The University of the Free State, through its Free State Centre for Human Rights, is pleased to present an online panel discussion titled, The Gaza crisis: How should South African universities engage with ‘pressing and urgent injustices’?

Following the killing of 1 143 people and the taking of 247 hostages by Hamas during an armed incursion in Israel on 7 October 2023, Israel mounted an invasion of the Gaza Strip. In the ensuing bombardment and ground offensive – which is continuing ten months after the Hamas attack – Israel armed forces have killed more than 38 000 people. Hamas’ killing and continued holding of hostages and Israel’s sustained offensive – described as an ‘unfolding genocide’ and a ‘massacre’ – confront universities with an enduring question: how to engage as institutions ‘with pressing and urgent injustices’?


Join us for an online panel discussion where pertinent questions emerging from the current crisis will be discussed. Should a university such as the University of the Free State formulate an institutional response to the Gaza crisis? If so, what form should it take? Is a statement, as has already emanated from several other South African universities, appropriate and sufficient? How to deal with current ties with Israeli universities, businesses, and individual academics? Can the UFS remain silent?

For South African universities, the Gaza crisis is a particularly apt lens through which to consider this question. Firstly, because Israel’s invasion of Gaza also manifested as a ‘scholasticide’: a large-scale destruction of schools, universities, and other places of learning in Gaza and the killing of Palestinian teachers and academics. Secondly, because of the strong historical and current links between South Africa, Palestine, and Israel: Israel’s past collaboration with the South African apartheid regime; the South African liberation movement’s enduring relationship with Palestinian liberation; and the many uncomfortable congruences between South Africa’s history of racially determined injustice and the current ethno-/racial social, political, and geographical segregation in Israel/Palestine.

Moderator

Prof Francis Petersen: Vice-Chancellor and Principal, UFS. 

 

Speakers
Prof Kistner has held teaching positions in Comparative Literature at Wits University, Modern European Languages at Unisa, and Philosophy at the University of Pretoria and is an extraordinary professor in the University of the Free State Department of Public Law. She is currently working on intersections between political philosophy, social theory, jurisprudence, and psychoanalytic theory.

Prof Nieftagodien is the NRF South African Research Chair in Local Histories and Present Realities and is the Head of the History Workshop at the University of the Witwatersrand, where he also lectures in the Department of History. He is the co-author – with Phil Bonner – of books on the history of Alexandra, Ekurhuleni, and Kathorus, and has also published books on the history of Orlando West and the Soweto uprising, and co-edited a book on the history of the ANC.

Prof Gillespie is a political and legal anthropologist with a research focus on abolition in South Africa, particularly concerned with the ways in which criminal legal processes become vectors for the continuation of apartheid relations. She joined the Department of Anthropology/Sociology at the University of the Western Cape in 2018, prior to which she worked for a decade at the University of the Witwatersrand (Wits). In 2008, she co-founded the Johannesburg Workshop in Theory and Criticism (JWTC), an experimental project tasked with recrafting the work of critical theory beyond the Global North. She writes and teaches about urbanism, violence, sexualities, race, and the praxis of social justice.

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.
