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.

New Research in Hebrew Language and Culture
2014-01-17

The newly formed Department of Hebrew at the university is hosting an international conference from 27 to 29 January 2014. The conference has speakers from Israel, the United States, Canada, the United Kingdom and Saudi Arabia, as well as South Africa, Zambia, Congo and Nigeria. The goal of the conference is to highlight recent research in Hebrew language and culture by bringing international scholarship to the university and by highlighting the importance of the African context as a conceptual space for research on Hebrew. The rich cultural heritage of Hebrew finds particular resonance in Africa through the Hebrew Bible (Old Testament).

Some highlights from the conference include new research on the use of the ancient Hebrew script by Jews in the Persian and Roman periods as a means to maintain their religious and ethnic identity in times of distress, linguistic research on metaphors in the Hebrew Bible (Old Testament), Jews and non-Jews in the Hebrew and Yiddish writings of the South African author Morris Hoffman, the development of a rabbinic prayer for rain in the land of Israel and in South Africa, pedagogical advances in teaching Hebrew in Africa, and translation of the Hebrew Bible (Old Testament) as a means of reshaping VaTsonga cultural identity. 

The study of ancient and modern Hebrew language and culture provides important insights into the complex cultural situation in modern Africa, generally, and South Africa, in particular. The use of language by minority religious and ethnic groups can provide a powerful force for identity in turbulent political realities. Religious texts can be re-contextualised to provide guidance in new cultural contexts or translated to enhance and empower local societies. 

Venue: CR Swart Auditorium
