Dr Victor Gwande

Attaining his master’s degree cum laude, completing a PhD degree, and publishing in top academic journals, University of the Free State (UFS) academic, Dr Victor Gwande, has been an outstanding researcher throughout his career.

Adding to his list of notable achievements, the postdoctoral research fellow in the International Studies Group has just been awarded a fellowship at Princeton University, one of the top universities in the world. The US institution was recently ranked sixth in the Times Higher Education World University Rankings 2020.

As a fellow of the Institute for Advanced Study at Princeton, Dr Gwande will spend two weeks on the Ivy League university’s New Jersey campus in 2020. This will be followed by a weeklong session at one of two collaborating institutions in South Africa and the US, with continuous communication facilitated among selected scholars throughout a two-year period. 

Flying high the flag of the African academy
Dr Gwande believes the fellowship will expose him to new intellectual traditions and perspectives. “It will help me create international academic networks across continents, as I seek to put my name out there as an internationally recognised scholar.”

With his research interests in economic and business history of Southern Africa, Dr Gwande says he wishes to become “a great scholar of African economic history, flying high the flag of the African academy, as well as training and producing young scholars for the academy”.

Working with some of the world’s top minds at Princeton University, there will be much to focus on.

“I will be researching, writing, and presenting my research project in which I use the case study of the Anglo American Corporation to look at the histories of capitalism and to understand how monopoly capitalism shaped economic trajectories of Zimbabwe and the broader Southern African region.”

Longer-term plans include completing his monograph stemming from his PhD thesis.

There are many people to thank for his journey from the UFS to Princeton, and the scholar draws attention to some of those who have influenced him. 

“God and my family. But in my career, quite a number of people and institutions have really moulded me; the International Studies Group under Prof Ian Phimister has given me an environment to flourish in my young career.

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.
