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.

Distinguished Kovsie medical student bestowed with Abe Bailey Bursary
2013-10-14

14 October 2013

Residence head, SRC member, Golden Key International Honour Society member and now: Abe Bailey scholar as well. These are some of the achievements and leadership titles that Michael van Niekerk, a fourth-year MBChB student at our university, has under his belt.

One of 18 South Africans countrywide, Van Niekerk is to visit institutions in England and Scotland as a recipient of the prestigious Abe Bailey Travel Bursary for 2013. The scholarship acknowledges excellence in academics, leadership and community service and is awarded annually to third-year students and/or junior lecturers not older than 25 years of age.

The recipients of the 2013 Abe Bailey scholarship leave for Cape Town on 20 November 2013 to attend a two-day orientation process. Following this, they will then travel to London and Edinburgh, where they will visit universities, as well as places of interest such as London’s House of Lords.

Van Niekerk, who recently visited the USA as part of the Golden Key International Honour Society’s International Scholar Laureate programme, says it is an incredible honour to be this year’s Abe Bailey recipient for the UFS. "I am very blessed to not only excel in the medical field, but also in leadership and other aspects and I believe that this is absolutely grace from Above. I believe that this is an opportunity and a step to a better future. I don’t believe in being average and believe that this is an opportunity to prove myself and achieve more."

This Kovsie student says he has great plans for the future. "If it is God’s will, I would very much like to specialise in neurosurgery, cardiothoracic surgery or trauma surgery. I would like to be part of the Rhodes Scholarship and would strive to reach it."
