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.

Eight Kovsies have been selected as part of 100 delegates for the 2014 Brightest Young Minds (BYM) summit.

Thabiso Letselebe (Chief Delegate of the UFS BYM), Michael van Niekerk, William Clayton, Gopolang Kgaile, Thokozane Mahlanga, Mpho Sefo, Lisa Coetzee and Lehlohonolo Mofokeng will attend the BYM summit from 29 August to 2 September 2014 in Johannesburg.
BYM is a youth-driven non-profit organisation that identifies South Africa’s most passionate young people. The organisation equips these young leaders with the skills and networks needed to create positive change.

Each year, 100 participants are invited to a five-day summit, based on criteria of innovation, leadership, civic responsibility and academic accomplishment. Delegates discuss challenges facing the nation with respected leaders and then design start-up like solutions to these challenges.

Post-summit alumni have access to resources for success and BYM continues to encourage social entrepreneurship. BYM has demonstrated success in mobilising young people for nearly fifteen years.

BYM has been the launch pad for several successful business and social endeavours. Some of the ideas developed by BYM alumni include the AIDS Industry Management Standard, Taxi Smart Card System, MiniSass Water Monitoring System, Investec Young Women in Finance conference, Tertiary School in Business Administration, Twenty30 and Women in Engineering.

BYM attracts a diverse group of participants in terms of academic, racial, geographic and socio-economic backgrounds. In a society marred by divides, BYM is proving the power of diversity. The organisation’s participants would not be as successful in moving the nation forward if it were not for the diversity of their experience.
