Water footprint important but misunderstood indicator
Water footprinting is the future of water conservation
The Water Footprint (WF) of a product, process or person provides an indication of how much fresh water is used, both direct and indirect, to produce a product, drive the process or lead a lifestyle. Although it is a very important indicator it is often misunderstood. Popular media contribute to this misunderstanding as they often use the WF to illustrate the large quantities of water used to produce a product without explaining what the footprint actually means.  

An example is a single kilogram of beef that has an average global WF 15 415 litres. This indeed sounds scary, but when one places it in context, the total WF includes 14 414 litres green water, 550 litres blue water and 451 litres grey water. Green water is the evapotranspiration of precipitation (rain), blue water is the fresh water from dams, rivers and underground sources, while grey water is the amount of fresh water required to dilute polluted water to acceptable levels.

According to Frikkie Maré, a lecturer at the Department of Agricultural Economics at the University of the Free State (UFS), the WF concept provides a new look at water conservation and sustainability. “Although the WF is not an indicator of sustainable water use, it is a useful tool to calculate total water demand and is used in the estimation of sustainability. Traditionally, water conservation was focused on the direct water use of individuals (time taken to shower, leaking taps etc.), but the WF now provides a tool to focus attention on total water demand.”

The Water Footprint Network assists individuals with this new trajectory on the water conservation front with the personal water footprint calculator that allows individuals globally to determine their personal water demand through their direct and indirect water usage. Maré believes this can cause the necessary paradigm shift in the aqua status quo by creating awareness among consumers on their total water demand.

With Water Week underway from 17-23 March 2018, UFS students and staff members are urged to make use of the personal water footprint calculator in order to become aware of the real importance of fresh water in our everyday lives.

Prof Hermie van Zyl, former Dean of the Faculty of Theology at the University of the Free State (UFS), was recently awarded the Ds Pieter van Drimmelen medal by the South African Academy of Science and Arts (SAAWK) for his contribution to Afrikaans Bible translation and other translation work.

Prof Van Zyl was part of the team that published the Interlinear translation of the Bible (New Testament) in Greek and Afrikaans. This translation takes the reader from the original text (Greek), to an almost verbatim version, to a rough translation, and, ultimately, to a more polished, finished translation in the target language of Afrikaans.

Other translations Prof Van Zyl has been involved in include the Afrikaans Bible for the Deaf (published in 2008), the direct translation of the Bible (of which the New Testament and the Psalms have already been published), the New Living Translation, the Parallel New Testament, and the Reference Bible. He is the first lecturer from the Faculty of Theology at the UFS to receive an award from the SAAWK.

“It is a wonderful privilege and an honour and really came out of nowhere,” said Prof Van Zyl. He added that he is grateful that, amongst all the wonderfully talented people at the UFS, he could make a modest contribution. He mentioned that the collegial conversations, seminars, and other discussions in the faculty over the years, were very stimulating. He singled out Prof Jan du Rand and Prof Francois Tolmie (another former Dean of the Faculty and long-time colleague in the department of New Testament Studies) as inspiration.

The official presentation of the medal will take place in the Atterbury Theatre in Pretoria on 29 June 2016.

Prof Van Zyl was employed in the Faculty of Theology at the UFS for 29 years until his retirement in 2013. He is currently a Research Fellow in the Department of New Testament, and still lectures on occasion.
