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.

Prof Ruth Goveia, a piano lecturer at our university’s Odeion School of Music (OSM), was chosen to serve on the jury of the 5th Unisa National Piano Competition. This will take place from 11 to 18 July 2015 at the ZK Matthews Hall on the Unisa Muckleneuk Campus in Pretoria.

Prof Goveia holds a doctorate in Music in Piano from the prestigious Jacobs School of Music at Indiana University in the USA, and has a master’s degree in Piano Performance from the College-Conservatory of Music at the University of Cincinnati, also in the USA. Prof Goveia is an experienced adjudicator, and is regularly engaged for both national and international piano competitions, festivals, and examinations.

She is a dedicated teacher, who enjoys working with both students and professional musicians. Several of her students have excelled in competitions and examinations, and enjoy successful careers.

The Unisa National Music Competition was founded with the main objective of providing young South African pianists with the necessary experience, requirements, and procedures of an international piano competition. The winner of the national competition has automatic access as a participant in the next scheduled Unisa International Piano competition. The prescribed repertoire requirements of the national competition always correspond closely to those of the next Unisa International Piano Competition.

Competitors will be subject to the same adjudication criteria and processes applicable to international piano competitions. The Unisa Music Foundation’s next piano competition will have a jazz category running parallel to the classical category.
