A packed Odeion Auditorium at the University of the Free State was welcomed by Professor Helena van Zyl, Head of the UFS Business School. The reason being, a panel discussion with award-winning investigative reporter and author, Pieter-Louis Myburgh, on his much-publicised book Gangster State: Unravelling Ace Magashule's Web of Capture. The programme took the form of a panel discussion. The panellists included Pieter-Louis Myburgh, author; Jacques van Wyk from the Association of Certified Fraud Examiners (ACFE); Cathy Dlodlo, news editor from OFM; Alta Vermeulen from the UFS Department of Political Studies and Governance; and Pieter Roux from the UFS Business School.

In his introduction, Myburgh said he was happy that he was able to come to Bloemfontein and have the discussion, since South Africans should cherish freedom of speech and a free press.

The research for the book took 13 months to conclude, and during this time he spent a lot of time in the Free State and Bloemfontein. He mentioned that the book gave him the opportunity to present a condensed account of what he discovered; he could therefore share more, as opposed to just reporting on a story in the newspaper. For him, investigative reporting should always be fact based and open to scrutiny.

Some of the topics raised by the panel was concern about the perception that investigative journalists are focusing more on corruption in the public sector and less on the private sector. This was, however, discarded as a myth, as Myburgh pointed out that he exposed both private and public sector dealings in order to provide the full scope of involved parties.

Focusing on whistle blowers, the panel challenged the verification of whistle-blower information. Myburgh responded that journalists never use only one whistle-blower’s evidence, since that is merely the start of the investigation. Further investigation was necessary, and facts had to be verified. With that said, there is still a lot to be done with regard to the protection of whistle-blowers, he concluded.

The floor was opened to the audience, which provided the opportunity to ask questions and raise concerns about what was mentioned during the panel discussion. The audience eagerly participated in the discussion. In conclusion, Myburgh reiterated that society plays a vital role in keeping those in power to the promises they make.

After the discussion, the audience had the opportunity to have their books signed by the author.

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.
