During the Faculty of Education ceremony, Louzanne Coetzee, a blind UFS alumna and speaker, shared her remarkable journey. From her days as a high school learner to becoming a student, she highlighted her challenges and how she overcame them.

The April graduations at the University of the Free State (UFS) were a remarkable celebration of diversity and inclusivity, with 44 graduates with learning difficulties, visual, mobility, or hearing impairments honoured for their achievements.

Despite facing unique challenges throughout their academic journeys, these resilient students triumphed over adversity to earn their degrees, inspiring their peers and educators alike – all with the assistance of the Centre for Universal Access and Disability Support (CUADS) within the Division of Student Affairs.

Words of advice from the recent graduates

Nkosingiphile Nyanale, who is blind, recently graduated with a Bachelor of Laws (LLB) degree. He emphasised the importance of mutual understanding between students and educators as a way of helping students with disabilities to overcome the extra hurdles they face. “One of the most challenging parts of my journey was reaching a common understanding with some facilitators on how I could be reasonably accommodated in class,” Nyanale said. “Some lecturers would deny themselves the opportunity to understand the challenges of students with visual impairments and viewed my requests as a way of seeking an easy pass. So, peers and lecturers understanding various impairments helped shape my journey.

Sthembiso Dlamini, a BSc Mathematics and Mathematical Statistics graduate who lives with dysgraphia, a condition that creates challenges related to handwriting, spelling, and organising thoughts on paper, said, “In my third year, I struggled to focus during high-stress exams. I willingly sacrificed much of my leisure time to tackle this obstacle head-on. I committed myself to honing my learning methods and enhancing my time-management abilities.” 

Relebohile Moloi, a nursing graduate, thanked CUADS for its help, and said greater awareness of the centre and its services could help more students. “They should assess students regularly for impairments, because sometimes people don’t know they have an impairment. CUADS should visit each faculty to give information on who they are and what they offer.”

The speaker

Louzanne Coetzee, a blind UFS alumna, shared her story during the last graduation session of the season on 20 April. “After matriculating at the Pioneer School in Worcester [Western Cape], where it was a protected environment, I did not know what to expect from the UFS. However, the UFS gave me a conducive environment by allowing my guide dog, Isabel, into the residences. I was the first person to be allowed such.” [Listen to her full speech here.]

Inclusive environment

Martie Miranda, Deputy Director at CUADS, said she’s proud of the graduates, as they embody the UFS’s dedication to an inclusive environment that caters to all its students, in line with the university’s Vision 130, which aims to foster academic excellence in a diverse and equitable environment. “In celebrating our graduates, we honour not just their achievements but the enduring commitment of CUADS staff and the university to foster an inclusive environment where every student's journey is valued and supported."

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.
