Seven supported academics from the Afromontane Research Unit (ARU) on the Qwaqwa Campus saw an increase in their H-indices (Google Scholar) during 2020.

Over the past few years, the university has implemented special interventions to increase the diversity of UFS researchers, including targeted appointments and focused research capacity development and support. Strategic interventions relating to National Research Foundation (NRF) rating resulted in the UFS having a well-established cohort of rated researchers.

According to the recent internal research report, the UFS has 144 researchers in the A, B and C categories (established according to NRF criteria), and 57 researchers under the age of 40 who are considered emerging researchers in the P and Y categories. This brings the total to 201 rated researchers in 2021, compared to 188 in 2020, and 164 in 2019. The university also has 57 Y-rated researchers.

Furthermore, the university submitted 51 applications to the NRF under the 2020 rating call, including 21 first-time applications (of which four were unsuccessful) and 26 who were invited to reapply to keep their ratings active (of which all were successful).

Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, says the UFS has been able to appoint outstanding young researchers over the past eight years. “Not only did these exceptional individuals contribute to our scholarship and research productivity, but they also increased our diversity. The increase in the diversity of our NRF-rated academics is an aspect of the research portfolio that I am most proud of,” says Prof Witthuhn.

Highlighted trends regarding NRF-rated researchers

• There has been a constant growth in the number of rated researchers, from 127 in 2016 to 202 in 2021.
• The majority of NRF-rated researchers (186 in 2021) are from the Bloemfontein Campus. The number of rated researchers from the Qwaqwa Campus increased from 4 in 2016 to 13 in 2021. The South Campus increased its number of rated researchers by two in 2021, with a current total of three rated researchers.
• The Faculty of Natural and Agricultural Sciences has the highest percentage of rated researchers (45%) in 2021, followed by the Faculty of the Humanities (29%).
• The percentage of rated white researchers declined from 92% in 2016 to 78% in 2021, and the rated black researchers increased from 6% in 2016 to 17% in 2021.
• The percentage of rated female researchers increased from 27% in 2016 to 34% in 2021.
• Rated researchers in the C2 and C3 rating categories declined slightly, from 52% in 2019 to 47% in 2021. There is still positive growth in the number of young (Y1/Y2) rated researchers – from 14% in 2016 to 27% in 2021.

Ratings and promotions

The university hosts a total of six South African Research Chairs (SARChI) funded by the NRF / Department of Science and Innovation (DSI), of which four are held by women. Three chairs are appointed in the Faculty of Natural and Agricultural Sciences and the Faculty of Education, while the faculties of Economic and Management Sciences and Health Sciences appointed one chair each. Two research chairs have been renewed for 2021-2025.

Seven supported academics from the Afromontane Research Unit (ARU) on the Qwaqwa Campus saw an increase in their H-indices (Google Scholar) during 2020, while one new Y1 NRF rating was awarded and another was increased to C2 level. Two ARU-supported academics achieved professorial status in the same year.

Twenty-five young academics on the cusp of NRF rating and promotion to the rank of Associate Professor are participating in the Future Professoriate Mentoring Programme, while the 25 participants of the ESAP group have completed their doctorates over the past three years and are working towards obtaining a Y-rating. As a result of the outstanding progress of the first cohort of the mentoring programme during 2020, a second cohort of ESAP scholars was selected in March 2021. More than 80% of the 75 group members are younger than 40 years.

Drs Frans Kruger and Lodewyk Sutton also received NRF Y-ratings in November 2020. The ESAP programme currently has three recipients of the FirstRand NRF Black African Advancement Fellowship Programme: Dr Eugene Baron (Practical Theology), Dr Mirriam Moleko (School of Mathematics and Science Education), and Dr Neo Pule (Psychology). Dr Lizemari Hugo from the School of Nursing also received a FAIMER (Foundation for Advancement of International Medical Education and Research) fellowship. Dr Mikateko Höppener (Centre for Development Support) has been selected to participate in the national DHET Future Professoriate Programme.

Publication output units show significant increase

The publication output units (books, conference proceedings, and journal articles) by UFS researchers, as measured and reported to the Department of Higher Education and Training (DHET), show consistent growth from 2016 to 2020. The output units increased significantly in 2019 and 2020 after a slight decrease in 2017.

There has also been a notable increase in books/chapters since 2018. Journal articles also showed constant growth from 2017 onwards, especially from 2019 to 2020, with a 20% growth in journal outputs visible; however, conference proceedings declined last year.

Main contributors

The faculties of Natural and Agricultural Sciences, the Humanities, and Theology and Religion remain the main contributors to the university’s publication output. Four faculties (Economic and Management Sciences, Education, Health Sciences, and Theology and Religion) increased their share of units in 2020 compared to the 2016-2019 period.

The journal output units generated from scholarly articles published in internationally indexed journals remained more than 80% (82% in 2017, 85% in 2018, 81% in 2019, and 85% in 2020). Only 15% of journal articles were published in South African indexed (DHET) journals (compared to 24% in 2016). Since 2016, there has been a clear shift towards publications in internationally indexed journals.

The following nine in-house journals are being administered by the UFS:

Acta Academica (editor: Henning Melber), Acta Structilia (editor: K Kajimo-Shakantu), Acta Theologica (editor: Jan-Albert van den Berg), Communitas (editor: Willemien Marais), Journal for Juridical Science (editor: Bradley Smith), Journal for Translation Studies in Africa (editor: Kobus Marais), Perspectives in Education (editor: Jan Nieuwenhuis), Southern Journal for Contemporary History (editor: Neil Roos), and Town and Regional Planning (editor: Maléne Campbell).

All are DHET-accredited, except for the Journal for Translation Studies in Africa, a new KovsieJournals title.

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.
