Anton Roodt

 The Afrikaans words, weerlose meganika, can be roughly translated as ‘vulnerable mechanics’. If you do not know the exact meaning of this, rest assured, you are not alone. At least one person does. Anton Roodt of Roodt Architects has been summoning a storm of positive reviews in the literary world with his debut offering, which is neither an environmentally friendly building nor creative historical restoration for which he is renowned, but a book.

Weerlose meganika was written as part of the requirements for Roodt’s fourth MA degree – all obtained at the University of the Free State (UFS), where the Roodts have been part of the UFS family for three generations. Anton’s father was the Head of the department of Architecture, and his son recently completed his studies in the same department. His wife, Zarine, has been involved as lecturer and research fellow in the Department of Communication Science. Roodt’s wide spectrum of interests shows in the variety of his MA degrees (Architecture, Town and Regional Planning, Environmental Management, and now – Creative Writing).

Roodt, renowned for his creativity and innovative manner of working, has barely stepped into the world of literature; yet the book, published by Tafelberg Publishers, is being described in words probably never used by critics: “verrassend vernuwend” (surprisingly refreshing), “baldadig,” (which I can only translate as ‘wildly playful’), and nostalgic science fiction.

In a Zoom conversation, Roodt shared that he wrote mostly in his spare time. Many hours of study in the buzz of architecture classrooms taught him to focus anywhere and anytime. According to Roodt, the chapters that had to be removed in the final edits of Weerlose meganika comprise sufficient material for a second book. 

Anton and his son, Leon-Pierre, both worked on the cover of Weerlose meganika: Anton designed it and Leon-Pierre was responsible for the graphics. Although publishers usually prefer to appoint their own designers, Tafelberg liked and kept the design as presented. This was no surprise, as design is not new to Anton who, as a student, was involved in the design of rag posters. During a particular rag, he realised that the poster design was extremely successful, as about 90% of them were stolen by students from lampposts and other areas. 

Roodt’s recipe for success? He is naturally curious and wants to learn more about many things. This allows him to connect with interesting people such as his fellow students and lecturers (Dr Francois Smith and Prof Henning Pieterse) in the Creative Writing course, where they kept on pushing each other to improve their work. It is clear that Roodt is on a lifelong journey of learning. And, in case you are wondering – yes, he recently started his PhD studies. At the UFS, of course.

When I asked Anton about the strange title, Weerlose meganika, he explained that he has always been fascinated by juxtapositions. He loves bringing seemingly unrelated elements together. 

Looking at the reviews, he has been successful once again. 

*** If you are curious to know more, Weerlose meganika is available at most bookstores, as well as online.

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.
