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.

Different religions introduced at UFS forum
2010-08-18

The Inter-Religious Forum (IRF) of the Faculty of Theology at the University of the Free State (UFS) has started a discussion series which offer the opportunity to different religions to introduce themselves. According to Rev. Maniraj Sukdaven from the Department of Religion Studies at the UFS, the purpose of the discourse series is to get to know more about one another’s religion within an atmosphere of respect.

During the last IRF meeting, Mr Ronnie Rosen, leader of the Jewish community in Bloemfontein, gave a talk about the Jewish religion. According to him there is a wide range of Jewish people.

“The one thing, however, that all Jewish people have in common is the Torah or Law-Book. There are 613 instructions that help a Jewish person to organise his life according to the Jewish way of life. For example, a Jewish person who wants to obey the Torah would not consume dairy products and protein together. This life style is not only regarded as a religion, but a way of life, which constantly makes a person aware of his relationship with God,” he explained.

Another interesting fact that transpired during the discussion was that, for the first time in the history of the world, there are more Jews in Israel than in other concentrated areas across the world. Five (5) million Jews are currently living in Israel, while the remaining 10 million Jews are spread across the world.

During the meeting of the IRF forum, persons from amongst others the Baha’i, Hindu and Christian religions participated in the discussion. Other religions that have already been discussed are Hinduism, Christianity, Islam and Rastafarians.

The IRF will also be involved in the structuring of course material about the different religions and an inter-religious conference will be part of the IRF’s programme in 2011.

The IRF is the only institution of its kind at South African universities.
