“Have we — have I — thought sufficiently about the deeper and sacred meaning of everyday life?” Intriguingly, this was how Prof Jan-Albert van den Berg concluded his inaugural lecture on 28 March 2019. During this journey, Prof Van den Berg took his listeners via the scenic route, starting with a mere outline of the divine — first a sketch, then a drawing, until a fully-fledged painting emerges — ending with a manifestation of glory as seen by each individual.

Faith in popular culture

“Practical theology,” said Prof Van den Berg, “implies a specific sensitivity and feeling for the description and meaning of practice and praxis. The use of narratives is one possible way of understanding and documenting a specific involvement in praxis.”

As an object lesson from popular culture, Prof Van den Berg cited the now-infamous-yet-ultimately-beneficial amateur restoration of the Ecce Homo by octogenarian Cecilia Giménez in Borja, Spain. The original fresco, ‘Behold the Man’, was painted in 1930 by Spaniard Elías García Martínez. By 2012, the artwork had suffered the ravages of time, until Giménez’s enthusiasm for art restoration happened to it. At first, the historical society and local townsfolk were up in arms. However, since 2012, Borja’s flagging tourist industry has been revived, and the proceeds from the picture’s fame help to fund not only a local museum but a care home for the elderly as well. 

The entire debacle quickly went viral on social media and the internet, leading Prof Van den Berg to comment on the underlying significance of social media as a field of praxis. As a nod to this aspect of modern culture, he specifically used hashtags (#sketching, #drawing, #painting, #tweetingGod, #findingthesacred) for the subtitles of his lecture. He said, “This is how the Twitter world in particular talks about God, in order to express multiple and compound understandings of daily life.” 

Evergreen Bible student

Prof Van den Berg’s love of practical theology dated back to his days as a student, when he said he learnt that “theology was not just a noun but a verb”. He said: “Practical theology’s description of the Divine in everyday life represents, for me, the relevance and topicality with which I associate theology.” He added that the title of his inaugural lecture directly relates to this understanding, as much as it can be strongly associated with his recent doctoral thesis at the University of Queensland, entitled Tweeting God: A practical theological analysis of the communication of Christian motifs on Twitter.

Expressions of faith in the mundane

In answering his question, mentioned at the outset, Prof Van den Berg said: “Perhaps there is more to be seen, heard, and read in everyday-life texts of the Cecilias of the world who take up their ‘paintbrushes’ ”. Stating that formal theological language has, in certain aspects, lost some of its impact and that many people have turned a deaf ear to the articulation of these truths, Prof Van den Berg concluded that “one must envision possible alternative descriptions, in the form of existing practices of #tweetingGod, finding the sacred in everyday life”.

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.
