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.

Wayde van Niekerk became the only South African, and the fourth athlete in the world, to clock sub-20-seconds in a 200 m race on Tuesday 14 July 2015. With this winning time, he became the fourth member of the prestigious quartet, consisting of Michael Johnson, LaShawn Merritt, Isaac Makwala and himself.

The Kovsie gold medallist’s ground-breaking performance saw him beat world-class 200 m specialist and last year's Diamond League race winner, Alonso Edward of Panama.  Van Niekerk crossed the finish line half a metre ahead of Edward, who was followed by Fujmitsu Kenji of Japan in the third place.

Van Niekerk's 19.94-time at the Diamond League meeting in Lucerne (Switzerland) set a national record, and improved on his personal best. In 2010, he claimed the World Junior Championship title in Moncton, Canada, by covering 200 m in 21.02 seconds.

Recently, he made history by defeating the London 2012 Olympic Games champion, Kirani James, of Grenada in the Caribbean.

On 4 July 2015, he surged 0.79 seconds ahead of Kirani in his number five lane, becoming the first African to cover 400m in less than 44 seconds. The Kovsie student won the race at 43.96, occupying 10th place on the International Association of Athletics Federations (IAAF) Diamond League all-time list.

Kovsies were still celebrating the gold medalist’s South African record-setting time of 44.24 on 13 June 2015 when he dominated the Diamond League meeting. At the previous race in New York, Van Niekerk improved on his own national record of 44.38. With an impressive dash to the finish line at that particular event, he surpassed Christopher Brown’s 400 m record.

In addition to the country’s record, Van Niekerk made his name as one of the continent’s record-breakers. On 7 June 2015, he broke the 1986 African 300 m record. Van Niekerk replaced Ivorian Gabriel Tiacoh’s best time of 31.74 with a 31.63 championship win at the Birmingham Diamond League meeting.  Simultaneously, he bettered Morné Nagel’s 2006 South African national record.

Following his outstanding performance, he was positioned in 10th place on the world list in the men’s 300 m.
