Dr Nicholas Pearce, Head of the COVID-19 Task Team at the Universitas Academic Hospital, leads a dedicated team of professionals at the testing and vaccination site of the Universitas Academic Hospital, adjacent to our Bloemfontein Campus.

It is impossible to quantify the number of hours Dr Nicholas Pearce, Head of the COVID-19 Task Team for the Universitas Academic Hospital, spent working in response to this deadly virus since the first case was reported in South Africa last year. 

According to Dr Pearce, who is the Head of the Department of General Surgery in the Faculty of Health Sciences at the University of the Free State (UFS), the initial preparation phase required many hours of brainstorming, planning, and physical hours working on site. He also spent countless hours awake at night trying to come up with solutions for the many challenges faced along the way. This is in addition to being available telephonically twenty-four-seven for any issues related to equipment, staffing, and facilities.

“I was attending a vascular surgery congress in Germany last year January (2020) when China just announced the outbreak of COVID-19. I noticed an increased number of travellers wearing surgical masks at an airport in the Middle East when I was travelling to South Africa. 

“Upon my return to work, I approached management to discuss procurement of PPEs, as it was just a matter of time before COVID-19 would hit South Africa and the rest of the world. When things escalated, I was asked to head the COVID-19 response team at Universitas Hospital,” explains Dr Pearce.

Dr Pearce, who was brought up to always strive to be better, is driven and motivated to succeed. He has a very analytical brain and loves challenges. In fact, he does not believe in problems and only sees challenges. This kind human being can sometimes seem quite tough on the outside, but actually has a very soft heart. 

“I think it is human nature to want to feel needed. I have an inherent urge to help my fellow human beings. This is also the reason why I became a health-care professional and why I am passionate about teaching,” says Dr Pearce. 

With South Africa lagging behind with its vaccination programme, the hard work is far from over for Dr Pearce and his team. Says Dr Pearce: “The initiation of a mass vaccination site posed a whole new set of challenges, which once again required many hours of planning. The initial stages of running the vaccination site required many hours of physical hard work a day. Then there is also the daily operations meeting at 18:00 every weekday to discuss the vaccine roll-out in the province.”

Frustrations and setbacks

For Dr Pearce, this pandemic highlighted the differences between individuals from different social classes in our country. Providing quarantine and self-isolation facilities for individuals who do not have access to such facilities at home is one such example. 

“We all have a right to clean water and good quality healthcare. This also includes a right to oxygen. This right to oxygen has proved to be one of our great challenges in managing this pandemic. Delivery of these large amounts of oxygen has been especially challenging. Some days we require in excess of five tons of oxygen,” says Dr Pearce.

There have been many frustrations and setbacks on this journey, some of which can be quite demoralising and demotivating, but knowing that he is doing something good for his fellow human beings gives this gentle and diligent healthcare worker a tremendous amount of energy. “Positive feedback from patients and colleagues far outshines all the frustrations and disappointments,” concludes Dr Pearce. 


Outside of work

After finishing online meetings at home, Dr Pearce relaxes with his partner by chatting about the day’s events and cooking supper together while enjoying a glass of wine. He also tries to connect with family who lives in Gauteng. Because of work pressures and the pandemic, he has not been able to see them as much.

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.
