KMUN 2023
Young leaders unite! Fostering diplomacy and innovation – The Kovsies Model UN Summit 2023 shaped future global change makers!

The saying goes, ‘Leaders are born, not made,’ but what term do we use when more than 50 young individuals from various institutions gather to address and tackle many of our global socio-economic issues collectively?

The University of the Free State United Nations (UN) Chapter hosted the first of many Kovsies Model United Nations (KMUN) Summits – a simulation of the UN General Assembly (GA) – from 28 to 30 July 2023. The event brought together students from various institutions, including the University of Pretoria (UP), Wits, North-West University (NWU), as well as the UFS South and Qwaqwa campuses, who convened on the UFS Bloemfontein Campus for this prestigious gathering.

The students represented different countries and embarked on a comprehensive research project focused on the challenges faced by their respective nations and their progress in addressing them, which they had to present at the GA. Their investigations encompassed various Sustainable Development Goals (SDGs), including poverty eradication, building partnerships, promoting quality education, and advancing gender equality. These efforts align perfectly with the university's Vision 130, which is dedicated to promoting academic excellence, fostering social impact, and embracing diversity.

Siphilangenkosi Dlamini, Executive Chair of the UN Association of South Africa’s UFS Chapter and Student Assistant in the UFS Centre for Teaching and Learning (CTL), said that the summit served as a platform to bring together young people and student leaders from participating institutions to address an array of issues as if they were leaders of different countries.

"Our objective was to create a platform where these young minds could participate in constructive dialogues, refine their diplomatic skills, and address urgent global challenges. The most remarkable aspect was observing the participants' passion and dedication. Witnessing them wholeheartedly embrace the principles of diplomacy and cooperation was genuinely uplifting.”

Moreover, the attendees expressed their appreciation for this prestigious event, as it provided them with invaluable information and insights into what the future holds for them.

Keoratile Moloto, a North-West University student who proudly represented Belize – a Central American country – emphasised that this unique experience provided him with a valuable opportunity to acquire knowledge. As a student leader, he believed that this knowledge could positively influence and inspire both those he served and those in leadership positions.

“This is a too exciting initiative to ignore as a young individual who aspires to improve the world. I have always envisioned a time where I can make a difference in a community. I am big on most SDGs and saw this opportunity as a stepping-stone to educate myself on the proceedings. It is an awesome experience to engage with these topics rather than just being a viewer.”

Students were encouraged to collaborate and be active observers of pressing issues that affect their future. Student Affairs Assistant Director, Motlogelwa Moema, also advised the delegates to approach the debates with an open mind, network, familiarise themselves with the SDGs, and develop sustainable, innovative solutions to these socio-economic challenges.

This summit proved to be an enriching and transformative experience for all participants. From engaging in diplomatic negotiations to tackling global issues, delegates developed crucial leadership skills, fostered diplomacy, and shaped the future of international relations. As delegates from prestigious universities came together, the discussions were diverse, thought-provoking, and inspiring. Undoubtedly, the KMUN Summit left a lasting impact on the delegates and contributed to developing future leaders who would make a positive difference on the global stage.

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.
