Tau Tladi.

In times of great difficulty, a tale of hope goes a long way in encouraging one to persevere. Tau Tladi, a second-year LLB extended-programme student who was diagnosed with ataxia – a degenerative disease of the nervous system – at a young age, has conquered many adversities. He is living his life to the fullest, pursuing his dream of becoming a lawyer one day. Because of a brain injury during birth, Tladi struggles to speak, write, or walk. On campus, he makes use of a scribe and reader to write his tests and exams. 

Learning from others key to success

“Living with ataxia means I have improper speech, I struggle to walk properly, my hands can’t grab things properly, and I can’t even write with them.   Seeing other people living with disabilities and still pursuing their dreams has inspired me a lot; it made me realise that I too have the ability to achieve my dreams,” he said. 
While this disability presented him with many hindrances in life, it has never held him back. “Growing up was challenging because I was not able to develop like other children. As I got older, I could not experience some of the things that other kids could do, such as playing and running around,” he said.

Triumph in the face of adversity
 
Despite all the challenges, Tau completed his matric in 2016 and was even named as one of the top 100 achievers in the Free State. He describes his admission to the LLB programme as a dream come true. “I have always wanted to study an LLB degree. It is the best feeling ever to be at university and studying something that I always wanted to do. I would love to become an attorney.”

Tladi hopes to finish his degree in 2021. He is also an avid sportsman, having participated in the Free State paracycling team and winning first place at the national competition. 

“Living with disability has never been easy for me, so I have learned to be grateful and use every opportunity that I come across and work very hard to fulfil my dreams.”

Hanlie Grobler, Senior Officer in the Faculty of Law, described Tladi as a remarkable young man who always wears a smile on his face. “If you are feeling a bit blue today, cheated by COVID-19, that life is unfair to you – remember this young man who is an excellent example of determination, and do what you have to do, to the best of your ability, and be thankful for what you have.”

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.
