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.

University helps design new test of academic literacy for postgraduates
2012-09-04

The Inter-institutional Centre for Language Development and Assessment (ICELDA), of which the University of the Free State (UFS) is a founding partner, has secured a joint agreement with the Language Centre at the Radboud University Nijmegen in the Netherlands to design and develop another test of academic literacy for postgraduate students.

ICELDA is a partnership between four multilingual South African universities: Pretoria, Stellenbosch, North-West and Free State.

This design that ICELDA is coming up with will focus mainly on diagnostic purposes and follow in the footsteps of TALPS, the current test of academic literacy for postgraduate students at the four universities.

Prof. Albert Weideman, Head of the Department of English says TALPS has recently been the topic of a redesign and in-depth analysis undertaken by Colleen du Plessis, a junior lecturer in the Department of English for her master's dissertation. She is developing two further versions of it for ICELDA and the new project will involve Rebecca Patterson, who will do her long assignment for honours on the diagnostic value of the current test. A former doctoral student of the Department English Tobie van Dyk will be the project leader.

“The rationale for the project is that one can no longer take the academic literacy levels of postgraduate students for granted. We wish the investigating and development team that Tobie will put together, every success.”
