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.

'Physical education at school level important,' says Minister
2010-09-16

At the conference were, from the left: Monique de Milander, Prof. Johan Bloemhoff, Rev. Makhenkesi Stofile, Emile Langeveld and Riaan Schoeman.

A record number of four staff members from the Department of Exercise and Sport Sciences at the University of the Free State (UFS) presented papers at the South African Sport and Recreation Conference (SASreCon). This conference was presented by Sport and Recreation South Africa (SRSA) from the National Department of Sport and Recreation. This is South Africa’s primary national conference on sport and exercise science.

The conference, that was hosted by the University of KwaZulu-Natal in Durban with the theme Sport, Recreation and Physical Education – An Essential Triad, highlighted the important triangular relationship between sports science, recreation and physical education. A host of leading South African and international speakers presented papers on key topics that are relevant to the South African sports and exercise landscape.

The four staff members who attended also had the opportunity to meet the Minister of Sport and Recreation, Rev. Makhenkesi Stofile. The Minister reiterated the importance of physical education at school level to ensure that South Africa can compete against the best in the world at stadiums such as the iconic Moses Mabhida Stadium, where the function was hosted.
