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.

Urgent notice: critical shutdown of UFS IT system
2014-08-20

ICT Services is experiencing a degradation of service due to a technical fault in one of our key mass storage devices, which calls for a critical shut-down of the facility as soon as possible. The implication of the error condition is of such a nature that we need to decommission in excess of 550 servers before the actual error can be addressed. In failing to do so in a structured manner, we run the risk of a total system outage and a prolonged repair process of the total server infrastructure due to possible damage to disks and processing facilities.

It is foreseen that ICT will commence with the decommissioning of the servers from 14:00 on Saturday 23 August 2014, repair the error and recommission the facilities by 20:00 on Sunday 24 August 2014.

The following services will therefore be unavailable during this period:

• All learning platforms (BlackBoard, etc.)
• All administrative systems
• Internet access
• Email services

PLEASE NOTE: Students are requested to retrieve all information they require from BlackBoard during this period, before the systems are shut down.
