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.

UFS obtains court interdict against protesting students - classes will resume on 22 October 2015
2015-10-21

A court interdict was successfully granted to the University of the Free State (UFS) this afternoon against conduct by anyone who intends to damage the property of the university or who interferes with the rights of others.  Any disruption that happens as from now, will be illegal and the UFS will have the right to call upon the South African Police Service (SAPS) to enforce the interdict.

“The interdict does not prevent students from exercising their right to protest or to use any form of demonstration that does not threaten people or property. In doing this, management believes that it is in keeping with its double responsibility of guaranteeing all students’ rights and safeguarding the university’s staff, academic activities and property,” says Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS.

“The university management is still open to engage with students in discussing the implications of their demands for a zero percent fee increase,” says Prof Jansen.

All three campuses of the UFS will be open tomorrow (22 October 2015) and all academic programmes and support services will resume as normal. Order will be maintained on the campuses, using the powers of the interdict. No one will be allowed to enter or exit the campuses without a valid UFS staff or student card.
