“Running provides me with a platform to reach others, to bring hope, to make people realise that anything is possible if you are prepared to work hard for it,” says Louzanne Coetzee, our very own home-grown all-round achiever, who is fun-loving, relatable, and inspiring. A South African para-athlete, Coetzee was born blind as a result of a hereditary condition called Leber congenital amaurosis, and competes in the T11 disability class for athletes with the highest level of visual impairment. Coetzee enjoys an integrated life, with an interest in baking, watching movies, walking and hiking, cycling, being part of a church band, public speaking, coupled with some artistic hobbies.

Our podcast guest

Coetzee competed at the 2020 Tokyo Paralympic Games this year, where she won a silver medal in the 1 500 m final alongside her guide Erasmus Badenshorst, setting a new African record of 4:40.96. She also competed in the women’s mixed class marathon (T11 and T12 for the visually impaired) with her guide Claus Kempen, improving the world record by 1 min 42 sec and her personal best from 3:13:41 to 3:11:13. 

In 2018, Coetzee competed in three events at the Para Athletics event in Berlin, Germany – the 800 m, 1 500 m, and 5 000 m. She set a new African record in the T11 800 m race, taking the silver medal, as well as a bronze for the 1 500 m race. In 2018, Coetzee also broke the 5 000 m (women) world record in her disability class, while in the same year she became the first visually impaired athlete to compete at the World University Cross Country Championships in Switzerland. 
Coetzee set a new world record in the 5 000 m T11 category for the first time at the Nedbank National Championships for the Physically Disabled in March 2016. Moreover, with her performance of 19:17.06, Coetzee shattered the Lithuanian athlete Sigita Markeviciene’s 16-year record of 20:05.81, set at the 2000 Paralympics in Sydney. Coetzee became the first totally blind female to clock sub-20 minutes in the 5 000 m.

Her involvement in her society stretches beyond sports, and as a student, she formed part of the University of the Free State Student Representative Council. She was also an athlete representative on the Free State Academy of Sport’s executive committee.

In 2014, she became the first visually impaired student to be elected to the UFS Student Representative Council (SRC), with the portfolio Student Accessibility. From 2015 to 2017, she was a research assistant in the Institute for Reconciliation and Social Justice at the UFS, and in 2016 she also acted as junior lecturer in a computer module for students with visual impairments. From 2017 to 2018, she was Residence Head of Arista Ladies City Residence, and she is currently the Residence Head of Akasia Residence at the UFS.  

Coetzee boasts several accolades from the UFS. She was named the 2014 Senior Sportswoman of the Year by the Free State Sport Association for the Physically Disabled (FSSAPD). In 2017, she and her guide Khothatso Mokone received a Special Award for Disabled Sport at the KovsieSport Awards. In 2018, she won the Free State Sports Star Award, and was named Sports Star of the Year (period June 2018 to April 2019) by the Free State Sport Association for the Physically Disabled. 

Coetzee’s academic qualifications include a BA and BAHons in Integrated and Corporative Marketing Communication, and an MA in Social Cohesion and Reconciliation – all from the University of the Free State.

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series.  Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021.  Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

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.
