A team of exceptional students from the University of the Free State (UFS) has claimed victory in the prestigious SDG Challenge South Africa, a global competition that unites students and organisations to address the United Nations Sustainable Development Goals (UNSDGs). This remarkable achievement not only underscores the skill and dedication of UFS students but also reinforces their commitment to forging a more sustainable and equitable world.

The group of students from different disciplines within the Faculty of Natural and Agricultural Sciences (NAS), came up with an interdisciplinary and forward-thinking approach which contributed significantly to their victory. The team members, including Pieter Bruwer, Dr Anathi Makamane, Dr Brandon van Rooyen (all from Sustainable Food Systems and Development), Daniel Naudé (Department of Agriculture Economics), as well as Dr Yolandi Schoeman (a postdoctoral fellow in the Centre for Environmental Management (CEM) from the Faculty of Natural and Agricultural Sciences, each brought their unique expertise to the challenge.

Prof Jan Willem Swanepoel, Associate Professor in the Department of Sustainable Food Systems and Development within the Faculty of Natural and Agricultural Sciences, provided invaluable mentorship to the team. The students were also supported by Robyn Mellett from OMI Solutions.

Dr Schoeman says the SDG Challenge, designed to confront global challenges, connects students and organisations from across the globe, fostering collaboration towards achieving the UNSDGs, which encompass critical issues such as climate change and the reduction of global inequalities. Teams from South African universities, including the University of Cape Town, Stellenbosch University, and the University of KwaZulu-Natal, partnered with leading companies to address specific challenges tied to their corporate missions.

Develop a waste management strategy

Team UFS joined forces with Ivanhoe Mines, a prominent mining company operating in the Democratic Republic of Congo to develop a waste management strategy for the Kamoa-Kakula Copper Complex. This endeavour was laden with complexities due to the limited waste management options available in the area. The challenge was not just about managing multiple waste streams from the mining complex, but also about addressing socioeconomic and biodiversity challenges stemming from the burgeoning population in the region, which led to a range of environmental concerns.

“In response, the UFS team innovatively conceived ÉcoFlotille, a solution that not only tackled essential waste management issues but also promoted biodiversity net gain. The plan extended its reach to support local agribusinesses and small and micro-enterprises through the repurposing and reuse of waste materials, while presenting a unique biofinancing opportunity. The EcoFlotille solution represents a distinctive aspect of their triumphant journey.

“ÉcoFlotille not only aligns with the SDGs but also plays a crucial role in realising the vision of the Kunming-Montreal Global Biodiversity Framework, which emphasises the conservation and sustainable use of biodiversity. Additionally, it aligns with the goals of Agenda 2063 for Africa, striving to advance the continent’s development objectives and create a prosperous and harmonious future for the region,” says Dr Schoeman. 

The scalability of ÉcoFlotille across Africa holds great promise. Its innovative waste management approach and biofinancing potential could serve as a model for addressing similar challenges in diverse regions of the continent. This opens up opportunities for wider adoption and positive impacts throughout Africa.

Creating a more sustainable and equitable world

The SDG Challenge South Africa is an integral part of Soapbox’s global mission to mobilise university students and organisations in working collaboratively toward the UNSDG. These goals aim to address the world’s most pressing challenges, requiring collective efforts to achieve sustainable economic growth, environmental sustainability, and social inclusion by 2030.

The UFS’s remarkable success in the SDG Challenge not only highlights the university’s dedication to fostering global citizenship and sustainability but also underscores the remarkable potential of its students in driving positive change in Africa and the world.

According to Dr Schoeman, the UFS team’s victory in the SDG Challenge stands as a testament to their unwavering commitment to creating a more sustainable and equitable world. Their innovative solution, ÉcoFlotille, serves as a beacon of hope, illustrating how the vigour and ingenuity of the younger generation can propel us closer to realising the UNSDG by 2030, effectively ticking all 17 SDG boxes.

Solving a real-world problem

Prof Swanepoel says the SDG Challenge is a global competition that unites students and organisations to address the UNSDGs. These goals encompass some of the most pressing challenges facing our world today, such as climate change, poverty, and inequality.

According to him, by participating in the SDG Challenge, the UFS students had the opportunity to apply their knowledge and skills to solve a real-world problem experienced by one of the biggest mining houses in the world. They gained valuable experience in collaborating with the private sector.

“I am immensely proud of the students' achievement in the prestigious Soapbox SDG Challenge South Africa. Their interdisciplinary approach and forward-thinking mindset are a testament to the calibre of education and mentorship they receive at the UFS,” Prof Swanepoel says. 

“Furthermore, I am confident that the skills and experience gained through the SDG Challenge will help the students to make a positive impact on the world. They are the next generation of leaders who will be responsible for addressing the complex social and environmental challenges Africa face. I also believe that coming out as victors in this competition would open more doors for them and the university in the private sector.”

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.
