Dr Jared McDonald
Prof Jared McDonald, Assistant Dean: Faculty of The Humanities at the University of the Free State, obtained his first National Research Foundation rating in the C2 category.

Obtaining his first National Research Foundation (NRF) rating has been the goal of Prof Jared McDonald, Assistant Dean: Faculty of The Humanities at the University of the Free State (UFS), since 2020 when he was selected for the UFS Transforming the Professoriate Mentoring Programme.

Prof McDonald obtained a C2 rating recently and credits the programme, under the leadership of Dr Henriëtte van den Berg, who provided invaluable support and mentorship, for this achievement. This rating recognises Prof McDonald as an established researcher and he may enjoy some international recognition for the quality and impact of his recent research outputs. 

“I am delighted to have received a C2 rating. I was hoping to obtain a C2, so when I received confirmation, it felt really good. Since being recruited to the Transforming the Professoriate Programme I have been focused on producing a series of quality journal articles, and importantly, my first monograph. At times it was a struggle to balance the demands of being Assistant Dean in the Faculty of Humanities along with my teaching responsibilities,” says Prof McDonald.

He says obtaining the rating would not have been possible without the interventions of the programme, which assisted him in securing funding for a sabbatical. The encouragement of colleagues and family was equally valuable in helping him to keep his eye on the goal.


Research 

As a nineteenth-century historian, Prof McDonald’s, who is an Associate Professor in the Department of History, research includes topics ranging from the London Missionary Society’s missions to the San as well as the role of controversial missionaries in influencing public discourse on the right to legal equality and social inclusion for indigenous subjects of the British Crown. Another topic is the ways in which evangelical-humanitarian discourse inadvertently provided the justification for the transfer of San children to Cape colonial society. 

“In my publications, the key actors, including Khoesan, are revealed to have been exercising agency in response to a social and political context that was not of their own choosing, but to which they had to respond. The contradictions of the period, coupled with the prospects for blurring the social boundaries of an otherwise strict hierarchical society, provided the means for social manoeuvre and options for resistance from within the confines of the colonial state. I am continuing to explore these ideas in a series of upcoming journal articles and book chapters,” he says. 

The pressure, says Prof McDonald, is already on to retain his rating, and hopefully improve it, when it comes up for review in five years’ time. He is currently working on his second monograph, which is a historical biography of a controversial, but fascinating, missionary who played a notable role in South African history in the early nineteenth century. “The worth of any historical biography lies in the biographer’s ability to shed light on the circumstances, contingencies, and contradictions that shaped the contours of the protagonist’s life, thus illuminating the historical context,” concludes Prof McDonald. 

He seeks to relate his research to his approach to teaching by exploring innovative ways of making the past relevant to students today. This is motivated by the conviction that the elucidation of possibilities of agency in the past raises the prospect for students to engage with the meanings and possibilities of agency in the present.

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.
