Improving student well-being through collaborative food provisioning initiatives.

In commemoration of Nelson Mandela and his commitment to justice, human rights and fundamental freedoms, a profound belief in the equality and dignity of every woman and man, the University of the Free State (UFS) reflects on the university’s food gardening project, a collaborative initiative established to address student food insecurity in a sustainable manner. 

As stipulated in the 2021 UFS Food Environment task team report, food insecurity among students in the higher education sector has emerged over the past decade as a global threat to student success. According to the internationally accepted definition of food insecurity, these students experience limited or uncertain availability of nutritionally adequate and safe foods or have limited or uncertain ability to acquire acceptable foods in socially acceptable ways.

The UFS Food Environment Office, in collaboration with Kovsie ACT, the UFS Department of Nutrition and Dietetics, FARMOVS, Tiger Brands, Siyakhana Food Gardens and other businesses, has embarked on an 18-month journey to address this problem within the university. 

The project kicked off with the building of two large food tunnels that aid students with fresh produce on a regular but controlled basis. The project has received financial support from organisations including Tiger Brands, Siyakhana Food Gardens, and Sakata Seeds.

A recap of the UFS gardening project and food harvested

The gardens produced foods such as Swiss chard, beetroot, carrots, and cabbage that were consistently distributed to vulnerable students from March 2020 up until now. Onions, lettuce, and spinach also formed part of the food parcels prepared for students, accompanied by food donations from UFS staff and students, Tiger Brands, and the Shoprite Group through the UFS food bank.

In November 2020, a brainstorming workshop was held to reflect on the status quo of the UFS gardening project and the value it adds to a larger integrated food provisioning system at the university. The workshop addressed topics including the planting and production of relevant crops; processing and distribution of products harvested; and the creation of a training curriculum pertaining to the activities of the UFS gardening project.

“By creating our own food gardens, we share valuable knowledge with the rest of the team involved with this project and further uplift our communities. After all, small-scale sustainable food production could lower one’s environmental footprint and contribute to a healthier lifestyle,” stated Carien Denner from the UFS Department of Sustainable Food Systems and Development. 

Denner goes on to explain that the mutually beneficial relationship of all stakeholders involved in the maintenance of the food gardening project has the potential to expand in the future to further combat student food insecurity in a sustainable manner. 

What the UFS food garden project anticipates for the future

According to Denner, the food tunnels at Lengau will be moved to the Paradys experimental farm. One tunnel will be converted into a hydroponic system covered in plastic, and the other will be covered in netting and will be planted directly into the ground. Financial aid for the moving of the tunnels was provided by the UFS Dean of Natural and Agricultural Sciences and Prof Rudolf from the Siyakhana Food Gardens. 

The produce from these two tunnels will be sold to UFS staff and some will be distributed to students through the UFS No Student Hungry Programme (NSH). Denner mentioned that the team are further looking to empower students to grow foods at their own homes by involving them in the planting and harvesting process of the gardening project. 
The continuation of the food gardening project and other support initiatives facilitated by the Food Environment task team thrive through collaborations with businesses, NPOs, UFS staff and students, to address food insecurity and malnutrition among students. 

Staff and students are encouraged to contribute by collecting non-perishable food items for the UFS Food Environment Office.

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.
