Study Bug Bites Historian Early
Prof Corene de Wet, South Campus researcher, is a dedicated historian and educator.

From a childhood dream of being a historian, to a decades-long educator and double doctorate-holder, Prof Corene de Wet has led an eventful life. Realising that her undergrad qualification on its own would not get her a job, she completed the Higher Diploma in Education at the then Potchefstroom University for Christian Higher Education. However, “just to buy some time for myself,” she decided to study part-time while teaching in Winburg.

Prof De Wet calls it “being bitten by the part-time study bug.” By 1991, she had obtained her BEd (an honours degree at the time), MEd, and DEd degrees. In 1999, she graduated with a PhD in History. Today, Prof De Wet is still a research associate on our South Campus.

Tremendous milestones and mentors

Dr Lynette Jacobs, co-researcher on several projects, says, “Prof De Wet was the first woman to receive a full professorship in the Faculty of Education, and the first woman in the faculty to obtain an NRF rating. She received her professorship at a time when the academic world belonged to men. She outclassed her peers, rising head and shoulders above the crowd.”

Prof De Wet says her superhero is Prof Daniella Coetzee, South Campus Principal and long-time colleague. “Prof Coetzee is a brilliant academic and organiser. She makes every member of her staff feel special. I am ever thankful that she saw the need for a researcher on the South Campus and that she appointed me in this position,” says Prof De Wet.

“She is a seasoned academic who
still enjoys international recognition.”

Generational history and work ethic

Although much has changed in education since her initial research, Prof De Wet believes that both her doctoral dissertations still bear scrutiny. Regarding the zeitgeist and its impact on the written history of a nation, Prof De Wet says, “We regularly hear many voices today who say that history must be ‘rewritten’. My thesis dealt with exactly that: How different generations of historians wrote histories influenced by the spirit of the time, or by textbooks, or by their own political or world views, or their philosophy on life. Thus, different generations interpret the same events differently.”

During a career spanning more than four decades, Prof De Wet has upheld a strong work ethic. This has enabled her to maintain her C-rating as an NRF researcher. “If one doesn’t dare, if you are too afraid of critique or failure, you won’t get anywhere in academia,” she says, adding, “Criticism is part of academic life. Therefore, take chances, and learn from healthy, constructive criticism.”

Well-established root system important for sustainable production in semi-arid grasslands

The importance of a well-established root system for sustainable production in the semi-arid grasslands cannot be over-emphasised.

A study of Prof Hennie Snyman from the Department of Animal and Wildlife and Grassland Sciences at the University of the Free State is of the few studies in which soil-water instead of rainfall has been used to estimate above- and below-ground production of semi-arid grasslands. “In the past, plant ecological studies have concentrated largely on above-ground parts of the grassland ecosystem with less emphasis on root growth. This study is, therefore, one of the few done on root dynamics in drier areas,” said Prof Snyman.

The longevity of grass seeds in the soil seed bank is another aspect that is being investigated at present. This information could provide guidelines in grassland restoration.

“Understanding changes in the hydrological characteristics of grassland ecosystems with degradation is essential when making grassland management decisions in arid and semi-arid areas to ensure sustainable animal production. The impact of grassland degradation on productivity, root production, root/shoot ratios, and water-use efficiency has been quantified for the semi-arid grasslands over the last 35 years. Because of the great impact of sustainable management guidelines on land users, this study will be continuing for many years,” said Prof Snyman.

Water-use efficiency (WUE) is defined as the quantity of above- and/or below-ground plant produced over a given period of time per unit of water evapotranspired. Sampling is done from grassland artificially maintained in three different grassland conditions: good, moderate, and poor.

As much as 86, 89 and 94% of the roots for grasslands in good, moderate and poor conditions respectively occur at a depth of less than 300 mm. Root mass is strongly seasonal with the most active growth taking place during March and April. Root mass appears to be greater than above-ground production for these semi-arid areas, with an increase in roots in relation to above-ground production with grassland degradation. The mean monthly root/shoot ratios for grasslands in good, moderate, and poor conditions are 1.16, 1.11, and 1.37 respectively. Grassland degradation lowered above- and below-ground plant production significantly as well as water-use efficiency. The mean WUE (root production included) was 4.79, 3.54 and 2.47 kg ha -1 mm -1 for grasslands in good, moderate, and poor conditions respectively.

These water-use efficiency observations are among the few that also include root production in their calculations.
