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.

Kovsies has become the first team to successfully defend the Varstiy Netball title when they beat Tuks 49-42 in the 2014 final in Pretoria on Monday 20 October.

University of Pretoria (Tuks) might have been unbeaten for the entire 2014 tournament, but this did not hinder Kovsies in becoming the Varsity Netball champions for a second consecutive time.

From the outset, both these furiously focused teams fought hard and only after ample turnovers could Kovsies finally manage to open the score board.

The Mostert sisters, Karla and Tanya, won a couple of crucial balls, leaving the UFS dominating possession in the opening exchanges.

When Tuks eventually got to scoring, they could not stop the UFS from rushing to a 9-3 lead after the first ten minutes. The visitors had established a 13-5 advantage by the first break, keeping the Pretoria crowd quiet.

The home side came back shooting in the second quarter with great determination, fighting their way back into the game. Tuks ran hard, needing to work hard against Kovsies, who still managed to be in the lead with 22-16 at half-time.

Kovsies made good use of their power play early in the third quarter to stretch their lead further to 30-22. They made the most of their opportunities, going into the final quarter with a 39-31 upper hand.

Even though Tuks made a couple of changes during the final break, they could not avoid defeat in the end.

Kovsies’ Lauren-Lee Christians was also the player of the match, while the champion’s captain, Karla Mostert, was announced as the Player of the Tournament.

This hard-working defender made a number of crucial interventions alongside her sister Tanya in the final. Karla proved that she was the fans’ tournament favorite, claiming the most votes and winning a Samsung S4.
