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.

Kovsie students have often showed that a friend in need is a friend indeed. Several student organisations have recently started initiatives to lessen the burden on needy students, and on the broader community.

It is because of these initiatives that donations of food, commodities and clothes reached the No Student Hungry (NSH) Bursary Programme at the University of the Free State.

The Rag Community Service and NSH offices are extremely grateful to students and staff for their selfless donations, also in respect of the difference these initiatives are making to Kovsies’ chances of having a better future.

The food and commodities will be distributed to the community, while the clothing donations are used for regular clothing sales in order to raise funds.

The food donations included a substantial donation from the support organisation, Gift of the Givers. The organisation heard about the NSH Bursary Programme and, due to the scope of the student-hunger problem, decided to become involved.

“This is an excellent initiative, and the passion with which it is driven motivated us to make a donation,” said Ms Emily Thomas, representative from Gift of the Givers.

Ms Karen Scheepers, Assistant-Director: Student Life responsible for Rag Community Service, said the recent donations and initiatives are proof that the Kovsie community really cares for each other.

“I found it amazing how willing students were to help and to give. From the moment we asked for help, students arrived at our offices with loads of stuff.”
