Dr Karen Venter
Dr Venter received her PhD at the December graduation ceremonies. She focused on addressing societal challenges through the practice of engaged scholarship in community-university research partnerships for the common good.

When asked what inspired her to pursue a PhD, Dr Karen Venter, Head of the Division of Service Learning in the Directorate Community Engagement at the University of the Free State (UFS), said she wanted to make a difference in addressing societal challenges through the practice of engaged scholarship in community-university research partnerships for the common good. 

“Also, I love to learn and share knowledge – and that is exactly what I did in this PhD, titled: An integrated service-learning praxis approach for flourishment of professional development in community-higher education partnerships.” 

She explains, “My five-articles-style thesis explored the contribution of an integrated service-learning praxis approach towards the flourishment of engaged scholarship in community-higher education partnerships. The approach combined community engaged service-learning (CESL), appreciative inquiry and appreciative leadership, to advance the praxis of engaged scholarship. The study was demarcated in the field of higher education, applied in the discipline of nursing education, and contextually bound to three interrelated action research cycles and settings – for international, national, and local level engagement.”

Community members participate in the research journey

“The intent of the study was to recognise the community-led action learning of community member participants at the core action learning set,” says Dr Venter. 

The study followed a participatory action learning and action research methodology. During her research journey, she was joined by members of the community, specifically from Bloemshelter – a shelter for the homeless. “They co-constructed and completed a four-year community-led action learning pathway to holistic development (spiritual, personal, professional), which brought about holistic social change and well-being in their livelihood, moving from dependence on others to establishing viable multiple micro-enterprises,” she says.

The UFS affiliated with GULL to reward the community member participants’ action learning. “Already in 2019, GULL certified their action learning with a Professional Bachelor’s degree, while I still had to document the action research, and only now received the PhD,” says Dr Venter. 

“I am grateful to all the participants who co-created action-oriented knowledge with me in the study, from international, to national, to local level of engagement.”

Integrating a PhD with work and life

A PhD requires a lot of hard work and effort, to the point that the lines between studies, work, and life become blurred. Dr Venter acknowledged that she tried to balance work/life and study, but “I was not very good at it”. 
Passion, patience, peace, perseverance, positivity, and prayer are good principles to maintain when you are in the process of completing a PhD. – Dr Karen Venter 

She elaborates, “Studying became an integrated part of my work and life.  For the duration of my studies, I started working at 03:00 and I also did not watch any television.” She did, however, make time for herself by joining the wellness workout programme presented by the UFS, enjoyed gardening, and playing with her grandchildren. “I also tried to rest one day over weekends, and made time to praise and worship, which energised me for the next week,” she adds. 

“Passion, patience, peace, perseverance, positivity, and prayer are good principles to maintain when you are in the process of completing a PhD, she believes. 

Dr Venter says that although writing a PhD is indeed lonely, it is also an exciting journey, “especially when you reach those moments of breakthrough that can only come to life after deep reflection.” She also describes it as a deep spiritual journey. “Almost like walking in and out of a labyrinth – and where many hours become equal to a breath.

She is very grateful to her supervisors, Dr Somarie Holtzhausen, Prof Mabel Erasmus, and Dr Elanie Myburgh. “I deeply honour and salute you for your unconditional and continuous coaching, compassion, and care – guiding, supporting, motivating, mentoring, and keeping me grounded until I completed the journey.”

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.
