Prof Francis Petersen
Prof Francis Petersen, UFS Rector and Vice-Chancellor opened the workshop on Monday, 10 February 2020.

Will an enclaved state work in a country like South Africa? How can universities produce graduates who will become engaged citizens, and what is the current status of the ANC and the DA? These were some of the key topics at a workshop on South Africa and Africa: Prevarication at the Precipice, hosted by the Department of Political Studies and Governance at the University of the Free State (UFS). 

The two-day workshop is an annual collaborative discussion platform between the UFS, chaired by Prof Hussein Solomon, the Southern African Centre for Collaboration on Peace and Security, and the Osaka School of International Public Policy

The workshop opened with Prof Francis Petersen, the UFS Rector and Vice-Chancellor who delivered his message from the perspective of higher education. 

He spoke about the importance of universities in South Africa being able to produce graduates who will become active citizens. 

Graduates should fulfill their role in society 

“Universities should be the place where we should educate and engage to let our students and graduates know what society should look like. If we don’t do that transformative thinking among our graduates we are going to perpetuate what society is,” Prof Petersen said. 

“I hope this conference won’t just debate the issues because we already know the answers. I hope this workshop will say what we need to do as active citizens to ensure that we start new building steps. International engagement is also important. As is our engagement with the continent.” 

Helen Zille on the State of South Africa 

Helen Zille, Chairperson of the DA Federal Council presented a talk on the State of South Africa in which she tabled three variables she believes can save the country from the precipice. “There should be three variables which can make a democracy work; a separate state (not a party-ruled state), the rule of law and a culture of accountability,” Zille said. 

Zille tabled the concept of an enclaved state a state which operates independently from party control. “There are increasingly isolated states in SA which are being pushed out of good governance and service delivery. An example of an enclave that functions well is the “justice enclave (Supreme Court of Appeal) in Bloemfontein”. 

She reiterated the importance of active citizenship. However she added that people who are active citizens are usually not the ones elected to office.

The role of active citizenship and the state of the country cannot be discussed in isolation from the state of the ruling ANC and the official opposition, the DA. Prof Dirk Kotze from the Department of Political Studies at Unisa, and Bonolo Selebano, Netwerk 24 political journalist, gave a glimpse into the status of Luthuli House (ANC headquarters in Johannesburg), and the DA. 

“ANC party politics are not unique. They are following a global trend. However, the credibility of the ANC is a big issue,” said Prof Kotze. In the political arena globally, political parties are redefining themselves and it is important for the ANC to figure out where it finds itself. Selebano wasn’t too optimistic about the DA either, saying the party should return to its liberation ideals.

Research helps farmers save with irrigation

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.
