Prof Fanie Snyman, retired Dean of the Faculty of Theology and Religion, is the first South African to publish a volume in the respected Tyndale Old Testament Commentaries series, which deals with the Bible books of Nahum, Habakkuk, and Zephaniah.

Against the backdrop of the Faculty of Theology and Religion’s 40th anniversary, Prof Fanie Snyman, retired Dean and research associate, has recently published a commentary in the Tyndale Old Testament Commentaries series based in Cambridge, England, on the prophetic books Nahum, Habakkuk, and Zephaniah of the Old Testament. What makes his book special is that Prof Snyman is the first and for the foreseeable future the only South African Old Testament scholar to be commissioned to publish in this distinguished commentary series. This commentary series is widely read and consulted in the English-speaking scholarly communities of Africa, Australia, Great Britain, New Zealand, the USA, and many European countries.

In a virtual ‘sit-down’ with Prof Fanie, he explained how a research volume of this type is usually compiled: It starts with a verse-by-verse analysis of the Bible books, looking at the literary aspects of how the passage was written as well as considering its historical, social, and cultural background. This is done to obtain a better overall understanding of the text. Secondly, a volume of commentary is not merely regurgitating knowledge that has already been generated. Prof Fanie says that “it must deliver new, fresh perspectives on the current state of research on these books. What can I contribute to the understanding of these writings?” To accomplish this, he had to pore over stacks of research on these prophetic works to be as current as possible with modern research.

First contributor from Africa

Dr David Firth, the series editor, says: “Over the nearly sixty-year history of the Tyndale Old Testament Commentaries, we have not previously had any contributors from Africa. That has now been put right with the release of Prof SD Snyman’s new volume on Nahum, Habakkuk, and Zephaniah. Prof Snyman has brought together his expertise on the prophetic literature of the Old Testament and theological awareness to present a fresh work on these often-neglected books. Through his careful attention to how these books functioned in their ancient setting and mastery of the secondary literature, he is also able to point to the enduring importance of each of these books for contemporary readers. As such, he has admirably fulfilled the brief for the series and produced a volume that will serve a new generation who come to these books.”

Prof Fanie affirms that the burning issues raised in each of these books regarding situations in ancient Israel often mimic comparable issues in our modern society. For example, he underscores how Nahum brings the misuse of political power to the fore, a current and topical point of contention. Prof Snyman says: “My aim was to create a vertical theological perspective of that historical situation against the backdrop of contemporary issues. I believe that these texts have a relevance for us and upon us today.”

Other international works

This book is the third one published internationally by Prof Snyman. In 2012, he published a book on the prophetic literature of the Old Testament together with a Dutch colleague in the USA. In 2015, he published a commentary on the book of Malachi in Europe. This book was awarded the UFS Book Prize for Distinguished Scholarship in 2017.

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.
