include members from the minister’s department, CEOs and board members of agencies that report to the DSTI – namely Technology Innovation Agency (TIA), the National Science and Technology Forum (NSTF), Council for Scientific and Industrial Research (CSIR), National Advisory Council on Innovation, Human Sciences Research Council of South Africa, South African Council for Natural Scientific Professions, National Science and Technology Forum (NSTF), National Advisory Council on Innovation (NACI), South African National Space Agency and the National Research Foundation (NRF). 

As a guest professor at the Beijing University of Chinese Medicine (BUCM) in Beijing, Prof Matsabisa accompanied the delegation on a visit to the university where he has a longstanding relationship. The UFS has the only active university collaboration within the China-South African Science and Technology bilateral agreement.

 

Supporting around aspects of traditional medicine 

According to a statement on the South African government website, Prof Nzimande expressed the department’s intention to strengthen collaboration with the Beijing University and the Aerospace Research Institute of the Chinese Academy of Sciences, in the areas of indigenous knowledge systems and space science, respectively. The minister visited both the BUCM and the Aerospace Information Research Institute of the Chinese Academy of Sciences this week. 

“It is an honour to be part of the minister’s delegation given that I am the only person from a university amongst the agencies. The UFS is indeed very honoured to have been the only one identified to be in this ministerial trip. I am honoured to make connections with the decision-makers such as the chairperson of the board of TIA and the CEO of NSTF and all the other CEOs. It’s indeed an honour to share our work with people from NACI and the minister’s office at DSTI. This really could not have been a better opportune moment for me,” says Prof Matsabisa. 

According to him, he is there to support Prof Nzimande around aspects of traditional medicine as well as with his meeting with the Chinese Minister of Science and Technology during the signing of a letter of intent on traditional medicines including in the BRT conference where the minister will give a talk that will cover traditional medicines. Prof Matsabisa says he is looking forward to strengthening the relationships between the UFS and BUCM and China as well as sharing with the minister the joint projects and joint students from both institutions, hoping for continued support and funding.

“This trip has opened new opportunities. TIA has invited me and the UFS to be part of their new project on neurodegenerative diseases with Cuba. It was wonderful to hear that both the CEO and the chairperson of the board had already been briefed about me to be part of the project.

“It is also great to be present at the signing of the letter of intent on traditional medicine as it is important to know where the policies are heading.”

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.
