Thokozane Ngcongwane recommends that students and staff should actively seek help for their mental-health challenges.

My name is Thokozane Ngcongwane. I coordinate the UFSS1504 module in the Centre for Teaching and Learning (CTL). The journey of struggles and triumphs against mental illness has often peppered my life more than I thought. Having grown up in rural Free State, it was hard for my parents, as well as those around me, to believe that things such as mental illness exist – let alone their own son! 

I grew up with attention-deficit / hyperactivity disorder (ADHD) and was admitted numerous times as the illness was misdiagnosed and untreated. This laid the foundation for a childhood filled with amazing feats of energetic activity, but also had the downside of being misunderstood, or ill-treated due to this illness. Before I knew about this illness, I believed that because of my height (I have been given the names ‘Napoleon’ and ‘Goliath’ by various people, throughout) and stature. I was a prime target for bullying. 

Fast forward to university, and with the world as my oyster, I believed I would do well, graduate, and become the scientist I have always dreamed of becoming. Nothing could prepare me for the roller-coaster ride that, even to this day, has taught me highly valuable life lessons that I would never have received anywhere else. I started a degree in Chemistry (Extended) and was doing well in the first year. I was even fortunate enough to be selected for the F1 Leadership for Change exchange programme that took me to the USA. That was an incredible experience. Fast forward to my third year, and things took a turn for the worse. 

By 2013, I started getting panic and anxiety attacks, the origin of which was quite unknown to me at the time. I thought that I was starting to go insane and this caused a huge drop in my academics, as well as distorting my overall view on life. I started refusing to see friends and family and even shunned myself from engaging in academics. This was the start of my battles and little prepared me for the fight ahead. I took a trip outside of my surroundings and became aware of how the people I avoided cared for me, and the result was that I overcame anxiety for that period. Family, friends, and lecturers were supportive and encouraged me to do my best amid this unknown period in my life. My academics improved and I became social again. 

When I thought the worst was behind me, I was diagnosed with generalised anxiety disorder (GAD). I contacted Student Counselling and Development and received professional assistance. I started feeling better again and was on my way to graduating, albeit the journey was fraught with anxious moments. My graduation was delayed due to a credit shortfall, and this threw me in the deep end once again. This time, I dealt with it better by engaging myself in my passions – sports and the outdoors. I graduated in May 2016 and secured a temporary job as a Science teacher.

I returned home to the Qwaqwa Campus, where I became an intern in CTL. My troubles reached a boiling point in 2019, and I contacted Careways on recommendation of my head of department. It is now 2020, the year of global anxieties. I have learnt that institutions such as the South African Depression and Anxiety Group (SADAG) are available to help. Higher Health is also available to deal with issues around stigmatisation. In short, seek help and never abandon your support structures. Your mental health matters.

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.
