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 Department of Chemistry moves into world-class facilities

The University of the Free State’s (UFS) Department of Chemistry recently moved into the first and second phases of the southern wing of the upgraded Moerdyk and annex building in which the department is situated. The wing is part an extensive project to upgrade the building and its facilities.

At a total costs of R40 million for the upgrading of the building and R30 million for the equipment, this is the biggest project of its kind in the history of the UFS.

The upgrading is taking place in four phases, of which the largest part is the southern wing. Researchers and undergraduate students recently moved into this part of the building, which consists of the first- and second-year laboratories. The laboratories consist of, among others, larger and safer venting and research-focused facilities as well as enough storage for the department’s equipment. Although one of the water-cooling systems on the roof of the building recently caught fire, all classes, practical and research work is going ahead without any disturbance.

“The putting into service of the first two phases is a milestone for the department. The project is almost half way and, when it is completed by the middle to end of 2009, we will boast with some of the best research and undergraduate laboratories in the country. It will also increase our leadership in advanced training on the continent and will strengthen the UFS’s role in the international chemistry arena,” says Prof. André Roodt, head of the department.

According to Prof. Roodt advanced research on fuel and nano particles (this is particles as big as one hundred thousandth of a human hair strand) will be conducted in the completed laboratories as part of the UFS’s research cluster initiative. Other research such as anti cancer remedies, research on various chemical processes and research on biological pharmacological remedies will also be done.

“During the past three years the department has made a significant impact on research in chemistry worldwide. Our academics are publishing in some of the world’s foremost chemistry journals and various presentations are made at international conferences. The upgraded facilities will ensure that we continue building on our high quality research and it will also ensure that our students can compete with the best in the world,” says Prof. Roodt.
