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.

Honorary Professor delivers inaugural lecture in the Faculty of Theology
2010-10-27

Prof. Peter Lampe.

Prof. Peter Lampe recently delivered his inaugural lecture as an Honorary Professor in the Department of New Testament in the Faculty of Theology of the University of the Free State (UFS).

The title of Prof. Lampe’s inaugural lecture was Theology and rhetorics: how do "res" and "verba" relate to each other, in which he addressed the fundamental question of the role and importance of words and the issue/content in theology. Can content simply be conveyed in any manner? Also in theology, Martin Luther observed that some theologians’ works contain words (verba) and those of others the content (res). In his inaugural lecture, Prof. Lampe pointed out that our knowledge of God/reality specifically has to be construed through the use of words. Words and terminology therefore have to be selected with circumspection. Res and verba stand in close relation to each other.

Prof. Lampe declared that in the post-modern world, a “competition” exists for the best constructed worldview and theologians could make a significant contribution to the construction of a better reality through better judgement of the words they use. 

Prof. Lampe, currently the Chair of New Testament Theology at the University of Heidelberg in Germany, has a rich and varied history in the field of theology. Having attained degrees in theology, philosophy and archaeology in Gottingen, Rome and Berne, Prof. Lampe has enjoyed an illustrious professional career. After receiving his Ph.D. at the University of Berne and teaching New Testament Studies there, Prof. Lampe held the Chairs of New Testament Studies in Virginia (USA) and History and Archaeology of Early Christians in Kiel (Germany), before being appointed to the post he currently holds.

In 2003 he was awarded the German Ecumenical Preaching Award and in Turkey he was the leader of an expedition that discovered the long-lost Montanist headquarters of Pepouza and Tymion.
