BUAN Delegates
Botswana University of Agriculture and Natural Resources (BUAN) delegates that recently visited the University of the Free State to solidify a collaboration.

During an inspiring journey, a delegation from the University of the Free State (UFS) recently visited the Botswana University of Agriculture and Natural Resources (BUAN) with an ambitious goal: to solidify a collaboration that was sparked during the visit of BUAN’s Vice-Chancellor to the UFS and subsequent discussions in Namibia. The atmosphere was one of shared purpose and excitement as the UFS representatives, led by the Dean of the Faculty of Natural and Agricultural Sciences, the Vice-Dean: Agriculture, and the Vice-Dean: Postgraduate and Research, embarked on this significant academic endeavour.

This visit was not just a formal gesture, it was a step towards tangible, mutual benefits for students and staff of both institutions. The discussions between the UFS and the BUAN leadership, which centred around possibilities for student and staff exchanges and shared access to specialised equipment, pointed to the potential of creating a dynamic bridge between South African and Botswana academia. This partnership envisions collaborative supervision of postgraduate students, creating opportunities for intellectual growth that transcends borders. The two universities also explored joint funding applications and research avenues, with particular interest in BUAN’s innovative Meat Institute and AgroVolts solar panel project. Seeing the BUAN’s progress in renewable energy left the UFS team particularly impressed, reflecting the possibilities for sustainable development and resource-sharing that a partnership could yield.

During the discussions, the UFS delegation had a pivotal meeting with the BUAN’s Acting Deputy Vice-Chancellor: Academic and Research, Prof Samodimo Ngwako, who had previously visited the UFS. His familiarity with the UFS’ resources and vision made him an invaluable advocate for bridging the two institutions, highlighting how their strengths could complement each other. Prof Ngwako’s insights helped BUAN staff visualise the meaningful exchange of expertise and resources that could benefit both student bodies and contribute to third-stream income generation.

With the way forward clear, both the UFS and BUAN teams agreed on ‘quick steps’ to launch the collaboration – the swift signing of a Memorandum of Understanding (MoU), followed by the first exchange of students and staff, and the launch of co-supervised research projects. While specific timelines and milestones are to be confirmed post-MoU, both teams are keen on joint funding applications, especially in areas relevant to agricultural and natural resources both within Africa and beyond. This partnership, once formalised, is expected to solidify both universities as leading research hubs in agriculture and natural resources, advancing each institution’s standing on the continent.

Reflecting on the visit, the UFS delegation felt a deep sense of optimism. The collaboration between the UFS and the BUAN aligns seamlessly with the UFS’ broader vision for strengthening ties with African universities, showcasing a forward-thinking approach to partnerships. As the journey towards meaningful collaboration progresses, the shared enthusiasm witnessed at the BUAN serves as a hopeful reminder that academia – when united by common goals – can drive impactful change for students, faculty, and communities on both sides of the border.

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.
