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.

The Odeion School of Music (OSM) at the University of the Free State (UFS) will be hosting one of the world’s foremost piano duos. Nettle and Markham perform in the main concert halls of Europe and with major British orchestras such as the London Philharmonic, the RPO, the CBSO, and the ECO as well as other international orchestras. They also participate in major international festivals such as the Bath, Harrogate, Berlin, Schleswig-Holstein, and BBC Proms.

The British duo have been delighting audiences throughout the musical world for nearly forty years and will perform at the Odeion on the UFS Bloemfontein Campus on 20 October 2016. David Nettle and Richard Markham are considered one of the most entertaining and musically satisfying partnerships performing today.

"We have not heard here until now a piano duo of such exceptional quality. The understanding of the music by both partners is so good that you cannot distinguish by hearing which of them picks up the musical theme. At the same time it is playing full of colour and spontaneous musicality, stirring and ravishing," Vecemi Praha said.

Nettle and Markham's varied recital and concerto repertoire encompasses not only standard works, but also their own distinctive transcriptions. Their highly praised recordings reflect the range of styles they are known to assimilate effortlessly, from Stravinsky’s The Rite of Spring to Sir Malcolm Arnold’s Concertos for two pianos.

In addition to their regular concert schedule, recent seasons have seen them devoting large amounts of time to preparing new recordings - the complete four-hand works of Schumann and Saint-Saëns being the first in a series of projects designed to keep them busy from now until their 40th anniversary seasons in 2017 and 2018.
