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.

Protest actions on the Main Campus
2008-03-12

Staff and students are kindly requested to take note of the following protest actions that will take place on the Main Campus.

As a result of a dispute over the status of roads on campus, permission was granted by the municipality and the court, in the presence of the university lawyer for the three actions. Strict conditions have been set for these protest actions.

a.) On Wednesday, 12 March 2008, Satawu and Nehawu will picket in front of the Main Building from 09:00 to 12:00. Three hundred persons will possibly attend this event. Marchers are not allowed within 10 meters from the Main Building and there will be 45 marshals present. This is not a march and no memorandum will be handed over. There may be no speeches.

b.) On Thursday, 13 March Nehawu will again picket in front of the Main Building from 13:00 to 14:00. This event must be peaceful. Only 125 Nehawu members may participate and protesters may not break away from the big group. They may not come within 10 meters of the Main Building. Twenty five of the protesters will be marshals. This is not a march and no memorandum will be handed over. No speeches may be made.

c.) On Friday, 14 March a march of Cosatu and Nehawu will take place. This march will probably be joined by a big number of people.

The march will continue through the Nelson Mandela Gate and will enter the campus grounds, but will be limited to the incoming lane of Chancellors Avenue from the Main Gate to the crossing with Alumni Avenue (in front of the Odeion). Speeches will be made and a memorandum will be handed over.

The march will reach the campus at 10:00 and from then the Nelson Mandela Gate will be closed for all traffic. The march must be finished by 14:00. The marchers will return to the city centre and could cause a traffic problem in Nelson Mandela Avenue.

The South African Police Service and the UFS’s Protection Service will monitor all these actions. Staff are kindly requested to use alternative gates to the Nelson Mandela entrance on Friday. Academic activities continue as normal.
