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.

Students get a place to rag
2008-01-16

 

A jol place where students from the University of the Free State (UFS) can socialise during events such as rag and intervarsity was officially handed over to the UFS by the builders this week.

The Jol place, which is situated on the Western Campus, has ten float building areas, each with its own power points (currently temporarily) and container (also temporarily). There are also outside taps and high-mast lights on the premises and a large area has been paved. The covered area includes an open stoep, kitchens, a bar, and a stage with artists’ dressing rooms as well as bathrooms for men and ladies and for persons with disabilities. The premises, that includes wooden and concrete benches, can accommodate 1 200 people.

The total project cost for this facility was R6,3 million, of which just over 50% was contributed by Absa.

Attending the hand over ceremony were, from the left: Prof. Frederick Fourie (Rector and Vice-Chancellor of the UFS), Mr Natie Botes (from the building company Ströhfeldt Sikeye Joint Ventures), Ms Edma Pelzer
(Director: Physical Resources and Special Projects and the UFS), Dr Natie Luyt (Dean of Student Services), and Jolice Neniëls (forth-year LL.B. student).
