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.

SRC President Njabulo Mwali says that the presence of international students on the Qwaqwa Campus is very welcome as it enables students from all over the world to learn from each other.  He was addressing the International Student Council’s welcome function for international students.

“One important area where South African students can learn a lot from international students is hard work. It is an open secret that many of us, as South Africans, are not as persistent as we should be. We give up easily,” he said to an audience of students mainly from Zimbabwe, Kenya, Ethiopia, and Nigeria.

Speaking on behalf of the Rectorate, the Registrar: Systems and Administration, Dr Karen Lazenby, assured international students that the UFS is committed to their emotional and physical wellbeing.

International students face various challenges

“Having been an international student myself, I fully understand your various challenges. If you have any ideas on how we can make your stay here as memorable as possible, please help us to help you,” she said.

Both Drs Elsa Crause and Dipane Hlalele, respectively Campus Vice-Principal: Academic and Research and Acting Campus Vice-Principal: Support Services, congratulated students on choosing the Qwaqwa Campus.

“Our campus will give you many opportunities to reinvent yourself both as a person and a student,”   Dr Crause said.

Dr Hlalele added: “International experience is fascinating as it does not only provide different types of knowledge and truth, it also enriches the campus with an African and international footprint.”

The Office of International Affairs also presented its services to students.
