Vicky Simpson believes our current reality is temporary and that we are more than capable to adjust, regardless of our understanding of what ‘normal’ is.

Vicky Simpson is Development Officer in the Office for Institutional Advancement at the university, where one of her main focus areas is to secure funding for UFS projects and raising funds for student bursaries and the No Student Hungry Programme. 

Simpson, an energetic and proactive person who has a passion for interventions that are humanitarian in nature, says she considers herself lucky to be able to align that which she is passionate about with her career, where she can promote the greater good and create opportunities for others.

“I love working with people and I draw energy from interpersonal interactions. I am an extrovert.”

But the strict lockdown regulations implemented by government in March due to the COVID-19 pandemic, which limited personal interaction – dampened Simpson’s enthusiasm for life.

“The side effect was constant snacking – given that the fridge was next to my temporary office. My energy took a dip and I gained weight.”

Keeping positive

“My partner being a frontline medical worker added additional challenges, given that we had to implement strict routines to keep COVID-19 out of our home. We were both rather drained and had to find ways to keep each other positive.”

Practical as she is, Simpson determined that she craved interaction and fresh air.

“I decided to do video calls with friends and family. This made up for the lack of social contact.”

For fresh air, Simpson started a light exercise routine once South Africans were allowed to go for walks, and gradually increased it. “Exercise and healthy nutritional choices lifted my mood. Basically, I used my time wisely and decided to change my routine for the better,” Simpson adds.

She says the key is to set small goals and to take things slowly. “One small victory at a time.” 

Healthy choices

The pandemic challenged Simpson to embrace a more active lifestyle. “The situation forced me to do introspection, self-care, and nurturing,” she says.

Her advice to others is to make the tough choices. “It is easy to get caught up in a routine where you can’t find the time to go for a walk. Evaluate your routine. Start slowly. And do not forget to drink lots of water, take your vitamins, and eat healthier,” she adds.

Simpson explains that she started off by walking only 30 minutes every second day. But once the serotonin bug bit her, she was hooked. Now she goes for a 5 km run at least once a week. “I simply want to feel healthier again,” she says.

She believes our current reality is temporary and she is looking forward to life after lockdown. 

And what is she looking forward to most? Seeing other people smile. “Yes, I randomly smile at strangers. They always smile back. There is not enough love in this world and small things go a long way,” she says.

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.
